FIELD OF THE INVENTION

The invention provides therapeutic compositions, combinations, and uses thereof to treat disorders mediated by transcriptional proteins Ikaros (IKZF1) and/or Aiolos (IKZF3) via degradation of these proteins through the ubiquitin proteasome pathway.

BACKGROUND

The Ikaros family is a series of zinc-finger protein transcription factors that are important for certain physiological processes, particularly hematopoietic cells, and lymphocyte development (see Fan, Y. and Lu, D. “The Ikaros family of zinc-finger proteins” Acta Pharmaceutica Sinica B, 2016, 6:513-521). Ikaros (IKZF1) was first discovered in 1992 (see Georgopoulos, K. et al. “Ikaros, an early lymphoid-specific transcription factor and a putative mediator for T cell commitment” Science, 1992, 258:802-812), and over the subsequent two decades four additional homologs have been identified: Helios (IKZF2), Aiolos (IKZF3), Eos (IKZF4), and Pegasus (IKZF5) (see John, L. B., and Ward, A.C. “The Ikaros gene family: transcriptional regulators of hematopoiesis and immunity” Mol Immunol, 2011, 48: 1272-1278). The distribution of various members of the Ikaros protein family within the body varies significantly.

Ikaros, Helios, and Aiolos are primarily found in lymphoid cells and their corresponding progenitors, with Ikaros additionally detected in the brain, and Ikaros and Helios detected in erythroid cells. Eos and Pegasus are more wide spread, and found in skeletal muscle, the liver, the brain, and the heart (see Perdomo, J. et al. “Eos and Pegasus, two members of the Ikaros family of proteins with distinct DNA binding activities: J Biol Chem, 2000, 275:38347-38354; Schmitt, C. et al. “Aiolos and Ikaros: regulators of lymphocyte development, homeostasis and lymphoproliferation” Apoptosis, 2002, 7:277-284; Yoshida, T. and Georgopoulos, K. “Ikaros fingers on lymphocyte differentiation” Int J Hematol, 2014, 100:220-229).

Ikaros is important for proper lymphocyte development. Deletion of the exons encoding the first three N-terminal zinc fingers leads to mice lacking T-cells, B-cells, natural killer (NK) cells, and their progenitors. Genetic alterations in Ikaros are correlated with a poor outcome in the treatment of acute lymphoblastic leukemia (ALL). Ikaros and Aiolos are involved in the proliferation of multiple myeloma cells and lymphoma cells.

Multiple myeloma (MM) is a plasma cell malignancy typically characterized by the abnormal production of monoclonal immunoglobulin, bone marrow involvement, renal dysfunction, immune dysfunction, and skeletal damage. In the United States, MM represents nearly 1.8% of all new cancers. Although outcomes for subjects with MM have improved substantially over the past several decades, the disease remains incurable with a predicted five- year relative survival rate currently of 53.9%. As available therapies are not curative, almost all patients ultimately progress.

Management of MM historically included chemotherapy, including alkylating agents together with corticosteroids. Treatment was further advanced in the 1980’ s with autologous stem cell transplants. In the 1990's the discovery of thalidomide (first-in-class immunomodulatory imide drug, IMiD®) efficacy in myeloma led to large shifts in treatment regimens and improvements in patient outcomes. The follow-on approved IMiD®s, lenalidomide and pomalidomide, are now widely used to treat MM, as is the first-in-class agent thalidomide. This class of agents binds the E3 ligase substrate-recognition adapter protein cereblon (CRBN) and promote the degradation of Ikaros (IKZF1) and Aiolos (IKZF3), resulting in antitumor effects, effects on the tumor microenvironment and immune modulation resulting in T-cell priming and antitumor activity. Many patients with MM are treated with multiple regimens containing one of these IMiDs. These drugs are now considered standard of care for the treatment of MM in numerous lines of therapy, in combination with agents including dexamethasone, anti-cluster of differentiation 38 (CD38) antibodies, and proteasome inhibitors, such as bortezomib. Although these agents have been successful in prolonging the progression free survival of patients with MM, patients generally relapse with shorter periods of progression free survival after each relapse. Recent studies with novel agents, belantamab and selinexor displayed improved outcomes in multiclass refractory myeloma resulting in recent FDA accelerated approvals; however, response rates were low (26- 31%) and progression free survival intervals short (3.7-4.9 months), thus underscoring the continued unmet medical need among these patients.

Non-Hodgkin’s Lymphoma (NHL) is a heterogenous group of lymphoid malignancies originating from T, B or NK cells. It includes diffuse large B-cell lymphoma, anaplastic large-cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma, mantle cell lymphoma, peripheral T-cell lymphoma, follicular lymphoma, cutaneous T-cell lymphoma, lymphoplasmacytic lymphoma, marginal zone B-cell lymphoma, MALT lymphoma, and small-cell lymphocytic lymphoma. B-cell NHL predominates, while T-cell lymphomas are less common. Among new diagnosed patients with aggressive NHL, chemotherapy-based regimens including cyclophosphamide, vincristine, prednisone and daunorubicin (referred to as CHOP) remain the mainstay of therapy. In B-cell aggressive lymphomas, rituximab in combination with CHOP is the main therapy administered to new diagnosed patients. In some patients, particularly those with T-cell NHL, initial chemotherapy is followed by autologous stem cell rescue. In relapsed refractory populations, various targeted agents have been developed, thus improving treatment options in multiple subtypes of NHL, however these treatment options tend not to be curative. Additionally, the NHL subtypes are biologically heterogeneous limiting the development of therapeutic agents broadly across indications.

In new diagnosed patients with aggressive lymphoma, initial treatment is frequently intense and administered with curative intent. Other than the addition of rituximab to CHOP in B-cell NHL and brentuximab to CHOP in anaplastic large cell lymphoma (ALCL), no other novel targeted agent has demonstrated survival improvements and therefore no others have been approved in treatment of naive patients. Recent therapeutic advances in relapsed NHL include Bruton Tyrosine Kinase (BTK) inhibitors, particularly for mantle cell lymphoma (MCL) and more indolent forms of NHL, chimeric antigen receptors T-cell (CAR-T) therapies which have been approved for diffuse large B-cell lymphoma (DBLCL) and MCL, and novel antibody drug conjugates like polatuzumab, belantamab, or tafasitamab which have been approved for DLBCL. Drugs recently approved for T-cell NHL include romidepsin, belinostat, and brentuximab. Relevant to the NHL population being studied in this protocol, lenalidomide has demonstrated clinical activity in both B-cell and T-cell NHL, including MCL, DLBCL and peripheral T-cell lymphoma (PTCL). Lenalidomide was studied in the relapsed/refractory (r/r) MCL population and was approved by the Food and Drug Administration (FDA) in June 2013 following results from the Phase II EMERGE study which examined the efficacy and safety of lenalidomide in r/r subjects with MCL following bortezomib (overall response rate [ORR] 28%; median duration of response [DOR] 16.6 months). Lenalidomide is also active in DLBCL and PTCL. While lenalidomide and other novel targeted therapies have a modest to good response rate, durability of responses tends to be short across most NHL subtypes. Once patients relapse following 1-2 treatment regimens, the median duration of response tends to be low, and is dependent on patients having sufficient performance status and organ function to tolerate these therapies. Therefore, there remains an unmet medical need among patients with r/r NHL.

Protein degradation is a highly regulated and essential process that maintains cellular homeostasis. The selective identification and removal of damaged, misfolded, or excess proteins is achieved via the ubiquitin-proteasome pathway (UPP). The UPP is central to the regulation of almost all cellular processes, including antigen processing, apoptosis, biogenesis of organelles, cell cycling, DNA transcription and repair, differentiation and development, immune response and inflammation, neural and muscular degeneration, morphogenesis of neural networks, modulation of cell surface receptors, ion channels and the secretory pathway, the response to stress and extracellular modulators, ribosome biogenesis and viral infection. Covalent attachment of multiple ubiquitin molecules by an E3 ubiquitin ligase to a terminal lysine residue marks the protein for proteasome degradation, where the protein is digested into small peptides and eventually into its constituent amino acids that serve as building blocks for new proteins. Defective proteasomal degradation has been linked to a variety of clinical disorders including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, muscular dystrophies, cardiovascular disease, and cancer among others.

Patent applications that describe certain protein degraders include WO 2020/210630, WO 2020/006262, WO 2020/010227, and WO 2020/010177.

It is an object of the present invention to provide new compositions of matter, combinations, formulations and uses thereof as well as processes of preparing compounds for the treatment of medical disorders mediated by Ikaros or Aiolos.

SUMMARY OF THE INVENTION

Compound 1 is a small molecule anti-cancer agent that binds with high affinity to the cereblon E3 ligase thereby creating a new surface on cereblon that interacts with IKZF 1 and IKZF3 (see WO 2020/210630). As a result, IKZF1 and IKZF3 are efficiently ubiquitinated by the cereblon E3 ligase and degraded by the proteasome. The high cereblon binding affinity of Compound 1 enables rapid, deep, and durable degradation of IKZF 1/3 resulting in potent activity in cancer cells, for example including but not limited to, hematopoietic cancers such as multiple myeloma and the multiple types of Non-Hodgkin’s Lymphoma.

It has now been discovered that Compound 1, and other compounds described herein, can be administered to treat disorders mediated by Ikaros (IKZF1) and/or Aiolos (IKZF3) in a low dosage regimen once or twice a day, optionally with a drug holiday, in highly effective treatment regimens. For example, it has been discovered that anti-cancer treatment can be effective for a patient using one of the compounds described herein with a dosage of not more than about 500, 450, 400, 350, 325, 300, 275, 250, 225, 200, 175, 150, 125 or even 100, 75, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, or 1 micrograms (μg) once a day (QD) or twice a day (BID). In certain embodiments, the patient is an adult (typically a human of at least 100 pounds or more, and sometimes even 125 or 150 pounds (e.g., 70 kg or more and at least typically 18 years old or more). In an alternative embodiment, the patient is pediatric (and may be less than 100, 125 or 150 pounds and typically less than 18 years old). Not only has it been discovered that Compound 1 is effective as a low dose therapy, but it can also be delivered with a drug holiday which is advantageous to the patient. For example, Compound 1 can be delivered once or twice a day for 21 days followed by a drug holiday of 7 days. Alternative dosing regimens are also useful, for example, including but not limited to those that increase or decrease the drug holiday by 1, 2, 3, 4, 5, 6, or 7 days.

In certain embodiments Compound 1 or another compound described herein modulates the patient’s immune activity. For example, it has been discovered that Compound 1 activates proliferation of cytotoxic T-cells, which can be critical to anti-cancer therapy.

Compound 1 or another compound described herein in a non-limiting embodiment can be administered daily or intermittently with dexamethasone. In certain embodiments, dexamethasone or another corticosteroid or another immunosuppressant or anti-inflammatory agent is administered every day without a drug holiday for the 28-day cycle. In other embodiments, the dexamethasone or another corticosteroid or another immunosuppressant or anti-inflammatory agent is administered with a drug holiday, which may be the same or different from that of Compound 1 or another compound described herein.

In one aspect of the present invention the low dose Ikaros (IKZF1) and/or Aiolos (IKZF3) degrading compound is Compound 1 or a pharmaceutically acceptable salt thereof.

Compound 1 has a high binding affinity to cereblon (dissociation constant Kd = 0.9 nM). Compound 1 promotes the degradation of >75% of steady state IKZF1 in multiple myeloma cells within 1.5 hours at 0.3 nM. The high binding affinity and degradation catalysis of Compound 1 enables potent cell growth inhibition in both previously untreated NCIH929 multiple myeloma cell lines (96% maximal growth inhibition, mean half maximal inhibitory concentration IC₅₀ of 0.071 nM) and NCIH929 cells made resistant to both lenalidomide and pomalidomide (70% maximal growth inhibition, mean IC₅₀ of 2.3 nM). The compounds described herein can be used to treat cancer cells that are resistant, refractive or unresponsive to standard of care therapies for cancers mediated by IKZF1 or IKZF3, including IMiDs including pomalidomide or any of those described in the Background or Detailed Description.

As shown in Examples 12, Compound 1 has demonstrated strong anti-cancer activity in a panel of multiple myeloma cell lines (eight of twelve were responsive, mean IC₅₀ of 0.3 nM among responsive lines). Anti-cancer activity with Compound 1 was also demonstrated in several cell line models of various Non-Hodgkin’s Lymphoma subtypes, including mantel cell lymphoma (MCL) (four of six lines tested were responsive mean IC₅₀ of 13 nM among the responsive lines), diffuse large B-cell lymphoma (DLBCL) (six of eleven germinal center B-cell like DLBCL and three of six activated B-cell DLBCL lines were responsive, with mean IC₅₀ of 12 nM and 1.6 nM respectively, amongst the responsive lines), anaplastic large cell lymphoma (ALCL) (four out of six cell lines were responsive, mean IC₅₀ of 1.7 nM among the responsive lines) and cutaneous T- cell lymphoma (CTCL) (three of four cell lines tested were responsive, mean IC₅₀ of 30 nM among the responsive lines). In mouse xenograft tumor models, Compound 1 demonstrated dose dependent efficacy from 3 μg/kg/day to 100 μg/kg/day (see Example 13). In several tumor xenografts tested daily dosing of Compound 1 at dose of 30 μg/kg/day to 100 μg/kg/day led to durable tumor regression. As shown in Figure 45A, Figure 45B, Figure 45C, Figure 52, and others Compound 1 is more than 100-fold more potent than pomalidomide in a variety of cancer assays.

In a mouse xenograft model Compound 1 has measurable plasma and tumor concentrations for longer than CC-92480 (currently in human clinical trials by Celgene, a subsidiary of Bristol Myers Squibb) despite being dosed at a 10-fold lower dose. It also takes significantly longer for IKZF3 levels to recover after treatment with Compound 1 than pomalidomide or CC-92480. For example, in an NCI-H929 tumor model it takes more than 48 hours for the IKZF3 level to reach 50% of its pretreatment level after administration of Compound 1, whereas both CC-92480 (at a x10 higher dose) and pomalidomide (at a x30 higher dose) reach pretreatment levels of IKZF3 within 48 hours of treatment.

As a result of the remarkable efficacy of Compound 1 and other compounds described herein, new advantageous treatments of disorders mediated by Ikaros (IKZF1) and/or Aiolos (IKZF3) have been discovered.

DETAILED DESCRIPTION OF THE INVENTION

The new treatments, for example low dosage regimens, described herein are based on the discovery that the described compounds are unusually highly active Ikaros and Aiolos degraders. It is thought that Compound 1 is the most potent IKZF1/3 degrader publicly disclosed to date. Data described herein and otherwise obtained establishes markedly improved antitumor effect of the combination of Compound 1 and dexamethasone. The Compounds described herein, and notably Compound 1, are significantly more efficacious than pomalidomide across NHL models, including PTCL and MCL, both in vitro and in vivo. Therefore, these compounds can be used in preference over thalidomide, lenalidomide, and pomalidomide, in NHL subtypes where classical IMiDs have demonstrated clinical activity but have not been widely adopted as standard of care (MCL, DLBCL, PTCL, etc ).

It has been discovered that the compounds described herein can be administered to treat disorders mediated by Ikaros (IKZF1) and/or Aiolos (IKZF3) in a low dosage regimen once or twice a day, optionally with a drug holiday, in highly effective treatment modalities. For example, it has been discovered that treatment can be effective for a patient using one of the compounds described herein with a dosage of not more than about 500, 450, 400, 350, 325, 300, 275, 250, 225, 200, 175, 150, 125 or even 100, 75, 50 or 25 micrograms (μg) once a day (QD) or twice a day (BID). In certain embodiments, the patient is an adult (typically a human of at least 100 pounds or more, and sometimes even 125 or 150 pounds (e.g., 70 kg or more and at least typically 18 years old or more). In an alternative embodiment, the patient is pediatric (and may be less than 100, 125 or 150 pounds and typically less than 18 years old).

In certain embodiments, the dosage includes a drug holiday. A drug holiday is a time period during which the patient is not administered the active compound. Treatment cycles, for the purposes of this disclosure are usually based on a 28 day cycle. For example, the patient may be administered the active compound or its pharmaceutically acceptable salt for 21 continuous days and not administered the chemotherapeutic for 7 days during the 28 day cycle, and then optionally the regimen is repeated once or several or more times. In certain examples, one of the compounds described herein may be administered once or twice a day for at least 13, 14 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 or 27 continuous days, and then a holiday taken until the next 28 day cycle. In some embodiments, the compound is administered once or twice a day for at least 20, 21, 22, 23 or 24 continuous days followed by a drug holiday until the end of the 28 day cycle. In yet another embodiment, the drug is administered every day without a holiday to achieve continuous dosing during the dosing regimen period, which may be 1, 2, 3, or 4 weeks, or even 1, 2, 3, 4, 5 or 6 or more continual or periodic months. In another embodiment, the use of a compound described herein eliminates the need for an off-cycle period, drug holiday, or reduction in co-administered anti -neoplastic compound concentration during treatment. In yet another embodiment, the cycle period is greater than 28 days, such as greater than 30 or 35 days, and an appropriate on-cycle and off-cycle regimen determined by the patient’s healthcare specialist.

I. Definitions

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In the specification, singular forms also include the plural unless the context clearly dictates otherwise. Although methods and materials similar or equivalent to those described herein can be used in the practice and testing of the present application, suitable methods and materials are described below. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference. The references cited herein are not admitted to be prior art to the claimed application. In the case of conflict, the present specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be limiting.

Compounds are described using standard nomenclature. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs.

In certain embodiments, of each compound described herein, the compound may be in the form of a racemate, enantiomer, mixture of enantiomers, diastereomer, mixture of diastereomers, tautomer, A-oxide, or isomer, such as a rotamer, as if each is specifically described unless specifically excluded by context.

The terms “a” and “an” do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. The term “or” means “and/or”. Recitation of ranges of values are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. The endpoints of all ranges are included within the range and independently combinable. All methods and treatments described herein can be performed in a suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of examples, or exemplary language (e.g., “such as”), is intended merely to better illustrate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed.

The present invention includes compounds described herein with at least one desired isotopic substitution of an atom, at an amount above the natural abundance of the isotope, i.e., enriched. Isotopes are atoms having the same atomic number but different mass numbers, i.e., the same number of protons but a different number of neutrons. If isotopic substitutions are used, the common replacement is at least one deuterium for hydrogen.

More generally, examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, and fluorine such as ²H, ³H, ⁿC, ¹³C, ¹⁴C, ¹⁵N, ¹⁷0, ¹⁸O, and ¹⁸F, respectively. In one non-limiting embodiment, isotopically labelled compounds can be used in metabolic studies (with, for example ¹⁴C), reaction kinetic studies (with, for example ²H or ³H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. Additionally, any hydrogen atom present in the compound of the invention may be substituted with an ¹⁸F atom, a substitution that may be particularly desirable for PET or SPECT studies. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

By way of general example and without limitation, isotopes of hydrogen, for example, deuterium (²H) and tritium (³H) may be used anywhere in described structures that achieves the desired result. Alternatively, or in addition, isotopes of carbon, e.g., ¹³C and ¹⁴C, may be used.

Isotopic substitutions, for example deuterium substitutions, can be partial or complete. Partial deuterium substitution means that at least one hydrogen is substituted with deuterium. In certain embodiments, the isotope is 90, 95 or 99% or more enriched in an isotope at any location of interest. In one non-limiting embodiment, deuterium is 90, 95 or 99% enriched at a desired location.

In one non-limiting embodiment, the substitution of a hydrogen atom for a deuterium atom can be provided in any compound described herein. For example, when any of the groups are methyl or ethyl the alkyl residue may be deuterated (in non-limiting embodiments, CDEE, CD2H, CD₃, CH2CD3, CD2CD3, CHDCH2D, CH2CD3, CHDCHD2, etc ). The compounds of the present invention may form a solvate with a solvent (including water). Therefore, in one non-limiting embodiment, the invention includes a solvated form of the compounds described herein. The term "solvate" refers to a molecular complex of a compound of the present invention (including a salt thereof) with one or more solvent molecules. Non-limiting examples of solvents are water, ethanol, isopropanol, dimethyl sulfoxide, acetone and other common organic solvents. The term "hydrate" refers to a molecular complex comprising a compound of the invention and water. Pharmaceutically acceptable solvates in accordance with the invention include those wherein the solvent may be isotopically substituted, e.g. D2O, deacetone, de-DMSO. A solvate can be in a liquid or solid form.

A “dosage form” means a unit of administration of an active agent. Examples of dosage forms include tablets, capsules, injections, suspensions, liquids, emulsions, implants, particles, spheres, creams, ointments, suppositories, inhalable forms, transdermal forms, buccal, sublingual, topical, gel, mucosal, and the like. A “dosage form” can also include an implant, for example an optical implant.

As used herein “endogenous” refers to any material from or produced inside an organism, cell, tissue or system.

As used herein, the term “exogenous” refers to any material introduced from or produced outside an organism, cell, tissue or system.

By the term “modulating,” as used herein, is meant mediating a detectable increase or decrease in the level of a response in a patient compared with the level of a response in the patient in the absence of a treatment or compound, and/or compared with the level of a response in an otherwise identical but untreated patient. The term encompasses perturbing and/or affecting a native signal or response thereby mediating a beneficial therapeutic response in a patient, preferably, a human.

“Parenteral” administration of a compound includes, e.g., subcutaneous (s.c.), intravenous (i.v.), intramuscular (i.m.), or intrasternal injection, or infusion techniques.

As used herein, “pharmaceutical compositions” is a composition comprising at least one active agent such as a selected active compound described herein, and at least one other substance, such as a carrier. “Pharmaceutical combinations” are combinations of at least two active agents which may be combined in a single dosage form or provided together in separate dosage forms with instructions that the active agents are to be used together to treat any disorder described herein. As used herein, a “pharmaceutically acceptable salt” is a derivative of the disclosed compound in which the parent compound is modified by making inorganic and organic, acid or base addition salts thereof with a biologically acceptable lack of toxicity. The salts of the present compounds can be synthesized from a parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting free acid forms of these compounds with a stoichiometric amount of the appropriate base (such as Na, Ca, Mg, or K hydroxide, carbonate, bicarbonate, or the like), or by reacting free base forms of these compounds with a stoichiometric amount of the appropriate acid. Such reactions are typically carried out in water or in an organic solvent, or in a mixture of the two. Generally, non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are typical, where practicable. Salts of the present compounds further include solvates of the compounds and of the compound salts.

Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts and the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, conventional non-toxic acid salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, mesylic, esylic, besylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, HOOC-(CH2)n- COOH where n is 0-4, and the like, or using a different acid that produces the same counterion. Lists of additional suitable salts may be found, e.g., in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., p. 1418 (1985).

The term “carrier” means a diluent, excipient, or vehicle that an active agent is used or delivered in.

A “pharmaceutically acceptable excipient” means an excipient that is useful in preparing a pharmaceutical composition/combination that is generally safe, and neither biologically nor otherwise inappropriate for administration to a host, typically a human. In certain embodiments, an excipient is used that is acceptable for veterinary use. A “patient” or “host” is a human or non-human animal in need of treatment, of any of the disorders as specifically described herein. Typically, the host is a human. A “host” may alternatively refer to for example, a mammal, primate (e.g., human), cow, sheep, goat, horse, dog, cat, rabbit, rat, mice, fish, bird and the like. A “therapeutically effective amount” of a pharmaceutical composition/combination of this invention means an amount effective, when administered to a host, to provide a therapeutic benefit such as an amelioration of symptoms or reduction or diminution of the disease itself.

In certain embodiments, a compound or its corresponding pharmaceutically salt, isotopic derivative, or prodrug as described herein can be administered in an effective amount to treat a host, for example a human, with a T-cell or NK-cell lymphoma such as, but not limited to: anaplastic lymphoma kinase (ALK) positive, ALK negative anaplastic large cell lymphoma, or primary cutaneous anaplastic large cell lymphoma; angioimmunoblastic lymphoma; cutaneous T- cell lymphoma, for example mycosis fungoides, Sezary syndrome, primary cutaneous anaplastic large cell lymphoma, primary cutaneous CD30+ T-cell lymphoproliferative disorder; primary cutaneous aggressive epiderm otropic CD8+ cytotoxic T-cell lymphoma; primary cutaneous gamma-delta T-cell lymphoma; primary cutaneous small/medium CD4+ T-cell lymphoma, and lymphomatoid papulosis; Adult T-cell Leukemia/Lymphoma (ATLL); Blastic NK-cell Lymphoma; Enteropathy-type T-cell lymphoma; Hematosplenic gamma-delta T-cell Lymphoma; Lymphoblastic Lymphoma; Nasal NK/T-cell Lymphomas; Treatment-related T-cell lymphomas; for example lymphomas that appear after solid organ or bone marrow transplantation; T-cell prolymphocytic leukemia; T-cell large granular lymphocytic leukemia; Chronic lymphoproliferative disorder of NK-cells; Aggressive NK cell leukemia; Systemic EBV+ T-cell lymphoproliferative disease of childhood (associated with chronic active EBV infection); Hydroa vacciniforme-like lymphoma; Adult T-cell leukemia/ lymphoma; Enteropathy-associated T-cell lymphoma; Hepatosplenic T-cell lymphoma; or Subcutaneous panniculitis-like T-cell lymphoma.

In certain embodiments, a compound or its corresponding pharmaceutically acceptable salt, isotopic derivative, or prodrug as described herein can be administered to treat a host, for example a human, with leukemia. For example, the host may be suffering from an acute or chronic leukemia of a lymphocytic or myelogenous origin, such as, but not limited to: Acute lymphoblastic leukemia (ALL); Acute myelogenous leukemia (AML); Chronic lymphocytic leukemia (CLL); Chronic myelogenous leukemia (CML); juvenile myelomonocytic leukemia (JMML); hairy cell leukemia (HCL); acute promyelocytic leukemia (a subtype of AML); large granular lymphocytic leukemia; or Adult T-cell chronic leukemia. In certain embodiments, the patient suffers from an acute myelogenous leukemia, for example an undifferentiated AML (M0); myeloblastic leukemia (Ml; with/without minimal cell maturation); myeloblastic leukemia (M2; with cell maturation); promyelocytic leukemia (M3 or M3 variant [M3V]); myelomonocytic leukemia (M4 orM4 variant with eosinophilia [M4E]); monocytic leukemia (M5); erythroleukemia (M6); or megakaryoblastic leukemia (M7).

There are a number of skin disorders associated with cellular hyperproliferation. Psoriasis, for example, is a benign disease of human skin generally characterized by plaques covered by thickened scales. The disease is caused by increased proliferation of epidermal cells of unknown cause. Chronic eczema is also associated with significant hyperproliferation of the epidermis. Other diseases caused by hyperproliferation of skin cells include atopic dermatitis, lichen planus, warts, pemphigus vulgaris, actinic keratosis, basal cell carcinoma and squamous cell carcinoma.

Other hyperproliferative cell disorders include blood vessel proliferation disorders, fibrotic disorders, autoimmune disorders, graft-versus-host rejection, tumors and cancers.

Blood vessel proliferative disorders include angiogenic and vasculogenic disorders. Proliferation of smooth muscle cells in the course of development of plaques in vascular tissue cause, for example, restenosis, retinopathies and atherosclerosis. Both cell migration and cell proliferation play a role in the formation of atherosclerotic lesions.

Fibrotic disorders are often due to the abnormal formation of an extracellular matrix. Examples of fibrotic disorders include hepatic cirrhosis and mesangial proliferative cell disorders. Hepatic cirrhosis is characterized by the increase in extracellular matrix constituents resulting in the formation of a hepatic scar. Hepatic cirrhosis can cause diseases such as cirrhosis of the liver. An increased extracellular matrix resulting in a hepatic scar can also be caused by viral infection such as hepatitis. Lipocytes appear to play a major role in hepatic cirrhosis.

Mesangial disorders are brought about by abnormal proliferation of mesangial cells. Mesangial hyperproliferative cell disorders include various human renal diseases, such as glomerulonephritis, diabetic nephropathy, malignant nephrosclerosis, thrombotic microangiopathy syndromes, transplant rejection, and glomerulopathies.

Another disease with a proliferative component is rheumatoid arthritis. Rheumatoid arthritis is generally considered an autoimmune disease that is thought to be associated with activity of autoreactive T cells, and to be caused by autoantibodies produced against collagen and IgE.

Other disorders that can include an abnormal cellular proliferative component include Bechet’s syndrome, acute respiratory distress syndrome (ARDS), ischemic heart disease, postdialysis syndrome, leukemia, acquired immune deficiency syndrome, vasculitis, lipid histiocytosis, septic shock and inflammation in general.

In another embodiment, a compound provided herein is useful for the treatment of primary myelofibrosis, post-polycythemia vera myelofibrosis, post-essential thrombocythemia myelofibrosis, and secondary acute myelogenous leukemia.

In certain embodiments, a compound or its pharmaceutically acceptable salt, isotopic analog, or prodrug as described herein can be administered in an effective amount to treat a host, for example a human, with a myelodysplastic syndrome (MDS) such as, but not limited to: refractory cytopenia with unilineage dysplasia, refractory anemia with ring sideroblasts (RARS), refractory anemia with ring sideroblasts - thrombocytosis (RARS-t), refractory cytopenia with multilineage dysplasia (RCMD) including RCMD with multilineage dysplasia and ring sideroblasts (RCMD-RS), Refractory amenias with excess blasts I (RAEB-I) and II (RAEB-II), 5q- syndrome, refractory cytopenia of childhood, and the like.

In certain embodiments, a compound of the present invention can provide a therapeutic effect by direct degradation of Ikaros or Aiolos which may change the transcriptional regulation of a protein downstream of Ikaros or Aiolos.

The term “neoplasia” or “cancer” is used to refer to the pathological process that results in the formation and growth of a cancerous or malignant neoplasm, i.e., abnormal tissue that grows by cellular proliferation, often more rapidly than normal and continues to grow after the stimuli that initiated the new growth cease. Malignant neoplasms show partial or complete lack of structural organization and functional coordination with the normal tissue and most invade surrounding tissues, metastasize to several sites, and are likely to recur after attempted removal and to cause the death of the patient unless adequately treated. As used herein, the term neoplasia is used to describe all cancerous disease states and embraces or encompasses the pathological process associated with malignant hematogenous, ascitic and solid tumors.

Treatment Advantages

In one aspect of the present invention a treatment described herein has one or more advantages over presently approved treatments of cancer, for example treatments of multiple myeloma or Non-Hodgkin’s Lymphoma. For example, Compound 1 or a pharmaceutically acceptable salt thereof as administered using the treatments described herein has a better outcome in one or more of the measures described below than currently approved treatments, for example thalidomide, pomalidomide or lenalidomide (see Examples 9 12 13 15-19, 26-31, and 35 demonstrating the superior efficacy of Compound 1 in multiple myeloma and Non-Hodgkin’s Lymphoma models).

In certain embodiments the advantage provided by Compound 1 over currently known treatments is a decreased propensity to develop resistance. For example, mice that had developed resistance to treatment with pomalidomide still responded rapidly to treatment with Compound 1 (see Figure 40). Additionally, when treatment was withdrawn from mice for a long enough period for their tumors to regrow and rechallenged with Compound 1 the tumors still rapidly decreased in size (see Figure 33).

In other embodiments the advantage over currently approved therapies is the ability to treat refractory tumors. For example, in mice doses of Compound 1 as low as 30 μg/kg were effective in the treatment of NCLH929 tumors that were nonresponsive to 3,000 μg/kg dosing (see Figure 33). Additionally, across a panel of cell lines Compound 1 was consistently 2-3 magnitudes more potent than pomalidomide and even demonstrated efficacy against cells that were refractory to pomalidomide (see Figure 32). This effect is also demonstrated by tracking biomarkers concentration such as caspase 3 (see Figure 31). In other embodiments the advantage over currently approved therapies is a more rapid degradation of IKZF1 and IKZF3 and thus a more rapid treatment of cancer. For example, Compound 1 degrades more IKZF1 in one hour than pomalidomide degrades in two hours when dosed at the same concentration (see Figure 29).

In certain embodiments, a treatment is provided for inducing a therapeutic response as assessed by the International Uniform Response Criteria (IURC) for Multiple Myeloma (described in Durie B. G. M; et al. “International uniform response criteria for multiple myeloma. Leukemia 2006, 10(10): 1-7) in a patient having multiple myeloma comprising administering to the patient an effective amount of a compound described herein, or a pharmaceutically acceptable salt, isotopic analog, or prodrug thereof, optionally in a pharmaceutically acceptable carrier to form a composition.

In another embodiment, a treatment is provided to achieve a stringent complete response, complete response, or very good partial response, as assessed by the IURC for Multiple Myeloma in a patient having multiple myeloma comprising administering to the patient an effective amount of a compound described herein, or a pharmaceutically acceptable salt, isotopic analog, or prodrug thereof, optionally in a pharmaceutically acceptable carrier to form a composition.

In another embodiment, a treatment is provided to achieve an increase in overall survival, progression-free survival, event-free survival, time to process, or disease-free survival in a patient having multiple myeloma comprising administering to the patient an effective amount of a compound described herein, or a pharmaceutically acceptable salt, isotopic analog, or prodrug thereof, optionally in a pharmaceutically acceptable carrier to form a composition (see Examples 21 and 22 which demonstrate a dose dependent increase in overall survival in animal models).

The advantages of Compound 1 can be further enhanced by administering an additional bioactive agent in combination therapy. For example, in mouse studies when Compound 1 was administered in a treatment regimen that included weekly dexamethasone it was far more efficacious than the same dose of Compound 1 or dexamethasone alone (see Figure 41).

Additional therapeutic agents that can be administered in combination with a compound disclosed herein can include bevacizumab, sutinib, sorafenib, 2-methoxyestradiol or 2ME2, finasunate, vatalanib, vandetanib, aflibercept, volociximab, etaracizumab (MEDL522), cilengitide, erlotinib, cetuximab, panitumumab, gefitinib, trastuzumab, dovitinib, figitumumab, atacicept, rituximab, alemtuzumab, aldesleukine, atlizumab, tocilizumab, temsirolimus, everolimus, lucatumumab, dacetuzumab, HLL1, huN901-DMl, atiprimod, natalizumab, bortezomib, carfilzomib, marizomib, tanespimycin, saquinavir mesylate, ritonavir, nelfinavir mesylate, indinavir sulfate, belinostat, panobinostat, mapatumumab, lexatumumab, dulanermin, ABT-737, oblimersen, plitidepsin, talmapimod, P276-00, enzastaurin, tipifarnib, perifosine, imatinib, dasatinib, lenalidomide, thalidomide, simvastatin, celecoxib, bazedoxifene, AZD4547, rilotumumab, oxaliplatin (Eloxatin), PD0332991, ribociclib (LEE011), amebaciclib (LY2835219), HDM201, fulvestrant (Faslodex), exemestane (Aromasin), PIM447, ruxolitinib (INC424), BGJ398, necitumumab, pemetrexed (Alimta), and ramucirumab (IMC-1121B).

In certain embodiments, the additional therapy is a monoclonal antibody (MAb). Some MAbs stimulate an immune response that destroys cancer cells. Similar to the antibodies produced naturally by B cells, these MAbs may “coat” the cancer cell surface, triggering its destruction by the immune system. For example, bevacizumab targets vascular endothelial growth factor (VEGF), a protein secreted by tumor cells and other cells in the tumor’s microenvironment that promotes the development of tumor blood vessels. When bound to bevacizumab, VEGF cannot interact with its cellular receptor, preventing the signaling that leads to the growth of new blood vessels. Similarly, cetuximab and panitumumab target the epidermal growth factor receptor (EGFR), and trastuzumab targets the human epidermal growth factor receptor 2 (HER-2). MAbs that bind to cell surface growth factor receptors prevent the targeted receptors from sending their normal growth-promoting signals.

VIII. General Synthesis

The compounds described herein can be prepared by methods known by those skilled in the art. In one non-limiting example, the disclosed compounds can be made using the schemes below.

Compounds of the present invention with stereocenters may be drawn without stereochemistry for convenience. One skilled in the art will recognize that pure or enriched enantiomers and diastereomers can be prepared by methods known in the art. Examples of methods to obtain optically active materials include at least the following: i) physical separation of crystals - a technique whereby macroscopic crystals of the individual enantiomers are manually separated. This technique can be used if crystals of the separate enantiomers exist, i.e., the material is a conglomerate, and the crystals are visually distinct; ii) simultaneous crystallization - a technique whereby the individual enantiomers are separately crystallized from a solution of the racemate, possible only if the enantiomer is a conglomerate in the solid state; iii) enzymatic resolutions - a technique whereby partial or complete separation of a racemate by virtue of differing rates of reaction for the enantiomers with an enzyme; iv) enzymatic asymmetric synthesis - a synthetic technique whereby at least one step in the synthesis uses an enzymatic reaction to obtain an enantiomerically pure or enriched synthetic precursor of the desired enantiomer; v) chemical asymmetric synthesis - a synthetic technique whereby the desired enantiomer is synthesized from an achiral precursor under conditions that produce asymmetry (i.e. chirality) in the product, which may be achieved by chiral catalysts or chiral auxiliaries; vi) diastereomer separations - a technique whereby a racemic compound is reaction with an enantiomerically pure reagent (the chiral auxiliary) that converts the individual enantiomers to diastereomers. The resulting diastereomers are then separated by chromatography or crystallization by virtue of their now more distinct structural differences the chiral auxiliary later removed to obtain the desired enantiomer; vii) first- and second-order asymmetric transformations - a technique whereby diastereomers from the racemate quickly equilibrate to yield a preponderance in solution of the diastereomer from the desired enantiomer of where preferential crystallization of the diastereomer from the desired enantiomer perturbs the equilibrium such that eventually in principle all the material is converted to the crystalline diastereomer from the desired enantiomers. The desired enantiomer is then released from the diastereomer; viii) kinetic resolutions - this technique refers to the achievement of partial or complete resolution of a racemate (or of a further resolution of a partially resolved compound) by virtue of unequal reaction rates of the enantiomers with a chiral, non-racemic reagent or catalyst under kinetic conditions; ix) enantiospecific synthesis from non-racemic precursors - a synthetic technique whereby the desired enantiomer is obtained from non-chiral starting materials and where the stereochemical integrity is not or is only minimally compromised over the course of the synthesis; x) chiral liquid chromatography - a technique whereby the enantiomers of a racemate are separated in a liquid mobile phase by virtue of their differing interactions with a stationary phase (including vial chiral HPLC). The stationary phase can be made of chiral material or the mobile phase can contain an additional chiral material to provoke the differing interactions; xi) chiral gas chromatography - a technique whereby the racemate is volatilized and enantiomers are separated by virtue of their differing interactions in the gaseous mobile phase with a column containing a fixed non-racemic chiral adsorbent phase; xii) extraction with chiral solvents - a technique whereby the enantiomers are separated by virtue of preferential dissolution of one enantiomer into a particular chiral solvent; xiii) transport across chiral membranes - a technique whereby a racemate is place in contact with a thin membrane barrier. The barrier typically separates two miscible fluids, one containing the racemate, and a driving force such as concentration or pressure differential causes preferential transport across the membrane barrier. Separation occurs as a result of the non-racemic chiral nature of the membrane that allows only one enantiomer of the racemate to pass through; xiv) simulated moving bed chromatography is used in one embodiment. A wide variety of chiral stationary phases are commercially available.

Example 8 Unique Properties of Compound 1

Biomarker assessment in MM and A LCL tumor bearing studies showed deep degradation (>75%) by Compound 1 of both IKZF1/3 with duration of 24 hours. Compound 1 was effective in MM animal models that were resistant to pomalidomide. Mice bearing RPMI-8226 human MM tumor xenografts showed no response when treated with pomalidomide (3000 μg/kg/day, clinically relevant dose) for 17 days, and once Compound 1 was administered to those animals at 100 ug/kg/day it led to rapid tumor regression.

CBI7 SC1D mice bearing established RPMI-8226 xenografts were administered pomalidomide (3000 ug/kg/day) on a daily PO regimen for 3 weeks. Pomalidomide treatment was then stopped and mice were treated with Compound 1 (100 μg/kg/day) on a daily regimen for 2 weeks. Data are expressed as mean tumor volumes ± SEM.

In a single MM tumor bearing study, Compound 1 alone attained regression; however, the combination of dexamethasone (5 mg/kg, QW) with Compound 1 (10 μg/kg/day) attained longer durability of regression compared to Compound 1 alone or dexamethasone alone.

IKZF 1/3 are not degraded in mouse cells treated with thalidomide or its IMiD® analogs because of a single amino acid difference in mouse cereblon compared to human cereblon that, causes steric hindrance and prevents recruitment of IKZF1/3. Ex vivo studies were performed in peripheral blood cells (PBMC) of mice, rats, dogs, and monkeys to identify relevant species for IND enabling- toxicity studies based on the degree of IKZF1 degradation by Compound 1. IKZF1 was not degraded in mouse or rat cells by Compound 1, thus, while rat could not be considered a pharmacologically relevant species for human risk assessment, it was chosen as the rodent species for toxicological studies because it is widely used in toxicity testing and a substantial historical toxicology database is available. Compound 1 was highly effective in degrading IKZF 1/3 in cynomolgus monkey cells but had no effect on IKZF 1/3 in dog cells. Therefore, cynomolgus monkey was chosen for non-rodent toxicological studies.

Secondary pharmacodynamic (PD) studies were conducted to evaluate off-target activity of Compound 1. Global proteomic studies from ALCL tumor xenografts isolated from mice 4 hours post a single dose of Compound 1 (100 μg/kg) demonstrated that Compound 1 is highly selective, degrading only IKZF1/3 out of >7900 proteins detected in the tissue.

Specific studies were carried out to assess the ability of Compound 1 to degrade Sal-like protein 4 (SALL4), a protein implicated in the teratogenicity induced by the IMiD ®s class of IKZF1/IKZF3 degraders. In the KELLY neuroblastoma cell line, Compound 1 promoted the degradation of SALL4 by more than 85% at 10 nM, suggesting that Compound 1 has teratogenic potential. A small number of cereblon E3 ligase modulators have been shown to promote degradation of the translation termination factor GSPT1. From a targeted cell -based assay, Compound 1 had no significant effect on G1 to S Phase Transition 1 (GSPT1) up to 10 μM.

In vitro testing for specific binding or activity of Compound 1 (100 nM) against 87 potential unintended molecular targets showed no targets inhibited >50% at 500X the free plasma exposure (C_max) associated with maximum in vivo efficacy. Viability assays performed in HepG2 liver cancer cells, devoid of IKZF 1 and IKZF3, showed no significant effect on viability with Compound 1 at concentrations up to 3.3 μM.

Example 9. Potency and Catalytic Rate of Compound 1

The potency of Compound 1 was determined using an NCI-H929 viability assay and compared to pomalidomide. NCH4929 cell viability was determined based on quantification of ATP using CellTiter-Glo® 2.0 luminescent Assay kit, which signals the presence of metabolically- active cells. Briefly, test compound was added to 384-well plates at a top concentration of 1 μM with 10 points, half log titration in duplicates. NCIH929 cells were seeded into the 384-well plates in RPMI medium containing 10% FBS and 0.05 mM 2-mercaptoethanol at a cell density of 750 cells per well. Cells treated in the absence of the test compound were the negative control and cells treated in the absence of CellTiter-Glo® 2.0 were the positive control. Cells treated with the test compounds were incubated at 37 °C with 5% CO₂ for 96 hr. CellTiter-Glo reagent was then added to the cells and Luminescence was acquired on EnVision™ Multilabel Reader (PerkinElmer, Santa Clara, CA, USA). % Viability was determined by normalizing the signal with positive and DMSO treated negative controls on the same microtiter plate. The results are shown in Figure 1 A and Table 2. As shown in Table 2, Compound 1 exhibited an IC50 of 0.071 μM. Data in Figure 1 A are expressed as the mean ± SD for 3 independent experiments each with n = 2. Curve fit and IC50 determination was performed by 4 parametric regression analysis. Data in Table 1 are the geometric mean and 95% confidence interval of IC50 values and the linear mean ± SD for Emax values determined for the indicated number of independent experiments.

Table 2. The Effect of Compound 1 on H929 Cell Viability and IKZF1 Degradation

The effect of Compound 1 on NCI-H929 IKZF1 degradation was also determined. Endogenous expression of IKZF1 in NCIH929 cells was determined by addition of N-terminal HiBiT tag to the NCIH929 cell line using CRISPR-Cas9. Briefly, test compound was added to 384-well plates at a top concentration of 1 μM with 10 points, half log titration in duplicates. NCIH929 cells expressing HiBiT-tagged IKZF1 were seeded into the 384-well plates in RPMI medium containing 10% FBS and 0.05 mM 2-mercaptoethanol at a cell density of 15000 cells per well. Cells treated in the absence of the test compound were the negative control and wells containing media only were the positive control. Following compound treatment, cells were incubated at 37 °C with 5% CO₂ for 1.5 hr. HiBiT signal was determined using Nano-Gio™ HiBiT Lytic Assay System (Promega, N3050) and luminescence was acquired on EnVision™ Multilabel Reader (PerkinElmer, Santa Clara, CA, USA). % IKZF1 remaining was determined by normalizing the signal with positive and negative controls on the same microtiter plate. The results are shown in Figure IB and Table 2. As shown in Table 2, Compound 1 exhibited an IC50 of 0.27 μM. Data in Figure IB are expressed as the mean ± SD for 2 independent experiments each with n = 2. Curve fit and IC50 determination was performed by 4 parametric regression analysis. Data in Table 1 are the geometric mean and 95% confidence interval of IC50 values and the linear mean ± SD determined for the indicated number of independent experiments.

The data in Figure 29 was produced by measuring IKZF1 degradation after addition of N- terminal HiBiT tag to the endogenously expressed IKZF1 in NCIH929 cell line using CRISPR- Cas9. Test compound was added to 384-well plates at a top concentration of 1 μM for Compound 1 and 10 μM for pomalidomide with 22 points, 2-fold titration in duplicates. NCIH929 cells expressing HiBiT-tagged IKZF1 were seeded into the 384-well plates in RPMI medium containing 10% FBS and 0.05 mM 2-mercaptoethanol at a cell density of 15000 cells per well. Cells treated in the absence of the test compound were the negative control and wells containing media only were the positive control. Following compound treatment, cells were incubated at 37 °C with 5% CO₂ for 1 or 2 hr. HiBiT signal was determined using Nano-Gio™ HiBiT Lytic Assay System (Promega, N3050) and luminescence was acquired on EnVision™ Multilabel Reader (PerkinElmer, Santa Clara, CA, USA). % IKZF1 remaining was determined by normalizing the signal with positive and negative controls on the same microtiter plate. Curve fit and IC50 determination was performed by 4 parametric regression analysis. Compound 1 induced rapid degradation of IKZF1, resulting in 50% degradation after 1 hour treatment and > 80% maximal degradation after 2 hour treatment with a DC50 of 21 μM. Pomalidomide degraded less than 25% of IKZF1 at 1 hour and Compound 1 showed potency > 2000-fold greater than pomalidomide at 2 hr.

Example 10. Compound 1 Selectivity in ALCL Tumor Xenografts Using Global Proteomics

NOD SCI mouse bearing ALCL ALK+ DL40 xenografts were treated orally with 100 μg/kg of Compound 1. After 1, 4, 24 and 48 hour treatment, biological duplicates of tumoral cells were harvested, washed twice with PBS, and snap frozen in liquid nitrogen. Samples were resuspended in lysis buffer [8 M urea, 50 mM EPPS (pH 8.5), 50 mM NaCl, lx protease inhibitor cocktail] and lysed by sonication. Lysates were centrifuged at maximum speed, reduced for 1 hour at room temperature with 5 mM TCEP, and the cysteine residues were then alkylated with 15 mM iodoacetamide (room temperature, in dark, 30 minutes). Protein content was extracted twice by methanol-chloroform precipitation and subsequent ice-cold acetone washes. Protein pellets were resuspended in 8 M urea, 50 mM EPPS (pH 8.5) buffer and protein concentrations were measured by BCA assay. Samples were then diluted to 4 M urea with 50 mM EPPS (pH 8.5) and digested at 37°C for 1 hour with endoproteinase Lys-C, at a 1/100 enzyme/protein ratio. The mixtures were then diluted to 1 M urea with 50 mM EPPS (pH 8.5) and trypsin was added at a 1/50 enzyme/protein ratio. The reaction was incubated overnight at 37°C and stopped by acidification with formic acid 0.5% (v/v). Peptides were loaded on tC18 SepPak solid-phase extraction cartridges and lyophilized.

For peptide labeling, 100 μg of peptides per sample was prepared at 1 μg/pl concentration in 200 mM EPPS (pH 8.5), ACN was added to a final concentration of 30% and then 50 μg of each TMT10 reagent. After 1 hour incubation at room temperature, reactions were quenched with 0.3% hydroxylamine for 15 minutes and mixed equally. The mixed sample was desalted using the tC18 SepPak solid-phase extraction cartridges, and lyophilized. Dried peptides were resuspended in 5% ACN, 10 mM NH4HCO3 pH 8 and fractionated in a basic pH reversed phase chromatography using a HPLC equipped with a 3.5 pm XB ridge Peptide BEH Cl 8 column. 96 fractions were collected, which were consolidated into 24, of which only 12 nonadj acent samples were analyzed. Samples were desalted, dried via vacuum centrifugation and reconstituted in 12pL of 5% formic for LC- MS/MS analysis.

A third of each sample (4 pL) was separated by reversed phase chromatography using an EASY-Spray C18 column (2 pm particle size, 250 mm length x 75 pm ID) mounted in an EASY- nLC 1200 LC pump coupled to an Orbitrap Fusion Lumos Tribid mass spectrometer. Peptides were separated using a 420 min gradient of 2 to 30% acetonitrile at a flow rate of ~ 300 nL/min. Each analysis was performed using the multi-notch MS3 (SPS-MS3) scan. For the identification and relative quantification, all RAW files obtained from the mass spectrometer were transformed using SEQUEST-based software. Briefly, mass spectra were searched against the human Uniprot database (February 2016) concatenated with a database composed of all protein sequences in the reversed order as well as known contaminants. In all SEQUEST searches, precursor ion tolerance was set at 25 ppm and product ion tolerance at 0.9 Da, including methionine oxidation (+15.9949 Da) and cysteine carbamidomethylation (+57.0215 Da) as variable modifications. TMT tag (+229.1629 Da) on lysine residues and peptide N-termini were set as static modifications. Peptide- spectrum matches (PSMs) were performed using a linear discriminant analysis and adjusted to a 2% FDR2. Peptide intensities were quantified by extracting the signal -to-noise ratio and proteins were further collapsed to a final protein-level FDR of 2%. Protein quantification values were exported to Excel, GraphPad Prism 7 or Perseusl4 for further analysis. The resulting data is shown in Figure 2 A and a 24 hour experiment is shown in Figure 2B.

The identified proteins are shown in Table 3 and Table 4 below Table 3 Identified Proteins From 4-Hour Proteomics Study

Example 11. Compound 1-induced Ikaros Degradation in Ki-JK (ALK+) cells

Flow cytometry was used to assess the Ikaros degradation characteristics and evaluate the mechanism of Compound 1. Ki-JK cells (DSMZ, ACC 695) were seeded in 96-well plates prespotted with Compound 1 in dose response (11 -point, duplicate, 0.001-100 nM), with and without bortezomib (proteasome inhibitor, 10 μM) or MLN-4924 (neddylation inhibitor, 10 μM). The cells were prepared for staining using the FOXP3 Fix/Perm Buffer Set (BioLegend, 421403) according to the manufacturer’s instructions at 1.5, 3, and 6 hours. IKZF1-AF488 (564867) and IgGl-488 (557782) (BD Biosciences) were diluted 1 : 100 in Perm Buffer. Signal was detected using the Guava® easyCyte™ Flow Cytometer. As shown in Figure 3, potent dose response degradation over time with Compound 1 was observed and the maximal degradation was observed at 6 hours. Degradation was not observed with the combination of Compound 1 and bortezomib or MLN- 4924.

Example 12. Compound 1 Anti-proliferative Activity in Hematological Cancer

The anti -proliferative activity of Compound 1 in hematological cancer cell lines was evaluated and compared to Pomalidomide. The cells were treated for 96 hours and the results are shown in Table 5. Compound 1 is more potent than pomalidomide in every cell line, and in multiple cell lines, it is more than 5,000-fold more active. Table 5.

Example 13. Compound 1 Efficacy in Multiple Myeloma

Compound 1 efficacy in two multiple myeloma cell lines (NCI-H929) and (RPMI-8226) was evaluated at four different doses: 3 μg/kg, 10 μg/kg, 30 μg/kg, and 100 μg/kg. Compound 1 was administered QD (every day) orally (PO). The efficacy of Compound 1 was compared to pomalidomide (administered at 3000 μg/kg). The results in the NCI-H929 and RPMI-8826 cells lines are shown in Figures 4 and 5, respectively. Table 6 describes the statistical significance of the experiment in each cell line for each dose. Compound 1 at all four concentrations was reduced tumor volume more than pomalidomide administered at 3000 μg/kg.

Table 6. Statistical Significance of Compound 1 Compared to Vehicle

For the NCI-H929 cells, the xenograft study was conducted in female NOD SCID mice bearing NCI-H929 multiple myeloma tumors. Female SCID mice were inoculated subcutaneously in the right flank with 5x10⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=l : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once the tumors reached a volume range of 84-267 mm³ (18 days after implantation), the animals were divided randomly into groups of 6, stratified to result in about equal average tumor sizes in each treatment group. Treatment began on Day 0 with established subcutaneous NCI-H929 tumors with a mean tumor volume (MTV) of 149-150 mm³.

All agents were administered to mice bearing NCI-H929 tumors on day 0 and dosed PO daily for 21 days, except for the vehicle group which was dosed for 18 days. Compound 1 was dosed at 3, 10, 30, or 100 μg/kg and was formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Pomalidomide was dosed at 3000 μg/kg and used the same formulation as Compound 1. Body weight and MTV were measured on a 2x weekly schedule and the study end point was a MTV of 2460 mm³ in the vehicle control group on Day 18. Statistical analysis was performed using two-way analysis of variance (ANOVA). Data are expressed as MTV ± SEM.

For the RPMI-8226 MM model, the female CB17 SCID mice were inoculated subcutaneously in the right flank with 10x10⁶ RPMI-8226 cells in 0.2 mL of PBS supplemented with matrigel (PBS:matrigel=l : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once the tumors reached a volume range of 109-158 mm³ (28 days after implantation), the animals were divided randomly into groups of 6, stratified to result in about equal average tumor sizes in each treatment group. Treatment began on Day 0 with established subcutaneous RPMI-8226 tumors with a mean tumor volume (MTV) of 130 mm³.

All agents were administered to mice bearing RPMI-8226 tumors on day 0 and dosed PO daily for 31 days. Compound 1 was dosed at 3, 10, 30, or 100 μg/kg and was formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Body weight and MTV was measured on a 2x weekly schedule and the study end point was a MTV of 2211 mm³ in the vehicle control group on Day 31. Statistical analysis was performed using two-way analysis of variance (ANOVA). Data are expressed as MTV ± SEM. Example 14. Compound 1 Demonstrates Rapid Tumor Elimination in Multiple Myeloma

Model

Compound 1 was administered at 300 μg/kg QD (every day) orally to female NOD SCID mice with disseminated MM1.S multiple myeloma tumors with a measurable MM1.S tumor burden on day 0 and dosed PO daily for 3 weeks. Compound 1 was formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Body weight and tumor burden were measured on a 2x weekly schedule and the study end point was 20 days post the dosing, day 41. Data are expressed as mean BLI ± SEM.

A xenograft study was conducted. Female SCID animals were irradiated with a 200 rads Co60 irradiator source and after 24 hours, animals were inoculated via tail vein injection with 1 x 107 MMl.S-Luc in 200μL PBS. Tumor burden was measured twice weekly using imaging analysis. Mice were injected intraperitoneally with 15 mg/mL of D-luciferin and anesthetized with 1-2% isoflurane inhalation. 10 minutes post luciferin injection, mice were imaged using IVIS Lumina II (Perkin Elmer) and total bioluminescence signal (BLI, photons/s) was measured in a region of interest (ROI). BLI from ROI were quantified and used as an indicator of tumor burden. 29 days post tumor cell inoculation mice were randomized into two groups, with 3 mice per group and an average BLI of 17x10⁶ photons. Figure 6 are images of the mice administered Compound 1 compared to the mice administered vehicle. Images were taken on days 4, 7, 11, 14, and 18. As shown in Figure 8, the total bioluminescence signal of the mice administered Compound 1 was significantly less than the mice administered vehicle. This data is also presented in Figure 34.

Example 15. Compound 1 in Pomalidomide Resistant or Refractory Myeloma Models

Compound 1 was tested in a multiple myeloma cell line resistant to pomalidomide (H929 PomR) and a refractory multiple myeloma cell line (RPMI8226). The results are shown in Figure 8 (H929 PomR cells) and Figure 9 (RPMI-8226 cells).

H929 multiple myeloma cells resistant to pomalidomide (H929 PomR) were generated by continued treatment in vitro with pomalidomide until the proliferation of cells was no longer inhibited. H929 PomR cells were implanted into NOD SCID mice subcutaneously in the right flank at a concentration of 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Mice were then treated daily with pomalidomide (5000 μg/kg/day) for 14 days until they were cohorted into groups of 8, stratified to result in about equal average tumor sizes in each treatment group.

Following a single day of drug washout, mice were administered Compound 1 (100 μg/kg/day) or pomalidomide (3000 μg/kg/day) on a daily PO regimen. Both compounds were formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Body weight and mean tumor volume (MTV) were measured on a 2x weekly schedule, and the study end point was a MTV of 1048 mm³ in the pomalidomide control group on Day 24. Data are expressed as MTV ± SEM. As shown in Figure 8, the tumors in the mice administered Compound 1 were smaller over the course of the study the mice administered pomalidomide.

Pomalidomide was dosed at 3000 μg/kg for 17 days and was formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Vehicle treated animals were treated for 28 days until tumors reached a MTV of 2211 mm³. Pomalidomide treated animals were crossed over onto Compound 1 (100 μg/kg/day) starting on day 18 and dosed for 21 additional days. Data are expressed as MTV ± SEM. As shown in Figure 9, the tumor volume began to decrease when mice were crossed over from pomalidomide to Compound 1.

Statistical analysis was performed using two-way analysis of variance (ANOVA). Data are expressed as MTV ± SEM. The data from this experiment is presented in Figure 35.

In another experiment each mouse was inoculated subcutaneously at the right flank with RPMI-8226 tumor cells (10 x 10⁶) in 0.2 mL of PBS supplemented with Matrigel (PBS: Matrigel= 1: 1) for tumor development. Tumor growth was monitored throughout the study. Tumor volume was measured in two dimensions using calipers and volume was calculated using the formula: (w2 x 1)/2= mm3, assuming 1 mg is equivalent to 1 mm3 of tumor volume. Measurements were twice weekly. The health of the mice was monitored, and noteworthy clinical observations were recorded. Acceptable toxicity was defined as a group’s mean BW loss of less than 20% during the study and not more than one treatment related death among ten treated animals, or 10%.

Once the tumors reached a volume range of 108-158 mm³ (28 days after implantation), the animals were randomized into groups of 6. Treatment began on Day 0 with established subcutaneous RPMI-8226 tumors with an MTV of 130 mm³. Animals were weighed on a twice weekly schedule. Mice were administered Compound (100 μg/kg/day) or pomalidomide (3000 μg/kg/day) on a daily PO regimen. Both compounds were formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). After 17 days of pomalidomide dosing, a single day of drug washout was performed and mice in this group were administered Compound 1 (100 μg/kg/day) starting on day 18). Body weight and mean tumor volume (MTV) were measured on a 2x weekly schedule, and the study end point was when the vehicle control reached a MTV of 2211 mm³.

Female SCID mice were inoculated subcutaneously in the right flank with 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once tumors reached a volume of 450 mm³ they were stratified into 3 treatment groups, consisting of 4 mice each.

A single dose of Vehicle, Pomalidomide (3000 μg/kg), or Compound 1 (30 or 100 μg/kg) was given to mice bearing KI-JK tumors. All compounds were formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Mice were sacrificed and tumors harvested at 6 and 24 hours post single dose. Tumors were mechanically homogenized, and protein extracted using RIPA buffer (Sigma Aldrich). Protein concentration was quantified using a Pierce™ BCA Protein Assay Kit, samples were reduced, and equal protein amounts were then loaded onto a western blot gel for analysis. Samples were analyzed for IKZF1 (Invitrogen, PA5-23728) and IRF- 4 (CST, 15106) expression. IKZF1 expression is shown in Figure 13 A and IRF-4 expression is shown in Figure 13B. Data is expressed as percentage of IKZF1 or IRF-4 in comparison to the vehicle control and normalized to GAPDH levels to control for protein loading. Error bars represent ± SEM values. As shown in Figures 13 A and 13B, the percentage of IKZF1 and IRF-4 was smaller in mice administered Compound 1 compared to mice administered pomalidomide at both the 6-hour and 24-hour timepoint.

Female SCID mice were inoculated subcutaneously in the right flank with 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once tumors reached a volume of 324 mm³ they were stratified into 3 treatment groups.

A single dose of Vehicle, Pomalidomide (3000 μg/kg), or Compound 1 (30 or 100 μg/kg) was given to mice bearing DL-40 tumors. All compounds were formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). For the vehicle control group, 3 mice were sacrificed, and tumors harvested 24 hours post dose. Mice dosed with Pomalidomide were sacrificed at 1, 4, and 24 hours post dose, with two mice sampled per timepoint. Mice in the Compound 1 groups were sampled at 1, 4, 24, and 48 hours post dose with four tumors collected per timepoint. Tumors were then mechanically homogenized, and protein extracted using RIP A buffer (Sigma Aldrich). Protein concentration was quantified using a Pierce™ BCA Protein Assay Kit, samples were reduced, and equal protein amounts were then loaded onto a western blot gel for analysis as shown in Figure 15B. Samples were analyzed for IKZF1 (Invitrogen, PA5-23728) expression as shown in Figure 15 A. Data is expressed as percentage of IKZF1 in comparison to the vehicle control and normalized to GAPDH levels to control for protein loading. Error bars represent ± SEM values.

Example 19. Compound 1 Efficacy in Mice with DL-40 Tumors

A xenograft study was conducted in female NOD SCID mice bearing DL-40 ALCL tumors. Female SCID mice were inoculated subcutaneously in the right flank with 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume.

A second xenograft study was conducted in female NOD SCID mice bearing DL-40 ALCL tumors. Female SCID mice were inoculated subcutaneously in the right flank with 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once the tumors reached a volume range of 187-335 mm³ (31 days after implantation), the animals were divided randomly into groups of 2, stratified to result in about equal average tumor sizes in each treatment group.

Example 26 Fluorescent Polarization

Compounds were dispensed from serially diluted DMSO stock in low dead volume plates into black 384-well compatible FP plates using acoustic technology to 1% of total reaction volume. Compounds were arranged vertically in rows A through P. Concentrations series were horizontal: columns 1-11, and then duplicates in columns 12-22. Columns 23 and 24 are reserved for 0% (5 nM probe) and 100% controls (protein at high concentration with 5 nM probe), respectively.

A 20 pL mixture containing 10 nM cereblon-DDB 1 and 5 nM probe dye in 50 mM HEPES, pH 7.4, 200 mM NaCl, 1 mM TCEP, 0.1% BSA and 0.05% Pluronic Acid F-127 was added to wells containing compound and incubated at room temperature for 1.5 hours. Controls wells with 100% bound probe contained 100 nM of cereblon. Matching control plates excluding cereblon-DDB 1 were used to correct for background fluorescence. Plates were read on an Envision plate reader with appropriate FP filter sets. The results from testing Compound 1 and Pomalidomide in this assay are shown in Figure 27. Example 27 In-cell Cereblon Competition

The cell permeability and binding affinity of Compound 1 and pomalidomide to cellular cereblon (CRBN) was determined by competitive displacement of a NanoBRET™ tracer reversibly bound to a cereblon-NanoLuc® fusion protein in 293T cells. 293T cells were modified by lentiviral transfection to express a fusion of cereblon and NanoLuc® luciferase. The modified cereblon- NanoLuc 293 T cell line was co-treated with varying concentrations of test compound and a probe conjugated with NanoBRET fluorescent tracer at its predetermined KD concentration (300 nM) and incubated for 2 hours at 37°C to reach equilibrium. Affinity of test compound was determined by displacement of NanoBRET tracer signal following the addition of NanoBRET reagents (Promega). 40 uL cereblon-NanoLuc 293T cells suspended in OptiMEM media at 2 x 10⁵ cells / mL (8000 cells / well) were dispensed using a Multidrop Combi Reagent Dispenser (Thermo Fisher) to each well of 384-well white TC-treated microplates (Coming 3570). 10 mM DMSO test compound stock solution was serially diluted (half log) in DMSO to generate 11 -point dose series in an acoustic ready 384-well low dead volume microplate (Labcyte). Using Echo 550 Acoustic Liquid Handler (Labcyte), 40 nL of serially diluted compound solutions were dispensed in duplicate to each 384-well white TC-treated microplate containing cereblon-NanoLuc 293T cells. 40 nL DMSO was transferred to all control wells. 40 nL NanoBRET tracer was dispensed to all wells in column 1-23 at its pre-determined KD concentration (300 nM). 40 nL additional DMSO was dispensed to column 24. Final concentration of DMSO was 0.2% for all samples. Plates were spun briefly and cells were incubated at 37°C; 5% CO₂ for 2 hr. 20 uL NanoBRET TE Assay reagents were added to each well and NanoBRET signal was acquired on an EnVision Multilabel Reader (PerkinElmer). Donor emission from cereblon-NanoLuc was detected at 450 nm with a NanoLuc 460/50 filter and Acceptor fluorescence of NanoBRET-pomalidomide tracer (618 nm) was detected with a 600 nm long pass NanoBRET filter. Ratio of Acceptor signal / Donor signal was calculated for each well. Column 24 (cells without NanoBRET-pomalidomide tracer addition) was used as positive control (P). Percent response of compound-treated samples (T) were calculated by normalizing the Acceptor/Donor ratio for each well to the DMSO treated negative (N) controls on the same microtiter plate after background (i.e. positive control) signal subtraction: Response % = 100 x (Signal(T) - Average (P)) / (Average (N) - Average (P)). The results from testing Compound 1 and pomalidomide in this assay are shown in Figure 28. Example 28 IKZF1/IKZF3 Degradation

Western blot was used to assess Aiolos (IKZF3) and Ikaros (IKZF1) degradation characteristics of Compound 1. NCI-H929 cells (ATCC, CRL-9068) were seeded in 6-well plates pre-spotted with Compound 1 or pomalidomide in dose response (5-point, 0.01 - 100 nM). After a 4-hour incubation period with compounds, the pellets were washed with PBS and frozen at - 80°C. Cell pellets were lysed in lysis buffer [RIPA (Thermo, Ref 89901), 1x Halt Protease and Phosphatase inhibitor cocktail (Thermo, Pro#1361281), benzonase (Sigma, El 014-5 JU)] for 10 minutes on ice. Insoluble proteins were cleared form the lysates by centrifugation (21.2 x g, 10 minutes).

Protein concentrations were measured using the BCA Protein Assay Kit (Thermo, 23228). Protein standard curve, prepared with BSA, and samples protein concentrations were read using the Envision Multilabel Reader (PerkinElmer). Lysate concentrations were normalized with lysis buffer and Laemmli 6X, SDS-Sample Buffer, Reducing (Boston BioProducts, Inc. Part #BP-111R- 50ml). Normalized samples and Chameleon® Duo Pre-stained Protein Ladder (LLCOR, 928- 60000) were loaded onto 4-15% Criterion™ Tris-HCl Protein Gel (Bio-Rad, #3450028). Gels ran at 120 V for 1.5 hours. Protein transfer was completed with the Trans-Blot Turbo Transfer System (Bio-Rad, 1704150EDU) at 25 V for 7 minutes using the Trans-Blot Turbo RTA Midi 0.2 pm Nitrocellulose Transfer Kit (Bio-Rad, catalog #1704271) following manufacturer recommendations.

Membranes were blocked while rocking for one hour in Intercept® Blocking Buffer (TBS) (LLCOR, catalog # 927-50000). Primary antibodies were diluted in Intercept® T20 (TBS) Protein- Free Antibody Diluent (LLCOR, catalog #927-85001) and incubated while rocking at 4°C overnight.

Membranes were washed 3 times for 5 minutes in TBS-T while rocking. Secondary antibodies were diluted in Intercept® T20 (TBS) Protein-Free Antibody Diluent (LI-COR, catalog # 927-85001) and incubated on membranes for 1 hour while rocking at room temperature. Membranes were washed as previously described and imaged on the Odyssey CLx. Data are expressed as percentage of Aiolos or Ikaros in comparison to the vehicle control and normalized to β-actin control for sample loading. The resulting western blot is shown in Figure 30.

Example 29 Apoptosis Induction Assay

Apoptosis induction in NCIH929 multiple myeloma cells was determined by measuring Caspase 3/7 activity following 72 hour treatment with Compound 1 using Caspase 3/7 Assay System (Promega, G8091). Briefly, test compound was added to white 384-well TC-treated plates at a top concentration of 100 nM for Compound 1 and 10 μM for pomalidomide with 10 points, half log titration in duplicates. 30 pL NCIH929 cells were seeded into the 384-well plates in RPMI medium containing 10% FBS and 0.05 mM 2-mercaptoethanol at a cell density of 1000 cells per well. Cells treated in the absence of the test compound were the negative control. Following compound treatment, cells were incubated at 37 °C with 5% CO₂ for 72 hr. 30 pL reconstituted Caspase 3/7 Assay detection reagent was added to each well and luminescence was acquired on EnVision™ Multilabel Reader (PerkinElmer, Santa Clara, CA, USA). Maximum caspase 3/7 activity of > 2-fold was observed following 72 hours with an EC50 = 0.58 nM for Compound 1 and 407 nM for pomalidomide. Data from this method is presented in Figure 31.

Example 30 Anti-Proliferation Activity Assay

Growth of 8 multiple myeloma cell lines was determined after 96 hour treatment with Compound 1 or pomalidomide based on quantification of ATP using CellTiter-Glo® 2.0 luminescent Assay kit, which signals the presence of metabolically active cells. Briefly, test compound was added to 384-well plates at a top concentration of 100 nM for Compound 1 and 10 μM for pomalidomide with 10 points, half log titration in duplicates. 50 uL cells suspended in growth media at cell densities indicated for each cell line in Table 14 were dispensed using a Multidrop Combi Reagent Dispenser (Thermo Fisher) to 384-well black TC-treated microplates containing duplicate concentration range of test compounds and DMSO controls. Cells treated in the absence of the test compound were the negative control and cells treated in the absence of CellTiter-Glo® 2.0 were the positive control. Cells were incubated at 37 °C with 5% CO₂ for 96 hr. CellTiter-Glo reagent was then added to the cells and luminescence was acquired on EnVision™ Multilabel Reader (PerkinElmer, Santa Clara, CA, USA). % Viability was determined by normalizing the signal with positive and DMSO treated negative controls on the same microtiter plate. Compound 1 inhibited growth for all eight multiple myeloma cell lines with maximal inhibition greater than 50% and IC50s less than 1 nM and was 1000-fold more potent that pomalidomide. The resulting data is shown in Figure 32.

Example 31. Compound 1 Efficacy in Multiple Myeloma

Compound 1 efficacy in a multiple myeloma cell line (NCI-H929) was evaluated at four different concentrations: 3 μg/kg, 10 μg/kg, 30 μg/kg, and 100 μg/kg. Compound 1 was administered QD (every day) orally (PO). The efficacy of Compound 1 was compared to pomalidomide (administered at 3000 μg/kg). The results in the NCI-H929 are shown in FIG 7. Table 15 describes the statistical significance of the experiment for each dose. Treatment with Compound 1 at all 10, 30 and 100 μg/kg resulted in a reduced tumor volume more than pomalidomide administered at 3000 μg/kg. Table 15. Statistical Significance of Compound 1 Compared to Vehicle

For the NCI-H929 cells, the xenograft study was conducted in female NOD SCID mice bearing NCI-H929 multiple myeloma tumors. Female SCID mice were inoculated subcutaneously in the right flank with 5xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=l : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume. Once the tumors reached a volume range of 84-267 mm³ (18 days after implantation), the animals were divided randomly into groups of 6, stratified to result in about equal average tumor sizes in each treatment group. Treatment began on Day 0 with established subcutaneous NCI-H929 tumors with a mean tumor volume (MTV) of 149-150 mm³.

All agents were administered to mice bearing NCI-H929 tumors on day 0 and dosed PO daily for 21 days, except for the vehicle group which was dosed for 18 days. After the dosing period, tumor growth was monitored for 45 days. Compound 1 was dosed at 3, 10, 30, or 100 μg/kg and was formulated in PEG400 (30% v/v) + 70%v/v HPMC (1% w/v) in citrate buffer (pH 5). Pomalidomide was dosed at 3000 μg/kg and used the same formulation as Compound 1. Body weight and MTV were measured on a 2x weekly schedule. After the initial 21 days of dosing, all Compound 1 groups were monitored for tumor growth. The 10 μg/kg group was removed from study on 39. The 30 μg/kg group tumors began to regrow, and PO daily dosing resumed starting on day 40 for an additional 23 days. Statistical analysis was performed using two-way analysis of variance (ANOVA). Data are expressed as MTV ± SEM. The resulting data is shown in Figure 33. Example 32 Dose Dependent IKZF3 Degradation

A xenograft study was conducted in female CB 17 SCID mice bearing RPMI-8226 multiple myeloma tumors. Female SCID mice were inoculated subcutaneously in the right flank with 10xl0⁶ tumors cells in 0.2mL of PBS supplemented with matrigel (PBS:matrigel=1 : 1). Tumor volume was measured twice weekly in two dimensions using calipers, and volume was calculated using the formula: (w2 x 1)/2= mm³, assuming 1 mg is equivalent to 1 mm³ of tumor volume.
