Description

METHODS AND COMPOSITIONS FOR TREATING CANCER

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No.62/174,430 filed June 11, 2015; U.S. Provisional Application No.62/174,424 filed June 11, 2015; U.S. Provisional Application No.62/188,413 filed July 2, 2015; and U.S. Provisional Application No.62/195,750 filed July 22, 2015; the entirety of which are incorporated by reference herein. BACKGROUND

[0002] Immuno-oncology focuses on the development and delivery of therapies that improve a body’s intrinsic potential for generating an effective immune response against cancer. Immuno-oncology therapies often target the immune system and not the cancer, providing the potential to treat cancer across a variety of tumor types. Manipulation of T-cell modulation is one method of augmenting the immune system to treat cancer. SUMMARY OF THE INVENTION

[0003] The immune system has an intrinsic potential for recognizing and eliminating tumor cells.

However, tumors can adapt and circumvent the immune system by disrupting T-cell checkpoint pathways. An approach to disrupt tumor inhibition of the immune system involves the targeted block of checkpoint pathways. Immune checkpoint pathway targets for activating therapeutic antitumor immunity include programmed cell death protein (PD-1) and its ligand PD-L1, indoleamine 2, 3-dioxygenase (IDO), and cytotoxic T-lymphocyte antigen 4 (CTLA-4). IDO is a heme-containing enzyme that catalyzes the oxidation of L-tryptophan to N-formyl-L-kynurenine. Another heme-containing enzyme that also catalyzes tryptophan degradation is tryptophan 2, 3-dioxygenase (TDO). TDO has been found to be expressed in many tumors and this expression prevents tumor rejection by locally depleting tryptophan. Development of TDO inhibitors for the treatment of tumors is an active area of drug development. As the active sites of both IDO and TDO enzymes are structurally similar, various inhibitors of TDO and IDO have activity against one another. Provided in this disclosure are compounds and compositions comprising TDO inhibitors, IDO inhibitors, and inhibitors of both TDO and IDO for active stimulation of the immune system. In various aspects, provided are TDO inhibitors, IDO inhibitors, and inhibitors of both TDO and IDO that are useful for the treatment of cancer.

DETAILED DESCRIPTION OF THE INVENTION

[0078] Immunotherapeutic approaches for treating cancer often comprise the manipulation of the immune system’s T-cell response by disrupting mechanisms by which tumor cells evade the immune system. One method of reducing tumor cell evasion involves the use of immune checkpoint inhibitors to potentiate the antitumor T-cell response. An exemplary immune checkpoint inhibitor for the treatment of cancer is indoleamine 2, 3-dioxygenase (IDO). The enzymatic activity of IDO is similar to that of tryptophan 2, 3-dioxygenase (TDO) and studies have implicated TDO in the development of cancer in a similar manner to IDO. Disclosed herein, in various aspects, are compositions comprising TDO and/or IDO inhibitors and optionally one or more additional agents, such as one or more additional immune checkpoint inhibitors, useful for the treatment of cancer. In various aspects, a TDO inhibitor is provided that also functions as an inhibitor of IDO, and vice versa. In some embodiments, the TDO and/or IDO inhibitor compositions provided herein are useful for the treatment of non-cancerous diseases or conditions, for example, infectious diseases. In some embodiments, the TDO and/or IDO inhibitors provided herein are useful in immunotherapy, stem cell therapy, and/or CAR T-cell therapy.

Reference to a CTLA-4 inhibitor herein includes both pharmaceutically acceptable salts and solvates of the CTLA-4 inhibitor. Reference to a TDO/IDO inhibitor herein includes both pharmaceutically acceptable salts and solvates of the TDO/IDO inhibitor. Reference to a TDO inhibitor herein includes both pharmaceutically acceptable salts and solvates of the TDO inhibitor. In some embodiments, pharmaceutically acceptable refers a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the agent, and is relatively nontoxic, i.e., the material is administered to a subject without causing undesirable biological effects or interacting in a deleterious manner with any of the agents of the composition in which it is contained.

[00217] In some embodiments, a pharmaceutically acceptable salt refers to a form of a therapeutically active agent that consists of a cationic form of the therapeutically active agent in combination with a suitable anion, or in alternative embodiments, an anionic form of the therapeutically active agent in combination with a suitable cation. In some embodiments, pharmaceutically acceptable salts are obtained by reacting an active agent (e.g., TDO/IDO inhibitor) with an acid. In some embodiments, the active agent is basic and is reacted with an organic acid or an inorganic acid. In some embodiments, an active agent is prepared as a chloride salt, sulfate salt, bromide salt, mesylate salt, maleate salt, citrate salt or phosphate salt. In some embodiments, an active agent is prepared as a hydrochloride salt. In some embodiments, pharmaceutically acceptable salts are obtained by reacting an active agent with a base. In some embodiments, the active agent is acidic and is reacted with a base. In some embodiments, the active agent is prepared as a sodium salt, calcium salt, potassium salt, magnesium salt, meglumine salt, N-methylglucamine salt or ammonium salt. In some embodiments, the compounds provided herein are prepared as a sodium salt.

[00218] In some embodiments, compositions described herein comprise one or more active agents that are prepared as prodrugs. A prodrug refers to an agent that is converted into the parent drug in vivo. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound. In some aspects, provided are compositions comprising a prodrug formulation of a CTLA-4 inhibitor described herein. In some aspects, provided are compositions comprising a prodrug formulation of an IDO inhibitor described herein. In some aspects, provided are compositions comprising a prodrug formulation of a PD-1 inhibitor described herein. In some aspects, provided are compositions comprising a prodrug formulation of a TDO/IDO inhibitor described herein. In some aspects, provided are compositions comprising a prodrug formulation of a TDO inhibitor described herein. In additional embodiments, provided are compositions comprising a prodrug formulation of a TDO/IDO inhibitor described herein and at least one additional active agent, for example, a PD-1 inhibitor, IDO inhibitor, TDO inhibitor, and/or CTLA-4 inhibitor. In additional embodiments, provided are compositions comprising a prodrug formulation of a TDO/IDO inhibitor described herein and a prodrug formulation of an active agent, for example, a PD-1 inhibitor, IDO inhibitor, TDO inhibitor, and/or CTLA-4 inhibitor. In additional embodiments, provided are compositions comprising a TDO/IDO inhibitor described herein and a prodrug formulation of an active agent, for example, a PD-1 inhibitor, IDO inhibitor, TDO inhibitor, and/or CTLA-4 inhibitor. In additional or further embodiments, the PD-1 inhibitor, IDO inhibitor, TDO/IDO inhibitor, TDO inhibitor, and/or CTLA-4 inhibitor is metabolized upon administration to a subject to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect. In some embodiments, a metabolite of an active agent is a derivative of that compound that is formed when the compound is metabolized. The term active metabolite refers to a biologically active derivative of a compound that is formed when the compound is metabolized. In some cases, a prodrug is easier to administer than the parent drug, for example, the prodrug is bioavailable by oral administration whereas the parent is not. In some cases, the prodrug has improved solubility in pharmaceutical compositions over the parent drug. In a non-limiting example, a prodrug of an active agent described herein is administered as an ester prodrug to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility, where the prodrug is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. As a further non-liming example, a prodrug is a short peptide bonded to an acid group, where the peptide is metabolized to reveal the active moiety. In some embodiments, a prodrug is designed to alter the metabolic stability and/or the transport characteristics of an active agent, to mask side effects and/or toxicity, to improve the flavor of an agent, and/or to alter other characteristics or properties of the active. In some embodiments, some of the herein-described compounds are prodrugs for other derivatives or active compounds. In some embodiments, some of the herein-described compounds are formulated as prodrugs.

[00219]A therapeutically effective amount of an agent or composition is generally the amount of an agent or composition that is required to relieve to some extent one or more symptoms of a disease being treated (e.g., cancer) and/or the amount that will prevent, to some extent, one or more symptoms of a disease that the host being treated has or is at risk of developing. The terms effective amount or therapeutically effective amount, as used herein, refer to a sufficient amount of an agent or a compound being administered, which will relieve to some extent one or more of the symptoms of the disease or condition being treated.

EXAMPLES [00275] The following examples are set forth to illustrate more clearly the principle and practice of embodiments disclosed herein to those skilled in the art and are not to be construed as limiting the scope of any claimed embodiments.

Example 1: Computational assessment of IDO/TDO inhibitors

[00276] Potential IDO/TDO inhibitors were assessed using a computational ligand-based screen. The potential IDO/TDO inhibitors were compared for structural similarity to a database of known IDO and TDO inhibitors. Conformational flexibility of the potential inhibitors was first evaluated, and representative conformers for each compound were generated. Subsequently, each conformer of each compound was evaluated for structural and chemical similarity to each of the known inhibitors. After scoring, the potential IDO/TDO inhibitors in the top 1% of all potential IDO/TDO inhibitors screened were compiled into Table 1. Example 2: In vitro assayfor TDO/IDO inhibition

[00277] Inhibition of IDO by TDO/IDO test inhibitors was assessed in vitro. A substrate mixture was prepared by mixing equal volumes of 80 mM ascorbic acid diluted in 0.405 M Tris, pH 8.0 and a mixture of 800 uL L-tryptophan, 9,000 units/mL catalase and 40 uM methyene blue. Recombinant TDO or IDO was diluted to 16 ng/uL and 50 uL loaded into wells of a 96-well plate. The reaction was started by the addition of 50 uL substrate mixture. The plate was read in kinetic mode at 321 nm for 5 minutes. The rate of increase of absorbance measured in the absence of a TDO/IDO inhibitor is taken as the maximum rate of enzymatic activity. Active TDO/IDO inhibitors decrease the rate of increased absorbance over time, indicating a reduced rate of conversion of tryptophan to N-formyl-kynurenine in a dose-dependent manner. Table 4 shows the inhibition of TDO and IDO with various TDO/IDO test compounds.

Table 4. Inhibition of TDO and IDO with TDO/IDO test compounds.

Example 3: In vitro assayfor cancer cell cytotoxicity

[00278] TDO/IDO test compounds were incubated with various cancer cell lines to determine the effect of the test compounds on cancer cell death. The CellTiter-Glo Luminescent Cell Viability Assay was used to determine cell cytotoxicity by determining the number of viable cells in culture based on quantitation of ATP, which signals the presence of metabolically active cells. INCBO24360 and Cisplatin were used as control anti-cancer agents. The IC₅₀ values corresponding to each test compound and cell line are shown in Table 5.

Table 5. Cancer cell cytotoxicity with TDO/IDO test compounds.

Example 4: In vitro assayfor IDO inhibition via cell based enzymatic assay

[00279] Inhibition of IDO by a TDO/IDO inhibitor described herein is assessed in vitro by a cell based assay. HeLa cells are routinely maintained in minimum essential media with supplements. HeLa cells are seeded in a 96-well plate at a density of 5 x 10³ and grown overnight. On the following day, human IFNy at 50 ng/mL final concentration and serial dilutions of TDO/IDO inhibitor in a total volume of 200 uL culture medium per well are added to the cells. The plates are incubated for 48 hours and then 140 uL of supernatant per well is transferred to a new 96-well plate. To hydrolyze N-formyl-kynurenine produced by IDO to kynurenine, 10 uL of 6.1 N TCA is mixed into each well with incubation at 50 °C for 30 min. The reaction mixture is centrifuged to remove sediments. Supernatant from each well are transferred to a clean 96-well plate and mixed with equal volumes of 2% (w/v) p-dimethylaminobenzaldehyde in acetic acid. Absorbance from kynurenine is measured at 480 nm. L-Kynurenine is used as a standard and is prepared in a series of concentrations (240, 120, 60, 30, 15, 7.5, 3.75,1.87 µM) in HeLa cell culture media and analyzed in the same procedure. The percent inhibition at individual concentrations is determined. The data is processed using nonlinear regression to generate IC50 values. The rate of increase of absorbance measured in the absence of a TDO/IDO inhibitor is taken as the maximum rate of enzymatic activity. Active inhibitors decrease the rate of increased absorbance over time in a dose-dependent manner, indicating a reduced rate of conversion of tryptophan to N-formyl-kynurenine.

Example 5: Murine colon cancer in vitro assay

[00280] TDO/IDO inhibitor test compounds were tested in co-culture experiments in which CT26 murine colon cancer cells and murine immune cells were seeded together. The experimental conditions were selected to reflect the tumor microenvironment, in which cancer cells and immune cells exist in dynamic interaction. Because immune cell suppression by cancer cells can act through the TDO/IDO pathway, the experiment was designed to determine if TDO/IDO test compounds could reverse the immune suppression, encourage cancer cell killing, either directly or indirectly, and activate immune cells. The following compound effects were assessed: (1) cancer cell killing, (2) CD4 cell survival and activation, by looking at the expression of activation markers CD69+ and CD71+, and (3) CD8 cell survival and activation, by looking at the expression of activation markers CD69+ and CD71+.

[00281] CT26 cell death

[00282] CT26 cell line was maintained in culture as per standard cell culture procedures. Single cell suspension of splenocytes were Balb/c (H2d) mice were prepared; RBCs were lysed using distilled water and 10XPBS and resuspended in complete RPMI medium supplemented with fetal bovine serum, supplements and 2-mercaptoethanol. CT26 cells were harvested using Trypsin/EDTA, first treated with 50 mg/ml Mitomycin C for 20 min at 37°C, washed 3 times in complete medium and then stained with 1 mg/ml of CFSE for one hour at 37°C. TDO/IDO test compounds (tioconazole, niclosamide, eltrombopag, deferasirox, sulconazole, cloconazole, miconazole) were added to final concentrations of 0, 0.1, 1.0 ,10.0, 25.0 and 50.0 mM in triplicates in 96 well round-bottom plates.1-methyl tryptophan (1MT) was used as a control compound. Effector and target cells were seeded at a 50:1 E:T ratio. Plates were incubated for 96 h at 37°C.1 ml of PI (400 mg/ml) was added to each of the wells and transferred to FACS tubes. Samples were analyzed by FACS on BDFACScan. The frequencies of non-viable target cells (CFSE+PI+) and viable target cells (CFSE+PI-) cells were measured and cell killing reported as the frequency of viable target cells as percentage of total target cell, as shown in FIG.1, panel A and panel B.

[00283] Effector cell activation

[00284] CT26 cell line was maintained in culture as per standard cell culture procedures. Single cell suspension of splenocytes were Balb/c (H2d) mice were prepared; RBCs were lysed using distilled water and 10XPBS and resuspended in complete RPMI medium supplemented with fetal bovine serum, supplements and 2-mercaptoethanol. CT26 cells were harvested using Trypsin/EDTA, treated with 50 mg/ml Mitomycin C for 20 min at 37°C, washed 3 times in complete medium and added to effector cells. TDO/IDO test compounds (tioconazole, niclosamide, eltrombopag, deferasirox, sulconazole, cloconazole, miconazole) were added to final concentrations of 0, 0.1, 1.0 ,10.0, 25.0 and 50.0 mM in triplicates in 96 well round-bottom plates.1-methyl tryptophan was used as a control compound. Effector and target cells were seeded at a 50:1 E:T ratio. Plates were incubated for 96 hrs at 37°C. Cells were harvested into FACS tubes, stained with markers (CD71, CD69, CD4, CD8) and analyzed by FACS on BDFACScan using CellQuest Analysis Software. Data are represented as % of Live cells (based on FSC/SCC gating) for effector cell (CD4, CD8) distribution. Live CD4/CD8 cells were analyzed for activation marker (CD69, CD expression), as shown in panels A and B of FIGS.2-7.

Example 6: Mouse tumor model to evaluate in vivo activity of IDO inhibitors

[00285] In vivo activity of TDO/IDO inhibitors described herein is assessed via a mouse tumor model.

[00286] Eight week old female C57BL/6 mice are inoculated subcutaneously with 1 x 10⁶ B16-GMCSF tumor cells. Tumor sizes are measured twice weekly in two dimensions using a caliper, and the volume presented in mm³ using the formula: V = 0.5(A x B2), where A and B are the long and short diameters of the tumor, respectively. Tumor bearing animals are sorted into groups with mean tumor volumes of 110-125 mm³. Each day of the study, TDO/IDO inhibitors are reconstituted in 5% DMA, 47.5% propylene glycol. Body weights are monitored throughout the study as a gross measure of toxicity and morbidity. Tumor growth control, expressed in %, is calculated using the formula: 1-[(treated (day X)– treated (day

Y))/(vehicle (day X)– vehicle (day Y)], where X is the day of last or interim measurement and Y is the day when dosing commenced.

[00287] The average size of tumors in mice untreated with TDO/IDO inhibitors is a positive control. Active IDO inhibitors lead to a decrease in tumor size as compared to the positive control.
