COMPOSITIONS FOR INHIBITING CHECKPOINT GENE EXPRESSION AND USES

THEREOF

BACKGROUND OF THE INVENTION

Related Applications

[0001] This application claims the benefit of U.S. provisional patent application serial number 62/126,368, filed on February 27, 2015, the contents of which are incorporated herein by reference in its entirety. Field of the invention

[0002] The present invention relates to compounds, compositions, and methods of use for the inhibition of checkpoint gene expression or for diagnosing, treating and/or preventing diseases and/or conditions that respond to the inhibition of checkpoint gene expression. Summary of the related art

[0003] The immune system is a hosts defense against foreign antigens; however, in order to function properly a variety of checks and balances are required to protect against self-antigens (i.e., autoimmunity) and, at the same time, provide an appropriate response against foreign. Immune-activating and immune-suppressive receptors and ligands provide these regulatory checks and balances (see Pardoll et al, The blockade of immune checkpoints in cancer immunotherapy, Nat. Rev. Cane. 12, 252 (2012)).

[0004] Immune checkpoints refer to a group of endogenous immune-suppressive ligands and receptors that are crucial for the maintenance of self-tolerance and the protection of tissues from damage when the immune system is responding to an infection, (see Y.L. Wu, et al, Immunotherapies: The Blockade of Inhibitory Signals, Int. J. Biol. Sci. 8, 1420 (2012)) In response to the induction of an immune response expression of checkpoints increases. These checkpoints act as regulatory feedback to maintain immune homeostasis.

[0005] In patients with cancer, tumor mutations give rise to tumor-specific antigens that can be recognized by the immune system, particularly T-cells, leading to elimination of cancer cells. However, to defend themselves, tumor cells can co-opt immune checkpoint pathways to suppress the immune response in the tumor microenvironment and evade the host immune system by inhibiting T cells that might otherwise attack the tumor cells, (see J.F. Grosso & M.N. Jure-Kunkel; CTLA-4 blockade in tumor models: an overview of preclinical and translational research, Cancer Immun. 13, 5 (2013); M.E. Turnis, et al; Combinatorial immunotherapy: PD-1 may not be LAG-ing behind any more, Oncolmmunology 1, 1172 (2012)).

[0006] Many previous cancer immunotherapies have likely been limited by these suppressive mechanisms. Thus there is a need to over these immunosuppressive

mechanisms in order to enhance antitumor immunotherapy applications.

[00116] In some embodiments, the small molecule linker is glycerol or a glycerol homolog of the formula HO-(CH2)₀-CH(OH)-(CH2)_i.-OH, wherein o and p independently are integers from 1 to about 6, from 1 to about 4 or from 1 to about 3. In some other embodiments, the small molecule linker is a derivative of l,3-diamino-2-hydroxypropane. Some such derivatives have the formula

[00117] In certain embodiments, the two or more oligonucleotides of the gene silencing compounds of the invention can be linked as shown in Table 2.

Domain A Domain B

Formula II 3' 5' 1 5' 3'

Formula III

Formula IV

Formula V

[00118] In certain embodiments of Formulas II and/or V, L is a linker or a nucleotide linkage and Domain A and/or Domain B are antisense oligonucleotides that are designed to selectively hybridize to the same target RNA sequence or different target RNA sequences.

[00119] In certain embodiments of Formulas II, III, IV or V, L is a linker and Domain

A and/or Domain B and/or Domain C and/or Domain D are antisense oligonucleotides that are designed to selectively hybridize to the same target RNA sequence or different target RNA sequences. For example, in one embodiment, Domain A and/or Domain B and/or Domain C of Formulas II and/or III are antisense oligonucleotides that are designed to selectively hybridize to the same target RNA sequence. In this embodiment, Domain A and/or Domain B and/or Domain C can be designed to hybridize to the same region on the target RNA sequence or to different regions of the same target RNA sequence.

[00120] In a further embodiment of this aspect of the invention, Domain A, Domain B,

Domain C, and Domain D are independently RNA or DNA-based oligonucleotides. In certain aspects of this embodiment, the oligonucleotides comprise mixed backbone oligonucleotides. [00121] In another embodiment, one or more of Domain A and/or Domain B and/or

Domain C and/or Domain D is an antisense oligonucleotide that is designed to selectively hybridize to one target RNA sequence and one or more of the remaining Domain A and/or Domain B and/or Domain C and/or Domain D is an antisense oligonucleotide that is designed to selectively hybridized to a different target RNA sequence.

[00122] In another embodiment, one or more of Domain A and/or Domain B and/or

Domain C and/or Domain D is an RNA-based oligonucleotide hybridized to a complimentary RNA-based oligonucleotide such that the domain comprises an siRNA molecule.

[00123] These gene silencing compounds of the invention can be prepared by the art recognized methods such as phosphoramidate or H-phosphonate chemistry which can be carried out manually or by an automated synthesizer. The synthetic antisense

oligonucleotides of the invention may also be modified in a number of ways without compromising their ability to hybridize to mRNA. Such modifications may include at least one intemucleotide linkage of the oligonucleotide being an alkylphosphonate,

phosphorothioate, phosphorodithioate, methylphosphonate, phosphate ester,

alkylphosphonothioate, phosphoramidate, carbamate, carbonate, phosphate hydroxyl, acetamidate or carboxymethyl ester or a combination of these and other intemucleotide linkages between the 5' end of one nucleotide and the 3' end of another nucleotide in which the 5' nucleotide phosphodiester linkage has been replaced with any number of chemical groups.

[00124] The synthetic antisense oligonucleotides of the invention may comprise combinations of intemucleotide linkages. For example, U.S. Pat. No. 5,149,797 describes traditional chimeric oligonucleotides having a phosphorothioate core region interposed between methylphosphonate or phosphoramidate flanking regions. Additionally, U.S. Pat. No. 5,652,356 discloses "inverted" chimeric oligonucleotides comprising one or more nonionic oligonucleotide region (e.g. alkylphosphonate and/or phosphoramidate and/or phosphotriester internucleoside linkage) flanked by one or more region of oligonucleotide phosphorothioate. Various synthetic antisense oligonucleotides with modified

intemucleotide linkages can be prepared according to standard methods. In certain embodiments, the phosphorothioate linkages may be mixed Rp and Sp enantiomers, or they may be made stereoregular or substantially stereoregular in either Rp or Sp form.

[00125] Other modifications of gene silencing compounds of the invention include those that are internal or at the end(s) of the oligonucleotide molecule and include additions to the molecule of the intemucleoside phosphate linkages, such as cholesterol, cholesteryl, or diamine compounds with varying numbers of carbon residues between the amino groups and terminal ribose, deoxyribose and phosphate modifications which cleave, or crosslink to the opposite chains or to associated enzymes or other proteins which bind to the genome.

Examples of such modified oligonucleotides include oligonucleotides with a modified base and/or sugar such as 2'-0,4'-C-methylene-b-D-ribofuranosyl, or arabinose instead of ribose, or a 3', 5 '-substituted oligonucleotide having a sugar which, at both its 3' and 5' positions, is attached to a chemical group other than a hydroxyl group (at its 3' position) and other than a phosphate group (at its 5' position).

[00126] Other examples of modifications to sugars of the oligonucleoti de-based compounds of the invention include modifications to the 2' position of the ribose moiety which include but are not limited to 2'-0-substituted with an -O-alkyl group containing 1-6 saturated or unsaturated carbon atoms, or with an -O-aryl, or -O-allyl group having 2-6 carbon atoms wherein such -O-alkyl, -O-aryl or -O-allyl group may be unsubstituted or may be substituted, for example with halo, hydroxyl, trifiuoromethyl, cyano, nitro, acyl, acyloxy, alkoxy, carboxy, carbalkoxyl or amino groups. None of these substitutions are intended to exclude the presence of other residues having native 2'-hydroxyl group in the case of ribose or 2' H- in the case of deoxyribose.

[00127] The gene silencing compounds according to the invention can comprise one or more ribonucleotides. For example, US Pat No. 5,652,355 discloses traditional hybrid oligonucleotides having regions of 2 '-0 -substituted ribonucleotides flanking a DNA core region. U.S. Pat. No. 5,652,356 discloses an "inverted" hybrid oligonucleotide that includes an oligonucleotide comprising a 2'-0-substituted (or 2' OH, unsubstituted) RNA region which is in between two oligodeoxyribonucleotide regions, a structure that "inverted relative to the "traditional" hybrid oligonucleotides. Non-limiting examples of particularly useful oligonucleotides of the invention have 2'-0-alkylated ribonucleotides at their 3', 5', or 3' and 5' termini, with at least four, and in some exemplary embodiments five, contiguous nucleotides being so modified. Non-limiting examples of 2'-0-alkylated groups include 2'- O-methyl, 2'-0-ethyl, 2'-0-propyl, 2'-0-butyls and 2'-0-methoxy-ethyl.

[00128] The oligonucleotide-based compounds of the invention may conveniently be synthesized using an automated synthesizer and phosphoramidite approach further described in Example 1. In some embodiments, the oligonucleotide-based compounds of the invention are synthesized by a linear synthesis approach. [00129] An alternative mode of synthesis is "parallel synthesis", in which synthesis proceeds outward from a central linker moiety. A solid support attached linker can be used for parallel synthesis, as is described in U. S. Patent No. 5,912,332. Alternatively, a universal solid support (such as phosphate attached controlled pore glass) support can be used.

[00130] Parallel synthesis of the oligonucleotide-based compounds of the invention has several advantages over linear synthesis: (1) parallel synthesis permits the incorporation of identical monomeric units; (2) unlike in linear synthesis, both (or all) the monomeric units are synthesized at the same time, thereby the number of synthetic steps and the time required for the synthesis is the same as that of a monomeric unit; and (3) the reduction in synthetic steps improves purity and yield of the final immune modulatory oligoribonucleotide product.

[00131] At the end of the synthesis by either linear synthesis or parallel synthesis protocols, the oligonucleotide-based compounds of the invention may conveniently be deprotected with concentrated ammonia solution or as recommended by the phosphoramidite supplier, if a modified nucleoside is incorporated. The product oligonucleotide-based compounds is preferably purified by reversed phase HPLC, detritylated, desalted and dialyzed.

[00132] In certain embodiments, the oligonucleotides of the gene silencing compound according to the invention are selected from the non-limiting list of the oligonucleotides shown in Table 3 below. The oligonucleotides shown in Table 3 have phosphorothioate (PS) linkages, but may also include phosphodiester linkages. Those skilled in the art will recognize, however, that other linkages, based on phosphodiester or non-phosphodiester moieties may be included.

For 3GA compounds numbers 55 through 386 listed in Table 4B, glycerol is the non- nucleotidic linker. Flow cytometric analysis

[00190] Whole blood samples with anticoagulant EDTA from mice in study were stained for 30 minutes in the dark at room temperature with the following labeled antibodies from BD Biosciences in the presence of mouse Fc blocker (Affymetrix eBioscience, 14- 0161): rat anti-mouse CD3-Alexa Fluor 647 (557869), rat anti-mouse CD4-Alexa Fluor 647 (557681), rat anti-mouse CD8-Alexa Fluor 488 (557668) or the corresponding isotype controls. Red blood cells were lysed with freshly prepared lx RBC lysis buffer (eBioscience, 00-4300) and washed with flow cytometry staining buffer (BD Biosciences, 554657).

Resuspended cell suspensions in the flow cytometry staining buffer were run on BD Accuri C6 to acquire data and analyzed by FLOWJO (TreeStar).

IC50 Analysis

[00191] Hepa 1-6 cells are co-transfected with 3GA and target plasmid simultaneously using LIPOFECTAMINE® 2000 on day one (20,000 c/well). Concentration of 3GAs were ranging from 0.019 to 41.7 nM with a 3-fold increment. RLuc siRNA was used as the positive control and 3GA mu/hu universal control was used as the negative control. On day two (24 hours post-transfection), luminescence measurements for both reporter genes are taken separately: Firefly luciferase: expression serves as the normalizer for the assay; Renilla luciferase: substrate includes a "stop" reagent to quench luminescence from firefly. Separate luminescence measurements are taken to correspond to renilla-target transcript expression. Substrate includes DTT to lyse cells. IC50 of 3GAs was calculated using GraphPad Prism 6. Results are shown in Table 5.

In Vivo Mouse Tumor Model

[00192] Colon tumor can be implanted in BALB/c mice by subcutaneous injection of

10⁶ CT26.WT cells at right flank (Tumor 1) and 10⁶ CT26.CL25 cells at left flank (Tumor 2) on day 0. Treatment can be initiated on day 6 or when tumor size reached to 70 to 80 mm³ by intra-tumor injection of gene silencing compound according to the invention at various dosages (e.g., 2 mg/kg, 5 mg/kg, 12.5 mg/kg, or 25 mg/kg) on day 6, 10, 13, 16, 20, and 22.

[00193] Tumor growth can be monitored twice per week throughout the study period.

The study can be terminated with blood, spleen and tumor tissues collected for further evaluation. T lymphocyte population in blood and spleen samples were detected and analyzed by flow cytometry. Spleen IFN-y-producing cells were detected with ELISPOT assay after culture of spleen cells for 24 hours with tumor antigen beta-gal or AH1 peptide. Tumor tissues were analyzed for gene expression by RT-PCR. EQUIVALENTS
