Description
FIELD The present disclosure generally relates to compounds useful as inhibitors of PD-1, PD-L1 or the PD-1/PD-L1 interaction. Provided herein are compounds, compositions comprising such compounds, and methods for their use. BACKGROUND Programmed death-1 (CD279) is a receptor on T cells that has been shown to suppress activating signals from the T cell receptor when bound by either of its ligands, Programmed death-ligand 1 (PD-L1, CD274, B7-H1) or PD-L2 (CD273, B7-DC). When PD-1 expressing T cells contact cells expressing its ligands, functional activities in response to antigenic stimuli, including proliferation, cytokine secretion, and cytotoxicity are reduced. PD-1/PD-Ligand interactions down regulate immune responses during resolution of an infection or tumor, or during the development of self-tolerance. Chronic antigen stimulation, such as that which occurs during tumor disease or chronic infections, results in T cells that express elevated levels of PD-1 and are dysfunctional with respect to activity towards the chronic antigen. This is termed "T cell exhaustion." B cells also display PD-l/PD-ligand suppression and "exhaustion." Blockade of the PD-1/PD-L1 ligation using antibodies to PD-L1 has been shown to restore and augment T cell activation in many systems. Patients with advanced cancer benefit from therapy with a monoclonal antibody to PD-L1. Preclinical animal models of tumors and chronic infections have shown that blockade of the PD-1/PD-L1 pathway by monoclonal antibodies can enhance the immune response and result in tumor rejection or control of infection. Antitumor immunotherapy via PD-1/PD-L1 blockade may augment therapeutic immune response to a number of histologically distinct tumors. Interference with the PD-1/PD-L1 interaction has also shown enhanced T cell activity in chronic infection systems. Chronic lymphocytic chorio meningitis virus infection of mice also exhibits improved virus clearance and restored immunity with blockade of PD-L1. Humanized mice infected with HIV-1 show enhanced protection against viremia and viral depletion of CD4+ T cells. Blockade of PD-1/PD-L1 through monoclonal antibodies to PD-L1 can restore in vitro antigen-specific functionality to T cells from HIV patients, HCV patients or HBV patients. Accordingly, agents that block PD-1, PD-L1 and/or the PD-1/PD-L1 interaction are desired. Small molecule agents that block or inhibit PD-1, PD-L1 and/or the PD-1/PD-L1 interaction are particularly desired. US 2018/008554 A1 and WO 2015/034820 A1 disclose indanyloxyphenyl and benzyloxyphenyl derivatives as PD-1/PD-L1 inhibitors. Applicants have discovered small molecule compounds that have activity as inhibitors of PD-1, PD-L1 or inhibitors of the interaction of PD-1 with PD-L1, and thus may be useful for treating patients having cancer. SUMMARY The invention provides compounds of Formula (I) or (II) or a pharmaceutically acceptable salt thereof, as defined in claims 1 to 16. Also provided are compounds of Table 1 or a pharmaceutically acceptable salt thereof, as defined in claim 17. Also provided is a pharmaceutical composition comprising the compound or pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable excipient, as defined in claim 18. Also provided is the pharmaceutical composition, further comprising at least one additional anticancer agent or therapy selected from rituxan, doxorubicin, gemcitabine, nivolumab, pembrolizumab, and ipilimumab, and at least one pharmaceutically acceptable excipient, as defined in claim 19. Also provided is the compound or pharmaceutically acceptable salt thereof, for use in treating cancer, as defined in claim 20. DETAILED DESCRIPTION Definitions As used in the present disclosure, the following words and phrases are generally intended to have the meanings as set forth below unless expressly indicated otherwise or the context in which they are used indicates otherwise. The following description sets forth exemplary methods, parameters and the like.
