CK-301 (cosibelimab) is a fully human monoclonal antibody of IgG1 subtype that directly binds to Programmed Death-Ligand 1 (PD-L1) and blocks its interactions with the Programmed Death-1 (PD-1) and B7.1 receptors. The primary objectives of this study are to assess the safety, tolerability and efficacy of CK-301 when administered intravenously as a single agent to subjects with selected recurrent or metastatic cancers.

Exclusion Criteria: * Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways. * Concurrent treatment with a non-permitted drug. * History of severe hypersensitivity reactions to other monoclonal antibodies. * Prior malignancy active within the previous 2 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix or breast, or localized prostate cancer. * Chemotherapy, radioactive, biological cancer therapy, or tyrosine kinase inhibitor (TKI) therapy, within four weeks prior to the first dose of study drug, or who has not recovered to NCI CTCAE Grade 1 or better from the AEs due to cancer therapeutics administered more than four weeks earlier. * Significant acute or chronic infections as defined in the protocol. * Active or history of interstitial lung disease (ILD), or has had a history of pneumonitis that has required oral or IV steroids. * Active or suspected autoimmune disease or a documented history of autoimmune disease. * Known current drug or alcohol abuse. * Underlying medical conditions that will make the administration of study drug hazardous or obscure the interpretation of toxicity determination or adverse events. * Use of other investigational therapy within 28 days before study drug administration. * Pregnant or breastfeeding. * Uncontrolled or significant cardiovascular disease. * Psychiatric illness or social situation that would preclude study compliance. * Receipt of live, attenuated vaccine within 28 days prior to the first dose of study drug.

brief Summary
CK-301 (cosibelimab) is a fully human monoclonal antibody of IgG1 subtype that directly binds to Programmed Death-Ligand 1 (PD-L1) and blocks its interactions with the Programmed Death-1 (PD-1) and B7.1 receptors.

detailed Description
This is a first-in-human, Phase 1, open-label, multicenter, dose-escalation study of CK-301 (cosibelimab), a fully human monoclonal IgG1 antibody targeting PD-L1. The study will consist of 3 periods: Screening (up to 28 days), Treatment (28-day cycles), and Follow-up (up to 6 months of visits with survival follow-up for select cohorts). Following the dose escalation portion of the study, additional evaluable subjects may be included in order to further characterize safety and efficacy at selected doses and/or in specific patient sub-groups.
