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.
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.

melanoma not amenable to local therapy (excluding uveal or ocular melanoma).
- For MCC: Histologically confirmed diagnosis of metastatic Merkel cell carcinoma not
amenable to local therapy.
- For RCC: Histologically confirmed diagnosis of renal cell carcinoma (with clear cell
component) with advanced or metastatic disease that is not amenable to cure by surgery
or other means.
- For UC: Histologically or cytologically documented locally advanced or metastatic
transitional cell carcinoma of the urothelium (including renal pelvis, ureters,
urinary bladder, urethra) not amenable to cure by surgery or other means.
- For HL: Histologically confirmed primary diagnosis of classical Hodgkin's lymphoma.
- For B-cell NHL: Histologically confirmed diagnosis of non-Hodgkin lymphoma.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 at trial entry
and an estimated life expectancy of at least 3 months
- Must have at least one measurable lesion based on RECIST 1.1.
- Have provided a formalin fixed tumor tissue sample from a biopsy of a tumor lesion
either at the time of or after the diagnosis of metastatic disease has been made AND
from a site not previously irradiated.
- Adequate hematological, hepatic and renal function as defined in the protocol.
- Effective contraception for both male and female subjects if the risk of conception
exists.
- Other protocol defined inclusion criteria could apply.
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.
