Phase 1 Study of CK-301 (Cosibelimab) as a Single Agent in Subjects With Advanced Cancers
August 28, 2023 updated by: Checkpoint Therapeutics, Inc.
A Phase 1, Open-label, Multicenter, Dose-escalation Study of CK-301 Administered Intravenously as a Single Agent to Subjects With Advanced Cancers
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.

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.
