Brief Summary:
This is an open-label, multicenter, first-in-human dose-escalation and expansion Phase 1-2 study designed to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of OR502 administered as a monotherapy and in combination with cemiplimab in subjects with advanced solid tumors.
Detailed Description:
This Phase 1-2 study is designed to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of OR502, a fully human IgG1 antibody that binds specifically to LILRB2, in subjects with advanced solid tumors. The study consists parts:
Part A: a dose-escalation phase to determine the maximum-tolerated dose (MTD), maximum achievable dose, or optimal dose of OR502 for further evaluation as monotherapy and in combination with cemiplimab in a maximum of approximately 48 subjects. Recruitment closed.
Part B: an expansion phase in subjects with advanced solid tumors treated with OR502 at 2 separate doses as monotherapy followed by combination with cemiplimab, and in subjects with previously treated platinum-resistant ovarian cancer (PROC) or cutaneous squamous cell carcinoma (CSCC) treated with OR502 at 2 separate doses in combination with cemiplimab. Up to approximately 20 subjects will be treated in each arm of the 3 Part B cohorts to further characterize safety, help determine the recommended Phase 2 dose (RP2D) for further development and determine preliminary anti-tumor activity. Up to approximately 120 subjects total will be treated in Part B. Not yet open.
Part B4: a mini-expansion cohort in subjects with a histological diagnosis of cutaneous melanoma with advanced/metastatic disease. Subjects must have received a PD-(L)1 inhibitor-based therapy, either alone or in combination with other anti-cancer agents, for at least 12 weeks. Subjects in this cohort will be treated with OR502 as monotherapy. Actively recruiting.
Part B5: a mini-expansion cohort in subjects with a histological diagnosis of non-small cell lung cancer (NSCLC) with advanced/metastatic disease. Subjects must have received a PD-(L)1 inhibitor-based therapy, either alone or in combination with other anti-cancer agents, for at least 12 weeks. Subjects in this cohort will be treated with OR502 in combination with cemiplimab. Actively recruiting.
