Plain-language summary
This is a phase 1b/2, open-label, two-part, multicenter trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of intratumoral cavrotolimod injections alone and in combination with intravenous pembrolizumab or cemiplimab in patients with Merkel Cell Carcinoma, cutaneous squamous cell carcinoma, and advanced solid tumors.
Phase 1b of this trial is a 3+3 dose escalation study evaluating escalating or intermediate dose levels of cavrotolimod given with a fixed dose of pembrolizumab.
The Phase 2 dose expansion part of the study will consist of two primary cohorts of patients: Merkel cell carcinoma and cutaneous squamous cell carcinoma. Patients in the Merkel Cell Carcinoma cohort will receive IT cavrotolimod combined with a fixed, standard dose of pembrolizumab while the Cutaneous Squamous Cell Carcinoma cohort will receive IT cavrotolimod combined with a fixed, standard dose of cemiplimab. The Phase 2 dose expansion is designed to provide a preliminary estimate of efficacy in patients that have progressed on an anti-PD-(L)1 CPI.
