A Phase 1 Dose-Escalation and Expansion Study of Intratumorally Administered ONM-501 Alone and in Combination with Cemiplimab in Patients with Advanced Solid Tumors and Lymphomas

Description

A phase 1, multicenter, open label, non-randomized dose escalation and dose expansion study to examine the maximum tolerated dose, (MTD), minimum effective dose (MED) and/or recommended dose for expansion (RDE) of intratumoral ONM-501 as monotherapy and in combination with a PD-1 checkpoint inhibitor in patients with advanced solid tumors and lymphomas.This Phase 1, multi-center trial will consist of three parts: monotherapy dose escalation; combination therapy dose finding; and combination therapy dose expansion exploring two doses in specific tumor indication(s). Each dosing cycle of ONM-501 will be 21 days. ONM 501 will be administered as intratumoral injections once per week for three weeks (on Days 1, 8, and 15), followed by three weeks without ONM-501 administration. The monotherapy dose escalation will utilize an accelerated titration method. The combination agent will be administered according to standard protocol, once every three weeks. This phase will evaluate ONM-501 in co
