Phase 1 Study of Intratumoral ONM-501 Alone and with Cemiplimab for Advanced Solid Tumors and Lymphomas

What this Trial Is About

Researchers are evaluating ONM-501, a drug given as intratumoral injections, alone and in combination with cemiplimab, an immune checkpoint inhibitor, in patients with advanced solid tumors and lymphomas. This phase 1 study aims to find the maximum tolerated dose, minimum effective dose, and recommended dose for expansion of ONM-501. The study includes patients with various advanced cancers who have no alternative standard therapies available. The trial has three parts monotherapy dose escalation, combination therapy dose finding, and combination therapy dose expansion. ONM-501 is given once per week for three weeks followed by three weeks off, in 21-day cycles. Cemiplimab is given intravenously every three weeks during the combination phases. Dose escalation uses special methods to gradually increase doses, and after doses are established, patients will enroll in expansion cohorts for specific tumor types. Participants will have regular assessments including monitoring for side effects, blood tests to measure drug levels, and evaluation of tumor response over up to 24 months. Researchers will track treatment-emergent adverse events, dose-limiting toxicities, and serious adverse events. Outcomes such as objective response rate, duration of response, progression-free survival, and overall survival will also be recorded. The study involves close safety monitoring and follow-up throughout the treatment and observation periods.
