This is a first-in-human, Phase 1/2, open-label, multicenter, dose escalation and efficacy study designed to determine the safety and tolerability of repeated intratumoral injections of mRNA-2416 alone (Arm A) and in combination with intravenously administered durvalumab (Arm B) in participants with advanced relapsed/refractory solid tumor malignancies or lymphoma and to assess the ORR of mRNA-2416 alone and in combination with durvalumab in ovarian cancer based on RECIST v1.1. The study includes 2 treatment arms (mRNA-2416 monotherapy [Arm A],and mRNA-2416 + durvalumab [Arm B]), each arm of the study consists of a Dose Escalation period in non-visceral lesions followed by a Dose Confirmation period in visceral lesions and an Expansion period (Arm B only) in participants with ovarian cancer at the MTD/RDE as determined by the Dose Escalation period. Once the expected maximum tolerated dose/recommended dose for expansion (MTD/RDE) has been cleared in Dose Escalation for Arm A, Dose Escalation for Arm B will begin with mRNA-2416 at 1 dose level lower than the Arm A MTD/RDE.~Following completion of 6 cycles of mRNA-2416 + durvalumab (Arm B), participants may continue with durvalumab alone until disease progression, unacceptable toxicity, or 24 months of treatment (total), whichever is sooner.
This clinical study will assess the safety and tolerability of escalating doses of mRNA-2416 alone and in combination with administered fixed doses of durvalumab in participants with relapsed/refractory solid tumor malignancies or lymphoma, as well as the objective response rate (ORR) of mRNA-2416 alone or in combination with durvalumab in ovarian cancer based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. The applicable dose of mRNA-2416 will be injected directly into the participant's tumor (intratumoral) and the applicable dose of durvalumab will be administered intravenously.
