To compare the objective response rate (ORR) between subjects treated with intralesional administration of IFx-Hu2.0, as an adjunctive therapy, followed by pembrolizumab, and subjects treated by placebo followed by pembrolizumab using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
This Phase 2/3, multicenter, randomized, double-blind, placebo-controlled trial will evaluate the Objective Response Rate (ORR) of IFx-Hu2.0 as an adjunctive therapy to pembrolizumab in adult participants (≥18 years) with advanced or metastatic Merkel Cell Carcinoma. A total of 118 participants will be randomized to receive either IFx-Hu2.0 or placebo via intralesional injection in a single lesion, followed by pembrolizumab.
Inclusion: -Must be recurrent and/or unresectable Stage III or Stage IV American Joint Committee on Cancer (AJCC) (8th edition) and have histologically confirmed Merkel cell carcinoma -Participants should be CPI naïve i.e., no prior therapy with CPI including but not limited to Pembrolizumab, avelumab, ipilimumab, nivolumab. Exclusion: -Participants with prior systemic chemotherapy Participants with known active brain metastases with the exception of treated brain metastases that have imaging proving stability at least 4 weeks prior to the start of study treatment, no new metastases, and not requiring steroids.
