This is a Phase 1, open label, multicenter, multidose, first-in-human (FIH) dose escalation and expansion to determine the safety and tolerability, recommended phase 2 dose and pharmacology, and antitumor activity of RTX-321 in adult patients with persistent, recurrent, or metastatic, unresectable cervical cancer (squamous, adeno, or adenosquamous histology), HNSCC, or squamous cell cancer of the anal canal that is not amenable to curative therapy. Prior to study screening, all patients must be confirmed to be HLA-A*02:01 positive. Documentation of an HPV 16+ tumor is required at prescreening for patients with cervical cancer and HNSCC. RTX-321 is a cellular therapy that expresses 4-1BBL, IL-12, and HPV-16 Antigen with the goal of harnessing the innate and adaptive immune systems for the treatment of cancer. The study will include a monotherapy dose escalation phase followed by an expansion phase.
This is an open-label, multicenter, multiple-ascending dose, FIH, Phase 1 study of RTX-321 for the treatment of patients that are HLA-A*02:01 positive with persistent, recurrent, or metastatic, unresectable, HPV 16+ cancers.
