전이성/재발성 음경편평상피세포암종에서 아미반타마브

This is a collaborative, multicenter, open-label, Phase 2 clinical trial (APOLO TRIAL / LACOG 2425) designed to evaluate the efficacy, safety, and tolerability of subcutaneous amivantamab monotherapy in adult patients with histologically confirmed recurrent or metastatic penile squamous cell carcinoma (PSCC). Eligible participants must have experienced disease progression on or after receiving at least one platinum-based chemotherapy regimen (with or without immunotherapy). The study allocates participants into two parallel non-randomized cohorts based on their human papillomavirus (HPV) status (HPV-positive and HPV-negative).
