Pembrolizumab Combined With Cisplatin-based Chemotherapy as First-line Systemic Therapy in Advanced Penile Cancer — HERCULES  

Penile Carcinoma Clinical Trial

Official title: A Phase II Trial of Pembrolizumab Combined With Cisplatin-based Chemotherapy as First-line Systemic Therapy in Advanced Penile Cancer

Status Completed

Clinical Trial Summary

This is a phase II clinical trial evaluating activity, safety and patients reported outcomes of first-line pembrolizumab plus cisplatin (or carboplatin) plus 5-FU for patients with advanced penile squamous cell carcinoma.

The primary endpoint is overall responsa rate according to RECIST v1.1 at week 24.

Clinical Trial Description

Advanced penile squamous cell carcinoma is associated with dismal survival rates and a major impact on the quality of life. To date, unresectable or metastatic disease is managed by systemic therapy with platinum-based chemotherapy for patients with good performance status. The median PFS and OS on first-line platinum-based chemotherapy vary between 3-4 and 7-15 months, respectively. Chemotherapy induces objective responses in only 20-30% of penile cancer patients with rare complete responses and systemic treatment has not changed for decades. Therefore, this study's rationale is to explore the efficacy and safety of pembrolizumab combined with standard-of-care cisplatin(or carboplatin) plus 5-fluorouracil as part of the first-line therapy. Patients will receive pembrolizumab 200mg IV every three weeks with a maximum duration of 2 years (34 cycles-counting the combination with chemotherapy) in case of no progressive disease or intolerance. The investigators hypothesized that the combination of immunotherapy with standard cytotoxic chemotherapy may improve the overall response rate by RECIST v1.1 in this patient population. ;
