About this trial

This is an open-label, multicenter, single-arm Phase 2 clinical trial evaluating neoadjuvant pucotenlimab (anti-PD-1 immunotherapy) combined with becotatug vedotin (EGFR-targeted antibody-drug conjugate, ADC) for adults with locally advanced penile squamous cell carcinoma. Eligible patients have high-risk disease defined as T4 primary tumor with any nodal status or any T stage with N2-N3 lymph node metastasis and no distant metastasis.

All participants receive up to 4 cycles of combination neoadjuvant therapy every 3 weeks. After treatment completion, a multidisciplinary team will assess if consolidative surgery can be performed. Patients who undergo surgery will continue single-agent pucotenlimab adjuvant treatment for 17 additional cycles (approximately 1 year).

The primary goal is to measure the pathological complete response (pCR) rate. Secondary goals include objective response rate (ORR), progression-free survival (PFS),overall survival (OS) and safty profiles. Blood and tumor tissue samples will be collected to explore biomarkers that may predict treatment response and drug resistance. A total of 29 male patients will be enrolled.
