Promising drug cocktail aims to shrink penile cancer before surgery

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

1. Inclusion Criteria （1）Histologically/cytologically confirmed penile squamous cell carcinoma (PSCC); （2）EGFR expression (IHC 1+, 2+, or 3+) confirmed by local pathology department; （3）No prior systemic therapy, or recurrence ≥6 months after adjuvant therapy for radical resection; （4）Male, aged ≥18 years; （5）Cytologically positive or clinically palpable inguinal lymphadenopathy, fixed mass, radiologically diagnosed pelvic lymph node metastasis, or penile preservation difficulty (unable to perform surgery with negative margin and functional penile stump preservation); （6）At least one measurable lesion per RECIST 1.1; （7）Adequate organ function: * Left ventricular ejection fraction (LVEF) ≥50%; * Hemoglobin (HGB) ≥90 g/L, white blood cell (WBC) ≥3.0×10⁹/L, absolute neutrophil count (ANC) ≥1.5×10⁹/L, platelet (PLT) ≥80×10⁹/L; * Total bilirubin (TBIL) ≤1.5×ULN, AST/ALT ≤2.5×ULN (≤5×ULN for liver metastasis), serum creatinine (Cr) ≤1.5×ULN or creatinine clearance (CrCl) ≥50 mL/min; （8）Voluntarily participate, understand the study, and sign informed consent form. 2. Exclusion Criteria （1）Prior systemic therapy (except recurrence ≥6 months after adjuvant chemotherapy for radical resection); （2）Severe concurrent diseases or poor physical condition unsuitable for treatment/surgery (e.g., severely ulcerated/infected inguinal lymph nodes with high risk of poor wound healing); （3）Uncontrolled comorbidities: uncontrolled infection, active tuberculosis, uncontrolled diabetes, cardiovascular diseases (NYHA class III/IV heart failure, ≥grade 2 heart block, myocardial infarction within 12 months, unstable arrhythmia/angina, cerebral infarction within 6 months), interstitial lung disease, deep vein thrombosis/pulmonary embolism within 12 months, decompensated cirrhosis; （4）Active autoimmune diseases requiring systemic treatment within 2 years (except physiological replacement therapy); （5）Positive serological tests: HIV positive; HBsAg positive with HBV DNA ≥2000 copies/mL; HCV antibody positive with positive HCV RNA; （6）Major surgery within 4 weeks prior to enrollment, prior allogeneic hematopoietic stem cell transplantation or solid organ transplantation; （7）Vaccination with anti-tumor vaccine within 4 weeks prior to enrollment or planned during the study; （8）Other conditions deemed unsuitable by the investigator.
