Detailed Description
PRIMARY OBJECTIVE:
I. To estimate the best response rate of enfortumab vedotin treatment for patients with metastatic penile squamous cell carcinoma (mPSCC).
SECONDARY OBJECTIVES:
I. To determine overall response rate (ORR). II. To determine safety and tolerance of enfortumab vedotin in men with mPSCC. III. To characterize duration of response to enfortumab vedotin in mPSCC. IV. To estimate median overall survival and progression-free survival in men with mPSCC treated with enfortumab vedotin.
V. To analyze response in subgroups by human papillomavirus (HPV) status (related/unrelated as assessed by p16 biomarker).
OUTLINE:
Patients receive enfortumab vedotin intravenously (IV) over 30 minutes on days 1,8 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 3 months until progressive disease, followed by every 6 months for up to 5 years from registration.

Failure to recover from any of the following therapies prior to registration:
- Major surgery
- Radiotherapy, chemotherapy, biologics, investigational agents, and/or antitumor treatment with immunotherapy
- Immunocompromised patients and patients known to be human immunodeficiency virus (HIV) positive
Uncontrolled intercurrent illness including, but not limited to:

Duration of Response
Time Frame: Up to 5 years
|
