Summary

This trial is testing pembrolizumab in combination with chemotherapy to treat small cell/neuroendocrine cancers of the urothelium or prostate.

Who is the study for?

This trial is for adults with advanced small cell/neuroendocrine cancers of the bladder, urethra, or prostate. Participants must have adequate organ function and no recent blood transfusions. They should not have had certain cancer treatments recently and agree to use contraception. Exclusions include active autoimmune disease, known psychiatric disorders that affect participation, recent other cancer therapies, severe allergies to trial drugs, active infections like HIV or hepatitis B/C, pregnant or breastfeeding women.

What is being tested?

The study tests pembrolizumab (an immune system booster) combined with chemotherapy drugs cisplatin, carboplatin, docetaxel, and etoposide in patients with specific urothelial/prostate cancers. The goal is to see if this combination is more effective than current treatments at stopping cancer growth by killing tumor cells or preventing them from dividing and spreading.

What are the potential side effects?

Possible side effects include reactions related to the immune system affecting various organs (like inflammation), fatigue from treatment-related anemia (low red blood cell count), nausea/vomiting due to chemotherapy's effect on the stomach lining; hair loss from damage to hair follicles; kidney/liver function changes due to drug metabolism; increased risk of infection as a result of lowered white blood cell counts.

Experimental Treatment

Group I: Treatment (pembrolizumab, platinum-based chemotherapy)Experimental Treatment5 Interventions

Participants receive pembrolizumab IV over 30 minutes on day 1. Courses repeat every 3 weeks for 2 years in the absence of disease progression or unacceptable toxicity. Participants also receive standard of care chemotherapy comprising either etoposide IV on days 1-3 and cisplatin IV or carboplatin IV on day 1 (Cohort 1), or etoposide IV on days 1-3, carboplatin IV on day 1, and docetaxel IV on day 1 (Cohort 2). Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
