Summary

This trial is testing the effectiveness of the immunotherapy drug pembrolizumab in treating Merkel cell carcinoma before and after surgery. It also aims to assess any associated side effects.

Who is the study for?
This trial is for individuals with resectable stage I-III Merkel Cell Carcinoma (MCC). Participants must have a measurable tumor, provide tissue samples, agree to use contraception if applicable, and not be pregnant or breastfeeding. They should have good performance status and organ function. Those with certain hepatitis conditions may qualify but can't join if they've had recent cancer treatments, live vaccines, active infections including HIV/HBV/HCV, severe allergies to pembrolizumab components or certain medical conditions.
What is being tested?
The study tests the effects of pembrolizumab on MCC when given before surgery. It aims to see if this treatment reduces the risk of cancer coming back post-surgery. The drug's side effects will also be monitored in patients who receive it as part of their pre-and post-operative care.
What are the potential side effects?
Pembrolizumab may cause immune-related side effects such as inflammation in various organs like lungs (pneumonitis), liver problems, skin reactions, hormone gland issues (like thyroid disorders), infusion-related reactions and could potentially worsen autoimmune diseases.
