Summary

This trial is testing how well pembrolizumab works in treating patients with malignant mesothelioma. Pembrolizumab is a monoclonal antibody that works by blocking PD-1, which may stimulate an immune response and kill tumor cells.

Who is the study for?

This trial is for patients with malignant mesothelioma who have seen their disease progress after treatment with pemetrexed and platinum-based chemotherapy. They must have good organ function, not be pregnant or breastfeeding, agree to use contraception, and not have a history of severe autoimmune diseases or other conditions that could interfere with the study.

What is being tested?

The trial is testing pembrolizumab, an antibody therapy targeting PD-1 proteins on immune cells to potentially enhance the body's ability to fight cancer. It includes laboratory biomarker analysis and pharmacogenomic studies to understand how genes affect a person's response to drugs.

What are the potential side effects?

Pembrolizumab may cause immune-related side effects such as inflammation in various organs including lungs (pneumonitis), liver (hepatitis), intestines (colitis), hormone glands (endocrinopathies) and skin rash. Other possible side effects include fatigue, infusion reactions, infections due to lowered immunity.
