This clinical trial is focused on studying a type of kidney cancer known as metastatic renal cell carcinoma. The study is investigating the effectiveness and safety of a combination treatment using two medications, pembrolizumab and axitinib, compared to a single medication called sunitinib. Pembrolizumab, also known by its code name MK-3475, is a medication that helps the immune system fight cancer cells. Axitinib and sunitinib are both medications that work by blocking certain proteins that help cancer cells grow.
The purpose of this study is to compare how well patients with advanced kidney cancer respond to the combination of pembrolizumab and axitinib versus those who receive only sunitinib. Participants in the study will be randomly assigned to receive either the combination treatment or the single medication. The study will monitor the participants over a period to see how the cancer responds to the treatments and to check for any side effects.
Throughout the study, participants will receive regular check-ups and assessments to track their health and the progress of their cancer. The study aims to provide valuable information on which treatment option might be more effective for patients with this type of kidney cancer. The trial is expected to continue until the end of 2025, allowing researchers to gather comprehensive data on the treatments’ long-term effects.
