Merck U03B: Targeted combination therapies for second line ccRCC patients (Renal Cell Cancer) - Clinical Trial

What is the Purpose of this Study?


We are doing this study to find out what combinations of experimental and approved drugs may be safe and effective treatments for your cancer. The approved drugs used in this study are pembrolizumab and lenvatinib. The four experimental drugs used in this study are called MK-1308A, MK-4280A, MK-4830, and MK-6482. No combination of any of these drugs is approved for the treatment of ccRCC.

What is Involved?


If you choose to join the study, you will:
- Have physical exams
- Have blood draws
- Have imaging tests (CT/MRI, EKG, echocardiogram, bone scans)
- Receive a random assignment (fair chance) to 1 of 6 study groups

Each study group will take a different combination of the study drug(s). The 6 possible study drug combinations are:
- MK-1308A alone
- MK-4280A alone
- Pembrolizumab + MK-4830
- Pemborlizumab + MK-6482
- Lenvatinib + MK-6482
- Pembrolizumab + lenvatinib

This study is not blinded. That means both you and your doctor will know the group to which you are assigned and what study drug(s) you will take.
