Adults who:
- Have Merkel Cell Carcinoma that is advanced or metastatic
- Have no prior immunotherapy for advanced or metastatic disease

What is Involved?

If you choose to join this study, you will:

Be assigned to a study group (like a flip of a coin) to either:

- Get the study drug plus radiation
-- Get the radiation during the first 21 days of MK-3475 (pembrolizumab) only
-- Get radiation treatment that will include a planning session and 3 treatments
-- Be followed closely by your study doctor for side effects and your condition every 3 months for five years after you have finished the MK-3475 (pembrolizumab)


- Get the study drug alone

The study drug MK-3475 (pembrolizumab) will be given through a vein in your arm for up to two years as long as it is helping treat your cancer.
