U.S., Dec. 25 -- ClinicalTrials.gov registry received information related to the study (NCT07302347) titled 'A Study of Pembrolizumab in Japanese Pediatric Participants With Solid Tumors or Lymphomas and Japanese Adult Participants With Merkel Cell Carcinoma (MK-3475-G21/KEYNOTE-G21)' on Dec. 11.

Brief Summary: Researchers are looking for new ways to treat people with solid tumors, lymphomas (blood cancers), and a certain type of skin cancer. The goals of this study are to learn:
