Frequently asked questions about MK-0482

What is MK-0482 used for?

MK-0482 is an investigational monoclonal antibody being studied for the treatment of advanced solid tumors, or neoplasms. It was evaluated as monotherapy and in combination with pembrolizumab in adult participants with advanced solid tumors. It is not approved for any indication and remains in clinical development.

Who is developing MK-0482?

MK-0482 is being developed by Merck & Company, Inc., which trades under the ticker MRK. Merck sponsored the Phase 1 study of MK-0482 in advanced solid tumors, both as a single agent and in combination with pembrolizumab.

What phase is MK-0482 in?

MK-0482 is in Phase 1 clinical development. Its single registered trial, NCT03918278, was a Phase 1 study that has been completed. The drug is investigational and has not received FDA approval for any indication.

What clinical trials is MK-0482 in?

MK-0482 has been studied in one clinical trial, NCT03918278, titled A Study of MK-0482 as Monotherapy and in Combination With Pembrolizumab (MK-3475) in Participants With Advanced Solid Tumors. The Phase 1 trial enrolled 222 participants across the United States, Australia, Canada, Chile, Israel, Italy, South Korea, and Spain, and is completed.

Is MK-0482 biomarker selected?

Yes, the MK-0482 Phase 1 trial NCT03918278 was biomarker selected, meaning enrollment was guided by biomarker criteria. The study evaluated MK-0482 as monotherapy and in combination with pembrolizumab in adults with advanced solid tumors.
