Frequently asked questions about Belvarafenib

What is Belvarafenib used for?

Belvarafenib is an investigational small molecule being studied for the treatment of NRAS-mutant advanced melanoma. It is being evaluated as a single agent and in combination with cobimetinib or cobimetinib plus nivolumab in patients with this specific biomarker-selected population. It is not yet approved for any indication.

What does Belvarafenib target?

Belvarafenib targets RAF1, BRAF, and ARAF kinases. It is a small molecule inhibitor designed to inhibit these RAF family kinases, which are components of the MAPK signaling pathway often dysregulated in NRAS-mutant melanoma.

Who is developing Belvarafenib?

Belvarafenib is being developed by Roche Holding AG, which trades under the ticker RHHBY. Roche is the sponsor of the clinical trial evaluating the drug in NRAS-mutant advanced melanoma.

What phase is Belvarafenib in?

Belvarafenib is in Phase 1 clinical development. The ongoing trial is a Phase 1 study evaluating its safety and activity as a single agent and in combinations. It is investigational and has not been approved by the FDA or any regulatory agency.

What clinical trials is Belvarafenib in?

Belvarafenib is being studied in one active clinical trial, NCT04835805, titled "A Study to Evaluate the Safety and Activity of Belvarafenib as a Single Agent and in Combination With Either Cobimetinib or Cobimetinib Plus Nivolumab in Patients With NRAS-mutant Advanced Melanoma." The trial is active but not recruiting, with an estimated enrollment of 65 patients across the United States, Australia, Canada, Germany, and South Korea.
