|Therapy Name||Belvarafenib + Cobimetinib|
|Drug Name||Trade Name||Synonyms||Drug Classes||Drug Description|
|Belvarafenib||HM95573|GDC-5573|RO7223619||RAF Inhibitor (Pan) 22||Belvarafenib (HM95573) selectively inhibits RAF dimer formation, leading to inhibition of ARAF, BRAF, and CRAF activity, and potentially resulting in tumor growth inhibition (PMID: 33953400).|
|Cobimetinib||Cotellic||GDC-0973||MEK inhibitor (Pan) 23 MEK1 Inhibitor 22 MEK2 Inhibitor 20||Cotellic (cobimetinib) is an allosteric inhibitor of MEK1/2, resulting in inhibition of extracellular signal-related kinase 2 (ERK2) phosphorylation and activation and decreased tumor cell proliferation (PMID: 22084396, PMID: 27956260). Cotellic (cobimetinib) is FDA approved for use in combination with Zelboraf (vemurafenib) in melanoma patients harboring BRAF V600E or V600K (FDA.gov).|

|NRAS Q61L||melanoma||sensitive||Belvarafenib + Cobimetinib||Preclinical - Cell line xenograft||Actionable||In a preclinical study, the addition of Cotellic (cobimetinib) to treatment with Belvarafenib (HM95573) in melanoma cell lines harboring NRAS Q61L resulted in greater inhibition of cell proliferation in culture compared to single agent alone, and led to decreased tumor volume, with increased efficacy and response durability in a cell line xenograft model (PMID: 33953400).||33953400|
|BRAF V600D||melanoma||sensitive||Belvarafenib + Cobimetinib||Preclinical - Cell culture||Actionable||In a preclinical study, the addition of Cotellic (cobimetinib) to treatment with Belvarafenib (HM95573) in a melanoma cell line harboring BRAF V600D resulted in greater inhibition of cell proliferation in culture compared to single agent alone (PMID: 33953400).||33953400|
|BRAF V600X||Advanced Solid Tumor||predicted - sensitive||Belvarafenib + Cobimetinib||Phase I||Actionable||In a Phase Ib trial, combination treatment with Belvarafenib (HM95573) and Cotellic (cobimetinib) was well-tolerated and demonstrated safety, and led to a confirmed partial response in 33.3% (3/9) solid tumor patients harboring BRAF V600 mutations (Annals of Oncology 32 (2021): S595; NCT03839342).||detail...|
|NRAS mutant||melanoma||predicted - sensitive||Belvarafenib + Cobimetinib||Phase I||Actionable||In a Phase I trial, Belvarafenib (HM95573) and Cotellic (cobimetinib) combination therapy was tolerable, and resulted in a response rate of 38% (5/13, 5 partial response) in patients with melanoma harboring NRAS mutations, with a median progression-free survival of 7.3 months (J Clin Oncol 39, no. 15_suppl (May 20, 2021) 3007-3007; NCT03284502).||detail...|
