---|---|---|---|---|---|---|---|---|
BRAF del exon4-8 BRAF V600E | melanoma | predicted - resistant | Dabrafenib + Trametinib | Case Reports/Case Series | Actionable | In a clinical case study, a BRAF exon 4-8 deletion variant (reported as p61) was identified in the post-progression plasma ctDNA of two patients with metastatic melanoma harboring BRAF V600E who previously responded to treatment with the combination of Tafinlar (dabrafenib) and Mekinist (trametinib) (PMID: 33216826). | 33216826 | |
BRAF del exon4-8 BRAF V600E | melanoma | sensitive | Binimetinib + PF-07799933 | Preclinical - Pdx | Actionable | In a preclinical study, treatment with the combination of PF-07799933 and Mektovi (binimetinib) resulted in tumor regression in a patient-derived xenograft (PDX) model of melanoma harboring BRAF V600E and a BRAF exon 4-8 deletion variant (reported as p61 splice variant) (PMID: 38691346). | 38691346 | |
BRAF del exon4-8 BRAF V600E | melanoma | predicted - resistant | Vemurafenib | Case Reports/Case Series | Actionable | In a clinical case study, a deletion of BRAF exons 4-8 was identified in the post-progression biopsy of a melanoma patient harboring BRAF V600E who was treated with Zelboraf (vemurafenib) (PMID: 22113612). | 22113612 |
