MEKTOVI is a kinase inhibitor indicated, in combination with encorafenib, for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test.

Eligible patients were 18 years and older with a histologically confirmed diagnosis of locally advanced, unresectable/metastatic cutaneous melanoma or unknown primary melanoma (American Joint Committee on Cancer [AJCC] stage IIIB, IIIC, or IV) and the presence of BRAFV600E and/or BRAFV600K mutation in tumor tissue....The median PFS (95% CI) was 12.9 months (10.9 to 14.9) for COMBO300 versus 9.2  months (7.4 to 11.1) for ENCO300 (parts 1  and  2) and 7.4  months (5.6 to 9.2) for ENCO300 (part 2)....COMBO300 improved PFS, ORR, and tolerability compared with ENCO300, confirming the contribution of binimetinib to efficacy and safety.

COLUMBUS was conducted as a two-part, randomised, open-label phase 3 study...Eligible patients were aged 18 years or older and had histologically confirmed locally advanced (American Joint Committee on Cancer [AJCC] stage IIIB, IIIC, or IV), unresectable or metastatic cutaneous melanoma, or unknown primary melanoma; a BRAF V600E or BRAF V600K mutation;...1345 screened patients were randomly assigned to either the encorafenib plus binimetinib group (n=192), the encorafenib group (n=194), or the vemurafenib group (n=191)….median progression-free survival was 14·9 months (95% CI 11·0–18·5) in the encorafenib plus binimetinib group and 7·3 months (5·6–8·2) in the vemurafenib group (hazard ratio [HR] 0·54, 95% CI 0·41–0·71; two-sided p<0·0001)....Encorafenib plus binimetinib could represent a new treatment option for patients with BRAF-mutant melanoma.
