The regulatory agency granted the approval based on findings from the Phase II PHAROS clinical trial currently under way.
The multicentre, open-label, single‑arm trial is assessing Braftovi plus Mektovi both in patients who are treatment-naïve and those who had previously received treatment.
PHAROS has already met key efficacy outcome measures of objective response rate (ORR) and duration of response in both subject groups.
Pfizer noted that the ORR was 75% in treatment-naïve subjects and that 59% responded for a minimum of 12 months.
