This was a Phase II, multicenter, non-randomized, open-label study to assess the efficacy, safety, and tolerability of dabrafenib administered as a single agent and in combination with trametinib in stage IV disease to subjects with BRAF mutant advanced non-small cell lung cancer. Central confirmation testing for the BRAF V600E mutation was performed and a sufficient number of subjects were enrolled with the intent of having at least 125 centrally confirmed subjects among the three cohorts.

  1. description
    Progression Free Survival (PFS) was defined as the time from study treatment start date to the date of first radiologically documented progression or death due to any cause. If a patient did not progress or die at the time of the analysis data cut-off or start of new antineoplastic therapy, PFS was censored at the date of the last adequate tumor assessment before the earliest of the cut-off date or the start date of additional anti-neoplastic therapy. Progression was defined using Response Evaluation Criteria In Solid Tumors Criteria RECIST v1.1, as 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline and/or unequivocal progression of the non-target lesions and/or appearance of a new lesion. In addition to the relative increase of 20%, the sum must demonstrate an absolute increase of at least 5 mm.

Full study description
brief Summary
This was a Phase II, multicenter, non-randomized, open-label study to assess the efficacy, safety, and tolerability of dabrafenib administered as a single agent and in combination with trametinib in stage IV disease to subjects with BRAF mutant advanced non-small cell lung cancer. Central confirmation testing for the BRAF V600E mutation was performed and a sufficient number of subjects were enrolled with the intent of having at least 125 centrally confirmed subjects among the three cohorts.
detailed Description
Subjects enrolled in Cohort A (Monotherapy Population) were required to have relapsed or progressed on at least one platinum based chemotherapy regimen prior to enrollment (i.e. dabrafenib was no less than second line treatment for metastatic disease). Additional lines of prior anti-cancer therapy were allowed. Subjects received dabrafenib as a single agent at the recommended dose of 150 mg twice daily. A 2 stage design with a planned sample size of 40 subjects was initially used for Cohort A. Subjects enrolled in Cohort B (Combination Second-Line Population) were required to have relapsed or progressed on at least one platinum based chemotherapy prior to enrollment but did not receive more than 3 prior systemic anti-cancer therapies (i.e. dabrafenib/trametinib were second, third, or fourth line treatment for metastatic disease). Subjects received the recommended dose of both drugs (dabrafenib 150 mg twice daily and trametinib 2 mg once daily). Subjects enrolled in Cohort C (Combination First-Line Population) did not receive prior systemic anti-cancer therapies for metastatic disease (i.e. dabrafenib/trametinib was first line treatment for metastatic disease). Subjects received the recommended dose of both drugs (dabrafenib 150 mg twice daily and trametinib 2 mg once daily). Crossover: Subjects receiving and adequately tolerating dabrafenib as a single agent and who continued to meet the inclusion and exclusion criteria (including the additional criteria for combination therapy) had the option to crossover to dabrafenib (150 mg BID) and trametinib (2 mg once daily) combination treatment at the time of radiologic disease progression with prior approval from a Medical Lead. If a subject was receiving less than 150 mg BID of dabrafenib at the time of the crossover, the subject was to continue at the lower dose of dabrafenib when initiating combination therapy.
