Brief Summary:
This was a four part phase III study aimed to evaluate the safety tolerability and efficacy of combination of an anti-EGFR antibody panitumumab P either with a BRAF inhibitor dabrafenib D GSK2118436 alone or with the combination of a BRAF inhibitor and a MEK inhibitor trametinib T GSK1120212 in patients with BRAF-mutant V600E advanced or mCRC The goal was to 1 Determine RP2RMTD for doublet DP and triplet DTP combinations in Part 1 2 Assess clinical activity for these combinations in Part 2 3 Determine RP2RMTD for double TP combination in Part 4A and assess clinical activity of this combination in two patient populations in Part 4B patients with BRAF-V600E mutation-positive advanced or metastatic CRC and patients with advanced or metastatic CRC with secondary resistance to anti-EGFR therapy
Detailed Description:
Part 1 Dose escalation This was a dose escalation part intended to evaluate safety tolerability PK PD clinical activity and determine RP2RMTD for the doublet DP and the triplet DTP combinations in patients with BRAF-mutation V600E positive advanced or metastatic CRC A 33 dose escalation procedure was followed Dosing for dabrafenib and trametinib was continuous daily dosing while panitumumab was dosed once every two weeks Q2W Patients were evaluated for dose-limiting toxicities DLTs during the first 28 days of treatment
Part 2A
This was a cohort expansion part to assess the safety and preliminary clinical activity of the optimal safe and tolerable dose combinations DPDTP defined in Part 1
Part 2B
In this part additional patients were enrolled into the triplet DTP combination at two dose levels in to further explore safety tolerability and clinical activity Up to 10 patients each with no prior treatment First Line Population and up to 20 patients each with at least one prior treatment Second to Fourth Line Population were planned to be enrolled in dose Cohorts 3A and 4
Part 3 Randomized Phase 2 Study The randomized phase 2 portion Phase 3 of the study was not pursued as the observed responses in any of the cohorts did not meet the predefined criteria at the time of the preliminary analysis data cut-off date 06-May-2016
Part 4 This part was designed to identify the RP2RMTD and initial clinical activity for the doublet TP combination in patients BRAF-mutation V600E positive advanced or metastatic CRC and advanced or metastatic CRC with secondary resistance to prior anti-EGFR therapy
Part 4A Dose Escalation This was a dose escalation part intended to determine RP2RMTD for the doublet TP combination in patients with BRAF-mutation V600E positive advanced or metastatic CRC Approximately 18 patients 6 each cohort were planned to be enrolled in Part 4A A 33 dose escalation procedure was followed Dosing for trametinib was continuous daily dosing while panitumumab was dosed once every two weeks Q2W Patients were evaluated for DLTs during the first 28 days of treatment
Part 4B Cohort Expansion This was a cohort expansion part intended to evaluate safety and efficacy of the doublet TP combination Up to 20 patients in each of two expansion cohorts were planned to be enrolled at the starting dose cohort or MTD from Part 4A
