Brief Summary:
This was a four part, phase I/II 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 RP2R/MTD for doublet (D+P) and triplet (D+T+P) combinations in Part 1; 2) Assess clinical activity for these combinations in Part 2; 3) Determine RP2R/MTD for double (T+P) 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).

Condition or disease Intervention/treatment Phase
Cancer Drug: Dabrafenib Drug: Trametinib Drug: Panitumumab Device: 5-fluorouracil Phase 1 Phase 2

Detailed Description:

Part 1: Dose escalation This was a dose escalation part intended to evaluate safety, tolerability, PK, PD, clinical activity and determine RP2R/MTD for the doublet (D+P) and the triplet (D+T+P) combinations in patients with BRAF-mutation V600E positive advanced or metastatic CRC. A 3+3 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 (D+P)/(D+T+P) defined in Part 1.

Part 2B:

In this part, additional patients were enrolled into the triplet (D+T+P) 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 RP2R/MTD and initial clinical activity for the doublet (T+P) 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 RP2R/MTD for the doublet (T+P) 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 3+3 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 (T+P) 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.

  2. Overall Response Rate (ORR) [ Time Frame: From study treatment start date until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to approximately 90 months ]
    Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) was used for efficacy based on radiological assessment of tumor burden: CR = Complete Response, disappearance of all target lesions; PR = Partial Response, >=30% decrease in the sum of the longest diameter of target lesions; PD = progressive disease, >=20% increase in sum of target lesions and/or presence of new lesions and/or substantial increase in non-target lesion; SD = stable disease, response not meeting CR or PR or PD; ORR = overall response rate, defined as CR+PR

  3. Part 3: Progression Free Survival (PFS) [ Time Frame: From study treatment start date until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to approximately 90 months ]
    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.


Secondary Outcome Measures :
  1. Duration of Response (DoR) [ Time Frame: From study treatment start date until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to approximately 90 months ]
    Duration of Response (DoR) was defined as the time from the first documented occurrence of response (PR or CR) until the date of the first documented progression based on RECIST v1.1 or death.

  2. Progression Free Survival (PFS) [ Time Frame: From study treatment start date until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to approximately 90 months ]
    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.

  29. Change in Levels of Proteins/Ribonucleic Acid (RNA) [ Time Frame: Baseline, Day 15 ]
    H-score or "Histo-score" measures cell membrane immunohistochemistry staining intensity in a fixed field. Membrane staining is categorized as 1+, 2+, or 3+. Minimum score is 0, maximum score is 300 (no subscale values are reported). H-score values themselves are not considered to be better or worse - measurements for levels of proteins/ribonucleic acid (RNA) are surrogate for MAPK pathway activity. Low values = low pathway activity. High values = high pathway activity. Changes in mean phosphorylated-ERK (pERK) and phosphorylated ribosomal protein S6 (pS6) H-score from baseline indicate changes in MAPK pathway activity that may be associated with treatment arms. A positive change from baseline suggests increased pathway activity. A negative change from baseline suggests decreased pathway activity. Total score is calculated as follows: [1 x (% cells 1+) + 2 x (% cells 2+) + 3 x (% cells 3+)].

    Duration of Response (DoR) was defined as the time from the first documented occurrence of response (PR or CR) until the date of the first documented progression based on RECIST v1.1 or death.

  32. Part 3: Overall Survival (OS) [ Time Frame: From study treatment start date until date of of death from any cause, assessed up to approximately 90 months ]
    Overall Survival (OS) was defined as the time to death due to any cause.

  33. Part 3: Number of Participants With Treatment Emergent Adverse Events [ Time Frame: From study treatment start date till 30 days safety follow-up, assessed up to approximately 90 months ]
    The distribution of adverse events (AE) will be done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs), Serious Adverse Event (TESAEs) and Deaths due to AEs, through the monitoring of relevant clinical and laboratory safety parameters.
