Experimental: Dabrafenib + Trametinib
Subjects will receive Dabrafenib 150 mg twice daily orally plus Trametinib 2 mg once daily orally on a continuous basis. Dabrafenib will be administered under fasted conditions, either 1 hour (hr) before or 2 hours (hrs) after a meal with approximately 200 mL of water with an interval of 12 hours. Trametinib will be administered under fasted conditions, either 1 hr before or 2 hrs after a meal with approximately 200 mL of water. Subjects will take their dose of Trametinib concurrently with the morning dose of Dabrafenib. A treatment cycle is 28 days in duration. Subjects will continue treatment until an unacceptable toxicity, disease progression, or death occurs.
Dabrafenib is a 150 mg twice daily capsule administered orally on a continuous basis.
Trametinib is a 2 mg once daily tablet administered orally on a continuous basis.
- Overall Response Rate (ORR) [ Time Frame: From study treatment start date until first documented complete response or partial response, assessed up to 78 months (Interim Analysis cut-off date = 14-Sep-2020) ]Overall Response Rate (ORR) is defined as the percentage of participants with a confirmed overall response by investigator assessment as defined by the pre-specified response criteria for the disease type (RECIST v1.1, RANO, Consensus criteria for HCL and Multiple Myeloma). Specifically, ORR = (number of subjects with a confirmed overall response divided by the total number of subjects in the corresponding analysis population.
- Duration of Response (DoR) [ Time Frame: From first documented evidence of response (the first response prior to confirmation) until time of documented disease progression or death due to any cause, whichever comes first, assessed up to 78 months (Interim Analysis cut-off date = 14-Sep-2020) ]For the subset of subjects who showed a confirmed response as defined for each cohort, Duration of Response (DoR) is defined as the time (in weeks) from first documented evidence of response (the first response prior to confirmation) until time of documented disease progression or death due to any cause, whichever was first.
- Progression Free Survival (PFS) based on Local Investigator assessment [ 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 78 months (Interim Analysis cut-off date = 14-Sep-2020) ]Progression Free Survival (PFS) is defined as the interval between the first dose of study treatment and earlier date of first radiologically documented progression or death due to any cause. If the subject does not have a documented date of progression or death, PFS will be censored at the date of the last adequate assessment.
- Overall Survival (OS) [ Time Frame: From study treatment start date until date of of death from any cause, assessed up to 78 months (Interim Analysis cut-off date = 14-Sep-2020) ]Overall Survival (OS) is defined as the time from first dose until death due to any cause. Censoring will be performed using the date of last known contact for those who are alive at the time of analysis.
- Incidence of Adverse events (AEs) [ Time Frame: From study treatment start date till 30 days safety follow-up, assessed up to 78 months (Interim Analysis cut-off date = 14-Sep-2020) ]The distribution of adverse events (AE) will be done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs) and Serious Adverse Event (TESAEs) through the monitoring of relevant clinical and laboratory safety parameters.

NOTE: Subject should not have any clinically significant gastrointestinal (GI) abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels. For example, subjects should have no more than 50% of the large intestine removed and no sign of malabsorption (i.e., diarrhea).NOTE: If clarification is needed as to whether a condition will significantly affect the absorption of study treatments, contact the GSK Medical Monitor.
- Female Subjects of Childbearing Potential: Subjects must have a negative serum pregnancy test within 7 days prior to the first dose of study treatment and agrees to use effective contraception, throughout the treatment period and for 4 months after the last dose of study treatment.
- French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category
- Prior treatment with: BRAF and/or MEK inhibitor(s); anti-cancer therapy (e.g., chemotherapy with delayed toxicity, immunotherapy, biologic therapy or chemoradiation) within 21 days or prior nitrosourea or mitomycin C containing therapy within 42 days prior to enrollment and/or prior daily or weekly chemotherapy or biologic therapy without the potential for delayed toxicity within 14 days prior to enrolment or prior nvestigational drug(s) within 30 days or 5 half-lives, whichever is longer, prior to enrollment
