Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Part B of the study enrolled cohorts in escalating doses to identify a set of allowable doses to be expanded in Part C. Subjects were enrolled in a 3+3 cohort design, with provisional dose levels of both drugs. The decision regarding escalation to the next dose levels of GSK1120212 and GSK2118436 was further guided by a Bayesian logistic regression model. The first cohort started at low doses for both drugs. Doses up to 300 mg/day for GSK2118436 and up to 3 mg QD for GSK1120212 were studied. The starting dose might be lowered based on emerging data from other studies and from Part A.
Expansion cohorts enrolled in Part C at dose levels of GSK2118436 and GSK1120212 as defined in Part B. One of the selected doses might include GSK2118436 administered as monotherapy at a tolerable dose (less than or equal to the maximum tolerated dose) determined in BRF112680. Part C was a randomized open-label Phase II portion of the study, and consisted of expansion cohorts investigating 2 to 3 dose levels of GSK2118436 and GSK1120212 dosing in combination, and GSK2118436 administered as monotherapy. Subjects were assigned to treatment arms in a randomized fashion to compare tolerability and safety. Population PK parameters, clinical activity, durability of response and safety of GSK2118436 and GSK1120212 dosed orally in combination and GSK2118436 as monotherapy were evaluated.
Part D consisted of evaluation of the pharmacokinetics of GSK2118436 HPMC capsules administered as monotherapy and in combination with GSK1120212. Pharmacokinetics of GSK2118436 was assessed following a single dose on Day 1 and after repeat dosing (Day 21) and compared between combination and monotherapy. The pharmacokinetics of GSK1120212 was also be assessed. Safety, tolerability and clinical activity were evaluated in 4 dosing cohorts. These cohorts might be expanded for additional safety data. Subjects were randomized to different cohorts.
