Study Details

Study Description

Brief Summary

The study drug, GSK2820151, is a Bromodomain (BRD) and Extra-Terminal (BET) inhibitor arising from a distinct structural class. GSK2820151 potently inhibits tumor growth in vitro and in vivo in animal models. This first time in human (FTIH), open-label, dose escalation study is to assess the safety, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary clinical activity of GSK2820151 in subjects with advanced or recurrent solid tumors. The objective is to determine the safety, tolerability and maximum tolerated dose (MTD) of GSK2820151 in subjects 18 years or older with advanced or recurrent solid tumors. Eligible subjects with advanced or recurrent solid tumors will be enrolled in the dosing cohorts until MTD is established. All subjects will receive study drug. Subjects may continue treatment in the study until disease progression, unacceptable toxicity, or withdrawal of consent. The duration of study will depend on recruitment rates and the timing of subjects' duration on study (withdrawal rates due to toxicity or progression). It is anticipated that approximately 30 to 50 subjects will be enrolled.

Arms and Interventions

Arm

Intervention/Treatment

Experimental: GSK2820151 arm An accelerated dose escalation phase will be utilized in order to minimize sub-optimal drug exposures, followed by a conventional 3+3 dose escalation phase to achieve MTD. Initially, one subject per dose cohort will be recruited (accelerated dose escalation phase) until the first instance of a >=Grade 2 drug related toxicity or dose-limiting toxicity (DLT). Further cohorts will be recruited in blocks of three subjects (3+3 dose escalation phase). Projected dose levels are 3 mg, 6 mg, 12 mg, 20 mg, 40 mg, 60 mg, 100 mg, 150 mg, 200 mg, and 300 mg. Additional subjects may be enrolled at previously cleared dose levels in order to obtain further data for PK and/or PD analysis. Once MTD is determined, additional subjects (18 subjects total at MTD) may be enrolled to collect additional safety data.

Drug: GSK2820151; GSK2820151 is provided as capsules containing 1 mg, 5 mg, 10 mg, 50 mg, or 100 mg of GSK2820151 as free base equivalent to be administered orally. The dosing regimen is as follows: Week 1 - once daily on days 1, 3, 4, and 5; Week 2 - once daily on days 1, 2, 3, 4, 5; and Weeks 3 and beyond - once daily continuously.

25. Secondary Outcome

Title	Time Invariance of GSK2820151
Description	Blood samples were collected at indicated timepoints for analysis of time invariance. Time invariance was calculated as the ratio of AUC(0-tau) on Week 3 Day 4 divided by AUC(0-inf) on Week 1 Day 1. The ratio for SD was calculated from AUC(0-tau) on Week 3 Day 4 and AUC(0-inf) on Week 1 Day 1 parameters for each participant.
Time Frame	Week 1, Day 1 (Pre-dose, 15 and 30 minutes, 1, 2, 4, 8, 16, 24 and 33 hours post-dose); Week 3, Day 4 (Pre-dose, 15 and 30 minutes, 1, 2, 4, 8, 16, 24 and 48 hours)
