Summary

BRF112680 is a first-time-in-human study to establish the recommended dose and schedule of the orally administered GSK2118436. The recommended dose and regimen will be selected based on the safety, pharmacokinetic, and pharmacodynamic profiles observed after the treatment of subjects with solid tumors. This is a two-part study. Part 1 will identify the recommended Part 2 dose using a dose-escalation procedure. Escalation may proceed until either a maximum tolerated dose is established, or the toxicokinetic safety limit is reached. The recommended Part 2 dose will be expanded to up to 12 patients. Part 2 will explore further the safety, tolerability, and clinical activity of GSK2118436 in subjects with BRAF mutation-positive tumors. In addition, the effect of GSK2118436 on midazolam will be assessed in a subset of patients in Part 2. Biologically active doses will be identified by measurement of pharmacodynamic markers in tumor tissue and blood across a range of doses and these doses may be explored in Part 2.

Conditions

Interventions

DRUG

GSK2118436

Dose escalation with GSK2118436 may proceed until either a maximum tolerated dose is established, or the toxicokinetic safety limit is reached.

DRUG

GSK2118436

Part 2 will use the recommended Part 2 dose of GSK2118436 identified during Part 1 of the study. Biologically active doses will be identified by measurement of pharmacodynamic markers in tumor tissue and blood across a range of doses and these doses may be explored in Part 2.

DRUG

Midazolam

Midazolam will be administered alone and with GSK2118436 in a sub-set of subjects in Part 2 to study the effect of GSK2118436 on CYP3A using midazolam as a probe.
