Description of intervention(s) / exposure
Treatment: Drugs - GSK2118436
Treatment: Drugs - GSK2118436
Treatment: Drugs - Midazolam

Experimental: Part 1 - 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. Subjects may dose up to three times a day.

Experimental: Part 2 - Part 2 will explore further the safety, tolerability, and clinical activity of GSK2118436 in subjects with BRAF mutation-positive tumors using the recommended part 2 dose identified during Part 1. 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.


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

Treatment: Drugs: 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.

Treatment: Drugs: 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.

these medications during treatment with GSK2118436.

- Current use of therapeutic warfarin.

- Any major surgery, radiotherapy, or immunotherapy within 4 weeks prior to first dose.
Limited radiotherapy within 2 weeks prior to first dose.

weeks for prior nitrosourea or mitomycin C). Chemotherapy regimens given continuously
or on a weekly basis with limited potential for delayed toxicity within 2 weeks prior
to first dose.

- Unresolved toxicity greater than National Cancer Institute Common Terminology Criteria
for Adverse Events, version 3.0 Grade 1 from previous anti-cancer therapy except
alopecia unless agreed to by a GSK Medical Monitor and the investigator.

- Presence of active gastrointestinal disease or other condition that will interfere
significantly with the absorption, distribution, metabolism, or excretion of drugs.

- A history of known HIV infection.

- Primary malignancy of the central nervous system.

- Symptomatic or untreated leptomeningeal or brain metastases or spinal cord
compression. Subjects previously treated for these conditions that are asymptomatic
and off corticosteroids for at least two weeks are permitted. Brain metastases must be
stable for at least 3 months with verification by imaging (brain MRI completed at
screening). Subjects are not permitted to receive enzyme inducing anti-epileptic drugs
(EIAEDs). In Part 2 of the study, subjects with asymptomatic, untreated brain
metastases that have not been stable for 3 months may be enrolled with approval of the
GSK medical monitor. These subjects can be on a stable dose of corticosteroids.

- History of alcohol or drug abuse within 6 months prior to the screen visit.

- Psychological, familial, sociological, or geographical conditions that do not permit
compliance with the protocol.

- Concurrent condition that in the investigator's opinion would jeopardize compliance
with the protocol.

- QTc interval greater than or equal to 480 msecs.

- History of acute coronary syndromes (including unstable angina), coronary angioplasty,
or stenting within 24 weeks prior to the first dose.

- Class II, III, or IV heart failure as defined by the New York Heart Association (NYHA)
functional classification system.

- Abnormal cardiac valve morphology (subjects with minimally abnormalities can be
entered on study with approval from the GSK medical monitor).

- Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs
chemically related to the study drug, or excipients as described in the protocol (to
date there are no known FDA approved drugs chemically related to GSK2118436).

- Pregnant or lactating female.

- Unwillingness or inability to follow the procedures outlined in the protocol.

- Subjects with known glucose 6 phosphate dehydrogenase (G6PD) deficiency.

- Patients positive for HPV. Entry on study allowed only at the discretion of subject
and investigator after informed consent regarding discussion of the risk of
papillomavirus infection. If enrolled, these subjects must use condoms for sexual
activity, regardless of the use of other contraceptive measures and childbearing
status.

- Prior treatment with a BRAF or MEK inhibitor unless approved by the GSK medical
monitor.

Summary
Brief 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.
