Purpose:

GSK2118436 is an orally administered, potent and selective small molecule BRAF inhibitor that is currently being developed for the treatment of BRAF mutation-positive tumors. This is an open-label, non-randomized study designed to determine the absolute bioavailability of an oral dose of 150 mg of GSK2118436 co-administered with an intravenous 50 microgram dose of [14C]GSK2118436 in subjects with BRAF mutant solid tumors. Pharmacokinetic samples will be obtained up to 72 hours post-dose. Safety assessments will be performed throughout the study. After completing all assessments, eligible subjects may transition to BRF114144, an open-label, rollover study of GSK2118436 to continue treatment.

If clarification is needed as to whether a condition will significantly affect absorption of drugs, contact the GSK medical monitor for permission to enrol the subject; - A history of known Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection (subjects with documented laboratory evidence of HBV clearance may be enrolled); - Presence of invasive malignancy other than one of the malignancies covered under Inclusion Criterion; subjects with a history of another malignancy that has been definitively treated can be enrolled; - Subjects with brain metastases are excluded if their brain metastases are either: Symptomatic Treated (surgery, radiation therapy), but not clinically and radiographically stable for a period of at least one month prior to study entry, or Asymptomatic and untreated but > 1 cm in the longest dimension Exception: Subjects with small (≤ 1 cm in the longest dimension), asymptomatic brain metastases that do not need immediate local therapy can be enrolled. Subjects on a stable dose of corticosteroids for more than one month, or those who have been off corticosteroids for at least 2 weeks can be enrolled. Subjects must also be off of enzyme-inducing anticonvulsants for more than 4 weeks; - Corrected QT (QTc) interval >/= 480 msecs; - History of acute coronary syndromes (including unstable angina), coronary angioplasty, or stenting within the past 24 weeks; - Class II, III, or IV heart failure as defined by the New York Heart Association (NYHA) functional classification system; abnormal cardiac valve morphology documented by ECHO [subjects with minimal abnormalities (i.e., mild regurgitation/stenosis) can be entered on study - if clarification is needed as to whether an ECHO abnormality is minimal, please contact the GSK medical monitor); or history of known cardiac arrhythmias (except sinus arrythmias) within the past 24 weeks; - Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the study drugs, or excipients (note: to date there are no known drugs chemically related to GSK2118436 which are approved by the FDA); - Uncontrolled medical conditions (e.g., diabetes mellitus, hypertension), psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol; or history of alcohol or drug abuse within 6 months prior to screening; or unwillingness or inability to follow the procedures required in the protocol; - Subjects with known glucose 6 phosphate dehydrogenase (G6PD) deficiency; - Donation of blood or blood products in excess of 500 mL within the 56 days prior to administration of study medication; - Pregnant females as determined by positive β hCG test at screening or prior to dosing or lactating females who are actively breast feeding; - Subject is mentally or legally incapacitated;
