About
The purpose of this open-label, randomized, 2-treatment, 2-period crossover study with incomplete washout is to evaluate the relative bioavailability of 2mg GSK1120212 pediatric oral solution formulation in comparison to 2mg GSK1120212 tablet formulation, to investigate the safety and tolerability of a single dose of the GSK1120212 pediatric oral solution formulation as compared to a single dose of the GSK1120212 tablet formulation, and to investigate the palatability of the GSK1120212 pediatric oral solution formulation.
Subjects will be assigned to one of two possible treatment sequences according to the randomization code provided to the sites by GSK: a single dose of 2mg GSK1120212 pediatric oral solution formulation then a single dose of 2mg GSK1120212 tablet formulation, or a single dose of 2mg GSK1120212 tablet formulation, then a single dose of 2mg GSK1120212 pediatric oral solution formulation. Administration of GSK1120212 in either sequence will be followed by 7 days of serial blood sampling for pharmacokinetic analysis of plasma GSK1120212. Safety assessments, including assessment of adverse events, clinical laboratory values (hematology, clinical chemistry and urinalysis) and vital signs, will be made throughout the study. After completing the pharmacokinetic assessments for two periods, eligible subjects may transition to MEK114375, an open-label rollover study of GSK1120212.

- Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study medication until 16 weeks after the last dose of GSK1120212.
Exclusion criteria
- Currently receiving cancer therapy (e.g., chemotherapy with delayed toxicity, extensive radiation therapy, immunotherapy, biologic therapy, or major surgery) within 3 weeks prior to randomization; chemotherapy regimens without delayed toxicity within 2 weeks prior to randomization; or use of an investigational anti-cancer drug within 4 weeks prior to randomization.
- Unresolved Grade 2 or greater toxicity (based on NCI-CTCAE, version 4.0, 2009) from previous anti-cancer therapy except Grade 2 decreased haemoglobin levels or alopecia.
- Pre-existing peripheral neuropathy >= Grade 2.
- Has participated in a clinical trial and received investigational product within 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product, whichever is longer, prior to the first dose of investigational product in this study.
- Has participated in a clinical trial that resulted in or made a donation of blood or blood products in excess of 500mL within 56 days of the first dose of investigational product in this study.
- Has presence of active GI disease or other condition (e.g., gastrectomy, bariatric surgery, small or large bowel resection, or cholecystectomy) that may interfere significantly with absorption of drugs.
- Any serious and/or unstable pre-existing medical (aside from malignancy exception above), psychiatric disorder, or other conditions that could interfere with subject's safety, obtaining informed consent or compliance with the study procedures, in the opinion of the investigator or the GSK medical monitor.
- History of interstitial lung disease or pneumonitis.
