Study Endpoints
Primary Endpoints
Part 1: Safety assessment as assessed by adverse events (AEs) and serious adverse events (SAEs)

Screening, Day 1, Day 15, Day 22, and every 8 weeks from first dose till post study visit (approximately 21 days from last dose)

Twelve lead ECGs will be obtained to determine the MTD and RP2D combination of GSK2256098 and trametinib.

Part 1: Safety assessment as assessed by vital signs
From Day 1 till post study visit (approximately 21 days from last dose)

Vital sign measurements will include systolic and diastolic blood pressure, pulse rate, and temperature

Part 1: Safety assessment as assessed by change from baseline in laboratory values
From Day 1 till post study visit (approximately 21 days from last dose)

Clinical laboratory assessments will include hematology, clinical chemistry, routine urinalysis and additional parameters

Part 1: Safety assessment as assessed by echocardiogram
Screening, Day 28 and Day 1 of Weeks 13, 21, 33, then every 12 weeks.

Echocardiograms will be performed to assess cardiac ejection fraction.

Part 1: Safety assessment as assessed by eye examination
Screening and as clinically warranted

A standard ophthalmic exam will be performed by an ophthalmologist.

Part 1: Safety assessment as assessed by urine protein to creatinine (UPC) ratio
From Day 1 till post study visit (approximately 21 days from last dose)

Urine samples will be collected for the analyses of UPC ratio.

Part 2: Long term safety assessment as assessed by AEs and SAEs
From Day 1 till post study visit (approximately 21 days from last dose)

AEs and SAEs will be recorded to assess longer term safety of the GSK2256098/trametinib combination at the RP2D in a larger cohort of subjects with MPM.

Part 2: Long term safety assessment as assessed by UPC ratio
From Day 1 till post study visit (approximately 21 days from last dose)

Urine samples will be collected for the analyses of UPC ratio.

To evaluate the Maximum tolerated dose, identify the recommended Phase 2 dose(s), dose limiting toxicities, safety and tolerability of GSK2256098 given orally on consecutive days.
Until disease progression
To characterize the safety of single doses of GSK2256098 in adult healthy subjects
within 10-14 days following administration of study drug
To characterize the single dose pharmacokinetics of GSK2256098 in blood and urine in adult healthy subjects
14 days after administration of study drug
Secondary Endpoints
Part 1: GSK2256098 and trametinib PK assessment following repeat-dose (Day 15) administration of GSK2256098 and trametinib
Day 15 (pre-dose, 1, 1.5, 2, 4, 6, 8 hours)
Part 1: Tumor response and analysis of change from baseline levels of PD markers including pFAK/FAK, and pERK/ERK measured in tumor biopsies
Screening (before the first dose on Day 1), Day 15 and 22
Part 2: Tumor response as measured by modified Response Evaluation Criteria In Solid Tumors (RECIST) for mesothelioma
Screening, Every 8 weeks from first dose and at progression and post study (approximately 21 days from last dose)

Treatment Arms
ArmTypeDescription
Part 1EXPERIMENTALPart 1 will determine the MTD and RP2D based on the safety and tolerability of GSK2256098 administered with trametinib. Subject will be administered starting dose of 1.0 mg OD trametinib combined with 500 mg BID GSK2256098. Dose escalation will continue until the MTD is established.
Part 2EXPERIMENTALBased on determination of combination dose regimen in Part 1, dose expansion cohorts for Part 2 will be opened.
Part 3EXPERIMENTALPart 3 - Characterize the biologically active dose range by analysis of PD markers in skin, hair and in tumor tissue in subjects with solid tumors amendable to biopsy and know to over express FAK
Part 4EXPERIMENTALPart 4 - Explore further the safety, PK, tolerability and anti-tumor activity of GSK2256098 in subjects with relapsed glioblastoma multiforme (GBM).
Part 5EXPERIMENTALPart 5 will investigate the time course, the extent of an apparent change in the PK of GSK2256098 following repeated dosing, and screen for potential CYP3A induction as a possible mechanism of reduced systemic exposure of GSK2256098 at Day 15 and later time points.
Dose Escalation CohortsEXPERIMENTALsingle dose administration escalating doses starting at 20 mg and continue escalation; the highest dose in this study will not exceed the mean Day 1 exposure in male dogs at the NOAEL dose (6 mg/kg/day).
Food effect CohortEXPERIMENTALDose to be selected based on emerging safety and PK data; subjects will be given FDA standard high fat meal followed by single dose of study drug.
