Trial of MSC1936369B in Subjects With Solid Tumors

A Multicenter, Open Label, Phase I Trial of the MEK Inhibitor MSC1936369B Given Orally to Subjects With Solid Tumours

Area Under the Concentration Time Curve Extrapolated From Last Observation to Infinity Given as Percentage of AUC 0-∞ (AUC Extra): Regimen 2 (With Food Effect)	AUCextra was defined as a percentage of AUC0-inf obtained by extrapolation: AUCextra = (1- [AUC0-t / AUC0-inf])*100. AUCextra was reported in terms of percentage of AUC0-inf. Summarized data over Day 1 and Day 2 was reported.	Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 6, 8, 12 and 24 hours post-dose on Cycle 1 Day 1 and Day 2
Area Under the Concentration Time Curve Extrapolated From Last Observation to Infinity Given as Percentage of AUC 0-∞ (AUC Extra): Regimen 3 Once Daily	AUCextra was defined as a percentage of AUC0-inf obtained by extrapolation: AUCextra = (1- [AUC0-t / AUC0-inf])*100. AUCextra was reported in terms of percentage of AUC0-inf.	Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 6, 8 and 24 hours post-dose on Cycle 1 Day 1, Cycle 1 Day 15 and Cycle 3 Day 1
Area Under the Concentration Time Curve Extrapolated From Last Observation to Infinity Given as Percentage of AUC 0-∞ (AUC Extra): Regimen 3 Twice Daily	AUCextra was defined as a percentage of AUC0-inf obtained by extrapolation: AUCextra = (1- [AUC0-t / AUC0-inf])*100. AUCextra was reported in terms of percentage of AUC0-inf.	Pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 6, 8, and 10 h post-dose on Cycle 1 Day 1 and Day 15; pre-dose, 0.5, 1, 1.5, 2, 2.5, 4, 6, 8 h post dose on Cycle 3 Day 1
Phosphorylated Extra-Cellular Signal-Regulated Kinase (pERK) Fold Change in Peripheral Blood Monocyte Cells (PBMC) and Tot ERK Fold Change in Peripheral Blood Monocyte Cells (PBMC)		Pre-dose on C1D1, C1D2, C1D5, C1D8; 2, 4, 8 h post-dose on C1D1; pre-dose, 2, 8, 24 h post-dose on C1D12-15; pre-dose, 2, 4 h post-dose on C1D3
Number of Subjects With Clinical Benefit (Complete Response [CR], Partial Response [PR] or Stable Disease [SD}) and Progressive Disease (PD) Based on the Best Overall Response (BOR)	Number of subjects with clinical benefit (CR, PR, or SD) and PD according to Response Evaluation Criteria in Solid Tumors (RECIST Version 1.0) was reported. CR: defined as disappearance of all target and all non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR: defined as at least a 30% decrease in sum of longest diameter of target lesions, taking as reference the baseline sum of longest diameter. PD:defined as at least a 20% increase in sum of longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study) or unequivocal progression of existing non-target lesions. SD: defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of longest diameter while on study.	Baseline until disease progression (assessed up to end of treatment [253 weeks])
