Brief Summary

This is an open-label, multi-center, dose-escalation trial of pimasertib (MSC1936369B) in blood and bone marrow cancers. The trial will be conducted in two parts:

Part 1 (safety run-in period): Will determine the maximum tolerated dose (MTD) of the study drug in subjects with advanced hematological malignancies.

Part 2: Will assess the anti-leukemic activity of the study drug in older subjects with newly diagnosed poor prognosis acute myeloid leukemia (AML) who are not candidates for intensive chemotherapy.

Primary Outcome Measures
NameTimeMethod
Part 1: Number of Subjects With Dose Limiting Toxicities (DLTs)Baseline Up to Day 29 of Cycle 1

The DLT was any toxicity that resulted in treatment delay for more than (\>) 2 weeks due to treatment-related adverse effects, or any Grade greater than or equal to (\>=) 3 non-hematological toxicity excluding Grade 4 asymptomatic increases in liver function tests reversible within 7 days in subjects with liver involvement, and Grade 3 asymptomatic increases in liver function tests reversible within 7 days for subjects without liver involvement, Grade 3 vomiting unless encountered and persistent for more than 3 days despite adequate and optimal therapy, and Grade 3 diarrhea unless encountered and persistent for more than 3 days despite adequate and optimal anti-diarrhea therapy at any DL and judged to be possibly or probably related to the trial treatment by the Investigator and/or the Sponsor.

Part 2: Percentage of Subjects With Best Overall ResponseDay 29 of every 29-day cycle until progression reported between day of first subject randomized, September 2009, until cut-off date, December 2012

The best overall response was to be reported as either of the following: (1) Morphologic complete remission (CR) = normalization of the peripheral blood absolute neutrophil count (PBANC) \>1.0x10\^9 per liter (/L), platelets \>100x10\^9 /L, bone marrow aspirate with less than or equal to (\<=) 5 percent (%) blasts, no blasts with Auer rods (AML only). (2) Complete remission with incomplete blood count recovery (CRi) = Same as CR without normalization of PBANC and platelet count. (3) Partial remission (PR) = normalization of PBANC \>1.0x10\^9/L, platelets \>100x10\^9/L, and at least a 50% decrease in the percentage of marrow aspirate blasts to 5-25%, or marrow blasts less than (\<) 5%. (4) Progressive disease (PD) = \>50% increase in peripheral blood or bone marrow blasts. (5) Stable disease (SD) = subjects who failed to achieve CR, CRi or PR and without criteria for PD.
