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.

Arms:
arm 1: None arm 2: None arm 3: None arm 4: None arm 5: None

Interventions: intervention 1: Pimasertib intervention 2: Pimasertib intervention 3: Pimasertib intervention 4: Pimasertib intervention 5: Pimasertib
Intervention descriptions: intervention 1: Pimasertib will be administered orally at a dose of 8 mg twice daily (BID) on Days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 of a 28-day cycle. The dose will be escalated to 15 mg BID, 23 mg BID, 30 mg BID, 42 mg BID, 60 mg BID, and 75 mg BID) until Maximum Tolerated Dose (MTD) is reached. The treatment will be continued until disease progression, intolerable toxicity, or Investigator/subject decision. intervention 2: Pimasertib will be administered orally at a dose of 8 mg BID on Days 1 to 21 of a 28-day cycle. The dose will be escalated to 15 mg BID, 23 mg BID, 30 mg BID, 42 mg BID, 45 mg BID, 60 mg BID, 75 mg BID, and 90 mg BID until MTD is reached. The treatment will be continued until disease progression, intolerable toxicity, or Investigator/subject decision. intervention 3: Pimasertib will be administered orally at a dose of 60 mg BID on Days 1-28 of a 28-day cycle. The dose escalation will proceed to 75 mg BID until MTD is reached. The treatment will be continued until disease progression, intolerable toxicity, or Investigator/subject decision. intervention 4: Pimasertib will be administered orally twice daily on Days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 of a 28-day cycle. Dose will be determined by Part 1 of the trial (could be the MTD or lower dose level). The treatment will be continued until disease progression, intolerable toxicity, or Investigator/subject decision. intervention 5: Pimasertib will be administered orally twice daily on Days 1 to 21 of a 28-day cycle. Dose will be determined by Part 1 of the trial (could be the MTD or lower dose level). The treatment will be continued until disease progression, intolerable toxicity, or Investigator/subject decision.
