What was measured

DLT was 1 of the following adverse events likely related to abemaciclib/combination and fulfils any 1 of the following criteria graded per National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0: * Any non-hematologic Grade (G) ≥3 toxicity, except: * G3 diarrhea lasting \<72 hour (h) * Acute irinotecan-associated diarrhea lasting \<7 days * G≥3 nausea, vomiting, constipation that lasts \<72 h * G3 mucositis/stomatitis lasting \<72 h * G3 fever/infection * G≥3 electrolyte abnormality that lasts \<72 h, is not complicated, and resolves spontaneously or responds to conventional medication; * G≥3 amylase/lipase that is not associated with symptoms/clinical manifestations of pancreatitis; or * AST/ALT elevation resolving to eligibility criteria within 7 days; * Hematologic toxicities considered a DLT: * A \>14-day Cycle 2 delay due to neutropenia/thrombocytopenia * G≥3 thrombocytopenia with significant bleeding; or * G≥ 4 neutropenic fever

Analysis population: All participants in Part A who received at least one dose of the study drug and had evaluable data for this outcome.

Groups in this outcome

Part A Cohort A1

Participants received: * Abemaciclib: 70 mg/m², administered orally twice daily (BID). * Irinotecan: 50 mg/m²/day, administered IV on Days 1-5 of each cycle. * Temozolomide: 100 mg/m²/day, administered orally on Days 1-5 of each cycle. Treatment continued until progressive disease, a discontinuation criterion, or unacceptable toxicity. Each cycle lasted 21 days.

Part A Cohort A-1

Participants received: * Abemaciclib: 55 mg/m², administered orally BID. * Irinotecan: 50 mg/m²/day, administered IV on Days 1-5 of each cycle. * Temozolomide: 100 mg/m²/day, administered orally on Days 1-5 of each cycle. Treatment continued until progressive disease, a discontinuation criterion, or unacceptable toxicity. Each cycle lasted 21 days.
