DLTs will be defined as toxicities observed during the first 2 cycles (8 weeks) of Part 1 and include: Grade ≥3 nonhematologic toxicity (except Grade 3 nausea, vomiting, diarrhea, rash, fatigue, and uncontrolled hypertension which will not be considered a DLT unless lasting ≥72 hours despite optimal supportive care); Grade 4 hematologic toxicity lasting >7 days (except Grade 3 lymphocytosis, Grade 4 platelet count decreased of any duration, or Grade 3 platelet count decreased if associated with bleeding); any Grade 3 or Grade 4 nonhematologic laboratory abnormality if values result in drug-induced liver injury, or medical intervention is required, or the abnormality leads to hospitalization, or the abnormality persists for >1 week (with exceptions); missing >25% of nemtabrutinib doses as a result of drug-related adverse events (AEs) during the first 2 cycles (8 weeks); Grade 5 toxicity.
