Tidsramme: Stage 1 and 1A: Days 1 to 28 of Cycle 1
|
Adverse events (AE) were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v3.0. DLT was defined as either of the following occurring during the Study Treatment Period. The occurrence of a drug-related AE that, in the opinion of the cohort review committee (CRC), was of potential clinical significance such that further dose escalation would expose participants in higher dose cohorts to risk of irreversible medical harm or require medical treatment to avoid irreversible medical harm or non-hematologic toxicity

A DLT was defined as either of the following occurring during the Study Treatment Period: Occurrence of a drug-related AE that, in the opinion of the CRC, was of potential clinical significance such that further dose escalation would expose participants to risk of irreversible medical harm; Nonhematologic toxicity: Grade 3 or 4 events, including Grade 3 nausea and/or vomiting and/or Grade 3 diarrhea, despite prophylaxis and/or treatment; Hematologic toxicity: Grade 4 thrombocytopenia. Grade 4 neutropenia of more than 4 days' duration; Grade 4 neutropenia of any duration with fever or documented infection.
