Subjects With Treatment Emergent Adverse Events
20 participants

PRIMARY outcome

Timeframe: From first study medication to on Day 31 (after repeated 28 days medication from Day 4 to 31)

Population: DLT evaluated subjects who had achieved ≧75% study drug compliance during a 4-week (28-day) treatment period starting from Day 4. No statistical analysis provided for Subjects With DLTs.

DLT was defined as adverse events occurring during Cycle 1 and: (1) Grade 3 or higher nausea, vomiting, or diarrhea despite the use of anti-emetic or antidiarrheal drugs, (2) Grade 3 or higher non-hematologic toxicity, excluding alopecia, (3) AEs requiring interruption of the IMP for a total of 8 days or longer, (4) Grade 4 neutropenia lasting ≥ 8 days (not applicable for leukemia), (5) Grade 3 or higher febrile neutropenia or infection due to neutropenia (not applicable for leukemia), (6) Grade 4 thrombocytopenia or Grade 3 thrombocytopenia requiring platelet transfusion (not applicable for leukemia).

SECONDARY outcome

Timeframe: From first dose of study medication to withdrawal examination

Population: Efficacy population included all treated subjects who had received at least 1 dose of study drug. No statistical analysis provided for treatment response.

Assessment of the treatment response was evaluated according to internationally recognized response criteria for multiple myeloma, non-Hodgkin's lymphoma, acute myeloid leukemia, chronic myeloid leukemia. "Response" was defined as at least partial response or partial remission (PR) according to the criteria for efficacy assessment.
