- Subjects With Treatment Emergent Adverse Events [ Time Frame: From first study medication to on Day 31 (after repeated 28 days medication from Day 4 to 31) ]Treatment emergent adverse events observed during outcome measure time frame. A Treatment Emergent Adverse Event was defined as an AE occurring after the start of IMP administration.
- Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs) [ Time Frame: From first study medication to on Day 31 (after repeated 28 days medication from Day 4 to 31) ]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).
- Treatment Response [ Time Frame: From first dose of study medication to withdrawal examination ]
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.
