An event was considered DLT if it occurred within first 3weeks of treatment \& met one of following criteria:unless it was clearly established that event is unrelated to treatment:Grade4 neutropenia persisting for \>=7 days/febrile neutropenia not responding to treatment within 24hours, Grade4 thrombocytopenia lasting more than 7day \& not responding to transfusions/Grade3 thrombocytopenia associated with bleeding (\>10milliliter \[mL\]), Drug-related Grade 3/4 non-hematologic toxicity as described in National Cancer Institute-Common Terminology Criteria for Adverse Events(NCI-CTCAE)version 4.0, Drug-related Grade2 non-hematological toxicity, Grade2 Troponin T elevation(central laboratory\>Upper Limit of Normal\[ULN\]),measured on two separate occasions within 48 hours, Treatment delay of 14 days/greater due to unresolved drug-related toxicity,ALT\>=3xULN+bilirubin\>=2xULN(\>35% direct)/Alanine aminotransferase(ALT) between 3-5xULN with bilirubin\<2xULN but with hepatitis symptom/rash/ALT\>=5xULN.

Part 1: Number of Participants With Worst-case Post-Baseline Abnormal Electrocardiogram (ECG) Findings (Investigator Reading)

时间窗: Up to 86.9 weeks

12-lead ECGs were recorded with the participants in a supine position using an ECG machine. Number of participants with worst-case clinically significant and not clinically significant abnormal ECG findings have been presented. Clinically significant abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.

Part 1: Number of Participants With Non-serious Adverse Events (AEs) and Serious Adverse Events (SAEs) and AE Leading to Discontinuation (AELD)

时间窗: Up to 86.9 weeks

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and SAE is defined as any untoward medical occurrence that, at any dose which results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or, is a congenital anomaly/birth defect. AELD is adverse events leading to permanent discontinuation of study treatment.

Part 1: Number of Participants With Dose Reductions

时间窗: Up to 86.9 weeks

Number of participants with dose reductions due to any reason is presented.

Part 1: Number of Participants With Any Dose Interruptions or Delays

时间窗: Up to 86.9 weeks

Number of participants with any dose interruptions/ delays is presented.

Part 1: Number of Participants With Grade Change From Baseline in Clinical Chemistry Parameters

时间窗: Up to 86.9 weeks

Blood samples were collected for the analysis of following clinical chemistry parameters: glucose, prothrombin international normalized ratio (Pro. INR), albumin, amylase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, calcium, calcium ionized, cholesterol, creatinine, creatine kinase, lipase, potassium, magnesium, sodium, triglycerides, alkaline phosphatase (ALP). Laboratory parameters were graded according to NCI-CTCAE version 4.0. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences; Grade 5: death related to AE. Higher grade indicates greater severity. An increase was defined as an increase relative to Baseline. Baseline was the most recent, non-missing value prior to or on the first study treatment dose date. Data for worst-case post Baseline with any grade increase is presented.

Part 1: Number of Participants With Worst-case Urinalysis Results Post-Baseline Relative to Baseline by Dipstick Method

时间窗: Up to 86.9 weeks

Urine samples were collected to assess glucose, ketones, occult blood, urine protein, and monoclonal protein (monoclonal pro). The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters were recorded as negative, trace, 1+, 2+, 3+ indicating proportional concentrations in the urine sample. Any increase was defined as any increase in proportional concentrations relative to Baseline. Baseline was the most recent, non-missing value prior to or on the first study treatment dose date. Data for worst-case post Baseline with any increase is presented.

Part 1: Number of Participants With Grade Change From Baseline in Hematology Parameters

时间窗: Up to 86.9 weeks

Blood samples were collected for the analysis of following hematology parameters: hemoglobin, lymphocytes, neutrophils, platelets and leukocytes. The laboratory parameters were graded according to NCI-CTCAE version 4.0. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences; Grade 5: death related to AE. Higher grade indicates greater severity. An increase is defined as an increase in CTCAE grade relative to Baseline grade. Baseline was the most recent, non-missing value prior to or on the first study treatment dose date. Data for worst-case post Baseline with any grade increase is presented.

Part 1: Number of Participants With Worst Case Vital Signs Results Relative to Baseline: Pulse Rate and Body Temperature

时间窗: Up to 86.9 weeks

Vital signs (pulse rate and temperature) were measured after resting for at least 5 minutes in a supine or semi-recumbent position. The clinical concern ranges were: For pulse rate (low \<60 beats per minute \[bpm\] and high \>100 bpm); For body temperature (\<=35 degrees Celsius or \>=38 degrees Celsius). Participants were counted in the worst case category that their value changed to (low, normal or high), unless there was no change in their category. Participants whose value category was unchanged, or whose value became normal, were recorded in the "To Normal or No Change" category. Participants were counted twice if the participant had values that changed "To Low" and "To High", so the percentages may not add to 100%. Baseline was the most recent, non-missing value prior to or on the first study treatment dose date.

Part 1: Number of Participants With Increase to Grade 3 From Baseline in Vital Signs: Diastolic Blood Pressure (DBP) and Systolic Blood Pressure (SBP)

时间窗: Up to 86.9 weeks

DBP and SBP were measured after resting for at least 5 minutes in a supine or semi-recumbent position. They were graded according to NCI-CTCAE version 4.0. For SBP: Grade 0 (\<=120 millimeter of mercury \[mmHg\]), Grade 1 (121-139 mmHg), Grade 2 (140-159 mmHg), Grade 3 (\>=160 mmHg). For DBP: Grade 0 (\<=80 mmHg), Grade 1 (81-89 mmHg), Grade 2 (90-99 mmHg), Grade 3 (\>=100 mmHg). Higher grade indicates greater severity. Baseline was the most recent, non-missing value prior to or on the first study treatment dose date. An increase is defined as an increase in grade relative to Baseline grade. Number of participants with increase to Grade 3 from Baseline is presented.

Part 2: Objective Response Rate Lasting at Least 4 Months (ORR4) (CTCL Cohorts)

时间窗: Up to 36.4 weeks

ORR4 for CTCL cohorts is defined as the percentage of participants that have achieved a CR or PR lasting at least 4 months per global response criteria and the modified severity weighted assessment tool (mSWAT). ORR4 and 95% exact confidence interval is presented.

Part 2: Objective Response Rate (ORR) (MDS Cohort)

时间窗: Up to 36.4 weeks

ORR for MDS cohort is defined as the percentage of participants achieving Complete Response (CR), Marrow CR, CRp (as per CR but platelet count \<100 x 10\^9 cells/Liter\[L\]), CRi (as per CR but platelet count \<100 x 10\^9cells/L or neutrophil count \<1 x 10\^9 cells/L), or Partial Response (PR) per response criteria. Complete response is defined as bone marrow \<=5% myeloblasts with normal maturation of all cell lines, with hemoglobin concentration of \>=11 grams per deciliter (g/dL), absolute neutrophil count \>=1 x 10\^9 cells/L, platelet count \>=100x10\^9 cells/L and 0% blasts in the peripheral blood. Marrow CR is defined as Bone marrow \<=5% myeloblasts and decrease by \>=50% over pre-treatment. Objective response rate was determined by the investigator according to international myeloma working group (IMWG) response criteria.
