Primary Outcome Measures :
  1. Part A: Number of Participants With Dose-limiting Toxicities (DLTs) [ Time Frame: From treatment initiation until Day 28 ]
    DLTs were defined as treatment-related adverse events (AEs) that occurred within the first 28 days of treatment as per common terminology criteria for adverse events (CTCAE) version 4.03: any grade 3 or higher toxicity; QT/Fridericia corrected QT (QTcF) greater than (>) 500 millisecond (msec) after treatment initiation; QT/QTcF interval prolongation >60 msec postdose.

  2. Part A: Number of Participants Reporting One or More Treatment-emergent Adverse Event (TEAE) [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 68) ]
  3. Part A: Number of Participants With Grade 2 or Higher Laboratory Test Abnormalities [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 68) ]
    Laboratory test abnormalities were graded using the CTCAE. The grades were: Grade 2- (moderate) minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activity of daily living (ADL); Grade 3- (severe) medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limited self-care ADL. Data has been presented for any Grade 2 or higher event in the laboratory test abnormalities.

  4. Part A: Number of Participants With Markedly Abnormal Values of Vital Signs Parameters [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 68) ]
  5. Part A: Number of Participants With Markedly Abnormal Values of Electrocardiogram (ECG) Parameters [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 68) ]
  6. Part B: Number of Participants Reporting One or More TEAE [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 712) ]
  7. Part B: Number of Participants With Grade 2 or Higher Laboratory Test Abnormalities [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 712) ]
    Laboratory test abnormalities were graded using the CTCAE. The grades were: Grade 2- (moderate) minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL; Grade 3- (severe) medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limited self-care ADL. Data has been presented for any Grade 2 or higher event in the laboratory test abnormalities. Here aspartate aminotransferase (AST) (glutamic-oxaloacetic transaminase [GOT]) High, creatine kinase (CK) (creatine phosphokinase [CPK]) High, prothrombin time (PT)-international normalized ratio (INR) High.

  8. Part B: Number of Participants With Markedly Abnormal Values of Vital Signs Parameters [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 712) ]
    Here "BP" is blood pressure.

  9. Part B: Number of Participants With Markedly Abnormal Values of ECG Parameters [ Time Frame: From treatment initiation until 40 days after last dose of study drug (Day 712) ]

Secondary Outcome Measures :
  1. Part A: Cmax: Maximum Observed Plasma Concentration for Unchanged TAK-385 on Day 1, 14 and 28 [ Time Frame: Days 1, 14 and 28 pre-dose and at multiple time points (up to 12 hours for Days 1 and 14; up to 72 hours for Day 28) post-dose ]
  2. Part A: AUCτ: Area Under the Plasma Concentration-time Curve From Time 0 to (Tau) Over the Dosing Interval for Unchanged TAK-385 on Day 1, 14 and 28 [ Time Frame: Days 1, 14 and 28 pre-dose and at multiple time points (up to 12 hours for Days 1 and 14; up to 72 hours for Day 28) post-dose ]
