Combination 1: Part 1: Number of Participants With Specified Toxicity |
Number of participants with specified toxicity during Cycle 1 was reported. Only toxicities that occurred during safety evaluation period(defined as first 28 days of treatment-Cycle 1 of Part 1) was used for analysis of specified toxicities and for dose reduction decisions. Toxicities were graded for severity as per NCI-CTCAE, version 4.03. Safety evaluation criteria were: Any Grade(G) >=3 non-hematological toxicity without anorexia, or constipation, fatigue improved to G<=2 in <7 days, vomiting and diarrhea resolved in <=3 days, laboratory abnormalities with hospitalization, tumor flare improved to G<=2 in <=7 days, elevation in AST/ALT for <=7 days and G3 hypertension controlled by medical therapy; any treatment-related(TR)G4 or G>=3 thrombocytopenia required platelet transfusion; Any TR G4 neutropenia >=7 days or G3 or 4 neutropenia with infection/fever >38.5 degrees Celsius; Any TR SAE or intolerable toxicity. |

Combination 1: Part 2: Objective Response Rate (ORR) |
ORR of soft tissue (visceral or nodal disease) was defined as percentage of participants with measurable disease who achieved a best response of either complete response (CR) or partial response (PR) as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 with no evidence of bone progression according to prostate cancer working group 3 (PCWG3) criteria. |
Up to 37 months |
|
| Primary |
Combination 2: Composite Response Rate (RR) |
Composite response rate was defined as the percentage of participants who had a composite response which is defined as one of the following PCWG3 criteria: Objective response (percentage of participants with measurable disease who achieved a best response of either CR or PR as assessed by RECIST 1.1 with no evidence of bone progression according to PCWG3 criteria) (confirmed per RECIST 1.1), or; circulating tumor cells (CTC) response: defined as CTC=0 per 7.5 milliliters (mL) of blood at 8 weeks for participants who had CTC greater than or equal to (>=) 1 at baseline or CTC less than (<) 5 per 7.5 mL with CTC >=5 at baseline, confirmed by a second consecutive value obtained 4 or more weeks later, or prostate-specific antigen (PSA) declined of >=50 percentage (%), measured twice 3 to 4 weeks apart. This outcome measure was analyzed for specified arms only as pre-planned in the protocol. |

Combination 1: Part 2: Number of Participants With Adverse Events (AEs) |
AE was defined as an any untoward medical occurrence in a clinical study subject administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. |
Up to 37 months |
|
| Primary |
Combination 2: Number of Participants With Adverse Events (AEs) |
AE was defined as an any untoward medical occurrence in a clinical study subject administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. |

| Primary |
Combination 1: Part 2: Number of Participants With Adverse Events (AEs) of Grade >=3 Severity |
AE was defined as an any untoward medical occurrence in a clinical study subject administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An assessment of severity grade was made using the National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) as Grade 1 (mild): awareness of symptoms that are easily tolerated, causing minimal discomfort and not interfering with everyday activities; Grade 2 (moderate): sufficient discomfort is present to cause interference with normal activity; Grade 3 (severe): extreme distress, causing significant impairment of functioning or incapacitation, prevents normal everyday activities; Grade 4 (Life-threatening): urgent intervention indicated; and Grade 5 (death). |
