Primary Outcome Measures :
- Non-progression Rate (NPR) at 18 Weeks [ Time Frame: At Week 18 ]NPR was defined as the percentage of participants with complete response (CR), partial response (PR) or stable disease (SD) as assessed by the Investigator according to Response Evaluation Criteria in Solid Tumors (RECIST), v1.1 or for malignant pleural mesothelioma according to Malignant Pleural Mesothelioma Response Evaluation Criteria. CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of the diameters of all target and all new measurable lesions in the absence of CR. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions. For prostate cancer according to Prostate Response Evaluation Criteria. CR: PSA <5 ng/ml measured twice at least 3 weeks apart or PSA response: PSA < 50% of the PSA reference value occurring at any time after treatment was initiated.

CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of the diameters of all target and all new measurable lesions in the absence of CR. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions. For prostate cancer according to Prostate Response Evaluation Criteria. CR: PSA <5 ng/ml measured twice at least 3 weeks apart or PSA response: PSA < 50% of the PSA reference value occurring at any time after treatment was initiated.

CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of the diameters of all target and all new measurable lesions, taking as reference the baseline sum of diameters, in the absence of CR. For prostate cancer according to Prostate Response Evaluation Criteria. CR: PSA <5 ng/ml measured twice at least 3 weeks apart or PSA response: PSA < 50% of the PSA reference value occurring at any time after treatment was initiated.

For an individual participant BOR was obtained as follows: 1) CR: overall tumor response assessment of CR at 2 consecutive visits at least 28 days apart. 2) PR: overall tumor response assessment of PR or CR at 2 consecutive visits at least 28 days apart without being a CR. 3) SD: overall tumor response assessment of SD, PR, or CR at one or more visits at least 42 days after start of study treatment, but was not a confirmed CR or PR. 4) PD: an overall tumor response assessment of PD at any visit, and did not meet the criteria for a BOR of CR, PR or SD. 5) Missing: an assessment of SD, PR or CR in the first 42 days after start of study treatment and no further tumor assessments thereafter.
- Clinical Benefit Rate (CBR) [ Time Frame: Baseline up to 4.5 years (assessed every 6 weeks for first 24 weeks and thereafter every 12 weeks up to loss of clinical benefit, withdrawal of consent, death, or study termination by the Sponsor, whichever occurs first) ]CBR was defined as the percentage of participants with CR, PR, or SD according to RECIST v1.1, Malignant Pleural Mesothelioma Response Evaluation Criteria or Prostate Response Evaluation Criteria lasting for >/=6 weeks. CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of the diameters of all target and all new measurable lesions in the absence of CR. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions. For prostate cancer: CR: PSA <5 ng/ml measured twice at least 3 weeks apart or PSA response: PSA < 50% of the PSA reference value occurring at any time after treatment was initiated.
- Duration of Objective Response (DOR) [ Time Frame: Baseline up to 4.5 years (assessed every 6 weeks for first 24 weeks and thereafter every 12 weeks up to loss of clinical benefit, withdrawal of consent, death, or study termination by the Sponsor, whichever occurs first) ]DOR, based on RECIST v1.1, was defined as the time from the first occurrence of a documented objective response (CR or PR) to the time of progression or death from any cause, whichever occurred first. CR: Disappearance of all target lesions. PR: At least a 30% decrease in the sum of the diameters of all target and all new measurable lesions in the absence of CR. PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions. As pre-specified in the Statistical Analysis Plan (SAP) DOR was not analyzed if there were less than 4 participants available for the analysis.
- Progression-Free Survival (PFS) [ Time Frame: Baseline up to 4.5 years (assessed every 6 weeks for first 24 weeks and thereafter every 12 weeks up to loss of clinical benefit, withdrawal of consent, death, or study termination by the Sponsor, whichever occurs first) ]PFS, based on RECIST v1.1, was defined as the time from the first day of study treatment to the first occurrence of disease progression or death from any cause, whichever occurred first. PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions.
- Time to Progression (TTP) [ Time Frame: Baseline up to 4.5 years (assessed every 6 weeks for first 24 weeks and thereafter every 12 weeks up to loss of clinical benefit, withdrawal of consent, death, or study termination by the Sponsor, whichever occurs first) ]Time to progression (TTP), based on RECIST v1.1, was defined as time from the first day of study treatment to the first occurrence of progressive disease or death due to disease progression, whichever occurred first. PD: At least a 20% increase in the sum of diameters of all target and all new measurable lesions.
- Overall Survival (OS) [ Time Frame: Baseline until death due to any cause (up to 4.5 years) ]OS was defined as the time from the first day of study treatment to death from any cause.
- Number of Participants With Adverse Events [ Time Frame: Baseline up to 4.5 years ]An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
