What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Required Study Drug Dose Reduction During Treatment Periods 1 and 2
Time Frame: Treatment Period 1 (Day 1) up to end of Treatment Period 2 (42 days)
Percentage of participants that required dose reductions of Docetaxel and Enzalutamide treatment were reported in this outcome measure. Dose modifications (interruptions or dose reductions) were permitted for participants who had adverse events that were intolerable or could not be improved by other means. Dose reductions or delays were determined according to the prescribing information and at the discretion of the investigator.
Treatment Period 1 (Day 1) up to end of Treatment Period 2 (42 days)
Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (AE)
Time Frame: Treatment Period 1 (Day 1) up to end of study treatment (maximum 70 months)
AE was any untoward medical occurrence in participant who received study drug without regard to possibility of causal relationship. Percentage of participants that discontinued study drug due to adverse events were reported in this outcome measure.
Treatment Period 1 (Day 1) up to end of study treatment (maximum 70 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
