Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part 2: Percentage of Participants With Objective Tumor Response (Response Rate)	Response using Response Evaluation Criteria In Solid Tumors (RECIST). Complete Response (CR)=disappearance of all target lesions; Partial Response (PR)=30% decrease in sum of longest diameter of target lesions; Progressive Disease (PD)=20% increase in sum of longest diameter of target lesions; Stable Disease (SD)=small changes that do not meet above criteria. Objective response rate (%)=number of objective responders divided by the number of participants qualified for efficacy analysis *100, where objective responders are those participants who have met criteria either for CR or PR.	Baseline up to 3 years
Secondary	Percentage of Participants Exhibiting a Decline in Prostate-Specific Androgen (PSA) From Baseline =30% Within First 3 Months of Treatment	PSA is a protein produced by the cells of the prostate gland. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer and in other prostate disorders. A blood test to measure PSA is considered the most effective test currently available for the early detection of prostate cancer. Decline in PSA of =30% from baseline within the first 3 months of treatment was calculated.	Baseline up to 3 months
Secondary	Prostate-Specific Androgen (PSA) Velocity at 2 Months	PSA is a protein produced by the cells of the prostate gland. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer and in other prostate disorders. A blood test to measure PSA is considered the most effective test currently available for the early detection of prostate cancer. PSA velocity is computed for each participant by means of linear regression on the logarithm of PSA. The linear regression fits a line through the logarithm of the PSA value on the y-axis, and the time from baseline on the x-axis with the baseline PSA value at time zero. The resulting slope is PSA velocity.	Baseline up to 2 months
Secondary	Prostate-Specific Androgen (PSA) Velocity at 3 Months	PSA is a protein produced by the cells of the prostate gland. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer and in other prostate disorders. A blood test to measure PSA is considered the most effective test currently available for the early detection of prostate cancer. PSA velocity is computed for each participant by means of linear regression on the logarithm of PSA. The linear regression fits a line through the logarithm of the PSA value on the y-axis, and the time from baseline on the x-axis with the baseline PSA value at time zero. The resulting slope is PSA velocity.	Baseline up to 3 months
Secondary	Part 2: Progression Free Survival (PFS)	PFS was defined as the time from the date of study enrollment to the first date of objectively determined progressive disease (PD) or death from any cause. PD was determined using Response Evaluation Criteria In Solid Tumors (RECIST version 1.0). PD is =20% increase in the sum of the longest diameter (LD) of target lesions taking as references the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions. For participants not known to have died and who did not have PD, PFS was censored at the date of the last progression-free assessment. For participants who received subsequent systemic anticancer therapy (after discontinuation from the study treatment) prior to disease progression or death, PFS was censored at the date of last progression-free assessment prior to the initiation of post-discontinuation systemic anticancer therapy. No participant completed a full cycle of therapy and thus no formal analysis was performed.	Baseline to measured PD (up to 487 days)
Secondary	Part 2: Overall Survival (OS)	Overall survival (OS) time is defined as the time from the date of diagnosis to the date of death from any cause. For participants who are still alive at the time of analysis, survival time will be censored at the last contact date.	Baseline to death (up to 642 days)
Secondary	Part 2: Duration of Response	Duration of response is defined as the time from date of objective response to progressive disease (PD) or death or prostate-specific androgen (PSA) returning to at least 50% from original baseline value.	First objective response to PD/death/PSA returning to 50% or more than the original baseline value (up to 616 days)
Secondary	Number of Participants With Adverse Events (AEs)	A listing of serious AEs (SAEs) and all other non-serious AEs is included in the Reported Adverse Event Module.	Baseline through 3 years
Secondary	Part I: Pharmacokinetic (PK) Parameter: Maximum Observed Drug Concentration During a Dosing Interval at Steady State (Cmax,ss) of Enzastaurin, LSN326020, and Total Analyte (Enzastaurin + LSN326020)	Cmax,ss was calculated using concentration versus time data of enzastaurin, LSN326020, and total analyte (enzastaurin + LSN326020). Data are reported as Geometric Mean and Geometric Coefficient of Variation (%).	Part 1: Cycle 1, Day 21 - predose 2, 4, 6, 8, and 24 hours postdose; Cycle 2, Day 1 - predose, 2, 3, 4, 8, and 24 hours postdose
Secondary	Pharmacokinetic (PK) Parameter: Area Under the Concentration Versus Time Curve During 1 Dosing Interval at Steady State (AUCt,ss) of Enzastaurin, LSN326020, and Total Analyte (Enzastaurin + LSN326020)	AUCt,ss was calculated using concentration versus time data of enzastaurin, LSN326020, and total analyte (enzastaurin + LSN326020). Data are reported as Geometric Mean and Geometric Coefficient of Variation (%).	Part 1: Cycle 1, Day 21 - predose 2, 4, 6, 8, and 24 hours postdose; Cycle 2, Day 1 - predose, 2, 3, 4, 8, and 24 hours postdose; Part 2: Cycle 2, Day 1 - predose, 1-3, and 4-9 hours postdose
Secondary	Pharmacokinetic (PK) Parameter: Maximum Plasma Concentration (Cmax) of Docetaxel	Cmax was calculated using concentration versus time data of docetaxel. Data are reported as Geometric Mean and Geometric Coefficient of Variation (%).	Part 1: Cycle 1, Day 1 - predose 0.5, 1, 1.5, 2, 3, 4, 8, and 24 hours postdose; Cycle 2, Day 1 - predose, 0.5, 1, 1.5, 2, 3, 4, 8, and 24 hours postdose
Secondary	Pharmacokinetic (PK) Parameter: Area Under the Plasma Concentration Time Curve From Time Zero to Infinity (AUC[0-8]) of Docetaxel	AUC(0-8) was calculated using concentration versus time data of docetaxel. Data are reported as Geometric Mean and Geometric Coefficient of Variation (%).	Part 1: Cycle 1, Day 1 - predose 0.5, 1, 1.5, 2, 3, 4, 8, and 24 hours postdose; Cycle 2, Day 1 - predose, 0.5, 1, 1.5, 2, 3, 4, 8, and 24 hours postdose
Secondary	Tumor Markers	Pharmacogenomic (PGx) work on S032 was cancelled due to the limited number of tissue samples collected and the lack of clinical efficacy (responders) to enzastaurin. Potential biomarkers would have been assessed by dividing participants into low and high expression classes.	Baseline up to 36 months
