- Primary Outcome Measures
Name Time Method Percentage of Participants With Progression Free Survival (PFS) at 6 Months Baseline to 6 months PFS defined as time from date of first dose of enzastaurin to first date of documented progressive disease (PD) or date of death (any cause), whichever occurred first. Using Response Evaluation Criteria in Solid Tumors (RECIST v1.0) PD defined as ≥20% increase in sum of the longest diameter (LD) of target lesions, taking as reference smallest sum LD recorded since treatment started or appearance of ≥1 new lesions. Participants not known to have died as of data-inclusion cut-off date and who did not have PD, PFS was censored at date of last progression-free disease assessment prior to date of any post discontinuation anticancer therapy. Participants who took any subsequent systemic anticancer therapy prior to PD or death, PFS was censored at date of last progression-free disease assessment prior to the date of any post discontinuation anticancer therapy. PFS at 6 months = participants who were progression free and alive at 6 months divided by the number of treated participants x 100.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Complete Response (CR) or Partial Response (PR) [Objective Response Rate (ORR)] Baseline to measured progressive disease (PD) up to 24 months Objective response rate during treatment was defined as the number of participants with documented complete response (CR) or partial response (PR) divided by the total number of participants. CR and PR defined using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). CR defined as the disappearance of all target and non-target lesions and normalization of tumor marker levels in non-target lesions. PR defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. Percentage of participants with CR or PR (ORR) was the number of participants with documented CR or PR divided by the total number of treated participants x 100.
Change From Baseline in QTc Interval Baseline, Cycle 1 Day 1 and Cycle 2 Day 1 of 28-day cycles QTc interval was a measure of time between the start of the Q wave and the end of the T wave and is dependent on the heart rate. A QTc interval adjusted using Bazette's correction (QTcB) was used in order to aid interpretation.
Progression Free Survival (PFS) Baseline to measured PD up to 9 months PFS was defined as the time from the date of the first dose of enzastaurin to the first date of documented progressive disease (PD) or the date of death from any cause, whichever occurred first. Participants who were not known to have died as of the data-inclusion cut-off date, and who did not have PD, PFS was censored at the date of the last progression-free disease assessment date prior to the date of any post discontinuation anticancer therapy. Participants who took any subsequent systemic anticancer therapy prior to PD or death, PFS was censored at the date of the last progression-free disease assessment prior to the date of any post discontinuation anticancer therapy.
Number of Participants With Adverse Events (AEs) or Who Died Baseline to study completion up to 24 months and 30-day post-study discontinuation Clinically significant events were defined as serious AEs (SAEs) and other non-serious AEs (regardless of causality). A summary of SAEs and other non-serious adverse events (AEs) regardless of causality is located in the Reported Adverse Events module. The number of participants who died included those who died due to an SAE (any cause) while on study and those who died due to progressive disease (PD) during the 30-day post-study discontinuation follow-up.
Duration of Stable Disease (SD) Time from SD to measured PD up to 9 months Duration of SD measured from date of first dose of enzastaurin to date of documented progressive disease (PD) or date of death from any cause, whichever occurred first, using Response Evaluation Criteria in Solid Tumors (RECIST v1.0). PD was defined as ≥20% increase in the sum of the longest diameter (LD) of target lesions, taking as reference the smallest sum LD since treatment began or appearance of ≥1 new lesions. SD was defined as no improvement and not meeting the requirements of PD using smallest sum LD since treatment began as reference. Participants with SD (or better) who had not died at data-inclusion cut-off date without PD, or participants who took subsequent systemic anticancer therapy prior to PD or death, duration was censored at date of last progression-free disease assessment prior to the date of post discontinuation anticancer therapy.
Pharmacokinetics-Minimum Observed Concentration (Cmin) of Total Analytes Cycle 1 Day 2-predose, Cycle 2 Day 1-predose and Cycle 3 Day 1-predose of 28-day cycles Cmin of enzastaurin + LSN326020 (a metabolite of LY317615) after loading dose in Cycle 1 and at a steady state during Cycles 2 and 3.
Overall Survival (OS) Baseline to date of death from any cause up to 24 months OS was defined as the time from the date of the first dose of enzastaurin to the date of death from any cause. Survival time was censored at the date of the last contact for participants who were still alive.
Time to Treatment Response Baseline to date of confirmed response up to 24 months Time to treatment response was defined as date of first dose of study drug to the date of confirmed complete response (CR) or partial response (PR) using Response evaluation Criteria in Solid Tumors (RECIST v1.0) criteria. CR was defined as the disappearance of all target and non-target lesions and normalization of tumor marker levels in non-target lesions. PR was defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. Time to treatment response was not evaluable, as there were no participants with CR or PR.
Change From Baseline in Carcinoembryonic Antigen (CEA) Response at Each Cycle Baseline and Cycles 1, 2, 3, 4, 5, 6 (28-day cycles) CEA levels were measured to detect potentially rapid-growing tumors in participants who received enzastaurin.
Duration of Complete Response (CR) or Partial Response (PR) (Duration of Response) Time from response to PD The duration CR or PR was defined as the time from first objective status assessment of CR or PR to the first date of documented progressive disease (PD) or death from any cause. CR and PR were determined using Response evaluation Criteria in Solid Tumors (RECIST v1.0) criteria. CR was defined as the disappearance of all target and non-target lesions and normalization of tumor marker levels in non-target lesions. PR was defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. PD defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions. Duration of response was not evaluable, as there were no participants with CR or PR.
