E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is progression-free survival (PFS). PFS is defined as the time from the date of randomization to the earliest of the dates of first objective disease progression per RECIST 1.1 with modifications or death from any cause. Subjects not meeting these criteria by the analysis data cutoff date will have their PFS time censored at their last evaluable radiologic disease assessment date. For the purposes of the primary analysis, the determination of radiologic disease progression per RECIST 1.1 with modifications will be based on investigator assessments. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The primary analysis is planned when a minimum of 510 PFS events (per investigator review) have been observed |
|
E.5.2 | Secondary end point(s) |
• Overall Survival
• Objective Response Rate (ORR)
• Duration of response (DOR)
• CA-125 response rate per GCIG and change in CA-125
• Incidence of adverse events and significant laboratory abnormalities
• Pharmacokinetics of AMG 386 (Cmax and Cmin)
• Incidence of the occurrence of anti-AMG 386 antibody formation
• Patient reported HRQOL and ovarian cancer related symptoms using FACT-O
• Overall health status using EQ-5D |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The OS primary analysis will occur after 600 OS events have been observed. It is anticipated that it will occur approximately 44 months after the first subject is randomized. |
