PRIMARY outcome

Timeframe: Baseline to response (up to 30 weeks)

Population: All participants enrolled to initial farletuzumab only.

Defined using modified Gynecologic Cancer Intergroup (GCIG) criteria: Number of participants who achieved a 50% response = \>50% decrease from baseline CA-125 (higher of 2 pretreatment CA-125 assessments and the level must be at least 52.5 kU/L).

SECONDARY outcome

Timeframe: Baseline to response (up to 27 weeks)

Population: All participants enrolled to intial chemotherapy plus farletuzumab.

Time to Serologic Response is defined as the time (weeks) from the date of first farletuzumab infusion to first documentation of 50% decrease from baseline CA-125 (higher of 2 pretreatment CA-125 assessments and at least twice the upper limit of normal) and then confirmed after 21 days.

SECONDARY outcome

Timeframe: Baseline to response (up to 44 months)

Population: All participants enrolled to initial chemotherapy plus farletuzumab.

Calculated as the time from the first documentation of 50% or greater reduction in CA-125 to the first documentation of serologic progression or death due to any cause. Serologic progression was defined as the first date of the CA-125 level being \>2 X ULN on two occasions.

SECONDARY outcome

Timeframe: Baseline to response (up to 44 months)

The Overall Response Rate (ORR) will be determined by applying standard RECIST criteria to objective measures of disease, such as CT or MRI scans. Participants will be assigned to one of the categories of change in disease status, namely, "complete response" (CR), "partial response" (PR), "stable disease" (SD), or "progressive disease" (PD). ORR is defined as the percentage of participants with objective evidence of CR or PR.

SECONDARY outcome

Timeframe: Baseline to response (up to 44 months)

Population: All participants who received chemotherapy plus farletuzumab as well as those who continued on maintenance farletuzumab.

PFS is defined for participants treated in Chemo Plus Far as the time (in months) from date of first dose in Chemo Plus Far until date of the first observation of progression based on first date of the CA-125 \>2 X ULN on two occasions, or date of death, whatever the cause. If progression or death is not observed for a participant, the PFS time is censored at the later date of last tumor assessment or CA125 assessment without evidence of progression prior to the date of initiation of further anti-tumor treatment.

SECONDARY outcome

Timeframe: Baseline to response (up to 44 months)

Population: All participants who received chemotherapy plus farletuzumab as well as those who continued on maintenance farletuzumab.

Percentage of participants whose second remission was longer than their first remission. The length of remission will be determined for participants who attain CR or PR (or SD and investigator's assessment of clinical benefit). Prolongation of remission will be defined as a length of remission occurring on this study that is ≥ 1 day longer than the length of remission to the original therapy. The length of remission on this study (second remission) will be defined as the amount of time from the date of first CR or PR to the end of this remission.
