Enrollment: 1100
Healthy volunteers: no

Brief summary:
This research is being done to find out if Carboplatin and Taxane works better alone or when given with an experimental drug called MORAb-003(farletuzumab) in subjects with first platinum sensitive relapsed ovarian cancer.

Detailed description:

Arms:
arm 1: Participants will receive farletuzumab 1.25 milligram per kilogram (mg/kg) administer as an intravenous (IV) infusion weekly, followed by taxane (paclitaxel \[175 milligram per meter square {mg/m\^2}\] or docetaxel \[75 mg/m\^2\]), administer as IV infusion and followed by carboplatin (to maintain area under curve \[AUC\] 5-6 milligram per milliliter per minute \[mg/mL/minute\]), administer as IV infusion, every three weeks, on Day 1 of each 21-day cycle for 6 cycles (combination therapy). Following completion of combination therapy, maintenance treatment with farletuzumab 1.25 mg/kg, administer as IV infusion, weekly is given until disease progression. arm 2: Participants will receive farletuzumab 2.5 mg/kg administer as an IV infusion weekly, followed by taxane (paclitaxel \[175 mg/m\^2\] or docetaxel \[75 mg/m\^2\]), administer as IV infusion and followed by carboplatin (to maintain AUC 5-6 mg/mL/minute), administer as IV infusion, every three weeks on Day 1 of each 21-day cycle for 6 cycles (combination therapy). Following completion of combination therapy, maintenance treatment with farletuzumab 2.5 mg/kg, administer as IV infusion, weekly is given until disease progression. arm 3: Participants will receive farletuzumab-matched placebo (0.9 percent \[%\] saline) administer as an IV infusion weekly, followed by taxane (paclitaxel \[175 mg/m\^2\] or docetaxel \[75 mg/m\^2\]), administer as IV infusion and followed by carboplatin (to maintain AUC 5-6 mg/mL/minute), administer as IV infusion, every three weeks on Day 1 of each 21-day cycle for 6 cycles (combination therapy). Following completion of combination therapy, maintenance treatment with farletuzumab-matched placebo (0.9% saline), administer as IV infusion, weekly is given until disease progression.

Interventions: intervention 1: Farletuzumab intervention 2: Carboplatin intervention 3: Taxane intervention 4: Farletuzumab-matched placebo
Intervention descriptions: intervention 1: Farletuzumab IV infusion. intervention 2: Carboplatin IV infusion. intervention 3: Taxane (Paclitaxel or Docetaxel) IV infusion. intervention 4: Farletuzumab-matched placebo IV infusion.
