The primary end point was progression-free survival (PFS). Other end points were objective response rate and safety. The study was originally planned for 244 patients. The trial was temporarily placed on hold after 125 patients were randomized while the results of another trial were being reviewed and the sponsor decided not to resume enrollment. The interim analysis became the final analysis.Results: The median PFS was 5.6 months for canfosfamide + PLD (n = 65) versus 3.7 months for PLD (n = 60) (hazards ratio, 0.92; P = 0.7243). A preplanned subgroup analysis showed that 75 patients with platinum-refractory or primary platinum-resistant OC had a median PFS of 5.6 months for canfosfamide + PLD versus 2.9 months for PLD (hazards ratio, 0.55; P = 0.0425). Hematologic adverse events were 66% on the canfosfamide + PLD arm versus 44% on the PLD arm, manageable with dose reductions. Nonhematologic adverse events were similar for both arms. The incidence of palmar-plantar erythrodysesthesia and stomatitis was lower on canfosfamide + PLD (23%, 31%, respectively) versus (39%, 49%, respectively) on PLD.Conclusions: Overall median PFS showed a positive trend but was not statistically significant. The median PFS in the platinum-refractory and primary platinum-resistant OC patients was significantly longer for canfosfamide + PLD versus PLD. Canfosfamide may ameliorate the palmar-plantar erythrodysesthesia and stomatitis known to be associated with PLD. Further study of this active well-tolerated regimen in platinum-refractory and primary platinum-resistant OC is planned.This study was registered at www.clinicaltrials.gov: NCT00350948. ER -
