Efficacy

CarboPt+PLD vs CarboPt+Pac:

PFS: 11.3 vs 9.4 months, HR: 0.82 (0.72-0.94, p=0.005)
OS: 30.7 vs 33.0 months, HR: 0.99 (0.85-1.16, p=0.94)
Clinically Significant Adverse Events

CarboPt+PLD vs CarboPt+Pac:
Serious AE: two treatment related fatalities in CarboPt+PLD arm: 1 cerebral hemorrhage and 1 acute myeloid leukemia
Grade 3-4 AE: any severe non-hematologic toxicity (28.4 vs 36.8%), alopecia (grade 2 or greater) (7 vs 83.6%), sensory neuropathy (4.9 vs 26.9%), hypersensitivity reactions (5.6 vs 18.8%), PPE (mostly grade 2) (12.0 vs 2.2%), nausea (35.2 vs 24.2%)
Conclusion

Carboplatin+PLD has similar PFS and OS to carboplatin+paclitaxel with less sensory neuropathy
