Background: In an open-label, multicenter, randomized phase III study comparing the combination of trabectedin and PLD to PLD alone in patients with relapsed ovarian cancer, the combination demonstrated significantly improved progression free survival and response rates, manageable non-cumulative toxicity, and fewer PLD-associated adverse events. We studied the impact of the combination of trabectedin with PLD on the quality of life (QoL)/patient-reported outcomes (PRO) evaluated as part of the trial. Methods: QoL/PRO questionnaires, EORTC-QLQ C30, OV28, and EQ-5D were completed by patients at screening and on Day 1 of every other treatment cycle starting with Cycle 1, and at the end-of-treatment visit. Global health status/QoL, fatigue, rain subscales from QLQ C30, and abdominal pain/GI symptoms scale from OV28 were chosen a priori for primary analyses. Other scales of the three questionnaires were analyzed on a supportive basis. Results: A total of 672 patients were randomized. 663 (98%) completed at least the baseline questionnaires. Median cycles of treatment was 6 (131 days) for the combination arm and 5 (143 days) for the monotherapy arm. Mixed effects models (using a covariance structure of AR[1]) predicting the score at baseline and follow-up scores as a function of treatment, days after baseline, and interaction between treatment and days after baseline showed no significant differences between the treatment arms for any of the prespecified scales. Similar analyses of other scales, including EQ-5D Health Index scores and Health State on the Visual Analog Scale, support the findings. Conclusions: The addition of trabectedin to PLD results in superior efficacy in patients with relapsed ovarian cancer, with no added decrement to overall health status as assessed by PRO.
