Combination trabectedin and pegylated liposomal doxorubicin improved PFS for patients with relapsed ovarian cancer in a study presented at the 33rd Congress of the European Society for Medical Oncology in Stockholm.
Bradley J. Monk, MD, professor in the department of obstetrics and gynecology at the University of California Irvine Medical Center, presented results of the multicenter phase-3 study that compared the safety and efficacy of trabectedin (Yondelis; Zeltia, Johnson and Johnson) plus pegylated liposomal doxorubicin with pegylated liposomal doxorubicin alone.
The study included 672 patients with a median age of 57 years. The patients were randomly assigned to pegylated liposomal doxorubicin 30 mg/m2 over 60 to 90 minutes with trabectedin 1.1 mg/m2 over three hours every three weeks or pegylated liposomal doxorubicin 50 mg/m2 every four weeks.
Median length of PFS was 7.3 months among women assigned to combination, compared to 5.8 months for those assigned to pegylated liposomal doxorubicin alone. Patients assigned to combination therapy who relapsed more than six-months following first-line therapy had a median PFS of 9.2 months, compared with those assigned to pegylated liposomal doxorubicin alone whose median PFS was 7.5 months.
