the PaLiDo study, a phase II nonrandomized multicenter study
OBJECTIVE: The increasing number of negative trials for ovarian cancer treatment has prompted an evaluation of new biologic agents, which in combination with chemotherapy may improve survival. The aim of this study was to investigate the response rate in platinum-resistant, KRAS wild-type ovarian cancer patients treated with pegylated liposomal doxorubicin (PLD) supplemented with panitumumab. PATIENTS AND METHODS: Major eligibility criteria were relapsed ovarian/fallopian/peritoneal cancer patients with platinum-resistant disease, measurable disease by GCIG CA125 criteria and KRAS wild-type. Patients were treated with panitumumab 6 mg/kg day 1 and day 15 and with PLD 40 mg/m day 1, every 4 weeks. RESULTS: Forty-six patients were enrolled by 6 study sites in this multi-institutional phase II trial. The response rate in the intention-to-treat population (n = 43) was 18.6%. Progression-free and overall survival in the intention-to-treat population was 2.7 months (2.5-3.2 months, 95% confidence interval) and 8.1 months (5.6-11.7 months, 95% confidence interval), respectively. The most common treatment-related grade 3 toxicities included skin toxicity (42%), fatigue (19%), and vomiting (12%). CONCLUSIONS: The combination of PLD and panitumumab demonstrates efficacy in platinum refractory/resistant patients but the skin toxicity was considerable.
