PURPOSE: Angiogenesis is important for epithelial ovarian cancer (EOC) growth, and blocking angiogenesis can lead to EOC regression. Cediranib is an oral tyrosine kinase inhibitor (TKI) of vascular endothelial growth factor receptor (VEGFR) -1, VEGFR-2, VEGFR-3, and c-kit.
PATIENTS AND METHODS: We conducted a phase II study of cediranib for recurrent EOC or peritoneal or fallopian tube cancer; cediranib was administered as a daily oral dose, and the original dose was 45 mg daily. Because of toxicities observed in the first 11 patients, the dose was lowered to 30 mg. Eligibility included <or= two lines of chemotherapy for recurrence. End points included response rate (via Response Evaluation Criteria in Solid Tumors [RECIST] or modified Gynecological Cancer Intergroup CA-125), toxicity, progression-free survival (PFS), and overall survival (OS).
RESULTS: Forty-seven patients were enrolled; 46 were treated. Clinical benefit rate (defined as complete response [CR] or partial response [PR], stable disease [SD] > 16 weeks, or CA-125 nonprogression > 16 weeks), which was the primary end point, was 30%; eight patients (17%; 95% CI, 7.6% to 30.8%) had a PR, six patients (13%; 95% CI, 4.8% to 25.7%) had SD, and there were no CRs. Eleven patients (23%) were removed from study because of toxicities before two cycles. Grade 3 toxicities (> 20% of patients) included hypertension (46%), fatigue (24%), and diarrhea (13%). Grade 2 hypothyroidism occurred in 43% of patients. Grade 4 toxicities included CNS hemorrhage (n = 1), hypertriglyceridemia/hypercholesterolemia/elevated lipase (n = 1), and dehydration/elevated creatinine (n = 1). No bowel perforations or fistulas occurred. Median PFS was 5.2 months, and median OS has not been reached; median follow-up time is 10.7 months.
CONCLUSION: Cediranib has activity in recurrent EOC, tubal cancer, and peritoneal cancer with predictable toxicities observed with other TKIs.
