About
This was a randomized, open-label, parallel group Phase III non inferiority study to evaluate the efficacy and safety of pazopanib compared with sunitinib in subjects with advanced renal cell carcinoma (RCC) who had not received prior systemic therapy for advanced or metastatic RCC.
Full description
Approximately 876 eligible subjects (approximately 438 per treatment arm) were planned to be enrolled over the course of the study. However, due to higher than expected withdrawal rates and discordance rates between independent review committee (IRC) and investigator assessments of progression, the protocol was amended (Protocol Amendment 4) to increase the number of subjects to approximately 1100 total by including all subjects enrolled in CPZP034A2301 (hereafter referred as Study A2301) and CPZP034A2201 (a sub study of CPZP034A2301, hereafter referred as Study A2201 with NCT01147822).
The subjects were centrally randomized in 1:1 ratio to receive either 800mg pazopanib to be administered once daily orally continuous dosing or 50mg sunitinib to be administered in 6-week cycles: 50mg orally daily for 4 weeks followed by 2 weeks off treatment. Subjects were permitted to receive supportive care throughout the study including transfusion of blood and blood products, treatment with antibiotics, anti-emetics, anti-diarrheal agents, analgesics, erythropoietin, or bisphosphonates, when appropriate. The study treatment continued until subjects experience disease progression, unacceptable toxicity, withdraw consent, or death.
