A Study to Evaluate Pazopanib as an Adjuvant Treatment for Localized Renal Cell Carcinoma (RCC)

Novartis Pharmaceuticals1,538 enrolled

Overview

This randomized Phase III study is to evaluate whether pazopanib compared with placebo can prevent or delay recurrence of kidney cancer in patients with moderately high or high risk of developing recurrence after undergoing kidney cancer surgery.

The primary objective of this ongoing study was to evaluate DFS with pazopanib 600 mg daily initial dose as compared with placebo as adjuvant therapy for subjects with localized/locally advanced RCC following nephrectomy. Subjects with locally recurrent renal cell carcinoma (RCC), bilateral RCC, or history of another malignancy were excluded from enrolling in the study. The study was comprised of three successive study periods: 1) the Screening/Baseline period, 2) the study treatment period, and 3) the DFS /OS follow-up period. The Screening/Baseline period had a maximum duration of 12 weeks from the date of nephrectomy to the date of randomization. After a subject met all the eligibility criteria and completed all the required baseline assessments, the subject was randomized in a 1:1 ratio to receive once daily blinded treatment with either pazopanib 600 mg as initial dose or matching placebo based on pre-defined stratification factors. Subjects received continuous daily treatment until completion of the 12-month treatment period, disease recurrence, or unacceptable toxicity/intolerance. Subsequent adjuvant therapies for RCC were not allowed. During the study treatment and DFS follow-up periods, subjects received routine safety and efficacy assessments. The study treatment period was 12 months. Subjects received continuous daily treatment until completion of the 12 month treatment period, disease recurrence, or unacceptable toxicity/intolerance. Subsequent adjuvant therapies for RCC were not allowed. All subjects, regardless of study treatment status (i.e. premature discontinuation or completion of the 12-month treatment), were to be followed with routine imaging assessments and remain blinded until objective evidence of disease recurrence was obtained or until the study achieved the required number of events for the primary endpoint of DFS (319 events). After objective evidence of disease recurrence was obtained, subjects could be unblinded and received the first-line treatment for metastatic RCC per local standard of care. All subjects were off treatment for at least 4 years at the end of study.

Health-related Quality of Life (HRQoL) With Pazopanib 600 mg Daily Initial Dose vs. Placebo Assessed Using NCCN/Functional Assessment of Cancer Therapy-Kidney Symptom Index -19 (FACT FKSI-19) Total Score

Health outcome and quality of life as measured by NCCN/FACT FKSI-19 questionnaire. The FKSI-19 is a disease-specific instrument that measures disease and treatment-related symptoms specifically in renal cancer patients in 4 domains (FKSI-DRS-P, FKSI-DRS-E, FKSI-TSE, FKSI-FWB) experienced in the past 7 days. Participants are asked to respond to a total of 19 questions regarding symptoms, side effects, and well being by using a 5-point scale (0=not at all, 1=a little bit, 2=somewhat, 3=quite a bit, 4=very much; possible total score of 0 to 76). A negative mean indicates a worsening of condition. DFS: disease-free survival; FU: follow up
