Quality of life (QoL) among patients with renal cell carcinoma (RCC) treated with pazopanib versus sunitinib in the COMPARZ study.

346 Background: Pazopanib and sunitinib are targeted therapies associated with particular treatment-related side effects that may affect patients’ QoL. COMPARZ was a randomized, open-label, parallel group, phase III study of pazopanib vs. sunitinib in 1,110 subjects with advanced RCC who had not received prior systemic therapy. The study demonstrated pazopanib is non-inferior to sunitinib with respect to progression-free survival. The study also confirmed the differentiated safety profiles of the two drugs. Methods: QoL endpoints were assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), the Functional Assessment of Cancer Therapy-Kidney Symptom Index-19 (FKSI-19), the Cancer Therapy Satisfaction Questionnaire (CTSQ), and a Supplementary Quality of Life Questionnaire (SQLQ). Research to validate the SQLQ is currently ongoing. Each instrument was administered at baseline (except CTSQ) and then day 28 of every cycle. Changes in mean scores over time were analyzed and compare...
