Alternative Schedule Sunitinib in Metastatic Renal Cell Carcinoma: Cardiopulmonary Exercise Testing

Study Summary

The purpose of this study is to determine the effect of a sunitinib administration schedule 2/1 (2 weeks of treatment followed by 1 week without) compared to a schedule 4/2 (4 weeks of treatment followed by 2 weeks without) on cardiopulmonary function in subjects with renal cell carcinoma. Subjects will be randomized 1:1 to one of two arms: 4/2 schedule of sunitinib administration or 2/1 schedule of sunitinib administration. Cardiopulmonary function will be assessed at baseline, week 4 (4/2 schedule only), week 5 (2/1 schedule only) and week 12. The investigators hypothesize that schedule 2/1 of sunitinib is not only better tolerated but will be associated with less fatigue and functional cardiovascular/muscular toxicity than the 4/2 schedule.

Primary Outcome

Exercise Capacity will be assessed using Cardiopulmonary Exercise Testing (CPET) to determine VO2peak. Higher VO2 peak measured in mg/ml/min indicates better cardiac function. Mean change in cardiac functions will be assessed by the difference in Relative Peak VO2 from baseline to 12 weeks in both the arms.
