HIIT

The primary aim of this study is to evaluate the feasibility of a supervised high intensity interval training (HIIT) program during first-line dual immune checkpoint inhibitor (ICI) therapy (nivolumab plus ipilimumab) in patients with advanced renal cell carcinoma (RCC). The second aim is to generate preliminary data on the effects of exercise on the immune cell phenotype and function, gut microbiota composition, physical fitness, patient-reported outcomes and clinical outcomes. This is a two-arm randomized controlled pilot trial in which 30 patients with advanced RCC scheduled to receive first-line nivolumab plus ipilimumab will be randomized in 1:1 ratio to an exercise intervention group or usual care group. The exercise intervention consists of two 60-minute supervised HIIT sessions per week, delivered by oncology-trained physiotherapists and one additional home-based moderate-intensity aerobic exercise sessions per week. The intervention starts with the first cycle of immunotherapy and continues for four treatment cycles. Participants in both groups will receive usual care and general exercise guidelines. Measurements include blood and stool sampling for microbiome and immune parameters analysis, physical fitness assessments, physical fitness monitoring, body composition measurements, and patient-reported outcomes related to quality of life, fatigue, depression, sleep and diet.
