Exercise as Intervention in Chronic Lymphocytic Leukemia — ADRENALINE  

Chronic Lymphocytic Leukemia Clinical Trial

Official title: Randomised Controlled Clinical Trial of Exercise as Intervention in Chronic Lymphocytic Leukemia

Status Recruiting

Clinical Trial Summary

PURPOSE: The purpose of the study is to determine the effects of 16-weeks of exercise training, as measured by aerobic capacity, strength and physical function, and body composition, in patients with Chronic Lymphocytic Leukemia (CLL).

DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 16-week control group (no supervised exercise) or an intervention group of Resistance Training (REx). Before and after the 16-week protocol, patients will undergo several tests including: 1) a maximal cycle ergometer test, 2) Body Composition, 3) Muscle strength, 4) physical activity levels, 5) blood measures (e.g. immune and inflammatory functions).

DATA ANALYSES & SAFETY ISSUES: For outcomes, group change differences from baseline to 16-weeks will be compared with ANCOVA. Resistance training is a very safe exercise modality already studied in other cancer patients. The regular use of vigorous-intensity exercise has been used extensively in exercise training. It will always be respected for each subject's safety tolerance while challenging.

HYPOTHESIS: The investigators hypothesize that the protocol will be feasible exercise interventions for people with CLL and will improve health and fitness markers.

Clinical Trial Description

PURPOSE: The purpose of the study is to determine the effects of 16-weeks of exercise training, as measured by aerobic capacity, strength and physical function, and body composition, in patients with CLL and without any prior treatment.

DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 16-week control group (no supervised exercise) or an intervention group of Resistance Training (REx). Before and after the 16-week protocol, patients will undergo several tests including: 1) a Cardiopulmonary Exercise Test with Electrocardiogram (CPET+ECG) maximal cycle ergometer test, 2) a dual-energy X-ray absorptiometry (DEXA) Body Composition test, 3) a Muscle strength test with dynamometry, 4) a characterization of physical activity (PA) levels with accelerometry, and 5) blood measures (e.g. immune and inflammatory functions). The REx group will undertake a strength-based type of training with intensities near 80% of 1-Repetition Maximum (1-RM), with individual supervision (personal training approach).

DATA ANALYSES & SAFETY ISSUES: For outcomes, group change differences from baseline to 16-weeks will be compared with ANCOVA. Resistance training is a very safe exercise modality already studied in other cancer patients. The regular use of vigorous-intensity exercise has been used extensively in exercise training. It will always be respected for each subject's safety tolerance while challenging.

HYPOTHESIS: The investigators hypothesize that the protocol will be feasible exercise interventions for people with CLL and will improve health and fitness markers. It is also expected to have a positive correlation between physical fitness improvement and blood and immunologic parameters. ;
