Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

Eligible patients who fulfil criteria will be randomized into a controlled design (RCT) comparing the effects of 16 weeks intervention program with a maximum of 2 sessions per week ensuring a 24h rest period between similar sessions, for the same aims and muscular groups. All participants are assessed in primary and secondary outcome measures before and after the intervention period. The intervention is designed with: a) Resistance Exercise Training (REX); b) Control Group (CG).

We also expect to follow up those patients, after the intervention protocol terminus, using routine consultation on participating Hospitals, and acquiring data to support the long-term effects of the protocol. The follow-up will maintain the Onco-Hematology consultations routine and periodicity (6 months after last medical appointment), where all initial assessments will be undertaken.
Primary Study Purpose

TREATMENT

Blinding Strategy

TRIPLE

Participants Caregivers Outcome Assessors
Clinical evaluation is performed in invited hospitals, physical activity evaluation is performed by the outcomes assessor in Faculty of Sport of University of Porto. The investigator is the person who will conduct the intervention, and he's the one that will know what protocol is assigned to each patient, but without knowing the results from clinical and physical fitness evaluations.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Resistance Exercise Training

Patients in the REx program are submitted to resistance machine exercises for the major muscle groups aiming to achieve the intensity of 80% of 1-Repetition Maximum (1-RM). A warmup and cool down of 10 and 5 minutes, respectively, were included in each session aiming workloads of 60%-85% of peak heart rate (HRp). Enrolment through the REx program resistance machines will be conducted from major muscle groups to minor muscle groups, from polyarticular to monoarticular exercises, and alternating between agonist and antagonist contraction according to the following laydown: Leg Press -\> Leg Curl -\> Leg Extension -\> Chest Press -\> Latissimus Pulldown -\> Shoulder Press -\> Triceps Extension -\> Biceps Curl -\> Abdominal Crunch.
