Brief Summary
This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.

Conditions
Outcome Measures
Primary Outcomes (2)
Percentage of completed exercise sessions (Feasibility)
Feasibility will be defined through intervention adherence. Will set a priori thresholds for this outcome to define success as detailed. For evaluating the uptake of the intervention, will assess the percentage of enrolled participants who complete at least 70% of prescribed exercise sessions. Will calculate the proportion of participants meeting this threshold and compare it to the predefined success criterion of 80%. Descriptive statistics (percentages) will be reported along with 95% confidence intervals.
Up to 6 months
Intervention attrition rate (Feasibility)
Feasibility will be defined through intervention attrition. Will set a priori thresholds for this outcome to define success as detailed. To examine attrition from the trial, will calculate the attrition rate by dividing the number of participants who drop out of the trial by the total number of enrolled participants. The a priori acceptable attrition rate is no greater than 20%. Descriptive statistics (attrition rate) will be presented, and a comparison with the predefined threshold will be made.
Up to 6 months
Secondary Outcomes (2)
Weekly recruitment rate
From the date that the study is activated at all 4 enrolling sites and the first patient is enrolled, assessed up to 58 weeks
Retaining a diverse patient population
From the date that the study is activated at all 4 enrolling sites and the first patient is enrolled, assessed up to 58 weeks
Other Outcomes (7)
Change in 6 Minute Walk Test (6MWT) distance
From baseline to end of intervention, which is defined as end of chemotherapy (within 4 weeks of the final chemotherapy administration) or up to a total of 6 months of intervention, whichever comes first
Change in grip strength
From baseline to end of intervention, which is defined as end of chemotherapy (within 4 weeks of the final chemotherapy administration) or up to a total of 6 months of intervention, whichever comes first
Objective changes in physical activity
From baseline to end of intervention, which is defined as end of chemotherapy (within 4 weeks of the final chemotherapy administration) or up to a total of 6 months of intervention, whichever comes first
- +4 more other outcomes
Study Arms (1)
Supportive care (DEFEND)
EXPERIMENTALPatients complete supervised TH exercise sessions consisting of progressive resistance exercise BIW and complete unsupervised aerobic exercise sessions over 30 minutes TIW until the end of SOC chemotherapy or up to a total of 6 months, whichever comes first, in the absence of disease progression or unacceptable toxicity. Patients also receive adjustable-weight dumbbells on study and wear an accelerometer throughout the study.
Interventions
Complete supervised TH progressive resistance exercise sessions
Complete supervised TH progressive resistance exercise sessions
Complete unsupervised aerobic exercise sessions
Eligibility Criteria
You may qualify if:
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Participants must have histologically confirmed cancer
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Participants must be initiating outpatient cytotoxic chemotherapy for curative intent (for any malignancy) of at least 10 weeks duration (with or without concurrent radiation, immunotherapy, or other targeted therapy). Patients must be enrolled and baseline measures collected on or before administration of their second cycle of cytotoxic therapy. Patients receiving outpatient cytotoxic chemotherapy for curative intent in the neoadjuvant or adjuvant setting for solid tumors are eligible. Patients receiving outpatient cytotoxic chemotherapy given for curative intent for hematologic malignancies, as well as patients receiving definitive chemoradiation for solid tumors, are also eligible. Regimens of immunotherapy or monoclonal antibodies ONLY are not eligible
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Age 18-64 years
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Patients cannot have metastatic cancer
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Patients cannot have documentation in the medical record of severe cardiovascular, respiratory or musculoskeletal disease or joint problems that preclude moderate physical activity. Examples would include unstable angina, recent myocardial infarction, oxygen-dependent pulmonary disease, and osteoarthritis requiring imminent joint replacement. Moderate arthritis that does not preclude physical activity is not a reason for ineligibility
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Patients cannot be pregnant, because this study involves remotely delivered exercise, and cannot be breast-feeding as patients must be receiving cytotoxic chemotherapy, during which breast-feeding is contraindicated
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Patients cannot have documentation in the medical record of current alcohol or substance abuse
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Engaged in full time gainful employment of at least 30 hours per week at the time of cancer diagnosis
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Currently no self-report of engagement in competitive sports (e.g. not training for running races, triathlons, etc) AND no self-report of twice weekly progressive resistance exercise training within the past year
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Self-reported ability to walk for 6 minutes (use of assistive devices will be allowed)
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Not participating in another weight loss, physical activity, or dietary intervention clinical trial
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Predicted 6MWT distance of 450 meters or less
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Concurrent enrollment in treatment or supportive care trials (other than those focused on weight loss or exercise) is allowed with the permission of the Alliance Executive Officer and both studies' study chairs
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): Eligibility is restricted to individuals who can comprehend and read English given that participation in the study will require the ability to read intervention materials and work with a coach through telehealth sessions
- REGISTRATION ELIGIBILITY CRITERIA (STEP 1): The trial is unable to accommodate the needs of deaf or blind participants as the study relies on language and visualization of exercise through telehealth sessions
