Virtual Exercise for Multiple Myeloma

Overview

The primary objective of this pilot study is to determine the safety and feasibility a 12-week virtually supported home-based aerobic and resistance exercise program progressing cancer survivors with Multiple Myeloma to meet standards identified in the 2019 Exercise Guidelines for Cancer Survivors. The protocol will be measuring recruitment, adherence, completion, cost tracking, as well as fitness and quality of life outcomes. The study will be a single-group prospective before and after study that will help inform a future larger-scale project. We will aim to recruit 25 participants. The Health Research Ethics Board of Alberta Cancer Committee will approve this study. Participants will participate in a combined resistance and aerobic exercise program biweekly for 12 weeks. Exercise sessions will be supported and progressive in nature, between 40 and 75 minutes each. Analyses: fitness testing and quality of life scales will be administered before and after the intervention. Scores will be compared to evaluate changes over the course of the intervention. Safety and feasibility information will be collected throughout the study and evaluated to determine program feasibility. Program satisfaction will be evaluated using a satisfaction survey.

Multiple myeloma (MM), a cancer of the plasma cells in bone marrow, is associated with osteolytic bone destruction, leading to deformities, chronic pain, reduced mobility and functioning, fatigue, and risk of fracture. Although incurable, newly developed therapies are extending survival, but some with significant side-effects. Patients may be living longer but with lasting, debilitating side-effects. Exercise has been proposed as a way to optimize patient function and quality of life in the face of lasting symptom burden. However, current evidence-informed exercise guidelines for cancer survivors may not be appropriate for those with bone fragility, including those with MM, as they are based on findings from studies in breast and prostate cancers. In MM specifically, the literature presents mixed results, and several studies have limited generalizability, reproducibility, or were underdosed. The main objective of this study is to determine the safety and feasibility of a 12-week virtually supported home-based aerobic and resistance exercise program that aims to progress individuals to the 2019 Exercise Guidelines for Cancer Survivors in a sample of cancer survivors with multiple myeloma, as defined by: * Recruitment rate: ≥ 21 participants consenting to the study over a 7-month recruitment period (primary endpoint) * Completion rate: ≥ 80% of participants consenting to the study complete the 12-week assessment * Safety: no increase in the rate of bony events above those estimated to occur in the target population * Adherence: average completion of ≥ 75% of the exercise prescription amongst participants We will aim to recruit 25 participants from clinics at the local cancer hospital, the local disease-group support society, and from the currently accruing Alberta Cancer Exercise program. Subjects will be screened for eligibility and if they meet all eligibility criteria, an information letter of the study will be provided, and they will be asked to contact the investigators if interested in taking part in the study. All participants will be required to provide written informed consent as per the Health Research Ethics Board of Alberta: Cancer Committee (HREBA). Participants will participate in a 12-week virtually supported home-based aerobic and resistance exercise program, twice weekly using the Heal-Me application. Sessions will be completed as virtual live classes or supported follow-along independent home workouts. Sessions will progress in duration and difficulty over the course of the program, aiming to have participants meet the 2019 Exercise Guidelines for Cancer Survivors by the end of the program. Each session will include aerobic exercise (i.e. walking, cycling, or cardio circuit), and a full-body resistance training routine using free weights, body weight exercises, and/or bands, followed by balance and stretching exercises. Analyses: Demographic and medical information will be presented using median and range and percentage for interval and nominal data, respectively. Descriptive statistics (mean ± SD and frequencies) will be used to report safety and feasibility measures. Adherence will be tracked as the percentage of total training load prescribed that was actually completed. Wilcoxon Signed Rank Tests will be used to compare and pre- and post-intervention fitness assessment and quality of life scores. All analyses will be conducted using Stata/MP (version 13.0, StataCorp LLC, College Station, TX), with alpha set to 0.05.
