An interventional study of Interval Exercise Training (IET) in Stem Cell Transplantation, Hematopoietic, sponsored by UNC Lineberger Comprehensive Cancer Center. Completed at 1 site in United States. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2015-10-16.

The primary objective of this study is to demonstrate the efficacy of a pre-transplant, interval exercise training (IET) intervention, in increasing peak oxygen uptake (VO2peak) scores on cycle ergometry. This study will have a lead-in phase to ensure that IET is feasible in this population. Secondary objectives include documenting the safety of IET in this population, evaluating the correlation of VO2peak with other methods of measuring pre-transplant cardiorespiratory performance, comparing the 6 minute walk distance (6MWD) pre and post IET, and establishing the feasibility of the 6MWD when performed unsupervised by a health care professional.
Eligible patients include 40 evaluable autologous (n=20) and allogeneic (n=20; 10 full intensity and 10 reduced intensity) transplant patients deemed appropriate for exercise intervention by their treating physician. The investigators will enroll no more than 50 patients onto this trial. Results of this study will inform a randomized, multi-site study of a pre-transplant exercise intervention.
The primary purpose of the study is to determine the ability of a pre-transplant exercise intervention to improve cardiorespiratory performance (measured by VO2peak). If the safety of this approach is documented, and its efficacy demonstrated, a foundation will be laid for a larger, randomized, multi-center study to formally determine the benefit of the pre-transplant exercise intervention.
We plan to analyze the effect of IET on VO2peak in the auto and allo groups separately given their different course of treatment and outcomes. Study subjects will be recruited after they and their transplant teams have decided that they will undergo HCT. Following recruitment, patients will undergo baseline fitness assessments and then receive an individualized IET prescription for a duration of 6 weeks prior to stem cell mobilization (auto) or prior to hospitalization for conditioning (allo). For the first two weeks, subjects will undergo three times weekly 3 minute interval training during walking at 60-70% MHR. This will be followed by three times weekly aerobic interval training for 5 three-minute bouts at 65-85% maximum heart rate per session for 4 weeks.
All patients will also be provided with a FitBit accelerometer. Prior to transplant, patients will undergo follow-up fitness assessments. All patients will undergo activity tracking by accelerometry (FitBit) and admission/weekly symptom/HRQOL tracking by electronic survey throughout the post-transplant hospitalization. Also during hospitalization, all patients will perform weekly clinician supervised 6MWD testing while inpatient. One of the weekly tests during hospitalization will include patient self-administered (clinician observed) 6MWD, along with the clinician supervised 6MWD. Unsupervised patient performed 6MWD will be considered feasible if all patients who perform 6MWD can do so safely, and if for 80% of patients, the patient-performed 6MWD values are within 10% of the corresponding clinician supervised 6MWD results. If feasibility is met, we will ask patients to perform the 6MWD weekly for 4 weeks post discharge and record their distance.
