Exercise to Reduce Chemotherapy-Induced Peripheral Neuropathy
This randomized, controlled, pilot experiment will evaluate the effects of an aerobic walking intervention on OIPN (oxaliplatin-induced peripheral neuropathy) in patients with gastrointestinal (GI) cancer who are already prescribed oxaliplatin (85 mg/m2 every other week for at least six cycles) by their oncologists. Oxaliplatin is a standard chemotherapy treatment for invasive GI cancers that causes OIPN in 85-95% of patients.
Background: Over 190,000 men and women will be diagnosed in 2018 with invasive gastrointestinal (GI) cancers (e.g, colorectal and gastric cancer) for which oxaliplatin is a standard chemotherapy treatment. However, 85-95% of these patients develop oxaliplatin-induced peripheral neuropathy (OIPN). Currently, OIPN is the primary dose-limiting factor of oxaliplatin-based regimens, because persistent OIPN can impair physical function and quality of life (QOL) years after treatment completion. There are no effective treatments for OIPN. Four randomized controlled trials and two quasi-experiments have reported positive effects of at least 10 minutes/day of moderate-intensity aerobic exercise, 2-5 days/week over at least 6-8 weeks on chemotherapy-induced peripheral neuropathy. Exercise-enhanced circulation could re-distribute neurotoxic drugs away from vulnerable neurons, reduce oxidative stress, and help to prevent OIPN. However, all the prior trials had critical study limitations and all but two studies evaluated OIPN as a secondary outcome. Thus, this prospective, randomized, controlled, pilot experiment will evaluate the efficacy of an aerobic walking intervention for OIPN in GI cancer patients who are already prescribed oxaliplatin (85 mg/m2 every other week for at least six cycles) by their oncologists. The "MI-Walk intervention"- an 8-week motivational enhancement therapy (MET)- and home-based aerobic walking intervention-will be tested in this study. Specific aims: The specific aims and hypotheses are to: Aim 1: Evaluate the effect of the MI-Walk Intervention on OIPN severity at 8 weeks (T6) compared to physical activity (PA) education alone. Hypothesis: Participants who receive the MI-Walk intervention will exhibit less severe OIPN at T6 than participants who receive PA education alone. Aim 2: Explore the effect of the MI-Walk intervention on total oxaliplatin received, and QOL at T6 compared to PA education alone. Hypothesis: Participants who receive the MI-Walk intervention will receive higher total doses of oxaliplatin and report higher QOL at T6 than participants who receive PA education alone. Aim 3: Evaluate the feasibility of the MI-Walk intervention. Research Questions: Among patients receiving oxaliplatin, 1) how acceptable is the intervention? 2) what percent of patients will enroll in, complete, and adhere to the walking intervention? 3) what participant characteristics are associated with study compliance, adherence, completion, and acceptability? 4) What, if any, adverse events will result from the MI-Walk intervention? Study design: Sixty GI cancer patients will be recruited at multiple cancer clinics within the week before their second oxaliplatin cycle. All participants will receive a PA education pamphlet. Half (n=30) will receive the MI-Walk Intervention. These patients will receive a tailored progressive walking plan, supplemental cancer treatment & exercise education, patient testimony, HR-enabled pedometer and PA-tracking app, exercise diary, and semi-scripted brief MET (motivational interviewing, SMAART goals, and if-then statements) from research staff before practicing the intervention at home for 8 weeks. Additional brief MET sessions at 2 (T3) and 4 weeks (T4), progress summaries at T3, T4, and T6, a private email group, weekly group walking events, and peer accountability phone calls/email will be used to engage and support participants. To level attention, both groups will receive regular phone assessments of intervention-related adverse events at 1 week (T2), T3, T4, and 6 weeks (T5). Outcomes will be measured at (T1) and 8 weeks after (T6) intervention initiation. The outcome measures include the 0-10 NRS of OIPN symptom severity (primary outcome measure); and EORTC QLQ-CIPN20 self-report survey, cumulative oxaliplatin dose, and EORTC QLQ-C30. The study will also record feasibility, adherence, acceptability, and intervention fidelity data. Multiple linear regression will be used to evaluate the inter-group differences in the T1 to T6 change in mean NRS scores (OIPNΔ), controlling for T6 total oxaliplatin received (OXALIT6), and the interaction between the intervention and OXALIT6. Mediation analysis will be used to explore the secondary outcomes. Future Directions: This study will be among the first to provide efficacy and feasibility data for an 8-week home-based aerobic walking intervention to reduce OIPN - a common chemotherapy side effect, for which there are no good treatments. This pilot study will inform the design of larger phase III trials to evaluate the efficacy of aerobic walking for OIPN, and potential mediators (e.g., vascular biomarkers) in this relationship.

| Primary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Sensory neuropathy at 8 weeks | The 9-item European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Chemotherapy-Induced Peripheral Neuropathy Scale (CIPN20) sensory subscale will be used to measure sensory neuropathy. Each item is rated on a scale from 1 ("not at all") to 4 ("very much"), and the total raw score ranges from 9 to 36. The raw scores will be linearly transformed to a 0 to 100 scale (higher scores represent worse CIPN severity). | At 8 weeks |
| Secondary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Motor Neuropathy at 8 weeks | The 8-item EORTC QLQ-CIPN20 motor subscale will be used to measure motor neuropathy. Each item is rated on a scale from 1 ("not at all") to 4 ("very much"), and the total raw score ranges from 8 to 32. The raw scores will be linearly transformed to a 0 to 100 scale (higher scores represent worse CIPN severity). | At 8 weeks |
| Autonomic Neuropathy at 8 weeks | The 3-item EORTC QLQ-CIPN20 autonomic subscale will be used to measure autonomic neuropathy. Each item is rated on a scale from 1 ("not at all") to 4 ("very much"), and the total raw score ranges from 3 to 12. The raw scores will be linearly transformed to a 0 to 100 scale (higher scores represent worse CIPN severity). | At 8 weeks |
| Oxaliplatin dose at 8 weeks | Cumulative oxaliplatin dose (mg/m2 of oxaliplatin received) data will be gathered from the electronic medical record (EMR). | At 8 weeks |
| Quality of life at 8 weeks | The EORTC QLQ 30-Item Questionnaire (EORTC QLQ-C30) is a patient-reported measure of cancer-specific QOL. Participants rate the degree that each item has applied to them during the past week on a four-point Likert scale (1, not at all; 4, very much). The average of the item scores gives a raw score and the raw score will be transformed to a 0 to 100 scale. Higher scores indicate higher QOL. | At 8 weeks |
| Mood at 8 weeks | The 4-item emotional functioning (EF) subscale of the EORTC QLQ-C30 will be used to measure mood. Participants rate the degree that each item has applied to them during the past week on a four-point Likert scale (1, not at all; 4, very much). The average of the item scores gives a raw score and the raw score will be transformed to a 0 to 100 scale. Higher scores indicate improved mood. | At 8 weeks |
