Clinical Trial Summary

Knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Depression and obesity are highly comorbid among knee osteoarthritis patients, and the combination of obesity and depression is associated with decreased physical activity, higher pain and disability, and more rapid cartilage degradation. Depression, obesity and osteoarthritis exacerbate one another and share a common pathophysiology involving systemic inflammation and pro-inflammatory cytokines, reflecting a complex mind-body interaction. Current treatments for knee osteoarthritis offer little to no benefit over placebo, and do not emphasize mind-body practices or physical activity to target the underlying pathophysiology. Mind-body interventions to lessen depressive symptoms and increase physical activity offer the ability to target biological, mechanical and psychological mechanisms of osteoarthritis progression in this high-risk subset. The long-term goals are to evaluate the mechanisms by which the Relaxation Response Resiliency Program (3RP) delivered via telehealth, and adapted for patients with depression, obesity and knee OA (GetHealthy-OA) promotes increases in physical activity and improved subjective and objective aspects of knee health. The overarching hypothesis is that the synergistic interaction between mindfulness, adaptive thinking, positive psychology and healthy living skills of the GetHealthy-OA will reduce pro-inflammatory cytokine expression while also promoting optimal mechanical loading of the cartilage thereby slowing the progression of symptomatic knee osteoarthritis. This study aims to adapt the 3RP for the needs of knee osteoarthritis patients with depression and obesity with a focus of increasing physical activity, and iteratively establish the feasibility, credibility and acceptability of the programs and research procedures.

Clinical Trial Description

The conceptual model of adaptation of the general 3RP to obese osteoarthritis patients with depression that specifically target improved function through combining mind body skills with physical activity, and recommendations of multimodal programs to improve outcomes in chronic pain clinical trials. Adaptations of the multimodal general 3RP will be done consistent with theoretical models of the fear-avoidance model of pain, cognitive model of pain and depression, acceptance and commitment therapy, mindfulness, and positive psychology. The goal is to help patients engage in activities that are meaningful and mapped to each individual's level of functioning and life circumstance through the use of quota-based pacing through adaptation of skills to directly address improved mood, healthy lifestyle (sleep, diet), correction of knee osteoarthritis misconceptions, and use of relaxation response elicitation and positive psychology skills to promote awareness and calm during activities, even when these are painful. The guiding hypothesis is that the synergistic interaction between mindfulness, adaptive thinking, positive psychology, physical activity and healthy living skills of the GetHealthy-OA reduces pro-inflammatory cytokine expression while also promoting optimal mechanical loading of the cartilage thus slowing the progression of symptomatic knee OA. In this project the 3RP will be iteratively adapted for the needs of knee osteoarthritis patients with depression and obesity with a focus on gradual increases in physical activity measured with accelerometers and establish feasibility markers for the program and procedures. A pilot randomized controlled trial of the GetHealthy-OA versus a time- and attention-matched health enhancement control will be performed to assess the feasibility of recruitment procedures, feasibility and acceptability of the GetHealthy-OA and control, and data collection procedures by group. A pilot randomized controlled trial (N=60 participants) of the GetHealthy-OA with a time and attention matched health enhancement control will be performed. The end goal of the pilot RCT is not to assess the efficacy of the GetHealthy-OA but rather to assess the feasibility of recruitment procedures (screening, eligibility, enrollment rates), feasibility and acceptability of the GetHealthy-OA and control intervention (adherence, retention, fidelity, satisfaction, group telehealth delivery, and data collection procedures by group (adherence, satisfaction, blood and urine biomarker data). A single blind pilot feasibility randomized controlled trial with a time, dose and attention matched health enhancement control will be conducted (N=60; approximately 5 GetHealthy-OA groups and 5 control, 6-8 per group). Participants will be randomized in a 1:1 design using a randomization scheme developed by the statistician. Research procedures will be identical for patients in GetHealthy-OA and control. The study will yield information on how participants might engage differently with the intervention and control, definitive information on feasibility and acceptability and signal of improvement in the intervention before investment of resources in the full randomized controlled trial. The GetHealthy-OA refined based on exit interviews and surveys. The control group will have the same format as the GetHealthy-OA, and the control group follows the format of the Health Enhancement Program. A pain specific adaptation of this program for chronic pain exists. This program will be adapted for the specific needs of patients with knee osteoarthritis. ;
