Current Primary Outcome Measures  ICMJE
 (submitted: September 30, 2019)
  • Knee Osteoarthritis Outcomes Scale (KOOS) pain subscale [ Time Frame: Change from Baseline Pain Severity at 12 weeks ]
    The self-reported KOOS pain subscale is sensitive to changes in knee OA symptoms, and consists of nine items scored on a Likert scale (0 [No problems] to 4 [Extreme Problems]) that ranges from 0-36, with higher values indicating greater severity.
  • Hamilton Depression Rating Scale (HAM-D) [ Time Frame: Change from Baseline Depression Severity at 12 weeks ]
    The HAM-D is clinician-administered, 21-item questionnaire, designed to rate the severity of depression in patients. Individual scores are based on the first 17 items, each with a possible score of 0-4 (0=Absent; 4=Extreme Symptoms) or 0-2 (0=Absent; 2=Frequent), yielding an overall range of 0-54. Higher scores indicate greater depression severity.
Original Primary Outcome Measures  ICMJE Same as current
Change History No Changes Posted
Current Secondary Outcome Measures  ICMJE
 (submitted: September 30, 2019)
Maximal oxygen consumption [ Time Frame: Change from Baseline Peak Maximal Oxygen Consumption at 12 weeks ]
Peak maximal oxygen consumption will be assessed while patients are walking on a treadmill, when they are respiring through a non-rebreather mask to collect expired air. Carbon dioxide and oxygen gas concentrations will be measured, and the final 20 seconds of oxygen consumption are averaged to determine peak consumption.

Descriptive Information
Brief Title  ICMJE Exercise Plus Duloxetine for Knee Osteoarthritis and Depression
Official Title  ICMJE A Feasibility and Pilot Study of Combined Treatment Protocol Using Aerobic Exercise and Duloxetine in Older Adults With Symptomatic Knee Osteoarthritis and Comorbid Depression
Brief Summary This study evaluates the addition of duloxetine to aerobic exercise in the treatment of symptomatic knee osteoarthritis and depressive symptoms in adults. All participants will receive the receive the treatment protocol, which will first be evaluated in terms of feasibility and then pilot tested.
Detailed Description Symptomatic knee osteoarthritis (OA) affects 10% of men and 13% of women 60 years or older, and depressive symptoms are common, occurring in one-fifth of these patients. Depressive symptoms worsen knee OA disease severity and are a barrier to pain management and engagement in physical activity. Guidelines recommend depression treatment in older adults with knee OA but provide no direction on how to simultaneously manage the co-occurrence of physical and mental morbidity. Treatment recommendations advise exercise to manage pain and disability and improve psychosocial health in knee OA patients; however, compliance to exercise programs is low in persons with chronic pain and disability and is only made worse by comorbid depression. Adherence is critical to the efficacy of depression treatments using exercise training, and no such exercise program has ever been designed for and tested in OA patients with co-occurring depressive symptoms in a way to enhance compliance. Duloxetine is the only antidepressant medication indicated for pain management in knee OA patients that has demonstrated efficacy and tolerability when treating depression in older adults and is a viable pharmacological complement to exercise. There are no protocols that combine treatments using interventions that affect symptoms of both knee OA and depression, and the study goals are to evaluate the feasibility of and then pilot test a protocol comprised of aerobic exercise training plus duloxetine for the treatment of symptomatic knee OA and comorbid depression.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Knee Osteoarthritis
  • Depression
Intervention  ICMJE
  • Behavioral: Aerobic exercise
    Participants with symptomatic knee osteoarthritis and depressive symptoms will be enrolled in a progressive walking program designed to reduce pain and disability and improve psychosocial health.
  • Drug: Duloxetine
    Duloxetine is an FDA-approved selective serotonin and norepinephrine reuptake inhibitor antidepressant approved for the treatment of neuropathic pain in symptomatic knee osteoarthritis as well as depression in adults. Participants with symptomatic knee osteoarthritis and depressive symptoms will receive duloxetine to decrease pain and depression severity to enhance their ability to engage in aerobic exercise.
Study Arms  ICMJE Experimental: Aerobic exercise plus Duloxetine
Participants will have a starting duloxetine dosage of 30 mg/day and be titrated up to a daily optimal dosage of 60 mg/day as tolerated during the first 12-weeks of the study. Twelve weeks after the receipt of their prescription, participants will be evaluated for the need to increase medication dosage to 90 mg/day. After duloxetine initiation, participants will be provided an exercise prescription that includes a progressive walking program aiming to achieve 50 minutes of moderate-intensity physical activity, three times per week, over 24 weeks.
Interventions:
  • Behavioral: Aerobic exercise
  • Drug: Duloxetine
