Trial Summary

What is the purpose of this trial?

There is an urgent public health need to reduce reliance on opioids for effective long-term pain management, particularly in knee osteoarthritis (KOA). This effectiveness trial will compare commonly recommended treatments to reduce pain and functional limitations in KOA.These results will lead to improved patient selection for treatment and inform evidence based guidelines by offering well-tested, effective, non-surgical alternatives.

Treatment Details

Interventions

  • Best Practices
  • Duloxetine
  • Intra-Articular Injection
  • Nerve Procedure with long acting blocks
  • Nerve Procedure with nerve ablation
  • Pain Coping Skills Training
Trial Overview The trial tests several non-surgical treatments to manage long-term pain and improve function in people with knee osteoarthritis. Treatments include Duloxetine (a medication), nerve procedures using either long-acting blocks or ablation techniques (nerve destruction), best practice care strategies, intra-articular injections (directly into the joint), and training to develop skills for coping with pain.
Participant Groups
6Treatment groups
Active Control
Group I: Phase 1: Best Practices + Duloxetine + Pain coping skillsActive Control3 Interventions
Participants will receive Duloxetine, pain coping skills training, and a prescription for guideline-recommended treatments for knee osteoarthritis, i.e., Best Practices. Best Practices can include topical or oral nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen; physical therapy that may include aquatherapy; integrative treatments such as acupuncture, yoga, or a structured exercise program; and other non-invasive treatments. Phase 1 ended enrollment on April 12, 2024.
Group II: Phase 1: Best Practices + DuloxetineActive Control2 Interventions
Participants will receive Duloxetine and a prescription for guideline-recommended treatments for knee osteoarthritis, i.e., Best Practices. Best Practices can include topical or oral nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen; physical therapy that may include aquatherapy; integrative treatments such as acupuncture, yoga, or a structured exercise program; and other non-invasive treatments. Phase 1 ended enrollment on April 12, 2024.
Group III: Phase 1: Best PracticesActive Control1 Intervention
Participants will receive a prescription for guideline-recommended treatments for knee osteoarthritis, i.e., Best Practices. Best Practices can include topical or oral nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen; physical therapy that may include aquatherapy; integrative treatments such as acupuncture, yoga, or a structured exercise program; and other non-invasive treatments. Based on the pre-specified stopping rules described in Protocol section 13.2, the DSMB advised ceasing enrollment into Arm 1A (Best Practices). This recommendation was accepted by the sponsor and study investigators. Arm 1A (Best Practices) was closed on 11/29/2023.
Group IV: Phase 2: Intra-Articular Injection (HA+)Active Control1 Intervention
Participants will receive an intra-articular injection of hyaluronic acid mixed with steroid and bupivacaine. Phase 2 ended enrollment on October 24, 2024.
Group V: Phase 2: Nerve Procedure: Long Acting BlocksActive Control1 Intervention
Participants will receive a nerve blocking procedure, long-acting local anesthetic, and steroid injection. Phase 2 ended enrollment on October 24, 2024.
Group VI: Phase 2: Nerve Procedure: Nerve AblationActive Control1 Intervention
Participants will receive a nerve ablation procedure and steroid injection. Phase 2 ended enrollment on October 24, 2024.
