Open-label Conditioning Therapy for Peri-operative Pain Management in Head and Neck Cancer Patients
In Brief
A clinical study evaluating Conditioned open-label placebo (COLP) and Surveys about pain, opioid use and depression symptoms for Postoperative Pain and Opioid Use. Completed, enrolled 9 participants across 1 site.
Detailed Summary
The opioid epidemic is a considerable problem in the United States, and prescription opioids significantly contribute to the epidemic. Head and neck cancer (HNC) patients are inherently at increased risk for opioid dependence as surgical treatment can cause significant pain and up to 50% of patients also suffer from psychiatric comorbidities. Novel methods are needed to decrease opioid consumption following HNC surgeries to limit the risk of chronic opioid dependence in these patients. Conditioning therapy with placebo aims to elicit a classically conditioned response to an inactive medication through consistent pairing of the medication with a neutral stimulus (i.e. an odor) and has been shown to be effective for decreasing the amount of active drug require for certain clinical responses, including for acute pain. However, studies have not been completed for the treatment of acute pain in the inpatient post-operative setting. The overall goal of this pilot study is to determine the feasibility and effectiveness of conditioned open-label placebo (COLP) as an adjunct for post-operative pain management in complex head and neck cancer patients. This randomized, controlled, open-label trial will specifically compare post-operative opioid consumption and pain scales between patients receiving multimodal analgesia along with conditioned open-label placebo (COLP group) to those receiving multimodal analgesia, alone (Treatment as usual group). Findings from this study will determine the efficacy of COLP as an innovative approach to decrease opioid consumption and improve pain control in head and neck cancer patients and will provide rationale for development of future large scale trials.

Timeline
Interventions
Placebo oxycodone will be formulated to have the same physical appearance as liquid oxycodone and will be dispensed by the inpatient pharmacy and administered by the nursing staff. At all times that oxycodone or placebo medication is administered on post-operative day (POD) 1-5, the patient will undergo conditioning via exposure to a clove oil scent: 1. Conditioning (i.e. exposure to clove oil scent) with each dose of oxycodone medication on POD 1-5. 2. Scheduled placebo oxycodone medication paired with conditioning (i.e. exposure to clove oil scent) 3 times per day on POD 2-5.
Surveys before surgery: Within 1 week prior to surgery, patients complete surveys about pain levels, opioid consumption, understanding of placebo effect and symptoms of depression. Surveys after surgery: Through 6-months after surgery, patients complete surveys about pain levels, opioid consumption, side effects of opioids and symptoms of depression.
