NCT03906721

Brief Summary

The use of conditioning open-label placebo (COLP) will be studied as a dose extension method to lower opioid dosage in patients with spinal cord injury, polytrauma, and burn injury. The goal is to provide the same level of pain relief with a reduced opioid dose to diminish adverse effects as well as the risk of addiction associated with narcotic treatment.

Outcome Measures

Primary Outcomes (1)

  • Morphine Milligram Equivalents (MME)

    Morphine Milligram Equivalents (MME) are used to standardize opioid exposure by expressing the analgesic potency of different opioids relative to morphine. MME is calculated by multiplying the prescribed opioid dose by the daily frequency of administration and then by an opioid-specific conversion factor. The resulting value is expressed as milligrams of morphine equivalents (mg MME). Values range from 0 mg MME upward, with higher values indicating greater opioid exposure, which has been associated with an increased risk of adverse clinical outcomes.

    6 days

Secondary Outcomes (6)

  • Visual Analog Scale for Pain (VAS)

    Day 6

  • Spinal Cord Injury - Quality of Life Measurement System (SCI-QOL)

    Day 1 and Day 6

  • Numerical Opioid Side Effects (NOSE)

    Change in NOSE score from Day 1 and Day 6

  • Electroencephalography - Power Spectrum

    Power spectrum Change from Day 1 to Day 6

  • Near-infrared Spectroscopy (NIRS)

    Day 1 and Day 6

  • +1 more secondary outcomes

Study Arms (2)

Conditioning & Open-Label Placebo (COLP)

EXPERIMENTAL

Days 1 to 3 will include the acquisition phase where oxycodone will be prescribed on a schedule of 3-4 times per day and paired with open-placebo and smelling the essential oil. Days 4 to 6 will be the evoked phase, and patients will receive full oxycodone dosage on alternating days with open placebo and smelling the essential oil.

Drug: PlaceboDrug: OxycodoneOther: Essential Oil

OTHER

Drug: Oxycodone

  • A history of bipolar disorder or psychosis, as self-reported,
  • Any substantial decrease in alertness, language reception, or attention that might interfere with understanding,
  • Current usage of narcotic medication with dosage higher than 120 mg of morphine equivalent or 80 mg of a short-acting oxycodone,
  • Current use of ventilator,
  • Compromised medical status due to uncontrolled pathology such as cancer, heart failure, kidney or liver insufficiency, or any other condition which jeopardises patient's participation to the study
  • Pregnancy or breastfeeding. Females in childbearing age who are eligible to participate in the study, will be tested for pregnancy by serum hCG test

Model Details: This is a randomized single-blind open-label placebo clinical trial. 60 inpatients will be included from SRH, both men and women aged 18 or older with traumatic and non-traumatic SCI (ASIA A-D), polytrauma and burn injury patients from the Comprehensive Rehabilitation Program at Spaulding Rehabilitation Hospital who have; above, at, or sub-lesional neuropathic pain and/or nociceptive pain (musculoskeletal or visceral) that is moderate or severe in nature (average VAS scale score of 4 or greater at time of enrollment). All subjects must meet clinical criteria for the use of opioids as a treatment for pain management.
