A Depression and Opioid Pragmatic Trial in Pharmacogenetics (Acute Pain Trial) (ADOPT PGx)

March 6, 2026 updated by: Duke University

A Depression and Opioid Pragmatic Trial in Pharmacogenetics

This study is comprised of three separate pharmacogenetic trials grouped into a single protocol due to similarities in the intervention, the hypotheses, and the trial design. The three trials are the Acute Pain Trial, the Chronic Pain Trial, and the Depression Trial. Participants can enroll in only one of the three trials. All three trials were registered on ClinicalTrials.gov under NCT04445792. In July 2023 each of the three treatment trials was registered under a separate NCT# and NCT04445792 was converted to a screening record per recent guidance on master protocol research programs (MPRPs). This record is specific to the Acute Pain Trial within the ADOPT-PGx protocol.

The Acute Pain Trial is a prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria will be randomly assigned to either immediate pharmacogenetic testing and genotype-guided post-surgical opioid therapy (Intervention arm) or standard care and pharmacogenetic testing after 6 months (Control arm). The investigators will test the hypothesis that pharmacogenetic testing and genotype guided pain management therapy improves pain control after surgery in participants who's body processes some pain medicines slower than normal.

Conditions

Detailed Description

Pain and depression are conditions that impact substantial proportions of the US population. Finding safe and effective drug therapies for both conditions is challenging. In the case of treatment for acute and chronic pain, the challenge is finding effective therapy while minimizing adverse effects or opioid addiction (and the ensuing consequences). For depression, there are few clinically relevant predictors of successful treatment leading to multiple trials of inadequate therapy for some patients. Both opioid and antidepressant prescriptions can be guided by pharmacogenetics (PGx) data based on existing guidelines from the Clinical Pharmacogenetics Implementation Consortium (CPIC).

This study is designed to evaluate the impact of pharmacogenetic testing and genotype-guided pain or anti-depressant therapy on pain control or depression symptoms in a pragmatic setting.

The rationale for examining a genotype-guided approach to acute and chronic pain management is based on the importance of CYP2D6 for the bioactivation of tramadol, codeine, and hydrocodone and data from a pilot study supporting improved pain control in intermediate and poor CYP2D6 metabolizers in the genotype-guided arm who are taking these drugs at baseline. Similarly, the rationale for examining a genotype-guided approach to depression medication therapy is based on the demonstrated role of CYP2D6 in the bio inactivation and CYP2C19 oxidation of select, commonly used SSRIs. Secondly, data from industry sponsored trials support the hypothesis of improved depression symptom control in a genotype-guided arm.

Study objectives:

Determine if a genotype-guided approach to acute post-surgical pain therapy leads to improved pain control compared to usual care, as defined by a decrease in the SIA score. Secondarily, The investigators will evaluate whether this approach leads to reduced use of DEA Schedule II opioids and reduced pain intensity.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
10 Day Silverman Integrated Analgesic Assessment (SIA) Score
Time Frame: Day of surgery (baseline) to 10 days post surgery
A composite measure of pain and opioid usage, the Silverman Integrated Analgesic Assessment (SIA) score, at 10 days post-surgery in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75. The SIA has a total score range of -200 to 200, where a higher score corresponds with higher pain and opioid use.
Day of surgery (baseline) to 10 days post surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
10 Day Pain Intensity as Measured by the PROMIS Numeric Pain Rating Scale
Time Frame: 10 days post-surgery
PROMIS (Patient-Reported Outcomes Measurement Information System) Numeric Pain Rating Scale Pain intensity at 10 days post-surgery in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75. Pain was measured on a scale of 0-10, where higher scores correspond to higher levels of pain.
10 days post-surgery
Post-surgery Opioid Usage, Measured in Milligrams of Morphine Equivalents (MME) Per Day
Time Frame: Day of surgery (baseline) to 10 days post surgery
Opioid usage from surgery to 10 days post-surgery in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75.
Day of surgery (baseline) to 10 days post surgery
3 Month Prescription Pain Medication Misuse
Time Frame: 3 months post surgery
The 7-item PROMIS Prescription Pain Medication Misuse questionnaire assesses the extent to which participants experience medication misuse symptoms over the past 3 months using a 5-point Likert scale. The 7 questions are converted to a raw score, ranging from 7 to 35. Raw scores are converted to T-scores using the PROMIS conversion tables and range from 36.3 to 55.8. Higher scores reflect greater medication misuse.
3 months post surgery
1 Month PROMIS Mobility Score
Time Frame: 1 month post surgery
PROMIS mobility score at 1 month post-surgery in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75 in the adult population only. The score ranges from 15 to 75, where a higher score corresponds to higher mobility.
1 month post surgery
Number of Participants With Opioid Persistence
Time Frame: 3-6 months post-surgery, assessed at 6 months
Opioid persistence defined as a filled prescription for an opioid medication 3-6 months post-surgery in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75.
3-6 months post-surgery, assessed at 6 months
Participants With Drug-Gene Concordance
Time Frame: Within 10 days post-surgery
Drug-Gene Concordance defined as an agreement between the Pharmacogenomics (PGx) Test and the prescribed opioids post surgery for pain management in participants who have a genotypic or pheno-converted CYP2D6 activity score ≤ 0.75
Within 10 days post-surgery
