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

This study description pertains to the ADOPT PGx Acute Pain Trial.

The overall ADOPT PGx study was 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 (this study), the Chronic Pain Trial, and the Depression Trial. Participants could enroll in only one of the three trials. Trial-specific outcomes will be compared between participants in the intervention arm and control arms who have an actionable phenotype.

Acute Pain Trial: A prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria were 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). Actionable phenotypes are defined as CYP2D6 intermediate metabolizers (IMs) and poor metabolizers (PMs) (i.e. CYP2D6 activity score ≤ 0.75) for the acute pain trial.

This study includes approximately 1,610 participants with planned/elective surgery who are anticipated to start a pain control medication with existing CPIC guidelines after their surgery.
