Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The overall objective is to develop a patient oriented research program to efficiently evaluate the effects of pharmacogenetic variants on the dose-response relationships and safety of opioids and non-opioid analgesics. If an opioid regimen can be created that produces excellent opioid analgesia with minimal toxicity related to supratherapeutic opioid concentrations (i.e., ventilatory depression), other non-opioid analgesics (i.e., gabapentin/pregabalin, ketamine, lidocaine, cyclooxygenase inhibitors, etc.) that may decrease preoperative opioid requirements can be more efficiently and safely evaluated. These interventions may limit the opioid related toxicities related to effect site concentrations that are below those required when opioids are the predominant analgesic, such as opioid related ileus. Methadone's slow elimination clearance and limited pharmacokinetic drug-drug interactions make it an attractive perioperative opioid. The first step towards personalized opioid analgesia is to determine the effect of common pharmacogenetic variants that affect either methadone metabolism (CYP2B6) or opioid elimination.

Investigators

The overall officials registered on this study. Names that resolve to a FindMyKOL profile link to it; the rest are shown as registered.

A profile link is shown only when the registered name resolves to a person record with a confident, namesake-checked match; ambiguous names stay unlinked.

Sites

1 registered facility, with the per-site recruitment status where the registry publishes one. ClinicalTrials.gov does not publish per-site enrollment counts.

United States
  • Northwestern Memorial Hospital

    Chicago, Illinois, United States

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
