About this study

Official title: Translational Studies in Analgesic Pharmacology: Analgesic Synergy in Clinical Pain. A Phase 2 Study Comparing a Single Dose of a 1:1 Combination of Methadone and Morphine With Morphine Alone in Patients With Post-operative Pain.

This is a randomized Phase II study testing the effectiveness of the combination of morphine and methadone versus morphine alone in relieving pain. A second goal is to further evaluate any side effects of the combination of morphine and methadone.

Read the detailed description

Rationale: Experimental data demonstrates a profound analgesic synergy between morphine and methadone when co-administered systemically in mice. If this type of synergy can be demonstrated in clinical pain, it will be a relatively unique example of translating concepts of fundamental aspects of opioid actions seen in the laboratory to the clinical area, and provide a basis for offering new and scientifically- based analgesic regimens. This may provide better pain relief with less opioid related side effects in clinical practice.

Purpose:

This is a randomized, double blind, parallel arm Phase II study comparing a single dose of 1:1 combination of methadone and morphine with morphine alone in patients with post-operative pain.

  • The primary objective of this randomized, double blind, parallel arm Phase II study is to compare the analgesic effects of a combination of morphine and methadone with morphine alone to determine synergistic activity of mu opioid analgesics in patients with post-operative pain.
  • A second goal is to further evaluate any side effects of the combination of morphine and methadone.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Methadone and methadone and morphine in people with Pain, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Mar 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Primary Goal of This Study is to Compare the Analgesic Effects of a Combination of Morphine and Methadone With Morphine Alone to Determine Synergistic Activity of mu Opioid Analgesics in Patients With Post-operative Pain. (time frame: Time to the third request for the pain medication). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2019.
