About this study

Official title: A Randomized, Double-Blind, Triple-Dummy, Single-Dose, Four-Way Crossover Study to Determine the Relative Bioavailability, Pharmacodynamic Effects, and Safety of Equivalent Doses of Whole and Crushed ALO-01 Versus Morphine IR in Opioid Experienced, Non-Dependent Subjects

The purpose of the study is to determine the relative pharmacodynamic effects and safety of crushed and whole ALO-01 compared to MSIR and to Placebo, and of crushed ALO-01 to whole ALO-01; to determine the relative bioavailability of plasma morphine from crushed and whole ALO-01 compared to MSIR, and from crushed ALO-01 to whole ALO-01; and to determine the relative bioavailability of plasma naltrexone and 6-β-naltrexol from crushed ALO-01 to whole ALO-01.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ALO-01 and MSIR in people with Healthy, run by Pfizer at 1 site in Canada.

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 10 inclusion and 19 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 16 Sep 2013. 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 Canada. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Pupillometry - Minimum Apparent Post-dose Pupil Diameter (time frame: Up to 24 hours post dosing). The study lists 8 primary outcomes in all. 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 16 Sep 2013.
