Trial summary

The goal of the proposed research is to improve the effectiveness of treatments for opioid and for nicotine dependence by testing a novel pharmacological strategy. Specifically, pioglitazone, a peroxisome proliferator-activated gamma receptor (PPARγ) agonist, will be used as an adjunct to agonist-based treatment. Read more about this study

About this study

Official title: Effects of Pioglitazone, a PPARγ Agonist, on the Abuse Liability of Heroin and of Nicotine

The goal of the proposed research is to improve the effectiveness of treatments for opioid and for nicotine dependence by testing a novel pharmacological strategy. Specifically, pioglitazone, a peroxisome proliferator-activated gamma receptor (PPARγ) agonist, will be used as an adjunct to agonist-based treatment.

Read the detailed description

Although treatments for opioid and for nicotine dependence exist, these medications are not universally effective as many patients are unable to stop using or relapse rapidly, suggesting that treatment with a single agent alone is insufficient to facilitate cessation of use in many patients. Targeting additional pathways that may contribute to the maintenance of drug-taking behaviors or relapse may be a more effective strategy to treat individuals resistant to first-line approaches.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Drug's Break Point

    Number of operant responses (mouse clicks) participants were willing to provide in order to receive the drug under investigation (heroin or nicotine). The Breakpoint is the point at which participants stopped responding for the drug, i.e., the total number of clicks they were willing to provide in order to receive the drug.

    Measured: Following 2 weeks of Pioglitazone (PIO) maintenance.

Secondary outcomes (1)
  1. Measures of Subjective Drug Effects Most Commonly Indicative of Abuse Liability.

    Visual analog scale ratings of "Liking" reported by the participant will be the primary endpoint (0-100 mm, 0=Not at all, 100=Extremely).

    Measured: Following 2 weeks of Pioglitazone (PIO) maintenance.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing PIO in people with Heroin Dependence and Nicotine Dependence, run by New York State Psychiatric Institute 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 3 inclusion and 2 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: stopped early, as of the sponsor's last update on 13 Jul 2017. 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. 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?

Yes. Results are posted in the registry (first posted 13 Jul 2017). 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?

Drug's Break Point (time frame: Following 2 weeks of Pioglitazone (PIO) maintenance.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01395797, which also lists 1 linked publication.

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 13 Jul 2017.
