Trial summary

This study will investigate the effects of acute morphine administration on taste acuity and how much a person eats. It is hypothesized that there will be a dose dependent decrease in taste acuity and dose dependent increase in food intake associated with acute morphine administration. Read more about this study

About this study

This study will investigate the effects of acute morphine administration on taste acuity and how much a person eats. It is hypothesized that there will be a dose dependent decrease in taste acuity and dose dependent increase in food intake associated with acute morphine administration. Knowledge from this study will impact the future of feeding behavior and obesity research in the general population. Results will also promote exploration of the long-term effect of opioid abuse on taste acuity and feeding behavior in substance abusing populations.

What is being measured

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

  1. Taste

    The primary outcome variable will be the taste acuity profile, which includes the taste detection threshold, recognition threshold, magnitude estimation, and hedonic response.

    Measured: 3 hours after dose administration

Secondary outcomes (1)
  1. Calories

    The secondary outcome measure will be the amount of calories consumed over a 2 hours period following the drug administration.

    Measured: 6 hours after dose administration

Questions about this trial

What is this clinical trial studying?

A study testing taste acuity assessment and Recorded meal in people with Taste Sweet and Taste Salty, run by Johns Hopkins University 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 2 inclusion and 8 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 29 May 2014. 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.

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?

Taste (time frame: 3 hours after dose administration). 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 29 May 2014.
