About this study

Official title: Mechanisms of Action of Hydroxychloroquine in Reducing Risk of Type 2 Diabetes

The purpose of this study is to determine the short-term effects of the antimalarial medication, hydroxychloroquine (HCQ), compared with placebo using frequently sampled intravenous glucose tolerance testing (FSIGTT) methodology to study changes in insulin secretion and glucose tolerance in subjects at risk for developing Type 2 diabetes.

Read the detailed description

Diabetes is approaching epidemic proportions in the United States. This study evaluates the mechanisms of action of a generic drug that may have effects on glucose metabolism.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing hydroxychloroquine in people with Pre-diabetes, run by University of Pittsburgh 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 8 inclusion and 16 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 26 Feb 2016. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 29 Jan 2016). 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?

Insulin Sensitivity (time frame: 13 weeks after baseline measurement). 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 NCT01326533, 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 26 Feb 2016.
