About this study

Official title: Phase II Dose Response Study of a Topical Gel Formulation of Nitroglycerin, MQX-503, in the Treatment of Raynaud's Phenomenon

The Purpose of this study is to determine the response to two different strengths of a topical gel containing nitroglycerin in patients with Raynaud's disease.

Read the detailed description

The Purpose of this clinical study is to determine, in a controlled fashion, the response to two dosage strengths of a topical gel formulation of Nitroglycerin, MQX-503, in the determination of changes in finger blood flow and skin temperature in the fingers of patients with moderate to severe primary Raynaud's phenomenon and with Raynaud's phenomenon secondary to autoimmune diseases, such as scleroderma. The dosage strength response in the treatment of the symptoms (pain, tingling, numbness) will also be monitored.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MQX-503 in people with Raynaud's Disease and Raynaud's Disease Secondary to Scleroderma, run by MediQuest Therapeutics 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 13 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 30 May 2007. 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?

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?

Measure the time required for blood flow to return to baseline after cold exposure. 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 30 May 2007.
