About this study
Official title: An Open-Label, Rising Multiple-Dose, Multi-Center Study to Evaluate the Safety and Efficacy of Topically Applied AN2690 5.0% and 7.5% Solution for the Treatment of Adult Subjects With Onychomycosis of the Great Toenail
The purpose of the study is to determine the safety and efficacy of 5.0% and 7.5% AN2690 Solution in the treatment of distal, subungual onychomycosis of the great target toenail.
Read the detailed description
The first group of 30 protocol-qualified subjects will be assigned to Treatment Group 1 and given 5% AN2690 Solution. Provided that there is adequate evidence of clinical safety after two weeks of dosing with 5% AN2690 Solution, a second group of 30 protocol-qualified subjects will be assigned to Treatment Group 2 and given 7.5% AN2690 Solution. A third group of 30 subjects will be enrolled and assigned the highest safe concentration of AN2690 evaluated in this study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing AN2690 Solution, 5.0% and AN2690 Solution, 7.5% in people with Onychomycosis, run by Pfizer at 9 sites in Mexico.
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 7 inclusion and 22 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 14 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in Mexico. 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?
A calculated endpoint of treatment response at Day 180 comprised of the ISGA, clear nail growth and fungal culture results (time frame: Day 180). 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 14 Nov 2018.
