About this study

Official title: Vision and Inflammation Study Testing Anti-acarid Therapeutics (VISTA-1): A Phase 2, Controlled, Double Blind, Randomized and Multicenter Study to Compare Efficacy and Safety of a Novel Topical Therapy (APT-001, Spinosad 1.8%) in Patients With Blepharitis.

The purpose of this study is to establish the clinical efficacy of APT-001 topical therapy 1.8% in patients with blepharitis as compared to its vehicle control, and to establish that the therapeutic is safe and generally well tolerated by patients.

Read the detailed description

This Phase 2 study is a randomized, controlled, double-blind trial to compare the safety and efficacy of APT-001 1.8% to vehicle control for the treatment of blepharitis. The primary objective of the study is to compare the safety and efficacy of APT-001 compared to its vehicle from Day 1 to Day 43 in patients with blepharitis. The primary efficacy endpoint will be cure based upon collarettes. Safety will be determined by assessing adverse effects related to the treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing APT-001 topical ophthalmic ointment (spinosad) in people with Blepharitis, run by Aperta Biosciences, LLC at 2 sites in Guatemala.

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 6 inclusion and 9 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 27 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Guatemala. 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 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?

Collarette Cure (time frame: From enrollment to the end of treatment at 6 weeks). 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 27 Oct 2026.
