About this study

Prospective, double-masked, randomized, multi-center, active-controlled, parallel-group, 3-month study assessing the safety and ocular hypotensive efficacy of TearClear latanoprost Ophthalmic Solution, 0.005% (TC-002) compared to latanoprost Ophthalmic Solution, 0.005% (LAT) in subjects with elevated intraocular pressure at approximately 20 study sites located in the United States

Read the detailed description

This is a Phase 3, randomized, investigator-masked, multicenter, parallel-group trial comparing two ophthalmic solution formulations of latanoprost at a fixed dose of 0.005% administered once daily (QD) for 12 weeks.

Approximately 300 subjects will be randomized in this study at approximately 20 sites in the United States (US).

Treatment assignments will be masked to TearClear, study subjects, Investigators and site staff. Because the container closure for the investigational product is different, this study will use an unmasked dosing coordinator at each study site. All clinical trial supplies will be masked by using carton boxes to mask the appearance of the immediate container closure.

At approximately 2 select sites, approximately10% of total randomized subjects will have systemic PK labs drawn.

The study involves 7 clinic visits, including Screening (Visit 1), Randomization (Visit 2) and treatment visits (Visits 3, 5 and 7, during which ophthalmic assessments will occur and IOP will be assessed diurnally. There will be two interim IP dispensation visits (Visits 4 and 6).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Latanoprost ophthalmic solution, 0.005%Drug

    Commercially available, FDA-approved generic latanoprost ophthalmic solution, 0.005% (LAT) without modification will be used as the active control

  • TC-002 latanoprost ophthalmic solution, 0.005%Drug

    TC-002 is formulated using the commercially available latanoprost drug substance; delivered drop to the eye is preservative-free.

What is being measured

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

  1. Primary efficacy endpoint is the difference in mean change from baseline (CFB) in IOP

    Measured: Weeks 2, 6, and 12 at 8:00 AM, 10:00 AM, and 4:00 PM.

Secondary outcomes (1)
  1. Secondary efficacy endpoints include diurnal (average of 8:00 AM, 10:00 AM, and 4:00 PM measurements) IOP

    Measured: Weeks 2, 6, and 12.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Latanoprost ophthalmic solution, 0.005% and TC-002 latanoprost ophthalmic solution, 0.005% in people with Elevated Intraocular Pressure, run by TearClear Corp at 20 sites 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 10 inclusion and 27 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: status not confirmed, as of the sponsor's last update on 25 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Primary efficacy endpoint is the difference in mean change from baseline (CFB) in IOP (time frame: Weeks 2, 6, and 12 at 8:00 AM, 10:00 AM, and 4:00 PM.). 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 25 May 2022.
