About this study
Official title: A Single Center, Randomized, Double-masked, Vehicle-controlled Phase 2 Study Evaluating the Safety and Efficacy of TL-925 Ophthalmic Emulsion 0.1% Compared to Vehicle for the Treatment of Allergic Conjunctivitis in the Conjunctival Allergen Challenge (Ora-CAC®) Model
In this prospective Phase 2, single-center, randomized, double-masked, placebo-controlled study, approximately 70 subjects with allergic conjunctivitis will be randomized 1:1 to receive either TL-925 or placebo as topical ophthalmic eye drops administered bilaterally.
The study comprises of a screening and treatment period using the conjunctival allergen challenge model to evaluate TL-925 for the treatment of allergic conjunctivitis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TL-925Drug
TL-925 is an eye drop.
PlaceboDrug
The composition of the placebo is identical to the active formulation except for the exclusion of the active ingredient.
| Study group | Role | What they receive |
|---|---|---|
| TL-925 Arm | Active comparator | Subjects will be dosed in clinic on days of dosing. Receives: Drug: TL-925 |
| Placebo Arm | Placebo comparator | Subjects will be dosed in clinic on days of dosing. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ocular itching
Ocular itching score will be reported by the subject at 3 timepoints after CAC at Visits 4, 5 and 6. Assessments were reported using a 0-4 numerical scale (0 = none and 4 = incapacitating itch with an irresistible urge to rub).
Measured: 3, 5 and 7 minutes after CAC
Conjunctival redness
Conjunctival redness will be assessed by the investigator at 3 timepoints after CAC at Visits 4, 5 and 6. Assessments were completed using a 0-4 numerical scale (0 = none and 4 = extremely severe).
Measured: 7, 15 and 20 minutes after CAC

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing TL-925 in people with Allergic Conjunctivitis, run by Telios Pharma, Inc. 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 5 inclusion and 3 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 1 Dec 2023. 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 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact John Mei ((650) 542-0136, jmei@teliospharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ocular itching (time frame: 3, 5 and 7 minutes after CAC). The study lists 2 primary outcomes in all. 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 1 Dec 2023.
