Vancouver, British Columbia–(Newsfile Corp. - February 26, 2026) - DiagnosTear Technologies Inc. (CSE: DTR) (FSE: X8F) (“DiagnosTear” or the “Company”), a fast-growing innovator in point-of-care ocular diagnostics, is pleased to announce that it has obtained all required regulatory and ethics approvals to proceed with the clinical study of TeaRx™ Red Eye previously announced in a press release dated December 2, 2025.

As previously disclosed, the Company initiated a collaboration with AlyaTec, a leading Contract Research Organization (CRO) specializing in allergy and environmental diseases, to conduct a clinical study designed to advance the analytical validation and FDA submission pathway of the TeaRx™ Red Eye diagnostic platform.

The Company has now received:

**Approval from** **ANSM **(_Agence Nationale de Sécurité du Médicament et des Produits de Santé_), the French National Agency for Medicines and Health Products Safety.

**A favourable opinion from the** **French Ethics Committee** (Comité de Protection des Personnes Sud Méditerranée III), which reviewed the study protocol and **issued a positive decision following its plenary session**.

These approvals enable the clinical study to formally proceed.

In addition, AlyaTec has notified the Company that operational readiness has been achieved and that patient recruitment and sampling has commenced.

This study is designed to evaluate tear samples collected from documented allergy patients before and after controlled ocular allergy provocation, with the goal of finalizing the analytical validation of total tear IgE as a key biomarker for Allergic Conjunctivitis and further strengthening the scientific and regulatory pathway of TeaRx™ Red Eye, as previously described. The significance of a successful outcome in this study would be validation of the ability of the TeaRx™ Red Eye test to identify active ocular allergy by total tear IgE.

Dr. Shimon Gross, CEO of DiagnosTear, commented: “Obtaining both regulatory and ethics approvals represents a significant milestone for our Red Eye program and reflects the strong scientific and clinical foundation of this study. With recruitment now underway, we are entering an important execution phase that moves us closer to completing the analytical validation of our multi-biomarker diagnostic platform.”

Dr. Gross added: “We are pleased to see the rapid operational progress at AlyaTec and the initiation of patient screening. We believe these developments meaningfully advance our regulatory strategy and support our broader commercialization roadmap.”
