What this trial studies

This Phase 2 interventional trial compares T1695 with ciclosporin in children and adolescents (ages 4 to less than 18) who have moderate to severe vernal keratoconjunctivitis. Participants will be assigned to receive either T1695 or ciclosporin eye treatment and followed with slit-lamp examinations, best-corrected visual acuity testing, corneal fluorescein staining using a modified Oxford scale, and Bonini grading of disease severity. Safety and effectiveness outcomes will be compared between groups over the study period to see if T1695 controls inflammation and symptoms as well as or better than ciclosporin. The trial is being conducted at specialized eye hospitals in India and requires informed consent from participants and guardians.

Who should consider this trial

Good fit: Children and adolescents aged 4 to less than 18 years with bilateral Bonini grade 3 or 4 vernal keratoconjunctivitis and parental/guardian consent would be eligible candidates.

Not a fit: Patients with mild VKC, adults, or those with other ocular conditions or protocol exclusions are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, T1695 could provide better symptom control or fewer side effects than ciclosporin for children with moderate to severe VKC.

How similar studies have performed: Topical ciclosporin has established benefit in VKC, while T1695 is a novel agent with limited published clinical data and is being tested directly against ciclosporin.
