Phase 3
Active, not recruiting
Conditions
Pterygium
Interventions
Drug: Vehicle
Registration Number
NCT05456425
Lead Sponsor
Cloudbreak Therapeutics, LLC
Brief Summary

The objective is to evaluate the safety and efficacy of low dose and high dose CBT-001 eye drop dosed twice daily for 24 months compared to vehicle in reducing conjunctival hyperemia and preventing pterygium progression in eyes with pterygia.

Detailed Description

Clinical Hypotheses:

1. CBT-001 dosed twice daily is more effective than vehicle in:

* Reducing conjunctival hyperemia by demonstrating a statistically significant difference and clinically relevant improvement in the mean severity grade change from baseline.

* Preventing pterygium progression, by demonstrating a statistically significant and clinically relevant improvement on drug vs vehicle mean difference in the change in pterygium length from baseline.

2. CBT-001 dosed twice daily maintains the above efficacies and has an acceptable ocular and systemic safety and tolerability profile when administered topically.
