NCT ID: NCT06352541

Last Updated: 2025-07-11

Basic Information

• Recruitment Status: NOT_YET_RECRUITING
• Clinical Phase: PHASE1
• Total Enrollment: 28 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-09-30
• Study Completion Date: 2025-12-30

Brief Summary

This is a phase I study evaluating safety and tolerability through the incidence of unexpected adverse events and IOP measurement, as well as through the incidence of stinging after its administration, compared to placebo.

Detailed Description

The variables to be evaluated include:

Primary (safety):

• Unexpected adverse events
• IOP

Primary (tolerability):

• Stinging

Secondary (safety):

• Expected and related adverse events
• BCVA
• Ocular surface stining

Secondary (tolerability):

• Other ocular symptoms (foreign body sensation and tearing)

The operational definition states a difference under 15% in order to consider non inferior the safety and tolerability profile of PRO-232 compared to placebo.
