Safety and Tolerability of PRO-185

Phase 1
Completed
Conditions
Hyperemia Eye
Interventions
Registration Number
NCT05470868
Lead Sponsor
Laboratorios Sophia S.A de C.V.
Brief Summary

Phase I Study to evaluate safety and tolerability of PRO-185 (naphazoline/hypromellose) ophthalmic solution through evaluation of vital signs, ocular signs such as intraocular pressure, hyperemia and mydriasis and adverse events.

Detailed Description

A total of 22 healthy volunteers will apply PRO-185 ocular solution on both eyes QID (four times per day) for 8 days. The safety variables will include intraocular pressure, heart rate, systolic and diastolic blood pressure. Tolerability variables will include: hyperemia, mydriasis, and expected and unexpected adverse events. The presence of any of these in ≤ 20% will deem PRO-185 as safe and tolerable.

Safety evaluation through the incidence of subjects presenting an elevation \> 5 mmHg in intraocular pressure 20 minutes after administration, in comparison to baseline value.

Heart rate incrementBaseline visit, day 1(pre and post pupil dilation); Visit 1, day 3 +1 (pre and post research product application); Visit 2, day 8 (pre and post research product application); Final Visit, day 10 (+1)

Safety evaluation through the incidence of subjects presenting an elevation \> 15 beats per minute 20 minutes after administration, in comparison to baseline value.

Blood pressure incrementBaseline visit, day 1(pre and post pupil dilation); Visit 1, day 3 +1 (pre and post research product application); Visit 2, day 8 (pre and post research product application); Final Visit, day 10 (+1)
