Details and patient eligibility

About

This is to characterize STN1013800 active ingredient bioavailability following multiple-dose ocular administration of STN1013800 to both eyes in healthy adults.

It is a PK study with screening period of up to 28 days + dosing period of 7 days + Follow-up period of 2 days.

At present, there are no medicines for the treatment of acquired blepharoptosis in China.

Therefore, efficacy and safety phase III study is also currently being conducted.
