Ended Therapeutic exploratory (Phase II) Dry Eye

A study to evaluate safety and efficacy of two different concentrations of a new formulation of Recombinant Human Nerve Growth Factor (rhNGF) eye drop solution in patients with Dry Eye Disease.

EU CTIS ID: 2023-507561-26-00

What this study is testing

To evaluate the efficacy of 5 mcg/mL and 10 mcg/mL concentrations of the new formulation of rhNGF ophthalmic solution versus vehicle, in order to demonstrate superiority of at least one of the concentrations over vehicle in the improvement of ocular symptoms of dry eye in patients with dry eye disease (DED).
