Evaluation of Safety and Efficacy of rhNGF in Patients With Stage 2 and 3 Neurotrophic Keratitis. — REPARO  

Corneal Ulcer Clinical Trial

Official title:
An 8-week Phase I/II, Multicenter, Randomized, Double-masked, Vehicle Controlled Parallel Group Study to Evaluate the Safety and Efficacy of Two Doses of Recombinant Human Nerve Growth Factor in Patients With Stage 2 and 3 of NK

Clinical Trial Summary

This study is aimed at assessing the safety and the efficacy of two dose regimens of recombinant human nerve growth factor (rhNGF) eye drops solution compared to vehicle for inducing a complete healing of stage 2 (persistent epithelial defect) and 3 (corneal ulcer) neurotrophic keratitis

Clinical Trial Description

The primary objective of this study is to assess the safety and the efficacy of two dose regimens (10 µg/ml or 20 µg/ml 6 times a day) of recombinant human nerve growth factor (rhNGF) eye drops solution compared to vehicle for inducing a complete healing of stage 2 (persistent epithelial defect) and 3 (corneal ulcer) neurotrophic keratitis (NK) as measured by the Reading Center evaluating the clinical pictures of corneal fluorescein staining. Secondary objectives of the study are to assess the duration of complete healing, improvement in visual acuity and improvement in corneal sensitivity following treatment with rhNGF eye drops solution This is a combined phase I/II study. The phase I and II segments of the study will be conducted as an 8 week, randomized, double-masked, vehicle controlled, parallel group study (referred to as the controlled treatment period) followed by a 48 or 56 week follow-up period The design of the phase I and phase II segments of the study are identical with the exception that in the phase I segment of the study the randomization scheme is different and patients will be followed with additional safety assessments and blood samples for PK (pharmacokinetic) profiling In the ascending dose Phase I segment of the study two doses of rhNGF 10 and 20 µg/ml will be evaluated in a sequential manner ;
