Outcome results

Primary

Number of Participants With a Reduction in Neurotrophic the Keratitis/Ulcer Area on Day28

Reduction in neurotrophic ulcer/keratitis area of 50% or more

Time frame: Day 28

Population: Modified Intent to treat (m-ITT): All randomised patients received at least 1 IMP dose, with at least 1 baseline and 1 post-baseline efficacy assessment.~For the primary outcome measure, 4 patients (2 in the T4020 and Vehicle groups) had no data for the reduction from baseline of corneal ulcer/keratitis area and were not included in this analysis
