Clinical Trial Summary

The study objective is to assess the efficacy and safety of cenegermin (rhNGF) ophthalmic solution at 20 mcg/mL concentration administered three times daily for 4 weeks in patients with severe Sjogren's dry eye disease (DED) who are under chronic treatment with topical Cyclosporine A (CsA).

Clinical Trial Description

This is a 4 week phase III, multicenter, double-masked, vehicle-controlled study to evaluate safety and efficacy of cenegermin ophthalmic solution at 20 mcg/mL solution versus vehicle, in patients with severe Sjogren's dry eye disease.

During the screening all procedures for inclusion will be performed. From the day of screening the patients will stop any kind of further treatment, except CsA and commercially available preservative free artificial tears provided by Sponsor for a period of 7 days and 9 days. At the end of the washout period , patients meeting the entry criteria for this study will be randomized 1:1 and treated for 4 weeks with either cenegermin ophthalmic solution 20 mcg/mL TID or vehicle TID.

In addition to topical CsA eye drops (both groups will continue with topical CsA eye drops, or other topical ophthalmic treatment of the same class), during the 4 weeks of masked treatment only the administration of IMP is allowed. During the follow up period, the patient can administer additional artificial tear eye drops, provided by Sponsor, only if strictly needed, and must document in the patient's diary the number of additional drops administered for each eye. Patients will then be followed up for efficacy and safety endpoints until week 16 and for safety endpoints until week 24. The total duration of the study is 25 weeks including 1 week of screening. ;
