Clinical Trial Summary

Primary objectives - To compare the efficacy of cenegermin vs vehicle in Schirmer I test (without anaesthesia) >10mm/5min at Week 4 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in Symptom Assessment in Dry Eye questionnaire (SANDE) global score at Week 12 by testing the superiority. Secondary objectives - To compare the efficacy of cenegermin vs vehicle in Schirmer I test at Week 4, 8, 12 and 16 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in Cornea and conjunctiva vital staining with fluorescein (National Eye Institute [NEI] scales) at Week 4, 8, 12 and 16 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in Tear Film Break-Up Time (TFBUT) at Week 4, 8, 12 and 16 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in SANDE scores at Week 8, 12 and 16 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in worsening in symptom scores (SANDE) and/or NEI score at Week 4 by testing the superiority. - To compare the efficacy of cenegermin vs vehicle in impact of dry eye on everyday life (IDEEL) questionnaire at Week 4, 8, 12 and 16 by testing the superiority.

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 and exclusion were performed. From the day of screening the patients stopped any kind of further treatment, except commercially available preservative free artificial tears provided by Sponsor. At the end of the wash out period, patients meeting the entry criteria for this study were randomized 1:1 and treated for 4 weeks with either cenegermin ophthalmic solution 20 mcg/mL TID or vehicle TID. During the 4 weeks of masked treatment only the administration of IMP was allowed. During the follow up period, the patient could administer additional artificial tear eye drops, provided by Sponsor, only if strictly needed, and should document in the patient's diary the number of additional drops administered for each eye. Patients were then followed up for efficacy and safety endpoints until week 16 and for safety endpoints until week 24. The total duration of the study was 25 weeks including 1 week of screening. ;
