Safety and Efficacy Study on Cenegermin (Oxervate®) vs Vehicle in Severe Sjogren's Dry Eye Disease (PROTEGO-1 Study)

Completed · Phase 3

Conditions studied: Dry Eye

In brief

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.
