DEFENDO Long Term Follow-up Study in Stage 1 NK Patients

Recruiting
Conditions
Neurotrophic Keratitis
Interventions
Drug: Cenegemin in the DEFENDO Study
Registration Number
NCT05552261
Lead Sponsor
Dompé Farmaceutici S.p.A
Brief Summary

The primary objectives are to evaluate the long-term safety and efficacy of OXERVATE™ 0.002% (20 mcg/mL) cenegermin-bkbj ophthalmic solution in Stage 1 Neurotrophic Keratitis (NK) patients who enrolled in the DEFENDO Study.

Detailed Description

This clinical study will be a multi-center, open label, long term follow-up study of the patients who were enrolled in the DEFENDO Study who had Stage 1 Neurotrophic Keratitis (NK) who were treated with OXERVATE™ 0.002% (20 mcg/mL) cenegermin-bkbj ophthalmic solution.

The DEFENDO Long-Term Follow-up Study will have follow-up with the patients at month 24-30 post-treatment in the DEFENDO Study: All patients will be evaluated in a real-world setting post the enrollment in the DEFENDO Study through 30 months. Patients will be treated per standard of care as determined by the Investigator and will document topical ophthalmic medications.

The original DEFENDO Study duration was for a total of 34 weeks: a screening period of 2 weeks, followed by enrollment in 8 weeks of OXERVATE™ treatment and an Off- Treatment Follow-Up of 6 months.

After completing enrollment in the original DEFENDO Study, patients will be invited to enter the DEFENDO Long- Term Follow-up Study (all standard of care is permitted).

Two additional long-term follow-up visits will occur at 24- and 30-months to evaluate long-term clinical outcomes.
