Neurotrophic Keratitis

Objective: To evaluate the safety of Lacripep 4 μM Ophthalmic Solution and its effect on the ocular surface, visual function, corneal sensitivity, and quality of life of subjects with Stage 1 NK.

This is a Phase II, double-blind, placebo-controlled study to evaluate the safety and efficacy of STSP-0902 ophthalmic solution in patients with neurotrophic keratitis (NK). The study plans to enroll 48 patients with Mackie Stage 2 or 3 NK affecting one or both eyes. Eligible subjects will be randomized 1:1:1 into three dosing groups. Each dosing group will follow a drug-placebo allocation (12 active: 4 placebo). Treatment involves topical ocular administration for 8 weeks. Subjects who are not healed after the 8 weeks of masked treatment period will be permitted to receive standard of care during the follow-up period

The Sponsor is developing KB801, a replication-defective, non-integrating herpes simplex virus type 1 (HSV-1)-derived vector engineered to deliver functional full-length human nerve growth factor (NGF) to the corneas of people with Stage 2 or 3 neurotrophic keratitis (NK) via topical application. This is a Phase 1/2, multicenter, double-masked, placebo-controlled study to evaluate the safety, tolerability, and preliminary efficacy of KB801 in these subjects.

This pilot study evaluates the feasibility and outcomes of two treatment approaches for corneal sensory dysfunction due to neurotrophic keratitis (NK): corneal neurotization surgery and topical Cenergermin (Oxervate). Participants will receive treatment based on clinical decision-making, not randomization, and will be followed for 12 months through eight visits at the Ivey Eye Institute, St. Joseph's Health Care London. Data collected during routine eye examinations and validated quality-of-life questionnaires will be used to assess visual outcomes, corneal structure and function, and patient-reported well-being. This feasibility study is funded by the Lawson Research Institute Internal Research Fund and is intended to generate preliminary evidence for a future randomized trial.

Single-site, open label pilot study of 20 autoimmune patients diagnosed with dry eye demonstrating via the proparacaine challenge some peripheral corneal pain component. At least 16 patients will receive and complete 12 weeks of 80 units of Acthar Gel to be injected subcutaneously twice weekly via Acthar Gel single-dose pre-filled SelfJectTM injector (SelfJect) to assess the effects on subjective sensation of ocular pain, conjunctival and corneal staining, in vivo assessments of corneal nerves as measured by confocal imaging, VAS scales of common neuropathic pain symptoms and comfort of SelfJect will be assessed.

The objective of this study is to obtain initial efficacy of BRM424 in patients with Stage 2 and Stage 3 NK and evaluate safety and tolerability.
