PURPOSE: The purpose of this study was to assess the safety, tolerability, dosing, and efficacy of the active 19 amino acid fragment of lacritin (Lacripep), a broad regulator of ocular surface homeostasis, in the treatment of ocular surface disease associated with primary Sjögren syndrome.
METHODS: Two hundred four subjects were randomized to receive vehicle, 22 μM Lacripep, or 44 μM Lacripep 3 times daily for 28 days, preceded by a 14-day run-in and followed by 14-day washout. Outcome measures were corneal fluorescein staining (CFS), lissamine conjunctival staining, Schirmer with anesthesia, tear break-up time, SANDE scoring, and visual analog scale assessment of symptoms.
RESULTS: This study established the safety and tolerability of topical treatment with Lacripep in patients with primary Sjögren syndrome. There were few adverse events: Only mild irritation was found in less than 3 percent of patients dosed with Lacripep. Total CFS and Eye Dryness Score were not significantly changed at day 28. Post hoc analysis of patients with Eye Dryness Severity scores of 60 or greater at baseline revealed significant improvements in inferior CFS at 14 and 28 days and complaints of burning and stinging at 14 days. Significant improvement in regional lissamine conjunctival staining was seen at 14 and 28 days.
CONCLUSIONS: This first-in-human study of Lacripep in patients with primary Sjögren syndrome demonstrated clinically significant improvements in specific signs and symptoms on which to base future studies. This study established safety and tolerability and potential metrics of efficacy in patients with moderate to severe disease. Further work on appropriate dosing and concentration is ongoing.
