Effect of Acoltremon Ophthalmic Solution 0.003% on Tear Production and Symptoms in Patients With Tear Deficiency and Concurrent Neuropathic Corneal Pain (AURORA)
This study is designed to provide clinical data on how acoltremon ophthalmic solution 0.003% affects tear production and ocular symptoms in participants with tear deficiency and concurrent neuropathic corneal pain. Acoltremon is formulated to help increase natural tear production by activating TRPM8 (Transient Receptor Potential Melastatin 8) receptors on cold-sensitive corneal nerves. It is thought that this study treatment may help participants by increasing tear production while potentially reducing neuropathic ocular symptoms, including pain and discomfort.
Participants will be followed for 8 weeks, evaluating the mean change in unanesthetized Schirmer test score between 3 minutes post-drop at Week 8 compared to pre-drop at baseline (Day 1), change in neuropathic symptom intensity as measured by a 0-10 VAS (Visual Analog Scale) from baseline to Week 8, and change in quality of life as assessed by the Ocular Pain Assessment Survey (OPAS) from baseline to Week 8. The study will also evaluate changes in corneal nerve structure, nerve function, corneal sensitivity, ocular surface symptoms, and treatment satisfaction.

Description détaillée
AURORA is a prospective, open-label, single-center, single-arm investigator-initiated study evaluating TRYPTYR (acoltremon ophthalmic solution 0.003%) in 28 adults with neuropathic corneal pain and concurrent tear deficiency. Eligible participants must have neuropathic ocular symptoms for at least 3 months, a driving symptom score of at least 4 on a 0-10 VAS (Visual Analog Scale), reduced corneal nerve density and microneuromas on IVCM (In Vivo Confocal Microscopy), at least 50% symptom improvement following topical proparacaine, and an unanesthetized Schirmer score of at least 2 mm but less than 10 mm.
Participants will administer acoltremon 0.003% in both eyes twice daily for 8 weeks. One qualifying eye per participant will be designated as the study eye for analysis. There is no placebo or comparator group.
The primary endpoint is the mean change in unanesthetized Schirmer score from pre-drop baseline to 3 minutes post-drop at Week 8. Secondary endpoints include acute change in Schirmer score on Day 1, change in neuropathic ocular symptom intensity on the VAS (Visual Analog Scale), and change in quality of life measured by OPAS (Ocular Pain Assessment Survey). Exploratory outcomes include changes in corneal nerve structure and function, corneal sensitivity, OSDI (Ocular Surface Disease Index) scores, drop comfort, and treatment satisfaction.
Safety monitoring will focus on corneal staining, visual acuity, discomfort following drop administration, and adverse events, with a safety assessment conducted after the first five participants.
