Sjögren's dry eye study probes corneal nerve damage
NCT ID NCT06411132
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to find out how many people with Sjögren's dry eye have reduced feeling in their cornea (the clear front part of the eye). Researchers measured corneal sensitivity, tear production, and pain in 103 adults with confirmed Sjögren's syndrome and dry eye. The study was terminated early, so results may be limited.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
A total of 182 patients were planned to be included in the study. Due to its early termination, a total of 114 patients were screened and 103 patients were included in the FAS. Eleven patients did not meet the inclusion and/or exclusion criteria. All patients (103 patients) completed the study. The screened population consisted of all patients who signed the ICF and were assigned a patient identification number. The full analysis set (FAS) included all patients who met all the inclusion criteria and none of the exclusion criteria at the end of the screening procedure. All the analyses on the primary, secondary endpoints are provided on this population (FAS).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients ≥18 years of age at time of screening. 2. Confirmed diagnosis of Sjögren's for a minimum of 3 months before enrollment, as determined by either serologic antibody testing (anti-SSA/anti-SSB) or biopsy of minor salivary glands. 3. Confirmed diagnosis of dry eye for a minimum of 3 months before enrollment, as determined by signs and/or symptom assessment. 4. Fluorescein corneal staining with a cobalt blue light must show punctate corneal fluorescein staining or staining consistent with corneal epithelial damage equivalent or greater than 1 on the NEI scale by dry eye at enrollment. 5. Only patients who satisfy all informed consent requirements were included in the study. The patient and/or his/her legal representative should read, sign, and date the IRB-approved informed consent document before any study-related procedures were performed. 6. Patients should have the ability and willingness to comply with study procedures. Exclusion Criteria: 1. Inability to speak and understand English sufficiently to understand the nature of the study, to provide written informed consent, and to allow the completion of all study assessments. 2. Presence of active ocular infection (bacterial, viral, protozoal) in either eye, as deemed by the Investigator or confirmed culture. 3. Previous use of OXERVATE® ophthalmic solution. 4. Presence of gross epithelial defect, including a defect with stromal involvement. 5. Any concurrent medical condition that, in the judgment of the Investigator, might interfere with the conduct of the study or confound the interpretation of the study results. 6. Any eyelid abnormalities, such as lagophthalmos, entropion, ectropion, or other neuromuscular abnormalities, that result in prolonged exposure of the corneal surface. 7. Concurrent epithelial corneal disease or dystrophy unrelated to dry eye, such as anterior basement membrane dystrophy. 8. Inability to remove contact lenses for a minimum of 3 hours before corneal sensitivity testing. 9. Inability to discontinue use of all topical ophthalmic treatments for a minimum of 3 hours before corneal sensitivity testing. 10. Inability to suspend use of any neurostimulatory drugs or devices (including but not limited to nasal varenicline, iTear100, etc.) for treating dry eye or increasing tear film for 6 hours before testing. 11. Ocular surgery (including but not limited to laser-assisted in situ keratomileusis, photorefractive keratectomy, tube shunt/trabeculectomy, or cataract surgery) within the last 6 months. 12. History of corneal stromal surgery, including anterior lamellar keratoplasty, deep anterior lamellar keratoplasty, and penetrating keratoplasty. 13. Current participation in another clinical study that might affect corneal sensitivity or tear production.
