Sight Sciences Announces Positive Results and Primary Endpoint Successfully Met in SAHARA, a Randomized Controlled Clinical Trial Comparing Interventional Eyelid Procedures Enabled by TearCare Technology to Restasis¹ for the Treatment of Dry Eye

Dry eye has significant negative impact on visual function including reading, driving, workplace productivity, physical functioning, and quality of life, and creates a substantial burden to patients and society in general²

MENLO PARK, Calif., July 20, 2023 (GLOBE NEWSWIRE) -- Sight Sciences, Inc. (Nasdaq: SGHT) (“Sight Sciences,” or the “Company”), an eyecare technology company focused on developing and commercializing innovative technology intended to transform care and improve patients’ lives, today announced the six-month results from the SAHARA randomized controlled trial (RCT). The trial successfully met its primary endpoint and the data reported statistically significant improvements as compared to Restasis eye drops for the treatment of dry eye disease. These results will be presented in greater detail at the American Academy of Optometry’s annual meeting in October 2023.

SAHARA Phase I Results:

• The SAHARA trial achieved its primary six-month endpoint, demonstrating the superiority of interventional eyelid procedures enabled by TearCare over Restasis eyedrops in the improvement of tear break up time (TBUT), a key measure of aqueous retention, tear stability and the tear film’s ability to protect the ocular surface.
• The SAHARA trial also observed that procedures enabled by TearCare were non-inferior to Restasis eyedrops in Ocular Surface Disease Index (OSDI), which was the co-primary six-month endpoint.
• Throughout the study, interventional eyelid procedures with TearCare demonstrated clinically and statistically significant improvements of every endpoint and at every measurement interval: one week, one month, three months, and six months. Endpoints assessed include TBUT, meibomian gland score, corneal staining, and conjunctival staining. Symptoms endpoints include two commonly used patient-reported questionnaires: Ocular Surface Disease Index (OSDI) and Symptom Assessment in Dry Eye (SANDE).
  

“At each measurement interval over the initial six-month study period, subjects in the TearCare cohort exhibited statistically significant improvement in all key signs and symptoms,” remarked Brandon Ayres, MD, FAAO, Co-Director Cornea Fellowship Program, Wills Eye Hospital and a Principal Investigator of Sahara. “As we hypothesized, the data from the SAHARA trial suggests that interventional eyelid procedures enabled by TearCare technology help directly address the root cause of MGD and were more effective than topical Restasis eyedrops in treating dry eye on an aggregate basis across the endpoints measured in the SAHARA trial. TearCare patients in the SAHARA trial benefitted from improved function of obstructed and diseased meibomian glands and experienced rapid improvement in dry eye symptoms. The results from SAHARA support and build on the results from prior TearCare technology trials. This landmark “device vs. drug” trial shows we should change how we treat meibomian gland disease and dry eye in the future.”
