Sight Sciences, Pioneering the Development of the Standalone MIGS Market, Announces Publication of Favorable Two-Year Outcomes of Standalone Use of the OMNI® Surgical System in Mild to Moderate Open-Angle Glaucoma

Rhea-AI Summary

Sight Sciences (Nasdaq: SGHT) has announced favorable results from a study published in Clinical Ophthalmology, demonstrating the long-term safety and efficacy of the OMNI Surgical System in treating open-angle glaucoma. The 24-month study showed a significant reduction in intraocular pressure (IOP) from 24.6 mmHg to 14.7 mmHg, alongside a decrease in medication use. The results indicate that 100% of subjects achieved at least a 20% IOP reduction. Adverse events were consistent with expected outcomes in similar surgeries, underscoring the potential for OMNI's expanded applications.

Positive

• Statistically significant reduction in mean IOP from 24.6 mmHg preoperatively to 14.9 mmHg at 24 months.
• 100% of patients experienced at least a 20% reduction in IOP after 24 months.
• Decrease in mean IOP-lowering medication from 1.9 to 0.5 medications per patient at 24 months.
• Study supports long-term benefits of OMNI for standalone procedures in open-angle glaucoma.

Negative

• None.

Real-world data published in Clinical Ophthalmology show the safety, efficacy, and durability of effect of OMNI for use in a standalone procedure to reduce intraocular pressure and medication burden

MENLO PARK, Calif., Aug. 24, 2021 (GLOBE NEWSWIRE) -- Sight Sciences, Inc. (Nasdaq: SGHT), a growth-stage medical device company focused on developing and commercializing devices designed to address the underlying causes of the world's most prevalent eye diseases, today announced publication in Clinical Ophthalhmology of favorable 24-month outcomes from a single center open-label study of the OMNI® Surgical System conducted in Germany.

OMNI is cleared by the U.S. Food and Drug Administration (FDA) and CE-Marked for canaloplasty followed by trabeculotomy to reduce intraocular pressure (IOP) in adult patients with primary open-angle glaucoma (POAG) (FDA) and open-angle glaucoma (CE).* Sight Sciences intends to further develop OMNI, and to seek regulatory clearance, for expanded indications.

Results from the study, conducted and co-authored by Karsten Klabe, M.D. and Hakan Kaymak, M.D., report that use of OMNI to perform a standalone MIGS procedure (not combined with cataract surgery) in mild to moderate open-angle glaucoma resulted in statistically significant reductions in both IOP and IOP-lowering medication use at 24 months. The study included long-term (24-month) outcomes from 38 eyes of 27 subjects with open-angle glaucoma. First author, Dr. Klabe, directly performed canaloplasty followed by trabeculotomy on each patient using OMNI at his practice in Düsseldorf, Germany.

Mean baseline IOP in the study decreased from 24.6 mmHg preoperatively to 14.7 and 14.9 mmHg at months 12 and 24, respectively, reductions of approximately 10 mmHg or approximately 40%. All subjects in the study, and 100% of eyes, had at least a 20% IOP reduction at 24 months. Mean baseline IOP-lowering medication also decreased from 1.9 average medications per patient to 0.5 medications at month 24. At 24 months, nearly 60% of eyes were free of IOP-lowering medication. Both IOP and IOP-lowering medication reduction outcomes in the study were statistically significant (p<.0001). Importantly, the study cohort included primary open-angle glaucoma (71%) and pseudoexfoliation glaucoma (29%) patients, as well as phakic (74%) and pseudophakic (eye with an intraocular lens; 26%) eyes. Outcomes for these subgroups were observed to be similar to the overall results. Adverse events were observed to be consistent with those expected in angle or minimally invasive glaucoma surgery (MIGS). The most frequent was transient postoperative hyphema (17 eyes, 44%), in all cases 1 mm or less. Other adverse events included choroidal effusion (three eyes, 7.9%), anterior synechiae (two eyes, 5.3%), and transient lens-cornea touch associated with shallow anterior chamber (seen in one eye). All of these events were reported to have resolved spontaneously without intervention and with no sequelae. No secondary procedures were required to address adverse events.

“These results are particularly meaningful because they support the long-term benefits of OMNI for use in a standalone procedure, regardless of lens status, to reduce IOP and the burden of medication in adult patients with POAG,” said Paul Badawi, Co-Founder and CEO, Sight Sciences. “We believe that OMNI uniquely enables clinicians to perform two implant-free procedures to address all three points of resistance in the diseased conventional outflow pathway with a single device through a single clear corneal microincision. We believe that these results may support OMNI’s potential for expanded indications in other glaucoma patient populations.”

“By comprehensively addressing the entire conventional outflow pathway circumferentially with OMNI, clinicians can address outflow resistance wherever it occurs,” said Dr. Klabe. “OMNI offers clinicians a safe, effective and minimally invasive option for treating both phakic and pseudophakic patients outside of cataract surgery. I’m excited to see these outcomes further validate my clinical experience and success using OMNI on a standalone basis.”

About Sight Sciences
Founded in 2011, Sight Sciences develops and commercializes intelligently designed and engineered products that target the underlying causes of the world’s most prevalent eye diseases. The company currently markets two products, the OMNI^® Surgical System and the TearCare^® System. For more information, visit www.sightsciences.com.

About OMNI® Surgical System
The OMNI® Surgical System is a handheld, single use therapeutic device for minimally invasive glaucoma surgery (MIGS). OMNI allows surgeons to access 360 degrees and all three primary points of resistance of an eye’s diseased conventional outflow pathway (trabecular meshwork, Schlemm’s canal, and collector channels) through a single clear corneal microincision.

*OMNI is indicated by the FDA for canaloplasty (the microcatheterization and viscodilation of Schlemm’s canal) followed by trabeculotomy (the cutting of trabecular meshwork) to reduce intraocular pressure in adult patients with primary open-angle glaucoma. OMNI has a CE Mark for the catheterization and transluminal viscodilation of Schlemm's canal and the cutting of trabecular meshwork to reduce intraocular pressure in adult patients with open-angle glaucoma.

OMNI should not be used in any situations where the iridocorneal angle is compromised or has been damaged since it may not be possible to visualize the angle or to properly pass the microcatheter. Do not use OMNI in patients with angle recession; neovascular glaucoma; chronic angle closure; narrow-angle glaucoma; traumatic or malignant glaucoma; or narrow inlet canals with plateau iris or in quadrants with previous MIGS implants.
