MENLO PARK, Calif., April 10, 2024 (GLOBE NEWSWIRE) -- Sight Sciences, Inc. (Nasdaq: SGHT) (“Sight Sciences” or the “Company”), an eyecare technology company focused on developing and commercializing innovative, interventional technologies intended to transform care and improve patients’ lives, today announced the results as published in the American Journal of Ophthalmology (“AJO”) International of the large scale, comparative real-world clinical outcomes study of patients treated by three leading, minimally invasive glaucoma surgery (“MIGS”) technologies.
Using the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight), the largest specialty society clinical data registry in all of medicine and the first comprehensive eye disease clinical registry in the United States, this large-scale MIGS study evaluated long-term 2-year post-surgical outcomes among patients with primary open-angle glaucoma (“POAG”) treated with the three most commonly used FDA-approved/cleared ab interno MIGS devices in the U.S. (OMNI Surgical System (“OMNI”), Hydrus® Microstent, and iStent inject®) combined with cataract surgery, as well as for cataract surgery alone.
OMNI facilitates a unique implant-free, ab interno procedure that comprehensively addresses the three primary areas of resistance in the conventional outflow pathway. OMNI technology has been cleared by the FDA for canaloplasty followed by trabeculotomy to reduce intraocular pressure in adult patients with primary open-angle glaucoma.
Baseline Patient Characteristics:
- The entire study cohort consisted of 77,391 patients with glaucoma and 109,745 glaucomatous eyes
- 6,632 patients and 9,000 eyes received a MIGS procedure in combination with cataract surgery, and the remainder received cataract surgery alone
- The four cohorts had generally similar baseline characteristics in terms of intraocular pressure (“IOP”) and mean number of IOP-lowering medications (see table below)
- The overall population was divided into two subgroups depending on the baseline, pre-surgical lOP; > 18 mmHg and ≤ 18 mmHg. The primary treatment goal for the high baseline IOP group (> 18mmHg) was IOP reduction, with a secondary goal to reduce medication burden. The primary treatment goal for the low baseline IOP group (< 18mmHg) was to reduce medication burden.
| Baseline | Group 1 Pre-op (> 18mmHg IOP) | Group 2 Pre-op (≤ 18mmHg IOP) | ||
| Mean IOP (mmHg) | Number of IOP-Lowering Medication Classes | Mean IOP (mmHg) | Number of IOP-Lowering Medication Classes | |
| OMNI Surgical System | 22.5 | 1.95 | 14.1 | 2.01 |
| Hydrus Microstent | 22.5 | 1.89 | 14.2 | 1.89 |
| iStent inject | 22.2 | 1.58 | 14.4 | 1.58 |
| Cataract-Surgery Alone | 22.8 | 1.60 | 14.5 | 1.62 |
Clinical Outcomes:
- At 24 months, high baseline IOP (>18 mmHg) patients who received the outflow procedure using OMNI technology had:
- the greatest numerical reduction in IOP, and
- the greatest numerical reduction in medication use
- At 24 months, low baseline IOP (≤18 mmHg) patients who received the outflow procedure using OMNI technology had:
- the greatest numerical reduction in IOP, and
- a statistically significantly greater mean medication use reduction compared to all other treatment groups
| Post Treatment @ 24 Months | Group 1 > 18mmHg IOP Treatment Goal: IOP and Medication Reduction | Group 2 ≤ 18mmHg IOP Treatment Goal: Medication Reduction | ||
| Mean Reduction in IOP mmHg (% Change From Baseline) | Mean Medication Class Reduction | Mean Reduction in IOP mmHg (% Change From Baseline) | Mean Medication Class Reduction | |
| OMNI Surgical System | -6.64 (30%) | -1.34 | -0.47 (3%) | -1.42 |
| Hydrus Microstent | -5.71 (25%) | -1.20 | +0.03 (0%) | -1.18 |
| iStent inject | -4.96 (22%) | -0.86 | -0.17 (1%) | -0.95 |
| Cataract-Surgery Alone | -5.55 (24%) | -0.67 | -0.07 (0%) | -0.65 |
“Consistent with our many prior published studies, this large-scale, real-world MIGS dataset from the IRIS Registry, as analyzed by Verana Health® and published in a top peer-reviewed journal, corroborates that the OMNI procedure is efficacious as it delivers clinically meaningful and durable reductions in both intraocular pressure and medication use at two years. OMNI technology was designed with the goal of restoring the natural outflow process of the eye by addressing the three areas of resistance associated with primary open-angle glaucoma. We are excited to see that large-scale comparison studies of MIGS standards-of-care continue to corroborate the robust IOP reduction and medication reduction associated with the comprehensive OMNI outflow procedure,” said Paul Badawi, co-founder and CEO of Sight Sciences. “I’d also like to thank the team at Verana Health and the American Academy of Ophthalmology for making critical, real-world, large-scale, clinical outcome information in the IRIS Registry available for all stakeholders, including eyecare providers, payors, industry, and researchers.”
