Harrow Announces 52-Week Data from VEVYE® ESSENCE-2 Open-Label Extension Study

Data Demonstrates Sustained Safety and Efficacy in Treating Signs and Symptoms of Dry Eye Disease

Harrow (Nasdaq: HROW), a leading North American eyecare pharmaceutical company, is pleased to announce results from its ESSENCE‑2 open-label extension (OLE) clinical study for VEVYE® (cyclosporine ophthalmic solution) 0.1%, the first and only cyclosporine to treat the signs and symptoms of dry eye disease (DED). ESSENCE-2 OLE was a Phase 3, prospective, multicenter, open-label, clinical study with 202 patients, who had previously completed the ESSENCE‑2 study, receiving VEVYE in each eye twice a day for 52 weeks. The one-year study results, published in Cornea, demonstrated VEVYE’s sustained safety and efficacy in treating the signs and symptoms of DED, underscoring its value in managing this chronic condition. Key findings include:

• Statistically significant improvements in all prespecified efficacy endpoints compared with baseline at each visit.
• Corneal staining improvements were early and stabilized over time while tear production improved continuously and symptomatology improvement followed these effects.
• The most common ocular treatment-related adverse events were mild instillation site pain in 13 patients (6.5%) and reduced visual acuity in 6 patients (3.0%). One patient withdrew during the 52-week study due to an ocular adverse event (mild burning/stinging).
• On a 0 to 10 scale (the higher the number equating to a better rating), when patients were asked to rate the question, “How satisfied are you with the study eye drop?”— 33.1% of patients provided the highest possible rating of 10. Approximately 91% of patients rated a score of 5 or higher, indicating satisfaction with the treatment.
• Investigators conclude that water-free cyclosporine 0.1% ophthalmic solution was safe and well tolerated during long-term use.

Dr. John D. Sheppard, Ophthalmologist, President of Virginia Eye Consultants, and one of the investigators on the ESSENCE‑2 OLE study, stated, “Topical cyclosporine has established a remarkable decades-long efficacy and safety profile. Finally, we have the right vehicle.”

Dr. Laura M. Periman, Ophthalmologist and Director of Dry Eye Services and Clinical Research at Periman Eye Institute, added, “We know that tolerability is a major issue with long-term immunomodulatory medications leading to poor patient compliance and dropout. In this 52-week study, perhaps the most impressive data point was that only one patient stopped using VEVYE because of an ocular adverse event, which was mild burning and stinging. Also, patients randomized to VEVYE in ESSENCE-2 that continued into the OLE, on average, saw their natural tear production nearly double after 56 weeks of treatment from baseline. Furthermore, these patients saw a statistically significant improvement in all measured symptoms at all measured time points compared to baseline. ESSENCE-2 OLE data demonstrates the long-term potential of VEVYE for patients suffering from chronic dry eye disease.”

Mark L. Baum, Chairman and Chief Executive Officer of Harrow, said, “The OLE data affirms why VEVYE is such a special product and why so many patients are now entering their sixth refill cycle. VEVYE’s unique value is enabled because of its patented water-free formulation, which catalyzes additional product features and related clinical benefits¹: VEVYE is preservative-free, has no pH or osmolarity, and requires only twice‑daily dosing with an individual dosage that is 1/10^th the size of conventional eye drops. In addition, in a pre-clinical ex-vivo corneal penetration study², VEVYE’s semi-fluorinated alkane vehicle, perfluorobutylpentane (PFBP), delivered approximately 22 times more cyclosporine into the cornea compared to RESTASIS®. This OLE data supports our efforts to make sure eyecare professionals and their patients are aware of how VEVYE helps manage dry eye disease by improving – over the longer term – the signs and symptoms of this chronic disease.”

About VEVYE® (cyclosporine ophthalmic solution) 0.1%

VEVYE (cyclosporine ophthalmic solution) 0.1%, non-preserved, for topical ophthalmic use. Approved by the U.S. Food and Drug Administration (FDA) in June 2023, VEVYE combines a semifluorinated alkane eyedrop technology (perfluorobutylpentane) with cyclosporine 0.1% in solution. VEVYE is indicated to treat both the signs and symptoms of DED. Clinical trials for VEVYE have demonstrated that it not only increases tear production, but it also has been shown to improve the cornea surface as evidenced by total corneal fluorescein staining (tCFS). Clinical trials also show that VEVYE’s clinical benefits begin as early as 15 days and show sustained improvement over 12 months – all while maintaining an excellent patient tolerability and low adverse event profile.

INDICATIONS AND USAGE

VEVYE is indicated for the treatment of the signs and symptoms of dry eye disease.

CONTRAINDICATIONS

None.

WARNINGS AND PRECAUTIONS

Potential for Eye Injury and Contamination. To avoid the potential for eye injury and/or contamination, patients should not touch the bottle tip to the eye or other surfaces.

Use with Contact Lenses. VEVYE should not be administered while wearing contact lenses. If contact lenses are worn, they should be removed prior to administration of the solution. Lenses may be reinserted 15 minutes following administration of VEVYE ophthalmic solution.

ADVERSE REACTIONS

Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials with 738 subjects receiving at least 1 dose of VEVYE, the most common adverse reactions were instillation site reactions (8%) and temporary decreases in visual acuity (3%).

USE IN SPECIAL POPULATIONS

Pregnancy. There are no adequate and well-controlled studies of VEVYE administration in pregnant women to inform a drug-associated risk.

Lactation. Caution should be exercised when VEVYE is administered to a nursing woman.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
