EYEN Eyenovia Inc

Eyenovia, Inc. (NASDAQ: EYEN), a clinical stage ophthalmic biopharmaceutical company developing a pipeline of microdose therapeutics utilizing its patented piezo-print delivery technology, today confirmed a broad patient population for its Phase III MicroProst program (microdose latanoprost with Optejet™ delivery) for the lowering of intraocular pressure (IOP). Following discussions with the U.S. Food and Drug Administration (FDA), the study population will include chronic angle closure glaucoma (CACG), as well as open angle glaucoma (OAG) and ocular hypertension (OHT) patients, representing a total addressable population of approximately 4 million in the United States. As anticipated, the Phase III program will be optimized to consist of a single MicroProst Phase III trial and supplemented with existing data on latanoprost for IOP lowering.

"We believe that our MicroProst study will include one of the broadest patient populations in glaucoma drug development to date. If approved, MicroProst could have one of the widest indications of commercially available IOP-lowering therapies, as well as represent the first FDA-approved drug specifically indicated for chronic angle closure glaucoma," commented Dr. Sean Ianchulev, Eyenovia’s Chief Executive Officer and Chief Medical Officer. "Based on the results of our earlier Phase II trial for IOP lowering, we believe that MicroProst may achieve similar clinical efficacy with improved tolerability versus latanoprost administered in drop form, which can overdose the eye with potentially harmful preservatives and active ingredient."

“Together, open angle glaucoma and ocular hypertension represent a larger patient population in the United States compared to chronic angle closure glaucoma. Having an FDA-approved drug with all three conditions specified in the label means that patients who are currently prescribed or are candidates for prostaglandin therapy may have the option for next-generation, smart, micro-dose delivery,” said Shan Lin, M.D., Glaucoma Specialist at the Glaucoma Center of San Francisco. “MicroProst may open up possibilities for patients who cannot use current eyedropper treatments due to intolerance to high-volume drug and preservative, inability to correctly instill eye drops, or poor compliance.”

About EyenoviaEyenovia, Inc. (NASDAQ: EYEN) is a clinical stage ophthalmic biopharmaceutical company developing a pipeline of microdose therapeutics utilizing its patented piezo-print delivery technology.

About MicroPine for Progressive MyopiaMicroPine is Eyenovia's first-in-class topical treatment for progressive myopia, a back-of-the-eye disease. Progressive myopia is estimated to affect close to 5 million patients in the United States who suffer from uncontrolled axial elongation of the sclera leading to increasing levels of myopia and in some cases major pathologic changes such as retinal atrophy, macular staphylomas, retinal detachment and visual impairment. Early dose finding studies by collaborative academic groups have demonstrated high therapeutic potential with low dose atropine which can reduce myopia progression by 60–70% with a sustained effect through three years. A recent therapeutic evidence assessment and review by the American Academy of Ophthalmology indicates Level 1 (highest) evidence of efficacy for the role of low dose atropine for progressive myopia (Ophthalmology 2017;124:1857-1866; Ophthalmology 2016; 123(2) 391:399).

About MicroStat for MydriasisMicroStat is Eyenovia's first-in-class fixed-combination micro-formulation product (phenylephrine-tropicamide) candidate for pharmacologic mydriasis (eye dilation), which is targeted to address the growing needs of the estimated 80 million office-based comprehensive and diabetic eye exams performed every year in the United States, as well as the estimated 4 million pharmacologic mydriasis applications for cataract surgery. We are developing MicroStat to help improve efficacy, usability and tolerability of pharmacologic mydriasis.

About MicroTears OTC for Dry EyeMicroTears is a micro-droplet ocular surface tear replenishment product candidate for the estimated $2 billion+ (200 million units) global annual OTC artificial tear market.

Upcoming Milestone: OTC Registration H1 2019

About OpteJet and MicroRx Ocular TherapeuticsEyenovia's OpteJet microdose formulation and delivery platform for ocular therapeutics uses high-precision piezo-print technology to deliver 6 – 8 μL of drug, consistent with the capacity of the tear film of the eye. We believe the volume of ophthalmic solution administered with the OpteJet is less than 75% of that delivered using conventional eyedroppers, thus reducing overdosing and exposure to drug and preservatives. Eyenovia's patented microfluidic ejection technology is designed for gentle ocular surface delivery in less than 80 milliseconds, beating the ocular blink reflex. The OpteJet's targeted delivery system has demonstrated 85% topical delivery efficacy compared to 40-50% with the conventional eyedropper, and its smart electronics and mobile e-health technology are designed to track and enhance patient compliance.
