WATERTOWN, Mass., November 6, 2018 (GLOBE NEWSWIRE) — EyePoint Pharmaceuticals, Inc. (NASDAQ: EYPT), a specialty biopharmaceutical company committed to developing and commercializing innovative ophthalmic products, today reported operating and financial results for its fiscal 2019 first quarter ended September 30, 2018 and highlighted recent clinical and operational developments.

“The approval of YUTIQ™ by the U.S. FDA in October marked a significant achievement for EyePoint and validates the Company’s innovation and ability to develop an effective treatment to decrease recurrence of uveitic flares from non-infectious posterior segment uveitis that can result in blindness,” said Nancy Lurker, President and Chief Executive Officer of EyePoint Pharmaceuticals. “Following the positive reception by retina and uveitis specialists of the clinical data presented for YUTIQ at the American Academy of Ophthalmology 2018 Annual Meeting, we believe that we are well-positioned for a successful product launch planned in the first quarter of calendar 2019. In addition, we are scaling up our manufacturing of DEXYCU™ ahead of an anticipated launch in the first half of calendar 2019.”

Recent Clinical & Operational Highlights

Fiscal First Quarter 2019 Results

Revenue for the three months ended September 30, 2018 totaled $486,000 compared to $385,000 for the prior year quarter. Revenues in both periods were primarily derived from royalty income under existing collaboration agreements.

Operating expenses for the quarter ended September 30, 2018 increased to $14.0 million from $6.4 million a year earlier, due primarily to initial investments in sales and marketing infrastructure and program costs, amortization of the DEXYCU intangible asset, professional services and stock-based compensation. Non-operating expense, net in the quarter ended September 30, 2018 totaled $19.6 million and consisted primarily of a non-cash change in fair value of derivative liability and interest expense on our term loan. Net loss for the quarter ended September 30, 2018 was $33.1 million, or $0.44 per share, compared to a net loss of $6.0 million, or $0.15 per share, for the prior year quarter.

Cash and cash equivalents at September 30, 2018 totaled $55.8 million compared to $38.8 million at June 30, 2018. The cash balance of September 30, 2018 reflects proceeds of $28.9 million from the exercise of warrants in the quarter.
