ALPHARETTA, Ga., May 08, 2019 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a biopharmaceutical company dedicated to developing treatments that restore and preserve vision for people with serious eye diseases, today reported financial results for the first quarter of 2019 and provided a corporate update.

“Clearside has a compelling opportunity to leverage our innovative, non-surgical  suprachoroidal space (SCS) delivery platform to make a difference for patients with sight-threatening diseases in the U.S. and around the world,” said George Lasezkay, Pharm.D., J.D., Clearside’s Interim Chief Executive Officer. “We believe our proprietary approach and strong intellectual property in the suprachoroidal space are broadly applicable across a range of serious ophthalmic diseases.”

Dr. Lasezkay continued, “We are validating our platform with the potential approval of our first product candidate, XIPERE™ (triamcinolone acetonide ophthalmic suspension) for Suprachoroidal Injection for the treatment of macular edema associated with uveitis, a condition that currently has no approved therapies. Uveitis is a leading cause of vision impairment and blindness in the developed world, and treating the associated macular edema is particularly important as it is an underserved patient population often affecting younger people and can result in numerous years of lost visual function.”

“We have a highly experienced team that developed XIPERE, submitted our New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA), and is now focused on achieving the successful approval and launch of our first commercial product. We are also committed to maximizing our SCS injection platform to expand our product pipeline and create future value through select strategic partnerships. As indicated in recent medical meeting presentations, the potential of our SCS injection platform includes small molecule therapeutics and may extend to gene-based therapies for inherited retinal diseases,” concluded Dr. Lasezkay.

Key Highlights

• Clearside’s NDA for XIPERE for the treatment of macular edema associated with uveitis was accepted for review by the FDA and assigned a PDUFA (Prescription Drug User Fee Act) goal date of October 19, 2019.
• Biopharmaceutical executive and current Clearside Board member, George Lasezkay, Pharm.D., J.D., was appointed to the position of Interim Chief Executive Officer.
• Use of Clearside’s SCS injection platform in uveitis patients and with gene therapy was highlighted at the Association for Research in Vision and Ophthalmology (ARVO) 2019 Conference.
• Clearside’s SCS injection platform was featured at the 42nd Annual Meeting of The Macula Society in multiple oral presentations, including release of new, non-clinical data on suprachoroidal administration of gene-based therapies.

First Quarter 2019 Financial Results

Clearside’s research and development expenses for the quarter ended March 31, 2019 were $11.0 million, compared to $13.4 million for the quarter ended March 31, 2018. The $2.4 million decrease was primarily related to lower clinical development costs for XIPERE.  

General and administrative expenses were $4.4 million for the quarter ended March 31, 2019, compared to $3.1 million for the quarter ended March 31, 2018. The $1.3 million increase was mostly attributable to increased employee-related costs and expenses related to the potential commercialization of XIPERE.

Net loss for the quarter ended March 31, 2019 was $15.4 million, or $0.45 per share of common stock, compared to $16.6 million for the quarter ended March 31, 2018, or $0.62 per share of common stock. The decrease in net loss was primarily related to lower clinical development costs.

Cash, cash equivalents and short-term investments totaled $34.9 million as of March 31, 2019, which includes $6.6 million in net proceeds from sales of common stock under the company’s at-the-market facility during the quarter.

About Clearside’s SCS Injection Platform

Clearside’s proprietary suprachoroidal space (SCS) injection treatment approach offers unprecedented access to the back of the eye where sight-threatening disease often occurs. The company’s unique platform is inherently flexible and intended to work with established medications, new formulations of medicines, as well as future innovations such as gene therapy.

About XIPERE

XIPERE™ (triamcinolone acetonide ophthalmic suspension) for Suprachoroidal Injection, formerly known as CLS-TA, is a proprietary suspension of the corticosteroid triamcinolone acetonide formulated for administration to the back of the eye via suprachoroidal injection for the treatment of macular edema associated with uveitis. Clearside’s patented technology is designed to non-surgically deliver drug to the suprachoroidal space located between the choroid and the outer protective layer of the eye, known as the sclera. Suprachoroidal injection enables the rapid and adequate dispersion of medicine to the back of the eye, offering the potential for the medicine to act longer and to minimize side effects and harm to the surrounding healthy parts of the eye, thus potentially providing advantageous and sustained efficacy with a favorable safety profile. An NDA was submitted to the FDA in December 2018 for XIPERE, and, if approved, XIPERE will be the first therapy indicated for macular edema associated with uveitis.
