Harrow Announces Commercial Launch of BYOOVIZ® in the United States

Expands Harrow's Growing Retina Portfolio with an Interchangeable Ranibizumab Biosimilar

NASHVILLE, Tenn., July 01, 2026 (GLOBE NEWSWIRE) -- Harrow (Nasdaq: HROW), a leading provider of ophthalmic disease management solutions in North America, today announced the commercial launch of BYOOVIZ® (ranibizumab-nuna), an FDA-approved biosimilar referencing LUCENTISⁱ (ranibizumab) and developed by Samsung Bioepis Co., Ltd.

The launch follows Harrow's exclusive U.S. commercialization agreement with Samsung Bioepis, one of the world's leading biosimilar developers and manufacturers. Through this partnership, Harrow obtained exclusive U.S. rights to commercialize BYOOVIZ and OPUVIZ® (aflibercept-yszy), an FDA-approved biosimilar referencing EYLEAⁱⁱ (aflibercept), further strengthening the Company's position in the rapidly growing retinal biologics market.

BYOOVIZ was approved by the U.S. Food and Drug Administration (FDA) as the first ophthalmology biosimilar in the U.S. for the treatment of patients with Neovascular (Wet) Age-Related Macular Degeneration (AMD), Macular Edema following Retinal Vein Occlusion (RVO), and Myopic Choroidal Neovascularization (mCNV). As an FDA-designated interchangeable biosimilar to LUCENTIS, BYOOVIZ provides retina specialists with a clinically proven anti-VEGF therapy that offers confidence, flexibility, and choice in patient care.

The launch of BYOOVIZ marks another important step in the evolution of Harrow's market-leading retina franchise. With an estimated $9 billion U.S. anti-VEGF marketⁱⁱⁱ and increasing demand for therapies that treat sight-threatening retinal diseases, Harrow continues to build a differentiated portfolio of buy-and-bill products designed specifically for the needs of retina specialists and the patients they serve.

BYOOVIZ joins Harrow's expanding retina franchise, which includes IHEEZO® (chloroprocaine hydrochloride 3% ophthalmic gel), a branded FDA-approved ocular anesthetic indicated for ocular surface anesthesia that is increasingly utilized by retina specialists during intravitreal injection procedures, and TRIESENCE® (triamcinolone acetonide injectable suspension) 40 mg/ml, a high-trust preservative-free injectable corticosteroid, broadly labeled and increasingly used by retina specialists nationwide. Together, these products enable Harrow to support both the procedural and therapeutic aspects of retinal disease management, providing retina practices with a trusted commercial partner across multiple points of care.

"BYOOVIZ is far more than a product launch—it underscores Harrow's commitment to the U.S. retina community," said Mark L. Baum, Founder, Chairman, and Chief Executive Officer of Harrow. "Over the past several years, we have earned the trust of physicians through products like IHEEZO and TRIESENCE—products a growing number of retina specialists have integrated into their procedural workflows—supported by one of the most experienced and tenured retina teams in the industry. The investments we’ve made in our commercial infrastructure are specifically designed to serve retina specialists, and we intend to keep investing in and growing our retina franchise for years to come. With BYOOVIZ, we will bring our customers an interchangeable ranibizumab biosimilar to a market increasingly focused on both clinical confidence and economic value. Together with exclusive commercialization rights to OPUVIZ in the US, we believe we are creating one of the most compelling retina portfolios in ophthalmology."

“The introduction of BYOOVIZ gives retina specialists another valuable treatment option for our patients,” said Samuel A. Minaker, M.D., vitreoretinal surgeon, Director of Clinical Research at Tyler Retina Consultants. “Many of my patients are treated with LUCENTIS or a LUCENTIS-referenced biosimilar; however, we have found that access to supply has not always been assured, with products coming in and out of availability more recently. What gives me additional confidence in BYOOVIZ is its interchangeability designation, supported by data showing no clinically meaningful differences between the biosimilar and reference product when patients switch between therapies. Just as importantly, it's exciting to see this product return to the market through a commercial partner like Harrow that has already earned credibility in my practice and within the retina community. Harrow understands the needs of retina practices, has demonstrated a commitment to supporting physicians and patients, and brings a level of confidence that makes BYOOVIZ a welcome addition to the treatment options available for my patients.”

“I’ve had the opportunity to work with Harrow on several ophthalmic products,” said Seenu M. Hariprasad, M.D., Chair of Ophthalmology and Visual Science, Chief of Vitreoretinal Service, and Shui-Chin Lee Professor of Ophthalmology and Visual Science at the University of Chicago Medicine. “I first worked with Harrow through IHEEZO, which helped improve the patient experience during intravitreal injection procedures, and later with TRIESENCE, an important treatment option for many patients. Throughout that time, their team has demonstrated an understanding of the clinical, operational, and economic realities retina specialists face every day. Adding BYOOVIZ to their portfolio is a natural extension of that experience. Having access to a trusted ranibizumab biosimilar from a company with experience supporting retina specialists makes BYOOVIZ a welcome addition to the treatment options available for patients.”
