HONG KONG, 2 January 2025 – Zhaoke Ophthalmology Limited (“Zhaoke Ophthalmology” or the “Company”, SEHK: 6622), a leading ophthalmic pharmaceutical company dedicated to the research and development, manufacture and commercialization of therapies that address significant unmet medical needs, is pleased to announce the positive top-line results from the Phase III clinical trial of one of the Company’s core products, TAB014, for the treatment of wet (neovascular) age-related macular degeneration (“wAMD”). The clinical trial successfully met its primary endpoints and key secondary endpoints.

The Phase III clinical trial of TAB014 is a randomized, double-blind and non-inferiority study. The main objective of the study is to evaluate the change from baseline in best corrected visual acuity (BCVA) at week 52 in the TAB014-treated subjects group compared with Lucentis®-treated subjects group. The study involved approximately 57 centres and enrolled a total of 488 patients, led by Professor Chen Youxin from Peking Union Medical College Hospital as the Principal Investigator.

Dr. Li Xiaoyi (Benjamin), Chairman of the Board, Executive Director and CEO of Zhaoke Ophthalmology, said, “The positive topline results from the Phase III trial of TAB014 are highly significant for Zhaoke. This achievement not only signals the advancement of another innovative drug into late-stage development, but also marks the beginning of another strategic focus for Zhaoke in the field of back-of-the-eye diseases. TAB014 is positioned as a cost-effective treatment for wAMD, a leading global cause of vision loss and blindness. At Zhaoke, we remain dedicated to addressing critical unmet medical needs and enhancing visual health both in China and internationally.”

About TAB014

TAB014 (recombinant humanized anti-vascular endothelial growth factor (“VEGF”) monoclonal antibody) is an ophthalmic formulation of bevacizumab being developed for the treatment of wAMD. The main pathological feature of wAMD is choroidal angiogenesis in the macula, with VEGF playing an important role in the angiogenesis process. TAB014 is able to bind specifically to VEGF and block it from binding to its receptors, thereby inhibiting angiogenesis. TAB014 will eventually be administered as an intravitreal injection for the treatment of wAMD.

About wAMD

wAMD is a leading cause of vision loss and blindness in people over 50 years old in China and globally. According to China Insights Consultancy the market size of wAMD drugs in China is forecast to increase from US$241.5 million to approximately US$3.5 billion from 2019 to 2030, at a CAGR of 27.5%. TAB014 is the first bevacizumab-based antibody under clinical development indicated for wAMD in China, and is expected to be a cost-effective therapy. The clinical research and commercialization project in relation to TAB014 was listed by the Development Center for Medical Science & Technology of the National Health Commission of China as a special major project for technologies of innovative manufacturing of major new drugs at the end of 2019.
