<div id="readability-page-1"><div>, /PRNewswire/ -- Innovent Biologics, Inc. (&#34;Innovent&#34;) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of oncology, cardiovascular and metabolic, autoimmune, ophthalmology and other major diseases, announces the completion of first patient dosing in the Phase 2 clinical study of efdamrofusp alfa (R&amp;D code: IBI302), a recombinant human vascular endothelial growth factor receptor (VEGFR)-antibody human complement receptor 1 (CR1) fusion protein, for the treatment of diabetic macular edema (DME).This randomized, double-masked, multi-center, active-controlled Phase 2 clinical study (NCT06908876) aims to evaluate the efficacy and safety of intravitreal injections of efdamrofusp alfa in DME patients. A total of 150 participants will be enrolled and randomized in a 1:1:1 ratio to the IBI302 4 mg group, the IBI302 8 mg group, and the Faricimab (anti-VEGF/ANG-2 bispecific antibody) 6 mg group. The primary endpoint is the change in best corrected visual acuity (BCVA) from baseline in the study eye at week 16.DME has become the leading cause of vision impairment among the diabetic population in China: According to statistics, China has over 140 million diabetic patients, with approximately one-third of them developing diabetic retinopathy (DR). Among patients with DR, the prevalence rate of DME ranges from 7% to 14%, indicating an estimated 4 to 5 million DME patients in China1.DME development is primarily driven by microvascular damage mediated by VEGF upregulation and inflammatory factors2. Complement activation is also involved in the development of DME by damaging the neurovascular units through cytolysis, opsonization, and promotion of proinflammatory microenvironment, leading to retinal microvascular lesions, neurodegeneration, and macular edema3. At present, intravitreal injections of anti-VEGF agents or glucocorticoids are key treatment strategies, effectively improving visual acuity and retinal edema. However, frequent intravitreal injections (every 4 to 8 weeks) can result in poor patient compliance and increased risk of complications such as cataract and elevated intraocular pressure, making it challenging to achieve sustained visual acuity benefits with long-term treatment4,5.In recent years, bispecific antibodies represented by Faricimab have demonstrated significant efficacy and extended dosing intervals in patients with DME; Faricimab currently represents the highest global treatment standard for DME.Efdamrofusp alfa, the first-in-class bispecific fusion protein targeting VEGF and complement, can simultaneously inhibit angiogenesis and vascular leakage mediated by VEGF, and inflammatory responses mediated by complement activation. To date, multiple clinical studies of efdamrofusp alfa have been conducted in patients with neovascular age-related macular degeneration (nAMD) and DME, among which high-dose (8 mg) efdamrofusp alfa has shown significant efficacy in improving visual acuity and retinal edema. Meanwhile, efdamrofusp alfa has demonstrated the potential for extended dosing intervals (up to 12-16 weeks), with favorable safety and tolerability.Professor Xiaodong Sun, the leading Principal Investigator of this Study, Deputy Director of Shanghai General Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, and Director of the Ophthalmology Center, stated, &#34; DME is one of the most common ocular fundus diseases in China, affecting up to 4- to 5 million patients. With increasingly the aging of the population and the continuous rise in diabetes prevalence in China, DME has become one of the diseases that seriously endangers public health, imposing heavy burdens to the society and individuals. Anti-VEGF drugs are currently the first-line treatment for DME, but huge unmet medical needs remain, such as frequent injections, long-term efficacy attenuation, and suboptimal response in a subset of patients . As a global first-in-class anti-VEGF-complement bispecific drug, efdamrofusp alfa has shown favorable safety profile, substantial improvement in visual acuity and macular edema, and the potential of extended dosing interval in the completed Phase 1 clinical study in DME patients, which has brought great confidence to our investigator team. efdamrofusp alfa. We look forward to the success of this Phase 2 study, hoping to provide of a new treatment option for a large number of DME patients.&#34;Dr. Lei Qian, Senior Vice President of Clinical Development of Innovent, stated, &#34;Efdamrofusp alfa is an anti-VEGF-complement bispecific fusion protein self-developed by Innovent with global proprietary rights. This clinical study will be globally the first study comparing two dual-target agents, using Faricimab, the global standard of care in DME. We look forward to the success of this study, which could provide support for a Phase 3 clinical trial and a new treatment option for patients. Innovent's general biomedicine pipeline covers cardiovascular, endocrine and metabolic, ophthalmology, and autoimmune disease areas. We will continue to develop new therapies, providing physicians with more clinical treatment options and benefiting more patients.&#34;About diabetic macular edemaDiabetic retinopathy (DR) is a series of lesions caused by retinal microvascular damage resulting from diabetes and is the main microvascular complication of diabetes. Diabetic macular edema (DME), featuring retinal edema, thickening and exudation, is caused by capillary leakage in the macular area. It is the result of the blood-retinal barrier (BRB) destruction and mainly affects central vision. At present, DR has become the leading cause of blindness among the working-age population worldwide, while DME has become the main cause of visual impairment among the diabetic population6.The pathological mechanisms of DR and DME are multifactorial, involving metabolic abnormalities related to hyperglycemia, oxidative stress, and inflammation. These processes lead to the upregulation of vasoactive factors such as VEGF, which subsequently disrupt the BRB and increase vascular permeability, manifesting clinically as retinal edema and exudation. When the macular area is involved, it develops into DME2. Additionally, complement system activation contributes to disease progression by damaging the neurovascular units through cytolysis, opsonization, and promotion of proinflammatory microenvironment, causing retinal microvascular lesions, neurodegeneration, macular edema, and retinal neovascularization3.About Effamrofusp Alfa (IBI302)Efdamrofusp alfa is a recombinant, fully human bispecific fusion protein developed by Innovent Biologics with global intellectual property rights. The N-terminal is the VEGF-binding domain, which can bind to the VEGF family to block the VEGF-mediated signaling pathway, inhibiting the survival and proliferation of vascular endothelial cells, thereby inhibiting angiogenesis, reducing vascular permeability, and reducing vascular leakage. The C-terminal is the complement binding domain, which can inhibit complement activation through the classical pathway and the bypass pathway by specifically binding to C3b and C4b, and thereby alleviate the inflammatory response mediated by complement activation. Through this dual mechanism, efdamrofusp alfa exerts its therapeutic effects by inhibiting both VEGF-mediated angiogenesis and complement activation pathways.About InnoventInnovent is a leading biopharmaceutical company founded in 2011 with the mission to empower patients worldwide with affordable, high-quality biopharmaceuticals.
