PURPOSE:

To evaluate efficacy and safety of efdamrofusp alfa compared with aflibercept in neovascular age-related macular degeneration (nAMD).

DESIGN:

Randomized, double-masked, multicenter, active-controlled, noninferiority phase II study.

PARTICIPANTS:

A total of 231 treatment-naive and previously treated participants with active choroidal neovascularization secondary to nAMD were enrolled.

METHODS:

Eligible participants were randomized (1:1:1) to 2 mg efdamrofusp alfa, 4 mg efdamrofusp alfa, or 2 mg aflibercept groups. Participants in all groups received 3 initial monthly loading doses, followed by treatment every 8 weeks, with assessment every 4 weeks up to week 52.

MAIN OUTCOME MEASURES:

The primary end point was the mean best-corrected visual acuity (BCVA) change from baseline to week 36. The prespecified noninferiority margin was set as -5 letters (80% confidence interval [CI]).

RESULTS:

Each treatment group included 77 participants. The mean BCVA changes from baseline to week 36 for 2 mg efdamrofusp alfa, 4 mg efdamrofusp alfa and aflibercept groups were +10.6, +11.4, and +12.0 letters, respectively; least squares mean difference were -1.4 (80% CI: -3.5 to 0.7) between 2 mg efdamrofusp alfa and aflibercept, and -0.6 (80% CI: -2.7 to 1.6) between 4 mg efdamrofusp alfa and aflibercept. Mean central retinal thickness changes were consistent across groups. Adverse event rate was comparable among the groups.

CONCLUSIONS:

Efdamrofusp alfa demonstrated noninferiority to aflibercept in BCVA improvement, accompanied by a similar safety profile.

Article

Author: Li, Tong ; Gong, Yuanyuan ; Lu, Shujie ; Wang, Fenghua ; Jia, Huixun ; Liu, Haiyun ; Feng, Liqi ; Qian, Lei ; Sun, Xiaodong ; Liu, Wenjia ; Wan, Qiuchen ; Chen, Jieqiong ; Wang, Hong ; Sun, Junran ; Liu, Xiaoling

PURPOSE:

To evaluate the safety, tolerability, and efficacy of efdamrofusp alfa in patients with neovascular age-related macular degeneration (nAMD).

DESIGN:

Prospective randomized, open-label, multiple ascending-dose, phase 1b study.

METHODS:

Patients aged 50 years or older with active choroid neovascularization (CNV) secondary to nAMD were screened from 2 hospitals in 2 provinces in China. The first 9 patients were randomized 2:1 to intravitreally receive efdamrofusp alfa 2 mg at weeks 0, 4, and 8 or aflibercept 2 mg at weeks 0, 4, 8, and 16. After the dose-limiting toxicity assessment, 9 additional patients were randomized 2:1 to intravitreally receive efdamrofusp alfa 4 mg at weeks 0, 4, and 8 or aflibercept 2 mg at weeks 0, 4, 8, and 16. All patients were followed until week 20. Primary outcomes were safety and tolerability of efdamrofusp alfa. Secondary outcomes included changes from baseline in best-corrected visual acuity (BCVA), central subfield thickness (CST) as measured by spectral domain optical coherence tomography (SD-OCT), and CNV area as measured by fluorescein angiography (FA).

RESULTS:

A total of 18 patients were enrolled. Six each of them received efdamrofusp alfa 2 mg, efdamrofusp alfa 4 mg, or aflibercept 2 mg, respectively. No dose-limiting toxicity was reported, and all patients completed the study. No ocular serious adverse events were reported. All ocular treatment-emergent adverse events were intravitreal injection related and were mild or moderate in severity. At week 20, mean changes from baseline in BCVA were 5.64 ± 3.56, 8.93 ± 3.59, and 7.92 ± 3.55 letters for patients receiving efdamrofusp alfa 2 mg, efdamrofusp alfa 4 mg and aflibercept 2 mg, respectively. Meanwhile, CST and CNV area reductions indicative of anatomic improvement were observed in the majority of the patients receiving both doses of efdamrofusp alfa and aflibercept.

CONCLUSIONS:

Intravitreal efdamrofusp alfa dosed up to 4 mg every 4 weeks was well tolerated in nAMD patients with similar vision acuity and anatomic improvements.

Antiangiogenesis therapies targeting vascular endothelial growth factor (VEGF) have revolutionized the treatment of neovascular ocular diseases, including neovascular age-related macular degeneration (nAMD). Compelling evidence has implicated the vital role of complement system dysregulation in AMD pathogenesis, implying it as a potential therapeutic strategy for geographic atrophy in dry AMD and to enhance the efficacy of anti-VEGF monotherapies in nAMD. This study reports the preclinical assessment and phase 1 clinical outcomes of a bispecific fusion protein, efdamrofusp alfa (code: IBI302), which is capable of neutralizing both VEGF isoforms and C3b/C4b. Efdamrofusp alfa showed superior efficacy over anti-VEGF monotherapy in a mouse laser-induced choroidal neovascularization (CNV) model after intravitreal delivery. Dual inhibition of VEGF and the complement activation was found to further inhibit macrophage infiltration and M2 macrophage polarization. Intravitreal efdamrofusp alfa demonstrated favorable safety profiles and exhibited antiangiogenetic efficacy in a nonhuman primate laser-induced CNV model. A phase 1 dose-escalating clinical trial (NCT03814291) was thus conducted on the basis of the preclinical data. Preliminary results showed that efdamrofusp alfa was well tolerated in patients with nAMD. These data suggest that efdamrofusp alfa might be effective for treating nAMD and possibly other complement-related ocular conditions.

Bispecific vs. Bispecific: Innovent Announces First Patient Dosed in the Phase 2 Clinical Study of Efdamrofusp Alfa (IBI302), a First-in-class Anti-VEGF and Anti-Complement Bispecific Fusion Protein for the Treatment of Diabetic Macular Edema

SAN FRANCISCO and SUZHOU, China, May 6, 2025 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (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&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, " 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." Dr. Lei Qian, Senior Vice President of Clinical Development of Innovent, stated, "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." About diabetic macular edema Diabetic 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.

Innovent Announces Oral Presentation of Full Phase 2 Clinical Data for Efdamrofusp Alfa (IBI302), First-in-class anti-VEGF/complement Bispecific Fusion Protein at ARVO 2025

SAN FRANCISCO and SUZHOU, China, May 5, 2025 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, announces that the latest 1-year results from its Phase 2 clinical trial of efdamrofusp alfa (R&D code: IBI302), a recombinant human vascular endothelial growth factor receptor (VEGFR)-antibody human complement receptor 1 (CR1) fusion protein, in Chinese subjects with neovascular age-related macular degeneration (nAMD) were presented orally at the 2025 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO). The ARVO Annual Meeting 2025 is the premiere gathering of researchers and physicians in vision and ophthalmology to share the latest research findings and collaborate on innovative solutions, to be held from May 4 - 8 in Salt Lake City, Utah, U.S.. Title: Intravitreal High-dose Efdamrofusp Alfa (IBI302) in Patients with Neovascular Age-related Macular Degeneration: A Randomized, Double-masked, Active-controlled, Phase 2 Study Presentation Number: 443 Presentation Format: Speech/Mini Oral Presentation Time: May 4, 2:15pm-2:30pm Presenter : Prof. Xiaodong Sun, Shanghai General Hospital Affiliated to Shanghai Jiao Tong University School of Medicine The data were from the Phase 2 clinical study of high-dose IBI302 (NCT05403749) to evaluate the efficacy, safety and dosing intervals in patients with nAMD over a one-year treatment period. A total of 132 subjects were randomized 1: 1: 1 to IBI302 6.4 mg group, IBI302 8.0 mg group, or Aflibercept 2.0 mg group. After the loading therapy, IBI302 groups were administrated at personal treatment interval of Q12W or Q8W based on the disease activity assessed at Week 20. Subjects in Aflibercept 2.0 mg group were dosed Q8W after the loading therapy. The primary endpoint was the change in best corrected visual acuity (BCVA) in the study eye from baseline to week 40 and the study lasts 52 weeks. The results showed 6.4 mg/ 8.0 mg IBI302 competitive efficacy and safety profiles: Potential for extended dosing interval regiment: Throughout the trial period, over 80% of participants in IBI302 groups maintained visual benefits with a 12-week dosing interval. Comparable BCVA gains versus 2.0mg Aflibercept ： The trial met the primary endpoint, BCVA gains in 6.4mg/8.0mg IBI302 were noninferior to Aflibercept at week 40 ，the mean change from baseline +10.5[SD 9.6], +11.0[11.4], and +9.8[8.7] ETDRS letters, respectively. This improvement was sustained through week 52 with +10.8 [10.2], +11.3 [10.3], and +10.0 [9.0] letters compared to baseline. Anatomical efficacy improvement versus 2.0mg Aflibercept: At week 52, the mean change of central subfield thickness (CST) reductions from baseline was 154.58 [149.17] μm for the IBI302 6.4 mg group, 174.69 [147.04] μm for the IBI302 8.0 mg group, and 131.18 [102.91] μm reduction for the Aflibercept 2.0 mg group, respectively. Potential to inhibit macular atrophy: Data from pooled analyses of two Phase 2 clinical trials (CIBI302A201 and CIBI302A202) suggested that IBI302 treatment may reduce the incidence of MA at Week 52 by nearly 40% compared to aflibercept (4.9% in IBI302 groups vs. 8.3% in Aflibercept group) . The incidences of adverse events in IBI302 groups were similar to Aflibercept. No retinal vasculitis occurred in this trial. No new safety signals were identified. Professor Xiaodong Sun, Principal Investigator of the Study, Deputy director, Head of National Center for Clinical Ophthalmology, Shanghai General Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, stated: "It is my privilege to present the latest research findings on IBI302 to the global ophthalmic community at the ARVO meeting as the principal investigator. While anti-VEGF drugs remain the first-line therapy for nAMD, the frequency of intravitreal injections and follow-up visits can significantly impact patient compliance. Current drug development focuses on multi-target strategies and extended dosing intervals to reduce the treatment burden by decreasing injection frequency. Notably, IBI302—a novel global first-in-class bispecific molecule (anti-VEGF/anti-complement) —recently reported Phase 2 data showing that its high-dose cohorts met the primary endpoint. The treatment group achieved approximately 10-letters improvement in visual acuity from baseline at one year, with over 80% subjects demonstrating potential for at least 12-weeks extended dosing intervals. Additionally, preliminary observations in IBI302 group suggest potential efficacy in inhibition of macular atrophy. We anticipate this innovative therapy will successfully complete the Phase 3 registration trial, providing nAMD patients with more effective, patient-friendly options." Dr. Lei Qian, Senior Vice President of Clinical Development of Innovent, stated: "We are honored to present the latest progress of IBI302 in its second Phase 2 clinical trial at the ARVO annual meeting. High dose IBI302 demonstrates positive efficacy in visual acuity and anatomical improvements, while extend dosing intervals and potential anti-macular atrophy effects. Additionally, no new safety signals were observed during the trial, further validating the favorable safety and tolerability profile of this agent. These encouraging results establish a robust foundation for subsequent development. We will continue collaborating with clinical experts to expedite the Phase 3 clinical trial program, and accelerate the availability of this innovative therapy for patients with nAMD."

Innovent Biologics Faces Three Major Crises: Escalating Losses, Failed PD-1 Overseas, Unclear Path to Internationalization!

The investment in Fortvita, the market is highly concerned about the actions of innovative pharmaceutical companies, which is a supervisory force, which is also increasingly normal for innovative pharmaceutical companies. At the same time, a good company should be able to stand up to and respect multiple opinions. So can a persuadable creature of faith still be trusted? After the emotion, the debate has calmed down, or to return to the main line of investment growth logic. Innovent Biologics is facing three key changes: break-even, the birth of pharmaceutical king, and internationalization, which means value enhancement. After the PD-1 encountered obstacles at sea, Innovent Biologics had a deep sense of crisis, and pursued efficiency and fine management through a low-key bottom-up route, and miraculously supported a huge R&D pipeline with robust R&D expenditure. The product revenue of Innovent Biologics 2024Q3 exceeded 2.3 billion yuan, an increase of 40% year-on-year and 15% quarter-on-quarter. In the last four quarters, product revenue has climbed continuously, which is better than expected, verifying the excellent strength of domestic commercialization capability. Unlike most Biotech companies, Cinda no longer only looks at the situation of a single product, but wins with a diversified product matrix, which is similar to the robustness of traditional pharmaceutical companies Hengrui Pharmaceutical and China Biopharmaceutical. According to IQVIA statistics, in 2024H1, the total patient share of listed PD-(L)1 in China was the first for Xinda Biobasu, with a total share of 56% together with Beigene Beizan, and the market pattern was still relatively concentrated. As a cornerstone drug for cancer treatment, PD-1 market share is crucial, representing the right of pharmaceutical companies to speak in the field of cancer drugs. Innovent Biologics has crossed the death valley of the life cycle of innovative pharmaceutical companies, is sprinting to the break-even line, 2024H1 loss convergence to 393 million yuan, 2025 is expected to achieve adjusted EBITDA breakeven. This is all based on endogenous product revenue, rather than transient external BD licensing revenue. Cinda Bio-Mastal peptide is the world's first GLP-1R/GCGR dual-target agonist in the NDA stage, with NDA applications submitted in January 2024 for weight loss indications and NDA applications submitted in August 2024 for Type II diabetes indications, and both indications are expected to be approved for marketing in the first half of 2025 at the earliest. Compared with competing products (Simeaglutide, Tipotide), Maaldotide has a strong weight loss effect, and the 9mg group achieved a better weight loss benefit of 18.6% at 48 weeks when the average BMI and average body weight were higher at baseline. In addition to weight loss, Masidin is more worthy of expectation in terms of comprehensive metabolic benefits. The improvement of fatty liver was more obvious, activated liver GCGR, promoted fatty acid oxidation and lipopolysis, and the phase III clinical results showed that the liver fat content decreased by 80.2%, which was better than GLP-1R single agonist and other double-target agonists. Cinda has proven its commercialization efficiency, and Masaldopeptide as a super drug is about to explode the market. In the field of cardiovascular metabolism, there are high-potential products such as Symbila (PCSK9), which was approved for market last year, and Tetuzumab for thyroid ophthalmopathy, which is expected to be approved next year. Ophthalmology, free of large products are expected to be approved within 1-2 years. Tetuzumab (IGF-1R) was accepted as the NDA for the treatment of thyroid eye disease in May 2024, which is the first IGF-1R antibody to be declared for market in China, which will be a breakthrough variety exclusive to Cinda in this field; Piconcibezumab (IL-23p19) in the treatment of plaque psoriasis has potential better efficacy and advantages of long interval administration, and has been submitted for application. IBI302 is the world's first VEGF/ complement dual-target molecule in the treatment of stage 3 age-related macular degeneration. In recent years, we have also seen that Innovent Biologics is preparing for internationalization. The first is the layout of a new generation of innovative technology and self-research pipeline, involving ADC, double antibody, multi-antibody, small nucleic acid, in the first half of this year, self-developed varieties IBI343 (CLDN18.2 ADC) and IBI363 (PD-1/IL-2) disclosed preliminary clinical phase I data, showing positive early clinical signals. Secondly, the company invests more resources to simultaneously carry out overseas early clinical research and expand overseas research and development teams. It can be seen that the company attaches great importance and prudence to internationalization. From the appearance of the sea platform Fortvita, the company is still in a very early stage, the risk is extremely high, most of them are pre-clinical research and development projects, there is no pipeline assets to reach overseas POC, the layout is related to antibodies, involving tumor, non-tumor fields, similar to listed companies. It does not yet have production and sales functions. We seem to see that the muscle memory of the last failure is still dull, and Cinda Biology is extremely cautious about the first step of internationalization. Fortvita's current situation and direction are unclear, which precisely shows that internationalization is still in the exploratory stage. It is not ruled out to open other channels or ways to go to sea, License-out, NewCo model, cooperative development are all potential options, everything is full of variables. It is in the midst of uncertainty that management is prepared to demonstrate its commitment to internationalisation with real money, and that the market is too quick to judge the ethics of management. Even if the deal is withdrawn now, Fortvita's independent sea is still a proposition that Xinda and shareholders need to solve jointly. In any case, the internationalization of Innovent Biologics is also like an arrow from the string, there is no turning back, and it will eventually be achieved. China's new drugs are trekking a difficult road, fortunately has run out of a small number of leading companies, the fate is not tied to a clinical trial or business progress. Compared with the broad fundamentals of Xinda, this controversial event is just a small floating cloud, which will not shake the value of Innovent Biologics.
