• VIS-101, purpose-designed to be best-in-class for retinal vascular diseases, is a tetravalent, dual VEGF-A X ANG-2 inhibitor
• Topline Phase 2a data show VIS-101 provides rapid, robust and durable treatment responses in wet AMD
• VIS-101 demonstrated mean BVCA improvements of >10 ETDRS letters and median CST reductions of 100-150 mm
• Potentially best-in-class durability with a favorable safety profile and no dose-limiting toxicity
• Phase 2b dose-determining study expected to begin in H2 2026; global Phase 3 program expected to begin in 2027

SHANGHAI, March 13, 2026 /PRNewswire/ -- Everest Medicines (HKEX: 1952.HK) today announced that its licensing partner, NovaBridge Biopharma (NASDAQ: NBP, "NovaBridge"), together with its subsidiary Visara, Inc. ("Visara"), reported positive topline results from the Phase 2a study of VIS-101, a purpose-designed tetravalent, dual VEGF-A X ANG-2 inhibitor in development for retinal vascular diseases including wet age-related macular degeneration (wet AMD), diabetic macular edema (DME), and retinal vein occlusion (RVO). Topline results show that VIS-101 produced rapid, robust and durable treatment responses in wet AMD, with potential best-in-class durability and a favorable safety profile. Wet AMD affects more than 20 million people globally^[1].

Topline Data:

VIS-101 produced rapid and robust efficacy, and durable treatment responses with both 3 mg and 6 mg dose cohorts:

• Mean improvement in Best Corrected Visual Acuity (BCVA) of >10 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters
• Median central subfield thickness (CST) reduction of 100-150 mm
• Potential best-in-class durability with:
  • ~two thirds of patients retreatment-free at 4 months
  • ~half of patients retreatment-free at 6 months
• Favorable safety and no dose limited toxicity

"We congratulate our partner on the positive top-line results from the VIS-101 Phase 2a study, marking an important milestone in its clinical development. Dual VEGF-A/ANG-2 inhibition has been validated as a key approach for treating retinal vascular disease, and extending treatment durability remains a critical unmet need," said Rogers Yongqing Luo, Chief Executive Officer of Everest Medicines. "VIS-101 has demonstrated potentially best-in-class durability, robust visual and anatomic improvements, along with a favorable safety profile, providing a strong foundation for advancing its future clinical development. With Everest's experience in clinical development and commercialization, we look forward to bringing VIS‑101, a highly differentiated bifunctional antibody with strong commercial potential, to patients across China and Asia in the near future."

"I am encouraged by the positive Phase 2a safety and efficacy data as it provides important proof-of-concept for VIS-101 as a potential treatment for wet AMD. The data validates VIS-101's purpose-engineered design and gives us added confidence in its potential to deliver best-in-class durability while maximizing visual gains in the treatment of wet AMD," said Emmett T. Cunningham, Jr., MD, PhD, MPH, Founder and Executive Chairman of Visara and Vice-Chairman of the NovaBridge Board of Directors. "The data clearly show that VIS-101 produced rapid, robust and durable treatment responses, with favorable tolerability, after three loading doses. Importantly, VIS-101 also demonstrated potential best-in-class durability, with nearly half of treatment naïve patients remaining retreatment free for more than six months following induction. Such strong clinical results provide a meaningful foundation to advance our development program, including plans to initiate a dose-determining Phase 2b study in the second half of this year, followed by a global Phase 3 program in 2027."

On October 30, 2025, Everest Medicines entered into a collaboration agreement with Visara, under which Everest acquired an exclusive license to develop, manufacture, and commercialize VIS-101 in Greater China, Singapore, South Korea, and certain Southeast Asian countries.

About the Randomized Phase 2a Study of VIS-101 in Wet AMD

Patient Characteristics:

The study enrolled 38 patients in China, aged 50-80 years of age with wet AMD (both treatment naïve and pre-treated). Patients were randomized 2:1 between 6mg dose (n=25) and 3 mg (n=13). Baseline characteristics were similar between both dose groups (noting a slightly higher proportion of pre-treated patients in the 6 mg dosing group).

Baseline Patient Demographics: Similar between dosing groups

Safety: VIS-101 Demonstrated a Favorable Safety Profile With No Dose-Limiting Toxicity

• The total treatment-related treatment emergent adverse events (TEAEs) were 0% (n=0) in the 3 mg dose and 8% (n=2) in the 6 mg dose, with 1 event each in two separate patients.

About the Randomized Phase 2a Study of VIS-101 in Wet AMD

The Phase 2a randomized study (NCT05456828) evaluated the safety and efficacy of VIS-101 (aka AM712 or ASKG712) in patients with wet AMD, including patients who were naïve to treatment or VEGF-experienced. The study enrolled a total of 38 wet AMD patients in China.

Patients were randomized 2:1 to 6mg VIS-101 (n=25) or 3 mg VIS-101 (n=13). The primary endpoint was safety and pharmacokinetics and the secondary endpoint was efficacy, measured by best corrected visual acuity (BCVA) change from baseline (assessed by early treatment diabetic retinopathy scale (ETDRS Letters), change in central subfield thickness (CST, measured in mm), and retreatment rate. Subjects were given three loading doses at weeks 0, 4 and 8, with monthly follow-up to week 36 or retreatment (based on protocol-defined Disease Activity Criteria based on BCVA, CST and wet AMD activity). Safety and efficacy endpoints were assessed at each visit including 24 weeks (6 months) after the last loading dose.

About VIS-101

VIS-101 (also known as ASKG712 or AM712), purpose-designed to be best-in-class, is a dual VEGF-A X ANG-2 inhibitor in development for the treatment of retinal vascular diseases, such as wet AMD, diabetic macular edema (DME) and retinal vein occlusion (RVO), which affect more than 57 million people globally^[1]. VIS-101's bispecific, tetravalent design format provides more binding sites and increased VEGF-A and ANG-2 affinity, for rapid, robust and class-leading durable responses. VIS-101 has completed initial safety and dose-escalation studies in both the US and China and a randomized, dose-ranging 2a study in China (NCT05456828). VIS-101 is expected to advance to a dose-determining Phase 2b study in 2026, with initiation of the global Phase 3 program in 2027.
