新生血管加齢黄斑変性症(AQUARIUS)患者におけるIxoberogene Soroparvovec(Ixo-vec)の有効性および安全性に関する研究 (AQUARIUS)

2026年9月22日 更新者:Adverum Biotechnologies, Inc.

新生血管加齢黄斑変性症(AQUARIUS)患者におけるIxoberogene Soroparvovec(Ixo-vec)の有効性および安全性を評価するための多施設共同、無作為化、二重盲検、活性対照薬対照、第3相試験

This is a multi-center, randomized, double-masked, active-comparator-controlled, Phase 3 study in a broad participant population (treatment-naïve and treatment-experienced) with neovascular (wet) age-related macular degeneration (nAMD). The study will evaluate a single intravitreal (IVT) injection of Ixo-vec compared to intravitreal aflibercept (active comparator). The primary endpoint of this study is the mean change in best corrected visual acuity (BCVA) of Ixo-vec compared to an active comparator measured as an average at Weeks 52 and 56.

Safety, tolerability, and efficacy will be evaluated throughout the study.

詳細な説明

The primary objective of this study is to evaluate the non-inferiority in efficacy of a single IVT injection of Ixo-vec 6 x 10^10 vector genome (vg)/eye compared to an active comparator. Non-inferiority will be evaluated using a pre-specified margin defined in the protocol.

Neovascular AMD is a degenerative ocular disease associated with the infiltration of abnormal blood vessels in the retina from the underlying choroid layer and is a leading cause of blindness in patients over 65 years of age. The abnormal angiogenic process in nAMD is stimulated and modulated by vascular endothelial growth factor (VEGF). Treatment of nAMD requires frequent IVT injections of VEGF inhibitors (anti-VEGF) administered every 4-16 weeks. Ixo-vec (also known as ADVM-022 or AAV.7m8-aflibercept) is an adeno-associated virus (AAV)-based gene therapy product being developed for the treatment of nAMD. Ixo-vec is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with nAMD receiving anti-VEGF therapy in clinical practice.

Safety, tolerability, and efficacy will be evaluated throughout this study. The primary endpoint of this study is the mean change in BCVA of Ixo-vec compared to an active comparator measured as an average at Weeks 52 and 56 post-treatment.

Due to the long duration of the Screening period, this study will be considered fully enrolled when randomization has been completed.

  5. History or evidence of any of the following cardiovascular diseases:

    1. Myocardial infarction in the 6-month period prior to Week 1.

  6. History of ongoing bleeding disorders. The use of aspirin or other anticoagulants (e.g., Factor Xa inhibitors) is permitted.

  7. Use of systemic immunosuppressive drugs within 90 days prior to Screening Visit 1. Short courses of oral corticosteroids are permitted, as well as any inhaled, intra-articular, nasal or dermal steroid use.

  8. Evidence of poorly controlled diabetes or glycated hemoglobin (HbA1c) ≥ 8.0% during screening.

Ocular Exclusion Criteria

  1. Any active ocular or periocular infection in the study eye from Screening Visit 1.

  2. History or evidence of the following in the study eye:

    1. Intraocular or refractive surgery within 5 months prior to Week 1.
    2. Any previous penetrating keratoplasty or vitrectomy.
    3. Any previous panretinal photocoagulation.
    4. Any previous submacular surgery, other surgical intervention (including port delivery system) or laser treatment for age-related macular degeneration.
  3. Any history or evidence of retinal detachment (with or without repair) or retinal pigment epithelium rip/tear in the study eye, as determined by the Investigator during screening or at Week 1.

  4. Uncontrolled ocular hypertension or glaucoma in the study eye from Screening Visit 1 to Week 1 or current use of ≥ 2 intraocular pressure (IOP) lowering medications or normal tension glaucoma/suspect in the study eye or history of any of the following procedures in the study eye prior to Week 1:

Mean Change in 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) Total and Subscale Scores
時間枠:Day 1 to Week 28 and Week 56

The NEI VFQ-25 measures vision-targeted patient-reported outcomes of individuals with chronic eye diseases. It comprises 25 questions. The assessment generates an overall composite score and includes the following subscales: global vision rating, difficulty with near vision activities, difficulty with distance vision activities, limitations in social functioning due to vision, role limitations due to vision, dependency on others due to vision, mental health symptoms due to vision, driving difficulties, limitations with peripheral and color vision, and ocular pain. A decrease in the NEI VFQ-25 score represents an improvement in disease severity.

時間枠:Day 1 to Week 28 and Week 56

The EQ-5D-5L is a concise, generic self-reported health questionnaire which is weighted to reflect the relevant importance to patients of various different health problems. In retinal disease, the questionnaire is used to assess quality of life in the context of vision loss. It measures five parameters; mobility, self-care, usual activities, pain/discomfort and anxiety/depression. An increase in the EQ-5D-5L score represents an improvement in disease severity.
