Integrative Liver-Targeted Therapy for Diabetic Macular Edema: Using "Tauroursodeoxycholate" or Traditional Chinese Medicine.

Diabetic macular edema is seen in the later stages of diabetic retinopathy with current conventional therapies targeting local vascular dysfunction. These therapies provide transient improvement in vision and are often uncomfortable to persons with diabetic macular edema and financially burdensome. Diabetic macular edema, a complication of diabetes cannot be managed without addressing systemic inflammation. Liver metabolism and functions are implicated in diabetes and evidence suggests that hepatic metabolic dysfunctions are linked to the neuroinflammation and vascular dysfunctions observed in diabetic retinopathy. Nutraceutical supplements like Tauroursodeoxycholate (a bile acid) and modified Qi Ju Di Huang Wan (a traditional Chinese medicine formula) have been found to reduce hepatic and retinal oxidative stress, provide anti-apoptotic, anti-inflammatory, neuroprotective and hepatoprotective effects. This study will provide a non-invasive multi-targeted strategy for the management of diabetic macular edema.

Effectiveness of Intravitreal Injection of Aflibercept 8 mg in Resistant Diabetic Macular Edema, Retinal Vein Occlusion and Myopic Choroidal Neovascularisation Patients

Generally, DM is caused by insufficient insulin secretion in the body; however, the other biological mechanisms remain unclear. Long-term illness in patients with DM damages various organs in the body, such as the eyes, kidneys, and heart, seriously affecting organ function. Nowadays, the quality of life of people has improved significantly, eating habits have changed, sugar intake is increasing, and the number of patients with DM is increasing. Statistics show that in 2017, the number of patients with DM worldwide reached 425 million (aged 20-79 years), which will exceed 600 million in 30 years; moreover, patients in low- and middle-income countries, such as China and India, account for 80 percent of the total DM population (1). According to the WHO, patients with DM worldwide increased to 366 million in 2011, which is expected to increase to 500 million in 2025, with more than 150 million patients experiencing ocular complications, such as diabetic retinopathy (DR) (2, 3). DR is a form of ocular microangiopathy and the most serious DM-related complication; it seriously endangers the health of patients with DM (4). DR pathogenesis includes increased endothelial cells in the eye capillaries, increased intimal thickness, damaged pericytes, microangioma, and damaged blood-retina barrier due to increased permeability of the blood vessels, microvascular obstruction, and neovascularization (NV) (5, 6). Currently, the prevalence of DR is 34.6% worldwide; however, it is higher in some developed countries, reaching 40.3% (7). The proportion of patients with type 1 and 2 DM suffering from blindness due to DR is 3.6% and 1.6%, respectively (8). DR is associated with significantly reduced living standards, huge medical costs, and increased social burden (9, 10). Many anti-vascular endothelial growth factor (VEGF) drugs exist; however, the use of therapeutic drugs is strictly controlled. The main drugs recommended for treating DM-related visual complications are ranibizumab and aflibercept.

A First-in-human Trial of SZN-8141 in Diabetic Macular Edema

DUET (Cl-8141-1001) is a first-in-human clinical trial evaluating the safety, tolerability, pharmacokinetics (how the body processes the study drug), and preliminary biological activity of SZN-8141 in people with diabetic macular edema (DME). In this study, small groups of participants with DME (approximately three participants per dose group) will receive a single injection of SZN-8141 into the eye and will be followed for approximately 3 months. During the trial, participants will undergo regular assessments to monitor their overall health and eye condition. These assessments include eye examinations, vision testing, retinal imaging, laboratory testing, and blood sample collection to measure levels of SZN-8141 in the bloodstream and to assess whether the body develops anti-drug antibodies. The trial uses an ascending-dose design, in which successive groups of participants receive increasing dose levels of SZN-8141. Safety and tolerability data from each dose group will be reviewed before the next higher dose level is evaluated.

This study is a prospective, non-interventional, multicenter, open-label study in nAMD and DME patients being treated with brolucizumab according to the EU SmPC. An observational study design, without a strict, mandated visit schedule or mandated treatment regimen was chosen as the most appropriate to collect available data in a real life setting. For that reason, this NIS does not impose a therapy protocol, diagnostic/therapeutic procedure or a visit schedule. The diagnostic or monitoring procedures are only those ordinarily applied to the therapeutic strategy and to routine clinical care and will take place as per investigator's discretion. This includes e.g. visit frequency, injection frequency and types of assessments performed - only data from routine medical practice will be collected as part of the study.

AI Prediction of Treatment Response in DME

Diabetic macular edema (DME) is a leading cause of vision loss among individuals with diabetes mellitus. Although intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy is the standard treatment for center-involved DME, treatment response varies considerably between patients. Recent advances in artificial intelligence (AI), including machine learning (ML) and deep learning (DL), have enabled automated analysis of retinal imaging biomarkers to predict anatomical and functional treatment outcomes. This study aims to systematically evaluate published evidence regarding AI-based prediction models and imaging biomarkers used to predict treatment response in patients with DME. The review will assess the predictive performance of AI models, identify the most important imaging biomarkers, compare different AI approaches and imaging modalities, and summarize methodological strengths, limitations, and research gaps to support future development of precision ophthalmology.

Zhuochuming®-3T&E-DME Study (Treatment-naïve Patients)

The goal of this clinical trial is to understand whether Zhuochuming® (Aflibercept Intravitreal Injection) using a 3 loading doses followed by a treat-and-extend regimen (3+T\&E) can treat patients with diabetic macular edema (DME) who have not received prior treatment. It will also evaluate the safety of Zhuochuming®. The main questions it aims to answer are: Can Zhuochuming® using the 3+T\&E regimen improve patients' vision better than the traditional pro re nata (3+PRN) regimen? How much can the macular edema (central retinal thickness) be reduced? What medical problems (ocular or systemic) will participants experience while taking Zhuochuming®? What is the difference in the number of injections needed over one year between the two regimens? Researchers will directly compare Zhuochuming® (3+T\&E regimen) with Zhuochuming® (3+PRN regimen) to see which regimen is more effective and convenient for treating DME. Participants will: Receive treatment and be followed for 52 weeks (about 1 year) First receive 3 injections (one every 4 weeks), and then continue according to their assigned group: T\&E group: Injection intervals are gradually extended (up to 16 weeks) based on disease stability PRN group: Follow-up visits every 4 weeks, with injections given only when needed Visit the clinic at scheduled times (e.g., before each injection or every 4 weeks) for eye examinations (visual acuity, intraocular pressure, OCT, etc.) Undergo regular blood tests (complete blood count, liver function, coagulation function, HbA1c, etc.) Record any discomfort or side effects and report them to the doctor Study population: Patients with diabetic macular edema (DME) who have not received prior treatment, aged ≥18 years, and diagnosed with type 1 or type 2 diabetes. Primary study endpoint: Change in best-corrected visual acuity (BCVA) from baseline at week 52.

Study to Evaluate an 8 mg Aflibercept (EYLEA®) Prefilled Syringe (PFS)

Regeneron Pharmaceuticals developed a single-dose pre-filled syringe (PFS) to deliver 8 mg aflibercept. The PFS is a convenient device that contains the study medication that will be injected in your study eye. A PFS offers a sterile, single dose of study drug within the syringe; this eliminates the need for the retina specialist to prepare the injection syringe from a separate vial. This Phase IIIb study is focused on patients with diabetic macular edema (DME) and neovascular (wet) age-related macular degeneration (nAMD). The main aim of the study is to evaluate if the 8 mg aflibercept PFS allows for successful preparation and administration of 8 mg aflibercept by retina specialists. The study will also assess the safety of 8 mg aflibercept PFS use. Regeneron will use the information from the study to better understand if the PFS can be used safely and effectively by retina specialists to administer 8 mg aflibercept.

A Study to Learn More About the Use of Aflibercept in Routine Medical Practice in Japanese Participants With Neovascular Age-related Macular Degeneration and Diabetic Macular Edema

This is an observational study in which data already collected from participants with neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME) is studied. In observational studies, only observations are made without participants receiving any advice or any changes to healthcare. The eye disorders, nAMD and DME, affect the macula, the central part of the retina at the back of the eye. This leads to blurry vision or blind spots, making everyday activities like reading or sewing difficult. While nAMD is linked to aging, DME is related to diabetes. Both conditions require similar treatment to help improve vision. Aflibercept 8 milligrams (mg) is already approved in Japan for doctors to prescribe to people with nAMD or DME. It is a drug injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF), which causes abnormal growth and leakage of blood vessels at the back of the eye. The participants in this study are already receiving treatment with aflibercept 8 mg as part of their regular care from their doctors. There is limited data available on the use of aflibercept 8 mg in Japan. Data from routine medical practice will inform treatment in Japanese and other Asian populations. The main purpose of this study is to learn more about the disease and patient characteristics of Japanese participants with nAMD and/or DME who receive aflibercept 8 mg during their routine healthcare, and how they use it. To learn this, the study will use 2 methods: Method 1: Researchers will study the health details of participants when they first started aflibercept 8 mg. Method 2: Researchers will study the participants' data collected over 1 year to see how they used aflibercept 8 mg. The data will come from a claims database called DeSC Healthcare Inc. The data will be collected from April 2023 to March 2025 for Method 1, and from April 2023 to March 2026 for Method 2. Researchers will only look at the information from participants in Japan. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.
