Diabetic Macular Edema (DME)

A Phase 3, Randomized, Double-Masked, Active-Controlled Trial to Evaluate the Safety, Efficacy, and Durability of a Single Intravitreal Injection of 4D-150 versus Aflibercept in Adults with Diabetic Macular Edema (4SIGHT)

Our current goals include confirming inflammation mediators are biomarkers of DR and DME The Aim of this project is to measure aqueous PGE2 and inflammatory cytokines before and after treatment of DME with intravitreal corticosteroid injections. We want to continue the study for one more year as our initial data analysis from the original INSPIRE study shows a possible direct correlation between aqueous biomarkers and DME. We propose treating the DME with corticosteroid to assess the effect upon the intraocular cytokines with inflammation is suppressed.

This is a Phase 3 study of an investigational drug called OLN324, which is being developed by Ollin Biosciences as a treatment for patients with diabetic macular edema (DME).

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 is a Phase I, multicenter, open-label, dose-escalation study conducted in two parts to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GenSci148 administered via intravitreal (IVT) injection in participants with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO). Part 1 evaluates single ascending doses in nAMD participants. Part 2 evaluates multiple doses in nAMD, DME, and RVO participants. The study also assesses immunogenicity and explores preliminary efficacy.

The purpose of this study is to learn about the effects of BGE-102 on change in vision in participants with center-involved diabetic macular edema (CI-DME). BGE-102 decreases inflammation which may improve vision or slow the progression of vison loss in those with CI-DME. Participants will be randomized to one of 3 arms and receive either BGE-102 in combination with an anti-vascular endothelial growth factor (anti-VEGF) drug, BGE-102 in combination with sham injection, or BGE-102 placebo in combination with an anti-VEGF drug. This study will also evaluate safety and tolerability of BGE-102.

A Study to Evaluate the Efficacy and Safety of Tabirafusp Tedromer Compared to Aflibercept in Participants with Diabetic Macular Edema - ALTO

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.

The goal of this clinical trial is to see if treatment with faricimab or biosimilar ranibizumab leads to different early imaging changes in adults with diabetic retinopathy requiring anti-VEGF treatment and to identify OCT and OCTA biomarkers predictive of differential early treatment response between the two therapies. The main questions it aims to answer are: Which OCT and OCT angiography biomarkers predict early treatment response? How do imaging biomarkers change after three loading doses of treatment? Are imaging biomarkers associated with systemic laboratory parameters? Researchers will compare faricimab to biosimilar ranibizumab to see if there are differences in imaging biomarkers and early treatment response. Participants will: * be randomized in a 1:1 ratio using a computer-generated randomization sequence * undergo comprehensive ophthalmic examinations, including visual acuity and intraocular pressure measurement * undergo OCT and OCT angiography imaging at each visit * receive three intravitreal injections during the loading phase * attend follow-up visits from baseline to 4-5 weeks after the third injection * provide blood samples for systemic laboratory analysis

A multicenter, randomized, double-blind, parallel-group, active-controlled non-inferiority trial. A total of 406 subjects with diabetic macular edema (DME) were planned for enrollment. After screening, eligible subjects were randomized in a 1:1 ratio to the treatment group or the control group. The treatment group received BAT5906 injection, while the control group received Lucentis®. During the trial, ophthalmic examinations and safety assessments were conducted according to the protocol for efficacy and safety evaluation. Blood samples were collected for immunogenicity assessment. The primary endpoint was the mean change in best-corrected visual acuity (BCVA) in the study eye from baseline to week 52 (measured using the ETDRS chart).

The goal of this study is to evaluate the safety and efficacy of LX111 treatment of DME. This study will enroll participants aged ≥ 18 vears old to receive a single unilateral intravitreal (lVT) injection of LX111 to evaluate its safety and efficacy.

This phase 2b trial is a randomized, double-masked, parallel-group, multi-center study in approximately 156 patients with DME to evaluate the efficacy and safety of CU06-1004 orally administered once daily for 24 weeks. The study will have a 1:1:1 randomization (CU06-1004 200mg: CU06-1004 300mg: Placebo).

This is a 12-month, prospective, randomized controlled, multi-center, open-label, superiority designed study. Treatment-Naïve DME patient with inflammatory biomarkers, who meet the inclusion and exclusion criteria, will be recruited. This study aims to provide the first direct comparative evidence within a Chinese cohort, evaluating the efficacy and safety of a combined DEX-I plus aflibercept therapy versus aflibercept monotherapy for DME. The investigation will focus on functional visual outcomes, anatomical improvements, and the respective safety profiles associated with each treatment regimen. Furthermore, the study will incorporate specific optical coherence tomography (OCT) biomarkers to refine patient selection, with the goal of enhancing the precision of identifying candidates for combination therapy. It is hypothesized that the combination therapy, by concurrently targeting both VEGF-mediated and inflammatory pathways, may yield superior clinical outcomes compared to monotherapy.

Objective of this randomised controlled trial is to compare the efficacy of a single per operative anti VEGF injection with repeated postoperative anti VEGF injections in the prevention of diabetic retinopathy progression after cataract surgery. This Randomised Controlled Trial (RCT) will be conducted at Sahiwal Teaching Hospital and University College of Medicine \& Dentistry Lahore. Duration of study will be from January 2026 to September 2026. This study will be single blind and parallel group research. The study will include diabetic patients of both sexes ≥ 40 years of age presenting with non-proliferative diabetic retinopathy and cataract. Exclusion criteria include proliferative diabetic retinopathy, center-involving diabetic macular oedema (DME), poor glycemic control (HbA1c \>9%), glaucoma, uveitis, prior ocular surgery or laser, and recent systemic thromboembolic events. Subjects will be randomly divided into two groups, each containing 83 subjects. Standard phacoemulsification with intraocular lens implantation will be performed in all participants. A single intra vitreal Aflibercept injection ( 2mg/0.05 ml ), will be given to group 1 participants. While, group 2 participants will receive an intra operative injection plus two additional injections at 1 month and 2 months postoperatively. For all participants, follow up will be performed at 1 week, 1 month, 2 month, 3 month and 6 month. Primary Outcome include progression of diabetic retinopathy (DR) severity (≥1 stage according to the guidelines of the international clinical diabetic retinopathy disease severity scale ICDR) or onset/progression of DME. Secondary Outcomes include changes in best corrected visual acuity, changes in central macular thickness (CMT), and need for rescue treatment. SPSS version 26 will be utilised to analyse the data. P ≤ 0.05 will be taken as statistically significant. Qualitative variable like diabetic retinopathy grading and diabetic macular oedema status will be analysed by utilising Pearson's chi-square test. Quantitative variables like central macular thickness will be analysed by employing t-test.

Patients with diabetic macular edema (DME) sometimes must undergo vitrectomy surgery (PPV) for diabetic and non-diabetic related issues. Patients may have improved DME with anti-VEGF therapy and ranibizumab has been found to reduce central macular thickness (CMT) with anti-VEGF therapy following vitrectomy. Those patients still require intravitreal injections but the pharmacokinetics of a vitrectomized eye are different than those eyes that have not undergone vitrectomy. The clearance of protein molecules is quicker in vitrectomized eyes so these patients may be more refractory to standard of care anti-VEGF therapy. In rabbit models, the half-life of both bevacizumab and ranibizumab were reduced by a factor 1.8 and 1.3, respectively, after pars plana vitrectomy. In a study examining intravitreal triamcinolone acetonide in human eyes, the half-life was found to be 18.6 days in non-vitrectomized eyes and 3.2 days in vitrectomized eyes, but there was considerable intrasubject variation. Patients with various disease states, including neovascular age-related macular degeneration (nAMD) have been managed with monthly anti-VEGF therapy successfully after vitrectomy surgery. Another study performed by the DRCR net showed that patients with DME treated with anti-VEGF are not affected in the long term if they had had a previous vitrectomy. High dose aflibercept may improve anatomic and visual outcomes in this patient population. Also, high dose aflibercept may allow for longer treatment intervals in these vitrectomized eyes.

This study aims to investigate the impact of intravitreal injection of anti-vascular endothelial growth factor (anti VEGF) Faricimab on renal function of diabetic patients. Faricimab is a new anti-VEGF drug which inhibits both VEGF-A and Ang-2 and it is used for the treatment of diabetic macular edema and neovascular age related macular degeneration. It is known that previous anti-VEGF agents has systematic absorption and may cause deterioration in renal function of the patients. However, the effect of Faricimab on kidney function has not been investigated yet. Taking into account that Ang-2 has destructive effect on kidneys, the investigation of the effect of its inhibition in diabetic patients who have already renal function deterioration may provide a valuable information in scientific community.

Diabetes mellitus is a disorder of sugar and fat metabolism which results in damage to the small blood vessels in various organs, this includes the retina - the part of the eye that processes light into a nerve impulse. This leads to damage and blindness via various different mechanisms that are not fully understood. In this study the objective is to recruit people with diabetes and various stages of diabetic eye disease and measure a large number of different chemicals within the blood that might be associated with damage and dysfunction within the retina. Additionally, it will examine the different bacteria within the gut that might affect disease in the eye via chemicals circulating in the blood. This will require participants to have blood samples taken and to provide urine samples. The blood will be analysed with specialised instruments to identify specific molecules circulating within the blood. Participants will also need to allow researchers to look at their medical records, previous photographs and specialist scans of the back of the eye to grade their diabetic retinopathy. This will allow us to identify potential ways in which these could be targeted for future benefit for people with diabetes to hopefully prevent deterioration of their vision.

The study is a randomized, double-blind, placebo-controlled, phase 1 study of JMKX003948 Ophthalmic Suspension to evaluate the safety, tolerability and PK of single and multiple ascending doses in healthy participants. Participant will be randomized to receive either JMKX003948 Ophthalmic Suspension (1%, 2%, 3% or 5%) or matching placebo (JMKX003948 Ophthalmic Suspension: placebo= 6: 2, N=8 per cohort). Five cohorts (Cohort 1-5) are planned. Cohorts could also de-escalate to a lower concentration if current formulation was not tolerated (Cohort 1b, 2b and 3b). In case of de-escalation, Cohort 1b and 2b will continue to escalate to Cohort 1c and Cohort 2c, respectively. Participants will be admitted to the site on Day -1 after screening (up to 28 days), and remain domiciled until Day 14 for Cohort 1-4, Day 8 for other cohorts.
