MMP-9 Inhibition for Recalcitrant Wet AMD

Wet (or neovascular) form of age-related macular degeneration (wAMD) is the most common cause of blindness in the Western world. Currently, anti-vascular endothelial growth factor (VEGF) intravitreal injections (IVI) remain the standard-of-care treatment for wAMD. Previous studies show that about 90% of treated patients lose minimal visual function after 2 years of follow-up. There is still, a subset of 15% patients, incomplete responders, that do not improve and possibly worsen due to the persistence of sub-retinal fluid (with or without intra-retinal fluid) with chronic treatment. The investigators plan to evaluate the effect of oral doxycycline versus placebo on the anatomic and functional outcomes in persistent sub-retinal eye fluid in neovascular wet age-related macular degeneration. This subset are incomplete or non-responders to current anti-VEGF intravitreal therapy.

Pivotal 1 Study of ABBV-RGX-314 (Also Known as RGX-314) Gene Therapy Administered Via Subretinal Delivery One Time in Participants With nAMD

ABBV-RGX-314 (also known as RGX-314) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD or nAMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (anti-VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to maintain or prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every 4 to 16 weeks in frequency, to maintain efficacy. Due to the burden of these treatments, patients often experience a decline in vision with reduced frequency of treatment over time.

Long-term Study of ADVM-022 in Neovascular (Wet) AMD [OPTIC-EXT]

ADVM-022-07 is an observational long-term extension (OPTIC-EXT) study assessing safety and efficacy of ADVM-022 gene therapy product, in participants with neovascular, or exudative (wet), age-related macular degeneration (nAMD).

User-centric Study of Patients' Receptiveness Towards the Web-based Automated Vision Impairment Gaze-tracking Analysis Systems

Age-Related Macular Degeneration (AMD) is the leading cause of central vision loss among older adults worldwide. Patients with AMD often require frequent monitoring of visual function and disease progression, typically through multiple follow-up visits involving optical coherence tomography (OCT), visual acuity testing (VA), and clinical consultations. While digital self-monitoring tools have emerged as promising solutions to reduce the burden of in-clinic visits, many elderly patients face challenges in engaging with these platforms due to visual impairment, limited digital literacy, and poorly optimised user interfaces. These barriers may reduce patient willingness to adopt such systems and undermine their long-term effectiveness. To address this gap, the study team has developed the web-based AVIGA (Automated Vision Impairment Gaze-tracking Analysis) system, which is a portable, self-administered, home-based digital monitoring system designed to minimise cognitive load and maximise usability for elderly AMD patients. The platform integrates patient-centred design principles such as simplified navigation, optimised text, and multimodal feedback (visual and audio) to empower users to independently track their visual health. A prospective, single-site usability trial to evaluate the AVIGA platform using validated human factors measures: the System Usability Scale (SUS), the Technology Acceptance Model (TAM) will be conducted. By examining the relationship between usability, cognitive load, and perceived empowerment, this study aims to identify critical user interface and user experience (UI/UX) design factors that influence willingness to adopt and sustain use of digital health tools among elderly AMD patients.

Automated Vision Assessment and Impairment Detection Through Gaze Analysis in Wet AMD Patients

The study aims to evaluate the Automated Vision Assessment and Impairment Detection through Gaze Analysis (AVIGA) system in the ability to detect and assess central vision dysfunction in a personalized, adaptive, objective, and automated way through eye gaze tracking in age-related macular degeneration (AMD). We also aim to develop a novel algorithm / scoring methodology for disease activity monitoring over time (delta-change). AVIGA visual risk prediction cut-off scores will be presented together with probabilities of occurrence of prespecified adverse clinical outcome.

Comparison of Rapid Aflibercept and Brolucizumab T&E in wAMD

The currently widely established and preferred protocol for the treatment of wet age-related macular degeneration includes a loading phase of three monthly injections without interim adaptation or treatment according to disease activity, thereafter following a T\&E strategy with treatment adaptation in increments of 2-4 weeks according to disease activity. Based on pharmacological considerations regarding the vitreal half-life of the drugs, the aim of this prospective explorative study is to test whether an early extension of treatment intervals without a loading phase is an option without compromising functional outcomes. Based on a superiority of Afl compared to Ran with regard to achieving a dry retina after one year and based on studies, but in the absence of real-life experience with Bro, it seems of interest to test how far Afl and Bro are comparable in terms of their potential to extend the treatment intervals over 12 months, the time to dryness of the retina, and number of injections. Also, it is of high clinical relevance to demonstrate efficacy with longer initial treatment intervals compared to the current possibly over-treating loading-phase with three four-weekly injections.

Pharmacogenomics of antiVEGF in Patients With Age-Associated Macular Degeneration (AMD)

This is a phase III, multicenter, randomized double-blinded clinical trial with two parallel groups (ranibizumab and bevacizumab) and an observational follow-up of patients who meet elegibility criteria and decline participation due to treatment randomization. It will be performed involving 630 eyes from patients with wet age-related macular degeneration (wAMD) diagnosis without another eye disease. This clinical trial compares the treatment response for 3 years, considering genetic variants already studied between the eyes treated with one of the first options of anti-VEGF used in patients with wAMD, (ranibizumab) and the most cost-effective anti-VEGF (bevacizumab; off-label use)

Evaluating the Safety and Preliminary Efficacy of EXG202 Gene Therapy for Neovascular AMD

VEGF inhibitors (anti-VEGF),such as aflibercept has been shown to be safe and effective for treating nAMD and have demonstrated improvement in vision. However, anti-VEGF therapy is administered frequently via intravitreal injection and can be a significant burden to the patients. EXG 202 is a recombinant adeno-associated virus (rAAV) gene therapy vector carrying a coding sequence for a soluble anti-VEGF protein. The long-term, stable delivery of this therapeutic protein following a 1 time gene therapy treatment for nAMD could potentially reduce the treatment burden of currently available therapies while maintaining vision with a favorable benefit.

A Long-term Follow up Study of EXG102-031 in Participants With wAMD

This is a long-term, safety and efficacy follow-up study of patients in the EXG102-031-111 gene therapy clinical trial for wAMD. Patients will complete visits from the parent study, and then into this long-term follow-up study for continuous safety monitoring for up to 5 years.

To Evaluate the Safety and Preliminary Efficacy of Intravitreal EXG202 Injection in Patients with Wet (neovascular) Age-related Macular Degeneration (wAMD)

The goal of this clinical trial is to evaluate the safety, tolerability and efficacy of intravitreal injection of EXG202 in subjects with neovascular age-related Macular Degeneration (nAMD).

Comparing Efficacy of 8-Week and 12-Week Faricimab Initial Follow-Up Treatment Intervals

This is a prospective, randomized study that compares 8-week and 12-week follow-up intervals after the 4 monthly injections in the loading phase. Patients with active CNV confirmed on optical coherence tomography (OCT) and OCT angiography (OCTA) will be randomized into two groups and followed for 44 to 56 weeks. Patients in the first group will receive 4 injections of faricimab every 4 weeks, with the next visit and injection after 8 weeks, followed by a treat-and-extend regimen with a minimal interval of 8 weeks and a maximal interval of 16 weeks. Patients in the second group will also receive 4 loading doses with the next visit after an extended 12-week interval. Following treatment, patients in this group will be on the same treat-and-extend regimen as patients in the first group. The study will compare best corrected visual acuity (BCVA), central retinal thickness (CRT) on OCT, and the number of injections between both groups.
