Active clinical trials for "Macular Edema"

Part A of the study is conducted to select the THR-149 dose level. Part B of the study is conducted to assess the efficacy and safety of the selected dose level compared to aflibercept, up to Month 3. As from Month 3, in about half of the subjects, the effect of a single flip-over injection (aflibercept or THR-149) will be evaluated when administered 1 month after the 3 monthly injections of THR-149 or aflibercept. In the other subjects, the durability of 3 monthly injections of THR 149 or aflibercept will be evaluated.

The purpose of this clinical trial is to compare safety, tolerability, efficacy, and durability of two dose levels of suprachoroidal sustained-release OXU-001 (dexamethasone microspheres; DEXAspheres®) using the Oxulumis® illuminated microcatheterization device compared with intravitreal dexamethasone implant (OZURDEX®) in subjects with diabetic macular edema.

To determine safety, pharmacokinetics, and duration of effect of periocularly administered AIV007 gel suspension in subjects with neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME).

Changes after suprachoroidal injection are analyzed for statistical analysis.

this study will compare the efficacy and safety of use either Ranibizumab and Aflibercept in treatment of macular edema resulting from non ischemic central retinal vein occlusion in patients younger than 5o years old

Diabetic Macular Edema is a serious ocular consequence of poorly controlled diabetes. Even though significant research has been done to clarify the pathogenesis of DME, a clear causal pathway of the complication is of yet undetermined. However, there is some consensus among researchers that a cascade of inflammatory markers plays an important role in the disease process. The study hopes to better delineate the role these inflammatory markers play by investigating whether basal levels predict response or lack thereof to Aflibercept.

Although the safety and efficacy of bevacizumab has been established in several phase 3 trials, there is only little documented about the long-term safety and efficacy in the 'real-world practice' in large populations from different regions. Therefore the investigators evaluate the long-term safety and efficacy of intravitreal treatment with bevacizumab by registration of best corrected visual acuity, side-effects and central retinal thickness as measured with the ocular coherence tomography if available. This will allow the investigators to compare the results of their centre with the results of several phase 3 trials from the literature and will guide improvements in their treatment protocols.

Objective: To determine the association between baseline aqueous cytokine levels and treatment intervals for patients under a variable dosing regimen with intravitreal ranibizumab in patients with neovascular age-related macular degeneration (nAMD), macular edema secondary to retinal vein occlusion (RVO) and diabetic macular edema (DME). Methods: A prospective, single-centre study will be performed containing 3 sub-studies according to each study population: nAMD, macular edema secondary to RVO and DME. Inclusion criteria are: patients followed at St. Michael's Hospital with the diagnosis of nAMD, macular edema secondary to RVO or DME. Patients will be excluded if visual acuity is worse than counting fingers, with macular pathologies causing any structural changes to the retina, have received anti-VEGF injections or photocoagulation therapy 6 months prior to study, intraocular surgery 3 months prior to study, any history of vitreoretinal surgery or ocular inflammation in the study eye, use of systemic or topical anti-inflammatory or steroids, patients on dialysis for renal failure, allergy to the study drug or fluorescein, <18 years old, women who are pregnant. All patients will be treated with ranibizumab intravitreal injections on a variable dosing regimen: Patients with DME will be examined monthly and receive mandatory injection for the first three months (baseline, weeks 4 and 8). Afterwards, they will continue to be seen monthly and the need for new injections will be decided upon the clinical findings at each visit. An anterior chamber (AC) tap will be done if an injection is required at the visit. Patients with nAMD and RVO will be examined monthly and receive mandatory injection for the first three months. From weeks 12 until 72 (month 18), the visits will be scheduled at increasing 2-weeks intervals based on the stability of the ocular condition and response to treatment. At each visit, an injection and AC tap will be performed. The maximum interval in between injections is 12 weeks. If the disease becomes unstable, the interval in between injections is shortened and, once it stabilizes, the treatment frequency is extended again. In all patients, baseline aqueous humour specimens will be obtained prior to the first ranibizumab intravitreal injection and follow-up samples will be taken immediately prior to subsequent injections based on the treatment regimens for cytokine analysis in the end of the follow-up.

This phase I trial will assess primarily the safety and secondarily the anti-inflammatory and anti-neovascular effect of Episcleral Celecoxib in patients suffering from macular edema and other inflammatory disorders of the retina, choroid and vitreous.

Phase 2 randomized, active-controlled, double-masked, dose-ranging trial in adults with Diabetic Macular Edema (DME).
