Clinical Trial Summary

This prospective non-randomized open-label interventional study aimed to evaluate feasibility in regard to potential efficacy and safety of triamcinolone acetonide (TA) injected in the suprachoroidal space (SCS) as a promising therapeutic route that provides a better bioavailability, longer sustained duration of action, and thus improved patients' compliance for the treatment of macular edema due to retinal vein occlusion (RVO).

Clinical Trial Description

Management of Macular Edema (ME) associated with Retinal Vein Occlusion (RVO) still poses a therapeutic challenge taking into account its complicated etiopathogenesis. Despite improved visual and anatomical outcomes achieved by intravitreal injections of antiangiogenics and steroids, these treatments are still associated with non-responders, tachyphylaxis, rebound phenomenon, high re-injection, and adverse events rates, which underscore the importance of addressing new approaches to formulate treatment strategies. Delivery of therapeutic agents into the suprachoroidal space (SCS) provides a novel alternative approach that has theoretical appeal, as it dominantly targets chorioretinal tissues with the posterior and circumferential spread of the drug administered while relatively sparing the unaffected anterior segment of the eye and the vitreous chamber, thus minimizing risks associated with off-target effects, which potentiates safety. This was well translated in preclinical and clinical studies through microinjector, which has been shown to provide a safe, minimally invasive, and reliable method of targeting SCS. In addition, sustained duration and favorable pharmacokinetics have been observed for small molecule suspensions including Triamcinolone Acetonide (TA), with the potential to reduce treatment burden. ;
