AbstractPatients with macular edema (ME) associated with uveitis (UME) are at risk for vision loss and decreased quality of life, and they often experience high health care costs and rates of workforce absenteeism. Systemically or locally delivered corticosteroids are the mainstay of treatment for UME. Although traditional corticosteroid treatments may demonstrate high levels of efficacy, systemic delivery carries the risk of potentially serious systemic adverse effects (AEs), and standard local modes of delivery may be associated with low bioavailability in posterior ocular tissues and steroid-associated AEs due to anterior ocular tissue exposure. Drug injection into the suprachoroidal space (SCS) allows for targeted delivery to chorioretinal tissues with high bioavailability in the posterior segment, as well as for inherent drug sequestration away from the anterior segment, which may lower the risk of AEs associated with anterior tissue exposure to steroids. A novel triamcinolone acetonide (TA) injectable suspension formulated for administration to the SCS, SCS-TA (Xipere®; Bausch + Lomb), received FDA approval in 2021 for the treatment of UME. It is administered via the SCS Microinjector® (Clearside Biomedical, Inc), a device specifically designed for SCS delivery of ocular therapeutics. This approval was based on results from the phase 3 PEACHTREE clinical trial (NCT02595398) that demonstrated the clinical efficacy-including significantly increased visual acuity and decreased central subfield thickness-and safety of SCS-TA in patients with UME. Results from this trial, as well as from its long-term observational extension (MAGNOLIA; NCT02952001) and an open-label safety study (AZALEA; NCT03097315), support the possibility that treatment with SCS-TA may address the burden of disease in patients with UME.
