Oxulumis®, Suprachoroidal Drug Administration of Triesence® in Diabetic Macular Edema

Oxular Limited

Overview

The purpose of this clinical investigation is to evaluate the safety and tolerability of using the Oxulumis® microcatheterization device to administer Triesence® to the suprachoroidal space in participants with DME.

This 24-week, single-arm, single-dose clinical investigation will evaluate the safety and tolerability and explore the efficacy of the Oxulumis® microcatheterization device to administer Triesence® (triamcinolone acetonide suspension) 2.4 mg to the posterior suprachoroidal space in subjects with DME not responding to standard therapy. After a screening period, approximately 20 eligible subjects will receive a single dose of 2.4 mg Triesence® to the posterior suprachoroidal space. The follow-up period after treatment administration will be up to 24 weeks.

Inclusion Criteria: * Have been diagnosed with Type 1 or Type 2 diabetes mellitus. * Have Diabetic Macular Edema (DME) involving the center of the fovea in the study eye with a central retinal thickness (CRT), at the screening visit, of≥ 320 for males or ≥ 305 for females on Spectralis (Heidelberg) or ≥ 305 for males or ≥ 290 for females with Cirrus (Zeiss) by spectral domain optical coherence tomography (SD-OCT). * Have a best-corrected visual acuity (BCVA) in the study eye between 34 and 68 letters ETDRS at the screening visit. * Have shown limited response to previous IVT treatment with anti-vascular endothelial growth factor (VEGF) agents or local corticosteroid treatment (IVT, subtenon, topical) defined as less than 20% reduction of central subfield thickness (CST) with previous treatments. * Study eye suitable for suprachoroidal injection in the investigator's judgment in agreement with the medical monitor. Patients with ocular hypotony or structural abnormalities like choroidal coloboma or chorioretinal anastomosis, amongst others, are not eligible. Exclusion Criteria: * Presence of any other ocular condition in the study eye such that visual acuity may not improve from the resolution of macular edema (e.g., foveal atrophy, pigment abnormalities, or nonretinal causes). * Active proliferative diabetic retinopathy (PDR) or sequelae of PDR (including iris neovascularization, vitreous hemorrhage, or tractional retinal detachment) at screening in the study eye. * Pan-retinal photocoagulation (PRP) or macular laser photocoagulation in the study eye performed within sixteen (16) weeks before screening. * Prior IVT treatment with anti-VEGF in the study eye: last injection with ranibizumab or bevacizumab within four (4) weeks, aflibercept or brolucizumab within eight (8) weeks, faricimab within twelve (12) weeks before screening * Prior ocular treatment with steroids in the study eye: last injection (intra- or periocular) with triamcinolone acetonide within three (3) months, with dexamethasone implant (Ozurdex®) within six (6) months before screening. * Prior treatment with longer duration steroid implants (e.g., fluocinolone acetonide IVT implant, Iluvien®) is not allowed. * Prior treatment with suprachoroidal steroids is not allowed.

Outcomes

Primary Outcomes

Frequency of ocular adverse events, systemic adverse events, serious, and treatment-emergent non-serious adverse events

Treatment-emergent adverse events are defined as an event that emerges following administration of Triesence with the Oxulumis microcatheter administered at Visit 2 (Baseline, Day 0)

Time frame: 24 Weeks

Frequency of adverse device effects and frequency of serious adverse device effects

Adverse device effects and serious adverse device effects are defined as effects that emerge following the administration of the Oxulumis microcatheter at Visit 2 (Baseline, Day 0)

Time frame: 24 Weeks
