About this study
Official title: A Multi-Center, Randomized, Parallel-Group, Phase 2, Masked, Three-Arm Trial 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 (OXEYE)
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.
Read the detailed description
Fifty-two (52) week phase 2 trial with two parts. Part A is an open-label, randomized, single-dose two treatment arm comparison of two dose levels of sustained-release suprachoroidal OXU-001 (DEXAspheres® administered using the Oxulumis® illuminated microcatheterization device) in subjects with Diabetic Macular Edema.
--- Part A was only partially recruited due a non-safety related sponsor decision to stop further recruitment after 3 randomized and treated subjects.
--- Part B is a randomized, masked, active comparator, single-dose, three treatment arm comparison of two dose levels of suprachoroidal OXU-001 and IVT Ozurdex® to evaluate the safety, tolerability, efficacy, and durability in subjects with Diabetic Macular Edema (DME).
--- Part B was not initiated due a non-safety related sponsor decision in Dec 2023.
--- In Part A, after a screening period, approximately 18 adult female or male subjects will be randomized in a 1:1 ratio to receive a single administration of one of two dose levels of OXU-001 (mid-dose or high-dose).
In Part B, after a screening period, approximately 110 adult female or male subjects will be randomized in a 2:2:1 ratio to receive a single administration of one of two dose levels of OXU-001 (Dose 1 or Dose 2) or Ozurdex®.
From Week 12, subjects will be assessed for the need for follow-on treatment. The follow-up period after treatment administration will be up to fifty-two (52) weeks.

- The trial was designed to include previously IVT anti-VEGF treated (in Part A and B) and treatment-naive (in Part B only) DME subjects. In Part A, approximately 18 subjects will be randomly assigned (ratio 1:1) to receive either a mid-dose or high-dose of suprachoroidal OXU-001. In Part B, approximately 110 subjects will be randomly assigned (ratio 2:2:1) to receive a single treatment of either suprachoroidal OXU-001 Dose 1, or Dose 2 or intravitreal Ozurdex® Note: Due to a non-safety related sponsor decision in Dec 2024 trial recruitment was stopped after only 3 subjects randomized and treated in Part A of the clinical trial. Part B was therefore not initiated.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing OXU-001, Semi-automated suprachoroidal illuminated microcatheter and Ozurdex® Ophthalmic Intravitreal Implant in people with Diabetic Macular Edema, run by Oxular Limited at 9 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frequency and Severity of Ocular and Systemic Treatment Emergent Adverse Events, Serious Adverse Events, and Adverse Events of Special Interest (time frame: Day 0 up to Week 52). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Sep 2025.
