What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Subjects Improved >=2 Steps From Baseline in the DRSS Score at Week 36

    The DRSS used to describe overall retinopathy severity as well as the change in severity over time in the study eye. Severity ranges from level 10 (diabetic retinopathy absent) to level 85 (advanced proliferative diabetic retinopathy (PDR): posterior fundus obscured, or center of macula detached). Here, DRSS describes severity level 47 (moderately severe NPDR) and level 53 (severe NPDR) at Week 36 from baseline.

    Measured: Baseline (Day 1) and Week 36

Secondary outcomes (12)
  1. Percentage of Subjects Improved >=2 Steps From Baseline in the DRSS Score at Week 24 and Week 48

    The DRSS used to describe overall retinopathy severity as well as the change in severity over time in the study eye. Severity ranges from level 10 (diabetic retinopathy absent) to level 85 (advanced proliferative diabetic retinopathy (PDR): posterior fundus obscured, or center of macula detached). Here, DRSS describes severity levels 47 (moderately severe NPDR) and 53 (severe NPDR) at Weeks 24 and 48 from baseline.

    Measured: Baseline (Day 1), Week 24, and Week 48

  2. Percentage of Subjects Improved >=2 Steps and >=3 Steps From Baseline in DRSS Score at Weeks 24, 36 and 48

    The DRSS used to describe overall retinopathy severity as well as the change in severity over time in the study eye. Severity ranges from level 10 (diabetic retinopathy absent) to level 85 (advanced PDR: posterior fundus obscured, or center of macula detached). Here, DRSS describes severity level 47 (moderately severe NPDR) and level 53 (severe NPDR) at Weeks 24, 36 and 48 from baseline.

    Measured: Baseline (Day 1) and Weeks 24, 36 and 48

  3. Percentage of Subjects Worsened >=2 Steps and >=3 Steps From Baseline in DRSS Score at Weeks 24, 36 and 48

    The DRSS used to describe overall retinopathy severity as well as the change in severity over time in the study eye. Severity ranges from level 10 (diabetic retinopathy absent) to level 85 (advanced PDR: posterior fundus obscured, or center of macula detached). Here, DRSS describes severity level 47 (moderately severe NPDR) and level 53 (severe NPDR) at Weeks 24, 36 and 48 from baseline.

    Measured: Baseline (Day 1) and Weeks 24, 36 and 48

  4. Percentage of Subjects Who Developed a Vision-Threatening Complication Due to Diabetic Retinopathy at Weeks 24, 36 and 48

    The vision threatening complications in the study eye due to diabetic retinopathy were indicated by the presence of "Vitreous hemorrhage" or the presence of "Tractional retinal detachment" reported on the Ocular Examination - Dilated Ophthalmoscopy CRF (PDR events), and "Neovascularization for the Iris" answered as "Yes" or "Neovascularization for the Angle" answered as "Yes" per the Ocular Examination - Slit Lamp Biomicroscopy CRF (anterior segment neovascularization (ASNV) events).

    Measured: Weeks 24, 36 and 48

  5. Percentage of Subjects Who Developed Center Involved-Diabetic Macular Edema (CI-DME) at Weeks 24, 36 and 48

    The CI-DME in the study eye occurred when a treatment emergent adverse event (TEAE) with a mapped preferred term of 'Cystoid macular oedema', 'Diabetic retinal oedema', or 'Macular oedema' occurred in the study eye, in combination with the temporally closest centrally read custom algorithm CST measurement being greater than or equal to 320 microns.

    Measured: Weeks 24, 36 and 48

  6. Time to Develop Any Neovascular Vision Threatening Complication (PDR/ASNV) at Weeks 24, 36 and 48

    Time to develop any PDR/ASNV was computed as the date of the first development of PDR/ASNV in the study eye minus the date of study treatment administration plus 1 day, divided by 7 days per week.

    Measured: Weeks 24, 36 and 48

  7. Time to Develop CI-DME Through Weeks 24, 36 and 48

    The occurrence of a CI-DME event in the study eye was identified via examination of centrally read custom algorithm CST data and adverse events.

    Measured: Weeks 24, 36 and 48

  8. Percentage of Subjects Who Received Anti-Vascular Endothelial Growth Factor (VEGF) or Additional Standard of Care Intervention Due to Ocular Diabetic Complications at Weeks 24, 36 and 48

    Percentage of subjects who received anti-VEGF or additional standard of care intervention due to ocular diabetic complications in the study eye are reported. Anti-VEGF use was identified in reported concomitant medication data.

    Measured: Weeks 24, 36 and 48

  9. Percentage of Subjects Who Received PRP at Weeks 24, 36 and 48

    Percentage of subjects who received PRP in the study eye, inclusive of subjects undergoing vitrectomy with endo-laser are reported.

    Measured: Weeks 24, 36 and 48

  10. Area Under the Curve (AUC) for Change From Baseline in BCVA at Weeks 24, 36 and 48

    The AUC for change from baseline in BCVA in the study eye were summarized. The AUC through each time point of interest was computed using the trapezoidal rule normalized to months, with a final unit of letters.

    Measured: Weeks 24, 36 and 48

  11. Plasma Concentration of EYP-1901 and X-297 at Weeks 24, 36 and 48

    Blood samples were collected at the specific visits for the Pharmacokinetic (PK) analysis of EYP-1901 and its main metabolite concentrations.

    Measured: Weeks 24, 36 and 48

  12. Number of Subjects With Ocular and Non-Ocular TEAEs and Serious TEAEs up to Week 48

    An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a patient or clinical investigation subject administered an investigational or marketed (medicinal) product and that does not necessarily have a causal relationship with the product. A serious AE is any AE that results in one of the following outcomes: death; life-threatening; requires in-patient hospitalization; results in a persistent or significant disability/incapacity; congenital anomaly/birth defect; other important medical event. The TEAEs are AEs that occur after the first dose of study treatment administration.

    Measured: TEAEs were collected from the study drug administration (Day 1) up to end of the study, approximately 48 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing EYP-1901 in people with Nonproliferative Diabetic Retinopathy, run by EyePoint Pharmaceuticals, Inc. at 36 sites in United States.

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 2 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 15 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 36 sites in United States. 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. Some participants in this study may receive a placebo. 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 28 Jul 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?

Percentage of Subjects Improved >=2 Steps From Baseline in the DRSS Score at Week 36 (time frame: Baseline (Day 1) and Week 36). 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 15 Aug 2025.
