About this study
Official title: A Phase 1, Open-Label, Single Ascending Dose Study to Assess the Safety and Tolerability of a Single Intravitreal Injection of UBX1325 in Patients With Diabetic Macular Edema or Neovascular Age-Related Macular Degeneration
A study to evaluate safety, tolerability, and pharmacokinetics of a single intravitreal injection of UBX1325 in patients diagnosed with diabetic macular edema (DME) or neovascular Age-Related Macular Degeneration.
Read the detailed description
This is a Phase 1, open-label, first-in-human (FIH), single-ascending dose (SAD) study consisting of approximately 4 cohorts. The total number of patients will be at least 3 per cohort plus 3 additional patients in the maximum tolerated dose (MTD) cohort in order to address the primary objective. Up to an additional 6 nAMD patients will be enrolled in the highest dose cohort. A single dose of UBX1325 will be administered intravitreally and all patients will be followed for approximately 6 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing UBX1325 in people with Diabetic Macular Edema and Neovascular Age-related Macular Degeneration, run by Unity Biotechnology, Inc. at 8 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 4 inclusion and 7 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 10 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Ocular and systemic safety and tolerability of a single intravitreal injection of UBX1325 evaluated by the incidence of dose limiting toxicities (DLTs) and treatment emergent adverse events (TEAEs) (time frame: 24 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04537884, which also lists 1 linked publication.
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 10 Mar 2022; AzTrials last refreshed its copy on 8 Nov 2026.
