April 18, 2024 updated by: Unity Biotechnology, Inc.

A Phase 2a, Prospective, Multicenter, Randomized, Double Masked, Sham-Controlled Study to Assess the Safety, Tolerability and Evidence of Activity of a Single Intravitreal Injection of UBX1325 in Patients With Diabetic Macular Edema

This study is intended to assess the exposure, safety, biological activity, and durability of UBX1325, a phosphate pro-drug, and its active parent molecule (UBX0601) following a single intravitreal (IVT) injection of UBX1325 in patients with diabetic macular edema (DME).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase 2a Proof-of-Concept (POC) study. The study will enroll approximately 62 patients randomized 1:1 into either the UBX1325 or sham study arms, in order to assess safety and tolerability as well as impact on visual function and retinal anatomy. Patients will be followed for 24 weeks for the primary outcome measure and for an additional 24 weeks (48 weeks total) for the secondary outcome measures.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients aged ≥ 18 years.
  • Diabetic retinopathy patients (nonproliferative (NPDR) and proliferative (PDR)) with DME (ETDRS-DRSS Score at 65C [or DR severity level of 8]or less severe as determined by a Central Reading Center), who had at least 2 anti-VEGF intravitreal (IVT) injections (one or more of the following agents: aflibercept, bevacizumab or ranibizumab) in the preceding 6 months prior to Day 1, with the last anti-VEGF given between 3 and 6 weeks prior to Day 1.
  • Center-involved DME with central subfield thickness (CST) ≥300 µm on SD-OCT at Screening
  • BCVA in the study eye (most affected) of 73 to 20 ETDRS letters (equivalent to 20/40 to 20/400 on the Snellen chart) at Screening and at Day 1.

Exclusion Criteria:

  • Concurrent disease in the study eye or structural damage, other than DME, that could compromise BCVA, prevent BCVA improvement, require medical or surgical intervention during the study period, confound interpretation of the results, or interfere with assessment of toxicity or color fundus photography (CFP) in the study eye.
  • Any ocular/intraocular/periocular infection or inflammation in either eye in the past 4 weeks prior to screening
  • History of vitreous hemorrhage in the study eye within 2 months prior to Screening
  • Any condition, including laboratory findings and findings in the medical history or in the pre-study assessments, that, in the opinion of the Investigator, constitutes a risk or contraindication for participation in the study or that could interfere with the study objectives, conduct, or evaluation or prevent the patient from fully participating in all aspects of the study
  • Significant media opacities, including cataract, which might interfere with VA, assessment of toxicity, or fundus imaging

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Systemic Safety and Tolerability of a Single IVT Injection of UBX1325.
Time Frame: 48 weeks
The systemic safety and tolerability is evaluated by incidence of Treatment Emergent Adverse Events (TEAEs) by System organ class Preferred Term.
48 weeks
Ocular Safety and Tolerability of a Single IVT Injection of UBX1325
Time Frame: Up to Week 12, 24 and 48 weeks

Ocular Safety is evaluated by incidence of Treatment Emergent Adverse Events (TEAEs).

Ocular TEAEs consisted of progression of disease or were related to the IVT injection component of the UBX1325 drug administration process
Up to Week 12, 24 and 48 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Best Corrected Visual Acuity (BCVA) From Baseline
Time Frame: Week 12, 24 and 48
Best Corrected Visual Acuity was assessed using the ETDRS chart starting at 4 meters
Week 12, 24 and 48
