Brief Summary:
A study to evaluate safety, tolerability, and pharmacokinetics of a single intravitreal injection of UBX1325 in patients diagnosed with diabetic macular edema (DME).

Condition or disease Intervention/treatment Phase
Diabetic Macular Edema Drug: UBX1325 Phase 1

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. UBX1325 will be administered intravitreally and all patients will be followed for approximately 6 months.

Drug: UBX1325
Investigational drug intravitreal injection

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. Plasma concentration of UBX1325 following a single intravitreal injection [ Time Frame: up to 24 hours post dose ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Nonproliferative diabetic retinopathy (DR) patients with DME.
  • Center-involved DME with central subfield thickness (CST) ≥350 μm on SD-OCT.
  • BCVA in the study eye (most affected) of 35 Early Treatment Diabetic Retinopathy Study (ETDRS) letters or worse of 6 months duration or longer prior to screening.
  • Patients who have the capacity to give informed consent and who are willing and able to comply with all study-related procedures and assessments.

Exclusion Criteria:

  • Any ocular/intraocular/periocular infection or inflammation in either eye.
  • History of vitreous hemorrhage in the study eye within 2 months prior to screening.
  • Any retinovascular disease or retinal degeneration other than DME in the study eye.
  • History of systemic and intraocular steroid use for 6 months prior to Day 1. The use of intravitreal nonbiodegradable steroid implants (ex. Iluvien®, Yutiq®, Retisert®) is prohibited.
  • Significant media opacities, including cataract, which might interfere with VA, assessment of toxicity, or fundus imaging.
  • Any uncontrolled medical condition that, in the opinion of the investigator, would preclude participation in this study.
