Clinical Trial Summary

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.

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.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 19
• Est. completion date: January 25, 2022
• Est. primary completion date: January 25, 2022
• Accepts healthy volunteers: No
• Gender: All
• Age group: 50 Years and older

Eligibility

Inclusion Criteria:

• nAMD patients who, in the opinion of the Investigator, are inadequately responding to or failed current treatment options.
• Active choroidal neovascularization (CNV) associated with age-related macular degeneration as evidenced on FA and SD-OCT at Day 1, including presence of intraretinal or subretinal fluid.
• BCVA in the study eye (most affected) of 70 Early Treatment Diabetic Retinopathy Study (ETDRS) letters or worse at screening and on Day 1.
• 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 in the past 4 weeks prior to screening.
• Subretinal hemorrhage with bleeding area =4 disc area in the study eye
• Concomitant therapy with anti-VEGF therapies (e.g., Avastin®, Lucentis®, or Eylea®) or previous use of these agents in the study eye within approximately 28 days of study enrollment
• Any retinovascular disease or retinal degeneration other than nAMD 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.
