SOUTH SAN FRANCISCO, Calif., April 23, 2025 (GLOBE NEWSWIRE) -- UNITY Biotechnology, Inc. (“UNITY”) [NASDAQ: UBX], a biotechnology company developing therapeutics to slow, halt or reverse diseases of aging, today announced that the peer-reviewed journal NEJM Evidence published results from the Phase 2 BEHOLD study of UBX1325 in patients with diabetic macular edema (DME). As reported in the article titled, “Safety and Efficacy of Senolytic UBX1325 in Diabetic Macular Edema,” the results suggested that the selective clearance of senescent cells in the retina provided disease-modifying and long-lasting improvements in vision in patients with DME, supporting the potential of UBX1325 as a novel modality for retinal diseases.
“By targeting senescent cells, we expect to remodel the retinal vasculature, which should lead to improvements in retinal function,” said Anirvan Ghosh, Ph.D., chief executive officer of UNITY and an author of the paper. “We see the impact of this approach in action in the BEHOLD study, in which patients experienced meaningful and sustained improvements in their visual acuity for 1 year after a single injection of UBX1325. By selectively targeting an underlying cause of inflammation and disease progression, senolytic therapies could provide a valuable future treatment option for DME patients.”
As previously disclosed and presented at the Association for Research in Vision and Ophthalmology (ARVO) 2024 Annual Meeting, a single injection of the senolytic candidate UBX1325 led to a statistically significant and clinically meaningful improvement in vision with extended durability through 48 weeks in patients with advanced DME. UNITY is currently conducting a Phase 2b ASPIRE study to evaluate multiple doses of UBX1325 in a head-to-head comparison to aflibercept. Topline 24-week and 36-week data was disclosed on March 24, 2025 and full 36-week data is expected in the second quarter of 2025.
About the BEHOLD Study
The proof-of-concept Phase 2 BEHOLD study is a multi-center, randomized, double-masked, sham-controlled study designed to evaluate the safety, tolerability, efficacy and durability of a single 10 mcg dose of UBX1325 in patients with DME. The study enrolled 65 patients who, despite being on anti-VEGF treatment for at least 6 months, displayed persistent visual acuity deficits (73 ETDRS letters, approximately 20/40, or worse) and residual retinal fluid (CST ≥300 microns). At baseline, patients in the study had an average visual acuity of 61.4 ETDRS letters and a CST of approximately 439.6 microns. In the 6 months prior to study enrollment, patients received an average of 4 anti-VEGF injections, with the last anti-VEGF injection occurring 3-6 weeks prior to randomization. Fifty patients completed the 48-week study extension. More information about the study is available here (NEJM Evidence) and here.
About UBX1325
UBX1325 is an investigational compound being studied in retinal diseases, including DME, and is not approved for any use in any country. UBX1325 is a potent small molecule inhibitor of BCL-xL, a member of the BCL-2 family of apoptosis regulating proteins. UBX1325 is designed to inhibit the function of proteins that senescent cells rely on for survival. The Phase 2 BEHOLD study in patients with DME demonstrated that a single injection of UBX1325 resulted in a statistically significant and clinically meaningful improvement in mean BCVA through 48 weeks compared to sham treatment. In preclinical studies, UNITY has demonstrated that targeting BCL-xL with UBX1325 preferentially eliminated senescent cells from diseased tissue while sparing cells in healthy tissue. Multiple doses of UBX1325 are currently being evaluated in the ASPIRE Phase 2b study for people with DME who are not achieving optimal benefit from anti-VEGF drugs (NCT06011798). UNITY’s goal with UBX1325 is to transformationally improve real-world outcomes for patients with retinal disease.
About UNITY
UNITY is developing a new class of therapeutics to slow, halt, or reverse diseases of aging. UNITY’s current focus is on creating medicines to selectively eliminate or modulate senescent cells and thereby provide transformative benefit in age-related ophthalmologic and neurologic diseases.
