UBX1325 demonstrated vision gains that were comparable and statistically non-inferior to aflibercept at week 36 in a difficult-to-treat DME patient population
UBX1325 generally outperformed aflibercept in a pre-specified subgroup of patients entering the study with CST
Company to explore strategic alternatives to advance UBX1325, Tie2/anti-VEGF bispecific, and Tie2 agonistic antibody assets and reduce operational cash burn
May 05, 2025 -- UNITY Biotechnology, Inc. (“UNITY”) [NASDAQ: UBX], a biotechnology company developing therapeutics to slow, halt or reverse diseases of aging, today announced complete 36-week results from the Phase 2b ASPIRE clinical trial of intravitreal UBX1325 in patients with diabetic macular edema (DME) who had poor vision despite prior anti-VEGF treatment. The Company previously disclosed 24-week and interim 36-week results from its ASPIRE trial, demonstrating that UBX1325 was non-inferior to aflibercept at most time points through 36 weeks, except for the average of weeks 20 and 24, the primary endpoint.
Non-inferior visual gains in Best-Corrected Visual Acuity (BCVA) compared to leading anti-VEGF product
UBX1325 was statistically non-inferior to aflibercept at week 36
UBX1325 generally outperformed aflibercept in subjects who had moderately aggressive disease (central subfield thickness (CST)
Favorable safety and tolerability profile
UBX1325 continues to demonstrate a favorable safety and tolerability profile across multiple clinical studies to date
There have been no cases of intraocular inflammation, retinal artery occlusion, endophthalmitis or vasculitis across multiple studies
“UBX1325 has demonstrated the potential to provide a much-needed alternative treatment to anti-VEGF therapy through a completely novel mechanism of action,” said Anirvan Ghosh, Ph.D., chief executive officer of UNITY. “UBX1325’s demonstration of non-inferiority to aflibercept at 36 weeks and superior vision gains in the subgroup of patients with CST under 400 microns underscores its potential to provide a valuable treatment option to patients. We believe that further development of UBX1325 would benefit from the capabilities of a company with an existing ophthalmic franchise, and we are exploring partnerships so that this program can continue to be advanced as a potential new treatment. I am proud of the valuable contributions our team has made in advancing a new therapeutic concept for DME, as featured in our recently published article in NEJM Evidence.”
The Company will present full 36-week results from the ASPIRE study at the Association for Research in Vision and Ophthalmology (ARVO) 2025 Annual Meeting on Wednesday, May 7, 2025.
Corporate Update:
In conjunction with the full 36-week results, the Board of Directors has also approved a revised operating plan focused on evaluating strategic alternatives while reducing operational cash burn. As part of the operating plan, the Company will be implementing a reduction in force affecting all of its workforce, with certain consulting arrangements in place to close down the ASPIRE study. The Company intends to explore a full range of strategic alternatives, which may include, but are not limited to, the sale, license, monetization and/or divestiture of one or more of the Company’s assets and technologies (including UBX1325, the Tie2/aVEGF bispecific, and the Tie2 agonistic antibody), a strategic transaction, collaboration, partnership, merger, sale, or a winddown or dissolution of the Company. The Company’s Chief Executive Officer, Chief Financial Officer, and Chief Legal Officer will transition into consulting roles with the Company to support in evaluation of strategic alternatives and orderly transition of management roles. The Company may engage external advisors to support the evaluation of strategic alternatives. The Company's exploration of strategic alternatives may not result in the consummation of any transaction or the realization of any value for the Company or its shareholders.
UBX 1325 (BCL-xL inhibitor)
Clinical data from the Phase 2 BEHOLD Study and the Phase 2B ASPIRE study in patients with DME demonstrate improvement in visual acuity with UBX1325 treatment.
UBB 2048 (Tie2/aVEGF Bispecific)
Preclinical data indicate strong Tie2 pathway activation and inhibition of VEGF pathways, as well as efficacy in models of retinal disease, with clinical candidate molecule. The molecule targets a validated pathway for treating DME and wet age-related macular degeneration (AMD), with best-in-class potential.
UBX2050 (Tie2 agonistic antibody)
Preclinical data indicates strong Tie2 pathway activation with clinical candidate molecule with therapeutic rationale for diseases of vascular permeability, including chronic kidney disease, diabetic nephropathy, and vascular dementia.
Alpha-Klotho (biologic)
Global license agreement with Jocasta Neuroscience, Inc. for development and commercialization in neurological indications, with development milestones, approval milestones, and sales-based royalties.
Senescence and Aging biology IP portfolio:
Broad and foundational patent portfolio in senescence and other age-related biology for multiple indications including ophthalmology, neurological diseases, pulmonary diseases, kidney-related diseases, cardiac and vascular diseases.
ASPIRE is a multi-center, randomized, double-masked, active-controlled Phase 2b study designed to evaluate the safety and efficacy of UBX1325 in comparison to aflibercept in previously treated patients with active DME who are not achieving optimal benefit from standard of care. The study enrolled 52 subjects who were randomized 1:1 to receive either 10 μg UBX1325, or 2 mg of aflibercept control injections every eight weeks for six months after randomization. The primary efficacy endpoint is non-inferiority to aflibercept as assessed by mean change from baseline in Best Corrected Visual Acuity (BCVA) to the average of weeks 20 and 24. Additional information about ASPIRE (NCT06011798) can be found here.
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. UNITY’s goal with UBX1325 is to transformationally improve real-world outcomes for patients with retinal disease.
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.
