Unity Biotechnology announces extension of Phase 2b ASPIRE study of UBX1325

UNITY Biotechnology announced that the ongoing Phase 2b ASPIRE study of UBX1325 has been extended from 24 to 36 weeks to assess potentially greater durability compared to aflibercept. In addition, the study is being upsized from 40 to 50 patients to increase the statistical power. The ASPIRE study is designed to evaluate the safety, efficacy, and long-term durability of UBX1325 as a monotherapy compared head-to-head to aflibercept in patients with diabetic macular edema, DME. “We previously demonstrated significant improvement in vision with extended durability in patients treated with UBX1325 in the BEHOLD proof-of-concept study and look forward to extending those findings in the current ASPIRE study,” said Anirvan Ghosh, Ph.D., chief executive officer of UNITY. “As the only treatment candidate in clinical development for DME that targets senescent cells, UBX1325 leverages a novel mechanism of action that could provide sustained improvements in visual acuity and lessen the treatment burden compared to current standard of care. We see UBX1325 as an emerging, potentially paradigm-shifting therapeutic approach in DME.” As a result of extending the study, UNITY expects to disclose topline results from the ASPIRE study in two data readouts: 24-week primary endpoint data in the first quarter of 2025, and 36-week long-term extension data in the second quarter of 2025. The Company continues to believe that current cash, cash equivalents and marketable securities are sufficient to fund operations into the third quarter of 2025.
