UNITY Biotechnology, Inc. Reports Fourth Quarter and Full Year 2024 Financial Results

and Business Updates

SOUTH SAN FRANCISCO, Calif., March 7, 2025 (GLOBE NEWSWIRE) -- UNITY Biotechnology, Inc. (UNITY) [NASDAQ:UBX], a biotechnology company developing therapeutics to slow, halt, or reverse diseases of aging, today reported financial results for the fourth quarter and full year ended December 31, 2024.

“We expect to receive 24-week topline data from our Phase 2b ASPIRE study in diabetic macular edema (DME) in this quarter,” said Anirvan Ghosh, Ph.D., chief executive officer of UNITY. “DME remains a significant unmet need, and we believe UBX1325 (foselutoclax) has the potential to provide a differentiated treatment option for patients who continue to experience vision loss despite current standard-of-care therapies. With its novel mechanism of action and durable therapeutic profile, UBX1325 could offer meaningful advantages over existing anti-VEGF treatments. The 24-week data as well as the 36-week data will be instrumental in shaping our plans for a potential pivotal trial and advancing our program.”

UBX1325 (foselutoclax) is designed as a novel and durable therapeutic option in DME that acts via a senolytic mechanism of action, with the potential to address shortcomings of the current standard of care, such as high treatment burden and sub-optimal response to treatment.

UNITY anticipates receiving topline 24-week primary endpoint data in the first quarter of 2025 and 36-week data in the second quarter of 2025. The Phase 2b ASPIRE study in DME is a multi-center, randomized, double-masked, active-controlled study designed to evaluate the safety and efficacy of UBX1325 in a head-to-head comparison to aflibercept.

Fourth Quarter and Full Year Financial Results

Cash, cash equivalents and marketable securities totaled $23.2 million as of December 31, 2024 compared with $43.2 million as of December 31, 2023. UNITY believes that current cash, cash equivalents and marketable securities are sufficient to fund operations into the fourth quarter of 2025.

Net loss for the twelve months ended December 31, 2024 was $26.0 million compared to $39.9 million for the twelve months ended December 31, 2023. Cash used in operations during the year ended December 31, 2024 was $20.9 million compared to $37.1 million for the twelve months ended December 31, 2023. Total net loss for the fourth quarter of 2024 was $8.4 million compared to $4.3 million for the fourth quarter of 2023. Cash used in operations during the fourth quarter of 2024 was $5.9 million compared to $6.7 million for the fourth quarter of 2023.

Research and development expenses decreased by $7.1 million, to $13.0 million for the year ended December 31, 2024 from $20.1 million for the year ended December 31, 2023. The decrease was primarily due to decreases of $3.5 million in personnel costs due to our reduced headcount and the reduction in force, $2.7 million in direct research and development expenses mainly due to the completion of our UBX1325 BEHOLD and ENVISION studies, and $0.9 million in facilities-related costs primarily due to the sublease of our East Grand facility. Research and development expenses decreased by $0.2 million, to $3.1 million for the fourth quarter of 2024 from $3.3 million for the fourth quarter of 2023. The decrease was due to decreases of $0.5 million in

personnel-related costs due to reduced headcount, partially offset by a increase of $0.3 million in direct research and development expenses primarily due to the ongoing UBX1325 ASPIRE study.

General and administrative expenses decreased by $3.5 million, to $15.5 million for the year ended December 31, 2024 from $19.0 million for the year ended December 31, 2023. The decrease was primarily due to decreases of $2.5 million in personnel costs due to our reduced headcount and reduction in force, $0.4 million in professional fees, and $0.6 million in facilities-related costs primarily due to the sublease of our East Grand facility. General and administrative expenses decreased by $0.1 million, to $4.3 million for the fourth quarter of 2024 from $4.4 million for the fourth quarter of 2023. The decrease was primarily due to decreases of $0.2 million in personnel-related costs due to lower headcount, partially offset by increases of $0.1 million in professional and consulting fees.
