Unity Biotechnology, Inc. (NASDAQ:UBX) is a clinical-stage biotechnology company at the forefront of developing innovative therapies to address the underlying causes of age-related diseases. With a relentless focus on senescence biology, Unity Biotechnology is paving the way for a new era in the treatment of debilitating conditions that afflict millions worldwide.
Business Overview and History
Unity Biotechnology, Inc. was founded in 2009 and is headquartered in South San Francisco, California. The company’s core mission is to leverage its proprietary senolytic platform to create therapies that can selectively eliminate or modulate senescent cells – those that have ceased to divide and are a major contributor to the decline of tissue function with age.
In July 2020, Unity filed an Investigational New Drug (IND) application to commence a Phase 1 clinical study of its lead drug candidate, UBX1325, in patients with diabetic macular edema (DME) and neovascular age-related macular degeneration (nAMD). The Phase 1 study, an open-label, single ascending dose trial, began in October 2020 and evaluated doses from 0.5 to 10 μg administered as a single intravitreal injection. The results of this study, announced in 2021, demonstrated acceptable safety and tolerability without any dose-limiting toxicities and mean improvement in best corrected visual acuity.
Following the success of the Phase 1 study, Unity initiated its Phase 2 BEHOLD study of UBX1325 in patients with DME in May 2021. This was a multi-center, randomized, double-masked, sham-controlled study designed to evaluate the safety, tolerability, efficacy and durability of a single 10 μg dose of UBX1325. In August 2022, Unity announced positive 12- and 18-week data from the BEHOLD study, including that a single injection of UBX1325 led to a progressive, statistically significant, and clinically meaningful improvement in mean best-corrected visual acuity compared to sham treatment. The company subsequently announced positive 24-week and 48-week data from the BEHOLD study in November 2022 and April 2023, respectively.
To optimize its resources and focus on its ongoing clinical programs, Unity implemented restructuring efforts in February 2022 and May 2023. These actions included reductions in headcount to extend the company’s runway and enable it to achieve multiple key clinical data readouts for UBX1325. The May 2023 restructuring resulted in a headcount reduction of approximately 29%.
Financial Performance and Liquidity
Unity Biotechnology’s financial performance has been marked by consistent investment in research and development to advance its innovative pipeline. As a clinical-stage company, the company has not yet generated any product revenue, with its primary source of funding coming from equity and debt financing.
For the fiscal year ended December 31, 2023, Unity Biotechnology reported a net loss of $39.86 million, compared to a net loss of $44.47 million in the prior year. The company’s research and development expenses for the year amounted to $20.10 million, while general and administrative expenses were $18.97 million. Operating cash flow (OCF) for the year was -$37,088,000, and free cash flow (FCF) was -$37,099,000.
For the quarter ended September 30, 2024, Unity Biotechnology reported a net loss of $6.48 million, compared to a net loss of $14.78 million for the same period in the prior year. The decrease in net loss was primarily due to reductions in research and development expenses and general and administrative expenses. Operating cash flow for the quarter was -$5,193,000, and free cash flow was also -$5,193,000. The decrease in net income, OCF, and FCF compared to the prior year quarter was primarily due to decreased direct research and development expenses as the company completed its Phase 2 BEHOLD and ENVISION studies, lower personnel costs from reduced headcount, and decreased operating costs from reduced fixed asset depreciation and reduced office space.
As of September 30, 2024, Unity Biotechnology had cash, cash equivalents, and marketable securities of $29.00 million, which the company believes will fund its planned operating expenses into the third quarter of 2025. The company’s current ratio and quick ratio, measures of its short-term liquidity, both stood at 3.45 as of the same date, indicating a strong ability to meet its near-term obligations. Unity Biotechnology has no outstanding debt, resulting in a debt-to-equity ratio of 0.
It’s important to note that Unity Biotechnology has faced certain financial challenges in the past, including a material weakness identified in its internal control over financial reporting in 2023. The company has implemented remediation measures to address this issue and is committed to maintaining robust financial controls going forward.
Unity Biotechnology operates solely in the United States and does not have any international operations.
Clinical Pipeline and Development Milestones
Unity Biotechnology’s clinical pipeline is centered around its lead candidate, UBX1325, a novel small molecule that targets the Bcl-xL protein to selectively eliminate senescent cells. The company’s focus on ophthalmological disorders, particularly DME and nAMD, reflects its strategic prioritization of areas with significant unmet medical needs and the potential for transformative impact.
The ongoing Phase 2b ASPIRE study, which aims to enroll 50 patients with active DME, is a crucial milestone for Unity Biotechnology. The study has been expanded from its original 40 patients and extended from 24 to 36 weeks to better assess the efficacy and durability of UBX1325 compared to aflibercept, the current standard of care. Topline 24-week primary endpoint data from the ASPIRE study is expected in the first quarter of 2025, followed by 36-week long-term extension data in the second quarter of the same year.
In addition to the ASPIRE study, Unity Biotechnology has also advanced UBX1325 in the treatment of nAMD. The company’s Phase 2 ENVISION study, which enrolled patients with active nAMD, has yielded promising results, with UBX1325 demonstrating the ability to maintain visual acuity through 24 weeks, with 52% of patients not requiring anti-VEGF rescue treatments over this period.
The positive data from Unity Biotechnology’s clinical trials have garnered significant attention within the ophthalmology community. In 2024, the company presented its findings at the prestigious Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting, further validating the potential of its senolytic approach to address debilitating eye diseases.
