Renowned Scientist and Drug Developer Joins UNITY s Mission to Extend

Succeeds Keith Leonard Who Will Continue as Chairman

SAN FRANCISCO, Calif., March 2, 2020 (GLOBE NEWSWIRE) UNITY Biotechnology today announced the appointment of Anirvan Ghosh,

Ph.D., as CEO and member of the Board of Directors, effective March 30, 2020. Dr. Ghosh joins UNITY from Biogen, where he served as Senior Vice President, Head of Research and Early Development. Current UNITY CEO, Keith Leonard, will be

leaving his operating role due to personal circumstances, but will continue as Chairman of the Board of Directors.

We are thrilled to attract a

world-class scientist and leader of Anirvan s stature to propel UNITY to the next level of achievement, said Keith Leonard. Augmenting our already strong executive team with Anirvan s insights and experience will ensure that

UNITY has the opportunity to realize its full potential. I look forward to continuing the journey and providing important continuity as I work with Anirvan in my capacity as Chairman.

UNITY President and co-founder, Nathaniel (Ned) E. David, Ph.D. added, I am really excited to work with Anirvan.

He brings an incredible breadth of experience to our mission to extend healthspan. I look forward to partnering with him to maximize the emerging promise of cellular senescense and to explore additional therapeutic applications beyond osteoarthritis

During his tenure at Biogen, Dr. Ghosh led a team of 350 scientists and clinicians responsible for preclinical and early

clinical development (Phase 1 and Phase 2 studies) in all of Biogen s therapeutic areas and led a marked expansion of Biogen s clinical pipeline. Between 2017 and 2020, ten programs advanced from

pre-clinical research into human clinical studies and several of these programs have demonstrated positive proof-of-concept

results in human studies and are currently in pivotal registration-enabling clinical trials. Dr. Ghosh was also involved in expanding Biogen s portfolio through key partnerships, including acquisition of early stage assets in

Alzheimer s disease, schizophrenia, ophthalmology, multi-asset platform collaborations in RNA regulation through anti-sense oligonucleotides, and small molecule approaches for targeted protein degradation and targeted splicing modulation.

There has been tremendous progress in our understanding of the cellular and molecular biology of aging, especially cellular senescence, in the past ten

years, and UNITY has been at the forefront of efforts to translate that understanding into the next generation of medicines to slow, halt or reverse the progression of age-related diseases, said

Dr. Ghosh. This is some of the most exciting science I have seen that could have a transformative impact on medicine, and I could not pass up this opportunity to lead UNITY into its next phase. I am deeply impressed with the portfolio

that UNITY has developed with the keen insight and long-term vision of the Board.

Prior to his time at Biogen, Dr. Ghosh served as founding CSO at

E-Scape Bio, and Global Head of Neuroscience Discovery and Biomarkers at Roche. In those roles, Dr. Ghosh led research and drug discovery for programs addressing neurodegenerative diseases as well as

neurodevelopmental and psychiatric disorders.

Prior to joining industry, Dr. Ghosh served as a professor of neuroscience at Johns Hopkins University

and the University of California, San Diego. Dr. Ghosh received a BS in Physics from the California Institute of Technology, a PhD in Neuroscience from Stanford University, and postdoctoral training at Harvard Medical School. The impact of his

scientific contributions is reflected in over 100 scientific publications in top-tier journals, including Science and Nature. He has been a recipient of numerous awards, and as a recognized

scientific leader, he has chaired leading scientific congresses including Gordon Research Conferences and Cold Spring Harbor Meetings.

UNITY is developing therapeutics to extend healthspan with an initial focus on cellular senescence. UNITY believes that the accumulation of senescent

cells is a fundamental mechanism of aging and a driver of many common age-related diseases. Cellular senescence is a natural biological state in which a cell permanently halts division. As senescent cells

accumulate with age, they begin secreting inflammatory factors, proteases, fibrotic factors, and growth factors, that disturb the tissue micro-environment. This collection of secreted proteins is referred to as the Senescence Associated Secretory

Phenotype, or SASP. UNITY is developing senolytic medicines to eliminate senescent cells and thereby stop the production of the SASP, which UNITY believes addresses a root cause of age-related diseases. By

stopping the production of the SASP at it source, UNITY believes senolytic medicines could slow, halt, or reverse diseases such as osteoarthritis and age-related eye diseases. More information is available at

Forward-Looking Statements

This press release contains forward-looking statements, including: statements related to UNITY s understanding of cellular senescence and the role

cellular senescence plays in age-related diseases; the potential for UNITY to develop medicines that eliminate senescent cells; the ability of UNITY to realize the potential of its programs; and the ability to

UNITY to have a transformative impact on medicine. These statements involve substantial known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially

different from the information expressed or implied by these forward-looking statements. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our

forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. The forward-looking statements in this press release represent our views as
