– Topline 12- and 24-week results expected in 2H 2020 –

SAN FRANCISCO, March 31, 2020 (GLOBE NEWSWIRE) — UNITY Biotechnology, Inc. (UNITY) [NASDAQ:UBX], a biotechnology company developing therapeutics to extend healthspan by slowing, halting or reversing diseases of aging, today announced updates related to UBX0101.

In February 2020, UNITY announced that it had dosed the first patients with moderate-to-severe osteoarthritis (OA) of the knee in a Phase 1b study to explore the safety, tolerability and initial efficacy of a single 8.0 mg dose or multiple doses (two 4.0 mg doses separated by one month) of UBX0101, an inhibitor of the p53/MDM2 protein-protein interaction. The study has now completed enrollment of 35 patients. Both 12- and 24-week data are currently expected in the second half of 2020.

Also in February 2020, UNITY announced completion of enrollment of a Phase 2 study of UBX0101 in patients with moderate-to-severe OA of the knee. This study, now fully enrolled with 183 patients, is randomized, double-blind, and placebo-controlled and will evaluate safety and efficacy of three doses of UBX0101 (0.5, 2.0 and 4.0 mg) administered via a single intra-articular injection. UNITY is focused on patient safety and has reviewed clinical protocol and operations in light of recent events and guidance from the Food and Drug Administration. The study currently remains on-track to report 12- and 24-week results in the second half of 2020.

“I am proud of our clinical team and investigators across the UBX0101 program as we continue to make great progress towards key data read-outs in the second half of the year,” said Jamie Dananberg, M.D. and chief medical officer of UNITY. “The COVID-19 pandemic has created extraordinary challenges for many clinical studies and we have been proactive in working with our investigators and sites to adapt to these challenges while consistently maintaining patient safety as a top priority.”

About UBX0101
UBX0101 is being evaluated for the treatment of musculoskeletal disease, with an initial focus on osteoarthritis (OA) of the knee. UBX0101 is a small molecule inhibitor of the p53/MDM2 protein-protein interaction. UBX0101 binds to MDM2, raising p53 levels which, in turn, we believe, causes the elimination of senescent cells. Initial results from a Phase 1 clinical trial in patients with moderate-to-severe OA of the knee were announced in June 2019. The study demonstrated that UBX0101 was well-tolerated. Dose-dependent improvement in several clinical measures, including pain and function, as well as modulation of multiple senescence-associated secretory phenotype (SASP) factors and disease-related biomarkers, were observed after a single dose of UBX0101.

About Osteoarthritis
Osteoarthritis (OA) is a degenerative disease that negatively impacts cartilage, subchondral bone and the synovial tissue lining the joint, causing pain and physical impairment. OA is a highly prevalent disease, symptomatically affecting as many as 10% to 15% of the world’s population over age 60, and results in a decline in quality of life. The most common joint affected by OA is the knee. Importantly, the current standard of care addresses only the symptoms of OA, which temporarily reduces joint inflammation and pain.

About UNITY
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.
