Atom Bioscience Enrolling Patients in US as Part of a Global Phase 2b/3 Clinical Trial of a New Investigational Treatment for Chronic Gout

Atom Bioscience (Jiangsu Atom Bioscience and Pharmaceutical Co., Ltd.), a clinical stage biotechnology company developing new treatments for inflammatory and metabolic diseases, has begun enrolling patients in the US for in a Phase 2b/3 clinical trial of ABP-671, a novel investigational orally administered URAT1 inhibitor, for the treatment of chronic gout. Currently 36 sites have been identified in 17 states.

The multicenter, randomized, double-blind trial will enroll 580 patients worldwide. For locations of U.S. trial sites and contacts visit clinicaltrials.gov; (NCT05818085). Part 1 of the trial will evaluate the safety and efficacy of ABP-671 at different doses and regimens compared with either placebo or allopurinol, the current standard of care for management of gout in the U.S. Part 2 of the study will compare dosing regimens of ABP-671 selected from Part 1 with placebo in patients not enrolled in Part 1.

Gout is one of the most common types of inflammatory arthritis. It is caused by long-term hyperuricemia, an excessive concentration of serum uric acid (sUA) greater than 7 mg/dL (420 ?mol/L). Gout seriously affects people's quality of life and can increase the probability of sudden cardiac death. Existing drugs for treating chronic gout have poor efficacy and pose serious safety issues, such as leading to kidney failure, sudden cardiac death, or severe liver toxicity.
