FDA Fast Tracks Arthrosi's AR882 for Tophaceous Gout

SAN DIEGO, Aug. 19, 2024 -- Arthrosi Therapeutics, Inc., a biotechnology company in the late stages of development, has announced that the U.S. Food and Drug Administration (FDA) has awarded Fast Track Designation to their drug AR882. This drug is aimed at treating clinically visible tophi in gout patients. This recognition underscores the FDA's acknowledgment of the severe nature of gout with visible tophi and the potential of AR882 to address this significant medical need, according to Litain Yeh, Ph.D., Founder and CEO of Arthrosi Therapeutics. The company is currently in the midst of a pivotal Phase 3 clinical trial for AR882 and plans to collaborate closely with the FDA to expedite its development.

Fast Track Designation is a mechanism designed to speed up the development and review process for drugs that treat serious conditions where there is an unmet medical need.

Gout is a form of inflammatory arthritis affecting an estimated 13 million people in the United States. About 2 million of these individuals have visible tophi, which are hard deposits of uric acid that can appear in joints and soft tissue. Gout can severely impact a person's mobility, functionality, and overall quality of life. The condition arises from the buildup of uric acid crystals in the joints and soft tissues, leading to painful flare-ups and chronic symptoms. The kidneys play a crucial role in this process by filtering out uric acid from the body. In over 90% of gout patients, there is an underexcretion of uric acid, leading to elevated serum uric acid (sUA) levels and the formation of uric acid crystals. Monitoring and managing sUA levels are essential components of comprehensive gout treatment and prevention strategies.

Arthrosi Therapeutics, headquartered in San Diego, CA, is developing AR882, a next-generation URAT1 inhibitor that is designed to be highly potent and selective. The drug aims to reduce serum urate levels, as well as flares and tophi, in patients with gout. AR882 has shown promising efficacy and tolerability in nine clinical studies, including those involving patients with renal impairment and tophaceous gout. The company is currently advancing AR882 through its pivotal Phase 3 program and has received Fast Track Designation from the FDA for its potential to treat patients with clinically visible tophi.

Arthrosi Therapeutics continues to focus on the development of AR882 as a potentially best-in-class treatment for gout, committed to working closely with the FDA to bring this much-needed therapy to patients as quickly as possible.
