SAN DIEGO, April 25, 2011 /PRNewswire/ -- Ardea Biosciences, Inc. (Nasdaq: RDEA) today announced that additional data from its completed Phase 2b study (Study 203) evaluating lesinurad in combination with allopurinol in gout patients not adequately responding to allopurinol alone will be presented at the Annual European Congress of Rheumatology hosted by the European League Against Rheumatism (EULAR) on May 26, 2011 in London, UK.  The Company will also present additional data from a completed Phase 1b study evaluating the combination of lesinurad and febuxostat (Uloric®, Takeda Pharmaceutical Company Limited; Adenuric®, Ipsen and Menarini) in gout patients, as well as data from a completed preclinical study of lesinurad's effect on hyperuricemia caused by the commonly used diuretic, hydrochlorothiazide. Lesinurad is Ardea's lead product candidate for the treatment of hyperuricemia and gout.

About Hyperuricemia and Gout

Gout is a painful, debilitating and progressive disease caused by abnormally elevated levels of uric acid in the blood stream.  This leads to the deposition of painful, needle-like uric acid crystals in and around the connective tissue of the joints and in the kidneys, resulting in inflammation, the formation of disfiguring nodules, intermittent attacks of severe pain and kidney damage.  In addition, evidence suggests that the chronic elevation of uric acid associated with gout, known as hyperuricemia, may also have systemic consequences, including an increased risk for kidney dysfunction and cardiovascular disease.

In 2008, approximately 8.3 million patients in the U.S., 6.4 million patients in the European Union and 2.9 million patients in Japan were diagnosed with gout.  Gout is the most common form of inflammatory arthritis in men over the age of 40 and represents a significant unmet medical need with limited treatment options.

About Lesinurad

Our most advanced product candidate for the treatment of hyperuricemia and gout, lesinurad, previously called RDEA594, is an oral, once-daily inhibitor of URAT1, a transporter in the kidney that regulates uric acid excretion from the body.  Approximately 90% of gout patients are considered to be under-excretors of uric acid, and recent studies have shown that defects in renal transporters have been genetically linked to gout.  Consequently, increasing renal excretion of uric acid by moderating URAT1 transporter activity may provide the most physiologically appropriate treatment for gout.  In addition, because increasing the excretion of serum uric acid is additive to the effects of drugs that decrease the production of uric acid, such as allopurinol and febuxostat, lesinurad in combination with such drugs has the potential to treat the significant portion of the gout population that is not adequately treated with existing therapies.

Lesinurad has completed Phase 2 development as a single agent and in combination with the approved xanthine oxidase inhibitors, allopurinol and febuxostat.  Over 500 people have received lesinurad in Phase 1 and 2 clinical trials.
