Ardea Biosciences Presents Preclinical Data on RDEA119 Demonstrating Favorable Anti-Inflammatory Profile for Potential Use in Ulcerative Colitis

-- Phase 1 RDEA119 data expected in second half of 2008 -- -- Presentation at the Seventh Annual JMP Securities Research Conference on May 21st canceled; webcast of corporate update scheduled during Ardea's

Annual Stockholder Meeting on May 22nd at 9:30 a.m. PT --

SAN DIEGO, May 20 /PRNewswire-FirstCall/ -- Ardea Biosciences, Inc. (Nasdaq: RDEA) today announced that data was presented on the Company's lead mitogen-activated ERK kinase (MEK) inhibitor, RDEA119, demonstrating potent activity in mouse models of colitis. An oral presentation of the data was given at Digestive Disease Week (DDW) 2008 in San Diego, California.

The MEK1/2 pathway is important in cell cycle regulation in inflammatory bowel disease, including ulcerative colitis and Crohn's disease. RDEA119 was shown to reduce damage to colonic tissue in two different mouse models of colitis, murine trinitrobenzene sulfonic acid (TNBS) colitis model and murine dextran sulfate sodium (DSS) colitis model. The beneficial effect observed equaled or exceeded that of sulfasalazine (Azulfidine(R)), a therapy commonly used for acute and maintenance treatment of ulcerative colitis.

"Despite the existing treatments, there are still significant unmet medical needs for inflammatory bowel disease. Blocking the MEK1/2 pathway appears to be a promising strategy in the ongoing search for a new generation of therapies aimed to treat ulcerative colitis and Crohn's disease," said Barry D. Quart, PharmD, Ardea Biosciences' President and CEO. "These data further support the potential use of orally administered MEK inhibitors, such as RDEA119, for the treatment of inflammatory diseases."

To support the development of RDEA119 in inflammatory diseases, a Phase 1 study in normal healthy volunteers is ongoing in which the Company is evaluating the pharmacokinetics, safety and tolerability of RDEA119, as well as its ability to inhibit inflammatory cytokines. Preliminary Phase 1 data have demonstrated that RDEA119 has a long half-life and favorable pharmacokinetic properties, allowing for once daily oral dosing. In addition, RDEA119 is currently in a Phase 1 study in advanced cancer patients. The doses being evaluated in the Phase 1 study in advanced cancer patients have achieved systemic exposure consistent with active doses in animal models of human tumors, without drug-related toxicity.

The presentation is available on the Company website ( under the title "RDEA119, a Potent and Highly Selective MEK Inhibitor Ameliorates Murine Colitis."

About RDEA119

RDEA119, a non-ATP competitive, highly-selective MEK inhibitor for the treatment of inflammatory diseases and cancer, is the Company's lead compound from its MEK inhibitor research and development program. RDEA119 has shown potential as a potent inhibitor of MEK, which is believed to play an important role in inflammation, as well as cancer cell proliferation, apoptosis and metastasis. Preclinical and clinical results suggest that RDEA119 has favorable properties, including oral dosing, excellent selectivity and limited retention in the brain, which, in turn, may result in a reduced risk of central nervous system (CNS) side effects. The Company is also investigating a second generation MEK inhibitor, RDEA436, for potential use in inflammatory diseases and cancer. Preclinical data suggest that RDEA436 is a potent in vitro and in vivo inhibitor of MEK and may have favorable properties, such as low CNS penetration. In addition, RDEA436 has demonstrated a long half-life in a human micro-dose pharmacokinetic study, with the potential for once daily dosing in humans.

About Ardea Biosciences

Ardea Biosciences, Inc., of San Diego, California, is a biotechnology company focused on the discovery and development of small-molecule therapeutics for the treatment of HIV, cancer and inflammatory diseases, including gout. We have four drug candidates in clinical trials and others in preclinical development and discovery. Our most advanced development candidate is RDEA806, a non-nucleoside reverse transcriptase inhibitor (NNRTI), which is in a Phase 2a study for the treatment of HIV. We have evaluated our second-generation NNRTI for the treatment of HIV, RDEA427, in a human micro-dose pharmacokinetic study and have selected it as a development candidate. RDEA594, our lead development candidate for the treatment of gout, is in preclinical development and is believed to be an inhibitor of the URAT1 transporter in the kidney, which is responsible for regulation of uric acid levels. We are evaluating our lead MEK inhibitor, RDEA119, in a Phase 1 study in advanced cancer patients, as well as in a Phase 1 study in normal healthy volunteers as a precursor to trials in patients with inflammatory diseases. Lastly, we have evaluated our second-generation MEK inhibitor for the treatment of cancer and inflammatory diseases, RDEA436, in a human micro-dose pharmacokinetic study and have selected it as a development candidate.
