Frequently asked questions about ulodesine

What is ulodesine used for?

Ulodesine is an investigational small molecule being developed for gout. It is studied as an add-on to allopurinol in patients with gout and hyperuricemia, including those with moderate renal insufficiency. Ulodesine is in Phase 2 clinical development and is not approved by the FDA.

How does ulodesine work?

Ulodesine is a small molecule that targets the purine metabolism pathway to lower serum uric acid levels. It is designed to be used in combination with allopurinol to reduce uric acid production in patients with gout and hyperuricemia.

Who is developing ulodesine?

Ulodesine is being developed by BioCryst Pharmaceuticals, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol BCRX. The company is conducting clinical trials to evaluate the safety and efficacy of ulodesine for the treatment of gout.

What phase is ulodesine in?

Ulodesine is in Phase 2 clinical development. Two Phase 2 trials have been completed, both evaluating the drug as an add-on to allopurinol in patients with gout and hyperuricemia. Ulodesine is investigational and has not received FDA approval.

What clinical trials has ulodesine been in?

Ulodesine has been studied in two completed Phase 2 trials. NCT01265264 enrolled 279 participants to evaluate the safety and efficacy of oral ulodesine added to allopurinol. NCT01407874 enrolled 20 participants with gout and moderate renal insufficiency to assess the uric acid effects of the combination.

Is ulodesine the same as BCX4208?

Ulodesine is also known by the code name BCX4208. It is a small molecule purine nucleoside phosphorylase inhibitor being developed by BioCryst Pharmaceuticals for the treatment of gout and hyperuricemia.
