Ironwood Pharma Wins FDA Approval of Oral Gout Combo

Aug. 21, 2017

Ironwood Pharmaceuticals announced Duzallo was approved by the U.S. Food and Drug Administration as a once-daily oral treatment for hyperuricemia associated with gout in patients who have not achieved target serum uric acid (sUA) levels with a medically appropriate daily dose of allopurinol alone. Duzallo is not recommended for the treatment of asymptomatic hyperuricemia. Ironwood expects DUZALLO to be commercially available early in the fourth quarter of 2017.

The company says Duzallo is the first drug that combines the current standard of care for the treatment of hyperuricemia associated with gout, allopurinol, with the most recent FDA-approved treatment for this condition, lesinurad. This fixed-dose combination provides a dual mechanism of action in a single tablet that can address both underlying causes of hyperuricemia – overproduction and underexcretion of serum uric acid.

“The approval of Duzallo provides a new fixed-dose and dual-mechanism treatment option to help patients with uncontrolled gout achieve target serum uric acid levels. This represents an important and needed new option in the treatment of hyperuricemia,” said Michael A. Becker, M.D., professor emeritus of medicine, Department of Medicine, The University of Chicago, Chicago, IL.

The Duzallo NDA was submitted by Ardea Biosciences Inc. on behalf of Ironwood.
