Hatch-Waxman Tracker Updated

The Hatch-Waxman Tracker has been updated with two new cases:  Adams Respiratory Therapeutics v. Mutual Pharmaceuticals and United Research Laboratories (D. N.J.); and Savient Pharmaceuticals v. Barr Laboratories (D. N.J.).

Adams recently sued Mutual for infringement of U.S. Patent No. 6,372,252, which relates to Adams' oral solid, extended-release guaifenesin products, Mucinex and Humibid.  According to Adams' press release announcing the lawsuit, the two drugs are the only FDA-approved extended-release expectorant products that provide 12-hour relief from chest congestion in one tablet.

Savient sued Barr for infringement of five U.S. patents relating to various methods of using Oxandrin (oxandrolone tablets).  According to Savient's press release, Oxandrin is an oral anabolic agent indicated as adjunctive therapy to promote weight gain after weight loss following extensive surgery, chronic infection, or severe trauma.
