Latest patent settlement keeps Linzess generic at bay till 2030

4 May 2018

Under the terms of a settlement, drugmakers Ironwood Pharmaceuticals (Nasdaq: IRWD) and Allergan (NYSE: AGN) have granted Aurobindo Pharma (ARBN: BO) a license to market a generic version of Linzess (linaclotide) in the USA – but not until August 5, 2030.

The firms launched patent litigation in response to the Indian generics maker’s abbreviated new drug application (ANDA) seeking approval to market a copy of Linzess prior to the expiration of the companies’ applicable patents.

This is the second patent infringement settlement that Ironwood and Allergan have reached with respect to Linzess, having settled with wholly-owned subsidiaries of India’s Sun Pharmaceutical Industries (BSE: 524715) in January. That agreement stopped the generic from being launched in the USA before February 1, 2031.
