Launch Abbreviated: Teva Halts US Generic Sensipar Sales After Patent Deal With Amgen
In the course of a week, Teva received final ANDA approval for cinacalcet, launched its generic and reached a deal with Amgen to come off the market until mid-2021. The fast but short launch allowed Teva to take some sales away from Amgen without triggering entry of other ANDA sponsors who previously settled, Bernstein Senior Analyst Ronny Gal says.

A legal expert details how Piramal Healthcare could turn the tables and secure damages in the litigation pertaining to its generic version of Amgen's Sensipar, a case which saw multiple at-risk launches.
Cipla launched its generic version of Amgen’s Sensipar ‘at risk’ in March last year after suing the originator and Teva over an earlier agreement between the pair. The suit has now been settled, although claims against Teva remain standing.
