Durect Corp. (DRRX) on Monday said Novartis AG's (NVS) Sandoz unit had ended a deal to develop and commercialize Durect's Posimir non-opioid postoperative painkiller and is disputing its obligation to pay a termination fee.

The Cupertino, Calif., biopharmaceutical company agreed in May 2017 to license Posimir to Sandoz for a $20 million upfront fee, up to $43 million in development and regulatory milestone payments, and up to $230 million in sales-based milestones.

The companies amended the deal a year later, reducing the potential development and regulatory milestone payments to $30 million, after a phase 3 study of Posimir missed its primary endpoint.

Durect on Monday said Sandoz is returning its U.S. development and commercialization rights to Posimir as part of a refocusing of its resources but is disputing its obligation to pay a termination fee. Durect said it has initiated a formal dispute resolution process related to the fee, the amount of which hasn't been publicly disclosed.

The company said it will evaluate and consider potential next steps for Posimir.

Shares of Durect fell 12.6% to 57 cents in Monday afternoon trading.
