Esperion sues Daiichi Sankyo, demanding payment of $300M milestone for cardio drug
Esperion is suing its business partner Daiichi Sankyo, saying the Japanese drugmaker is improperly refusing to pay a $300 million milestone that the biotech company will be owed after reporting positive data from a large trial of its cardiovascular drug Nexletol.
The 2019 deal between the companies had Daiichi Sankyo pay $150 million upfront plus another $150 million after the first sales of the drug. But another major payout was tied to an outcomes study reported this month, known as CLEAR. Esperion, in its suit against Daiichi, argues that the drug’s more than 20% reduction of heart attack risk is enough to trigger a $300 million payout from Daiichi once it’s added to the drug’s label.
