AstraZeneca said it had sold the rights for the treatments, named Seroquel and Seroquel XR, in the UK, China and other international markets, in a deal which will give it $260 million once the transaction closes, followed by future payments.

"The agreement with Luye Pharma is in line with AstraZeneca's strategy to focus on three main therapy areas while maximising the value from our legacy medicines like Seroquel," said Astra's executive vice president Mark Mallon in a statement on Tuesday.
