Tasly Pharmaceutical (SHA:600535) agreed to terminate the deal to grant Arbor Pharmaceuticals exclusive rights in the U.S. for its Compound Danshen Dripping Pills, according to a Saturday filing on the Shanghai bourse.
The Chinese pharmaceutical company's shares slipped nearly 1% during Monday's morning trade.
Tasly granted the exclusive rights to Arbor in 2018.
The company said the parties have no dispute regarding the termination.
