Chinese contract research organization WuXi AppTec Co. Ltd. is gearing up to launch an IPO for its pharmaceutical business on the Shanghai Stock Exchange, Security Times reported.

In January, the company filed for an IPO of its biologics arm on the Hong Kong Stock Exchange.

Wuxi AppTec was previously listed on the NYSE as Wuxi Pharmatech, but withdrew its listing in December 2015.

The company said March 23 that it enlisted Huatai United Securities as consultant for the SSE offering.
