3SBio

3SBio is one of the largest and most established biotech drugmakers in China. Approximately 90 percent of its revenue is derived from four core drugs: TPIAO (rhTPO), Yisaipu (biosimilar of etanercept, a TNF-alpha inhibitor), rhEPO and Mandi (minoxidil). With the exception of minoxidil, an over-the-counter drug, the others are all older generation biologics. Most of the pipeline candidates are "me-too" drugs and in general are still at an early stage.
