Mabwell (Shanghai) Bioscience (HKG:2493, SHA:688062) said Chinese regulators expanded denosumab's approval to include new indications, according to a Wednesday filing with the Hong Kong bourse.
The firm's Hong Kong shares gained nearly 4% in morning trade Thursday.
Denosumab, also known as maiweijian and 9MW0321, will now be available to treat bone metastases from solid tumors and to delay or reduce the risk of skeletal-related events in patients with multiple myeloma.
The medicine, a biosimilar version of Xgeva, was previously approved in China to treat giant cell tumor of the bone.
