China's medical products administrator approved ImmuneOnco Biopharmaceuticals' (HKG:1541) phase 2 trial for its IMM0306 drug for lupus nephritis, according to a Monday filing with the Hong Kong Exchange.
Lupus nephritis is an autoimmune condition which lets the immune system attack its own organs.
The drug binds the cluster of differentiation 47 to CD20, which helps eliminate malignant B cells that help tumor growth, the filing said.
