Obexelimab (CD19) - Research Grade Biosimilar

Obexelimab (XmAb5871) is a first-in-class monoclonal antibody that targets CD19 with its variable domain and uses the XmAb immune inhibitory Fc domain to target FcγRIIb, a receptor that inhibits B cell function. Obexelimab is the first drug candidate to our knowledge that targets FcγRIIb inhibition.
