Blinatumomab linking a T cell to a malignant B cell.. Blinatumomab is a bispecific T-cell engager (BiTE). [7] It enables a patient's T cells to recognize malignant B cells. A molecule of blinatumomab combines two binding sites: a CD3 site for T cells and a CD19 site for the target B cells.
Inotuzumab ozogamicin is used to treat relapsed or refractory B-cell precursor acute lymphoblastic leukemia. [4] [5]In March 2024, the FDA approved inotuzumab ozogamicin for the treatment of children aged one year and older with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukemia.

An anti-CD22 immunotoxin is a monoclonal antibody targeting CD22 linked to a cytotoxic agent. As of August 2009, it was studied in the treatment of some types of B-cell cancer. It binds to CD22, a receptor protein on the surface of normal B cells and B-cell tumors , and, upon internalization, kills the cells, acting as immunotoxin .
The treatment is a type of metabolic therapy that has no evidence of efficacy. [47] Hoxsey therapy – a treatment consisting of a caustic herbal paste for external cancers or a herbal mixture for "internal" cancers, combined with laxatives, douches, vitamin supplements and dietary changes.
