In the pipeline: Epratuzumab
Today's featured lymphoma treatment in the pipeline is the monoclonal antibody epratuzumab.
Name: Epratuzumab (marketed as LymphoCIDE)
Class: Anti-CD22 humanized monoclonal antibody
Type: Biological therapy
FDA to date: Orphan drug status; fast track designation (for lupus)
Manufacturer: Immunomedics Inc
Indications: Diffuse large b-cell lymphoma, follicular lymphoma, acute lymphblastic leukemia.
A few words: Epratuzumab targets cells expressing CD22 cell-surface receptors and is being investigated as part of combination chemotherapy, namely in an established regimen (ER-CHOP) against DLBCL. It has also been studied—with impressive results—as an agent of radioimmunotherapy (90Y-epratuzumab) in a small trial in patients with relapsed/refractory non-Hodgkin lymphoma and indolent lymphomas. The drug is also being explored as a treatment for autoimmune disorders such as lupus. Phase III trials are underway for all indications.
