技术背景

Target Background

Mosunetuzumab is an innovative bispecific antibody that has a structure that resembles a natural human antibody, with two 'Fab' regions. However, it differs from naturally-occurring antibodies as one 'Fab' region targets CD20 and the other targets CD3. By recognizing and binding to these two different targets, Mosunetuzumab is able to redirect the cytotoxic activity of T-cells towards cancerous B-cells. This unique mechanism of action holds great potential for enhancing the effectiveness of cancer treatment.
Cevostamab (BFCR4350A) is an innovative bispecific antibody, designed to engage T-cells and myeloma cells by targeting FcRH5 and CD3 receptors, respectively. Cevostamab possesses a unique structure with two 'Fab' regions, with one specifically targeting FcRH5 and the other targeting CD3. This dual targeting mechanism activates the patient's own T-cells and redirects them to eliminate myeloma cells expressing FcRH5 by releasing cytotoxic proteins.
