Bispecific Antibodies - Roland E Kontermann - Häftad - Bokus

Trispecific antibodies that co-engage CD3 and a tumor antigen target have been designed and used to redirect T cells to attack and lyse targeted tumor cells. Examples include the BiTE and DART formats, which monovalently engage CD3 and a tumor antigen. 2019-02-01 · These trispecific molecules displayed broad neutralization activity and increased potency compared to the individual parental neutralizing antibodies (bNAbs) , , . Furthermore, Fab-based trispecific antibody formats have been evaluated. Targeting Eph (erythropoietin producing hepatoma) receptors with monoclonal antibodies is being explored as therapy for several types of cancer. To test whether simultaneous targeting of EphA2, EphA4, and EphB4 would be an effective approach to cancer therapy, we generated a recombinant trispecific antibody using the variable domain genes of anti-EphA2, anti-EphA4, and anti-EphB4 monoclonal Bispecific antibodies (BsAb) are promising therapeutic tools in tomorrow's medicine.

Fc modifications for altered Fc-receptor binding To examine the relationship between the incorporated Fc mutations with the antibodies’ PK, we measured concentra- tion-dependent binding Our founder and leading scientist have extensive expertise in the field of therapeutic antibody discovery, lead selection, engineering, humanization, and optimization. We look forward to developing novel therapeutic antibodies to target difficult-to-treat diseases via a combination of computer-aided design and traditional antibody discovery technologies.

Trispecific antibodies take to the clinic Sanofi and others are testing whether trispecific antibodies might have applications in cancer and infectious disease indications.

T Cell Mediated Cytotoxicity - Antibody Analytics. Here, we developed a trispecific antibody that interacts with CD38, CD3 and CD28 to enhance both T cell activation and tumor targeting. The engagement of both CD3 and CD28 affords efficient T cell A trispecific antibody is a flexible platform that might offer a way to deliver precise combinations of immunomodulatory signals (for example, a co-stimulatory signal and a checkpoint blocker) Here we demonstrate that the trispecific antibody is expressed at high levels by mammalian cells, monodispersed in solution, thermostable, capable of simultaneously binding the three receptors, and able to activate the three targets effectively as evidenced by receptor internalization and degradation both in vitro and in vivo. Polyspecific antibodies are promising class of anti-cancer agents which can be directed at multiple tumor antigens to eradicate tumor cells more precisely and effectively. They may overcome some of these limitations and have already changed treatment landscape for some malignancies such as B cell acute lymphoblastic leukemia.
