Bispecific monoclonal antibody

405:(formerly RG6013) is an IgG derivative containing H-chain heterodimerization motifs, which was combined with the common light chain approach to prevent L-chain mispairing issues. With a bivalent composition, emicizumab brings two protein antigens together into one complex. Factor IXa and Factor X in the coagulation cascade are the cognate antigens which are bound by RG6013. These two factors are brought together by coagulation factor VIIIa in a healthy individual, while patients with bleeding disorder hemophilia A do not have VIIIa. Current treatment of this disorder is to supplement the patients with FVIII to reduce bleeding complications. But FVIII can be recognized as a foreign protein in these patients due to the absence of this protein and thus an immune response will be generated against this protein. Besides, FVIII has a short half-life (less than 15 hours) and thus is cleared rapidly. However, the humanized BsAb has lower immunogenicity and long serum half-life compared with FVIII and thus provide a better treatment for hemophilia. 454:
total of eight more bispecific antibody drugs have since been approved by the US FDA: blinatumomab, emacizumab, amivantamab, tebentafusp, faricimab, teclistamab, mosunetuzumab, epcoritamab, glofitamab. Among the bsAb programs currently under development, the combination of CD3 and tumor surface targets are the most popular targets pairs. Other popular targets are CD3, HER2, PD-1, PD-L1, EGFR, CTLA-4, etc., which as well as immune targets of PD-1, PD-L1, BCMA, CD47, CTLA-4, LAG-3, 4 -1BB. Additionally, with the approval of the several new bsAb since 2022, and new mechanisms for improving efficacy like development of hetero-dimer bispecific molecules, several additional possibilities of target pairs have emerged.
92: 2331: 370:(Vectibix), both of which are directed against HER1. However, cancer cells can switch to a different pathway to escape the growth inhibition generated by blocking one signaling pathway. To improve the therapeutic efficacy, simultaneously interfering/blocking of two (or more) RTK signaling pathways, achieved through the mediation of BsAb to inactivate either the RTKs or their ligand, reduces the possibility of the escape mechanisms adopted by the tumor cells. 160: 254: 2530: 2542: 541: 58:. Naturally occurring antibodies typically only target one antigen. BsAbs can be manufactured in several structural formats. BsAbs can be designed to recruit and activate immune cells, to interfere with receptor signaling and inactivate signaling ligands, and to force association of protein complexes. BsAbs have been explored for 466:, which means the Fc region could cause detrimental downstream immune responses caused by cells that are activated by Fc receptors. The therapeutic use of BsAbs as a whole is still largely in development, with many clinical trials currently ongoing that are determining the efficacy and safety of BsAbs for treatment. 440:
lower than with ordinary antibodies. For non-IgG-like BsAbs, their smaller size allows them to reach antigens usually unavailable to conventional antibodies. In the case of Ebola vaccines, this method allows the antibody to target intracellular targets not usually accessible by traditional monoclonal

Bispecific antibodies have a wide variety of applications in diagnosis and therapy. BsAbs can be combined with HRPO, can be used in pre-targeting strategies, and can be used to provide better imaging for early detection in diagnosis. To treat cancer, BsAbs can target immune cells precisely, help and

Currently, nine bsAb drugs have been approved by the US FDA / EMA and over 180 are currently in clinical trials. The first bispecific antibody to gain regulatory approval, blinatumomab, targets CD19 on B cells and CD3 on T cells, leading to the activation of T cells and the destruction of B cells. A

reactive the immune cells, fine-tune the fate and function of immune cells, improve the tolerance of immune cells, and promote the return to immune homeostasis. BsAbs can also be applied to treat other diseases, including hemophilia A, diabetes, Alzeimer's disease, and ophthalmological diseases.

Additionally, targeting more than one molecule can be useful to circumvent the regulation of parallel pathways and avoid resistance to the treatment. Binding or blocking multiple targets in a pathway can be beneficial to stopping disease, as most conditions have complicated multifaceted effects
219:. The Bi-Nanobody platform forms multi-specific binding through the connection between the VH regions of two or more antibody molecules. The products that are designed based on this platform are small molecules and these small molecules have high stability and better tissue permeability 163:

The original concept of BsAbs was proposed by Nisonoff and his collaborators in the 1960s, including the first idea of antibody architecture and other findings. In 1975, the problem of producing pure antibodies was solved by the creation of

There are many formats of BsAbs, but the two main categories are IgG-like and non-IgG-like. The main types of manufacturing methods are quadromas, chemical conjugation, and genetic recombination, and each method results in a unique format.

However, the quadroma method relies on random chance to form usable BsAb, and can be inefficient. Another method for manufacturing IgG-like BsAb is called "knobs into holes," and relies on introducing a mutation for a large
