“Currently Chinese Pharmaceutical Companies Are Dominating Global Tetraspecific Antibodies Clinical Trials Landscape”
Traditional treatment, like chemotherapy, were backbone for the management of cancer diseases for many years, but in contemporary years, the advent of new generation therapeutic methods, comprising monoclonal along with bispecific antibodies have arose as market frontrunners. Notwithstanding, monoclonal antibodies have demonstrated colossal triumph in the realm of immunotherapy, there comes a number of disadvantages such as their ability to target one type of antigens as well as expansion of increased resistance to them urges the need to develop more therapies that will target more than one antigen or foreign foe inside the person’s body. Therefore, scientists have introduced another novel antibody format - tetraspecific antibody - that targets four antigens at the same time, in order to maximize the therapeutic index of treatment regimen.
Clinically, the concept of tetraspecific antibodies begun in the late 1960s when Nosonoff together with his colleagues introduced the hypothesis of constructing multispecific antibodies by combining fragments from monovalent antibodies. Following that, tetraspecific antibodies come into picture which uses the approach of targeting four antigens at the same time for the treatment of cancer.

Presently, the panorama of tetraspecific antibody is endorsing a transformative shift towards targeted medicine as evident from rising preclinical as well as clinical studies. As of May 2024, less than ten candidates, like GNC-035, GNC-038 etc., are currently enduring clinical studies, many of which have moved into phase II stage of development. For instance, Sichuan Baili Pharmaceutical in collaboration with SystImmune, in February 2023, have begun an open, multicenter, phase IB/II clinical study in order to assess the safety, tolerability, pharmacokinetics/pharmacokinetics, in addition to antitumor activity of GNC-038 injection in relapsed or refractory NK/ T-cell lymphoma, vascular immunomother T cell lymphoma, and other relapsed or refractory non-Hodgkin lymphoma.
Interalia, in the recent years, the combinations of tetraspecific antibodies is also countersigning an inclining market trend for the management of cancer. Although, the assumption of combination approach of tetraspecific antibodies seems to be out of the box, conversely, the arrival of Molecular Partners up-to-the-minute candidate, MP0533 comes into depiction. Thanks to Molecular Partners innovation and advancement in the domain led to the combination strategies of tetraspecific antibodies. The company has developed a novel tetraspecific, half-life extended, T cell engaging DARPin therapy called MP0533, which targets 4 antigens (CD70, CD123, CD33 in addition to CD3) for the treatment of acute myeloid leukemia (AML).
As per recent market developments, it is conspicuous that the global tetraspecific antibodies domain will revolutionize the treatment portrait for cancer ailments in next 5 to 7 years due to the fact that the up-to-date emphasis of pharma and biotech companies oscillates in the sphere of targeted therapies. In subsequent decennium, the tetraspecific antibody is predicted to clench spotlight in multispecific arena, along with monospecific and bispecific antibodies.
Hitherto, there are quite a few tetraspecific antibody contenders in the preclinical and developmental stages. These candidates are being tested in various solid and hematological cancers, the most of which have been created for cancer. Albeit, at present, no tetraspecific antibodies have been launched into global market, it is envisaged that the advert of the first tetraspecific antibody will encourage corporations across the globe in expanding clinical pipelines as well as drive the creation of further antibodies. This might also stimulate the establishment of new-fangled tetraspecific antibodies with superior selectivity.
