Bispecific antibodies acting through CEACAM5/CD3 targeting have limited efficacy due to dose-limiting toxicities, insufficient T-cell activation and formation of anti-drug antibodies (ADAs). Researchers from Novimmune SA and Lampkap Bio Alpha AG have published data on a CEACM5/CD3 bispecific antibody, NILK-2301, which is formed by a heavy chain plus two different light chains (kappa and lambda body) as a potential immunotherapeutic with better efficacy and lower potential for ADA formation.
In a recent publication in Scientific Reports, researchers at City of Hope and collaborators presented a novel CS1 bsAb, called CS1-dbBiTE, conjugating an intact anti-CS1 antibody (elotuzumab) and an anti-human OKT3 antibody at their respective hinge regions using Click chemistry.
High expression of CD123, the IL-3 receptor α chain (IL-3α), is observed on both leukemic blasts and leukemic stem cells, thus suggesting it can be considered an attractive therapeutic target in AML.
Researchers from Seoul National University presented results of preclinical evaluation of a new TNF-α/OX40L bispecific antibody, IMB-101, being developed for the treatment of rheumatoid arthritis (RA).
Ibio Inc. has expanded its artificial intelligence (AI)-powered technology offering with the launch of Shieldtx, an antibody masking technology designed to enable specific, highly targeted antibody delivery to diseased tissue without harming healthy tissue.
Sparx Biopharmaceutical Corp. has received FDA approval of its IND application for SPX-303, a first-in-class anti-LILRB2/PD-L1 bispecific antibody drug candidate.
Researchers from Biontech SE and Genmab BV presented the discovery and preclinical evaluation of a novel Duobody-EpCAMx4-1BB (BNT314/GEN1059), a novel Fc-inert immunomodulatory bispecific antibody (bsAb) designed to boost antitumor immune responses through EpCAM-dependent 4-1BB agonistic activity.
Data regarding an innovative bispecific antibody – CPL-976 (CPBT-0976) – were recently reported by Celon Pharma SA. Bispecific antibodies targeting more than one antigen on cancer cells improve the specificity and effectiveness of the therapy, and could be utilized for targeting the defense mechanisms of cancer cells, such PD-L1 or EGFR, VEGFR and AXL.
Ono Pharmaceutical Co. Ltd. has entered into a drug discovery collaboration agreement with Adimab LLC to discover and develop innovative antibody drugs in the oncology field.
