The overexpression of transferrin receptor 1 (TfR1) has been reported in several cancer types but is also expressed in normal cell types such as erythroblasts. On the other hand, epidermal growth factor receptor (EGFR) is highly expressed in epithelial carcinomas.
Researchers from Beigene (Beijing) Co. Ltd. have disclosed preclinical data for BGB-B167, a first-in-class immunoglobulin G (IgG)-based bispecific antibody (bsAb) targeting 4-1BB and CEA, being developed for the treatment of advanced or metastatic solid tumors.
It has been previously demonstrated that B7-H3 and EGFR are co-expressed in multiple solid tumors. At the ongoing AACR meeting in San Diego, researchers from Innovent Biologics Inc. presented preclinical data for their bispecific antibody (bsAb), IBI-334, against B7-H3 and EGFR.
Aethon Therapeutics Inc. has entered into a collaboration agreement with Revolution Medicines Inc. under which Aethon will use its Hapimmune platform to discover novel bispecific antibodies to mount an immune attack directed towards cancer cells hit by Revolution Medicines’ RAS(ON) inhibitors.
Context Therapeutics Inc. has submitted an IND application to the FDA to begin a first-in-human phase I study of CTIM-76 in patients with claudin 6 (CLDN6)-positive gynecologic and testicular cancers.
Researchers presented the development of a translational pharmacokinetic (PK)/receptor occupancy (RO) model of the tetravalent bispecific antibody (bsAb) CTX-8371 (Compass Therapeutics LLC) with the aim of investigating the possible effects of tetravalency compared to bivalency on RO and target internalization.
Biomunex Pharmaceuticals SAS has signed an exclusive license and exploitation agreement with Institut Curie for the development of a new class of antibodies.
Biocytocgen Pharmaceuticals (Beijing) Co. Ltd. has entered into an exclusive option and license agreement with Radiance Biopharma Inc., granting Radiance an option to license from Biocytogen a first-in-class fully human anti-HER2/TROP2 bispecific antibody-drug conjugate (BsADC).
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.
