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.
The week began with PDUFA-delaying news for Regeneron Pharmaceuticals Inc. The company said it received two complete response letters (CRLs) from the U.S. FDA regarding the priority BLA for its bispecific antibody to treat lymphoma, odronextamab.
Chinese biotechs Biotheus Inc. and Hansoh Pharmaceutical Group Co. Ltd. partnered again under a new potential ¥5 billion (US$698.98 million) deal to develop bispecific antibody-drug conjugates (BsADCs), using Biotheus’ EGFR-cMet bispecific antibody.

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.
Elpiscience Biopharma Ltd. is out-licensing to Astellas Pharma Inc. two preclinical bispecific macrophage engagers – ES-019, an anti-PD-L1/SIRPα bispecific antibody, and another unnamed program – in a deal worth up to $1.7 billion. The deal marks the Shanghai-based company’s first out-licensing deal, Elpiscience CEO Darren Ji told BioWorld, noting that Astellas will have global rights to both molecules with a potential to in-license two more.
