Elpiscience Biopharmaceuticals Inc. has announced Center of Drug Evaluation (CDE) clearance of its IND application for ES-014 for a phase I study in patients with advanced solid tumors.
CD40-targeting therapies have been proposed as an interesting alternative to overcome resistance to immune checkpoint inhibitors. In particular, bispecific CD40 antibodies can target CD40 more efficiently and safely than monospecific therapies. In a recent publication, researchers at Alligator Bioscience AB and collaborators demonstrate that bispecific antibodies targeting CD40 and tumor-associated antigens (TAA) can enhance priming of tumor-specific T cells in vivo.
Context Therapeutics Inc. has selected CTIM-76, a T cell-engaging bispecific antibody, as its lead clinical development candidate to target Claudin-6 (CLDN6)-positive cancers. Resulting from a research collaboration and licensing agreement with Integral Molecular Inc., CTIM-76 is a CLDN6 x CD3 bispecific antibody that incorporates a highly selective CLDN6 binding arm and a CD3 binding single-chain Fv domain in an IgG format with a silenced Fc that is designed to be functionally monovalent to avoid aberrant T-cell activation and to enhance the safety profile.
Abpro Corp. has entered into a strategic partnership with Celltrion Holdings Co. Ltd. for ABP-102, a bispecific antibody therapy for patients with HER2+ cancer, including breast, gastric and pancreatic cancers.
Invenra Inc. has announced preclinical data supporting the ongoing development of INV-322, a Sniper bispecific antibody co-targeting CTLA-4 and CD25 for cancer developed using Invenra's B-Body Platform.
Lamkap Bio Alpha AG's κλ bispecific antibodies include a κ light chain recognizing one target and a λ light chain recognizing a second target. The company has presented data showing the benefit of combining a bispecific antibody targeting CEA (CEACAM5) on tumor cells and CD3 on T cells, NILK-2301, and a bispecific antibody targeting CEA on tumor cells and CD28 on T cells, NILK-3301.
