Radiopharm Theranostics Ltd. announced that the U.S. FDA has cleared the IND application for betabart (RV-01), its Lu177-B7H3 monoclonal antibody designed with strong affinity for the 4Ig isoform of B7-H3 that is highly expressed in tumors and not in healthy tissues.

The OX40/OX40L costimulatory pathway is crucial for effective T-cell activation and is inducibly expressed in response to immunological stimulation. Targeting OX40L has demonstrated safety and efficacy in preclinical studies using nonhuman primate models of kidney and heart transplantation.

Monoclonal antibodies show strong therapeutic potential against neurodegenerative diseases, but a major challenge is ensuring that they can arrive unharmed in the brain at sufficient concentrations. One way around this challenge is to vectorize the monoclonal antibody: encode it within a vector that can infect target cells in the brain and express the antibody in situ.

Abion Inc. signed a potential $1.315 billion deal with an anonymous partner June 22, granting the counterparty exclusive global rights to a preclinical claudin 3-targeting monoclonal antibody, ABN-501, and the potential to license four more protein targeting antibodies.

Hemab ApS recently presented preclinical data on its human monoclonal antibody against von Willebrand factor (vWF), HMB-002, for the treatment of von Willebrand disease.

Researchers at the Olivia Newton-John Cancer Research Institute and collaborators have developed a new anti-HER2 monoclonal antibody, mAb104, which targets a conformationally exposed, tumor-specific epitope in domain II of the HER2 protein.

Mindimmune Therapeutics Inc. has been awarded a grant by Rhode Island Life Science Hub to accelerate preclinical development work on MITI-101 for the treatment of mild to moderate Alzheimer’s disease. The award will accelerate development work needed to start first-in-human studies.

Biocytogen Pharmaceuticals (Beijing) Co. Ltd. and Nanjing Chia Tai Tianqing Pharmaceutical Co. Ltd. have announced IND clearance by China’s National Medical Products Administration (NMPA) for NTB-003 (formerly BCG-009) for thyroid eye disease.
