The targeted delivery of radionucleotides into tumors, known as radioimmunotherapy (RIT), has proven effective mainly in hematological cancer treatment, but its usefulness in solid tumors needs further exploration. Researchers from Oncoone Research & Development GmbH described the use of Pretarg-it, a novel pre-targeted RIT strategy that consists of ON-105 and the radioactively labeled DOTA-di-HSG peptide.
Beijing Gensciences Inc. has developed a FVIIIa-mimetic bispecific antibody named SS-315 for the treatment of hemophilia A. SS-315 was developed by targeting FX with its upper Fab arms and FIXa with its down-side scFv arms, respectively; the hemostatic potential of SS-315 was investigated in vitro and in vivo.
Scientists at the University of Washington have engineered human plasma B cells modified to express long-lasting bispecific antibodies that could be used to treat leukemia without requiring continuous dosing.
“We are trying to engineer plasma cells to make as a stable source for biologic drugs. One thing that is really unique about plasma cells is that they can live for a really long time … up to 10 years or even 100 years depending on the type of plasma cell that that you make,” Richard James, senior author of the study, principal investigator at Seattle Children’s Research Institute, and associate professor at the University of Washington, told BioWorld.
CDR-Life Inc. has expanded its pipeline of novel T-cell engagers (TCE) with the addition of CDR-813 and CDR-505. CDR-813 is a highly potent and selective TCE candidate targeting tumors expressing PRAME (preferentially expressed antigen in melanoma) in HLA-A*02:01 patients.
Zymeworks Inc. has obtained IND clearance from the FDA for ZW-171, a novel T-cell targeting bispecific antibody for mesothelin (MSLN)-expressing cancers. Clinical development will begin this year, and additional applications will be filed in the second half of the year seeking trial clearances in other territories.
Indupro Inc. has announced a $85 million series A financing to support its work on precisely defining the spatial proximity of proteins on the surface of cells with high therapeutic potential across a broad range of indications and applications, including for the treatment of cancer and autoimmune diseases.
Bispecific T-cell-engaging antibodies have emerged as therapeutic options for the treatment of cancer, but limitations such as short half-life remain to be addressed. Researchers from Biontech SE reported the preclinical pharmacology and efficacy of BNT-142, a bispecific antibody targeting claudin-6 (CLDN6) and the T-cell marker CD3.
Newco Commit Biologics ApS has arrived on the scene after raising €16 million (US$17.2 million) in a seed round to advance bispecific antibodies that are designed to activate the complement system and direct it to selectively kill cancer cells.
Context Therapeutics Inc. has received FDA clearance of its IND application for CTIM-76, a Claudin 6 (CLDN6) x CD3 T-cell engaging bispecific antibody.
