Ymmunobio and PSI Secure Innosuisse Grant to Advance Radio-pharmaceutical YB-800 (PRNewswire) - "Ymmunobio (YB) is excited to share that they in collaboration with the Paul Scherrer Institute (PSI) have received Innosuisse support to develop innovative radioactive loaded antibodies for the treatment and diagnostic of solid tumors based on YBs proprietary YB-800. The Innosuisse support validates Ymmunobio's approach to targeted solid tumor therapy using a new and first in class target with a high prevalence in cancer patients....The newly developed antibodies will utilize a linker attached to YB-800, capable of carrying any radioactive isotope for the treatment and diagnostic of solid tumors. Ymmunobio plans to leverage this cutting-edge technology to treat patients with solid tumors who express the new marker."

YB-800, a monoclonal antibody targeting the human neuronal pentraxin receptor (NPTXR), as a potential candidate for the design of a first in class antibody drug conjugate (ADC) as novel therapeutic intervention in gastro-intestinal cancers. (ASCO 2024) - "In conclusion, YB-800 represents a first in class ADC candidate that could be used as novel treatment for gastro-intestinal cancers. Hence, as initial proof of concept, tesirine (DNA intercalating agent) and deruxtecan (topoisomerase I inhibitor) containing protease-sensitive linkers were coupled to YB-800 by stochastic maleimide conjugations to interchain cysteines. Initial results with YB-800-based ADCs will be discussed."
