Researchers at Washington University in St. Louis have used click chemistry to link a second antibody to a pre-existing antibody-drug conjugate (ADC) in vivo. In preclinical models of HER2 and EGFR co-expressing pancreatic, breast and gastric tumors, sequential administration of the ADC and the second antibody was better at shrinking tumors than either ADC monotherapy or a combination of antibody and ADC treatment.

Sightera Biosciences BV announced it has raised €3 million (US$3.5 million) in pre-seed funding. The funding will be used to extend the company’s platform technology and asset portfolio, including its lead program in oncology, SIGHT-001.

Human cytomegalovirus (CMV) is a clinical challenge in infants and immunocompromised individuals, since no licensed vaccine exists. Vaccine development is complex due to several factors, including viral latency, genomic complexity and immune evasion, among others. Evaxion A/S recently presented data on its proprietary AI-immunology platform used to create the EVX-V1 vaccine for CMV infection.
