Abstract (en)

[origin: WO2021037319A1] The present invention relates to a method for providing a biomarker of the efficacy and/or safety of an antibody or antigen-binding fragment thereof using immunohistochemical methods. Former immunohistochemical methods using paraffin embedded samples in combination with a murine 8H9 antibody, have not provided satisfactory results. The present invention discloses a method that can use both frozen samples as well as paraffin embedded samples. Further, the present invention relates to a kit of parts adapted to carry out the inventive method. Moreover, the invention relates to a method of treating a cancer, comprising measuring or verifying a biomarker of the efficacy, the suitability and/or safety of an antibody or antigen-binding fragment thereof, wherein said antibody or antigen-binding fragment thereof is used for treating said cancer.
