Merus N.V. has announced the upcoming presentation of initial interim data from a phase 2 trial evaluating petosemtamab, a bispecific antibody targeting EGFR and LGR5, in metastatic colorectal cancer (mCRC). The data, which assess petosemtamab in combination with standard chemotherapy in first- and second-line mCRC and as monotherapy in heavily pretreated (third-line and beyond) mCRC, will be presented during a plenary session at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics.
