The antibody was shown to completely block β-catenin signaling, demonstrating it is a specific inhibitor of RSPO2. The antibody blocked soluble RSPO2 binding to LGR5. The antibody had a binding affinity for human RSPO2 of 0.14 nM and mouse RSPO2 of 0.35 nM. The antibody demonstrated strong anti-tumor growth activity in combination with gemcitabine in a pancreatic xenograft model and inhibition of pancreatic tumor growth in vivo as a single agent and in combination with additional therapeutic agents. The humanized version of the antibody was produced. The humanized version had a binding affinity for human RSPO2 of 0.13 nM (US8802097B2).
This chimeric rabbit antibody was made using the variable domain sequences of the original Human IgG1 format, for improved compatibility with existing reagents, assays and techniques.
