Title: Innovations by Robertus Cornelis Roovers in Targeted Cancer Therapies

Introduction

Roberts Cornelis Roovers is a distinguished inventor based in Utrecht, Netherlands, noted for his contributions to the field of biomedicine, particularly concerning targeted cancer therapies. With a remarkable portfolio of three patents, Roovers is recognized for his innovative approaches to treating tumors with bispecific antibodies.

Latest Patents

Among his most recent patents, he has developed methods for treating subjects having EGFR-positive and/or ErbB-3-positive tumors. This invention involves bispecific antibodies featuring a first antigen-binding site that targets the epidermal growth factor receptor (EGFR) and a second site that binds ErbB-3. Notably, these antibodies exhibit a half maximal growth inhibitory concentration (IC50) of less than 200 pM for inhibiting the growth induced by EGFR and/or ErbB-3 ligands in Bx PC3 cells. Further, the patent elaborates on methods for producing these bispecific antibodies and the therapeutic approaches utilizing them.

Another significant patent involves antibodies that specifically bind both EGFR and the MET proto-oncogene, receptor tyrosine kinase (cMET). This invention describes bispecific antibodies composed of a first variable domain that targets the extracellular portion of EGFR and a second variable domain that targets cMET, potentially enhancing the efficacy of cancer treatments. Moreover, these antibodies may include a common light chain and can be designed as full-length human antibodies, with certain embodiments specified as an IgG1 format antibody with an anti-EGFR, anti-cMET stoichiometry of 1:1.
