Merus B.V., a biopharmaceutical company focusing on innovative human antibody therapeutics, today announced that it has selected MCLA-117 as lead candidate for clinical studies in patients with acute myeloid leukemia (AML). MCLA-117 is a human, full-length IgG bispecific antibody, which activates the patient’s own immune system by simultaneously binding to the CLEC12A molecule expressed by AML tumor cells and the CD3 molecule expressed by T cells. MCLA-117-mediated co-engagement of CLEC12A and CD3 results in the potent killing of cancerous AML cells and their malignant precursors. Merus intends to start phase I clinical trials with MCLA-117 in 2014.
The antibody is based on Merus’ Biclonics™ ENGAGE platform. Human bispecific antibodies from this platform can be manufactured and administered like conventional, full-length IgG molecules, thereby providing for high yield, good stability and a long serum half life. In addition, bispecific antibodies from the Biclonics™ ENGAGE platform have a modified constant region to abrogate unwanted clinical cytokine release.
Prof. Gert Ossenkoppele from the department of hematology at the Free University Medical Centre in Amsterdam, The Netherlands, will be the lead investigator of the first MCLA-117 Phase I study.
