Company News: Merus Achieves Milestone with Novartis Option Fund
– Company Reaches Milestone in Biclonics™ Program Partnered with Novartis –
Merus B.V., a biopharmaceutical company focusing on innovative human antibody therapeutics, today announced it has met the second milestone in its option agreement with the Novartis Option Fund (NOF). The achievement triggers an undisclosed milestone payment.
In 2010, Merus had entered into an option agreement with the Novartis Option Fund for an exclusive license to one of Merus’ oncology programs. The deal grants the Novartis Option Fund rights to a product candidate created by the Biclonics™ and Oligoclonics™ technologies of Merus. Merus is potentially entitled to milestone and license payments in excess of $200 million, as well as royalties.
Ton Logtenberg, CEO and founder of Merus, commented: “Reaching this key milestone in our program partnered with NOF underlines the power of our platform to generate antibodies addressing multiple targets simultaneously with high potency and the desired functional activity.”
Company News: OcellO and Merus Sign Agreement for Screening Bispecific Cancer Antibodies
OcellO B.V. and Merus B.V. have entered into a collaboration under which OcellO will provide screening services to Merus. OcellO, a biotech company providing drug discovery screening services using its proprietary high throughput 3D cell culture-based screening platform, will use its platform to profile bispecific antibodies designed by Merus for the treatment of cancer. Financial details of the collaboration have not been disclosed.
Mark Throsby, Chief Operating Officer at Merus, commented: “The strength of our approach is its ability to generate thousands of full-length, bispecific human IgG antibodies addressing combinations of targets expressed by tumor cells. OcellO is able to provide high quality data on the functional properties of large panels of bispecific antibodies. These data can’t be obtained from other in vitro screening assays and are pivotal in identifying antibody leads with unique modes of action.”
Company News: Merus Selects Clinical Candidate for the Treatment of Acute Myeloid Leukemia (AML)
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.
Company News: Merus Announces the Full Validation of Its MeMo® Transgenic Mouse for Common Light Chain Human Antibodies
Merus B.V., a biopharmaceutical company focused on innovative human antibody therapeutics, announced today the full validation of its transgenic MeMo® mouse for common light chain human antibodies. The MeMo® mouse creates human antibody diversity using a large repertoire of human heavy chains paired with a common human light chain.
“Over the last year, we have immunized MeMo® mice with half a dozen antigens and analyzed the immune response,” said Mark Throsby, COO at Merus. “We are extremely excited by the performance of the MeMo® technology; serum antibody titers as well as size, diversity, functionality and developability of antibody panels are comparable to those of wild type mice.”
“In MeMo®, a single human light chain drives the generation of a normal B cell compartment as well as supports a robust immune response,” said Ton Logtenberg, CEO and founder of Merus. “The large and diverse panels of high-quality human antibodies that we retrieve from MeMo® show that this platform is comparable to the best-in-class transgenic platforms using diversified heavy and light chains.”
Because of the common light chain, MeMo®-derived antibodies can be immediately used to rapidly generate thousands of bispecific antibodies (Biclonics™) and combinations of antibodies (Oligoclonics®) for functional screening. Merus has shown that the quality and diversity of common light chain antibodies drives the success of identifying Biclonics™ with unprecedented potencies for application in oncology. The MeMo® mouse is available for licensing.
