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.
Company News: VAXIMM Receives Grant to Expand Pipeline of Oral Cancer Vaccines
VAXIMM AG, a Swiss-German biotech company focusing on cancer vaccines, today announced that its German subsidiary VAXIMM GmbH has been awarded a grant from the leading-edge BioRN cluster “Cell-based and Molecular Medicine” to expand its oral T-cell vaccine technology platform. The cluster competition is a program of Germany´s Federal Ministry of Education and Research (BMBF) to promote top-notch innovation in Germany.
VAXIMM’s lead candidate VXM01 is an oral T-cell vaccine, which targets the tumor vasculature. It is currently in Phase I/II clinical evaluation in pancreatic cancer patients at the Heidelberg University Hospital. The funding from the leading-edge cluster program will be used to develop additional cancer vaccines complementary to VXM01, which are based on the same oral T-cell vaccine technology. A second candidate (VXM06), which targets an undisclosed, abundant, tumor-specific antigen, is already in preclinical development. Two further product candidates are at discovery stage.
VAXIMM’s oral T-cell vaccine technology has a number of advantages. The platform can easily and rapidly generate new vaccines, including multivalent vaccines. The resulting products combine oral efficacy with safety and excellent tolerability. Moreover, the vaccines do not require a complex manufacturing infrastructure.
Company News: Merus Receives EP Patent Covering the Expression of Defined Antibody Combinations
Merus B.V., a biopharmaceutical company focused on multispecific human antibody therapeutics, announced today that it has been granted the first European patent covering its Oligoclonics® technology from a patent family that already comprises 4 issued US patents. The Oligoclonics® technology entails the manufacturing of at least three antibodies with different specificities by a single production cell line, thereby providing for combinations of human antibodies as a single therapeutic.
It has been demonstrated in clinical trials and disease models that combinations of antibodies are more efficacious than therapies based on single monoclonal antibodies alone. The Oligoclonics® technology is designed to provide important developmental and therapeutic value. It offers a platform for the stable, high-yield production of fully human, natural IgG antibody combinations by a single cell line using strategies currently exploited for conventional monoclonal antibodies in a manner that is cost-effective and acceptable to regulatory authorities.
“The therapeutic antibody field is moving towards combination therapies, either by combining individual monoclonal antibodies or by applying bispecific formats, to overcome the limited potency of monoclonal antibodies often observed in indications like oncology,” said Ton Logtenberg, CEO of Merus. “The Oligoclonics® technology provides a platform that allows for the cost-effective development and manufacturing of multispecific combinations of antibodies with more potent clinical effects. The key to the Oligoclonics® technology is that all antibodies produced by the clonal manufacturing cell line share a common light chain (cLC). With our recent announcement of MeMo®, a transgenic mouse for the generation of human cLC monoclonal antibodies, we are complementing our technology base with the aim to expand our pipeline of innovative cLC antibody products.”
Company News: Jean-Paul Prieels joins VAXIMM’s Board of Directors
VAXIMM AG, a Swiss-German biotech spin-off from Merck KGaA focusing on cancer vaccines, announced today the appointment of Jean-Paul Prieels as a new member of its Board of Directors.
Dr. Prieels is a renowned industry expert in the vaccine field. He held various executive positions at GlaxoSmithKline, where he headed the vaccine research and development in Rixensart, Belgium, among others. Dr. Prieels, who joined GlaxoSmithKline Biologicals (formerly SmithKline Beecham Biologicals) in 1987, has been instrumental in developing several marketed vaccines, including cervical cancer vaccine Cervarix™, Rotarix™ to protect from rotavirus infection, and Synflorix™ for the prevention of pneumococcal infections. He retired from GSK as Senior Vice President Research and Development in early 2011 and is currently a board member of several biotech companies in the vaccine field.
VAXIMM’s lead product candidate VXM01 is being evaluated in a placebo-controlled phase I dose escalation study enrolling up to 45 pancreatic cancer patients, with results expected in H1, 2013.
