Company News: Merus Granted European Patent on MeMo®, a Transgenic Mouse for Generating the Building Blocks of Therapeutic Human Bispecific Antibodies
– Invention provides unique technology base for therapeutic human bispecific antibodies
– Full-length IgG format of bispecific antibodies facilitates standard manufacturing processes
Merus B.V., a biopharmaceutical company focusing on innovative antibody therapeutics, today announced that it has been granted a European patent on its MeMo® transgenic mouse for the generation of common light chain human antibodies. Using standard industry processes, MeMo®-derived common light chain antibodies can be manufactured in clonal cell lines to efficiently obtain full-length IgG human bispecific antibodies (branded as Biclonics™) for therapy.
“We are very pleased about this important patent as it underlines our unique approach to creating improved antibody therapeutics,” said Ton Logtenberg, CEO of Merus. “MeMo® is distinct from other transgenic mice for human antibodies because the common light chain facilitates co-expression of two antibodies in a single cell to generate functional bispecific antibodies. By screening thousands of bispecific antibodies in cell-based assays, antibody therapeutics with truly superior functional activities are efficiently identified. The full-length IgG format provides for using established, ‘off-the-shelve’ analytical and manufacturing processes which are already in place for therapeutic monoclonal antibodies.”
“This is a major accomplishment of Merus,” said Jason Avery, CBO of Merus. “The company has built an exceptional product and technology base for superior therapeutics that combine the benefits of full-length IgG monoclonal antibodies with the ability of simultaneously addressing multiple disease targets. MeMo® is a source of large panels of high quality human antibodies that may be used to rapidly identify bispecific antibody leads. We are offering biopharmaceutical companies worldwide a non-exclusive license to MeMo®. There are no target restrictions and license terms are flexible.”
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: Merus Announces Appointment of Jason Avery as Chief Business Officer
Merus B.V., a biopharmaceutical company focused on multispecific human antibody therapeutics, announced today that Jason Avery has been appointed as Chief Business Officer.
With a professional background as Head of Business Development at Affitech A/S and Chief Business Officer at Cambridge Antibody Technology, Jason Avery brings extensive industry experience to Merus.
“Jason comes to Merus with a wealth of experience in Business Development, in particular in the antibody space, and we are delighted to have him join the team,” said Dr Ton Logtenberg, CEO of Merus B.V. “As our multispecific human antibody platforms have matured and consistently yield lead candidates for clinical development, Jason’s expertise will be invaluable to reach our ambitious business goals.”
“Merus is one of the most impressive companies in the antibody technology and product space,” said Jason Avery. “The combination of MeMo®, the common light-chain transgenic mouse, and Merus’ antibody format technology facilitates unprecedented ease in the discovery, development and manufacturing of bispecific antibodies. I look forward to progressing the commercial success of Merus´ discriminative pipeline of owned and partnered antibody products. I am very excited to be joining such an experienced management team.”
