Registration for our next webinar, “Precision Execution of Bispecifics at Scale from Design to Delivery“, is now open!
Novel therapeutic modalities such as bispecific antibodies are increasingly being explored as more effective alternatives to monoclonal antibodies for a range of diseases. Therapeutics such as bispecifics, can have a combinatorial effect by targeting two antigens, resulting in treatments with enhanced utility, higher efficacy, fewer side effects and less resistance compared to mAbs.
Generating a bispecific antibody, which is correctly and stably paired, is a major production concern. Many solutions require significant changes to native antibody structure, which increases antibody complexity and forces adaptation of downstream processes. While a various platforms have been developed to mitigate Heavy-Light chain (HC-LC) mispairing, there are many other rate limiting steps for efficiently expressing these molecules in a CHO system. bYlok® technology is a design engineering approach that stabilise the interaction between the HC and LC, essentially removing the mispairing problem whilst retaining a more natural antibody structure.
This presentation will introduce you to a mechanistic review of the bispecific pipeline to demonstrate how a various tools and technologies can enable you execute bispecifics. Case studies will be presented to show how the bYlok® technology can be used to stabilise and select for novel bispecifics from a panel of parental immunotherapeutic mAbs. Our data demonstrates that correct heterodimerisation can be achieved consistently and how standard downstream purification processes can be used during production.
