Nona Biosciences offers specialized solutions in bispecific and multispecific antibody engineering, addressing the complex challenges associated with next-generation therapies. To ensure the success of these advanced modalities, we provide end-to-end support, from antigen preparation to developability assessments, enabling seamless candidate profiling to assess and de-risk the development process. Utilizing heavy chain-only antibody (HCAb) engineering and Harbour Mice® technology, we produce fully human antibodies with excellent stability, solubility, and low immunogenicity. Compared to camelid-derived VHH domains, Nona’s HCAbs retain all the advantages of small antibody formats while being fully human, highly druggable, and less immunogenic, providing a stronger starting point for therapeutic development.
Nona’s modular antibody platform allows for the systematic screening of bispecific and multispecific constructs through a stepwise permutation approach. Rather than relying on pooled or high-throughput format mixing, we carefully test and compare variable elements such as binder position, Fc geometry, valency, and spatial orientation one at a time. This data-driven strategy ensures early identification of the most promising constructs, improving stability, manufacturability, and function, setting the stage for efficient downstream development.
Even after optimal format selection, bi/multispecific antibodies present distinct development challenges including light chain pairing mismatches, dual-target binding stability, and complex post-translational modifications. Our HCAb-based formats are engineered to avoid these pitfalls from the outset, simplifying production and reducing downstream variability.
To ensure only the most viable candidates advance, we apply a rigorous combination of developability analytics and in vivo validation. Early-stage stress testing, predictive assays, and PK/PD studies provide critical insights into manufacturability, safety, and overall therapeutic potential.
