Advancing clustering antibodies to correct the root cause of genetic diseases
Our Approach
Dysregulated cellular signaling pathways lie at the heart of many chronic illnesses, yet treatments for these diseases often focus on symptom management rather than addressing the root cause of the disease. Clustering antibodies can regulate a signaling cascade by binding two or more receptors and bringing them together in a highly specific conformation that enables activation or inhibition of downstream signaling. These antibodies promote complex assembly of receptors to either stimulate or inhibit pathogenically altered signaling pathways, paving the way for treatments that bring disease modification within reach.
Given the many potential binding sites between each receptor and an antibody, nearly infinite binding combinations exist, of which only a small subset will induce cell signaling. Historically, this has made identifying or rationally designing clustering antibodies difficult. The DIAGONAL Product Engine solves this challenge, combining proprietary computational and experimental techniques, enabling us to sift through billions of combinations at unprecedented speeds and identify clustering antibodies with high fidelity.
Our Pipeline
Our approach is effective and reliable, yielding a portfolio of novel treatments that span multiple different receptor classes and diseases that impact millions around the globe. Our multi-specific clustering antibodies combine the advantages of established antibody therapeutics—including high specificity, easy manufacturability, and straightforward patient administration—with the disease modifying potential of novel mechanisms of action.

Our Platform
Our platform enables us to rapidly discover clustering antibodies against any receptor complex of interest in a timeframe unimaginable using legacy approaches.
Generation of deep immune repertoires of sequences to each target
We generate immune repertoires containing ~200,000 distinct antibody sequences that cover all possible binding sites on each receptor. Because we build multi-specific antibodies, there are >10 billion possible combinations.
Clustering by shape of antibodies
Shapes of antibodies predicted by computational methods are clustered to eliminate redundancies.
Binning by complementarity to the receptor
Distinctly shaped sequences are then grouped by their unique binding spots on the receptors.
Generation of antibodies based on possible bin combinations
One representative binder from each group is then combined into a multispecific antibody that is produced for experimental testing.
Optimizing molecular sequence characteristics
Once we identify a combination that induces signaling, we can go back to its group and cluster to find additional binders that elicit the desired effect. This step allows us to pick molecules with the best characteristics.
Characterize in in vitro and in vivo models
These molecules are optimized using proprietary technologies to derive optimal antibodies to test in vitro and in vivo. This process leads us to clinical candidate selection.
