Bispecific design as an engineering discipline

At Bivalent Bio, we treat bispecific design as an engineering discipline. Every molecule begins with a clearly defined biological hypothesis, and every format decision — geometry, valency, linker chemistry, affinity ratios — is made to serve that hypothesis rather than the other way around.

Our approach

The right scaffold for each target pair

We work across multiple bispecific formats, including IgG-like architectures, tandem scFv constructs, and asymmetric heterodimers, selecting the right scaffold for each target pair.

Our discovery process integrates structural modelling, high-throughput screening, and developability assessment from the earliest stages, so molecules that progress are not only potent but manufacturable.

Three pillars

How we engineer for the clinic

Rational format selection

Target biology drives architecture. We do not force every programme into a single platform.

Developability by design

CMC-aware engineering from lead identification onwards. Stability, aggregation behaviour, and expression yield are evaluated alongside potency.

Translational rigour

In vivo PK, biodistribution, and mechanism-of-action work are built into early candidate selection.

Therapeutic areas

Where dual engagement matters most

Oncology

A focus on solid tumours where T-cell engagement and tumour-microenvironment modulation are central to durable response.

Immune-mediated disease

Selected programmes where dual engagement offers a clear mechanistic rationale across autoimmunity and inflammation.
