Transforming the treatment of disease with highly selective therapeutic antibodies.

The Selectivity Challenge

Existing therapeutics indiscriminately kill both healthy and diseased cells

Solid tumours are hard to treat because, in the majority of instances, they can only be targeted by antibodies using tumour-associated antigens (TAAs). Healthy cells that also express these TAAs are caught in the crossfire, resulting in on-target, off-tumour toxicity.
Tackling On-target, Off-tumour Toxicity

Unlocking killing selectivity through avidity

The biological mechanism that we’ve used to achieve killing selectivity is based on the principle of avidity. By harnessing avidity-driven selectivity, our optimised T-cell engagers are able to differentiate between a healthy and diseased cell based on differential TAA expression.

Conventional methods marginally widen therapeutic windows

Nectin-4 is a tumour-associated antigen (TAA) that is commonly overexpressed on numerous solid tumour types, including urothelial, head and neck, and triple-negative breast cancer. Nectin-4 is also expressed at low levels on normal, healthy tissues, which limits current ADC therapies due to high rates of dose-limiting, on-target, off-tumour toxicities. This highlights a need for alternative approaches for anti-cancer therapeutics that can selectively target Nectin-4 expressing solid tumours. 

Through the tight integration of high-throughput functional cell-based experimentation with machine learning (ML), LabGenius’ proprietary lead optimisation platform (EVA™) generated a highly selective and potent trivalent VHH-based Nectin-4 x CD3 T-cell engager (TCE), LGTX-101. By harnessing avidity-driven selectivity, LGTX-101 is able to differentiate between healthy and diseased cells based on differential TAA expression, demonstrating >70,000-fold killing selectivity in a T-cell-mediated tumour cell killing assay. LGTX-101 is highly efficacious in vivo with complete tumour regression observed in all tumour-bearing mice treated with our lead candidate.
