Next-generation botulinum neurotoxin therapeutics
We engineer next-generation botulinum neurotoxins to enable more precise and effective treatments for neuromuscular and neurological disorders.
Our Technology
Advancing the Science of Neuronal Recognition
Our technology builds on decades of research into how botulinum neurotoxins recognise and interact with the neuronal surface.
Precision by design
Botulinum neurotoxins are highly selective molecules that recognise and enter specific neurons with remarkable precision.
Natural neuronal specificity
Potent intracellular activity
Engineered for improved binding
We engineer improved toxin-receptor interactions to achieve more precise neuronal targeting.
Designed to improve patient outcomes
Our products aim to deliver more durable and predictable therapeutic performances.
Advancing the science behind next-generation neuromodulators
Built on world-class science
Our extensive track record of high-impact academic and industry collaborations has shown that refined receptor interactions can translate into stronger neuronal activity and improved therapeutic potential.
Innovations beyond what nature provides
Building on these insights, we are creating proprietary, synthetic neuromodulator molecules with new receptor-engagement concepts not found in natural toxins. Our lead candidates are protected by global patent filings and represent a distinct platform for future therapeutic development.
