Company Overview

4B Technologies (4B Tech) is a biotech company specializing in the development of transformative medicines for nervous system diseases. 

CNS diseases represent one of the fastest growing and most impactful health threats, affecting hundreds of millions of patients worldwide. Despite of tremendous efforts and progresses in decades, effective and safe therapeutics for major CNS illness are scarce and remain an urgent unmet need.

4B Tech was founded with its mission to focus on innovative medicines for neurodegenerative and other neurological disorders. With deep insights in neurosciences and CNS drug discovery, we have developed a strategic framework to enhance probability of success by systematically tackling key challenges faced in CNS drug discovery and development, including human centric strategy, CNS drug delivery, translational disease model, and biomarker-integrated trial design. By leveraging cutting edge sciences/technologies and exceptional clinical resources, 4B Tech, along with academic and industrial partners, is advancing a pipeline for innovative medicines to validate their therapeutic potentials in the clinic. Our aspiration is to make a meaningful positive difference to patients suffering from CNS diseases.
