Transforming protein degradation to create new medicines

A new class of oral, CNS penetrant protein degraders

COMPANY OVERVIEW

About Us

Kesmalea is developing a pipeline of novel therapeutics founded on the ability to transform large protein degraders into small molecules.

Targeted protein degradation (TPD) is an area of growing therapeutic investment with strong emerging clinical data. The most prominent class of protein degraders in development are bifunctional degraders. These are highly versatile and can be designed in a rational, modular way, but their large size results in poor drug-like characteristics that narrows their clinical viability.

Kesmalea’s SELFTAC® platform is a widely applicable solution to this “size problem”. We insert a reversible linker between the two main components of these large degraders, transforming them into small molecules that self-assemble into the bifunctional degrader at the appropriate location to fight disease. As small molecules, their oral bioavailability and ability to penetrate the central nervous system is much easier to achieve.

The SELFTAC platform was built on foundational scientific work by Harry Finch, PhD, the Company’s Founder & CSO, a noted medicinal chemist with an extensive career in both cutting-edge start-ups and large pharma. The SELFTAC technology was the basis for Kesmalea’s £25m Series A funding in 2022 co-led by Syncona Ltd and Oxford Science Enterprise.

Kesmalea’s pipeline reflects the broad opportunity of TPD in prevalent chronic diseases, with drug discovery currently underway in oncology and CNS. We are pursuing both in-house development and collaborating with other companies with complimentary technologies and capabilities.
