About Us

Nanna Therapeutics is a small-molecule focused therapeutics biotech subsidiary of Astellas, a global pharmaceutical company.

Based in Cambridge, UK, Nanna Therapeutics was acquired by Astellas in 2020 – and together with research partner, Mitobridge (acquired by Astellas in 2018) create the Mitobridge Division; a US- and UK-based research engine of Astellas (reporting to the Chief Scientific Officer). The Mitobridge Division works as part of the Astellas Primary Focus Mitochondria area of research.

Our Vision

Leveraging enabling platforms to develop transformational therapeutics via phenotypic screening and optimization approaches. We focus on early-stage, small-molecule drug discovery research in the area of mitochondrial & rare diseases. Our goal is to discover disease-modifying, transformative new medicines for illnesses with significant unmet medical needs.

Therapeutic Areas

We are addressing fundamental cellular processes to create medicines to treat various mitochondrial dysfunction-related diseases. With a strong focus on mitochondria, the energy source in every cell, we can target the fundamental causes of many diseases. Through this approach we are also addressing life-limiting mitochondrial diseases for which there are currently few or no effective therapies.

Our Approach

Healthy mitochondria are critical to normal cellular activities, as the cells’ power source. Mitochondrial dysfunction drives the pathogenesis of a wide variety of diseases, and as we age our cells produce less energy. We are focused on creating new options to combat target diseases by regulating mitochondria. We combine expertise in core biology areas of mitochondria and immune-modulation together with a unique patient cell-enabled phenotypic screening paradigm that enables closer association to the targeted diseases.
Distinct aspects of mitochondrial function (bioenergetics, dynamics, and cellular signalling) are well described and impairments in these activities contribute to disease pathogenesis – we utilise an integrated platform of assays and models to systematically evaluate disease-related changes in mitochondrial function in order to deliver new medicines.


 We work closely with wide-ranging external partners, including universities and academic institutions, centres of excellence for mitochondrial research, CROs, our Mitobridge colleagues in Cambridge, USA, and our Astellas colleagues in Japan and globally.

We actively seek technology and asset partnerships together with Astellas BD S&E (UK/EMEA) in Cambridge, UK.

Please contact us if you are interested in a partnership.


Our Team

We have an experienced, dynamic team of scientists and leaders focused on delivering innovative new medicines to patients.
