a new source of energy

Established in 2012, Khondrion is focused on the development of innovative therapies for inherited mitochondrial diseases.

about Khondrion

Khondrion is a clinical-stage pharmaceutical company discovering and developing therapies targeting mitochondrial disease. The company is advancing its proprietary science through a wholly-owned clinical and preclinical small molecule pipeline of potential medicines.  

The company’s in-house discovery engine is using unique live-cell imaging technologies, patient-derived cell lines and predictive cell-based disease models to build a portfolio of promising compounds. Active discovery programmes are underway developing new therapies, biomarkers and new read-out technologies in the field of mitochondrial diseases.

To accelerate the discovery and development of its potential medicines for mitochondrial diseases, Khondrion collaborates with a global clinical and academic network and patient organisations internationally. Khondrion is headquartered in Nijmegen, The Netherlands.


Khondrion was founded by Professor Dr. Jan Smeitink who has devoted his entire career to the care of mitochondrial disease patients, to better understand the complexity of this disease and his life mission is to develop a treatment for these high impact, often early, fatal group of disorders.

Fully operational since 2012 and located in Nijmegen, The Netherlands, Khondrion focuses primarily on the development of innovative therapies for inherited mitochondrial diseases, including Leigh disease, MELAS (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes), Leber’s Hereditary Optic Neuropathy and other Respiratory Chain / Oxidative Phosphorylation disorders.
