About Us


hC Bioscience is dedicated to improving the lives of patients with the development of first-in-class tRNA-based therapeutics targeting protein dysfunction. hC Bioscience’s innovative approach to precision protein editing has the potential to treat genetically-defined conditions which account for 10-15% of all human disease.



As the building blocks and machinery of life, proteins are made from long chains of specific amino acids coded by DNA.  Errors in the DNA code often lead to errors in proteins, resulting in dysfunction and many genetically-defined diseases.  Our team is addressing these diseases directly by creating first-in-class tRNA-based therapies that correct the proteins caused by many forms of DNA coding errors.



hC – hors catégorie means “beyond categorization”  

Hors catégorie is a French term used in stage bicycle races to designate a climb that is “beyond categorization”. The term was originally used for those mountain roads where cars were not expected to be able to climb. 

We will go where others have not with tRNA based therapeutics.
