One team, one mission

We are one team, driven by our ultimate purpose: to transform patients’ lives with therapies that restore health by negating the effects of genetic mutations.

Our Name

Hors Catégorie Bioscience

The HC in our name stands for hors catégorie (“beyond categorization”), a French term indicating the most difficult and prestigious hill climbs in a stage bicycle race such as the Tour de France.

Hors catégorie climbs represent a pinnacle of achievement in cycling, a challenge that can be met only with the right combination of talent, preparation and perseverance. We aspire to demonstrate those same qualities in our pursuit of new solutions for patients.

Success in hors catégorie climbs depends on exceptional power-to-weight ratio. Those riders who, like our engineered tRNAs, combine impressive power with a small, efficient form, dominate in hors catégorie climbs.

Our pillars of expertise

Starting with foundational research on tRNA engineering from the Ahern laboratory, we have built a robust and expanding discovery and drug development platform. We are especially distinguished by leadership in three key areas.

  • tRNA biology and drug development

    There are more than 450 tRNAs encoded in the human genome. To navigate this complex biology, our team combines extensive expertise in tRNA and protein translation with pharmacology, disease biology, and translational science—disciplines critical for successful bench-to-bedside transition.

  • Delivery

    We are developing cell-specific delivery vehicles with low immunogenicity and high durability. We have demonstrated liver-specific delivery using lipid nanoparticles, and are exploring multiple conjugation solutions for extra-hepatic diseases.

  • Computational analysis

    Rigorous data collection and analysis is vital to translating our understanding of tRNA biology and disease into breakthrough therapies for patients. Each choice we make — from engineering tRNAs, to delivery modality and dosing, to safety and pharmacokinetics — is informed by computational analysis and verified by experimental biology.

Leading the field

Our team comprises seasoned biopharmaceutical veterans with decades of experience in research and development; chemistry, manufacturing, and controls; and RNA and protein biochemistry.
