About Us

CarboHyde is a private preclinical pharmaceutical start-up company specializing in the development of carbohydrate-based APIs. Our team consists of a small group of seasoned scientists with over 50 years of cumulative experience in the field of carbohydrate chemistry, analysis and pharmaceutical development.
The company’s core focus is neurodegenerative diseases, yet we also have other pre-clinical programs in various unmet medical indications.

Fully embracing the pharmaceutical development ecosystem, we utilize contract research organizations (CRO) and other companies focusing on CMC and clinical development to make our drug development process efficient.

CarboHyde’s management team has extensive experience in medicinal chemistry, marketing, and pharmaceutical development. In addition, CarboHyde is supported by experienced advisers, consultants, and carbohydrate veterans.

József Tóth MD, PhD – CEO of CarboHyde

While I was a med student at Semmelweis University, I was always fascinated by the complexity of physiological processes and how billions of molecules work together to maintain the homeostasis of the human body. It amazed me to look at the living cells under a microscope and to see their reactions after treating them with various compounds as it was a tiny little piece of this enormous puzzle but still drove me closer to understanding how living organisms work. So after graduation, I followed research in the field of cell physiology, where we developed biosensors to follow the dynamic changes of plasma membrane receptors, the bridges between the cell and the extracellular environment. I successfully defended my Ph.D. thesis in 2016, and meanwhile, I earned a Master of Healthcare Management degree in 2014. My interest in applied pharmacology led me to specialize in anesthesia and intensive care, in the fastest-growing field of medicine. As an anesthetist and intensive care specialist, during the last decade, I could look closely at how one single molecule, namely Sugammadex, a carbohydrate derivate revolutionized the safety of anesthesia. Here at CarboHyde, surrounded by world-class researchers, chemists, pharmacists, and engineers, we are committed to taking part in the next success story and being a key player in carbohydrate pharmacology.

CarboHyde, advisory board


Carbohydrate chemistry, the final frontier. These ubiquitous building blocks of life are still the most challenging biomolecules to manipulate due to their structural diversity and complexity. A realm where only the bravest creative chemists can go to deeply understand their biological importance, explore and embrace their therapeutic value.
From the discovery of the first carbohydrate antibiotic streptomycin, a widely used class of antibacterial aminoglycosides (tobramycin, gentamicin, netilmicin, or amikacin) was established; deoxy sugars (cladinose and desosamine) are essential constituents of the fascinating class of antibacterial/antifungal drugs known as macrolides (azithromycin, clarithromycin, erythromycin); amino sugars are key-constituent of nucleoside antibiotics such as puromycin or first-choice anthracycline chemotherapeutics such as doxorubicin.
The use of carbohydrates as API for the treatment of rare diseases is an emerging field with a worldwide consensus as demonstrated by the approval of miglustat (Gaucher disease) and by the orphan drug status exceptionally granted by the FDA to carbohydrates such as the iminosugar migalastat (Fabry disease) and the non-reducing sugar (2-hydroxypropyl)-β-cyclodextrin (Niemann–Pick type C).


Our vision is to become THE carbohydrate company, a creator of true value for the patients and partners via our experience in carbohydrates, with ultimate professionalism.

CarboHyde is advancing a pipeline of wholly-owned carbohydrate-based API candidates that address a number of diseases with high unmet needs or other novel applications.

CHD-101: an undisclosed rare genetic disease with unmet medical need; optimized next-generation carbohydrate-drug

CHD-111: undisclosed progressive neurodegenerative disease; optimized next-generation carbohydrate-drug

CHD-201: Alzheimer’s disease; a unique carbohydrate with superior pharmacokinetics designed for the purpose; proof-of-concept studies passed in various cellular and animal models

CHD-401: novel vaccine adjuvant; a tailor-made carbohydrate to dramatically boost local T-cell related immune response; efficiency is proven in different commercial vaccines

CHD-501: CarboHyde is developing carbohydrate-based nanoparticles to efficiently protect and deliver siRNA and other oligonucleotides to cells under ‘GENEGUT,’ a Horizon Europe-funded project (GA 101057491). The aim of GENEGUT is to develop the first oral RNA-based therapy for ileal Crohn’s Disease. The project is coordinated by the School of Pharmacy of University College Cork and made up of nine partners from eight European countries, including CarboHyde, who are all leading experts in their field.

The challenging task of CarboHyde is to synthesize amphiphilic cyclodextrins, which will be used to formulate nanoparticles containing the RNA cargo.
