CarboHyde appoints Tamas Sohajda as CEO of the company

CarboHyde, a pharmaceutical company specializing in carbohydrate chemistry and innovative carbohydrate applications, today announced the appointment of its new CEO Tamas Sohajda, replacing the founder and former CEO, József Tóth. The reasons for the decision are captured in József’s personal memorandum below.

Dear colleagues, friends, and valued partners,

Today, I am writing to share an important announcement that marks a significant turning point in my life’s journey. After an incredible adventure at the helm of our beloved biotech startup CarboHyde, I have made the decision to retire from my role as CEO. I am stepping down from this position but will stay in the company as Chief Medical Officer.

It has become clear that dedicating myself both to a full-time consultant position at Semmelweis University and, meanwhile, leading CarboHyde is simply not feasible at the same time, as the expansion and development of the company demand an increasing amount of time, effort, and focus. As a result, I have come to the difficult decision to retire from my position as CEO in order to ensure that the company continues to thrive and reach its full potential under new leadership.

Words cannot express the deep gratitude and immense pride I feel as I reflect upon the extraordinary experiences we have shared throughout this incredible voyage. It has been an honor and a privilege to work alongside such remarkable individuals who have inspired me every single day.

Additionally, I would like to take a moment to express my utmost confidence in the capabilities of our incoming CEO. Tamás Sohajda, a brilliant and accomplished leader, will undoubtedly bring a fresh perspective and a wealth of expertise to guide our company into its next phase of growth. I have had the pleasure of working closely with Tamás and have witnessed firsthand his exceptional leadership qualities and strategic acumen. His deep understanding of the biotech industry, combined with his visionary thinking, will be invaluable assets as we steer CarboHyde toward new horizons. I have no doubt that Tamás will continue to drive our company towards even greater success.

In conclusion, I would like to express my deepest gratitude to each and every one of you.

With warm regards,

József Tóth

LSU Health Shreveport and CarboHyde collaborate to develop cyclodextrins for restoring sulfide in various disease conditions

Dr. Chris Kevil’s laboratory at LSU Health Shreveport (LSUHS) has discovered that a clinically approved cyclodextrin-based drug called Sugammadex can act as a hydrogen sulfide donor that restores vasoactive hydrogen. This innovation has already gone through initial in vivo testing with promising results.

To take the next leap in development, LSUHS and CarboHyde will start a multiple-staged collaboration project to assess the effects of various cyclodextrins as potential hydrogen sulfide (H2S) donors in methamphetamine-mediated vascular diseases and for various other cardiovascular diseases. Methamphetamine users face a significantly higher risk for cardiovascular disorders, according to a major study published by the Journal of the American Heart Association earlier this year. The Kevil lab has also recently published that chronic methamphetamine use causes cardiovascular dysfunction due to reduced hydrogen sulfide. This poses an additional threat and possible treatment approach for those who use or have already stopped using meth.

LSU Health Shreveport and the Kevil laboratory will focus on comparing the effects of different cyclodextrin derivatives in blood sulfide levels and test the compounds in vitro and in different animal models. CarboHyde’s expertise will be used to select and customize this project’s best-working cyclodextrin derivatives.

“This is exactly the type of research our minds are formed around. We simply admire innovative ideas and out-of-the-box applications of cyclodextrins and other carbohydrates. We keep looking for opportunities to add our knowledge to drive such studies forward. I am sure our collaboration with LSU Health Shreveport and Dr. Kevil will be mutually rewarding and may open novel insights in the application of cyclodextrins in cardiovascular diseases,” said CarboHyde’s CEO József Tóth about this upcoming collaboration.

“Collaboration with carbohydrate expertise at CarboHyde represents a unique opportunity to develop innovative molecules and modalities to treat methamphetamine and other cardiovascular diseases, said Dr. Chris Kevil.

CarboHyde participates in an innovative EU-funded research project to change the treatment paradigm for Crohn’s Disease patients with new RNA-based therapy

GENEGUT, a research project funded by Horizon Europe, is to develop the first oral RNA-based therapy for ileal Crohn’s Disease (CD) – a chronic inflammatory disease of the intestine. The work is set to start on 1st October 2022 and last for four years. The consortium is made up of nine partners from eight European countries, who are all leading experts in their field. CarboHyde will play a crucial role by kick-starting the project by developing custom-made cyclodextrin derivatives, which will help to deliver their RNA cargo to the small intestine.

Addressing the major medical need of Crohn’s Disease

Crohn’s disease (CD), one of the two major disorders under the umbrella term of IBD (Inflammatory Bowel Disease), is a highly prevalent and high-burden chronic inflammatory condition of the gastrointestinal tract (GIT). With up to 3 million people affected in Europe alone, the chronic disease has an accelerating incidence – leading to health costs of over 5 billion euros per year. Most significantly, however, there is no satisfactory treatment.

Role of CarboHyde

The challenging task of CarboHyde will be synthesizing amphiphilic cyclodextrins, which will be used to formulate nanoparticles containing the RNA cargo. CarboHyde will synthesize a library of amphiphilic cyclodextrins, including ones with different excipients, like polyethylene glycol or lipids. Chemically different variations of these excipients will be studied to select the best-performing ones. Nanoparticle formulations with the best working amphiphilic cyclodextrins will be tested to withstand the intestinal environment in different in vivo and in vitro models.

CarboHyde hired a Ph.D. student, Kristof Felegyi, to help the project progress.

Bringing together a multidisciplinary, European network

The expertise required to achieve this ambitious aim is as diverse as the nine partners from eight European countries that will collaborate in GENEGUT.

The project, coordinated by the School of Pharmacy of University College Cork, brings together the European Federation of Crohn’s & Ulcerative Colitis Associations with renowned researchers, expert clinical scientists, SMEs, and large pharma companies with expertise and patented technologies in global proteomics, nanotechnologies, cyclodextrin synthesis, multicellular models, drug delivery systems and production as well as innovation management, stakeholder involvement, and science communication.

A library of novel biomaterials will be synthesized and used to formulate nanoparticles containing therapeutic RNA (siRNA and mRNA). A quality-by-design approach will be applied to develop the nanoparticles for filling into capsules. The resulting nanoparticles will be assessed for safety and efficacy, including the mechanism of action, in a range of advanced in vitro and in vivo models of intestinal inflammation. The clinician, with expertise in diagnosing and treating CD patients based in UCC, will support and guide the overall project ensuring clinical relevance and providing advice on coherent plans for early clinical trials and regulatory submission, thus enabling rapid availability for patients.

Follow the progress of GENEGUT at and on Twitter and LinkedIn @GENEGUT_EU to learn about the project’s steps toward a better cure for Crohn’s Disease.

What is the story of a pharma startupper?

To better understand the place and the goals of CarboHyde, a private preclinical pharma start-up from the EU, a short interview was performed with József Tóth, Ph.D., Founder, and CEO of CarboHyde.

What’s your story, and how did you become an innovator in healthcare?

During the years I spent at Semmelweis University as a med student, all my favorite subjects originated from cell biology. I eagerly awaited physiology lectures where the professors explained how the signaling pathways and living cells work and how they act together to form organs and the whole human body. Then later, during pharmacology courses, I was again fascinated to see how we can sometimes treat pathophysiological conditions by giving only one single molecule acting on one receptor. After finishing the Ph.D., my interest in applied pharmacology led me to specialize in anesthesia and intensive care, one of the fastest-growing fields of medicine. As an anesthetist and intensive care specialist, I could look closely at how one single molecule, Sugammadex, a carbohydrate derivate, revolutionized anesthesia safety.

Meanwhile, I was always interested in entrepreneurship and how a dedicated group of people can bring a new idea to the market. This process might look very easy to anyone watching popular start-up TV shows, but now I can tell you the reality cannot be further away from the truth. So we established a company, and now here at CarboHyde, surrounded by world-class researchers, chemists, pharmacists, and engineers, I feel fortunate to have the opportunity to combine these two interests of mine. It is a lovely, rewarding, and challenging journey.

József Tóth

Can you tell me a bit about your company, CarboHyde?

CarboHyde is a pharma start-up developing carbohydrate-based APIs for different target indications and other innovative applications like gene delivery or using them in vaccines. We founded CarboHyde not long ago, but the senior colleagues have worked together in this field for 10+ years. We also see other companies with similar interests as an ecosystem and support them with our knowledge in this field as a contract research organization.

As a CRO in the pharma industry, we only focus on the most complex synthetic chemistry issues our fellow innovators face with their carbohydrate or cyclodextrin-based drug development programs.

Our main aim is to develop our carbohydrate-based APIs, focusing on rare diseases, neurodegenerative CNS indications, and an RNA delivery platform. We are continuously looking for partners to collaborate on developing new therapeutic solutions in this field. So if any of our readers are one of them, they shouldn’t hesitate to contact us.

What I would like to highlight for the readers is my personal belief in the importance of the right company culture, mainly because our innovation-focused company is based on our colleagues’ exceptional brain power. So we build a very flat, administration-free culture, where we spearhead values like love of work, autonomy, freedom, results orientation, and responsibility. Our internal processes are transparent, and everyone completely understands our mission and what it takes to get there, then embraces the responsibility to make the right decisions. And we trust our people to make the right ones.


And why carbohydrates? What is so interesting in these molecule families?

Because my previous supervisor deals with lipids, my sister researches proteins, and my brother-in-law is an expert on nucleic acids, so that remains for me (smiles). Of course, that’s just a joke. I think people underestimate the role of carbohydrates in physiological processes and simplify them as only energy sources or structural molecules, but the reality could not be farther from that. Due to their structural diversity and complexity, I believe these ubiquitous building blocks of life are one of the most challenging biomolecules to manipulate. There are widely used carbohydrate-based drug families on the market, like deoxy sugars or amino sugars. Yet, carbohydrate-based API development is still a fast-growing area, including particular types of carbohydrates to treat rare diseases, like Niemann–Pick type C or Fabry disease. We are fond of these compounds, enjoy the challenge it takes to work with them, and believe that there is still a lot to learn in this area. Learning and evolving are our daily feeds.

What are the company’s short and longer-term goals?

Before answering your question, I want to highlight how proud I am of the results we have achieved this year already. It is essential to talk about the future, but it is equally important to look back and be proud of what we have already achieved – for me, this provides a source of energy, like my morning coffee with a high dose of carbohydrates. So this year, we have already managed to attract some internationally renowned scientists into the team, expand our pipeline program, and successfully apply for an EU grant. I believe these are great results.

But as a real startupper, I am ready to talk about our plans for hours (smiles). The shorter version is that our long-term goal is to hold 5+ patent families for different compounds, sponsor early-stage clinical trials and be a key-opinion leader in carbohydrate chemistry and drug development.

In the next 2-3 years, we will grow in size, strengthen our CRO arm and start focusing on our pipeline program. In addition, we have already been developing specific capabilities in-house, which we outsource at the moment – like carbohydrate analytics, which requires unique expertise.

As a pharma startupper, what advice do you have for others just starting in this space?

First of all, do not underestimate the work ahead. Several excellent books on the market can give helpful advice on how to treat the expected difficulties; I read a lot of them and enjoyed them. But no matter how many books you read about those topics, new and new unexpected challenges will come across, and one person alone cannot deal with all of them. So let’s find competent people, experts in their fields, who you can get along with as human beings, and who strongly believe in your projects. If you can gather people, you can trust and focus on each other’s strengths and enhance them, and you can handle these challenges together, sooner or later. And when you feel exhausted, you should know and practice where you can have extra energy – if it is your morning coffee with three spoons of carbohydrates or pursuing your hobby; it doesn’t matter.
