Ghent ‘lama company’ ready to treat first corona patient

The Ghent biotech company Exevir receives 3 million euros in subsidies from Flanders and is ready to treat a first corona patient with its virus inhibitor.

After more than a year of work, the virus inhibitor from Exevir is ready in the refrigerators of three Belgian hospitals. It is still waiting for a suitable patient who meets all the criteria to be treated with the experimental drug.

The intention is to follow up 27 patients in a first study, but due to the relatively low number of hospital admissions, there is no evidence to quickly find patients who meet all the conditions. The study will measure Exevir’s effectiveness in hospitalized patients whose virus is relatively mild.



Our latest findings demonstrate the potential of our treatment to neutralize all variants in circulation.

In a second study, Exevir is targeting 250 patients. In the meantime, Exevir is also making all preparations to expand the study to include the UK and Italy, where the infection rates are rising rapidly.

Exevir, a spin-off of the Flemish Institute for Biotechnology, has already shown in petri dishes and in hamsters that its drug can neutralize the SARS-CoV-2 virus. After injection, the drug binds to a particle of the crown protein of the virus. The virus then loses its key to entering body cells, preventing it from multiplying.

The essence

  • Exevir developed a drug to neutralize the coronavirus in hospitalized patients. That drug would work with all variants in circulation.
  • Exevir is poised to test its product in humans for the first time.
  • The start-up has already collected 42 million euros in capital and is looking for another 100 million euros this year and next.


Exevir also showed that the drug (codenamed XVR011) can handle new variants, including the rapidly advancing delta variant, without any problems. “Our latest findings demonstrate the potential of our treatment to neutralize all variants in circulation. The drug shows the greatest potential in its class.”

Lama’s

Exevir gets its inspiration – just like Ablynx and Argenx – from the immune system in llamas. One of the advantages of llama antibodies is that they are very small and can penetrate more deeply into virus proteins. Exevir thus targets parts of the coronavirus that would otherwise be inaccessible.

With his drug, Exevir is building a second line of defense against the pandemic. While vaccines are being developed to boost the immune system, many companies are also working on virus inhibitors to cure the chances of survival in the hospital.



The delta variant is so contagious that it will continue to circulate. For the elderly whose immune systems are less powerful or for patients with underlying diseases, we will need treatments like ours.

There is a need for this because not everyone will be vaccinated and the existing vaccines do not offer 100 percent protection. ‘At the end of the day, perhaps a quarter of the European population will not be protected. The delta variant is so contagious that it will continue to circulate. For elderly people whose immune systems are less powerful or for patients with underlying diseases, we will need treatments like ours,” says CEO Torsten Mummenbrauer.

100 million

Last year, Exevir raised EUR 42 million in capital from, among others, UCB, and the search has begun for another EUR 100 million.

Exevir does not want to leave it at this one virus. It has a technology platform that can be widely deployed for other potential pandemic outbreaks or to fight infections such as influenza, which kill several hundred thousand people worldwide every year.

In order to realize its plans, the company has received 3 million euros in additional subsidies from the Flemish government. The management has also started the search for fresh capital. ‘The ambition is 100 million euros, spread over this and next year’, says Mummenbrauer.

Since its inception, the company has raised 42 million euros. UCB Ventures, Fund+, FPIM, SRIW, Noshaq and a few ‘Belgian family offices’, among others, put money on the table.
