the company

The French biotech company Meletios Therapeutics was created in April 2020 by a team of high level scientists and experienced biotech managers. The aim is to fulfill the urgent and large unmet medical need for antiviral molecules against current and emerging diseases.

One of our first drug candidate has confirmed its potential on in vitro and in vivo models by acting both on the virus SARS-CoV-2 and on infected cells. This molecule will now be developed and tested in order to fulfill the regulatory requirements and enter into clinical phase.

Several drug candidates from Meletios portfolio are currently being tested both in vitro and in vivo and will widen our range of antiviral molecules on different viruses. Some of these molecules have already been tested in clinic for other human pathologies, so they will have the two main advantages: a well-known safety profile and an accelerated development.

Meletios Therapeutics’ goal is to become a world leader in the fight against emerging viral infections by developing innovative broad-spectrum therapeutic solutions.


Visual Capitalist


As far back as we can remember, there has always been a real concern for human communities about epidemics, which have been incredibly devastating in the past. Today, even with scientific advances we are seeing a speeding up of the phenomenon. We are increasingly interconnected and we are pushing the boundaries of our environment further and further, yielding unknown viruses to come out into the open.

There is thus a real need to anticipate the emergence of new viruses that could lead to globalized epidemics such as COVID-19.


To tackle future emerging viruses, we need to implement everything possible to channel the epidemics. Vaccines and treatments are 2 complementary therapeutic strategies.

Vaccines are a key preventive tool but have the disadvantage of targeting a virus that needs to be already (well) known and is uncertain against possible variants. It can also take a long time to implement them.

An alternative is therefore needed for patients already ill to treat their symptoms and resolve the infection from the start of the epidemic. Depending on their mechanism of action, antiviral drugs can be effective against a wide range of viruses and are therefore an important hope for limiting the impact of pandemics.

A need for broad-spectrum antivirals to quickly save patientslives regardless of the viral strain causing the pandemic

We are facing an increasing number of pandemic situations

New viruses are to emerge with a lack of overlap between viruses



Vaccines are mostly efficient against one strain only

Implementation in the population takes long

Viral genome are small and evolve rapidly

It is sometimes impossible
to design a vaccine for a virus



The current antiviral armamentarium is not sufficient to face current and future epidemics

Broad spectrum antiviral could be used as soon as a viral pandemic is identified

Antivirals will be efficacious against a large panel of viruses

meletios R&D STRATEGY

We have developed three complementary approaches to fight viruses. Meletios is working closely with recognized experts to steer us in each direction.

The first angle consists in developing a broad-spectrum antiviral drug by targeting host mechanisms which are hijacked by viruses. In vitro and in vivo proofs of concept were obtained with repositioned small molecules.

The second approach directly targets the virus’ proteins by inhibiting viral replication with an innovative pharmacophore and the possibility of large-scale production.

The third approach is a disruptive technology that involves parasitizing the viral machinery with defective genomes to prevent it from producing new infectious virions.
