Protecting now from what comes next

The outbreak of COVID-19 caught the world off guard and severely constrained people's ability to live their lives to the fullest. Responses have been non-personal and broad (such as social distancing) or focused medical approaches targeting specific strains (such as vaccines). And while these solutions are crucial and these vaccines were developed at unprecedented speed, all responses are reactive.

What the world needs is a proactive approach. Nature harbors millions of unknown viruses and with virus mutations in humans, new infections are a given. However, we don’t know which one will strike next. The current reactive approach does not prepare us for these future threats.

It’s time for a new approach.

our new Approach

Leyden Labs’ proactive approach protects against a broad range of viruses

To protect from what comes next, we need to act proactively and be ready for a broad range of viruses. At Leyden Labs, we expand the armamentarium of available tools by developing our platform and products with three innovative concepts:

Targeting the commonalities of viruses

The millions of unknown viruses harbored in nature can be grouped in a few dozen of viral families. By targeting the commonalities of these families, we can develop protection against entire virus families at once, including the unknown variants. Our focus is on respiratory viruses like influenza and coronaviruses, which are most likely to cause pandemics because they are transmitted through the air.

Attacking viruses where they attack us

Through our platform, we are developing nasal sprays that provide immediate protection because they attack viruses where they attack us – in our nasal passages – keeping people safe from catching infections and preventing people from spreading them to others.

Providing protection independent of people’s immune system

Through our nasal sprays we deliver antibodies in the mucosa of the nasal passages that provide the user instant protection. It does not rely on the defense of a person’s own immune system and can therefore also effectively support population groups at risk, such as elderly and immunocompromised people.

Leyden Labs’ product candidates

We are working toward accessible, self-administrable products, so people can take control and live their lives to the fullest by protecting themselves against catching infections and preventing transmission to others. In January 2022, we announced that we have an exclusive license to develop and commercialize CR9114, a pan-influenza antibody protecting against influenza A and B. We are working hard to develop our PanFlu product candidate and advance it into the clinic.

We challenge limits

The city of Leiden (The Netherlands) inspired our name. For centuries, Leiden is known for unconventional thinking, the freedom to express this openly and scientific breakthroughs such as the first publications of Galileo’s famous Discorsi.

Our team of energetic, experienced and curious people is ready to go beyond to accomplish our mission. We strive for a fantastic life for all people. We aim for the highest, think unconventionally and focus relentlessly on delivering the impossible. In our team trust, integrity and inclusiveness are a given.

Our team

Meet our fantastic team. Together, we work towards our mission of freeing you from viruses.
