About us


Founded in 2017, Priavoid GmbH is headquartered in Jülich, near Düsseldorf, Germany.

Priavoid is a biopharmaceutical company focused on the development of novel therapies for patients with diseases of the Central Nervous System (CNS).

We develop novel therapies for the treatment of neurological diseases based on all-D-peptides. The most advanced drug in our pipeline is PRI-002, a Phase I clinical trial candidate for the treatment of Alzheimer’s disease. The treatment strategy of PRI-002 differs from conventional approaches in that the so-called “toxic oligomers” – that is the probable cause of the neurodegenerative disease – are eliminated in the presence of the drug candidate. The oral administration of PRI-002 leads to improved cognitive behavior in three different transgenic mouse models.


Priavoids aim is to become a leading Central Nervous System (CNS) development company.

Our global growth strategy has three elements, centered around developing innovative therapies for CNS disorders, with a particular focus on drugs for treatment of Alzheimer’s diseases.

1. Maximize PRI-002 commercial opportunity

We are working to maximize the opportunity for PRI-002, which as the first causal therapy to treat Alzheimer’s disease has the potential to improve the lives of patients around the world. After successfully completing a Phase I clinical trial, we plan to conduct a Phase II clinical trial.

2. Focus development resources on value-creation

To maximize the value of our pipeline, we are utilizing our development resources on our portfolio of CNS drugs. Developing CNS candidates matches best the company’s organizational resources, and allows us to generate substantial benefit for patients suffering from these diseases.

3. Out license or monetize non-core assets

Partnering is an important part of our overall strategy and we are actively talking to potential partners about our innovative pipeline of novel compounds, to ensure these compounds are profiting from the best expertise to bring them to market.
