PerioTrap is a clinical stage Biotech company that aims to eradicate the root cause of periodontitis

Periodontitis is an inflammation of the gums mainly caused by a microbiotic shift towards pathogenic bacteria

It affects nearly 20 - 50% of the global population and is associated with a range of co-morbitities like diabetes or Alzheimer’s disease.

Current treatments involve painful removal of the whole biofilm followed by daily disinfection or antibiotics that keep disrupting the natural biofilm. Therefore patients loose biofilm homeostasis incl. beneficial bacteria with its metabolic and immunologic support and are more prone to recurrent infections.

We‘ve developed an innovative anti-infective drug that is capable of targeting only the disease causing pathogens and therefore represents an effective alternative to classic broad spectrum antibiotics. Protecting the commensal bacteria should encourage a shift towards a natural microbiome, thus preventing the reoccurrence of the disease.

The key element of this strategy is an enzyme called glutaminyl cyclase (QC) type II, which is exclusively present within pathogenic bacteria of the oral biofilm where Porphyromonas gingivalis is the main catalyst of the disease.

Our team and all of the founders possess many years of experience in drug development with a long-lasting history in a biotech environment and with additional background in one of the largest organizations for applied research worldwide. The company’s team combine competences in the field of medicinal chemistry and compound characterization, microbiology and management/business development. This is completed by the strong support of the additional founders with their experiences that includes biochemistry, target validation, pharmacology and drug development. The collectively track record includes the successful development of several drug development projects in the area of small molecules. Some hallmarks are the development of DP4 inhibitors as antidiabetics, the development of a completely novel pharmacological approach currently in clinical development for the treatment of Alzheimer's disease and the development of a new approach for the treatment of fibrosis caused diseases (non-clinical stage).
