A shift of paradigm in combating the silent pandemic.

Antimicrobial resistance –
a silent pandemic

It is estimated that by 2050, more people will die due to antimicrobial resistance than from cancer. The pipeline for novel treatment mechanisms is extremely thin. We at PathoBlock aim to introduce an innovative way to fight pathogens. Our lead product focuses on one of the most critical bacteria: Pseudomonas aeruginosa.

The bacterium
Pseudomonas aeruginosa

P. aeruginosa is one of the top three candidates on the WHO list of multidrug-resistant bacteria, which cause a serious healthcare challenge. So far, there are no realistic treatment options for antibiotic-resistant P. aeruginosa.


of hospital infections
are P. aeruginosa infections, making it the most common hospital acquired infection.


health care costs
can be directly attributed to P. aeruginosa infections in the DACH region only.


WHO warning
As ~15% of P. aeruginosa are already multidrug-resistant.

The PathoBlock approach

Not just another antibiotic

Instead of developing more and more antibiotics, to which resistance can be acquired, we developed a novel treatment mechanism that prevents infections early on. It thereby also prevents the development of resistance combined with less side effects, which has the potential to sustainably fight bacteria.


Unlike traditional antibiotics, our approach blocks the pathogenicity of bacteria without directly killing them. This pathoblocking prevents bacteria from harming their host. Disarmed and unable to infect human cells, the bacteria are removed from the body.

A sustainable contribution to AMR

Bacteria are rapidly gaining resistances against existing antibiotics (antimicrobial resistance). PathoBlock has demonstrated success where standard antibiotics failed. In addition, no signs of resistance against the PathoBlock approach itself could be observed.

No signs of toxicity

Often, traditional antibiotics have toxic side effects. PathoBlock does not cause toxicities because it consists of naturally occurring molecules that are specific to the target pathogen and do not harm the microbiome.

Robust chemical structure

The PathoBlock molecules used for inhibition are chemically stable and easy to store, which is especially relevant for 3rd world countries.
