Mikrobiomik is a biopharmaceutical company born for the research, development, production and commercialization of biologic medicines based on the human microbiome.

At Mikrobiomik we are developing a new generation of biologic medicines based on the human microbiome, focused on serious diseases, currently with no therapeutic alternative.

Our first investigational biological drug, MBK-01, aimed at the treatment of intestinal infection by Clostridioides difficile, has announced the closure of the phase III clinical trial, and patient recruitment has been completed in November 2023. The regulatory dossier will be presented to the EMA (European Medicines Agency) in 2024, via a centralized channel and its commercialization is expected during the first half of 2025.


Saving lives by leading the research and development of biologic medicines based on the human microbiome.


Mikrobiomik aims to be the first company worldwide to launch in the EU the first gut microbiota-based biologic medicine, FSPIM (Full Spectrum Purified Intestinal Microbiota), MBK-01, in an innovative freeze-dried gut microbiota capsule format for oral administration.



Each member of the team is committed to find therapeutic alternatives for life-threatening diseases, always from the perspective of solutions based on the human microbiome.



We plan to lead the paradigm shift of commercializing the first gut microbiota-based biologic medicine in Europe.



Research is part of our DNA, part of our culture. We spend a large part of our resources looking for new indications, with the aim of feeding our biologic medicine pipeline.



We are committed to excellence in all our processes. We produce under GMP (Good Manufacturing Practices), implement rigorous quality controls and select our donors meticulously.



Mikrobiomik is formed by a team of expert and multidisciplinary professionals, mostly composed of highly qualified women. Always focused on being the first company worldwide to commercialize in the EU, the first biologic medicine based on fecal microbiota, in the indication of Clostridium difficile.

“Being part of Mikrobiomik means breathing innovation and development.”
