Our goal

Da Volterra’s goal is to develop and commercialize innovative healthcare solutions to preserve the intestinal microbiome of patients worldwide and help prevent and cure life-threatening diseases.

As new insights into the human intestinal microbiome are fundamentally reshaping how we understand and treat a wide range of diseases, Da Volterra is a pioneer in understanding and harnessing the microbiome capacity to help prevent and cure diseases.

The company’s most advanced asset is DAV132, an oral product designed to be co-administered with any antibiotic, in order to protect patients from antibiotic-induced disruption of the intestinal microbiome.


The company was created by Professor Antoine Andremont whose life-long research was dedicated to antibiotic resistance and understanding the impact of antibiotics on the intestinal microbiome.


Company inception

Prof. Antoine Andremont creates Da Volterra based on concepts originating from his work on the impact of antibiotics on the intestinal microbiome and antibiotic resistance. Academic collaborations are set-up to explore early research work.


Early academic collaboration and technology patent filling

The first patents are granted on innovative approaches to protect the intestinal microbiome and spare patients from life-threatening bacterial infections. Further innovations are developed later on with new patent applications filed regularly by the R&D team.


Company structuration

The team is building up and takes foot in its facilities and laboratories of the rue de Charonne in Paris.
The management team is formed and 10 employees are recruited.


DAV132 proof of concept

The proof-of-concept of DAV132 is achieved in humans treated with antibiotics in a series of phase 1 clinical studies:
– No interaction with antibiotic efficacy
– Free antibiotic faecal concentrations decreased by 99%
– Very good protection of the microbiome diversity


DAV132 reaches 1st major
regulatory milestones

CE mark granted in Europe (ISO13485) and Pre-IND meeting with the FDA clears the development path as a drug in the USA.


Microbiome and Immuno-Oncology

First publications highlighting the role of microbiome and the impact of antibiotics on the efficacy of immune checkpoints inhibitors in cancer patients.


Completion of the phase 2 clinical trial evaluating DAV132 in patients

SHIELD is a European multicenter, randomized, parallel-groups study to evaluate the safety and efficacy/performance of DAV132 in hospitalized patients who receive fluoroquinolones for the treatment of acute infections.

It is the first phase 2 clinical trial assessing DAV132 safety and ability to protect the intestinal microbiome in patients.
