Protection of the Human Gut Microbiome From Antibiotics

A clinical trial demonstrated that DAV132, a product containing activated charcoal, significantly reduces the exposure of the human gut microbiome to the antibiotic moxifloxacin (MXF) without affecting its plasma pharmacokinetics. The study, involving healthy volunteers, showed that DAV132 could protect the intestinal microbiota's richness and composition from the adverse effects of MXF, suggesting its potential to mitigate the long-term consequences of antibiotic treatments.

Methods

DAV132, containing activated charcoal, was administered to healthy volunteers alongside moxifloxacin (MXF) to assess its protective effects on the gut microbiome. The study was a randomized, controlled trial conducted in compliance with Good Clinical Practice and the Declaration of Helsinki.

Results

  • MXF Pharmacokinetics: DAV132 reduced fecal MXF concentrations by over 99% without significantly affecting plasma levels, indicating targeted action in the gut.
  • Microbiome Protection: The richness and composition of the intestinal microbiota were largely preserved in volunteers receiving DAV132 with MXF, compared to those receiving MXF alone.
  • Safety: DAV132 was well tolerated, with no serious adverse effects reported, and did not interfere with the systemic therapeutic effects of MXF.
  • Broad Antibiotic Adsorption: DAV132's activated charcoal effectively adsorbed a wide range of antibiotics in ex vivo conditions, suggesting its potential applicability beyond MXF.

Discussion

The study highlights DAV132's potential as a breakthrough product for protecting the gut microbiome from the detrimental effects of antibiotics. Its ability to adsorb various antibiotics without affecting their systemic efficacy positions DAV132 as a promising candidate for further clinical evaluation to prevent antibiotic-associated dysbiosis and its long-term consequences.
