About this study

Official title: An Open-label Pilot Study of Fecal Microbiota Transplant (FMT) to Induce Weight Loss in Obese Subjects

Obesity is associated with changes in the composition of the intestinal microbiota, and the obese microbiome appears to be more efficient in harvesting energy from the diet.

Fecal microbiota transplantation (FMT) represents a clinically feasible way to restore the gut microbial ecology, and has proven to be a breakthrough for the treatment of recurrent Clostridium difficile infection.

The therapy is generally well tolerated and appeared safe. No clinical studies have assessed the dosage of FMT in obese subjects.

Read the detailed description

Recently, accumulating evidence supports a role of the enteric microbiota in the pathogenesis of obesity-related insulin resistance. Obesity is associated with changes in the composition of the intestinal microbiota, and the obese microbiome appears to be more efficient in harvesting energy from the diet. Colonization of germ-free mice with an 'obese microbiota' results in a significantly greater increase in total body fat than colonization with a 'lean microbiota', suggesting gut microbiota as an additional contributing factor to the pathophysiology of obesity. Obese and lean phenotypes can also be induced in germ-free mice by transfer of fecal microbiota from human donors. These data have led to the use of microbiota therapeutics as a potential treatment for metabolic syndrome and obesity.

Fecal microbiota transplantation (FMT) represents a clinically feasible way to restore the gut microbial ecology, and has proven to be a breakthrough for the treatment of recurrent Clostridium difficile infection. Furthermore, clinical trials are being conducted to evaluate its use for other conditions including inflammatory bowel disease, irritable bowel syndrome, diabetes mellitus, non-alcoholic steatohepatitis and hepatic encephalopathy. Early results in human have shown that FMT from lean donor when transplanted into subjects with metabolic syndrome resulted in a significant improvement in insulin sensitivity and an increased in intestinal microbial diversity, including a distinct increase in butyrate-producing bacterial strains. The therapy is generally well tolerated and appeared safe. No clinical studies have assessed the dosage of FMT in obese subjects.
