Metabolic disease is a multi-organ pathology caused by insulin resistance which affects an estimated 1 billion people worldwide. Despite this high prevalence, the disease remains inadequately treated, with polypharmacy approaches managing the symptoms of the disease — such as hypertension, atherosclerosis, and high blood sugar — rather than addressing its underlying cause.
Recently, a new scientific understanding of metabolic disease has emerged that points to the central role of the small intestine. Fractyl’s pioneering research has revealed a mechanism by which to control this metabolic controller. Our therapeutic focus is on developing treatments that act on the duodenum to control metabolism broadly.
The duodenum is the first section of the small intestine. It’s the first point in the intestine where nutrient absorption and hormonal signaling begins, immediately after food passes through the stomach. The lining of the intestine is the body’s largest endocrine organ, continuously sensing for the presence and type of ingested food in the gut and sending neurohormonal signals to the brain and the rest of the body.
In healthy diets, nutrients are absorbed throughout the length of the intestine. Unhealthy diets, such as those high in fats and sugars, are more easily digested, frontloading more of the nutrient absorption to the duodenum.
The duodenum serves as a key regulator of metabolism by sending neurohormonal signals to the organs that regulate blood sugar and body weight.
Fractyl’s research has uncovered an important mechanism linking unhealthy diets to pathological changes in the duodenum and the development of metabolic diseases, including type 2 diabetes. When diets high in fats and sugars cause excessive nutrient absorption in the duodenum, the duodenum adapts by thickening its lining. A thickened lining causes the duodenum to absorb even more nutrients and inappropriately produce more signaling hormones, creating a cascade of events that lead to insulin resistance and weight gain.
Diets high in fat and sugar result in thickened lining Conversely, interventions on the duodenum may be able to reverse type 2 diabetes — an outcome which has already been clearly established thanks to research into the effects of bariatric surgeries. Certain bariatric surgeries that bypass the duodenum lead to immediate improvements in insulin resistance and blood sugar levels even before patients lose any weight. However, if nutrition is delivered to the duodenum again, the insulin resistance and high blood sugar return.
Fractyl has developed an approach called duodenal mucosal resurfacing (DMR) to reverse the abnormal thickening of the duodenal lining and control the duodenum’s impact on metabolism. Revita® DMR is the only therapeutic option designed to address the root cause of type 2 diabetes.
