HDV targets therapeutics directly to the portal-hepatic region restoring liver-driven control of glucose and lipids—and raising the bar for metabolic care.

Metabolic Health Starts in the
Portal-Hepatic Region

The Portal-Hepatic Region is the body’s metabolic control center, integrating signals from insulin, GLP-1, and serotonin as they travel the portal-hepatic circulation. Together, these hormones regulate glucose and fat metabolism, nutrient storage, and appetite—linking the gut, liver, and brain in the physiologic control of energy balance.

Why Hepatocytes Matter

Hepatocytes are the liver’s functional core—utilizing and clearing insulin, GLP-1, and serotonin as they enter the liver through the portal vein. These specialized cells regulate how the body stores nutrients and controls whole-body blood glucose and fat metabolism. Today’s therapies struggle to reach hepatocytes and instead act in peripheral tissues. This divergence from natural physiology contributes to diminished efficacy, greater side effects, and limited durability.

Hepatocyte Directed Vesicle (HDV™) Platform

HDV™ enables access to this mechanism-rich environment, shifting drug action from peripheral tissues to where metabolism begins.
