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 the mechanism-rich portal-hepatic region, shifting drug action from
peripheral tissues to the liver, the control center of metabolism.

Advancing Next-Generation Therapies

HDV is a first-in-class platform that delivers drug actives to the portal-hepatic region with precision. HDV is safe and compatible with a wide range of active pharmaceutical ingredients. HDV offers a scalable and differentiated approach to developing the next generation of metabolic therapies.

Redefining What We Know About Hypoglycemia

OPTI-2 Phase 2b trial data demonstrate that targeting HDV-Insulin to the liver maintains glycemic control while reducing hypoglycemia, providing the first clinical evidence that tighter control and lower risk can coexist.
