Abstract
Sovateltide (Tycamzzi™), a highly selective endothelin-B receptor agonist and synthetic analog of endothelin-1, is being developed by Pharmazz, Inc. as a neural progenitor cell therapeutic agent for the treatment of acute cerebral ischemic stroke (ACIS), hypoxic-ischemic encephalopathy (HIE), spinal cord injuries and Alzheimer's disease. In May 2023, sovateltide was approved in India for the treatment of cerebral ischemic stroke within 24 h of stroke onset. This article summarizes the milestones in the development of sovateltide leading to this first approval for use in patients with ACIS.
