  6. Concurrent participation in any other therapeutic clinical trial.
  7. Evidence of any other major life-threatening or serious medical condition that would prevent completion of the study protocol, impair the assessment of outcome, or in which PMZ-1620 therapy would be contraindicated or might cause harm to the patient.

5. Study Description

Brief Summary
In the present prospective, multicentric, randomized, double-blind, parallel, saline-controlled phase II clinical study; the investigators plan to evaluate the efficacy of sovateltide (IRL-1620 or PMZ-1620) therapy along with standard supportive care in patients of acute ischemic stroke.
Detailed Description
The peptide Sovateltide (IRL-1620) is a highly selective ETB receptor agonist. There are hidden stem cells in the brain, which becomes active following injury to the brain. Intravenous administration of PMZ-1620 (sovateltide) augments the activity of neuronal progenitor cells in the brain to repair the damage by formation of new mature neurons and blood vessels. In addition, PMZ-1620 has anti-apoptotic activity and also increases cerebral blood flow when administered following ischemia. It was discovered that in rat model of ischemic stroke, sovateltide, significantly improved survival, reduces neurological and motor function deficit while effectively decreasing infarct volume, edema and oxidative stress. The convincing results of preclinical efficacy studies of Sovateltide in ischemic stroke and its safety affirmation from phase I and phase II clinical studies encouraged us to investigate its efficacy in human patients of ischemic stroke. In the present prospective, multicentric, randomized, double-blind, parallel, saline-controlled phase II clinical study; the investigators plan to evaluate the efficacy of Sovateltide therapy along with standard supportive care in patients of acute ischemic stroke.
