Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This was a prospective, multicentric, randomized, double blind, parallel, saline controlled Phase II clinical study to compare the safety and efficacy of PMZ-1620 (INN: Sovateltide) therapy along with standard supportive care in patients of acute ischemic stroke.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

In PMZ group, 3 doses of PMZ-1620, at 0.3 μg/kg body weight will be administered as an intravenous bolus over 1 minute every 3 hours ± 1 hour on day 1, 3, and day 6 (total dose/day: 0.9 µg/kg body weight).

In control group, 3 doses of equal volume of normal saline will be administered as an IV bolus over 1 minutes every 3 hours ± 1 hour on day 1, 3 and day 6 post randomization.

In both treatment groups, subjects will be provided the best available standard of care.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Normal Saline (Dose: Equal volume) + Standard of care

Patients will receive the best available standard of care. In control group, 3 doses of equal volume of normal saline will be administered as an IV bolus over 1 minutes every 3 hours ± 1 hour on day 1, 3 and day 6 post randomization.

Group Type ACTIVE_COMPARATOR

Normal Saline along with standard treatment

Intervention Type DRUG

The arm is for active comparison for PMZ-1620 (sovateltide), an endothelin-B receptor agonist. PMZ-1620 has the potential to be a first-in-class neuronal progenitor cell therapeutics that is likely to promote quicker recovery and improve neurological outcome in cerebral ischemic stroke patients. Normal saline (vehicle) with standard treatment will be provided.
