Original description

Extensive research is being conducted in search of neuroprotective agents for possible use in the acute phase of stroke and agents that can be used for neurorepair in later stages of stroke. Several trials have been conducted and are in progress using different pharmacological agents, but none of the studies involve the stimulation of ETB receptors to treat cerebral ischemic stroke. Sovateltide (IRL-1620, PMZ-1620) has been effective in animal models of cerebral ischemic stroke. Its safety and tolerability have been demonstrated in a human phase I study with 7 subjects. Clinical phase II and III results indicate that sovateltide is a novel, first-in-class, highly effective drug candidate for treating cerebral ischemic stroke. Safety and significant efficacy in improving the National Institutes of Health Stroke Scale (NIHSS), Modified Rankin scale (mRS), and Barthel index (BI) obtained in phase II and III studies in patients with cerebral ischemic stroke in India are convincing and encouraged us to investigate its safety and efficacy in cerebral ischemic stroke patients in the United States. Therefore, the plan is to conduct a phase III clinical study to evaluate the safety and efficacy of sovateltide therapy along with standard of care in patients of acute ischemic stroke.Read full original descriptionShow less

A Multicentric, Randomized, Double-blind, Parallel, Placebo-controlled Phase III Study to Assess the Safety and Efficacy of Sovateltide in Patients With Acute Cerebral Ischemic Stroke.

Extensive research is being conducted in search of neuroprotective agents for possible use in the acute phase of stroke and agents that can be used for neurorepair in later stages of stroke. Several trials have been conducted and are in progress using different pharmacological agents, but none of the studies involve the stimulation of ETB receptors to treat cerebral ischemic stroke. Sovateltide (IRL-1620, PMZ-1620) has been effective in animal models of cerebral ischemic stroke. Its safety and tolerability have been demonstrated in a human phase I study with 7 subjects. Clinical phase II and III results indicate that sovateltide is a novel, first-in-class, highly effective drug candidate for treating cerebral ischemic stroke. Safety and significant efficacy in improving the National Institutes of Health Stroke Scale (NIHSS), Modified Rankin scale (mRS), and Barthel index (BI) obtained in phase II and III studies in patients with cerebral ischemic stroke in India are convincing and encouraged us to investigate its safety and efficacy in cerebral ischemic stroke patients in the United States. Therefore, the plan is to conduct a phase III clinical study to evaluate the safety and efficacy of sovateltide therapy along with standard of care in patients of acute ischemic stroke.

Inclusion: A patient will be eligible for inclusion in the study if he/she fulfills the following criteria:; Adult males or females aged 18 - 80 years of age; Consent obtained per national laws and regulations, and in accordance with the applicable ethics committee requirements prior to study procedures; A stroke is ischemic in origin that is diagnosed clinically and/or radiologically confirmed by Computed Tomography (CT) scan or diagnostic magnetic resonance imaging (MRI) prior to enrolment. No hemorrhage as proved by cerebral CT/MRI scan; Cerebral ischemic stroke patients presenting within 24 hours after the onset of symptoms with NIHSS score of ≥8 and <20, NIHSS Level of Consciousness (1A) score <2 at the time of screening. This includes cerebral ischemic stroke patients who completely recovered from earlier episodes before having a new or fresh stroke having a pre-stroke historical measure of mRS score of 0-2; The patient is <24 hours from the time of stroke onset when the first dose of sovateltide is administered. Time of onset is when symptoms began; for stroke that occurred during sleep, time of onset is when the patient was last seen or was self- reported to be normal; Reasonable expectation of availability to receive the full sovateltide/placebo course of therapy and to be available for subsequent follow-up visits.

Exclusion: Patients receiving endovascular therapy or is a candidate for any surgical intervention for the treatment of stroke, which may include but not limited to endovascular techniques; Concurrent participation in any other therapeutic clinical trial; Evidence of intracranial hemorrhage (intracerebral hematoma, intraventricular hemorrhage, subarachnoid hemorrhage (SAH), epidural hemorrhage, acute or chronic subdural hematoma (SDH)) on the baseline CT or MRI scan; Known medical history of neurological (other than current acute ischemic stroke) or psychiatric condition that, in the investigator's opinion, would confound the neurological and functional evaluations, lead to further deterioration of neurological status, or interfere with participation in this study; 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 sovateltide therapy would be contraindicated or might cause harm to the patient; A patient will not be eligible for inclusion in this study if they meet any of the following exclusion criteria:; Patients classified as comatose are defined as a patient who requires repeated stimulation to attend or is obtunded and requires strong or painful stimulation to make movements (NIHSS Level of Consciousness (1A) score ≥2); Known pregnancy and lactating women.
