Summary

This study tests a drug called sovateltide in 160 people who have had an ischemic stroke (a stroke caused by a blood clot). The goal is to see if the drug helps patients recover better and is safe. Participants receive either the drug or a placebo within 24 hours of their stroke, and researchers track their recovery over time using standard disability scales.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Sovateltide (also called IRL-1620, PMZ 1620, Tycamzzi, Tyvalzi)
What this could lead to
If it works, this could provide a new treatment to help people recover better after an ischemic stroke, potentially reducing long-term disability.
What could go wrong
This is a relatively small Phase IV trial, and previous results may not hold up. The drug is still experimental, and side effects or lack of benefit are possible.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult males or females aged 18 years through 78 years (have not had their 79th birthday) * Patient or Legally Acceptable Representative (LAR) willing to give informed consent before study procedure. * Stroke is ischemic in origin and radiologically confirmed Computed Tomography (CT) scan or diagnostic magnetic resonance imaging (MRI) before enrolment. No hemorrhage as proved by cerebral CT/MRI scan. * Cerebral ischemic stroke patients presenting within 24 hours after onset of symptoms with mRS score of 3-4 (pre-stroke mRS score of 0 or 1) and NIHSS score \>5 (NIHSS Level of Consciousness (1A) score must be \< 2). This includes cerebral ischemic stroke patients who completely recovered from earlier episodes before having a new or fresh stroke. * The patient is \<24 hours from the time of stroke onset when the first dose of Sovateltide therapy 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 course of therapy and to be available for subsequent follow-up visits. Exclusion Criteria: * 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. * 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). * Evidence of intracranial hemorrhage (intracerebral hematoma, intraventricular hemorrhage, subarachnoid hemorrhage, epidural hemorrhage, an acute or chronic subdural hematoma on the baseline CT or MRI scan 4. Known pregnancy. * Confounding pre-existing neurological or psychiatric disease. * Concurrent participation in any other therapeutic clinical trial. * 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.
