Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 45 to 90 years with acute ischemic stroke eligible for thrombolysis within 3 hours of symptom onset.

Probably not a fit

Patients with large extent early ischemic changes or any intracranial hemorrhage will not benefit from this study.

What this trial studies

This Phase 2b trial investigates the efficacy of NoNO-42 in patients experiencing acute ischemic stroke who are eligible for thrombolysis with or without endovascular thrombectomy. The study will enroll up to 600 participants aged 45 to 90 years within 3 hours of stroke onset, using a randomized, controlled design with a 1:1 allocation to either NoNO-42 or placebo. Participants will receive a single intravenous dose of the study drug or placebo, and outcomes will be assessed over a 90-day follow-up period. The trial aims to evaluate both the efficacy and safety of the treatment in this critical patient population.

Why it matters

Potential benefit: If successful, this treatment could significantly improve recovery outcomes for patients suffering from acute ischemic stroke.

How similar studies have gone: Other studies have shown promise in similar approaches, but this specific treatment is being evaluated in a novel context.
