What this trial studies

This trial is a multicenter, randomized, double-blind, placebo-controlled exploratory clinical trial aimed at assessing the safety and tolerability of different doses of Edaravone Dexborneol concentrate for injection in patients diagnosed with cerebral hemorrhage. Participants must begin treatment within 6 to 24 hours of stroke onset, with specific criteria regarding the location and volume of the hematoma. The trial consists of two periods, focusing on dose escalation to determine the optimal safe dose for further evaluation. Safety assessments will be conducted after treatment to guide the continuation of the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with a clinical diagnosis of cerebral hemorrhage and specific criteria regarding hematoma volume and location.

Not a fit: Patients with severe comorbidities or those who do not meet the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients suffering from cerebral hemorrhage.

How similar studies have performed: Other studies have explored similar approaches, but the specific combination of Edaravone Dexborneol with conventional therapy in this context is relatively novel.
