Recruiting PHASE3 Stroke

New treatment option for Stroke

Official title Effect of Butyphthalide on Cognitive Level Change After Cerebral Vascular Event-a Randomized Control Trial (Be-CLEVER)

ClinicalTrials.gov ID: NCT05976152

What this study is testing

What is dl-3-butylphthalide?

dl-3-butylphthalide is an investigational medicine, given as a pill taken by mouth, being studied as a potential treatment for stroke.

Also referred to as DL-3-n-butylphthalide (NBP).

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Post-stroke cognitive impairment (PSCI) refers to a clinical syndrome characterized by cognitive impairment that occurs after a stroke event and persists for at least 24 weeks. Due to the early recovery of conditions such as delirium and transient cognitive impairment after stroke, the diagnosis of PSCI often requires cognitive assessment at 12 to 24 weeks post-stroke to determine the severity of cognitive impairment.
  • Phase 3: a large, late-stage study
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
