Could a common antibiotic help brain bleed patients?
NCT ID NCT07305896
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if the antibiotic minocycline can improve recovery after a brain bleed (intracerebral hemorrhage). About 1,248 patients will either receive standard care or standard care plus minocycline for 7 days. Researchers will check their ability to function independently 180 days later to see if the drug helps.
