Cancer drug lowers brain vessel issues
A Swedish study has found that the drug dabrafenib, originally used to treat brain tumors in children, shows promising effectiveness in reducing cerebral cavernous vascular malformations—fragile blood collections that can cause brain hemorrhages. Experiments on mice demonstrated that the medication decreases the size of these malformations and helps stabilize the blood vessels, with similar improvements observed in cases involving the retina. This is achieved by targeting two cellular pathways involved in the development of these malformations. Currently, these findings are in the preclinical stage, and human studies are still needed to determine appropriate dosing and long-term safety before this approach could be considered an alternative to surgery in the future.
