Study of LBH589 (Panobinostat) to Treat Malignant Brain Tumors

Stopped early · Phase 2

Conditions studied: Recurrent Malignant Gliomas

In brief

The drug LBH589 (panobinostat) is an experimental (investigational) drug that is being tested for recurrent (returning) malignant gliomas. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). It belongs to a new class of drugs called "histone deacetylase inhibitors." Histones are proteins located in the nucleus of cells that bind to DNA, the chemical that makes up genes. These proteins help control which genes are turned "on" and "off." Studies have shown that drugs like panobinostat (LBH589) may lead to tumor cell death.
