Vorinostat shows anti-cancer activity in recurrent gliomas
...inostat is the first FDA approved oral anti-cancer agent
that inhibits an enzyme, histone deacetylase, that is closely associated with DNA in cells. By inhibiting the deacetylation of histones -- proteins that help organize the structure of DNA -- vorinostat alters the expression of several important genes...

VEGF Trap shows activity in patients with advanced ovarian cancer
...EGF Trap is administered intravenously as a single agent
in one of two dose levels. It works by blocking the development of new blood vessels to the tumor (angiogenesis) which stops tumor growth and the spread of cancer to other parts of the body (metastasis). It can also result in tumor shrinkage. VEGF Tr...
