About Istodax:

ISTODAX is a medication manufactured by multiple manufacturers and aligned to the J Code: J9319. ISTODAX is administered via the intravenous route of administration.

ISTODAX is a histone deacetalyse (HDAC) inhibitor that is commonly used to treat cutaneous T-cell lymphoma (CTCL). It is indicated for use in adult patients who have already received a systemic treatment for their CTCL. ISTODAX (J9319) works by causing a buildup of acetylated histones, compounds responsible for modulating gene expression. This causes cell cycle arrest and apoptosis in cancer cells. Patient assistance for this medication can be found through Bristol Meyers Squibb.
