Description: Panobinostat, also known as NVP LBH-589 or LBH-589, is a cinnamic hydroxamic acid analogue with potential antineoplastic activity. Panobinostat selectively inhibits histone deacetylase (HDAC), inducing hyperacetylation of core histone proteins, which may result in modulation of cell cycle protein expression, cell cycle arrest in the G2/M phase and apoptosis. In addition, this agent appears to modulate the expression of angiogenesis-related genes, such as hypoxia-inducible factor-1alpha (HIF-1a) and vascular endothelial growth factor (VEGF), thus impairing endothelial cell chemotaxis and invasion. On 2/23/2015, it received FDA accelerated approval for use in patients with multiple myeloma who had received at least 2 previous treatments, including bortezomib and an immunomodulatory agent.

Additional Information

Panobinostat has been found to synergistically act with sirolimus to kill pancreatic cancer cells in the laboratory in a Mayo Clinic study. In the study, investigators found that this combination destroyed up to 65 percent of cultured pancreatic tumor cells. The finding is significant because the three cell lines studies were all resistant to the effects of chemotherapy – as are many pancreatic tumors. see
