Clinical development of panobinostat in classical Hodgkin's lymphoma.

Abstract

Deacetylase (DAC) inhibitors are promising new anticancer drugs that have complex mechanisms of action, including induction of cell-cycle arrest and apoptosis, inhibition of angiogenesis and induction of a favorable anti-tumor immune response. Panobinostat, a potent inhibitor of DAC 1-11 enzymatic activity, has demonstrated a significant in vitro antiproliferative activity against classical Hodgkin's lymphoma (cHL) cell lines in addition to a promising clinical activity in early Phase I studies in patients with relapsed cHL. In a recently completed large Phase II study in patients with relapsed cHL, panobinostat reduced tumor measurements in 74% of patients, including 23% partial and 4% complete remissions. In this article, we review the status of panobinostat drug development and compare its activity to those of other DAC inhibitors in patients with relapsed cHL. Future investigations should focus on designing rational combination regimens and identifying predictive markers that will assist in selecting patients who are likely to benefit from this novel therapy.
