Oral panobinostat (Farydak®), a potent nonselective histone deacetylase inhibitor, is approved in several countries for use in combination with bortezomib and dexamethasone in patients with multiple myeloma (MM) [USA] or relapsed and/or refractory MM (EU) who have received at least two prior treatment regimens, including bortezomib and an immunomodulatory drug (IMiD). In a pivotal phase III trial (PANORAMA 1) in patients with relapsed or relapsed and refractory MM who had received one to three previous lines of therapy, progression-free survival (PFS) was significantly prolonged with panobinostat plus bortezomib and dexamethasone compared with placebo plus bortezomib and dexamethasone. ⋯ Panobinostat plus bortezomib and dexamethasone had a generally manageable tolerability profile, with the most frequent grade 3-4 adverse events being myelosuppression, diarrhoea, asthenia or fatigue, peripheral neuropathy and pneumonia. Thus, panobinostat, in combination with bortezomib and dexamethasone, is a useful addition to the available treatment options for patients with relapsed or refractory MM.
