Quisinostat is an orally bioavailable potent histone deacetylase inhibitor, specifically selected due to its sustained inhibition of HDAC1 in solid tumor tissues and prolonged period of half-elimination from tissues. Phase 2 clinical trials are ongoing in patients with platinum-resistant ovarian cancer and non-small cell lung cancer (NSCLC). Quisinostat is active in the treatment of patients with relapsed or refractory Sézary syndrome. The most common drug-related adverse events reported in this trial were: nausea, diarrhea, asthenia. Grade 3 adverse events were also reported: hypertension, lethargy and pruritus.
