Givinostat (INN[1]) or gavinostat (originally ITF2357) is a histone deacetylase inhibitor with potential anti-inflammatory, anti-angiogenic, and antineoplastic activities.[2] It is a hydroxamate used in the form of its hydrochloride.

Givinostat is in numerous phase II clinical trials,[3] and has been granted orphan drug designation in the European Union for the treatment of systemic juvenile idiopathic arthritis[4] and polycythaemia vera.[5]

ITF2357 was discovered at Italfarmaco of Milan, Italy. It was patented in 1997 and first described in the scientific literature in 2005.[6][7]

Adverse effects

In clinical trials of givinostat as a salvage therapy for advanced Hodgkin's lymphoma, the most common adverse reactions were fatigue (seen in 50% of participants), mild diarrhea or abdominal pain (40% of participants), moderate thrombocytopenia (decreased platelet counts, seen in one third of patients), and mild leukopenia (a decrease in white blood cell levels, seen in 30% of patients). One-fifth of patients experienced prolongation of the QT interval, a measure of electrical conduction in the heart, severe enough to warrant temporary suspension of treatment.[8]

Mechanism of action

Givinostat inhibits class I and class II histone deacetylases (HDACs) and several pro-inflammatory cytokines. This reduces expression of tumour necrosis factor (TNF), interleukin 1α and β, and interleukin 6.[7]

It also has activity against cells expressing JAK(2V617F), a mutated form of the janus kinase 2 (JAK2) enzyme that is implicated in the pathophysiology of many myeloproliferative diseases, including polycythaemia vera.[9][10] In patients with polycythaemia, the reduction of mutant JAK2 concentrations by givinostat is believed to slow down the abnormal growth of erythrocytes and ameliorate the symptoms of the disease.[5]
