New preclinical experiments reported herein identified that low nanomolar plitidepsin concentrations potently inhibited the proliferation of JAK2V617F-mutated cell lines and lowered colony formation by CD34 cells of folks with MF, at the least in part by means of modulation of p27 levels. Cells of MF sufferers had drastically reduced p27 content, that had been modestly enhanced upon plitidepsin exposure. On these premise, an exploratory phase II trial evaluated plitidepsin 5 mgm2 3-h intravenous infusion administered on days 1 and 15 each 4 weeks (q4wk). Response rate (RR) in line with the International Functioning Group for Myelofibrosis Study and Treatment consensus criteria was 9.1 (95 CI, 0.21.3 ) in 11 evaluable sufferers through the initial trial stage. The single ALK5 Storage & Stability responder achieved a red cell transfusion independence and steady disease was reported in nine further individuals (81.8 ). Eight sufferers underwent a short-lasting improvement of splenomegaly. In conclusion, plitidepsin 5 mgm2 3-h infusion q4wk was well tolerated but had a modest activity in patients with main, post-polycythaemia vera or post-essential thrombocythaemia MF. Thus, this trial was prematurely terminated and we concluded that additional clinical trials with plitidepsin as single agent in MF are usually not warranted. Blood Cancer Journal (2015) five, e286; doi:ten.1038bcj.2015.five; published online 13 MarchINTRODUCTION Primary myelofibrosis (PMF) and post-polycythaemia vera (post-PV MF) or post-essential thrombocythaemia myelofibrosis (post-ET MF) comprise a heterogenous group of chronic myeloproliferative neoplasms with no curative therapeutic modality at present except for allogeneic stem cell transplantation.1 They are characterised by expansion of a clonal haematopoietic stem cell population leading to a bone marro.
