Brief summary

The purpose of this study is to test a new drug called AUY922. AUY922 is not FDA-approved. AUY922 is a new kind of drug that attacks a protein called HSP90. HSP90 is found in both normal and cancer cells, but the investigators think it is more important in cancer cells. This study will see if AUY922 helps people with myelofibrosis, essential thrombocythemia and polycythemia vera. This study will also see if AUY922 is safe in people with myelofibrosis, essential thrombocythemia and polycythemia vera. It will find out what effects, good and/or bad, AUY922 has on the patient and the disease. The researchers hope that this study will help them to find better treatments for primary myelofibrosis, essential thrombocythemia and polycythemia vera.

Interventions

DRUGAUY922

AUY922 will be administered as an intravenous infusion over 60 minutes, on a once weekly schedule. A cycle on study will be defined as 28 days. The dose to be studied are 70 mg/m2 and 55 mg/m2 if DLTs are identified in the first 3-6 patients. The same schedule of administration will be used for all patients in this trial.

Inclusion criteria

* Eligible patients must have myeloproliferative neoplasms, specifically, primary myelofibrosis (PMF), post polycythemia vera myelofibrosis (post-PV MF), post essential thrombocythemia myelofibrosis (post-ET MF), and PV/ET that are refractory to hydroxyurea, phlebotomy and anagrelide or not a candidate for standard therapies. * ≥ 18 years of age * ECOG performance status of 0-2 * Acceptable pre-study organ function during screening as defined as: Hematologic: * Absolute Neutrophil Count (ANC) ≥1.5x109/L * Hemoglobin (Hgb) ≥ 8 g/dl (may be supported with transfusion) * Platelets (plt) ≥50x10\^9/L Biochemistry: * Potassium within normal limits * Total calcium (corrected for serum albumin) and phosphorus within normal limits * Magnesium above LLN or correctable with supplements Liver and Kidney Functions * AST/SGOT and ALT/SGPT ≤ 1.5 x Upper Limit of Normal (ULN) if AP \> 2.5 X ULN * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 * Serum bilirubin ≤ 1.5 x ULN (Unless attributable to Gilbert's disease) * Serum creatinine ≤ 1.5 x ULN or 24-hour clearance ≥ 50 ml/min * Negative serum pregnancy test. The serum pregnancy test must be obtained prior to the first administration of AUY922 (≤ 72 hours prior to dosing) in all pre-menopausal women and women \<2 years after the onset of menopause * Patients who previously received JAK2 inhibitors will be eligible as long as they have been off the drug for more than 4 weeks. * Ability to understand and willingness to sign a written informed consent document.

Exclusion criteria

* Requiring ongoing therapy with either G- or GM-CSF, or long-acting versions of these molecules * Active medical condition such as infection or cancer that is actively requiring treatment. * Unresolved diarrhea ≥ CTCAE (v4.02) grade 1 * Prior anti-neoplastic treatment with any HSP90 or HDAC inhibitor compound * Patients who have undergone any major surgery ≤ 2 weeks prior to starting study drug or have not recovered from the side effects of such therapy. * Patient must be ≥ 4 weeks since last chemotherapy or treatment with another systemic anticancer agent with the exception of hydroxyurea. Hydroxyurea must be discontinued at least 48 hours prior to the initiation of AUY922. Patients must have recovered (CTC ≤ 1) from acute toxicities of any previous therapy (with the exception of alopecia). * Active anticoagulation with warfarin. * Pregnant or lactating women * Fertile women of childbearing potential (WCBP) not using double-barrier methods of contraception (abstinence, oral contraceptives, intrauterine device or barrier method of contraception in conjunction with spermicidal jelly, or surgically sterile). Male patients whose partners are WCBP not using double-barrier methods of contraception. Impaired cardiac function, including any one of the following: * History (or family history) of long QT syndrome * Mean QTc ≥ 450 msec on baseline ECG * History of clinically manifested ischemic heart disease (including myocardial infarction, stable or unstable angina pectoris, coronary arteriography or cardiac stress testing/imaging with findings consistent with infarction or clinically significant coronary occlusion) ≤ 6 months prior to study start * History of heart failure or left ventricular (LV) dysfunction (LVEF ≤ 45%) by MUGA or ECHO * Clinically significant ECG abnormalities including 1 or more of the following: left bundle branch block (LBBB), right bundle branch block (RBBB) with left anterior hemiblock (LAHB). ST segment elevation or depression \> 1mm, or 2nd (Mobitz II), or 3rd degree AV block. History or presence of atrial fibrillation, atrial flutter or ventricular arrhythmias including ventricular tachycardia or Torsades de Pointes * Other clinically significant heart disease (e.g. congestive heart failure, uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen) * Clinically significant resting bradycardia (\< 50 beats per minute) * Patients who are currently receiving treatment with any medication which has a relative risk of prolonging the QTcF interval or inducing Torsades de Pointes and cannot be switched or discontinued to an alternative drug prior to commencing AUY922. * Obligate use of a cardiac pacemaker
