HSP90 Inhibitor, AUY922, in Patients With Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (Post-PV MF), Post-Essential Thrombocythemia Myelofibrosis (Post-ET MF), and Refractory PV/ET

Stopped early · Phase 2

Conditions studied: Myeloproliferative Neoplasms

In brief

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.

• 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.

You may not qualify if…

• 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.

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

• 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
