Myeloproliferative Neoplasms Clinical Trial
The First-in-human Phase I Trial of PU-H71 in Patients With Advanced Malignancies
NOTE: This study is now recruiting only patients with Myeloproliferative Neoplasms (MPN). Dose escalation has been completed.
The purpose of this study is to test a new drug, called PU-H71 for the first time in humans, to find out what effects, good or bad, this new drug has on the patient and the cancer at different dose levels. PU-H71 blocks a protein called Heat Shock Protein-90 (Hsp90). Hsp90 is found in both normal and cancer cells, but may be more important in cancer cells. Attacking Hsp90 can stop the function of certain proteins that are needed for cancer cells to survive. The diseases that are part of this study may be especially sensitive to attacking Hsp90, and the investigators have seen signs of disease control in patients with MPN. This study is currently enrolling a cohort expansion for patients with myeloproliferative neoplasms (MPN).
The safety-expansion phase will be open to accrual only for patients with MPN.
≥ 18 years of age
For patients with solid malignancies and lymphoma, radiographically detectable (Either FDG-PET, CT scan/ MRI or Bone Scan) or measurable disease will be required. Measurable disease is defined as at least one measurable lesion ≥ 10 mm on CT scan (15 mm for nodal lesions).
Prior therapy for advanced malignancy with no current curative option
Neutrophil count ≥ 1,000/μL, platelet count ≥ 50,000/μL, and hemoglobin ≥ 8 g/dL (Platelet count must be assessed at least 7 days after a prior transfusion, if any)
Serum bilirubin ≤ 1.5 mg/dL;
AST and ALT≤ 1.5 × ULN
Serum creatinine ≤ 1.5 mg/dL or creatinine clearance of ≥ 50 mL/min based on a 24-hour urine collection
Patients receiving hydroxyurea may continue receiving it for up to 14 days after the start of protocol treatment if WBC >30 x10^9/L.
Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
Patients with HIV/AIDS are allowed on study if they have an undetectable viral load, CD4 > 300 and on stable Highly Active Antiretroviral Therapy (HAART) regimen for 1 month.
Patients who have been treated for at least two weeks with stable doses of corticosteroids to address conditions unrelated to their malignancy will be allowed to continue this treatment during enrollment on the current trial.
Patients currently being treated with a gonadotropin-releasing hormone agonist (GnRH agonist), bicalutamide or with bisphosphonates may continue treatment while on clinical trial PU-H71 as long as the treatment has been initiated before the study start. GnRH agonist must have been well tolerated for at least three months.
Optional participation in the microdose imaging trial, IRB#10-139.
Signed written informed consent and HIPAA consent.
PATIENTS WITH MPN must be:
On ruxolitinib for at least three months and on a stable dose for at least 1 month prior to enrollment and taking at least 5 mg twice daily of ruxolitinib
Tolerating ruxolitinib but with persistent manifestations of disease (i.e. persistent splenomegaly, abnormal blood counts, persistent constitutional symptoms residual fibrosis in bone marrow (2+ or greater), or measurable allele burden as evidenced of clonal JAK2 or MPL mutation).
Ruxilitinib treatment requirements will be waived for patients who have failed this treatment in the past or for whom this treatment is otherwise contraindicated
Ejection fraction < 50%, as determined by echocardiogram or MUGA scan
Symptomatic brain or CNS metastases. Previously treated and stable CNS disease is allowed.
Any of the following for the treatment of cancer within 2 weeks of first study treatment: chemotherapy, immunotherapy, experimental therapy or biologic therapy.
Any major surgical procedure or radiation within 4 weeks of first study treatment
Active liver disease, including viral or other hepatitis, or cirrhosis
Pregnancy or lactation
Active hepatitis or other active infections
Any other significant medical condition not under control, including any acute coronary syndrome within the past 6 months.
Patients with a permanent pacemaker
Patients with a QTcF or QTcB > 480 ms in the baseline EKG
Systemic corticosteroids (e.g. prednisone ≥ 12.5 mg/day or dexamethasone ≥ 2 mg/day) for the purpose of palliating tumor-related symptoms will not be allowed within 1 week of starting treatment on trial.
