Safety and Efficacy Study of CYT387 in Primary Myelofibrosis (PMF) or Post-polycythemia Vera (PV) or Post-essential Thrombocythemia (ET)
Trial ID or NCT#
Status
Purpose
This study seeks to (i) determine a safe and tolerated dose of CYT387 (momelotinib) given to patients with PMF, post-PV or post-ET and, (ii) assess the effectiveness of orally-administered CYT387 as a treatment for PMF, post-PV or post-ET.
Official Title
A Phase I/II, Open-Label, Dose-Escalation Study Evaluating the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Orally-Administered CYT387 in Primary Myelofibrosis or Post-Polycythemia Vera or Post-Essential Thrombocythemia Myelofibrosis.
Eligibility Criteria
- * Diagnosis of PMF or post-polycythemia Vera (PV) or post-essential Thrombocythemia (ET) MF as per revised World Health Organization (WHO) criteria.* High-risk or Intermediate-2 risk MF (as defined by the International Prognostic Scoring System \[IPSS\]; Appendix 13.6); or intermediate-I risk MF (IPSS) associated with symptomatic splenomegaly/hepatomegaly and/or unresponsive to available therapy.* Must be at least 18 years of age with life expectancy of ≥ 12 weeks.* Must be able to provide informed consent and be willing to sign an informed consent form.* Must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.* Must have evidence of acceptable organ function within 7 days of initiating study drug as evidenced by the following:
- * Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 2.5 x upper limit of normal (ULN) (or ≤ 5 x ULN if in the investigator's opinion the elevation is due to extramedullary hematopoiesis) * Bilirubin ≤ 2.0 x ULN or direct bilirubin \< 1.0 * Serum creatinine ≤ 2.5 x ULN * Absolute neutrophil count ≥ 500/µL * Platelet count ≥ 50,000/µL* Females of childbearing potential must have a negative pregnancy test within 4 days of initiating study drug.
- * Any chemotherapy (eg, hydroxyurea), immunomodulatory drug therapy (eg, thalidomide), immunosuppressive therapy, corticosteroids \> 10 mg/day prednisone or equivalent, or growth factor treatment (eg, erythropoietin) within 14 days prior to initiation of study drug.* Incomplete recovery from major surgery within four weeks of study entry.* Radiation therapy within four weeks of study entry.* Women of childbearing potential, unless surgically sterile for at least 3 months (ie, hysterectomy), OR postmenopausal for at least 12 months (FSH \> 30 U/mL), OR unless they agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through end of study. Permitted methods for preventing pregnancy must be communicated to study subjects and their understanding confirmed.* Men who partner with a woman of childbearing potential, unless they agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through to the end of study. Permitted methods for preventing pregnancy must be communicated to study subjects and their understanding confirmed.* Females who are pregnant or are currently breastfeeding.* Known positive status for HIV.* Clinically active hepatitis B or C.* Diagnosis of another malignancy unless free of disease for at least three years following therapy with curative intent. Patients with early-stage basal cell or squamous cell skin cancer, cervical intraepithelial neoplasia, cervical carcinoma in situ or superficial bladder cancer may be eligible to participate at the Investigator's discretion.* Any acute active infection.* Cardiac dysrhythmias requiring treatment, or prolongation of the QTc (Fridericia) interval to \> 450 msec for males or \> 470 msec for females at prestudy screening, unless attributable to pre-existing bundle branch block.* Presence of ≥ Grade 2 peripheral neuropathy.* Uncontrolled congestive heart failure (New York Heart Association Classification 3 or 4), uncontrolled or unstable angina, myocardial infarction, cerebrovascular accident, or pulmonary embolism within 3 months prior to initiation of study drug.* Uncontrolled inter current illness or any concurrent condition that, in the Investigator's opinion, would jeopardize the safety of the patient or compliance with the protocol.
