NCT00334737
Infants born prematurely do not increase production of the primary red cell growth factor, erythropoietin (Epo), and often develop an anemia called the "anemia of prematurity." The anemia of prematurity is the most common anemia seen in neonates, and is due to a failure of Epo production. Human recombinant Epo (rHuEpo), given three to five times a week, is successful in treating the anemia of prematurity. A slightly modified, long-acting version of rHuEpo, called darbepoetin alfa (darbepoetin), is now available and has proven effective in increasing hematocrit (red blood cell levels) in adults. In addition to its red cell stimulating properties, recent evidence has shown that rHuEpo is protective in the developing or injured brain. We have designed a randomized, masked, placebo-controlled study to determine the safety and short and long term efficacy of darbepoetin. At this time, darbepoetin has been studied primarily in adults and pediatric patients, but there is evidence from pilot studies that darbepoetin would be useful in the neonatal setting as well. It also may well improve neurodevelopmental outcomes in preterm neonates. We hypothesize that: 1. The administration of darbepoetin to preterm infants 500 to 1,250 grams birth weight will result in increased reticulocyte counts and decreased transfusions compared to placebo; and 2. The administration of darbepoetin will be associated with an increased mental developmental index at 18-22 months compared to placebo.

The myeloproliferative neoplasms (MPN), most notably polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are a diverse but inter-related suite of clonal disorders of pluripotent hematopoietic stem cells (Tefferi et al., 2008). The MPN share a range of biological, pathological, and clinical features including the relative overproduction of one or more cells of myeloid origin, growth factor independent colony formation in vitro, marrow hypercellularity, extramedullary hematopoiesis, spleno- and hepatomegaly, and thrombotic and/or hemorrhagic diatheses (Tefferi et al., 2005). This is a multi-centre, open-label, non-randomized, dose-escalation study, to be conducted in two phases: a dose-escalation phase (Part 1), to determine the safety and tolerability of momelotinib (CYT387), and to identify a therapeutic dose for the expanded cohort; and a dose-confirmation phase (Part 2), which will be a cohort expansion at or below the MTD of momelotinib. In the Part I dose-escalation phase of the study, subjects will be assigned to dose levels in successive cohorts starting with a dose in the first cohort of 200 mg BID (twice daily with doses taken approximately 12 hours apart). Doses will be escalated by 50 mg BID per cohort until dose-limiting toxicities are observed. The dose level at which ≥2 of 6 subjects develop a first cycle dose-limiting toxicity (DLT) is defined as the DLT level. The maximum tolerated dose (MTD) is defined as the dose level below the DLT level. New dose levels may begin accrual only if all subjects at the current dose level have been observed for a minimum of 28 days from the first day of treatment. The dose level chosen for study in the dose confirmation phase of the study will be the MTD or a lower dose shown to have significant clinical activity (efficacy) as determined by the safety review committee. Subjects will be evaluated weekly for the first cycle, every 2 weeks during cycle 2, then monthly for 4 cycles for a total of 6 cycles. In the dose-confirmation phase of the study, approximately fifty (50) subjects will be treated at the MTD or at a lower dose shown to have significant clinical activity (efficacy) as chosen by the Safety Review Committee. In the dose confirmation phase of the study subjects will be evaluated every 2 weeks during the first treatment cycle, and then monthly for 5 cycles for a total of 6 cycles.
