BACKGROUND Ruxolitinib, a selective inhibitor of Janus kinase (JAK) 1 and 2, has clinically significant activity in myelofibrosis. METHODS In this double-blind trial, we randomly assigned patients with intermediate-2 or high-risk myelofibrosis to twice-daily oral ruxolitinib (155 patients) or placebo (154 patients). The primary end point was the(More)
Busulfan pharmacokinetics, specifically area under the concentration curve (AUC), have been correlated with the occurrence of veno-occlusive disease (VOD) following BMT. To evaluate the risk of VOD, we studied 66 patients who received pharmacotherapeutically monitored busulfan regimens in combination with CY, etoposide (VP16) and/or Ara-C in preparation for(More)
We have studied the effect of recombinant human hematopoietic growth factors (interleukin-3 [rhIL-3], granulocyte-macrophage colony-stimulating factor [rhGM-CSF], and granulocyte CSF [rhG-CSF]) on the clonal growth of human colon adenocarcinoma cell lines HTB-38, CCL 187, and WiDr (CCL 218). The factors stimulated clonal growth of HTB-38 and CCL 187 in a(More)
In the phase III COMFORT-I study, the Janus kinase 1 (JAK1)/JAK2 inhibitor ruxolitinib provided significant improvements in splenomegaly, key symptoms, and quality-of-life measures and was associated with an overall survival benefit relative to placebo in patients with intermediate-2 or high-risk myelofibrosis. This planned analysis assessed the long-term(More)
Thirty patients with blastic transformation of chronic granulocytic leukemia were treated with a combination of daunorubicin, 5-azacytidine, 6-thioguanine, and cytarabine. Hematopoietic toxic effects were substantial and eight of 23 patients developed hepatic dysfunction (bilirubin greater than 5.5 mg/dl). Although the regimen resulted in marked decrease in(More)
PURPOSE To assess the effects of ruxolitinib on symptom burden and quality of life (QoL) and to evaluate the ability of the modified Myelofibrosis Symptom Assessment Form (MFSAF) v2.0 to measure meaningful changes in myelofibrosis-related symptoms in patients with myelofibrosis. PATIENTS AND METHODS COMFORT-I (Controlled Myelofibrosis Study With Oral JAK(More)
Recombinant human interleukin-6 (IL-6) has previously been shown to increase platelet counts in mice and primates. To elucidate the mechanisms underlying this phenomenon, serial analyses were performed on megakaryocytes obtained from rhesus monkeys treated for 8 days with 30 micrograms/kg/d of recombinant human IL-6. Platelet counts increased to a maximum(More)
Initial studies of FK506 combined with methotrexate (MTX) in patients receiving unrelated donor BMT have demonstrated a possible-decrease in the incidence of severe GVHD but high rates of severe stomatitis and nephrotoxicity. With this background, we undertook a pilot study evaluating FK506 in combination with a lower than usual dose of MTX in an attempt to(More)
Treatment of chronic myeloid leukemia (CML) has seen dramatic progress in recent years with the development of tyrosine kinase inhibitors (TKIs). To take maximum advantage of therapy with TKIs, compliance and good understanding of monitoring response to therapy are essential. We established a team that included a hematologist, a physician assistant (PA),(More)
A 43-year-old male with a phenotypically homogeneous, expanded subset of T cells presented in 1981 with anemia and neutropenia. The surface antigen phenotype of 99% of the peripheral blood lymphocytes was T3+, T8+, T4-, and they were morphologically large granular lymphocytes (LGL). The same cells comprised 37% of the marrow nucleated cells. Eight months(More)
