Filter by:The design of a phase I, open label, dose finding study was chosen in order to establish a safe and tolerated dose of single agent ABL001 in Chronic myeloid leukemia (CML) and Philadelphia chromosome positive Acute lymphoblastic leukemia (Ph+ ALL) patients who are relapsed or refractory to or are intolerant of Tyrosine kinase inhibitors (TKIs), and of ABL001+Nilotinib, ABL001+Imatinib and ABL001+Dasatinib in Ph positive CML patients who are relapsed or refractory to TKIs.
Prospective nonrandomized phase I study The purpose of this study is to determine safety and efficacy of zileuton when added to dasatinib in patients with chronic myelogenous leukemia (CML).
This is a treatment guideline for an unrelated umbilical cord blood transplant (UCBT) using a myeloablative preparative regimen for the treatment of hematological diseases, including, but not limited to acute leukemias. The myeloablative preparative regimen will consist of cyclophosphamide (CY), fludarabine (FLU) and fractionated total body irradiation (TBI).
This randomized clinical trial studies standard GVHD prophylaxis with tacrolimus and methotrexate compared to tacrolimus, mycophenolate mofetil and a reduced-dose methotrexate in patients with hematologic malignancies undergoing allogeneic hematopoietic cell transplant. Both mycophenolate mofetil and reduced-dose methotrexate, in combination with a calcineurin inhibitor, have been shown to be safe and effective in GVHD prevention with less toxicity than standard dose methotrexate. It is not yet known, however, whether this combination of mycophenolate mofetil and reduced-dose methotrexate with tacrolimus is more effective than tacrolimus and standard dose methotrexate in preventing GVHD.
CML is a myeloproliferative disorder defined by the presence of the Philadelphia chromosome, which arises from the reciprocal translocation of genes on chromosomes 9 and 22.It is rare in childhood and accounts for 2-3% of all leukemias in childhood. BCR-ABL gene on Philadelphia chromosome results in a 210kd fused BCR-ABL protein with constitutive tyrosine kinase activity, and subsequent activation of cytoplasmic and nuclear signal transduction pathways including STAT, RAS, JUN, MYC, and phosphatidylinositol-3 kinase. The ultimate result of such activation is the myeloid proliferation and differentiation and suppressed apoptosis. Children present with a higher WBC count, otherwise presentation is nearly identical to adults. Current treatment include tyrosine kinase inhibitors (TKI) and allogeneic stem cell transplant (SCT).Imatinibmesylate inhibits the tyrosine kinase (TK) activity of BCR-ABL1 and several related TKs, including c-kit and the platelet-derived growth factor receptor (PDGFR). Development of tyrosine kinase inhibitor (TKI) therapy has revolutionizedtreatment of CML. Imatinib or second generation TKIs (dasatinib or nilotinib) have become standard front-line therapy forchildren and adults with CML and are also important componentsof therapy for Ph+ acute lymphoblastic leukemia (ALL). TKIs are administered orally and cause a number of side effects including fatigue, hypertension, rash, impaired wound healing, myelosuppression, and diarrhea . The overall toxicity of TKIs, while less life-threatening than conventional cytotoxic chemotherapy, nevertheless is common, and may require dose reduction.Recently, proposed endocrine-related side effects of these agents include alterations in thyroid function, bone metabolism, linear growth, gonadal function, fetal development, glucose metabolism and adrenal function. Growth impairment is one of the major adverse effect of long-term imatinib treatment in children with CML. Multiple case reports have demonstrated growth retardation in children onimatinib.Imatinibmesylate inhibits the TK activity of BCR-ABL1 and several related TKs, including c-kit and theplatelet-derived growth factor receptor (PDGFR). It isthe inhibition of TK activity at the non-BCR-ABL sites that couldbe the likely cause for the adverse effect on growth. Severalstudies in adults have suggested that inhibition of c-kit,c-fms, and PDGF receptors results in modulation of bone metabolism. Other reports are focusing on disturbance of the growth hormone (GH) axis as a mechanism for growth impairment. Receptor and non receptor TK is expressed at multiple levels in GH-IGF-1 axis including GHRH-R, GH-R and IGF-1R. Inhibition of TKs with TKI, at any one of these level, might result in growth impairment. Various studies are available to show that Imainib therapy may cause short stature in children on prolonged treatment but exact mechanism by which this occurs is still not clear. Further, no treatment modality has been tried so far, for short stature in these children. So, the purpose of this study is to study GH-IGF1 axis in these children and to administer GH therapy to GH deficienct children in remission.
To provide the IRB approved mechanism for the prospective collection, analysis and reporting of data on patients who are undergoing either an autologous or allogeneic hematopoietic stem cell transplant for a disease in which a research question is not being addressed and for which peer reviewed, published data have demonstrated efficacy for this treatment approach.
The main purpose of the study was to investigate whether nilotinib treatment can be safely suspended with no recurrence of CML in selected patients who responded optimally on this treatment
It is an open-label, randomized, double blind, placebo-controlled parallel-group, multi-center study to evaluate the efficacy and safety of Compound realgar formula Realgar-Indigo naturalis Tablet combined with Imatinib will be compared with imatinib alone in adult patients with diagnosed Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia in the chronic phase (CML-CP).
This is a Phase II, open-label, two strata, multicenter, prospective study of plerixafor-mobilized HLA-identical sibling allografts in recipients with hematological malignancies. This study will establish the safety and efficacy of subcutaneous plerixafor for this purpose.
This randomized phase II trial studies how well donor umbilical cord blood transplant with or without ex-vivo expanded cord blood progenitor cells works in treating patients with acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, or myelodysplastic syndromes. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy stem cells and ex-vivo expanded cord blood progenitor cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether giving donor umbilical cord blood transplant plus ex-vivo expanded cord blood progenitor cells is more effective than giving a donor umbilical cord blood transplant alone.
