Filter by:Phase 1, single-center, open-label, sequential cohort dose escalation study. This is a 3 + 3 design study involving at least 3 subjects in ascending dose cohorts, with subjects participating up to 10 weeks. The overall study objectives are to evaluate the safety and tolerability of TXA127 in thrombocytopenic subjects with low or intermediate-1 risk MDS. Evaluation of the platelet response and the erythroid and granulocytic responses to TXA127 will provide preliminary efficacy data.
Transfusional dependence has been associated closely and independently with low survival in patients with myelodysplastic syndrome (MDS), especially in patients at low risk according to IPSS. Treatment of patients with hydralazine + valproic acid as an alternative to treatment with 5-azacytidine has lower cost and possibly as effective with fewer side effects. The objective of this phase II study is to determine the effectiveness of combination therapy with hydralazine + Ac. Valproic compared with best supportive care. The investigators will select 42 patients per group, and after 14 weeks of treatment the investigators will study in both groups the hematological response (transfusion-dependent, hemoglobin, cytogenetics and morphology) and treatment safety (adverse reactions and vital signs) to 1 year after starting treatment. The concentration of hemoglobin, the number of transfusions, platelets, neutrophils and other continuous variables in both groups will be compared by Student t or Mann-Whitney, as appropriate. For comparison of cytogenetic and morphological response and other categorical variables between groups Chi square will be used. And within each group the investigators will compare each of these variables before and after treatment by t-test for paired data or Wilcoxon test.
In myelodysplastic syndromes (MDS) the knowledge about chromosomal aberrations is important for diagnosis, pathogenesis, prognosis and treatment. Usually, chromosomal anomalies in MDS patients are detected in bone marrow cells by chromosome banding analyses of metaphases. Alternatively or additionally they can be diagnosed by Fluorescence-in-Situ-Hybridization (FISH). The investigators here present a novel method for cytogenetic monitoring of MDS patients from peripheral blood which is representative for the clone size in bone marrow cells. The purpose of this prospective multicenter non-interventional diagnostic study is to detect and to follow chromosomal aberrations from peripheral blood closely, to assess karyotype evolution, to detect rare abnormalities and to correlate the molecular-cytogenetic results with peripheral blood counts, bone marrow morphology and treatment modalities and responses.
This is a research study involving the treatment of patients with hematological cancers with allogeneic (cells from a donor) hematopoietic stem cell transplant (HSCT). HSCT is often referred to as bone marrow transplant. Patients who are not expected to have long term survival after conventional therapy will undergo HSCT as a curative therapy after receiving front line therapy for their disease. This project is based on an HSCT approach that has been used at TJU since 2006 with the goal of optimizing this type of treatment further. In this new study, the investigators will substitute the chemotherapy agent, Melphalan (Mel), for cyclophosphamide (CY). Cyclophosphamide was used in the original trial. The research question is whether side effects are less using Mel and if donor T cells can be made tolerant to the recipient with the use of Mel. The proposed study is also more specific in terms of performance status and organ function entry criterion. The investigators observed in the original trial that patients with poor performance upon admission for transplant did not have as good outcomes. Because many older patients are treated according to this type of transplant, the chemotherapy and radiation used are less intensive than other types of transplant. The name for this in the transplant field is a reduced intensity hematopoietic stem cell transplant. The abbreviations most used in this document are RIC for reduced intensity conditioning, HSCT which refers to the transplant itself, and MEL which refers to the drug, Melphalan.
The primary hypothesis of this research study is that patients in remission undergoing myeloablative haploidentical hematopoietic stem cell transplantation (HSCT) on the Thomas Jefferson University (TJU) 2 Step treatment regimen will have a disease-free survival (DFS) rate at 1 year that is the same or better than the historical DFS of patients with similar diagnoses and ages undergoing matched sibling HSCT. Based on a review of the literature a DFS rate of 50% or better at 1 year would meet the criterion for an effective alternative therapy. A DFS rate of 75% or better would imply superior efficacy of the TJU 2 Step approach over T-replete matched sibling HSCT.
This randomized phase II trial is studying how alvocidib, cytarabine, and mitoxantrone hydrochloride work compared to cytarabine and daunorubicin hydrochloride in treating patients with newly diagnosed acute myeloid leukemia. Alvocidib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine, mitoxantrone hydrochloride, and daunorubicin hydrochloride work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving alvocidib, cytarabine, and mitoxantrone hydrochloride is more effective than giving cytarabine and daunorubicin hydrochloride in treating patients with acute myeloid leukemia.
The purpose of this study is to collect clinical and laboratory data for patients affected by intermediate 1 and low risk Myelodysplastic Syndrome (MDS) associated by deletion 5q who were prescribed Revlimid from 31October 2008 to present. Revlimid is available in Italy for these patients since October 2008 based on a local disposition of the Italian Drug Agency (AIFA) issued according to a National law named 648/96.
In order to improve the overall survival benefit observed with AZA in higher risk MDS, its combination with other active drugs in MDS must be tested. Among drugs that have demonstrated to be active as a single agent in MDS and have preclinical potential additive or synergistic activity with AZA are Histone deacetylase (HDAC) inhibitors including Valproic acid, Lenalidomide and idarubicin. Phase I studies have already been conducted or are being conducted combining those agents to demethylating agents, showing a low toxicity profile and significant responses in high risk MDS. In this phase II randomized trial, we want to identify the most promising combination of Azacitidine and another drug (among 3 drugs: Valproic acid, Lenalidomide and Idarubicin) in higher risk MDS, by comparison to Azacitidine alone. Of note, based on efficacy and toxicity, one or several combinations may be stopped, and others, previously tested in phase I trials, included after protocol amendment.
This research is being done to learn more about nonmyeloablative bone marrow transplantation (BMT), also known as a "mini" transplant for patients with blood cancers, using bone marrow from a relative.
Long-term follow-up studies have demonstrated significant late toxicities of total body irradiation (TBI), which are most marked in children radiated at a young age. Growth failure, decline in cognitive function, and endocrine abnormalities have all been described. Good outcomes can be achieved with alkylating agents only as a preparative regimen. This plan will use a combination of busulfan and cyclophosphamide (Bu/Cy) with or without antithymocyte globulin (ATG) to reduce the late toxicities of therapy that includes TBI.
