Active clinical trials for "Thalassemia"

This study will assess the safety and efficacy of deferasirox in patients with cardiac MRI T2* < 20 msec.

The purpose of this study is to determine if treatment with reduced-dose busulfex, fludarabine and alemtuzumab (CAMPATH) followed by sten cell infusion will allow for donor stem cells to grow in patients with hemoglobinopathies bone marrow and restore circulating blood counts. In addition the incidence and severity of side effects and of graft vs. host disease (GVHD) will be monitored.

The purpose of this study is to determine the effects of the oral iron chelator Deferasirox on liver iron content after one year of treatment in patients with iron overload from repeated blood transfusions. Beta-thalassemia patients unable to be treated with deferoxamine or patients with rare chronic anemias such as Myelodysplastic Syndrome, Fanconi's Syndrome, Blackfan-Diamond Syndrome, and Pure Red Blood Cell Anemia are eligible for this study. Liver iron content will be measured by liver biopsy at the beginning of the study and after one year of treatment. However, those patients living in the San Francisco/Oakland area may have a SQUID in place of the liver biopsy if the biopsy is not medically possible for them. The SQUID is a non-invasive magnetic means to measure liver iron content.

OBJECTIVES: I. Determine whether arginine butyrate with or without epoetin alfa can stimulate gamma-globin chain production to a degree that decreases anemia and results in hematologic improvement in patients with thalassemia intermedia. II. Determine whether a proportional increase in gamma-globin synthesis and mRNA and an improvement in nonalfa and alfaglobin chain imbalance by at least 10% over baseline correlate with improved hematologic response in these patients when treated with this regimen. III. Determine whether a decrease in hemolysis, as assayed by a decrease in LDH, compared to baseline levels correlates with improved hematologic response in these patients when treated with this regimen. IV. Determine whether any particular genotypes are more responsive than others to this therapy in these patients. V. Determine whether baseline epoetin alfa levels, gender, and/or baseline reticulocyte counts (or percent circulating nucleated erythroblasts) correlate with improved hematologic response in these patients when treated with this regimen.

This 12-month study will evaluate the safety and effectiveness of hydroxyurea in treating beta-thalassemia, a type of anemia caused by defective hemoglobin (the oxygen-carrying pigment in blood). Hemoglobin is composed of two protein chains-alpha globin chains and beta globin chains; patients with beta-thalassemia do not make beta globin. Patients often require frequent red blood cell transfusions. This leads to iron overload, which, in turn, requires iron chelation therapy (removal of iron from the blood). Some drugs, including hydroxyurea, can stimulate production of a third type of protein chain called gamma chains. In the womb, the fetus makes this type of protein instead of beta globin. It is not until after birth, when the fetus no longer produces gamma globin that the beta globin deficiency becomes apparent. Gamma chain synthesis improves hemoglobin and red blood cell production, correcting the anemia. This study will determine if and at what dose hydroxyurea treatment reduces patients' need for red blood cell transfusions and whether certain factors might predict which patients are likely benefit from this treatment. Patients 15 years and older with moderately severe beta-thalassemia may be eligible for this study. Participants will take hydroxyurea daily at a dose calculated according to the patient's body size. Blood will be drawn weekly to measure blood cell and platelet counts. The drug dosage may be increased after 12 weeks of treatment and again after 24 weeks if the white cell and platelet counts remain stable. Patients who respond dramatically to treatment may continue to receive hydroxyurea for up to 3 years.

A pilot study to explore safety and efficacy of NBMI treatment in patients with Beta Thalassemia Major requiring iron chelation Investigational product: NBMI (N1,N3-bis(2-mercaptoethyl) isophthalamide), INN: Emeramide Indication: Beta Thalassemia Major

An open label, safety and pharmacokinetic study of oral hydroxyurea solution administered to children from 6 months to 17.99 years (i.e. to the day before 18th birthday), with a 12 to 15 month treatment period for each participant. The study treatment duration will be for 6 months at the maximum tolerated dose [MTD], which is usually reached by 6 months after initiation of treatment. For patients in whom time to MTD is longer than 6 months or not achieved at all, the maximum duration of study treatment will be 15 months.

This study is a multicenter, open-label, two-period crossover design that evaluates the safety, tolerability, pharmacokinetics and preliminary evidence of iron chelating activity of DST-0509 as compared to Jadenu and Exjade in transfusion-dependent thalassemia patients with transfusional iron overload, requiring iron chelation therapy and demonstrating an inadequate response to Jadenu or Exjade for greater than 3 months duration. Up to 36 patients will be evaluated (18 in each treatment arm), however, the balanced randomization may enroll fewer patients based on recruitment status.

This is a single-site, randomized, placebo-controlled, double blind phase 2b clinical trial. Patients with Thalassemia will participate in this study and will be treated with Denosumab or placebo. The effect of Denosumab on lumbar spine BMD in patients with Thalassemia Major and Osteoporosis will be evaluated as compared with control (placebo) at 12 months.

This is a single-arm, multi-site, single-dose, Phase 3 study in 23 participants less than or equal to (<=) 50 years of age with transfusion-dependent β-thalassemia (TDT), also known as β-thalassemia major, who do not have a β0 mutation at both alleles of the hemoglobin β (HBB) gene. The study will evaluate the efficacy and safety of autologous hematopoietic stem cell transplantation (HSCT) using LentiGlobin BB305 Drug Product.
