A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS) Clinical research trials and A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS) medical trials occur in many of places across the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectiveness of new does drugs. The role of the studies / undertakings is to figure out certain human healthcare questions. Clinical trials are a popular means for doctors, government agencies, and private sector corporations to locate treatments for all forms of circumstances, including A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS). A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS) Clinical Trials and other clinical trials permit volunteers to get medical treatment options before they are available to the masses. Most times the human subjects acquire treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS) clinical trial. Participants oftentimes recieve the finest healthcare available for their A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS) condition. Dangers are a reality, nonetheless, and might include extra or frequent physician calls, health hazards (potentially life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials subjects.

A Randomized Trial of Recombinant Humanized Anti-IL-2 Receptor Antibody (Daclizumab) Versus Antithymocyte Globulin (ATG) to Treat the Cytopenia of Myelodysplastic Syndrome (MDS)
For Condition: Myelodysplastic Syndromes
Status: Recruiting
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: This study will evaluate a new immunosupressive therapy, Daclizumab, and compare it with antithymocyte globulin (ATG) to treat cytopenia, that is, the deficiency of cellular elements of the blood, in myelodysplastic syndrome (MDS). Daclizumab is an anti-interleukin-2 receptor (IL-2) antibody. MDS, also known as myelodysplasia, is a disorder that can cause anemia, spontaneous bleeding, and greater risk of infections. Although the bone marrow can still produce some blood cells, very few reach the bloodstream. The cause of MDS is not known, although its behavior is. Many patients need transfusions of red blood cells. They may also develop leukemia, which is often quite resistant to treatment with chemotherapy. However, the progression of the disorder to leukemia is usually slow, taking many years. Patients 18 years of age and older who have MDS may be eligible for this study. Participants will undergo the following tests and procedures: -Medical history and physical examination. -Collection of blood for tests including blood counts, liver and kidney function, and antibodies against common viruses. -Chest x-ray. -Electrocardiogram. -Bone marrow sample to confirm the diagnosis. Participants will randomly receive either ATG or Daclizumab. If they are in the group to receive ATG, they will be admitted as inpatients to undergo the first 10 to 14 days of treatment. If they do not already have a catheter in one of the large veins of the neck, chest, or arm, one will be placed. ATG will be given through the catheter. Blood counts and other blood analysis will be monitored daily while the patients are treated. After about 10 days, they will be released, to be under the care of their referring physicians. Those participants who are in the group to receive Daclizumab will receive a total of five doses, one every 2 weeks, over 8 weeks, given through a vein as a 15-minute infusion. The first, third, and fifth dose will be given at the outpatient clinic. The second and fourth doses can be given either at the clinic or by the patients' primary hematologists. All patients will be followed as outpatients at 3-month intervals for the first year, and then every 6 months for the next 3 years. Afterward, follow-up will be yearly. A small sample of blood will be drawn at the visits. Also, bone marrow examinations will be requested at the 6-month intervals for the first 3 years of treatment. If the treatment that patients are assigned to does not work, after 6 months, they will be eligible to receive the other treatment-provided that they have complied with the required blood tests and visits to the clinic required to assess the patients' safety.
Details: Many bone marrow failure syndromes in humans are now recognized to result from immunological mechanisms. These diseases include aplastic anemia, pure red cell aplasia, and some types of myelodysplasia. Patients with these conditions, who may suffer variable degrees of anemia, leukocytopenia, and thrombocytopenia, alone or in combination, have been shown to respond to a wide variety of immunosuppressive agents, ranging from corticosteroids to cyclosporine (CSA) and antithymocyte globulin (ATG), however, nonresponse and relapse continues to be a problem. Why some patients do not respond initially or others respond and then relapse is unclear. Autoreactive T cells may be resistant to the effect of ATG/CsA (nonresponders), while in others residual autoreactive T cells expand post-treatment leading to hematopoietic stem cell destruction and recurrent pancytopenia (relapse). Therefore, novel, less toxic immunosuppressive regimens that increase response rates and hematologic recovery and decrease relapse rates are needed. One such novel therapy, Daclizumab, a humanized anti-interleukin-2 receptor (lL-2R) monoclonal antibody (mAb), acts against activated lymphocytes, thus sharing an important mechanism of action with ATG. The mAb is much less toxic than ATG and may be administered to outpatients at relatively infrequent intervals (every 2 weeks). Treatments with ATG alone and CsA alone have demonstrated varying degrees of success in alleviating the cytopenia of MDS. Our experience suggests that ATG rather than CSA is the more effective agent inducing hematological responses in susceptible MDS patients and that certain variables including the patient's age, whether or not they were HLA DR15, and days of red cell transfusion dependence prior to treatment were predictive of response. We therefore propose this randomized phase II study to evaluate and compare a new immunosuppressive therapy, Daclizumab, with antithymocyte globulin (ATG) to treat the cytopenia of MDS in a population of subjects with intermediate or high predicted probability of response.
