About this study
Official title: A Pilot Study of Alemtuzumab (Campath[R]) in Patients With Myelodysplastic Syndrome (MDS)
This study will evaluate the safety and effectiveness of a genetically engineered antibody, alemtuzumab (Campath[R]) on patients with myelodysplastic syndrome. MDS is made up of malignant stem cell disorders that can mean low levels of red blood cells-that is, anemia-and low counts of white blood cells and platelets. Patients with MDS are at risk for infection, spontaneous bleeding, and possible progression to leukemia, a cancer of bone marrow. Although bone marrow can produce some blood cells, patients with MDS experience a decrease in production of blood cells. Alemtuzumab recognizes specific types of white cells called lymphocytes and destroys them. This study will examine not only the usefulness of the medication but also the side effects in patients with MDS.
Patients ages 18 to 72 who have MDS that requires transfusions and who do not have HIV or a life expectancy of less than 6 months may be eligible for this study. Screening tests include a complete physical examination and medical history. There will be a collection of about 8 tablespoons of blood for analysis of blood counts as well as liver, kidney, and thyroid function; a pregnancy test; an electrocardiogram (EKG) to measure electrical activity of the heartbeat; an echocardiogram (ECHO), which uses sound waves to evaluate heart function; wearing of a Holter monitor for 24 hours while the electrical activity of the heart is recorded; and a bone marrow biopsy. Patients should not receive any vaccines when taking alemtuzumab or for at least 12 months after the last dose. In addition, patients should not take the herbal supplements Echinacea purpurea or Usnea 2 weeks before beginning the study and during it.

For the study, all patients will receive a test dose of 1 mg of alemtuzumab infused into a vein during the course of 1 hour. If the dose is tolerated, the medication will be given at 10 mg doses into the vein for 10 days, as an infusion of 2 hours. Blood samples of 2 tablespoons will be taken daily, and vital signs will be measured daily. The ECHO and 24-hour Holter monitoring will be repeated after patients receive the last dose of the medication. Because suppression of the immune system results from a decrease in white cells that fight infections, patients will take medications to protect them against infections and to treat them if infections occur. If needed, patients will receive blood transfusions for their MDS. Side effects of alemtuzumab involve a temporarily significant lowering of the number of red blood cells, white cells, and platelets. Side effects of the infusion can be rigidity, or stiffness, and fever, as well as risks of infections resulting from the decrease of white blood cells. Blood counts and reactions to all procedures will be carefully monitored throughout the study. After patients receive the last dose of alemtuzumab, they will have follow-up by their referring doctor or at NIH. They must be able to return to NIH after 1 month, 3 months, 6 months, and annually for 5 years after the study. At follow-up visits, there will be blood tests to reevaluate blood counts and test for the presence of viruses. Blood tests will be done weekly for the first 3 months after patients have completed taking alemtuzumab, every other week until 6 months, and then annually for 5 years. There will also be a repeat ECHO at the 3-month visit, and a repeat bone marrow biopsy at the 5-month and 12-month follow-up visits, and as needed after that.
This study may or may not have a direct benefit for participants. For some, the antibody may improve blood counts and decrease the need for transfusions. Knowledge gained in the study may help people in the future.
Read the detailed description
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, leukopenia, 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 horse antithymocyte globulin (h-ATG). However, non-response 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 h-ATG/CsA (non-responders), 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, alemtuzumab (Campath[R]) is a humanized IgG1 monoclonal antibody directed against the CD52 protein, which is highly expressed on all lymphoid cells and monocytes. Alemtuzumab (Campath[R]), produces profound and persistent lymphopenia, affecting predominantly the CD4+ T cell subset. This property has made it attractive in the treatment of a wide range of diseases including rheumatoid arthritis, multiple sclerosis, ocular inflammatory disease, lymphoid malignancies, organ allograft rejection, and in conditioning regimens in stem cell transplantation to prevent graft failure and graft-versus-host disease.
We therefore propose a non-randomized, off label, pilot, Phase I/II study of alemtuzumab (Campath) in MDS patients who are likely to respond to immunosuppression.
Primary endpoints will be changes in peripheral blood counts (platelets, absolute neutrophil count, reticulocyte count, hemoglobin). Secondary endpoints (in transfusion-dependent patients) include improvement in the transfusion requirements (measured as decrease in the number of transfusion administered on as needed basis), duration of response, late effects of treatment, relapse and survival.

What is being measured
The primary outcome is the main question the study is designed to answer.
Response to Treatment - Hematologic Improvement or Complete Response
Response to treatment at 3 months after the first dose of alemtuzumab. The parameters for hematologic improvement (HI) and complete response (CR) were defined according to the International Working Group (IWG) criteria. The IWG criteria for HI define specific responses of cytopenias in the 3 hematopoietic lineages: erythroid (HI-E), platelet (HI-P), and neutrophil (HI-N).7 The HIs are measured in patients with pretreatment abnormal values: hemoglobin level less than 110 g/L (11 g/dL) or RBC-transfusion dependence, platelet count less than 100 × 109/L or platelet-transfusion dependence, absolute neutrophil count (ANC) less than 1.0 × 109/L.
The parameters for CR include less than 5% marrow blasts without evidence of dysplasia and normalization of peripheral blood counts, including a hemoglobin level of 110 g/L (11 g/dL) or more (in patients not receiving erythropoietin or transfusions), a neutrophil count of 1.5 × 109/L or more, and a platelet count of 100 × 109/L.
Measured: 3 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will evaluate the safety and effectiveness of a genetically engineered antibody, alemtuzumab (Campath[R]) on patients with myelodysplastic syndrome. MDS is made up of malignant stem cell disorders that can mean low levels of red blood cells-that is, anemia-and low counts of white blood cells and platelets. Patients with MDS are at risk for infection, spontaneous bleeding, and possible progression to leukemia, a cancer of bone marrow. Although bone marrow can produce some blood cells, patients with MDS experience a decrease in production of blood cells. Alemtuzumab recognizes specific types of white cells called lymphocytes and destroys them. This study will examine not only the usefulness of the medication but also the side effects in patients with MDS.
Patients ages 18 to 72 who have MDS that requires transfusions and who do not have HIV or a life expectancy of less than 6 months may be eligible for this study. Screening tests include a complete physical examination and medical history. There will be a collection of about 8 tablespoons of blood for analysis of blood counts as well as liver, kidney, and thyroid function; a pregnancy test; an electrocardiogram (EKG) to measure electrical activity of the heartbeat; an echocardiogram (ECHO), which uses sound waves to evaluate heart function; wearing of a Holter monitor for 24 hours while the electrical activity of the heart is recorded; and a bone marrow biopsy. Patients should not receive any vaccines when taking alemtuzumab or for at least 12 months after the last dose. In addition, patients should not take the herbal supplements Echinacea purpurea or Usnea 2 weeks before beginning the study and during it.
For the study, all patients will receive a test dose of 1 mg of alemtuzumab infused into a vein during the course of 1 hour. If the dose is tolerated, the medication will be given at 10 mg doses into the vein for 10 days, as an infusion of 2 hours. Blood samples of 2 tablespoons will be taken daily, and vital signs will be measured daily. The ECHO and 24-hour Holter monitoring will be repeated after patients receive the last dose of the medication. Because suppression of the immune system results from a decrease in white cells that fight infections, patients will take medications to protect them against infections and to treat them if infections occur. If needed, patients will receive blood transfusions for their MDS. Side effects of alemtuzumab involve a temporarily significant lowering of the number of red blood cells, white cells, and platelets. Side effects of the infusion can be rigidity, or stiffness, and fever, as well as risks of infections resulting from the decrease of white blood cells. Blood counts and reactions to all procedures will be carefully monitored throughout the study. After patients receive the last dose of alemtuzumab, they will have follow-up by their referring doctor or at NIH. They must be able to return to NIH after 1 month, 3 months, 6 months, and annually for 5 years after the study. At follow-up visits, there will be blood tests to reevaluate blood counts and test for the presence of viruses. Blood tests will be done weekly for the first 3 months after patients have completed taking alemtuzumab, every other week until 6 months, and then annually for 5 years. There will also be a repeat ECHO at the 3-month visit, and a repeat bone marrow biopsy at the 5-month and 12-month follow-up visits, and as needed after that.
This study may or may not have a direct benefit for participants. For some, the antibody may improve blood counts and decrease the need for transfusions. Knowledge gained in the study may help people in the future.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Response to Treatment - Hematologic Improvement or Complete Response (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00217594, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2018.
