Filter by:Background: - Several types of blood cancer are associated with poor outcomes including high-risk myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (CMML) and acute myelogenous leukemia (AML). Many people with MDS, CMML, and AML are not candidates for standard treatments. New types of treatment are needed for these cancers. - Clofarabine and lenalidomide are anticancer drugs. The first damages cancer cells in the body. The second can alter blood supply to abnormal cells or affect how the immune system attacks these cells. These drugs have been previously tested as treatments for MDS and leukemia. However, they have not been tried as a combination for MDS, CMML, and AML. Researchers want to see if these drugs are safe and effective for these types of cancer. Objectives: - To test the safety and effectiveness of clofarabine and lenalidomide for people with high-risk MDS, CMML, and AML. Eligibility: - Individuals at least 18 years of age who have high-risk MDS, CMML, and AML. - Participants must not be candidates for standard treatments. Design: - Participants will be screened with a physical exam and medical history. Blood and bone marrow samples will be collected. - Participants will have 5 days of treatment with clofarabine. It will be given through a vein during an inpatient hospital stay. If there are no serious side effects after the infusion, participants will continue treatment as outpatients. - After 28 days, participants will have a bone marrow biopsy to check their response to treatment. - After the biopsy, participants will start lenalidomide treatment. Half of the participants will take the drug for 28 days (one treatment cycle). The other half will take it for 56 days (two cycles). More blood tests and biopsies will be used to monitor treatment. - If there are no serious side effects and the disease does not become worse, participants may keep taking lenalidomide at lower doses for up to 12 more cycles.
The purpose of this study is to confirm the safety and tolerability of oral panobinostat (PAN) in combination with a fixed dose of 5-Azacitidine (5-Aza) in adult Japanese patients with Myelodysplastic Syndromes (MDS), Chronic Myelomonocytic Leukemia (CMML) or Acute Myeloid Leukemia (AML).
This research study is for subjects that are receiving a bone marrow transplant. As part of the transplant subjects will receive stem cells from a donor who has agreed to donate stem cells for them. Unfortunately, it takes a long time for the immune system to recover after a bone marrow transplant. This makes it more likely for patients to develop serious infections. This study is being done to better understand how the immune system will recover after transplant. The immune system includes the cells that help fight infection. This study will help investigators understand which patients are at risk for developing infections after transplant. All children and adults receive standard vaccines (shots) during their lifetime to provide protection from many different infections. One such infection is tetanus, a bacteria that can cause life-threatening problems. After transplant patients no longer have protection from infections such as tetanus. Therefore, most patients need to receive all their vaccine (shots) again after transplant. This is usually done 1-2 years after transplant, since it may take that long for patients to have a normal immune system. However, the investigators believe that the time it will take for the patient to develop normal protection against tetanus can be shortened if both the patient and the patient's stem cell donor receive a tetanus vaccine. The goal of this study is to determine if giving a tetanus vaccine to the donor and the patient will provide the patient with enough protection (immunity) to prevent infection following bone marrow transplant.
The goals of this study are to learn about the effectiveness, the side-effects, if waiting to give the idarubicin and cytarabine may change the side effects or effectiveness, and to identify factors to predict for responses to this therapy. The trial will examine combination of three chemotherapy drugs. These drugs are decitabine, idarubicin, and cytarabine.
The purpose of the study is to determine whether azacitidine is safe and effective in the treatment of Chinese patients with higher risk Myelodysplastic Syndromes (MDS).
This registry is set up to collect real-world experience in the management of patients with myeloid neoplasms, in particularly in patients with MDS, CMML or AML, treated with hypomethylating agents in Austria and potentially other participating countries. This registry will collect data in a retrospective as well as in a prospective manner at various sites. The aim is to gain valuable insights on both efficacy and toxicity of these drugs in a routine clinical setting in patients with various comorbidities.
This is a Phase II therapeutic trial combining Decitabine days 1-5 with oral Vorinostat twice daily days 6-15 followed by a single infusion of CD3-/CD19- enriched donor natural killer (NK) cells on day 17 and a short course of Interleukin-2 (IL-2) to facilitate NK cell survival and expansion. Two courses of treatment will be given separated by 6-8 weeks. The intent is to administer all treatment in the outpatient setting.
This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.
The primary objectives of this study are to determine if rigosertib sodium, given orally in the form of soft gel capsules, is safe and is associated with a reduction in the number of blood transfusion units that are needed in patients with myelodysplastic syndrome (MDS) classified as Low or Intermediate-1 (Int-1) (any cytogenetics) or trisomy 8 Intermediate 2 (Int-2) in the International Prognostic Scoring System (IPSS) who are transfusion-dependent. Rigosertib will be taken on days 1 to 21 of a 21-day cycle.
5-aza is a chemotherapy drug with activity in leukemia and myelodysplastic syndromes (MDS). Researchers hope that valproic acid (VPA) and all-trans retinoic acid (ATRA)will increase the effects of 5-aza. The goal of this clinical research study is to find the highest safe dose of valproic acid (VPA) that can be given in combination with 5-azacytidine (5-aza) and all-trans retinoic acid (ATRA) in the treatment of AML and MDS. The safety and effectiveness of this combination therapy will also be studied.
