View clinical trials related to Chronic Lymphocytic Leukemia (CLL).
Filter by:The majority of patients with CLL are diagnosed with early stage disease (Binet stage A or Rai stage 0/I). Standard management of such patients is observation, and with median age at diagnosis of 72 and median time to progression of >5-10 years, many will never require treatment. In contrast, a proportion of patients have more aggressive disease, and over the last decade, a number of molecular factors have been identified that may be used to identify patients with poor prognosis disease . Each is associated with shortened time to treatment (typically less than 3 years in patients with 2 of more factors), reduced survival, with in the case of p53/ATM inactivation, resistance to treatment. Whether it is possible to improve the outcome of patients with CLL and adverse prognostic factors by early intervention with treatment is unknown. Several trials in the 1980's demonstrated that treatment of stage A CLL with conventional chemotherapy (chlorambucil) did not alter the natural history of the disease, although none of these studies stratified patients according to risk. The choice of alternative potential therapeutic agents is limited; they should be effective in patients with adverse prognostic factors, have acceptable toxicity, be able to overcome the drug resistance associated with p53/ATM inactivation and ideally be orally administered. Two recent phase II trials have demonstrated that Lenalidomide is effective in the treatment of relapsed/refractory disease. Importantly, both studies included a high proportion of patients with adverse prognostic factors including p53 inactivation. The principle objective of this study is to investigate the efficacy of Lenalidomide in achieving disease response (complete remission and clearance of minimal residual disease) in patients with poor risk early stage disease, together with assessment of safety and tolerability.
Investigational Drug: Ofatumumab (Azerra) Route of Administration: Intravenous (IV) Hypothesis: This study is designed to assess the toxicity and overall response rate. Ofatumumab is a fully human monoclonal antibody (A type of protein made in the laboratory that can bind to substances in the body, including tumor cells) that shows promising activity in the treatment of CLL as a single agent. It is thought that by combining it with Bendamustine, an FDA approved treatment for CLL, the effect on CLL will be greater than if Ofatumumab is given alone. Participation: Approximately 38 previously untreated CLL subjects will participate in this study over two years. Treatment Plan: A maximum of 6 cycles of treatment will be allowed. During day 1 of cycle 1 ofatumumab IV 300mg will be administered. On day 1 of all cycles ofatumumab treatment will be followed by bendamustine IV 90mg/m2. On day 2 of all cycles, bendamustine IV 90mg/m2 will be administered. On day 3 of all cycles, neulasta SQ 6mg will be given. On day 8 of cycle 1 only patients will receive ofatumumab IV 1000mg. During cycles 2 through 6 ofatumumab 1000mg will be given on day 1 only. Follow-up: Patients will be followed monthly for six months, then every three months for five years then annually thereafter.
Background: - Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: - To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: - Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: - Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. - No treatment will be given as part of this protocol.
Patients with hematologic malignancies will receive myeloablative chemotherapy followed by stem cell rescue with bone marrow or hematopoietic peripheral blood stem cells collected by apheresis from a filgrastim- (G-CSF)-mobilized haploidentical related-donor, ie, hematopoietic peripheral blood stem cell transplant (HSCT).
Patients with chronic lymphocytic leukemia (CLL)have had very poor humoral responses to pneumococcal polysaccharide vaccine (PPV). The vaccine in which pneumococcal polysaccharide antigens are conjugated to protein (PCV) have been immunogenic in CLL patients in our previous studies. The purpose of this study is to evaluate the duration of these vaccine-induced antibodies and the function of memory cells by giving a one dose of PPV-vaccine after several years of PCV-vaccination.
The purpose of the present study is to develop a biological prognostic index in patients with Binet stage A Chronic Lymphocytic Leukemia (CLL) who do not necessitate therapy according to NCI guidelines and to prospectively validate the proposed score system based on the absence/presence of 1, 2 or 3 unfavorable prognostic markers such as cluster of differentiation 38 (CD38) expression, Zap-70 expression and immunoglobulin heavy chain variable region (IgVH) configuration.
The purpose of this registry is to record information on therapy reality of malignant lymphatic systemic diseases by office-based haematologists in Germany.
Subjects are having a bone marrow or SCT for either a type of cancer of the blood called Leukemia or a cancer of the lymph nodes called non- Hodgkin's Lymphoma. Although a transplant can cure leukemia or lymphoma, some people will relapse. In those who relapse, current treatment cures only a very small percentage. Although giving patients a dose of donor immune cells before relapse can prevent relapse of the leukemia or lymphoma, DLI can also cause a serious complication called graft versus host disease (GVHD). This is a gene transfer research study using special immune cells which are specific for these cancer cells. The body has different ways of fighting infection and disease. This study combines 2 of those ways, antibodies and T cells. T cells (CTLs or cytotoxic T cells) are infection-fighting blood cells that can kill cells, including tumor cells. Antibodies and T cells have been used to treat patients with cancers; they have shown promise, but haven't been strong enough to cure most patients. The antibody used in this study is called anti-CD19. This antibody sticks to leukemia cells because of a substance on the outside of these cells called CD19. For this study, the anti-CD19 antibody has been changed so that instead of floating free in the blood it is now joined to T cells. When an antibody is joined to a T cell in this way it's called a chimeric receptor. In the laboratory, investigators found that T cells that are trained to recognize common viruses can stay in the blood stream for many years. By joining the anti-CD19 antibody to CTLs that recognize viruses, they believe that they will also be able to make a cell that can last a long time in the body, provide protection from viruses, and recognize and kill leukemia. The CTLs which we will join the anti-CD19 antibody to attack 3 viruses (trivirus-specific CTLs), CMV, EBV, and adenovirus. Studies have shown that trivirus-specific CTLs grown from the stem cell donor can be given safely to transplant recipients and can stop these viruses from causing severe infections. These CD19 chimeric receptor trivirus specific T cells are an investigational product not approved by the FDA. The purpose of this study is to find the biggest dose of chimeric T cells that is safe, to assess the side effects, to see how long the T cells last and to evaluate whether this therapy might help prevent infections and relapse in people with CD19+ leukemia or lymphoma having a SCT.
This study will assess the - efficacy (response rate) of oral lenalidomide in the treatment of patients with symptomatic, previously untreated, chronic lymphocytic leukemia (CLL), - toxicity of lenalidomide in patients with CLL as well as time to progression, stable disease duration and, if responses are observed, response duration.
