Filter by:This two-stage, multi-center, randomized, controlled, open-label study will investigate the pharmacokinetics, efficacy and safety of rituximab SC versus rituximab IV in participants with previously untreated follicular non-Hodgkin's lymphoma. Participants will be randomized to receive 375 milligrams per meter square (mg/m^2) rituximab as IV infusion or 1400 milligrams (mg) rituximab SC. In addition, participants will receive standard chemotherapy. Participants who achieved a complete or partial response (PR) after 8 treatment cycles, will receive maintenance treatment for a further maximum number of 12 cycles. Maintenance treatment cycles will be repeated every 8 weeks. This is a two-stage study. Stage 1 was designed to confirm the chosen rituximab SC dose resulting in comparable rituximab serum Ctrough levels compared with rituximab IV, when given as part of induction treatment every 3 weeks. Enrollment for Stage 2 started after the rituximab SC dose was established in Stage 1. Stage 2 aimed to further investigate the efficacy and safety of rituximab SC compared with rituximab IV. The anticipated time on study treatment is 96 weeks.
RATIONALE: Infection prophylaxis and management may help prevent cytomegalovirus (CMV) infection caused by a stem cell transplant. PURPOSE:This clinical trial studies infection prophylaxis and management in treating cytomegalovirus infection in patients with hematologic malignancies previously treated with donor stem cell transplant.
Burkitt lymphoma (BL) is an aggressive monoclonal B-cell malignancy that is rare (sporadic) worldwide, but is 100-fold more common (endemic) in equatorial Africa, particularly among children. Epstein-Barr virus (EBV) and malaria are epidemiologically linked to endemic BL in epidemiologic studies, but questions remain about role of EBV variants and the evidence for association with malaria is weak. EBV is ubiquitous, yet only few children develop BL, possibly because only a few EBV variants are pathogenically relevant. The association of BL with malaria is based on ecologic and non-comparative clinical studies. Two case-control studies have reported significant association of high anti-malarial antibodies with BL (OR=5_ among children in Uganda and in Malawi, but selection bias (cases and controls came from dissimilar geographical areas) and reverse causality bias were limitations. Three studies were conducted in the 1960s and 70s to test association of carriage of malaria-resistance gene with BL, two of which reported a significant or marginal inverse association. These pioneering studies were small (240 cases all together) and looked at one polymorphism in one gene (sickle cell gene). Improvements in technologies to characterize genetic variation allow the EBV and malaria hypotheses to be examined with greater power by looking at genetic variation across multiple genes. Epidemiology of Burkitt lymphoma in East African children and minors (EMBLEM) is a case-control study of 1500 BL cases and 3000 age-, sex- and residence-frequency matched controls we are proposing to conduct in East Africa. The study will enroll cases at four hospitals in four regions in East Africa, where malaria transmission is holoendemic and year round. The controls will be enrolled from general population attendees at Health Center II (HC-II) units where the cases originated. The primary study objectives are: 1) to test the hypothesis that genetic resistance to malaria is associated with a lower risk of BL, and 2) to use genome-wide association methods to discover genetic variation that may be associated with decreased or increased risk of BL. Because genetic variation conveys no information on actual exposure to malaria or EBV, in secondary analyses, we will use empiric epidemiological questionnaire and laboratory methods: a) to measure exposure to malaria and its association with BL, and b) to measure EBV variants and their association with BL. To examine issues related to bias and to obtain data to correct for deviations, we will also enroll 2250 population controls from 5% of the villages to obtain population distribution of key exposures variables. This data will be used to reweight the distribution in HC-II controls back to the general population. ...
This partially randomized phase I/II trial studies the side effects and the best dose of vorinostat when given together with combination chemotherapy and rituximab to see how well it works compared to combination chemotherapy alone in treating patients with human immunodeficiency virus-related diffuse large B-cell non-Hodgkin lymphoma or other aggressive B-cell lymphomas. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Giving vorinostat together with combination chemotherapy and rituximab may kill more cancer cells.
RATIONALE: Monoclonal antibodies, such as ofatumumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. PURPOSE: This randomized phase II trial is studying ofatumumab to see how well it works in treating patients with previously untreated stage II, stage III, or stage IV follicular non-Hodgkin lymphoma.
This is a pilot study, assessing the feasibility, safety and toxicity of an mTOR (mammalian target of Rapamycin) inhibitor (MTI), rapamycin, when administered with HyperCVAD (Hyperfractionated Cyclophosphamide, Vincristine, Doxorubicine and Dexamethasone), with an ultimate goal to perform a phase II study to evaluate response rates and survival in adults with Acute Lymphoblastic Leukemia (ALL) and aggressive lymphoid malignancies.
Current standard treatments for lymphoma involving the central nervous system include chemotherapy or whole brain radiation therapy (WBRT). However, many patients do not respond to this treatment, and some of the patients who do respond relapse after treatment. Previous research has shown that a stem cell transplant of a patient's own cells (autologous stem cell transplant) may be more effective for some patients with lymphoma involving the CNS. In previous research using autologous stem cell transplants for lymphoma involving the CNS, a conditioning regimen consisting of the drugs thiotepa, busulfan and cyclophosphamide (TCE) was used. These drugs have been shown to enter the nervous system. In this research study, the investigators are adding the drug rituximab (Rituxan) to the drug cytarabine for the stem cell mobilization process. Cytarabine is a standard drug for mobilization. In addition, rituximab will be added to the conditioning regimen of thiotepa, busulfan and cyclophosphamide. Rituximab is approved by the FDA for the treatment of some types of lymphomas, but is not approved for use in lymphomas that involve the CNS. Rituximab is known to be able to enter the CNS. Previous research has suggested that it may help treat lymphoma that involves the CNS. The goal of this research study is to see if adding rituximab to the stem cell mobilization and conditioning regimens helps treat lymphoma that involves the central nervous system.
In this study the investigators investigate a cell therapy strategy that could harness allogeneic effectors that can potentially mediate anti-lymphoma effect. The investigators have designed a novel lymphodepleting conditioning regimen followed by infusion of donor-derived natural killer (NK) cells and interleukin-2 (IL-2) for patients with refractory lymphoid malignancies.
This study will compare the effectiveness and safety of two different doses of temsirolimus (Torisel).
The main purpose of this first human study with CC-223 is to assess the safety and action of a new class of experimental drug (dual mTOR inhibitors) in patients with advanced tumors unresponsive to standard therapies and to determine the appropriate dose and tumor type for later-stage clinical trials.
