We propose to evaluate a preoperative education of the patient and a new surgical technique (the mini-invasive THR) that could reduce the time to achieve functional independence. The primary objective of the trial is to assess the time to reach functional independence after total hip replacement depending on the treatment groups: preoperative education versus no preoperative education and mini-invasive procedure versus standard procedure. The study hypothesis is that education and mini-invasive procedure will reduce the time to reach functional independence. This is a prospective trial with a double randomization.
This will be a study of the safety of MSP 3 LSP candidate malaria vaccine in children aged 1-2 years in Burkina Faso. Three imminizations at 28 day intervals will be administratered subcuteneously on the shoulder region. The study will compare MSP3 with Engerix B vaccine to evaluate whether it is just as safe to give to children in malaria endemic country. The study will also evaluate whether the vaccine induces the expected immune responses. Two dose levels of MSP 3 will be evaluated; 15µg and 30µg to determine the one with the best safety and immune response profile.
The purpose of this study is to clarify the relationship bone marrow-derived cells and the formation of the tumors, and the role of these cells in regeneration of epithelial cells in the gastrointestinal tract.
The purpose of this study is to investigate the correlation of SV2A expression in surgically removed tumour and tumour-surrounding tissue of glioma patients suffering from epilepsy with their clinical response to levetiracetam.
A dietary intervention study in patients with Follicular Lymphoma (FL) Stage III/IV to assess the ability of several dietary factors to induce apoptosis, inhibit cell proliferation and modulate tumor cell infiltrate in vivo.
The purpose of this study is to determine the benefits, if any, of combination therapy with Lucentis plus reduced fluence photodynamic therapy with Visudyne.
Patients with coronary artery disease are characterized by an increased cardiovascular risk and they often have low blood high density lipoprotein (HDL)-cholesterol levels or HDL-cholesterol with modified vasculoprotective properties. The purpose of the present study is to characterize the quality of HDL-cholesterol in patients with coronary artery disease and normal blood HDL-cholesterol levels and to examine the effect of exercise training on the vasculoprotective effects of HDL-cholesterol in these patients. Additionally, the researchers aim to investigate the endothelial function, oxidative stress and the regenerative capacity of the endothelial progenitor cells in patients with coronary artery disease and the changes dependent on physical activity of patients.
RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia(HCL) that has not responded to chemotherapy, surgery or radiation therapy. PURPOSE: Phase I dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have hairy cell leukemia (HCL) that has not responded to treatment.
High-dose chemotherapy and autologous stem-cell transplantation have an established role in the treatment of aggressive Non-Hodgkin's lymphoma (NHL) when refractory to first line chemotherapy or after relapse. The PARMA study randomized 109 patients, with chemo-sensitive relapse and no marrow involvement to receive, following the initial salvage regimen, high-dose chemotherapy versus continuous standard dose chemotherapy. 5-year progression-free survival was 46% in the transplant group compared with 12% in the chemotherapy group. Results are significantly inferior in patients with multiply relapsed or chemo-refractory disease with only 0-20% of patients achieving long-term disease control with autologous transplantation. Thus a large proportion of patients with refractory and relapsing disease are not cured with currently available transplantation methods and newer approaches are required. Rituximab is the first monoclonal antibody approved for clinical use. It is an anti CD20 antibody with high response rate in the treatment of follicular lymphoma and increases response rate in aggressive lymphoma when combined with chemotherapy. It is well tolerated with minimal side effects. However tumors may escape rituximab sensitivity by loss of antigen, poor access of antibody to bulky or poorly vascularized tumors, or failure of host effectors to eliminate antibody binding tumor cells. Lymphoma cells are inherently and exquisitely sensitive to radiation. Radioimmunotherapy uses monoclonal antibodies conjugated with a radioactive isotope to target radiation directly to tumor cells. Ibritumomab is the parent murine anti CD20 antibody witch targets the same epitope as rituximab. Tiuxetan is a chelator covalently linked to the antibody which chelates the isotope 90Yttrium to form the active radioconjugate Zevalin. 90Yttrium is a pure high-energy beta emitter with a relatively short half time (64 hours) and a path length of 5 mm. These properties make it an ideal isotope for radioimmmunotherapy. The high energy and long beta path are advantageous in treating bulky, poorly vascularized tumors, and tumors with heterogeneous antigen expression as neighboring tumor cells can be hit by cross fire from tumors binding the radioconjugate. Pure beta emission limits radiation to the patient body and is safe for the surrounding allowing simple outpatient care, no need for patient isolation or shielding. Biodistribution is predictable, eliminating the need for dosimetry. Initial studies showed that Zevalin has a favorable toxicity profile and is more effective than rituximab in patients with follicular and transformed non-Hodgkin's lymphoma, and studies are currently performed in aggressive lymphoma. There are initial phase I-II studies combining radioimmunotherapy with high-dose chemotherapy and autologous stem-cell transplantation with promising results. We conducted a phase II study of fixed-dose Zevalin at 0.4 mCi/kg with BEAM high-dose chemotherapy in patients with chemo-refractory disease. So far, 23 patients were included. With a median follow-up of 17 months the estimated progression-free survival was 52% compared with 0-20% expected in patients with multiply relapsed and chemo-refractory disease. Based on these data and data from other groups we expect that the addition of Zevalin to standard high-dose chemotherapy will improve transplantation outcomes in patients with standard-risk chemosensitive disease, as well. This study will randomize patients to Zevalin-BEAM versus BEAM alone to determine the potential of Zevalin radioimmunotherapy to improve outcome of autologous stem-cell transplantation.
The purpose of this study is to compare the suppressive effect of two kinds of interventions on the worsening/progression to definite diabetes: standard lifestyle guidance and standard lifestyle guidance combined with pharmacological intervention (monotherapy with one of acarbose, metformin, or gliclazide).
