Filter by:Background: Lymphoma is a type of blood cancer. Blood cell transplant can cure some people with lymphoma. Researchers want to see if they can limit the complications transplant can cause. Objective: To test if a stem cell transplant can cure or control lymphoma. Also to test if new ways of getting a recipient ready for a transplant may result in fewer problems and side effects. Eligibility: Recipients: People ages 12 and older with peripheral T cell lymphoma that does not respond to standard treatments Donors: Healthy people ages 18 and older whose relative has lymphoma Design: Participants will be screened with: Physical exam Blood and urine tests Bone marrow biopsy: A needle inserted into the participant s hip bone will remove marrow. Donors will also be screened with: X-rays Recipients will also be screened with: Lying in scanners that take pictures of the body Tumor sample Donors may donate blood. They will take daily shots for 5 7 days. They will have apheresis: A machine will take blood from one arm and take out their stem cells. The blood will be returned into the other arm. Recipients will be hospitalized at least 2 weeks before transplant. They will get a catheter: A plastic tube will be inserted into a vein in the neck or upper chest. They will get antibody therapy or chemotherapy. Recipients will get the transplant through their catheter. Recipients will stay in the hospital several weeks after transplant. They will get blood transfusions. They will take drugs including chemotherapy for about 2 months. Recipients will have visits 6, 12, 18, 24 months after transplant, then once a year for 5 years.
The aim of this study is to evaluate anti-tumor safety and efficacy of endostar®（Human recombinant endostatin injection）combined with traditional GDP （gemcitabine+dexamethasone+cis-platinum）chemotherapy for newly diagnosed or relapsed PTCL(aggressive peripheral T-cell lymphomas) patients in phase II clinical study.
The purpose of this study is to: - assess the effectiveness of lenalidomide for the treatment of patients with relapsed and or refractory peripheral T-cell lymphomas; and, - assess the safety of lenalidomide. There are reports suggesting a therapeutic benefit of thalidomide in patients with refractory and/or relapsed Non-Hodgkin's Lymphoma's (NHL) which have led to the formal investigation of lenalidomide in the treatment of relapsed NHL's.
The primary objectives of this study are to: 1. establish the safety and dose limiting toxicities of combining alemtuzumab with CHOP chemotherapy for patients with newly diagnosed aggressive T-cell lymphomas; and 2. to measure the pharmacokinetics of alemtuzumab used in different subcutaneous doses and schedules. This will then determine the dose with the highest achievable drug levels with acceptable toxicities worthy of further investigation. The secondary objectives are to: 1. establish the efficacy of combination alemtuzumab with CHOP chemotherapy; and 2. to measure the effects of combination alemtuzumab with CHOP chemotherapy on T-cell reconstitution and cytomegalovirus (CMV) reactivation.
Peripheral T-cell lymphomas (PTCLs) are neoplasias from post-thymic T-cells at different stages of differentiation and are a heterogeneous group of malignancies which present with different morphological patterns, phenotypes, and clinical presentations. These tumours have a striking epidemiological distribution with a lower incidence in Western countries than in Asia. In Korea, PTCLs including T- or natural killer (NK)-cell lymphomas constitute approximately 25 to 35% of all non-Hodgkin's lymphomas. This incidence is quite similar to that of other Eastern Asian countries, including Japan, Hong Kong, and China. Recent studies suggest that the T-cell phenotype is an independent significant prognostic factor, with PTCLs having one of the lowest overall survival and failure-free survival rates. Based on the investigator's experience, the overall complete remission rate was 61.2% (95% confidence interval [CI]: 48.5-72.8%) and the 5-year probability of failure-free survival was 33.5%. Median survival of all patients was 45 months (range 0-64+ months) and the 5-year probability of survival was 36.2%. Rassidakis et al. reported that expression of pro-apoptotic proteins BAX and BCL-XS, may explain the poor response of many types of PTCL to standard chemotherapy. To overcome such poor outcome, the optimal therapy for PTCLs remains to be defined. However, because of the rarity of the disease in Western countries, only a few trials have been reported. Bortezomib (Velcade) is a modified dipeptidyl boronic acid, and a reversible inhibitor of the chymotrypsin-like activity of the 26S proteosome. Bortezomib may induce tumor cell apoptosis or decreased bcl-2 associated drug resistance. Through phase II studies, single agent bortezomib in patients with relapsed indolent and mantle cell lymphomas showed its activity. And also preliminary data indicate that bortezomib can be safely administered in combination with dose adjusted etoposide, prednisolone, vincristine, cyclophosphamide and doxorubicin (EPOCH) chemotherapy. Therefore, it can be possible to improve the poor outcome of patients with PTCLs by a combination of cyclophosphamide, doxorubicin, vincristine, prednisolone (CHOP) with bortezomib as a first-line therapy. Primary Hypothesis: Based on the clinical trials and experimental data, bortezomib can overcome pro-apoptotic proteins BAX and BCL-XS induced drug resistance.
