Active clinical trials for "Lymphoma, T-Cell"

RATIONALE: Combinations of biological substances in alefacept may be able to carry cancer-killing substances directly to cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of alefacept in treating patients with relapsed or refractory cutaneous T-cell lymphoma or peripheral T-cell non-Hodgkin's lymphoma.

The primary objectives of this study are to: establish the safety and dose limiting toxicities of combining alemtuzumab with CHOP chemotherapy for patients with newly diagnosed aggressive T-cell lymphomas; and 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: establish the efficacy of combination alemtuzumab with CHOP chemotherapy; and to measure the effects of combination alemtuzumab with CHOP chemotherapy on T-cell reconstitution and cytomegalovirus (CMV) reactivation.

This study will evaluate the safety and efficacy of LBH489B in adult patients with refractory Cutaneous T-Cell Lymphoma.

This is a Phase II clinical trial aimed at treating a subgroup of patients with cutaneous T-cell lymphoma. The drug consists of a toxin, called diphtheria toxin, which is attached to an antibody that can specifically target cancerous T-cells. Our primary objectives are, therefore, to determine the patient subgroup with respect to disease burden who best responds to this experimental drug in treating CD3 positive T cell malignancies. We will be determining how the patient and their disease respond to this research agent. The Clinical Response Data analysis from October 2014 done at the completion of the Phase I portion of A-dmT390-bisFv(UCHT1) fusion protein clinical trial showed that there were 25 evaluable patients who received all 8 doses varying between 2.5 and 11.25 µg/kg per dose. There were responses at all the lower dose levels up to 7.5 µg/kg per dose. The overall response rate was 36% and the complete response rate was 16% (when followed for 6 months). We have identified a subgroup of CTCL patients that have a very high response rate. If we exclude patients whose mSWAT scores never exceeded 50 (50% of skin surface area times a multiplier) and who never had lymph node involvement or stage III disease we are left with 9 patients. This subgroup has an overall response rate of 89% and a complete response rate of 50% (when followed for 6 months). Of these 4 patients currently in complete remission, three are long-term responders. Two are over 6 years in duration and one over 5 years duration. These may represent cures. The long time periods in the transition from partial response to complete response without treatment, 6 months to two years, suggests that the study drug in addition to exerting a direct killing effect on tumor also functions as an immunomodulator.

This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

This study is designed to determine the recommended dose, safety, pharmacokinetics, and early efficacy of the combination of pralatrexate plus oral bexarotene in patients with relapsed or refractory CTCL.

The goal of this clinical research study is to learn if treatment with two types of chemotherapy combinations can help to control peripheral T-cell lymphoma.

This is a pilot study of the safety and tolerability of photopheresis in combination with increasing doses of oral bexarotene in patients with cutaneous T-cell lymphoma.Our hypotheses are that the combination of bexarotene with photopheresis is safe and that bexarotene will enhance immune response in the setting of extracorporeal photopheresis in the treatment of cutaneous T-cell lymphoma (CTCL), resulting in a shorter time to clinical response.

Nasal/nasal type NK-T-cell lymphoma is a rare and severe type of non-Hodgkin's lymphoma (NHL) more frequent in Asia than in western countries. When localised, radiotherapy seems to be the best treatment. When radiotherapy cannot be used because of dissemination or relapse, chemotherapy protocols used for other types of NHL give poor results and survival is poor. Recently papers from China and Japan reported the efficacy of a drug: l-asparaginase, usually used to treat acute lymphoblastic leukemia. In vitro a selective apoptosis of NK-cell tumours by l-asparaginase was shown on tumour cell lines and samples. The investigators propose a phase II protocol for patients with refractory or relapsing nasal/nasal type NK-T-cell lymphoma using a regimen combining l-asparaginase, methotrexate and dexamethasone. Biological studies will be conducted trying to find factors which could predict responses to this chemotherapy. Since january 2009, the study concerns all patients with nasal/nasal type NK-T-cell lymphoma who have not received asparaginase before.

This phase I multicenter feasibility trial is studying the safety and potential efficacy of infusing ex vivo expanded cord blood progenitors with one unmanipulated umbilical cord blood unit for transplantation following conditioning with fludarabine, cyclophosphamide and total body irradiation (TBI), and immunosuppression with cyclosporine and mycophenolate mofetil (MMF) for patients with hematologic malignancies. Chemotherapy, such as fludarabine and cyclophosphamide, and TBI given before an umbilical cord blood transplant stops the growth of leukemia cells and works to prevent the patient's immune system from rejecting the donor's stem cells. The healthy stem cells from the donor's umbilical cord blood help the patient's bone marrow make new red blood cells, white blood cells, and platelets. It may take several weeks for these new blood cells to grow. During that period of time, patients are at increased risk for bleeding and infection. Faster recovery of white blood cells may decrease the number and severity of infections. Studies have shown that counts are more likely to recover more quickly if increased numbers of cord blood cells are given with the transplant. We have developed a way of growing or "expanding" the number of cord blood cells in the lab so that there are more cells available for transplant. We are doing this study to find out whether or not giving these expanded cells along with one unexpanded cord blood unit is safe and if use of expanded cells can decrease the time it takes for white blood cells to recover after transplant. We will study the time it takes for blood counts to recover, which of the two cord blood units makes up the patient's new blood system, and how quickly immune system cells return
