Filter by:The investigators have previously shown that depletion of CD4+CD25+FoxP3+ regulatory T cells (Treg) enhances the alloreactivity of T lymphocytes, as attested by an accelerated GVHD after allogeneic hematopoietic stem cell transplantation (HSCT) in mice. The investigators thus propose a clinical trial to test whether Treg-depleted donor lymphocytes infusion (dDLI) could induce an improved graft-versus-tumor (GVT) effect in patients refractory to standard DLI (stdDLI) for treatment of relapse after HSCT.
For relapsed acute promyelocytic leukemia after all-trans retinoic acid (ATRA) and arsenic treatment, remission can be achieved by chemotherapy with ATRA and/or arsenic and addition of mylotarg. Autologous hematopoietic cell transplantation using a polymerase chain reaction (PCR) negative graft is important treatment option to obtain sustainable remission. This study is to test the efficacy and the safety of conditioning regimen with idarubicin and busulfan for relapsed Acute Promyelocytic Leukemia (APL).
The objective of the trial was to evaluate the efficacy of the association of topotecan and lapatinib in patients who failed first line platinum-based chemotherapy within 12 months.
This is a non-randomized, open-label study examining the safety and efficacy of betaine in addition to standard anti-viral therapy in genotype 1 hepatitis C non-responders or relapsers to previous pegylated interferon plus ribavirin. Betaine (20 gm/day) in 2 divided doses will be added to Peginterferon alpha 2a (180 mcg) plus weight-based Ribavirin (1000 or 1200 mg/day, for body weight < or > 75 kg, respectively, for 48 weeks. Patients must be diagnosed with chronic hepatitis C, genotype I, and have undergone therapy for hepatitis C with pegylated interferon plus ribavirin. Subjects will be followed for safety, tolerability, hepatitis C viral response and the effect on interferon gene signaling in peripheral blood mononuclear cells during therapy.
The purpose of this research study is to evaluate a new investigational drug (TPI 287) for neuroblastoma and medulloblastoma both alone and in combination with temozolomide (a currently approved drug). An investigational drug is one that has not yet been approved by the Food and Drug Administration. This investigational drug is called TPI 287. This study will look at the safety and tolerability of TPI 287 both alone and in combination with temozolomide, and look to establish a safe dose of this agent. The study will also look at the tumor's response to these drugs, but this is not the primary objective of this study. TPI 287 was shown to be effective in stopping tumor growth and was also shown to be safe in three different animal species. TPI 287 has been tested in humans in four clinical trials, and approximately 100 subjects with various types of cancers have received the drug. All of these subjects that have received TPI 287 have been adults. TPI 287 has not been tested in a pediatric population before this study. Temozolomide was tested in recurrent neuroblastoma and showed activity in a recently published study. Preclinical studies of TPI in combination with temozolomide have shown at minimum an additive effect. The ability of temozolomide and TPI 287 to be effective in combination is suggested by these two drugs showing even greater activity when used together.
The purpose of this study is to assess the safety/tolerability and determine the Japanese recommended dose (RD) of bortezomib administered as a once-daily intravenous bolus twice weekly for 2 consecutive weeks(Days 1, 4, 8, and 11) followed by a 10-day rest period (Days 12 to 21) in Japanese patients with relapsed or refractory multiple myeloma.
The purpose of this research study is to determine whether Carvedilol, an FDA approved beta blocker, when administered for an 8-week period to veterans currently undergoing treatment for methamphetamine dependence (1) improves their ability to stay in treatment longer, (2)eases the aversive symptoms that accompany stimulant withdrawal, and (3) increases the time they remain abstinent from methamphetamine.
Patients have a type of lymph gland cancer called HD, NHL or lymphoepithelioma (these 3 diseases will be referred to as "Lymphoma"). The lymphoma has come back or has not gone away after treatment. This is a research study using special immune system cells called TGFb-resistant LMP-specific cytotoxic T lymphocytes (DNR-CTL), a new experimental therapy. Some patients with Lymphoma show signs of infection with the Epstein Barr virus (EBV) before or at the time of their Lymphoma diagnosis. EBV is found in the cancer cells of up to 1/2 the patients with Lymphoma, suggesting it may play a role in causing Lymphoma. The cancer cells infected by EBV are able to hide from the body's immune system and escape being killed by releasing a substance called Transforming Growth Factor-beta (TGFb). The investigators want to see if special white blood cells (called T cells) that have been given a gene that they hope will let them survive against TGFb and that have been trained to kill EBV infected cells can also survive in the blood and kill the tumor. Investigators have used this sort of therapy with specially trained T cells to treat a different type of cancer that occurs after bone marrow and solid organ transplant called post transplant lymphoma. In this type of cancer they were able to successfully prevent and treat post transplant lymphoma. However when they used a similar approach in HD some patients had a partial response to this therapy, but no patients had a complete response. In a follow-up study they tried to find out if they could improve this treatment by growing T cells that recognize 2 of the proteins expressed on Lymphoma cells called LMP-1 and LMP2a. These special T cells were called LMP-specific cytotoxic T-lymphocytes (CTLs). Although some patients had tumor responses, CTL therapy alone did not cure those who had a lot of disease. Investigators think that a reason for this is that the tumor cells are releasing TGFb. For this reason, they want to find out if they can make the CTL resistant to TGFb by putting in a new gene called TGFb resistance gene. Investigators hope that this will improve this treatment for relapsed lymphoma. These TGFb-resistant LMP-specific CTLs are an investigational product not approved by FDA. The purpose of this study is to find the largest safe dose of TGFb resistant LMP-specific CTLs, to learn what the side effects are and to see whether this therapy might help patients with Lymphoma.
This is a multi-center, open label, uncontrolled, non-comparative phase I/II study in patients with refractory or relapsed multiple myeloma who are eligible for second, third, or fourth line therapy. Patients will be enrolled sequentially into four dose cohorts. The feasibility of administrating Revlimid (R) in combination with Doxorubicin and Dexamethasone (AD) and the MTD of the combination will be determined in the phase I part of the study (Part A). When the MTD has been established, the efficacy of the combination will be further evaluated in the phase II part of the study Part B)
The aim of this study is, to compare the relapse rate in chronic HCV patients with genotype 1 or 3 under the combination of standard dose Peg-Interferon alfa-2a (PEG-IFN alfa-2a), Ribavirin (RBV) and Amantadine (AMA) given for 72 weeks (group A), versus the same combination, given for 48 weeks (group B) in patients who relapsed to previous combination therapy to conventional or pegylated (PEG) Interferon alfa and Ribavirin. Relapse ist defined as percentage of patients with non-detectable HCV-RNA at end of therapy (week 48 GT1/ week 24 GT 3) who become HCV-RNA positive during a follow-up period of 24 weeks.
