7 Clinical Trials for Various Conditions
This phase I trial studies the side effects and best dose of lenalidomide when given together with usual combination chemotherapy (etoposide, prednisone, vincristine sulfate \[Oncovin\], cyclophosphamide, and doxorubicin hydrochloride \[hydroxydaunorubicin hydrochloride\], or "EPOCH") in treating adult T-cell leukemia-lymphoma. Lenalidomide may help shrink or slow the growth of adult T-cell leukemia-lymphoma. Drugs used in chemotherapy, such as etoposide, vincristine, cyclophosphamide, and doxorubicin, 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. Anti-inflammatory drugs such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Giving lenalidomide and the usual combination chemotherapy may work better in treating adult T-cell leukemia-lymphoma compared to the usual combination chemotherapy alone.
This phase II trial studies how well nivolumab works in treating patients with peripheral T-cell lymphoma that has come back after a period of improvement or that does not respond to treatment. Monoclonal antibodies, such as nivolumab, may block cancer growth in different ways by targeting certain cells.
This phase II trial studies how well nivolumab works in treating patients with human T-cell leukemia virus (HTLV)-associated T-cell leukemia/lymphoma. Nivolumab is an antibody, which is a type of blood protein that tags infected cells and other harmful agents. Nivolumab works against a protein called programmed cell death (PD)-1 and may help the body destroy cancer cells by helping the immune system to keep fighting cancer.
RATIONALE: Human T-cell lymphotropic virus type 1 (HTLV-1) can cause cancer. Zidovudine is an antiviral drug that acts against the human T-cell lymphotropic virus type 1. Giving zidovudine, interferon alfa-2b, and PEG-interferon alfa-2b together may stimulate the immune system and slow down or keep the cancer cell from growing. PURPOSE: This clinical trial is studying how well giving zidovudine together with interferon alfa-2b and PEG-interferon alfa-2b works in treating patients with human T-cell lymphotropic virus type 1-associated adult T-cell leukemia/lymphoma.
HTLV stands for human T cell leukemia virus. HTLV-1 is a virus that attacks specific kinds of white blood cells called T cells. T cells are part of the natural defense system of the body. HTLV-1 has been associated with leukemia and lymphoma. In addition, approximately 1% of all patients infected with HTLV-1 develops a condition known as HTLV-1 associated myelopathy (HAM) / tropical spastic paraparesis (TSP). Currently there is no clearly defined, effective treatment for patients with HAM/TSP. Steroids have been used as therapy but have only been able to provide temporary relief of symptoms. Human interferon is a small protein released from different kinds of cells in the body. Interferon has been known to have antiviral and immunological effects and has been used to treat hepatitis and multiple sclerosis. Interferon Beta is released from cells called fibroblasts. These cells play a role in the production of connective tissue. The purpose of this study is to evaluate the possible role of recombinant interferon beta (Avonex) in treatment of HAM/TSP. The study is broken into three phases, a pre-treatment phase, a treatment phase, and a post-treatment phase. The total duration of the study will be 44 weeks. Patients participating in this study will receive injections of Avonex 1 to 2 times a week. Throughout the study patients will regularly submit blood samples and undergo diagnostic tests such as MRI and measures of somatosensory evoked potentials.
Background: - Human T-cell lymphotropic virus type 1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) is an infection of the spinal cord. The infection is caused by a virus that has been known to cause cancers like leukemia and lymphoma. It causes a weakening of the legs. Researchers want to see if raltegravir, a drug for treating human immunodeficiency virus (HIV), can be used to treat HAM/TSP. They will see if the drug can reduce the amount of virus in the blood of people with HAM/TSP. Objectives: - To see if raltegravir can reduce the viral load of people with HAM/TSP. Eligibility: - Individuals at least 18 years of age who have HAM/TSP. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. Imaging studies will be performed. A lumbar puncture will also be taken. * Participants will take the study drug twice a day for 6 months. They will note each dose in a study diary, as well as any side effects. * At the 6-month visit, participants will stop taking the study drug. They will have a physical exam and blood samples, as well as other tests. * Participants will have two further exams 9 months and 15 months after starting the study drug. They will have a physical exam and blood samples, as well as other tests.
Objective: Human T-lymphotropic virus type-I-associated myelopathy / tropical spastic paraparesis (HAM/TSP) is a rare neurologic disorder that affects less than 5% of patients infected with the HTLV-I virus. The purpose of this protocol is to study the natural history of HAM/TSP by monitoring clinical progression of patients longitudinally. Additionally, we will attempt to define the virological and immunological changes of HAM/TSP. Study Population: Patients with HAM/TSP who fulfill World Health Organization diagnostic criteria are eligible to participate in this protocol. Asymptomatic seropositive individuals and individuals with indeterminate HTLV-1 serology are also eligible to participate. Design and Outcome Measures: A longitudinal assessment of clinical, virological and immunological progression in HAM/TSP will be accomplished through periodic testing and evaluation. Asymptomatic seropositive individuals, those with seroindeterminate HTLV-I serology and normal volunteers may serve as controls. Longitudinal standardized neurological examinations will be performed. Longitudinal samples of serum, plasma, and lymphocytes may be obtained from participants. Lumbar punctures may be performed on all participants. These samples will be used virological and immunological assays. A focus is on the relationships between the characteristics of viral infection, the immune response, and the genetic makeup.
