Depsipeptide to Treat T-Cell Lymphomas Clinical Trials References presented on Clinical Trials Search is not intended to be a substitute for proven healthcare advice, trips or professional assistance by using a real medical. We aren't mDs. Always confer with your physician about Depsipeptide to Treat T-Cell Lymphomas conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Depsipeptide to Treat T-Cell Lymphomas Clinical research trials and Depsipeptide to Treat T-Cell Lymphomas medical trials take place in hundreds of localities across the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectualness of new does drugs. The purpose of the studies / projects is to solve specific human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to discover treatments for all sorts of conditions, such as Depsipeptide to Treat T-Cell Lymphomas. Depsipeptide to Treat T-Cell Lymphomas Clinical Trials and other clinical trials permit volunteers to access healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for without cost, and every now and again they are compensated for their time. Sometimes there is a cost for a Depsipeptide to Treat T-Cell Lymphomas clinical trial. Subjects often receive the most expert healthcare possible for their Depsipeptide to Treat T-Cell Lymphomas condition. Risks are a reality, nevertheless, and could include additional or frequent dr. calls, healthcare dangers (perhaps life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with stern guidelines to protect clinical trials subjects.

Depsipeptide to Treat T-Cell Lymphomas
For Condition: Peripheral T Cell Lymphoma,Cutaneous T Cell Lymphoma
Status: Recruiting
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: This study will test the safety and effectiveness of a new anticancer drug called depsipeptide in treating T-cell lymphomas. Depsipeptide has been shown to kill cancer cells in laboratory studies and to shrink various kinds of tumors in animal models. This study will evaluate the response of T-cell lymphomas to depsipeptide and determine how well patients tolerate the drug over a period of several months. Patients with peripheral T-cell lymphoma and cutaneous T-cell lymphoma (Sezary syndrome and mycosis fungoides) 18 years of age or older may be eligible for this study. Candidates will be screened with a medical history and physical examination, computerized tomography (CT) scans of the chest, abdomen and pelvis, electrocardiogram, blood tests, and possibly a bone marrow biopsy. For the biopsy, the hip area is anesthetized and bone marrow is drawn from the hipbone using a special needle. Participants will receive an intravenous (through a vein) infusion of depsipeptide on days 1 and 5 of each 21-day treatment cycle. The drug will be infused over 4 hours through an arm vein or through a central line (a catheter placed under the skin of the chest or neck and passed into a major vein). This catheter is used to deliver the chemotherapy and to draw blood samples for tests to measure the effects of the drug on the body and on the cancer cells. Patients will be admitted to the hospital for the first treatment cycle. If medically feasible, subsequent cycles will be administered on an outpatient basis. Patients may also be asked to undergo additional tumor biopsies before and after treatment and to have a procedure called apheresis, in which immune cells of the blood are collected. For this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The white cells are removed, and the red cells, platelets and plasma are returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm.
Details: NSC 630176 is a depsipeptide fermentation product from Chromobacterium violaceum that was first isolated by the Fujisawa Company. It has demonstrated potent cytotoxic activity against human tumor cell lines and in vivo efficacy against both human tumor xenografts and murine tumors. NSC 630176, herein referred to as depsipeptide, shows a lack of cross resistance with several commonly used cytotoxic agents such as vincristine, 5-fluorouracil, mitomycin C and cyclophosphamide. However, it has been defined as a P-glycoprotein (Pgp) substrate by COMPARE analysis of the NCI drug screen cytotoxicity profile. Depsipeptide is a member of a novel class of antineoplastic agents, the histone deacetylase inhibitors. A phase I trial of depsipeptide was completed at the NCI. The MTD was found to be 17.8 mg/m(2). The major observed toxicities were granulocytopenia, thrombocytopenia, hypocalcemia, fatigue, nausea and vomiting. In that trial, three responses were observed at the MTD in patients with T-cell lymphomas. Two of the patients had cutaneous T-cell lymphoma and one had peripheral T-cell lymphoma. Because of these observed responses, this phase II study will examine the use of depsipeptide in patients with cutaneous T-cell lymphoma and with peripheral T-cell lymphoma. Patients with cutaneous T-cell lymphoma generally demonstrate some response to cytotoxic agents, however they have a short duration of response. Therefore, in patients with cutaneous T-cell lymphoma, the primary end points to be examined are overall response rate, complete response rate and duration of response. Patients with peripheral T-cell lymphoma do have some durable responses to cytotoxic agents. Therefore, patients with peripheral T-cell lymphoma will be admitted on study after failure of a conventional therapy. The endpoints to be examined will be overall response rate and complete response rate. In addition, the molecular effects of depsipeptide and the tolerability of depsipeptide with extended cycles of therapy will be examined. Our ultimate goal is to use depsipeptide for strategies aimed at the reversal of drug resistance. T-cell lymphomas are good models because they demonstrate a high response rate to many different agents that is generally followed by relapse and treatment failure.
