Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients 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 Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients Clinical research trials and Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients 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 Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients. Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients 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 Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients clinical trial. Subjects often receive the most expert healthcare possible for their Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients 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.

Autologous T Cell Immunotherapy for Chronic Lymphocytic Leukemia (CLL) Patients
For Condition: Chronic Lymphocytic Leukemia
Status: No longer recruiting
Sponsor(s): Xcyte Therapies ,
Synopsis: Patients will have immune cells collected and then expanded outside of the body. Patients will receive an infusion of a large number of expanded immune cells. There will be three dose levels studied. The goal of the study will be to determine the safety as well as potential efficacy of this treatment.
Details: This is a Phase I/II single arm dose escalation study of a novel T cell immunotherapy for chronic lymphocytic leukemia (CLL). Patients will receive one dose of Xcellerated T Cells(tm), an ex vivo activated and expanded autologous T cell product, in an attempt to enhance immune responses with anti-tumor activity. This study is being conducted to test the safety and determine the maximum tolerated dose (MTD) of Xcellerated T Cells in patients with CLL. In addition, lymphocyte counts, lymph node area, and quantitative immunoglobulins will be assessed for preliminary evidence of a therapeutic effect. In correlative studies, changes in the phenotype of T and B lymphocytes will be evaluated by flow cytometry. Changes in T cell repertoire and anti-tumor immune activity will also be assessed. It is expected that 12 to 18 patients will be treated.
Eligibility:
Study Type: Interventional, Treatment, Non-Randomized, Open Label, Dose Comparison, Single Group Assignment, Safety/Efficacy Study
Minimum Age/Maximum Age: 18 Years/
Genders: Both
Protocol Entry Criteria: Inclusion criteria: - Diagnosis of CLL at any time in the past, as defined by all of the following: > 5 x 109 peripheral blood lymphocytes/L which are positive for CD5 and one or more B cell markers (CD19, CD20, CD23). < 55% of lymphocytes identified as prolymphocytes - Intermediate or High Risk disease as defined by the Modified 3-stage system - Patients with Intermediate Risk (Rai Stages I and II) must have active disease, as determined by one or more of the following criteria: 1) One or more of the following disease related symptoms i. Weight loss > 10% within the previous 6 months ii. Fevers of greater than 100.5°F for > 2 weeks iii. Night sweats without evidence of infection 2) Massive (i.e. > 6 cm below the left costal margin) or progressive splenomegaly 3) Massive lymph nodes or clusters (i.e. > 10 cm in longest diameter) or progressive lymphadenopathy 4) Progressive lymphocytosis with an increase of >50% over a 2-month period, or an anticipated doubling time of less than 12 months - T cells (CD3+) comprising > 1.5% and < 10 % of peripheral white blood cells as assessed by flow cytometry - CD4+/CD8+ of > 0.30, as assessed by flow cytometry - Age of at least 18 years - ECOG performance status of 0 to 2 - Life expectancy 6 months - Able to comprehend and provide signed informed consent - Women of childbearing potential must have a negative serum pregnancy test and agree to use a medically accepted form of contraception from the time of initial screening through completion of the study Exclusion Criteria - Evidence of Richter’s Syndrome, T cell CLL, prolymphocytic leukemia, hairy-cell leukemia, splenic lymphoma with villous lymphocytes, large granular lymphocytosis, Sezary-cell leukemia, adult T-cell leukemia/lymphoma, or leukemic manifestations of non-Hodgkin’s lymphoma - Receipt of any chemotherapy, monoclonal antibody, investigational, or other systemic therapy for the treatment of CLL within 2 months prior to registration. - Receipt of glucocorticoids (with the exception of inhaled glucocorticoid steroids for the use of allergic rhinitis or pulmonary disease) within 2 months prior to registration - Receipt of intravenous immunoglobulin (IVIG) within 1 month of registration - Registration for, or plans to participate in, any other clinical trial concurrently for the duration of this trial - History of malignancy other than CLL within five years of registration, except adequately treated basal or squamous cell skin cancer or in situ carcioma of the cervix. Other exceptions must be approved by the Xcyte Therapies’ Medical Monitor prior to registration. - Infection requiring treatment with antibiotics, antifungal, or antiviral agents within seven days of registration - Liver disease or hepatitis as reflected by a serum bilirubin or ALT > 2.0 times the upper limit of normal laboratory range within 15 days of registration - Compromised renal function as reflected by a serum creatinine > 2 times the upper limit of normal laboratory range within 15 days of registration - History of autoimmune disease unrelated to CLL (e.g., rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosis). Autoimmune disease related to CLL, e.g. idiopathic thrombocytopenic purpura (ITP) or autoimmune hemolytic anemia, is permitted if treatment with steroids has not been required in the two months prior to registration. Hypothyroidism without evidence of Grave’s Disease or Hashimoto’s thyroiditis is permitted. - Major organ system dysfunction including (but not limited to): New York Heart Association Class III or IV (Appendix B, page 51), pulmonary disease requiring the use of inhaled steroids or bronchodilators, renal, hepatic, gastrointestinal, neurologic, or psychiatric dysfunction which would impair patient’s ability to participate in the trial - Evidence of infection with HIV 1 or 2, HTLV 1 or 2 - Evidence of acute or active chronic Hepatitis B or C infection - Positive human anti-mouse antibody (HAMA) test as performed at the central reference laboratory designated by the sponsor
