CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma Clinical Trials Info presented on Clinical Trials Search is not intended to be a substitute for certified medical advice, visits or professional assistance using a real physician. We are not physicians. Always consult your dr. about CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma conditions. Clinical Trials Search.org is a site dedicated to listing clinical research studies in human subjects. CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma Clinical research trials and CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma health trials happen in many of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically measure the effectualness of new drugs. The function of the studies / projects is to resolve particular human medical questions. Clinical trials are a popular manner for mDs, government agencies, and private sector corporations to discover remedies for all varieties of circumstances, like CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma. CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma Clinical Trials and other clinical trials allow volunteers to obtain healthcare treatment options before they are available to the masses. Some times the participants undergo professional assistance for free of charge, and occasionally they are paid for their time. Sometimes there is a cost for a CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma clinical trial. Human subjects often get the best healthcare available for their CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma condition. Dangers are a reality, however, and may include additional or frequent mD visits, healthcare dangers (potentially life-jeopardising), and/or the treatment being ineffectual. Trials are federally governed with rigorous guidelines to protect clinical trials patients.

CTLA-4 Antibody (MDX-010) Plus Interleukin-2 to Treat Advanced Melanoma
For Condition: Melanoma
Status: Recruiting
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: This study will determine the highest dose of MDX-010 that can safely be given in conjunction with interleukin2 (IL-2) to patients with advanced melanoma, and to examine its effectiveness against the cancer. MDX-010 is designed to increase immunity to cancer. It is a laboratory-produced antibody to the CTLA-4 protein found on certain lymphocytes (a type of white blood cell). When lymphocytes recognize a foreign substance, such as a virus or bacteria, they initiate an immune response to fight and control the infection. Once this is achieved, CTLA-4 proteins help stop the immune response, decreasing the number of immune cells against the virus or bacteria. When an immune response is mounted against tumor cells, however, it may be beneficial not to stop the immune response, but instead, to keep a large number of lymphocytes available to recognize and fight tumor cells. In this study, MDX-010 will be used to block CTLA-4 and maintain immune activity. IL-2 is a naturally occurring substance whose main function is to signal immune cells to become active. FDA has approved IL-2 for treating patients with advanced melanoma and kidney cancer. Patients 16 years of age and older with stage IV melanoma (melanoma that has spread to the lymph nodes or other sites) and whose tumor is not responding to standard treatments may be eligible for this study. Each candidate will be screened with a history, physical examination, blood test, and electrocardiogram (EKG). X-rays and scans will be done to evaluate the size and extent of their tumor, if current ones are not available. Participants will receive up to four MDX-010 treatments 21 days apart. Each treatment consists of a dose of MDX-010 given intravenously (through a vein) via a catheter (thin plastic tube) over 90 minutes. IL-2 will also be given after the second and third injection of MDX-010 through a small catheter over a 15-minute period every 8 hours for as many doses as are tolerated. In addition to treatment, patients will have the following tests and procedures: - Blood tests before and during the first injection of MDX-010 and blood tests before, during and for 6 days after the second injections of MDX-010 to measure levels of the antibody, and then blood tests every 21 days (every treatment visit) to examine the body's reaction to the treatment. -Leukapheresis to study the effects of treatment on the immune system. For this procedure, blood is drawn through a needle in an arm vein and circulated through a machine that separates the blood into its components (red cells, white cells, platelets, and plasma). The lymphocytes are extracted and the rest of the blood is returned to the patient through a needle in the other arm. Leukapheresis is done just before beginning treatment and may be repeated about three weeks after the fourth treatment. - Biopsy of normal skin and tumor or lymph node to examine the effects of antibody on the immune cells in the tumor. For this procedure, a needle is put into the skin or tumor and a small amount of tissue is pulled out with the needle. Biopsies are optional; they are not required for participation in the study. - Follow-up visit 3 weeks after the fourth treatment for a checkup examination, scans and X-rays, and blood tests. Patients will be watched closely for treatment side effects. Those who develop severe drug side effects, whose bodies develop an immune reaction against the MDX-010 antibody, or whose conditions worsen during treatment may be withdrawn from the study. Those whose tumors have stabilized or shrunk will continue follow-up visits.
Details: This is an open-label study of a human monoclonal antibody (mAb) to CTLA-4 (MDX-010) administered with interleukin-2 to patients with measurable metastatic melanoma who have not previously received high dose IL-2. Patients will be enrolled to escalating dose levels of MDX-010 given in combination with high-dose IL-2 to determine the maximally tolerated dose. When the MTD is determined, the efficacy will be assessed in a standard Phase II fashion.

Hemoglobin greater than or equal to 10 g/dl. Hematocrit greater than or equal to 30%. Creatinine less than or equal to 2.0 mg/dl. AST less than or equal to 3 x ULN (unless definitely attributable to disease). Bilirubin less than or equal to 1.0 x ULN (unless definitely attributable to disease) [except patients with Gilbert's Syndrome, who must have a total bilirubin less than 3.0 mg/dl]. HbsAg is negative. HIV is negative. Anti-HCV is nonreactive. EXCLUSION CRITERIA: Patients will be excluded who have any of the following: Any other prior malignancy, except for the following: adequately treated basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix, or any other cancer from which the patient has been disease-free for five (5) years or more. Autoimmune disease (including uveitis and autoimmune inflammatory eye disease) prior to the study. Active infection, this includes positive results from HIV, HbsAg and anti-HCV. Pregnancy or nursing. Any underlying medical condition which, in the opinion of the principal investigator, will make the administration of study drug hazardous or obscure the interpretation of adverse events. Any concurrent medical condition requiring the use of systemic or topical corticosteroids or the use of immunosuppressive agents (e.g. cyclosporin and its analog, or chemotherapy agents). All corticosteroid use must have been discontinued greater than or equal to four (4) weeks prior to trial entry. Prior treatment with MDX-010 or high-dose IL-2. Evidence or history of significant cardiac, pulmonary, hepatic, renal, psychiatric or gastrointestinal disease that would make the administration of high-dose IL-2 unsafe.
