Filter by:This was a phase 1/2, open-label, dose-escalation study of arginine deiminase linked via succinimidyl succinate to polyethylene glycol of 20,000 molecular weight (ADI-PEG 20) in subjects with advanced melanoma. ADI-PEG 20 was administered intramuscularly (IM) at escalating doses weekly for 9 weeks (cycle 1) or 8 weeks (subsequent cycles). The primary objectives were to the establish the safety, tolerability, and clinical efficacy of ADI-PEG 20. Secondary objectives included evaluation of the metabolic activity by [18F]-fluorodeoxyglucose positron emission tomography (FDG PET), pharmacodynamics, correlation of immunogenicity with clinical response, and correlation of argininosuccinate synthetase (ASS) tumor expression with clinical response.
This study is being performed to prospectively determine whether dacarbazine plus Genasense is significantly better than dacarbazine plus placebo in chemotherapy-naive patients with advanced melanoma and low baseline LDH (LDH less than or equal to 0.8 times the upper limit of normal). LDH is a biomarker strongly associated with improved outcomes in a recent trial of dacarbazine plus Genasense.
This was a Phase 2, open-label study of the NY-ESO-1 ISCOMATRIX® (ISCOM) vaccine administered as an intramuscular injection given every 4 weeks to subjects with measurable advanced malignant melanoma. Study objectives included determination of the anticancer activity, cellular and humoral immunogenicity, and safety and tolerability of the NY-ESO-1 ISCOM vaccine administered alone or preceded by a single administration of low-dose cyclophosphamide.
The purpose of this study is to examine the health behaviors of melanoma survivors. We want to know about their thoughts and concerns. Melanoma is a type of skin cancer. The number of people being diagnosed with melanoma is growing. Many people who are diagnosed with melanoma are young. Little research has been done to find out how melanoma survivors feel years after they have been treated.
Background: Sixteen melanoma patients (1 stage IIC, 8 stage III, and 7 stage IV) were treated in a Phase I study to evaluate safety and immune responses, with a vaccine (DC/Apo-Nec) composed of autologous dendritic cells (DCs) loaded with a mixture of apoptotic/necrotic melanoma cell lines (Apo-Nec). Methods: PBMC were obtained from leukapheresis and DCs were generated from monocytes cultured in the presence of GM-CSF and IL-4 in serum-free medium. Immature DCs (iDCs) were loaded with gamma-irradiated Apo-Nec cells and injected id without adjuvant. Cohorts of four patients were given four vaccines with 5, 10, 15, or 20 x106 DC/Apo-Nec per vaccine, two weeks apart. Results: The vaccine was well tolerated in all patients. Toxicity to vaccine was mild, and the toxicity-limiting dose has not been reached. We found that 42.3 ±13.7 % melanoma patients´ iDCs were able to phagocyte Apo-Nec cells wich induced DCs maturation, as evidenced by increased expression of CD83, CD80, CD86, HLA class I and II compared to iDCs. Also, after phagocytosis, a 75.2 ±16 % reduction in Dextran-FITC endocytosis was observed compared to iDCs. CCR7 was upregulated upon Apo-Nec phagocytosis in DCs from all patients and accordingly in vitro DC/Apo-Nec cells were able to migrate towards MIP-3 beta. The DTH score increased significatively in the patients after the first vaccination and slightly decreased by the fourth vaccine (Mann-Whitney Test, p<0.05). For patient #1 a positive DTH reaction was detected to her own tumor irradiated cells. The presence of CD8+ T lymphocytes specific to gp100 and Melan A/MART-1 Ags were studied by tetramers binding in HLA-A*0201 patients (7 /15 patients) before and after vaccination. Two patients who remain NED increased Ags their specific T lymphocytes after vaccination. No humoral responses to Apo-Nec cells were detected. With a mean follow-up of 44.5 months post-surgery, the stage IIC pt is NED, 7/8 stage III pts are NED and 7/7 stage IV patients have progressed. Conclussions: We conclude that DC/Apo-Nec vaccine is well tolerated, it induces specific immunity against melanoma Ags and in stage III patients it may prolong disease-free survival, affording protection from relapse in an adjuvant setting.
RATIONALE: Interleukin-21 may stimulate white blood cells, including natural killer cells, to kill melanoma cells. PURPOSE: This phase II trial is studying the side effects and how well interleukin-21 works in treating patients with metastatic or recurrent malignant melanoma.
Background: - Most therapeutic therapies for metastatic melanoma have focused on the ability of T-cell lymphocytes to kill cells of tumors. - An adaptive cell transfer therapy has been pioneered, in which cells are grown for a short time in the laboratory. The way they are grown may have a better effect in a patient's body than do other cells that are cultured for a longer time. Objectives: - To determine whether tumor-infiltrating lymphocytes (TIL) can be put in cells removed from patients' tumors or blood and then reinfused, with the purpose of shrinking tumors. - To evaluate safety and effectiveness of the treatment. Eligibility: - Patients 18 years of age or older with metastatic cancer melanoma (cancer that has spread beyond the original site). - Patient's leukocyte antigen type is human leukocyte antigens (HLA-A) 0201. Design: -Patients undergo the following procedures: - Leukapheresis (on two occasions). This is a method of collecting large numbers of white blood cells. The cells obtained in the first leukapheresis procedure are grown in the laboratory, and the TIL cells (called young TIL cells) are inserted into the cells using an inactivated (harmless) virus in a process called retroviral transduction. Cells collected in the second leukapheresis procedure are used to evaluate the effectiveness of the study treatment. - Chemotherapy. Patients are given chemotherapy through a vein (intravenously, IV) over 1 hour for 2 days to suppress the immune system so that the patient's immune cells do not interfere with the treatment. - Treatment with young TIL cells. Patients receive an IV infusion of the treated cells, followed by infusions the drug aldesleukin-2 (IL-2), which helps boost the effectiveness of the treated white cells. - Patients are given support medications to prevent complications such as infections. - Patients may undergo a tumor biopsy (removal of a small piece of tumor tissue). - Patients are evaluated with laboratory tests and imaging tests, such as computed tomography (CT) scans, 4 to 6 weeks after treatment and then once a month for 3 to 4 months to determine the response to treatment. - Patients have blood tests at 3, 6, and 12 months and then annually for 5 years.
RATIONALE: Cytotoxic T lymphocytes (CTL) are cells of the immune system that can fight infections and cancer. These CTL can be manipulated in the laboratory so that they can target an individual's cancer. PURPOSE: This early phase trial is studying the feasibility and side effects of intravenous infusions of CTL generated in the laboratory. To produce the CTL, the study participant's own immune cells are collected by a procedure called a leukapheresis. The cells then undergo laboratory processing for three weeks. Part of this processing includes mixing the patients immune cells with a new kind of cell that has some extra genes added to it. These extra genes are to "teach" the participant's own immune cells to become anti-tumor CTL that can attack the melanoma.
Primary Objectives: - To conduct semi-structured interviews with melanoma patients and family members to collect descriptive information on their UVR exposure, UVR exposure-reduction practices, melanoma early detection practices, knowledge, psychosocial variables related to melanoma risk-reduction (e.g., self-efficacy, norms, and expectations), and experiences surrounding the diagnosis of melanoma in the family. Melanoma patients and family members with children will be asked about the UVR exposure and UVR exposure-reduction practices of their children, and parental practices to reduce UVR exposure among children. - To develop behavioral and attitudinal questionnaires based on data collected during semi-structured interviews, and evaluate the appropriateness of these questionnaires using cognitive interviewing techniques. - To develop tailored messages aimed at promoting strategies to reduce UVR exposure (e.g., wearing protective clothing, minimizing midday UVR exposure, minimizing duration of UVR exposure, using shade and sunscreen, avoiding sun lamps, and avoiding intentional tanning) and improving adherence to surveillance and screening guidelines. Messages will be developed to correspond to responses to questionnaire items. - To assess tailored messages for their relevance, appropriateness, attractiveness and appeal, credibility, and perceived behavioral impact among melanoma patients and their family members.
Background: - Human peripheral blood lymphocytes have been engineered to express a T-cell receptor (TCR) that recognizes a blood type,HLA-A 0201 (human leukocyte antigen) derived from the gp100 protein. A retroviral vector was constructed that can deliver the T-cell receptor (TCR) to cells. - Patients' cells will be converted into cells able to recognize and fight melanoma tumors. Objectives: - To determine whether TCR-engineered lymphocytes can be put in cells removed from patients' tumors or blood and then reinfused, with the purpose of shrinking tumors. - To evaluate safety and effectiveness of the treatment. Eligibility: - Patients 18 years of age or older with metastatic cancer melanoma (cancer that has spread beyond the original site). - Patient's leukocyte antigen type is HLA-A 0201. Design: -Patients undergo the following procedures: - Leukapheresis (on two occasions). This is a method of collecting large numbers of white blood cells. The cells obtained in the first leukapheresis procedure are grown in the laboratory, and the anti-MART-1 protein is inserted into the cells using an inactivated (harmless) virus in a process called retroviral transduction.
