Radiation, Chemotherapy, Vaccine and Anti-MART-1 and Anti-gp100 Cells for Patients With Metastatic Melanoma

Phase II Study of Metastatic Melanoma Using a Chemoradiation Lymphodepleting Conditioning Regimen Followed by Infusion of Anti-Mart-1 and Anti-gp100 TCR-Gene Engineered Lymphocytes and Peptide Vaccines

Background: Melanoma antigen recognized by T-cells (MART-1) and gp100 are two genes found in melanoma cells. An experimental procedure developed for treating patients with advanced melanoma uses these genes and a type of virus to make special cells called anti-MART-1 and anti-gp100 cells, which are designed to destroy the patient's tumor. The cells are created in the laboratory using the patient's own tumor cells or blood cells. The procedure also uses one of two vaccines-the anti-MART-1 peptide or the anti-gp100 peptide-to stimulate cells in the immune system that may increase the effectiveness of the anti-MART-1 and anti-gp100 cells. Both vaccines are made from a virus that is modified to carry a copy of the MART-1 gene or gp100 gene. The virus cannot cause disease in humans. Objectives: - To evaluate the safety and effectiveness of anti-MART-1 and anti-gp100 cells and peptide vaccines for treating patients with advanced melanoma. Eligibility: - Patients 18 years of age with metastatic melanoma for whom standard treatments, including aldesleukin (IL-2) therapy to boost immune response, have not been effective. Design: Participants have an initial evaluation with complete medical history, as well as scans, x-rays, and other tests as directed by researchers. Most of the treatments for this study will be given on an inpatient basis. Before the treatment begins, participants will undergo leukapheresis (removal of selected blood cells) to obtain cells for preparing the anti-MART-1 and anti-gp100 cells, and for later stem cell transplantation. Preinfusion treatment: 5 days of chemotherapy and 2 days of total-body irradiation to prepare the immune system for receiving the anti-MART-1 and anti-gp100 cells. Infusion of cells, followed by IL-2 treatment to improve immune response. IL-2 is given as a 15-minute infusion through a vein every 8 hours for a maximum of 15 doses (over 5 days). After the cell infusion, participants will be divided into two groups and will receive either the gp100 peptide or MART-1 vaccine, given once a week for 3 weeks. Participants will also have stem cell transplantation (from previously collected stem cells) to promote cell survival. Periodic follow-up clinic visits after hospital discharge for physical examination, review of treatment side effects, laboratory tests and scans every 1 to 6 months.

Background: We have engineered human peripheral blood lymphocyte (PBLs) to express a T-cell receptor (TCR) that recognizes human leukocyte antigens (HLAA*0201) restricted epitopes derived from the gp100 or the MART-1 melanoma antigen. We constructed single retroviral vectors that contain both Alpha and Beta T cell receptor (TCR) chains and can mediate genetic transfer of this TCR with high efficiency (greater than 30 percent) without the need to perform any selection. In co-cultures with HLA-A*0201 positive melanomas these TCR transduced T cells secreted significant amount of interferon-gamma (IFN-y) but no significant secretion was observed in control co-cultures. gp100:154-162 TCR or MART-1:27-35 TCR transduced T-cells could efficiently kill HLAA*0201 positive tumors. There was little or no recognition of normal fibroblasts. Adoptive transfer of either of these TCR transferred gene modified peripheral blood lymphocyte (PBL) following a nonmyeloablative lymphodepleting regimen could mediate tumor regression in from 13-30 percent of patients with metastatic melanoma though no complete responses were seen. Objectives: Primary objectives: In cohort 1 and 2, to determine if the administration of both the anti-gp100:154-162 TCR-engineered and anti- MART-1:27-35 TCR-engineered peripheral blood lymphocytes (PBL), aldesleukin and either the gp100:154-162 peptide or the MART-1:26-35(27L) peptide to patients following a chemoradiation lymphodepleting preparative regimen will result in complete tumor regression in patients with metastatic melanoma. In cohort 3 and 4, to determine if the administration of both the anti-gp100:154-162 TCR-engineered and anti-MART-1:27-35 TCR-engineered CD8+ peripheral blood lymphocytes (PBL), aldesleukin and either the gp100:154-162 peptide or the MART-1:26-35(27L) peptide to patients following a chemoradiation lymphodepleting preparative regimen will result in complete tumor regression in patients with metastatic melanoma. Determine whether the administration of the specific vaccine (the gp100:154-162 peptide or the MART-1:26-35(27L) peptide) can increase the persistence of the specific transferred cells (anti-gp100:154-162 TCR PBL, anti-gp100:154-162 TCR CD8+ PBL, the anti-MART- 1:27-35 TCR PBL, or the anti-MART-1:27-35 TCR CD8+ PBL), respectively. Secondary objectives: - Determine the toxicity profile of these treatment regimen. Eligibility: Patients who are HLA-A*0201 positive and 18 years of age or older must have: metastatic melanoma with measurable disease been previously treated with IL-2 for melanoma; normal values for basic laboratory values. Patients may not have: concurrent major medical illnesses; any form of primary or secondary immunodeficiency; severe hypersensitivity to any of the agents used in this study; contraindications for high dose aldesleukin administration. Design: In cohort 1 and 2: Peripheral blood mononuclear cells (PBMC) will be obtained by leukapheresis (approximately 5 times 10(9) cells) and cultured in the presence of anti-CD3 (OKT3) and aldesleukin and separate aliquots will be transduced with the anti-gp100:154-162 TCR and the anti-MART-1:27-35 TCR retroviral vector. Transduction is initiated by exposure of approximately 10(8) to 5 times 10(8) cells to supernatant containing the retroviral vectors. These gp100 and MART-1 TCR transduced cells will be separately expanded and tested for their anti-tumor activity. Once engineered lymphocytes are demonstrated to be biologically active according to the strict criteria outlined in the Certificate of Analysis, patients will receive a chemoradiation lymphocyte depleting preparative regimen consisting of cyclophosphamide and fludarabine and 600 cGy total body irradiation followed by intravenous infusion of ex vivo tumor reactive, gp100 and MART-1 TCR gene-transduced cells plus IV aldesleukin (720,000 IU/kg q8h for a maximum of 15 doses). Patients will be randomized to receive either the gp100:154-162 peptide or the MART-1:26-35(27L) peptide emulsified in incomplete Freund's adjuvant. Patients will undergo complete evaluation of tumor with physical examination, computed tomography (CT) of the chest, abdomen and pelvis and clinical laboratory evaluation four to six weeks after treatment and then monthly for approximately 3 to 4 months or until off study criteria are met. The study will be conducted using a phase II optimal design where initially 21 evaluable patients will be enrolled into each of two cohorts. If none of the 21 patients per cohort experiences a complete clinical response, then no further patients will be enrolled but if 1 or more of the first 21 evaluable patients enrolled in that cohort have a complete clinical response, then accrual to that cohort will continue until a total of 41 evaluable patients have been enrolled in that cohort. Cohort 1 and 2 will be closed with the approval of amendment D. Cohort 3 and 4 will be initiated with approval of amendment D. Peripheral blood mononuclear cells (PBMC) will be obtained by leukapheresis (approximately 5 times 10(9) cells) and CD8+ cells will be selected from the cultures, using the Miltenyi CliniMACS apparatus, prior to being stimulated and transduced. Separate aliquots of CD8+ cells will be transduced with the anti-gp100:154-162 TCR and the anti-MART-1:27-35 TCR retroviral vectors. Transduction is initiated by exposure of approximately 10(8) to 5 times 10(8) CD8+ cells to supernatant containing the retroviral vectors. These gp100 and MART-1 TCR transduced cells will be separately expanded and tested for their anti-tumor activity. Once engineered lymphocytes are demonstrated to be biologically active according to the strict criteria outlined in the Certificate of Analysis, patients will receive a chemoradiation lymphocyte depleting preparative regimen consisting of cyclophosphamide and fludarabine and 600 cGy total body irradiation followed by intravenous infusion of ex vivo tumor reactive, gp100 and MART-1 TCR gene-transduced CD8+ cells plus IV aldesleukin (720,000 IU/kg q8h for a maximum of 15 doses). Patients will be randomized to receive either the gp100:154-162 peptide (cohort 3) or the MART-1:26-35(27L) peptide (cohort 4) emulsified in incomplete Freund's adjuvant. Patients will undergo complete evaluation of tumor with physical examination, CT of the chest, abdomen and pelvis and clinical laboratory evaluation four to six weeks after treatment and then monthly for approximately 3 to 4 months or until off study criteria are met.

Complete response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Complete response is a disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD. Progression is at least a 20% increase in the sum of the LD of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Stable disease is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as reference the smallest sum LD.

Every 4-6 weeks after initial treatment regimen. If the patient has stable disease or tumor shrinkage, complete evaluations will be repeated every 1-3 months.

Here is the number of participants with adverse events. For a detailed list of adverse events, see the adverse event module.
