Funded Research

January, 2005: The Brian Morden Foundation and the Liddy Shriver Sarcoma Initiative have joined forces to fund $50,000 for research on a vaccine to treat recurrent and relapsed Ewing's Sarcoma, a rare cancer. The vaccine is being developed by a team of oncology specialists at the University of Michigan Medical Center led by Dr. James Geiger, with Dr. John E. Levine and Dr. Raymond Hutchinson as co-investigators. This study continues an initial Phase I Clinical Trial funded by the National Institutes of Health that Dr. Geiger and his team initiated. Funds from the Brian Morden Foundation and the Liddy Shriver Sarcoma Initiative, in addition to grants from the University of Michigan will allow doctors to offer a new alternative to patients whose traditional chemotherapy and radiotherapy have failed. See the press release.

Vaccine Study Now Underway

A vaccine study jointly sponsored by the Liddy Shriver Sarcoma Initiative and the Brian Morden Foundation is now actively recrutiing patients. The study, "A pilot study of tumor lysate-pulsed dendritic cell vaccine for immune augmentation for high-risk solid tumor patients following autologous stem cell transplantation," is being conducted by James D. Geiger, M.D. (principal investigator) and John E. Levine, M.D. and Raymond J. Hutchinson, M.D. (co-investigators) and will take place at the University of Michigan. Patients with a histologically verified diagnosis of soft tissue sarcoma, including rhabdomyosarcoma, Ewing’s sarcoma family tumors (ES, PNET), synovial sarcoma, fibrosarcoma, or desmoplastic round cell tumor or neuroblastoma and Wilm’s tumor are potential candidates for this study. The details about it follow.

Trial Description

This pilot study will assess whether the experimental tumor vaccine can stimulate the immune system to fight cancer in addition to standard treatment. The study is being conducted primarily to determine the effectiveness of the vaccine to generate an immune response against the tumor, prolonging survival without tumor recurrence and to measure the side effects which occur in association with vaccine use. The study treatment will consist of high-dose chemotherapy followed by infusion of your own peripheral blood stem cells (PBSC) plus the administration of a series of three tumor vaccines.

Purpose

Chemotherapy drugs stop tumor cells from dividing so they stop growing or die. Peripheral blood stem cell transplantation allows the doctor to give higher doses of chemotherapy and thus kill more tumor cells. Dendritic cells are special white blood cells that can potentially stimulate the immune system to kill the remaining tumor cells. It is not yet known if giving dendritic cell tumor vaccines following stem cell transplantation will lead to a better immune response against the tumor.

This is a pilot study to evaluate the ability of tumor lysate-pulsed dendritic cell vaccines to augment the anti-tumor immune response in pediatric and young adult patients with solid tumors after autologous hematopoietic stem cell transplantation. The proposed study will further our understanding of immune responses to solid tumors and the ability of dendritic cell tumor vaccine to modulate the anti-tumor immune response in the post-hematopoietic stem cell transplant recovering immune system.

Eligibility

Eligibility criteria include the following:

Patients may enroll on this study at various points in their treatment including diagnosis, recurrence, or just prior to initiation of study mandated transplant therapy. Because patients may enter this study prior to completion of pretransplant treatments, the below criteria must be met only in order to proceed to the high dose chemotherapy and autologous stem cell transplant of this study. These criteria are not a requirement to enter this study in order to collect tumor or peripheral blood stem cells.

Exclusion Criteria
Treatment / Intervention

Patients will have undergone successful collection of PBSCs for transplant engraftment and generation of dendritic cells. They will then undergo a high-dose chemotherapy conditioning regimen consisting of etoposide, thiotepa, and cyclophosphamide followed by hematopoietic stem cell transplant.

At approximately 28 days following transplant, patients will undergo an array of tests of immune function and start the tumor-pulsed dendritic cell vaccinations. The actual timing of the vaccinations will be based on when the individual patient first achieves a post-transplant absolute lymphocyte count of 200, for three consecutive days.

A series of three vaccinations will be administered to patients at two-week intervals (approximately days +28, +42, and +56). The vaccinations will be administered intradermally into the same arm or leg for all three vaccinations. This will be done on an outpatient basis. Patients will return 2 weeks, 6 weeks, and 12 weeks following their third vaccination (around days +70, +98, and +140) for an array of tests assessing general immune function and tumor-specific immune response and to undergo evaluation for tumor response.
