• A Phase 2 Study of Ipilimumab in Children and Adolescents (12 to < 18 years) with Previously Treated or Untreated, Unresectable Stage III or Stage IV Malignant Melanoma Rochester, MN The purpose of the study is to comply with the Pediatric Investigation Plan requirements of Ipilimumab
• Allogeneic Stem Cell Transplantation for Patients with Severe Aplastic Anemia, Using Matched Unrelated Donors and Mismatched Related Donors Rochester, MN

  For patients with severe aplastic anemia (SAA) who have failed to respond to immunosuppressive therapy and lack an HLA identical family member, our objectives are to make an initial assessment of the safety and efficacy of allogenic stem cell transplantation from either a matched unrelated donor or a mismatched reacted donor using the conditioning regimen of Cytoxan, reduced total body irradiation (TBI) and Campath IH. The principle measures of safety and efficacy will be :

  1. Patient survival probability at 100 days, 1 year and 2 years.
  2. Incidence of graft versus host disease (GVHD), as well as incidence of acute GVHD and chronic GVHD within 6 months and 2 years.
  3. Engraftment at 6 months, 1 year and 2 years
• Killer Immunoglobulin-like Receptor (KIR) Incompatible Unrelated Donor Hematopoietic Cell Transplantation (SCT) for AML With Monosomy 7, -5/5q-, High FLT3-ITD AR, or Refractory and Relapsed Acute Myelogenous Leukemia (AML) in Children: A Children's Oncology Group (COG) Study Rochester, MN

  RATIONALE: Giving chemotherapy before a donor stem cell transplant using stem cells that closely match the patient's stem cells, helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin before transplant and cyclosporine, tacrolimus, and methotrexate before and after transplant may stop this from happening.

  PURPOSE: Natural Killer (NK) cells from the donor's bone marrow may be important in fighting leukemia. Bone marrow donors can be selected based on the type of NK cells they have, specifically the killer immunoglobulin receptor (KIR) type. This study provides information on KIR type from potential donors, which can be used in selecting the bone marrow donor. This phase II trial of unrelated donor stem cell transplant in patients with high risk AML (monosomy 7, -5/5q-, high FLT3-ITD AR, or refractory or relapsed AML) in which KIR typing of the patients and potential donors will be available to the treating transplant physician at the time of donor selection.
