Allo Non-Myeloablative SCT Utilizing Mis-Matched Family Member Stem Cells Purged Using Campath

2 mei 2014 bijgewerkt door: David Rizzieri, MD

Allogeneic (Allo) Non-Myeloablative Stem Cell Transplantation (SCT) Utilizing Mis-Matched Family Member Stem Cells Purged Using Campath-1H

Allogeneic transplantation is used to treat many malignant and non-malignant diseases, though the potential toxicities of the procedure remain high. We and others have shown that a less toxic preparative regimen allows reliable allogeneic engraftment for allogeneic transplantation.

The primary purpose of this treatment trial is to follow patients undergoing allogeneic transplantation for long term outcomes. The regimen used has been tested in our prior phase I / II trial which has completed accrual. The issues of engraftment and rate of graft versus host disease have been answered and our success has led to this regimen being a standard approach for less toxic allogeneic therapy.

Gedetailleerde beschrijving

Allogeneic bone marrow transplantation may cure or ameliorate illnesses of many types; however the toxicity of the procedure limits its broad applicability. Hematologic malignancies of all types have shown responses. Those with marrow failure, such as aplasia, and hemoglobinopathies have further shown responses in multiple trials as well. Even patients with certain solid tumors, such as breast, renal cell, and melanoma have shown partial or complete responses to allogeneic therapy. The limiting effect of the historical methods of aggressive induction for allogeneic therapy were extremely toxic, requiring limiting those offered allogeneic therapy to the healthiest of the ill patients. Work over the last decade has shown that less toxic agents targeting the immune system effectively allowed engraftment with less effects on the patient's liver, lungs, and other vital organs. We and others have completed multiple trials showing the effective use of these less toxic, non-myeloablative, regimens for allogeneic therapy. Trials with fludarabine and cyclophosphamide at standard doses (patients are not ablated and recover blood counts in 2 weeks) allow for 80% of patients to engraft donor cells. Some groups have added low doses of radiation to this combination, with 80-100% allogeneic engraftment. The lessened toxicity of this approach has been confirmed in multiple studies, including our own data with the specific schema in this treatment plan reviewed below. Phase I results with this combination: Our group has combined the above combination of fludarabine and cyclophosphamide with the antibody CAMPATH 1H. This antibody is given to the patient to purge the immune system and prevent rejection. It also purges the T cells in the donated stem cells to minimize graft versus host disease (GVHD). This approach has been proven successful in multiple trials using standard more toxic ablative procedures. Our approach over the last 3 years has been very successful using this antibody with the less toxic non-myeloablative procedure and our trials have completed.

The primary purpose of this treatment trial is to follow patients undergoing allogeneic transplantation for long term outcomes. The regimen used has been tested in our prior phase I / II trial which has completed accrual. The issues of engraftment and rate of graft versus host disease have been answered and our success has led to this regimen being a standard approach for less toxic allogeneic therapy.

Beschrijving

Inclusion Criteria:

  • Patients must have their pathology reviewed and the diagnosis confirmed.
  • Performance status (PS) must be Cancer and Leukemia Group B (CALGB) PS 0, 1, or 2
  • Patients must have a 3-5/6 Human leukocyte antigen (HLA)-matched related donor who is evaluated and deemed able to provide peripheral blood progenitor cells (PBPCs) and/or marrow by the transplant team.
  • HIV antibody negative.
  • Patients must test negative for serum beta-human chorionic gonadotropin (hCG) and must agree to use some form of adequate birth control during the periods they receive chemotherapy and any post-chemotherapy medications related to the transplant.
  • Patients must be 17 years of age or greater.
  • Patients must also have a resting Multi Gated Acquisition Scan (MUGA) and/or echocardiography (ECHO) and pulmonary function tests (PFTs) with testing of diffusing capacity of the lung for carbon monoxide (DLCO) performed before transplant and found to be acceptable according to the treating institution's guidelines. The required minimum standards include MUGA and/or ECHO showing an ejection fraction (EF) of 40% and PFTs showing DLCO of 40%. Those with an EF 40-50%, undergo cardiac evaluation and consultation. Also, those with DLCO 40-50%, undergo pulmonary evaluation and consultation.

  • Specific populations for each disease category:

    • Hematologic malignancies Those with high risk or relapsed hematologic malignancy (including myeloid and lymphoid leukemias and lymphomas, myeloma or myelomatous like diseases, myeloproliferative disease, myelodysplasia). Those with good risk disease (first remission acute myeloid leukemia (AML) with myelomonocytic together with bone marrow eosinophilia (M4eos) - inversions in chromosome 16, promyelocytic (M3) AML with translocations in chromosomes (15;17); or translocations in chromosomes (8;21) in first remission are not eligible).

    • Bone marrow failure:

      • Those specifically with idiopathic or secondary moderate, severe or very severe aplastic anemia (idiopathic or secondary) according to the accepted 'Camitta criteria' would be candidates.
      • Those with diseases known to lead to severe marrow failure are eligible as well. These include those with myelofibrosis or Paroxysmal nocturnal hemoglobinuria (PNH).

    • Solid Tumors:

      • Patients must have had a biopsy confirming disease recurrence (metastases) at some point in their history, unless the patient presented with metastatic disease, in which case the initial primary site biopsy is adequate.
  • Patients with renal cell cancer, or melanoma will be eligible for this approach at this time. Patients will have had documented metastatic disease at some time in the past. Patients who are in remission or with residual disease after prior therapy for their metastatic disease are eligible, as there is no accepted cure for these patients with metastatic disease.
  • Breast Cancer- Patients will have had documented metastatic disease at some time in the past. Patients who are in remission or with residual disease after prior therapy for their metastatic disease are eligible. Patient must have failed at least one chemotherapy regimen for their metastatic disease and 1 hormonal agent if they are receptor positive.

Exclusion Criteria:

  • Pregnant or lactating women,
  • Patients with other major medical or psychiatric illnesses which the treating physician feels could seriously compromise tolerance to this protocol, and
  • Leukemia patients in first remission with good risk cytogenetics for leukemia [t(15;17); t(8,22)]

Ander: Donor Apheresis

Donor must be a sibling, half sibling, parent, child or first cousin familial relationship and 3-5/6 Human Leukocyte Antigen matched related to subject. They must not have any medical condition which would make apheresis and G-CSF administration more than a minimal risk, and should have the following:

  1. Adequate cardiac function by history and physical examination
  2. bilirubin and hepatic transaminases < 2.5 x upper limit of normal
  3. normal hematologic parameters Females should have a negative serum pregnancy test.
Procedure: Donor Apheresis
Donor will receive Granulocyte colony-stimulating factor (G-CSF) 10-16 mcg/kg/d subcutaneously (dose will be rounded to the nearest whole vial size and may be divided into twice daily dosing). Granulocyte-macrophage colony-stimulating factor (GM-CSF) 15 mcg/kg/d subcutaneous or similar growth factor for donor mobilization. Donors will receive at least 3-6 doses of daily growth factor until adequate cells are mobilized.

Toxicity
Tijdsspanne: 1 year
Acute graft versus host disease (GVHD) was graded according to the consensus criteria and common terminology criteria (CTC) v3.0 was used for all other toxicities. Recognizing that acute GVHD pathology in the non-ablative and donor lymphocyte infusion (DLI) setting may occur late, we tabulated skin, gut and liver toxicity consistent with acute GVHD (aGVHD) at anytime in the year following the infusion as aGVHD. Toxicities were formally recorded for all patients twice weekly for the first 100 days, at each follow up visit, and as needed intercurrently.
