Cord Blood Expansion on Mesenchymal Stem Cells

Completed · Phase 1

Conditions studied: Myelodysplastic Syndrome, Leukemia

In brief

The goal of this clinical research study is to learn if combining cord blood units will be safe and result in the cells "taking" faster in recipients. The cord blood units will have their cell number increased in the lab using cells from a family member or they will be collected from an unrelated healthy donor.

Who can join

Age: 1 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must have one of the following hematologic malignancies: Acute Myelogenous Leukemia (AML), induction failure, high-risk for relapse first remission (with intermediate-risk or high-risk cytogenetics, flt3 mutation positive and/or evidence of minimal residual disease by flow cytometry), secondary leukemia from prior chemotherapy and/or arising from MDS, Langerhan's cell histiocytosis, any disease beyond first remission; or,
• Myelodysplastic Syndrome (MDS): Primary or therapy related; or,
• Acute Lymphoblastic Leukemia (ALL): induction failure, primary refractory to treatment (do not achieve complete remission after first course of therapy) or are beyond first remission including second or greater remission or active disease.
• #3, continued: Patients in first remission are eligible if they are considered high risk, defined as any of the following detected at any time: with translocations 9;22 or 4;11, hypodiploidy, complex karyotype, secondary leukemia developing after cytotoxic drug exposure, and/or evidence of minimal residual disease, or acute biphenotypic leukemia, or double hit non-Hodgkin's lymphoma; or,
• Non-Hodgkin's Lymphoma (NHL) in second or third complete remission, or relapse (including relapse post autologous hematopoietic stem cell transplant). Double hit lymphomas in first remission or more advanced disease; or,
• Small Lymphocytic Lymphoma (SLL), or Chronic Lymphocytic Leukemia (CLL) with progressive disease following standard therapy; or,
• CML second chronic phase or accelerated phase; or,
• Hodgkin's Disease (HD): Induction failures, second or third complete remission, or relapse (including relapse post autologous hematopoietic stem cell transplant); or,
• Multiple Myeloma: stage II or III, symptomatic, secretory Multiple Myeloma requiring treatment.
• Age greater than or equal to 1 year but less than or equal to 55 years (Myeloablative Regimen 4). Eligibility for pediatric patients will be determined in conjunction with an MD Anderson Cancer Center (MDACC) pediatrician. Patients >55 but < 65 years who have a Performance Status of 0 or 1 and no comorbidities may receive the myeloablative regimen 4 at the discretion of the investigator(s).
• Age greater than 55 years and less than or equal to 80 years (Nonmyeloablative Regimen 2)
• Age greater than or equal to 1 but less than or equal to 80 years old that in the opinion of the investigator(s) would preclude myeloablative therapy and who cannot receive Total Body Irradiation (TBI) may receive reduced intensity regimen 3.
• Performance score of at least 60% by Karnofsky or PS less than 3 (ECOG) (age greater than or equal to 12 years), or Lansky Play-Performance Scale of at least 60% or greater (age <12 years)
• Left ventricular ejection fraction of at least 40% (Myeloablative Regimen 4, Reduced Intensity Regimen 3) or 30% (Nonmyeloablative Regimen 2)
• Pulmonary function test demonstrating a diffusion capacity of least 50% predicted (Myeloablative Regimen 4, Reduced Intensity Regimen 3) or at least 40% predicted (Nonmyeloablative Regimen 2). For children < 7 years of age who are unable to perform pulmonary function test (PFT), oxygen saturation > 92% on room air by pulse oximetry.
• Creatinine < 1.6 mg/dL (Myeloablative Regimen 4, Reduced Intensity Regimen 3) or < 3.0 mg/dL (Nonmyeloablative Regimen 2).
• Serum glutamate pyruvate transaminase (SGPT)/bilirubin < / = to 2.0 x normal (Myeloablative Regimen 4, Reduced Intensity Regimen 3) or < / = 4.0 x normal (Nonmyeloablative Regimen 2)
• Negative Beta HCG test in a woman with child bearing potential defined as not post-menopausal for 12 months or no previous surgical sterilization and willing to use an effective contraceptive measure while on study.
• Unrelated Cord Blood will be used as a source of hematopoietic support if a 5 or 6/6 related or 6/6 unrelated bone marrow donor is not available, or if the tempo of a patient's disease dictates it is not in the patient's best interest to wait for an unrelated marrow donor to be procured.
• Patients must have two Cord Blood units available which are matched with the patient at 4, 5, or 6/6 HLA class I (serological) and II (molecular) antigens. Each cord must contain at least 10 million total nucleated cells/Kg recipient body weight (pre-thaw)
• Patients must have a family member who is matched at 2, 3, or 4 HLA antigens typed as described above and willing to donate 80-100 ml or bone marrow for MSC generation or the Angioblast Mesenchymal Precursor Cells will be used for the cord blood co-cultures. Patients that are high risk for relapse are eligible to use the Angioblast "off-the-shelf" Mesenchymal Precursor Cells.
• Have identified a back-up cell source in case of engraftment failure. The source can be autologous, related, or unrelated.

You may not qualify if…

• HIV positive
• Positive beta HCG in female of child-bearing potential defined as not post-menopausal for 12 months or no previous surgical sterilization or breast-feeding.
• Uncontrolled serious medical condition such as persistent septicemia despite adequate antibiotic therapy, decompensated congestive heart failure despite cardiac medications or pulmonary insufficiency requiring intubation. (excluding primary disease for which CB transplantation is proposed), or psychiatric condition that would limit informed consent.
• Active central nervous system (CNS) disease in patient with history of CNS malignancy.
• Availability of appropriate, willing, HLA-matched related marrow donor.
