Utilization of Umbilical Cord Blood-derived Platelet Gel for Treatment of Diabetic Foot Ulcers,a Randomized Double Blind Clinical Trial
Diabetes is a multiorgan disease and considered a major health problem in different societies. One of the complications the pain particularly in the extremities resulting from a process known as diabetic foot ulcer. The diabetic patients are subjected to many complications because of foot ulcers, many of them like as chronic wound disease or pressure ulcers (bed sore). Routinely used medical measures for diabetic foot ulcers are depended to nursing care and take too long until pain relief. Among many tested materials and works for wound healing such as debridement, tissue oxygenation, and skin transplantation, platelet-derived compounds are allocated the pivotal position between investigators to tissue regeneration and shortening the wound healing process. Many of platelet components are procured from platelet rich plasma (PRP) from whole blood donation. Furthermore, it requires to an additional purification step to diminish the volume and facilitate handling in some studies. It means that platelet concentrates (PCs) may be obtained leading to more concentrated platelets in lower volume. Two types of granules in platelet is responsible for storage of many useful and different growth factors: dense or delta and alpha granules. Platelet-derived growth factors have the ability to growth and differentiation of numerous cells. Also, the antibacterial effect of these growth factors has been reported. To better efficacy and comfortable utilization of platelet, it is feasible to form the platelet gel and then apply on wound sites. This study is a double blind randomized controlled trial to evaluate the positive effects of umbilical cord blood-derived platelet gel in 244 patients with diabetic foot ulcers.

Allo-hematopoietic stem cell transplantation(HSCT) is the only way to cure β-thalassemia major at present. To expand donor pool，we developed a haplo-identical HSCT (Hi-HSCT) platform. But in prior Hi-HSCT using high dose post-transplant Cyclophosphamide in patients with leukemia, cytopenia post-transplant often developed, which was considered as a symptom of GVHD. Therefore, the investigators add unrelated umbilical cord blood (UCB) to the Hi-HSCT. It has reported that, as third-party cells, UCB will reduce GVHD.The purpose of this study is to determine whether unrelated UCB following Hi-HSCT can improve outcomes of Hi-HSCT in patients with β-thalassemia major.

T Regulatory Cell for Suppression of Acute Graft-vs-Host-Disease in Recipients of a Non-Myeloablative Umbilical Cord Blood Transplantation for Treatment of Hematological Malignancies
This is a Simon's optimal two-stage phase II trial designed to estimate grade II-IV acute graft-versus-host disease (GVHD) after infusion of T regulatory (nTreg) in a fixed dose ratio to the combined CD3+ cell count of the two graft units in recipients of double UCB transplantation. The nTreg cells (manufactured from a 3rd cord blood unit) are infused on day 0 at least 1 hour after the 2nd unit of the double umbilical cord blood (UCB) transplant. The nTreg cells require an 18 day (±2 days) lead time based on the planned transplant day. The combined CD3+ cell content from the two graft UCB units is enumerated upon thaw (day 0). The patient then receives the number of nTregs cells from the 3rd cord product to achieve a Treg:CD3+ cells ratio of 5:1. The nTreg cell dose depends on the CD3+ cell content of the two graft UCB graft units, but it will not exceed the highest dose level safely tested in the ongoing University of Minnesota phase I Treg dose escalation study MT 2006-01.

Safety of Romiplostim (Nplate®) in Patients Who Have Failed to Achieve Platelet Engraftment Following Umbilical Cord Blood Transplant
This is a single institution, phase I dose escalation study of weekly romiplostim post umbilical cord blood transplantation in patients who fail to achieve platelet engraftment by day +30. Engraftment is defined as a platelet count ≥ 20 x 109/L on 3 consecutive measurements without transfusion for 7 days. Romiplostim is administered at the assigned dose as 6 weekly injections beginning by day +42 post transplant. Up to 4 dose levels (4, 6, 8, and 10 mcg/kg/dose) will be evaluated with the maximum tolerated dose (MTD) of romiplostim determined by using the Continual Reassessment Method (CRM). The goal of this CRM will be to identify 1 of the 4 dose levels which corresponds to the desired maximum toxicity rate of 20% or less.

Treatment of SCID Due to ADA Deficiency With Autologous Transplantation of Cord Blood or Hematopoietic CD 34+ Cells After Addition of a Normal Human ADA cDNA by the EFS-ADA Lentiviral Vector
This is a clinical gene transfer study that aims to verify the safety and efficacy of the use of the EFS-ADA lentiviral vector to introduce the human adenosine deaminase (ADA) gene into the hematopoietic progenitors of patients affected with severe combined immunodeficiency due to ADA deficiency. The EFS-ADA vector expresses the human ADA cDNA under the control of the elongation factor alpha short promoter (EFS). In addition, this protocol will examine the effects of the ADA gene transfer on the immune system of treated patients. Patients with ADA deficiency and ineligible for matched sibling allogeneic bone marrow transplantation are eligible to participate in the study. To increase engraftment and selected advantage or gene-corrected cells, busulfan will be used as a cytoreductive agent. Enzyme replacement (PEG-ADA) will be discontinued 30 days after infusion of gene-corrected cells. CD34+ hematopoietic progenitors will be isolated from the patient bone marrow, peripheral blood or cord blood, exposed to lentiviral vector-mediated gene transfer and re-infused into the patient through a peripheral vein. Clinical, immunological and molecular follow-up studies will assess safety, toxicity, and efficacy of the procedure.

Autologous Cell Therapies for Cerebral Palsy-Chronic (ACT for CP)
The purpose of this study is to compare the safety and effectiveness of two types of stem cells,(either banked cord blood or bone marrow), in children between the ages of 2 to 10 years with CP. 15 children with banked cord blood at CBR and 15 children without banked cord blood will be enrolled into the study. The study involves one baseline/treatment visit and 3 follow-up visits at 6 months, 12 months, and 2 years. Five children in each group will be randomized to a placebo control group at the baseline/treatment visit. Parents will not be told if their child received stem cells or a placebo until the 12 month follow-up visit. At that time parents may elect to have their child receive the stem cell treatment; either bone marrow harvest or umbilical cord blood if banked with CBR. All study visits will be conducted at the UTHealth Medical School and Children's Memorial Hermann Hospital in Houston, Texas. As of 1/21/2014 we have met our enrollment limit for children without banked cord blood undergoing bone marrow harvest for stem cells.

A Phase I/IIa, Open-label, Non-randomized, Study of ASC-101 in Patients With Hematologic Malignancies or Myelodysplastic Syndrome (MDS) Who Are Candidates for Dual-cord Umbilical cord Blood Transplantation (UCBT)
The goal of this clinical research study is to learn if it is safe and feasible to transplant patients with one of two units of cord blood that has been changed in the laboratory before it is given. Only patients with leukemia, lymphoma or myelodysplastic syndrome will be allowed on this study. The secondary goal is to obtain the preliminary efficacy outcome. Researchers also want to learn if using cord blood that has been changed can help to control the disease. One cord blood unit will not be changed before it is administered to you. The cord blood unit that will be altered will be changed to use sugar that is found in small amounts in blood cells. It plays a role in telling transplanted cells where they should go in the body. Adding more sugars to the cord blood cells in the laboratory helps the cord blood cells find their way to the bone marrow faster. This process is called fucosylation. "Conditioning" is the chemo and other medicines and will be given to patients to prepare to receive cord blood transplant cells. This prevents immune system from rejecting the cells. Conditioning will be started before the transplant. ATG is a protein that removes immune cells that cause damage to the body. Clofarabine is designed to interfere with the growth and development of cancer cells. Fludarabine is designed to interfere with the DNA of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's bone marrow cells. Melphalan and busulfan are designed to bind to the DNA of cells, which may cause cancer cells to die. MMF and tacrolimus are designed to block the donor cells from growing and spreading in a way that could cause graft versus host disease (GVHD -- a condition in which transplanted tissue attacks the recipient's body). This may help to prevent GVHD. Rituximab is designed to attach to cancer cells, which may cause them to die. A Phase I study for treatment of patients (N=25) with hematologic malignancies and MDS who are candidates for dual-cord UCBT is ongoing at M.D. Anderson Cancer Center under an Investigator-initiated IND Application, E.J. Shpall, MD, PI. Since August, 2012, Preliminary results indicate that ASC-101 UCBT is well-tolerated and no ASC-101 related untoward adverse events have been observed. To date, the median time to neutrophil engraftment (N=9) is 15 days, and the median time to platelet engraftment (N=9) is 33 days. The trial remains ongoing.

Adoptive Transfer of Cord Blood T Cells to Prevent and Treat CMV, EBV and Adenovirus Infections After Transplantation
In this study, investigators are trying to see if infusion of "m-CTLs" will prevent or treat cytomegalovirus (CMV), Epstein Barr Virus (EBV) and adenovirus (AdV) reactivation or infection after cord blood transplant. Patients with blood cell cancer, other blood disease or a genetic disease may receive a cord blood transplant (UCBT) from an unrelated donor. After receiving a cord blood transplant, they are at risk of infections until a new immune system to fight infections grows from the cord blood cells. In this study, investigators are trying to give special cells from the cord blood called T cells. These cells will try to fight viruses that can cause infection. Investigators will test to see if blood cells from donor that have been grown in a special way, can prevent patients from getting an infection. EBV, AdV and CMV are viruses that can cause serious life-threatening infections in patients who have weak immune systems after transplant. T lymphocytes can kill viral cells but normally there are not enough of them to kill all the virus infected cells after transplant. Some researcher have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person during a viral infection after a bone marrow transplant. Some of these studies have shown a positive therapeutic effect in patients receiving the CTLs (specially trained T cells) after a viral infection in the post-transplant period. In this study we are trying to prevent or treat viral infections by given the CTLs soon after getting the umbilical cord blood transplant. With this study, investigators want to see if they can use a kind of white blood cell called T cells to prevent or treat AdV, EBV and CMV infection. Investigators will grow these T cells from the cord blood before transplant. These cells have been trained to attack adenovirus/EBV/CMV- infected cells and are called multivirus-specific cytotoxic (killer) T-cells or "m-CTL." Investigators would plan to give patients one dose of m-CTL any time from 30 to 364 days after your transplant. They have used T cells made in this way from the blood of donors to prevent infections in patients who are getting a bone marrow or blood stem cell transplant but this will be the first time investigators make them from cord blood.
