Study of ASC-101 in Patients With Hematologic Malignancies Who Receive Dual-cord Umbilical Cord Blood Transplantation

• Status: Unknown status
• Trial end date: 1969-12-31

Summary

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.
