TXA127 in Enhancement of Engraftment in Adult Double Cord Blood Transplantation — USBTXA127CBT  

Chronic Lymphocytic Leukemia Clinical Trial

Official title: Phase I Evaluation of the Safety and Efficacy of TXA127 (Angiotensin 1-7) to Enhance Engraftment in Adults Undergoing Double Cord Blood Transplantation

Status Terminated

Clinical Trial Summary

The purpose of this study is to evaluate the effect of TXA127 on neutrophil and platelet counts in adult patients who have undergone a double cord blood transplant. The study will also evaluate the effect of TXA127 on chemotherapy-induced mucositis, an inflammation of the mucous membranes in the digestive tract (mouth to anus) and immune reconstitution which helps patients fight infections. For patients undergoing CBT, both neutrophil and platelet normalization and immune reconstitution can be delayed. TXA127 has shown to be well tolerated by patients and appears to induce a rapid production of neutrophils and platelets in the bloodstream as well as increase the immune system components. It has also been shown to reduce the severity of chemotherapy-induced mucositis.

Clinical Trial Description

Cord blood as a hematopoietic stem cell source has multiple advantages. Cord blood is normally discarded at birth and can easily be collected and stored. Availability of numerous CB banks has resulted in genetically diverse CB units including those from non-Caucasians. Once a suitable CB unit is located, confirmatory typing can be quickly performed and a donor unit can be shipped to the transplant center. Furthermore, because a CB graft results in a lower incidence of graft-versus-host-disease, one or two antigen-mismatched units are acceptable for transplantation. Despite these advantages, CB has a significant drawback which is that the number of hematopoietic stem cells obtained from a unit of CB is significantly lower than from a bone marrow (BM) harvest or peripheral blood stem cell (PBSC) harvest. Both engraftment and immune reconstitution are delayed in patients undergoing CB transplant. TXA127 is pharmaceutically-formulated angiotensin 1-7, a non-hypertensive derivative of angiotensin II (which contains the 8th amino acid conferring receptor binding to blood pressure receptors). TXA127 has multilineage effects on hematopoietic progenitors in vitro and in vivo. The hematopoietic properties demonstrated in preclinical and clinical studies support the investigation of TXA127 to reduce time to neutrophil and platelet engraftment following transfusion of limited number of CD34+ cells. ;
