TXA127 in Enhancement of Engraftment in Adult Double Cord Blood Transplantation (USBTXA127CBT)
2020년 12월 7일 업데이트: Tarix Pharmaceuticals
Phase I Evaluation of the Safety and Efficacy of TXA127 (Angiotensin 1-7) to Enhance Engraftment in Adults Undergoing Double Cord Blood Transplantation
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.

상세 설명
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.

Inclusion Criteria:
- Subjects with Acute Myelogenous Leukemia (AML) past first remission, in first or subsequent relapse, induction failure, or in first remission with high-risk for relapse (with high-risk cytogenetics or presence of flt3 mutation or secondary leukemia from prior chemotherapy)
- Myelodysplastic Syndrome or Myelofibrosis of intermediate or high-risk
- Acute Lymphoblastic Leukemia (ALL): Induction failure, fist complete remission with Philadelphia chromosome or translocation (4:11), hypodiploidy and or evidence of minimal residual disease by flow cytometry, second or third complete remission or second relapse
- Chronic Myelocytic leukemia (CML): Second chronic phase or accelerated phase
- Non-Hodgkin's Lymphoma (NHL): Induction failures, second or third complete remission or relapse
- Hodgkin's Lymphoma (HL): Induction failures, second or third complete remission or relapse
- Chronic Lymphocytic leukemia (CLL): Progressive disease following standard therapy
- Other hematologic malignancies which meet investigational site standards for cord blood transplant
- Subjects must be at least 18 years of age
- Subjects must have ECOG status of ≤ 2
- Subjects with bone marrow blasts ≤ 10%
- Subjects must have adequate major organ function
- Male and Female Subjects capable of reproduction must agree to use contraceptive methods during the course of the study and for 2 months following the last administration of study drug
- Cord blood requirements: a) Unrelated CB will be used as a source of hematopoietic support if a 7/8 or 8/8 related or 8/8 unrelated bone marrow donor is not available, or if the tempo of the subject's disease dictates it is not in the subject's best interest to wait for an unrelated marrow donor to be procured. b) Subjects must have two CB units available which are matched with the subject at 4/6, 5/6, or 6/6 HLA class I (serological) and II (molecular) antigens. Each unit must contain at least 1 x 10^7 total nucleated cells/kg recipient body weight (pre-thaw).
Exclusion Criteria:
- Subjects who received antineoplastic treatment including chemotherapy, immunotherapy and radiation therapy ≤ 2 weeks prior to Screening Period
- Subjects who underwent prior total body irradiation
- Subjects who received prior allogeneic hematopoietic cell transplants
- Subjects seropositive for HIV, Hepatitis B or Hepatitis C
- Female subjects who are pregnant or breastfeeding
- Subjects who have received an investigational drug within 30 days of projected first administration of study drug (Day 0)
- Subjects with current alcohol use, illicit drug use, or any other condition (e.g., psychiatric disorder) that, in the opinion of the Investigator, may interfere with the subject's ability to comply with the study requirements or visit schedule
- Subjects with known hypersensitivity to TXA127
- Subjects with uncontrolled medical or psychiatric condition which would limit informed consent
- Subjects with a willing and appropriate HLA-matched related marrow donor
