Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 6 months to 20 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Subject, parent, or legal guardian provided written informed consent.
  • Subjects must be >6 months and <21 years of age.
  • Subjects must have one or two available 4, 5, or 6/6 antigen matching unrelated UCB unit(s) that will deliver a cell dose between 3.0-5.0 x 107cells/kg.
  • These units must be HLA-matched minimally at 4 of 6 HLA-A and B (at intermediate resolution by molecular typing) and DRB1 (at high resolution by molecular typing) loci with the subject.
  • If two CB units will be used, the units must be HLA-matched at 3 of 6 HLA- A, B, and DRB1 loci with each other (using same resolution of molecular typing as indicated above).
  • For a single unit transplant, a minimum of 3 x 107cells/kg will be required.
Show all 19Show fewer
  • For a double unit transplant, HLA-matched units must be available such that together both units deliver a combined pre-cryopreserved nucleated cell dose of at least 4.0 x 107 cells/kg with 1 unit of at least 2.5 x 107 cells/kg and the other at least 1.5 x 107 cells/kg.
  • Subjects must have histologically confirmed diagnosis of a hematologic malignancy or a laboratory confirmed inherited metabolic disease.
  • Subjects who have had a prior autologous or allogeneic transplant are allowed to participate provided it has been >1 year since the transplant was completed.
  • Subjects must not have active CNS disease at the time of study enrollment.
  • Subjects must have a life expectancy of >4 months.
  • Female subjects capable of reproduction (defined as a subject who has started menses) must agree to the following:
  • Use of an effective oral or IM contraceptive method during the course of the study and 2 months following the last administration of study drug.
  • Female subjects capable of reproduction must have a negative pregnancy test result within 3 days prior to first study drug dose.
  • Subjects must have adequate function of other organ systems as measured by:
  • Creatinine <2.0 mg/dL and creatinine clearance >50 mL/min.
  • Hepatic transaminases (ALT/AST) <4 x ULN, bilirubin <2.0 mg/dL.
  • Adequate cardiac function by echocardiogram or MUGA scan (ejection fraction or shortening fraction >80% of normal value for age).
  • Pulmonary function tests demonstrating FVC and FEV1 of >60% of predicted. DLCO should be used for subjects >10 years old. Crying vital capacity of >60% may be substituted for subjects unable to complete PFTs.

Who cannot join

  • Subjects with an uncontrolled infection at the time of cytoreduction.
  • Subjects who are pregnant or breast feeding.
  • Subjects who are known to be seropositive for HIV or HTLV-1.
  • Subjects who have had an autologous or allogeneic transplant <1 year from the anticipated administration of the first dose of study drug.
  • Subjects who have received treatment with an investigational agent within 30 days of anticipated administration of the first dose of study drug.
  • 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 must not have any co-morbid condition which, in the view of the Principal Investigators, renders the subject at too high a risk from treatment complications and regimen-related morbidity/mortality.

About this study

Engraftment failure is a major obstacle to the success of cord blood transplantation in children with malignancies and inherited metabolic disorders, despite the fact that they receive relatively high doses of nucleated cells from UCB. TXA127 is pharmaceutically formulated Angiotensin 1-7 [A(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. Preclinical data show that TXA127 is a novel stimulator of early multilineage hematopoietic progenitors, increases engraftment of committed hematopoietic progenitors, and induces more rapid production of platelets and neutrophils in the peripheral circulation, especially in limited cell number transplants. Treatment with TXA127 following UCBT is expected to increase the numbers of hematopoietic progenitors and accelerate engraftment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TXA127 in people with Cord Blood Transplant and Hematologic Malignancy, run by Tarix Pharmaceuticals at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 31 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of TXA127 in subjects undergoing cord blood transplantation (time frame: Through Day 100 post transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2016.
