About this study

Official title: Phase I Double-Blinded Comparison Study Using TXA127 and/or Neupogen to Increase Peripheral Blood Stem Cell (CD34+) Counts

This is a Phase I Study to be conducted in 18 healthy volunteers. Each will receive daily injections for 5 days of TXA127 alone, or Neupogen alone, or TXA127 plus Neupogen together.

The aim of the study is to determine the safety of the TXA127 alone and in combination with Neupogen, and to determine whether the use of TXA127 alone or in combination with Neupogen enhances peripheral blood stem cell (CD34+)mobilization.

Read the detailed description

In this double-blinded comparison study, healthy volunteers will be randomized to one of 3 treatment groups: (Group A) TXA127 at 300 mcg/kg once a day for 5 days or (Group B) Neupogen 10 mcg/kg once a day for 5 days or (Group C) both together once a day for 5 days, these treatments administered by subcutaneous injection, to increase peripheral blood stem cell (CD34+) concentrations in healthy volunteers.

A minimum of 18 healthy male and female volunteer Subjects (6 in each treatment group) who meet all inclusion and none of the exclusion criteria will be enrolled in this study. Subjects will be recruited from the study center's existing database of healthy volunteers and/or by advertising. A sufficient number of alternate volunteers will be screened and checked-in on Day 0 to ensure 6 eligible healthy volunteers are enrolled on Day 1 in each treatment group. Subjects will remain housed in teh Unit during the conduct of this study.

Safety: Predose blood samples will be collected immediately prior to receiving the study medication(s), as well as at 4 hours, 8 hours, 12 hours and 16 hours post-dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants with adverse events as a measure of safety and tolerability

    In this phase I study the primary safety variables being assessd include laboratory variables (chemistry, hematology, coagulation system parameters, and urinalysis) and regular vital signs, injection site inspection, and physical exams as indicated.

    Measured: Assessed daily during dosing (Days 1 - 5) and at the two follow up visits (Day 7 and Day 12).

Secondary outcomes (1)
  1. Preliminary effectiveness as assessed by changes in the concentration of peripheral blood stem cells (CD34+) and other hematologic parameters.

    Parameters being assessed for preliminary effectiveness in this phase I study include routine chemistry and hematology parameters and flow-cytometric evaluation of blood samples for CD34, CD3, CD4, CD8 and CD19 concentrations at 4, 8, 12 and 16 hours post-dose

    Measured: Daily assessment during dosing (Days 1 - 5) and at the two follow up visits (Days 7 and 12)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TXA127 and Neupogen (filgrastim) in people with Miscellaneous Peripheral Blood Cell Abnormalities, 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 6 inclusion and 16 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: finished, 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of participants with adverse events as a measure of safety and tolerability (time frame: Assessed daily during dosing (Days 1 - 5) and at the two follow up visits (Day 7 and Day 12).). 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.
