About this study

Official title: A Phase I/II Study Evaluating the Safety and Efficacy of Intravenous POL6326 for the Mobilization and Transplantation of HLA-Matched Sibling Donor Hematopoietic Stem Cells in Patients With Advanced Hematological Malignancies

Determine the safety and tolerability of POL6326 when used as a single mobilization agent.

Read the detailed description

Current protocols use G-CSF to mobilize hematopoietic progenitor cells from matched sibling donors. This process requires from four to six days of G-CSF injection and is associated with significant morbidity, most notably bone pain. POL6326 is associated with few side effects and collection of cells occurs on the same day as POL6326 administration.

This study will evaluate the safety and efficacy of this novel agent for hematopoietic progenitor cell mobilization and allogeneic transplantation based on the following hypotheses:

  1. Donors mobilized with intravenous POL6326 will require fewer collections than have previously been seen for donors mobilized with subcutaneous plerixafor.
  2. Healthy HLA-matched donors receiving one or two infusions of POL6326 will mobilize sufficient CD34+ cells (at least 2.0 x 106 CD34+ cells/kg recipient weights) following leukapheresis to support a hematopoietic cell transplant.
  3. IV POL6326 will result in more rapid kinetics and a higher maximum (peak) of human CD34+ stem cells mobilized from human normal allogeneic donors compared to previous donors who were mobilized with plerixafor.
  4. The hematopoietic cells mobilized by IV POL6326 will be functional and will result in prompt and durable hematopoietic engraftment following transplantation into HLA-identical siblings with advanced hematological malignancies using various non-myeloablative and myeloablative conditioning regimens and regimens for routine GVHD prophylaxis.

What is being measured

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

  1. Phase I Study - safety and tolerability of POL6326 as a mobilization agent.

    Measured: 30 days

  2. Phase II Study - determine the number of allogeneic donors who require a second leukapheresis

    Determine the number of allogeneic donors which collect >= 2 mill CD34+ cells with one or two leukapheresis procedures treated with IV POL6326. Comparison with historic group of donors who were mobilized with 240 µg/kg SC plerixafor.

    Measured: 2 days

Secondary outcomes (5)
  1. Phase I Study - define maximum tolerated dose of POL6326

    Measured: 30 days

  2. Phase II Study - the proportion of HLA-identical sibling donors who experience grade 3-4 infusional toxicity and the proportion who are safely mobilized

    To estimate the proportion of HLA-identical sibling donors who experience grade 3-4 infusional toxicity and the proportion from whom > 2 mill CD34+ cells/kg recipient weight are safely mobilized following one or two leukapheresis procedures

    Measured: 30 days

  3. Phase II Study - pharmacokinetics and pharmacodynamics of IV POL6326

    Stem cell and T-cell phenotyping

    Measured: Day 1-3

  4. Phase II Study - rate of acute GVHD and chronic GVHD in patients who receive IV POL6326 mobilized peripheral blood stem cells.

    Acute GVHD - Day 100 (+/- 7 days) Chronic GVHD - Day 365 (+/- 14 days)

    Measured: Day 100 (+/- 7 days) or Day 365 (+/-14 days)

  5. Phase II Study - kinetics of neutrophil and platelet engraftment in recipients of POL6326 mobilized peripheral blood stem cells.

    Measured: Day 365 (+/- 14 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing POL6326, Leukapheresis and PBSC Transplant in people with Acute Myeloid Leukemia in Remission and Adult Acute Lymphoblastic Leukemia in Remission, run by Polyphor Ltd. at 2 sites 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?

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 26 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 combined 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.

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 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?

Phase I Study - safety and tolerability of POL6326 as a mobilization agent. (time frame: 30 days). The study lists 2 primary outcomes in all. 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 26 Feb 2016.
