Trial summary

With a standard mobilization regimen using G-CSF, approximately 5% of allogeneic donors does not mobilize enough CD34+ cells to reach an optimal dose for transplantation and are therefore called "poor mobilizers". Read more about this study

  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Donor age between 18 years and 75 years
  • Eligibility of the donor for allogeneic PBSC donation according to German Guidelines (Richtlinien Hämotherapie Bundesärztekammer 2005) preceding the application of G-CSF
  • The donor has understood and signed the donor information. Written informed consent has been obtained.
  • Donation of less than 2.0 x 106 CD34 cells/kg recipient body weight after one apheresis following five days of stem-cell mobilization with Lenograstim 7.5 to 10 µg/kg donor body weight

Who cannot join

  • Pain or any discomfort in the left upper square of the abdomen during physical examination immediately prior to study inclusion or any spontaneous complaint about abdominal discomfort without an ultrasound investigation which rules out splenomegaly.

  • Serum creatinine > 80 µmol/l for female donors or > 106 µmol/l for male donors. If serum creatinine is elevated then the estimated creatinine clearance has to be > 50 ml/min. Estimation by the Modification of Diet in Renal Disease equation where predicted GFR(ml/min/1.73m2) = 186 x (Serum Creatinine in mg/dL)-1.154 x (age in years)-0.203 x (0.742 if patient is female) x (1.212 if patient is black) or GFR(ml/min/1.73m2) = 186 x 176 (Serum Creatinine in µmol/l)-1.154 x (age in years)-0.203 x (0.742 if patient is female) x (1.212 if patient is black)
  • Contraindications against a second leukapheresis, such as severe side effects during 1st leukapheresis (intolerable pain, severe circulatory disorder, severe citrate intolerance)
  • Missing written approval by the transplant center that the transplantation of the Plerixafor-mobilized graft is being considered
Show all 11Show fewer
  • Treatment with any known non-marketed drug substance or experimental therapy within 4 weeks prior to enrolment or participation in any other interventional clinical study
  • Any significant concurrent disease, illness, or psychiatric disorder that would compromise donor safety or compliance, interfere with consent, study participation, follow up, or interpretation of study results
  • Female donors of childbearing potential unable or unwilling to use adequate contraception methods for three months after the administration of the study drug. Adequate methods for contraception in female donors are sexual abstinence, the use of condoms by their partners, vasectomy of the partner or hormonal contraception.
  • Male donors unable or unwilling to use adequate contraception methods for one month after the administration of the study drug. Adequate methods for contraception for males are sexual abstinence or the use of condoms.
  • Known intolerance to Plerixafor

About this study

With a standard mobilization regimen using G-CSF, approximately 5% of allogeneic donors does not mobilize enough CD34+ cells to reach an optimal dose for transplantation and are therefore called "poor mobilizers". A generally accepted optimum CD34+ PBSC dose for allogeneic transplantation is > 4.5 x 106/kg body weight of the recipient. The minimum total CD34+ PBSC dose certainly amounts to 2 x 106/kg body weight of the recipient.The objective of this trial is to assess the efficacy of a single dose of Plerixafor as salvage procedure in allogeneic stem cell donors with a poor CD34+ cell yield after the first day of peripheral blood stem cell collection.

Read the detailed description

In this trial the administration of a single dose of Plerixafor 240 µg/kg body weight of the donor SC in the evening at 10 PM after frustraneous stem cell apheresis on day 1 will be provided. The apheresis on day 2 is performed according to standard recommendations.

What is being measured

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

  1. Rate of donation success

    A generally accepted optimum CD34+ PBSC dose for allogeneic transplantation is > 4.5 x 10e6/kg body weight of the recipient. The minimum total CD34+ PBSC dose certainly amounts to 2 x 10e6/kg body weight of the recipient.

    Measured: 1 day

Secondary outcomes (1)
  1. Assessment of donor safety and tolerability based on self-reporting on a questionnaire, clinical findings, and laboratory evaluations; and evaluation of the cellular composition of the apheresis products collected with and without Plerixafor application.

    The composition of apheresis products collected after filgrastim or filgrastim plus Plerixafor will be characterized with respect to:

    • CD34+ cell subsets (differential expression of prominin1/CD133+)33
    • Regulatory T-cells34
    • Dendritic cells
    • Myeloid-derived suppressor cells

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Plerixafor in people with Blood Stem Cell Harvest Failure, run by Technische Universität Dresden at 3 sites in Germany.

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 5 inclusion and 11 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 19 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Germany. 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 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?

Rate of donation success (time frame: 1 day). 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 19 Sep 2016.
