Collection of Bone Marrow From Donors Treated With or Without Filgrastim

Phase 3
Completed
Conditions
No Evidence of Disease
Healthy Stem Cell Donor
Registration Number
NCT01149096
Lead Sponsor
Children's Oncology Group
Brief Summary

This randomized clinical trial is studying the side effects of collection of bone marrow from donors treated with or without filgrastim. Giving colony-stimulating factors, such as filgrastim (G-CSF), to donors helps the stem cells move from the bone marrow to the blood so they can be collected and stored.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate short- and long-term toxicities in bone marrow donors treated with vs without filgrastim before harvest.

II. To compare 10-year mortality and cancer in donors treated with vs without filgrastim.

SECONDARY OBJECTIVES:

I. To correlate the incidence of acute and chronic graft-vs-host disease in the marrow recipients enrolled on COG-ASCT0631 with four parameters assessed in the bone marrow harvests: absolute T-cell numbers, Th1 vs Th2 profile of T-cells, dendritic cell populations, and T-regulatory cell content.

OUTLINE: Donors are randomized to 1 of 2 treatment arms.

ARM I (unstimulated harvest): Donors undergo conventional (i.e., unstimulated) bone marrow harvest on day 0.

ARM II (stimulated harvest): Donors receive filgrastim subcutaneously on days -4 through 0. Donors then undergo bone marrow harvest on day 0.

After completion of study treatment, donors are followed up at 1, 6, and 12 months and then annually for up to 10 years.

Inclusion Criteria
  • Appropriately human leukocyte antigen (HLA)-matched (HLA, A, B, DRB1 identical or antigen mismatched [i.e., 5/6 or 6/6 antigens matched]) sibling of the bone marrow recipient enrolled on COG-ASCT0631

  • Adequate size relative to the recipient (i.e., harvesting the maximum of 20 cc/kg from the donor would result in a bone marrow graft that will provide an adequate cell and volume dose to the recipient, in the opinion of the treating physician)

  • Enrolled on the COG Umbrella Long-Term Follow-Up Study COG-ALTE05N1

  • Not pregnant or nursing

  • No human immunodeficiency virus (HIV) positivity

  • No sickle cell trait or sickle cell anemia/disease

  • Not at an increased risk from bone marrow donation after filgrastim administration due to a pre-existing medical condition, as determined by an independent physician separate from the research team

  • None of the following:

    • Active infection, especially pulmonary
    • Splenomegaly or a history of splenic injury
    • Active or recent pulmonary disease (i.e., pneumonia within the past 4 weeks)
    • A condition that would make the donor unsuitable to donate, as determined by an independent physician separate from the research team
  • No autoimmune disease

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Short-term Adverse Events in G-CSF (Filgrastim) Stimulated Bone Marrow (G-BM) DonorsUp to 1 year after donation

The Kaplan-Meier method will be used to estimate the cumulative incidence of short term adverse events defined by having any of the following events: 1) death due to a cause that is unknown or possibly related to G-CSF, 2) development of a malignancy, 3) development of a splenic rupture, or 4) development of a severe acute lung injury possibly related to GCSF therapy.

Percentage of Participants Who Experienced Death in G-CSF Stimulated-bone Marrow (G-BM) DonorsUp to 1 year after donation

The Kaplan-Meier method will be used to estimate the cumulative incidence of death event in G-BM donors only.

Percentage of Participants With Grade 1 or 2 ToxicitiesUp to 1 year after donation

Estimate the percentage of patients having non-fatal complications of CTCAE Grades 1 or 2 in standard BM and G-CSF stimulated-bone marrow (G-BM) donors.

Percentage of Participants With Grade 3 or 4 ToxicitiesUp to 1 year after donation

Estimate the percentage of patients having non-fatal complications of Grade 3 other than pain (consider Grade 4 for pain only), or any of Grade 4 in standard BM and G-CSF stimulated-bone marrow (G-BM) donors. Modified Toxicity Criteria and Pain Assessment was used with higher grades corresponding to more severe AEs.

10-year Overall Cancer IncidenceUp to 10 years post bone marrow harvest

The Kaplan-Meier method will be used to estimate overall cancer free probabilities in standard BM and G-BM donors.

10-year Mortality Rate in Marrow DonorsUp to 10 years post bone marrow harvest

The Kaplan-Meier method will be used to estimate overall survival probabilities in standard BM and G-BM donors.

10-year Hematologic Cancer RateUp to 10 years post bone marrow harvest

The Kaplan-Meier method will be used to estimate hematologic cancer probabilities in standard BM and G-BM donors.

Secondary Outcome Measures
NameTimeMethod
Absolute T Cell NumbersUp to 1 year after donation

Median and interquartile range of the outcome measure in standard BM and G-BM donors.

Th1 vs. Th2 Profile of T CellsUp to 1 year after donation

Proportion of donors with Th1-T cell profile in standard BM and G-BM donors.

T Regulatory Cell ContentUp to 1 year after donation

Median and interquartile range of the outcome measure in standard BM and G-BM donors.

Dendritic Cell (DC) PopulationsUp to 1 year after donation

Median and interquartile range of the outcome measure in standard BM and G-BM donors.
