Study Details

Study Description

Brief Summary

Neutropenia, a condition characterized by an abnormally low number of infection-fighting white blood cells called neutrophils, commonly develops in people who have undergone chemotherapy or hematopoietic stem cell (HSC) transplantation. The severely reduced immunity of those with neutropenia can put them at risk of entry of life-threatening infections, making the implementation of treatments that increase white blood cell numbers important. Several studies have shown that the transfusion of donor granulocytes, a type of white blood cell that includes neutrophils, is effective in promoting the recovery of adequate numbers of granulocytes. However, granulocyte transfusions can cause side effects, and it is not known whether the success of the therapy outweighs the health risks of the side effects. This study will evaluate the safety and effectiveness of granulocyte transfusions in treating people with a bacterial or fungal infection during neutropenia.

Condition or Disease Intervention/Treatment Phase
  • Drug: Standard antimicrobial therapy
  • Biological: Granulocyte transfusions
  • Drug: G-CSF/dexamethasone
  • Device: Apheresis machine
Phase 3

Detailed Description

Thousands of people each year are hospitalized for neutropenia, which continues to cause substantial morbidity and mortality for those affected. Neutropenia is primarily caused by chemotherapy and various other cancer treatments, such as radiation therapy, biotherapy, and HSC transplantation. Signs and symptoms of neutropenia may include high fever, chills, sore throat, and diarrhea. In neutropenia, the number of neutrophils, a type of granulocyte, is greatly reduced, weakening the body's immune system and increasing the risk of infection. Therefore, a method to provide adequate numbers of functional granulocytes to people with neutropenia could be of greatest benefit for recovery. Administration of a combination of two drugs, granulocyte colony-stimulating factor (G-CSF) and dexamethasone, has been show to stimulate the body to produce a large number of granulocytes. Granulocyte transfusions obtained from donors who have received these two drugs may help people with low white blood cell counts fight infections until their own white blood cell counts recover. However, it is not clear whether the benefits of granulocyte transfusions outweigh the risks of side effects. This study will compare the safety and effectiveness of granulocyte transfusions with standard antimicrobial therapy versus the safety and effectiveness of standard antimicrobial therapy alone in increasing granulocyte numbers and in improving survival rates in people with bacterial or fungal infection during neutropenia.

Participation in the research portion of this study will last about 3 months. All participants who were not previously receiving treatment with standard antimicrobial therapy will begin therapy immediately upon study entry. Participants will then be assigned randomly to receive either granulocyte transfusion plus continued antimicrobial therapy or continued antimicrobial therapy alone. All participants will be monitored for a maximum of 42 days, during which they will provide information on medical history and ongoing status of antimicrobial therapy. Daily blood samples to measure white blood cell count will be obtained from participants until samples show that participants are making their own granulocytes. Samples will then be collected weekly until Day 42. There may be additional blood draws depending on the type of infection present in participants.

Granulocyte transfusions will be given daily during the 42-day treatment period, depending on granulocyte donor availability. Blood counts will be checked immediately before and after each transfusion to measure granulocyte levels. Transfusions will be stopped if participants start making their own granulocytes, experience serious side effects, or show a reduction in infection. At Month 3 after study entry, follow-up information will be collected about all participants' health status through reviewing their medical records and contacting their physicians.

Participation for granulocyte donors will last 1 week from the time of donation. Community donors may provide more than one granulocyte donation, but no more than one donation every 3 days. Frequency of donation from a family member will be according to local blood bank criteria with approval from a blood bank physician. Both community donors and family donors are limited to eight donations each year. Twelve hours before each donation, participants will be injected with Neupogen, which contains G-CSF, and they will take one dose of dexamethasone by mouth. Participants will then undergo a blood draw, followed by a procedure using an apheresis machine for granulocyte collection. The procedure will last 3 to 4 hours and will involve the drawing of blood from each arm, the separation of granulocytes from the red blood cells and plasma in the machine, and the return of the red blood cells and plasma to the participants.

Arms and Interventions

Arm Intervention/Treatment
Experimental: 1

Participants will receive granulocyte transfusions in addition to standard antimicrobial therapy

Drug: Standard antimicrobial therapy
Antimicrobial therapy is broadly defined as therapy within the standard of care for a particular infection and should be consistent within a given institution. Participants will undergo the recommended therapy for specific infections for 42 days.

Biological: Granulocyte transfusions
Participants will receive one granulocyte transfusion per day until one of the following occurs: recovery from neutropenia, life-threatening toxicity, resolution or improvement of infection, or Day 42 after treatment. Granulocyte content of each transfusion is targeted to be at least 4 x 10^10 per collection (or proportionately less for participants less than 30 kg in weight).

Active Comparator: 2

Participants will receive standard antimicrobial therapy alone

Drug: Standard antimicrobial therapy
Antimicrobial therapy is broadly defined as therapy within the standard of care for a particular infection and should be consistent within a given institution. Participants will undergo the recommended therapy for specific infections for 42 days.

Other: 3

Participants will donate granulocytes after receiving a combination of two drugs, G-CSF and dexamethasone

Drug: G-CSF/dexamethasone
Twelve hours before each donation, participants will be injected with G-CSF and will take one dose of dexamethasone by mouth.
Other Names:
  • Neupogen
  • Device: Apheresis machine
    Participants will undergo a procedure using an apheresis machine for granulocyte collection. The procedure will last 3 to 4 hours and will involve the drawing of blood from each arm, the separation of granulocytes from the red cells and plasma in the machine, and the return of the red cells and plasma to the participants.

    Description
    Time Frame Measured at Week 1 after G-CSF administration

    Outcome Measure Data

    Analysis Population Description
    237 subjects consented to G-CSF and dexamethasone administration prior to granulocyte donation.
    Arm/Group Title Granulocyte Donors
    Arm/Group Description Participants will donate granulocytes after receiving a combination of two drugs, G-CSF and dexamethasone G-CSF/dexamethasone: Twelve hours before each donation, participants will be injected with G-CSF and will take one dose of dexamethasone by mouth. Apheresis machine: Participants will undergo a procedure using an apheresis machine for granulocyte collection. The procedure will last 3 to 4 hours and will involve the drawing of blood from each arm, the separation of granulocytes from the red cells and plasma in the machine, and the return of the red cells and plasma to the participants.

    Adverse Events

    Time Frame Serious adverse events were reported up to 42 days after randomization.
    Adverse Event Reporting Description Serious adverse events and other adverse events (i.e. granulocyte transfusion related events) data were collected. The number of participants at risk for other adverse events corresponds to the number of participants who received granulocyte transfusions (6 control arm subjects and 51 granulocyte arm subjects).
    Arm/Group Title Control Arm Granulocyte Arm
    Arm/Group Description Received antimicrobial therapy alone. Received G-CSF/dexamethasone-mobilized granulocyte transfusions in addition to antimicrobial therapy.
