Plerixafor + G-CSF for Stem Cell Mobilization
(HSCT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new method for collecting stem cells in patients with multiple myeloma or certain types of lymphoma undergoing autologous stem cell transplants. The researchers aim to determine if using G-CSF, a growth factor that increases blood stem cell production, along with selective use of Plerixafor, a drug that moves stem cells from the bone marrow into the blood, can effectively gather enough stem cells while reducing the risk of engraftment syndrome, a condition where new cells cause inflammation. Suitable candidates for this trial have one of the qualifying conditions and are already scheduled for a transplant using their own stem cells. Participants must have previously attempted stem cell mobilization with G-CSF, with or without Plerixafor. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that using Plerixafor with G-CSF is safe for many patients. A large study found that this combination effectively helps the body produce and release stem cells into the blood and is generally well-tolerated. Another study confirmed its safety for patients with certain blood cancers.
However, there is a risk of developing engraftment syndrome, a reaction to the new cells. This trial tests whether starting with G-CSF alone and adding Plerixafor only if needed can still provide enough stem cells while reducing this risk.
Overall, Plerixafor and G-CSF have been used safely in the past, but this trial seeks to improve their use by altering their combination.12345Why are researchers excited about this trial's treatments?
Researchers are excited about Plerixafor + G-CSF because this combination offers a new way to boost stem cell mobilization, which is crucial for successful stem cell transplants. While G-CSF (a growth factor stimulating white blood cell production) is a standard treatment, adding Plerixafor helps release more stem cells into the bloodstream. This means patients who don't initially collect enough stem cells can potentially reach the desired levels faster and more efficiently. This approach could lead to better outcomes for those needing stem cell transplants.
What evidence suggests that this trial's treatments could be effective for stem cell mobilization?
Studies have shown that using both Plerixafor and G-CSF together collects more stem cells than using G-CSF alone. This combination helps more patients reach their stem cell targets, which is crucial for successful transplants. Plerixafor proves especially helpful for those who struggle to collect enough stem cells with just G-CSF. Research also indicates that this method works well for patients with blood cancers like multiple myeloma and lymphoma. However, there is a risk of engraftment syndrome, where the body reacts to the new stem cells. In this trial, all participants will initially receive G-CSF, with Plerixafor added only if necessary, to explore whether this approach can lower the risk of engraftment syndrome while still collecting enough stem cells.16789

Are You a Good Fit for This Trial?
This trial is for adults over 18 with Hodgkin's lymphoma, multiple myeloma, or non-Hodgkin lymphoma. They must have a Karnofsky performance status of at least 60%, good liver function (bilirubin <1.8 and AST/ALT <2.5 times the normal limit), heart function (LVEF ≥40%), and lung capacity (adjusted DLCO ≥45%). Kidney function should be adequate with serum creatinine ≤2.0 mg/dl or clearance >40 ml/min.Inclusion Criteria

Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Mobilization and Collection
Participants receive G-CSF starting on day -4, followed by stem cell collection on day 0. Plerixafor is administered if necessary to achieve target stem cell count.
Transplantation
Autologous stem cell transplantation is performed after successful mobilization and collection of stem cells.
Follow-up
Participants are monitored for safety and effectiveness after transplantation, including engraftment and disease response.
What Are the Treatments Tested in This Trial?
Interventions
- G-CSF
- Plerixafor
Trial Overview
The study tests if using G-CSF alone, with Plerixafor added only when needed, can effectively mobilize stem cells for transplantation in patients while reducing engraftment syndrome risks compared to the standard combined use since FDA approval in 2008.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
All patients will receive G-CSF (peg-filgrastim or filgrastim) on day -4 prior to planned peripheral blood stem cell (PBSC) collection day 0. All patients will proceed with stem cell collection on day 0. If less than 1.7 x 106 CD34+ cells/kg is collected after the first day or the target number of stem cells is not collected after two days, Plerixafor will be administered, and additional collection days will be added until the collection goal is reached.
