Mozobil (plerixafor) to mobilize stem cells for autologous transplant
Official title: A Prospective Trial Evaluating Plerixafor-based Mobilization and Risk of Engraftment Syndrome After Autologous Hematopoietic Stem Cell Transplantation
Run by Thomas Jefferson University · NCT07188090 · Data updated 2026-11-12
This trial will test whether starting with G‑CSF and giving Plerixafor only when needed can collect enough stem cells for adults with multiple myeloma or lymphoma undergoing autologous transplant while possibly lowering engraftment syndrome.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with multiple myeloma, Hodgkin lymphoma, or non‑Hodgkin lymphoma planned for autologous HSCT who have Karnofsky ≥60% and meet the study's organ‑function and institutional HSCT criteria.
✕Probably not a fit
Patients who are known poor mobilizers, who require immediate or routine upfront Plerixafor, or who do not meet performance status or organ‑function eligibility are unlikely to benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, single‑arm, open‑label trial using G‑CSF as the primary mobilizing agent with risk‑adapted use of Plerixafor. Patients start G‑CSF (peg‑filgrastim or filgrastim) before planned collection and undergo apheresis on day 0 with a target of about 3 x 10^6 CD34+ cells/kg. Plerixafor is given only if collection yields are <1.7 x 10^6 CD34+ cells/kg after the first day or if targets are not met after two days; pre‑collection peripheral CD34+ counts are measured but not used to trigger Plerixafor. The study measures incidence of engraftment syndrome and stem cell collection success compared with historical rates.
Why it matters
Potential benefit: If successful, this approach could reduce engraftment syndrome while still achieving adequate stem cell collection, making mobilization safer and simpler for patients.
How similar studies have gone: Combining G‑CSF and plerixafor is established to improve stem cell yield, but prospective data on a risk‑adapted strategy specifically aimed at reducing engraftment syndrome are limited.
