A Randomized Study of Peripheral Blood Progenitor Cell Priming Comparing a Combination of r-metHuSCF and Filgrastim or Chemotherapy and Filgrastim on Mobilization and Engraftment in Patients With Relapsed or Refractory Lymphomas

Autologous stem cell transplantation is used to support high dose chemotherapy in
haematological malignancies.1-2 Peripheral blood progenitor cells (PBPC) have replaced bone
marrow cells as the preferred source for transplantation due to faster blood cell
recovery.3-4 One variable of major impact for posttransplant care is the number of PBPC
harvested.5-8 Therefore, several clinical studies have aimed to identify priming regimens
that improve progenitor and stem cell mobilizations and collections without increased
toxicity. Frequently, Filgrastim (r-met HuG-CSF) is administrated alone; however, Filgrastim
combined with chemotherapy has proven more effective in context of CD34+ cell numbers
harvested9-11 and this combination is considered the gold standard for priming and stem cell
mobilization in relapsed malignant lymphoma.

Stem cell factor (SCF) is a glycoprotein growth factor that acts on haematopoietic blood
cell progenitors.12 Whereas SCF alone exerts little colony-stimulating activity on normal
human bone marrow cells in vitro, combination of SCF with other recombinant haematopoietic
cytokines results in a synergistic increase in numbers of colonies.13 In vivo, the addition
of SCF to G-CSF (Filgrastim) synergistically increases PBPC mobilization compared to
Filgrastim alone.14-17 Several clinical trials have reported the ability of the combination
of SCF with Filgrastim to mobilize PBPC in patients with lymphoma, multiple myeloma, breast
and ovarian cancers even in heavily pretreated patients.18-26 Priming using chemotherapy is
toxic and costly11 and new priming procedures need to be established, which is the
background for this randomized pilot study. The hypothesis is that elimination of
chemotherapy from the priming regimen may decrease the overall toxicity and the ability to
collect a sufficient autograft which, however, may be circumvented by adding r-metHuSCF
(Ancestim) to the priming regimen. The aim of this randomized phase II trial was to evaluate
safety, toxicity and efficacy of growth factors in lymphoma patients considered candidates
for high dose chemotherapy.
