Mobilization of Stem Cells With AMD3100 (Plerixafor) in Multiple Myeloma Patients

10 februari 2014 bijgewerkt door: Genzyme, a Sanofi Company

A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Comparative Trial of AMD3100 Plus G-CSF Versus G-CSF Plus Placebo to Mobilize and Collect ≥ 6*10^6 CD34+ Cells/kg in Multiple Myeloma Patients for Autologous Transplantation

The purpose of this study is to determine whether the combination of AMD3100 (plerixafor) and granulocyte colony-stimulating factor (G-CSF, generic name of filgrastim) is better than G-CSF alone to mobilize and collect the optimal number of stem cells in multiple myeloma patients for autologous transplantation.

Studie Overzicht

Gedetailleerde beschrijving

A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Currently filgrastim (G-CSF), a colony stimulating factor, is used to cause the growth and mobilization of stem cells from bone marrow to peripheral blood, which can then be collected from the peripheral blood by a process called apheresis. Plerixafor aids in the release of the stem cells from the bone marrow into the peripheral blood, possibly allowing for a more rapid collection of a larger number of stem cells from the peripheral blood. Larger stem cell doses for transplantation correlate to faster recovery times after high dose chemotherapy followed with stem cell transplantation. This study is intended to determine whether the combination of plerixafor with filgrastim (G-CSF)is better than filgrastim (G-CSF) alone in helping multiple myeloma patients collect at least 6 million stem cells in two or less apheresis sessions.

Experimenteel: G-CSF plus plerixafor
Participants underwent mobilization with granulocyte colony-stimulating factor (G-CSF) (10 µg/kg/day) for 4 days, administered by subcutaneous (SC) injection. On the evening of Day 4, participants received plerixafor (240 µg/kg), administered by SC injection. On Day 5, participants received a morning dose of G-CSF (10 µg/kg) and underwent apheresis approx. 10 to 11 hours after the dose of plerixafor (within 60 minutes of G-CSF administration). Participants continued to receive an evening dose of plerixafor followed by a morning dose of G-CSF and apheresis for up to 4 aphereses or until ≥ 6*10^6 CD34+ cells/kg were collected. Participants who participated in the rescue procedure underwent an additional daily treatment with plerixafor (240 µg/kg) and apheresis for up to 4 days.

Maatregel Beschrijving
Tijdsspanne
Aantal deelnemers met bijwerkingen
Tijdsspanne: tot dag 38
Aantal deelnemers met tijdens de behandeling optredende bijwerkingen (AE's). Het tijdsbestek voor tijdens de behandeling optredende bijwerkingen wordt gedefinieerd als dag 1 (start van G-CSF-mobilisatie) tot de dag vóór aanvang van de chemotherapie (ongeveer 38 dagen later).

Engraftment was defined as PMN counts ≥ 0.5*10^9/L for 3 consecutive days or ≥ 1.0*10^9/L for 1 day.

The Kaplan Meier estimate of median number of days to PLT engraftment (number of days at which 50% of participants have experienced the event, accounting for censored values) was a secondary efficacy endpoint. Engraftment was defined as ≥ 20*10^9/L without transfusion for the preceding 7 days. Time to engraftment corresponded to the first day that the criteria were met and was evaluated up to 12 months post transplant.
