E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate efficacy of plerixafor in patients with multiple myeloma in comparison to G-CSF alone for stem cell mobilization, as measured by stem cell harvest results sufficient for tandem-transplantation in only one collection. |
|
E.2.2 | Secondary objectives of the trial |
To assess safety and tolerability of plerixafor in patients with multiple myeloma To assess effect of plerixafor on collection efficiency (CE1 and CE2) To assess differences in composition of stem cell grafts between patients with and without plerixafor treatment To assess differences in hematopoietic recovery, sustained engraftment an immunologic recovery after autologous transplantation

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Age 18 to ≤75 years. Patients with MM in whom for at least two HSCTs cells have to be collected. After steady state mobilization with G-CSF alone: if ≥20/µL and ≤40/µL CD34+ cells in the PB on day 4 of G-CSF administration. Written informed consent. Female patients must be one of the following: postmenopausal, surgically incapable of bearing children, practicing an acceptable method of birth control (effective contraception) during treatment and up to a minimum of 3 months after the last dose of treatment. If a female patient is of childbearing potential, she must have a negative pregnancy test prior to study entry and in monthly intervals up to 3 months thereafter. Patients must be able and willing to comply with all study procedures. Renal impairment: dosage adjustment in patients with CrCl ≤50 mL/min is recommended. Patients with moderate and severe renal insufficiency (CrCl ≤50 mL/min) should have their dose of plerixafor reduced by one-third to 0.16 mg/kg.
