Further study details as provided by Polyphor Ltd.:

Primary Outcome Measures:
  • To assess the ability of POL6326 to mobilise CD34+ hematopoietic stem cells in patients with primary multiple myeloma [ Time Frame: Up to four days ]

    Number of patients achieving the minimal number of CD34+ cells (≥2 x 10 mill/kg BW) collected during one to four cycles of apheresis which are considered necessary and safe to proceed with autotransplantation

    Number of apheresis cycles required to obtain the minimal number of CD34+ cells necessary for autotransplantation (≥2 x 10 mill/kg BW)

Secondary Outcome Measures:
  • To evaluate the safety and pharmacokinetics of POL6326 in patients with multiple myeloma [ Time Frame: 2 months ]
  • To determine the efficacy of POL6326 in reconstitution of immune system after transplantation [ Time Frame: 1 year ]

Enrollment: 21
Study Start Date: April 2009
Study Completion Date: April 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CD34+ mobilisation for transplantation Drug: POL6326
IV infusion of POL6326 followed by apheresis to collect mobilized stem cells from peripheral blood
