An Exploratory Safety Study to Investigate the Extent of Tumor Cell Mobilization (TCM) After Use of G-CSF Alone or G-CSF Plus Plerixafor in Multiple Myeloma (MM) Patients Who May be Poor Mobilizers of Stem Cells

Phase 2
Completed
Conditions
Multiple Myeloma
Interventions
Drug: Granulocyte-colony stimulating factor (G-CSF)
Registration Number
NCT01753453
Lead Sponsor
Sanofi
Brief Summary

The primary objective of this study is to evaluate tumor cell mobilization (TCM) with non-pegylated G-CSF alone compared with non-pegylated G-CSF plus plerixafor in patients with multiple myeloma (MM) who are potentially poor mobilizers of hematopoietic stem cells (HSC).

Second objectives are to evaluate survival and disease status of G-CSF alone compared with GCSF plus plerixafor, and the efficacy and safety of G-CSF plus plerixafor when used to mobilize stem cells for autologous transplantation.

Inclusion Criteria
  • Patients with a diagnosis of MM in partial response or complete response, who are undergo an autologous hematopoietic stem cell transplantation and could be considered potentially poor mobilizers.
Exclusion Criteria
  • Does not have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
  • Has a history of any acute or chronic leukemia (including myelodysplastic syndrome).
  • Had prior allogeneic or autologous transplantation.
  • Less than 3 to 6 weeks since last anti-cancer therapy.
  • Chemotherapy for mobilization is not allowed.
  • Has bone marrow involvement >10% assessed based on the most recent bone marrow aspirate or biopsy performed prior to first dose of G-CSF.
  • Was treated with G-CSF or other cytokine within 14 days prior to the first dose of G-CSF for mobilization.
  • Has previously received plerixafor.
  • Is known to be HIV positive.
  • Has active hepatitis B or hepatitis C.
  • Has an acute infection within 24 hours prior to dosing or antibiotic therapy within 7 days prior to the first dose of G-CSF.
  • Has hypercalcaemia as evidenced by >1 mg/dL above upper limit of normal (ULN).
  • Previously received investigational therapy within 4 weeks of screening in this protocol or currently enrolled in another investigational protocol during the mobilization phase.
  • Has central nervous system involvement including brain metastases or leptomeningeal disease.
  • Has an electrocardiogram (ECG) or study result indicative of cardiac ischemia or a history of clinically significant rhythm disturbance(arrhythmias), or other conduction abnormality.
  • Has co-morbid condition(s), which may render the patient at high risk from treatment complications or impairs his/her ability to comply with the study treatment and protocol.
  • Has a white blood cell (WBC) count <2.5 x 10^9/L.
  • Has an absolute neutrophil count (ANC) <1.5 x 10^9/L.
  • Has a platelet count <100 x 10^9/L.
  • Has an estimated creatine clearance ≤50 mL/min.
  • Has aspartate aminotransferase/serum glutamic oxaloacetic transaminase (AST/SGOT), alanine aminotransferase/serum glutamic pyruvic transaminase (ALT/SGPT), and total bilirubin ≥2.5 x ULN.
  • Does not have adequate cardiac, and pulmonary function sufficient to undergo apheresis and transplantation.
  • Pregnant or breastfeeding women.
  • Does not agree to use a highly effective method of contraception while on study treatment and for at least 3 months following study treatment.
