Long-Term Follow-up Study for Non-Hodgkin's Lymphoma Patients Who Received Study Treatment (Plerixafor or Placebo) in the AMD3100-3101 Study (NCT00103610).

This is a long-term observational study of patients who received at least one dose of study treatment (plerixafor or placebo) in a multicenter, randomized, double blind, placebo-controlled investigational study to evaluate granulocyte colony stimulating factor (G-CSF) plus AMD3100 versus G-CSF plus placebo to mobilize and transplant Non-Hodgkin's Lymphoma (NHL) patients (protocol AMD3100-3101 \[NCT00103610\]). The objective of this study is to assess progression-free survival and overall survival of patients treated with at least 1 dose of study treatment (placebo or plerixafor) for a period of 5 years following the first dose of study treatment (placebo or plerixafor) in protocol AMD3100-3101 (NCT00103610).
