Abstract

The use of granulocyte-colony stimulating factor (G-CSF) with or without chemotherapy to mobilize hematopoietic progenitor cells (HPCs) can result in significant morbidity in light chain (AL) amyloidosis patients. Plerixafor, a strong inducer and mobilizer of HPCs, can be used as an adjunct to G-CSF to improve mobilization efficiency. We describe the outcomes for combined G-CSF/plerixafor mobilized patients with AL amyloidosis. We reviewed data of 53 consecutive AL amyloidosis patients who underwent combined G-CSF/plerixafor HPC mobilization between May 2011 and October 2017 at our institution. We evaluated patients for HPC collection efficiency, perimobilization toxicity and postautologous hematopoietic cell transplantation (autoHCT) outcomes. Median CD34⁺ cell collection was 12.4 × 10⁶  cells/kg (range 2.5 × 10⁶ to 34.1 × 10⁶  cells/kg) and 45 (85%) patients had collections of ≥5.0 × 10⁶ CD34⁺ cells/kg. There were no mobilization failures or perimobilization mortality. During mobilization, 37 (70%) patients had weight gain (median 1.3 kg, range 0.1-4) but none >10% body weight, 5 (10%) patients had diarrhea, and one patient each had hypotension and cardiac arrhythmia. Among the 31 patients analyzed for CD34 collection efficiency (CE), the median CD34 CE was 47% (range 36-62). At 5 years follow-up 82% and 84% of patients were progression-free and alive, respectively. Our results suggest that G-CSF/plerixafor mobilization is safe, well tolerated, and effective in AL amyloidosis.
