Abstract
Purpose Lipegfilgrastim, a glycoPEGylated recombinant granulocyte colony-stimulating factor (G-CSF), reduces neutropenia duration and febrile neutropenia (FN) incidence in patients with cancer receiving myelosuppressive chemotherapy. A phase 3 trial of lipegfilgrastim was conducted in patients with advanced non-small cell lung cancer (NSCLC) receiving cisplatin/etoposide (which produces mild-to-moderate myelosuppression). Because patients aged >65 years are at higher risk for FN versus younger patients, this post hoc analysis compared outcomes in elderly (>65 years) versus younger participants in this trial. Methods Patients were randomized 2:1 to receive a once-percycle single subcutaneous injection of lipegfilgrastim 6 mg or placebo, with up to 4 cycles of every-3-week cisplatin (day 1) and etoposide (days 1–3). The primary end point was FN incidence during cycle 1. Outcomes were compared across treatment groups and by age groups (≤65 and >65 years). Results For patients aged ≤65 years, FN incidence during cycle 1 was similar in the lipegfilgrastim and placebo groups (3.0 vs 3.2 %, respectively), whereas for elderly patients, there was a reduction in FN incidence with lipegfilgrastim (0 vs 13.3 %, respectively). In both age subgroups, lipegfilgrastim showed a propensity to reduce the incidence and duration of severe neutropenia, time to absolute neutrophil count (ANC) recovery, and depth of ANC nadir. Adverse events were generally similar between groups. Conclusions This analysis suggests that in patients with a higher FN risk, such as the elderly patients of this study, lipegfilgrastim reduces not only the duration of severe neutropenia but also the incidence of FN.
