Research Efficacy Snapshot

Published efficacy percentages cited in PubMed trials and named-expert reports about Filgrastim. Each line links to the original source.

  • "Filgrastim was administered by physician discretion to seven patients (31.8%), and the median duration of neutropenia after lymphodepleting therapy was significantly shorter for those patients who received filgrastim (5 vs 15 days, P = .016)." · Gaut D et al, 2021 PubMed
  • "Five patients (22.7%) developed infection in the 30 days post-CAR T-cell therapy with three patients being Grade 3 or higher." · Gaut D et al, 2021 PubMed
  • "Among the seven patients that received filgrastim, six patients (85.7%) and four patients (57.1%) had evidence of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), respectively." · Gaut D et al, 2021 PubMed
  • "Among the 15 patients that did not receive filgrastim, 8 patients (53.3%) and 7 patients (46.7%) had evidence of CRS and ICANS, respectively." · Gaut D et al, 2021 PubMed
  • "However, more recent meta-analyses of placebo-controlled randomized trial data show falling costs due to biosimilar competition and absolute overall survival gains of 3.2% (95% CI: 2.1-4.2%) from filgrastim support of cytotoxic chemotherapy." · Cornes P et al, 2019 PubMed
