Prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia with lipegfilgrastim in patients with non-Hodgkin lymphoma (NADIR study).

OBJECTIVE: The prospective non-interventional study (NIS) NADIR was designed to evaluate both effectiveness and safety of prophylactic use of lipegfilgrastim (Lonquex® ), a glycopegylated granulocyte colony-stimulating factor, in cancer patients with different tumor entities undergoing chemotherapy in routine clinical practice. The primary objective was incidence of severe neutropenia, febrile neutropenia (FN), and neutropenia-associated complications. METHOD: NADIR was a national, multicenter, prospective NIS. RESULTS: Here, we present the data on patients with non-Hodgkin lymphoma (NHL). Final analysis comprised 337 NHL patients having received ≥1 administration of lipegfilgrastim. Primary prophylaxis with lipegfilgrastim was documented in 78.7% of patients with high risk to develop FN. In total, ≥1 severe neutropenia (grade 3/4) was reported in 115 (34.1%) patients and ≥1 event of FN documented in 15 (4.5%) patients. Grade 3/4 infections were reported in 22 (6.5%) patients overall. Most frequently reported adverse events (AEs) related to lipegfilgrastim in total were bone pain (5.4%), leukocytosis (2.1%), back pain (1.8%), platelet count decreased (1.2%), and myalgia (1.2%). Fatal serious AEs were documented in 9 (2.7%) patients; none were attributable to lipegfilgrastim. CONCLUSION: Prophylaxis or therapeutic intention with lipegfilgrastim in NHL patients in routine clinical practice showed similar effectiveness and safety as demonstrated in the pivotal trials.
