It has been approved in Europe and Japan since the early 1990s to reduce the duration of neutropenia after cytotoxic chemotherapy and bone marrow transplantation and to mobilise peripheral blood stem cells in patients and healthy donors. Trials comparing it with filgrastim show equivalent efficacy at comparable doses. It was never approved in the United States.","status":"established","asOf":"2026-09-08","wikipedia":"https://en.wikipedia.org/wiki/Lenograstim","links":[{"label":"Wikipedia","url":"https://en.wikipedia.org/wiki/Lenograstim"},{"label":"ChEMBL CHEMBL1201567","url":"https://www.ebi.ac.uk/chembl/explore/compound/CHEMBL1201567"}],"tags":["gap-fill","chembl-universe"],"related":[],"cancers":[],"sections":[],"technologies":["cytokine-therapy"],"targets":["csf3r"],"drugs":["filgrastim","pegfilgrastim"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"notes":[],"brand":"Granocyte","modality":"Recombinant glycosylated G-CSF, injection","mechanism":"Activates the G-CSF receptor on neutrophil precursors to drive their proliferation, maturation and release from the marrow.","approvals":[],"mechanismSteps":[],"toxicity":[],"access":[],"regulatoryEvents":[]},"route":"/drugs/lenograstim/","neighbours":{"technology":[{"id":"cytokine-therapy","kind":"technology","name":"Cytokines & engineered cytokines","route":"/technologies/cytokine-therapy/"}],"target":[{"id":"csf3r","kind":"target","name":"G-CSF receptor (CSF3R)","route":"/targets/csf3r/"}],"drug":[{"id":"filgrastim","kind":"drug","name":"Filgrastim (G-CSF)","route":"/drugs/filgrastim/"},{"id":"pegfilgrastim","kind":"drug","name":"Pegfilgrastim","route":"/drugs/pegfilgrastim/"}]}}
