Bleomycin lung fibrosis in mice and rats; IPF patient lung fibroblasts in vitro
“In the in vivo bleomycin model of lung fibrosis, nerandomilast was associated with reversal of bleomycin-induced changes in pulmonary remodelling, lung function in mice at 12.5 mg/kg bid and rats at 2.5 mg/kg bid.”
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
EMA: relevance of bleomycin data to progressive pulmonary fibrosis questionable (transient rodent fibrosis)
“However as single dose bleomycin-induced pulmonary fibrosis disease often transiently resolves in rodents, the relevance of the current in vivo data (i.e. mice/rats treated with nerandomilast 8-10 days after bleomycin challenge) for the clinical situation with progressive pulmonary fibrosis (PPF) is questionable.”
