Proteomic Clocks Show Lower Biological Age Across Six Models In Rentosertib Phase 2a Trial, Extending Aging Endpoints Into IPF Drug Development
The study applied six proteomic clocks to serum proteomes from a published phase 2a trial of rentosertib, an AI-designed TNIK inhibitor being developed for idiopathic pulmonary fibrosis and aging-related biology. All six clocks moved in the same direction, but the paper also highlights a central limitation for the field: biomarker shifts still need contextual biological analysis before they can be read as clean anti-aging effects.
