The senolytic combination improved liver fibrosis without disease worsening in nearly half of treated participants while lowering cellular senescence markers.
Why it mattersCellular senescence drives tissue inflammation and fibrosis during aging and chronic disease. This trial provides proof-of-principle evidence in humans that senolytic drugs can reduce senescent cell signatures and reverse organ-level fibrosis.
