89bio biopsy results advance NASH candidate
Promising data for pegozafermin across fibrosis, inflammation and cardio-metabolic endpoints
Biopsy data from a cohort of 89Bio’s Phase I/IIa study suggest pegozafermin may address multiple mechanisms behind NASH, but the compound still faces the challenge of proving statistical significance in a placebo controlled study, a hurdle that has derailed other promising programs.
