NorthSea Therapeutics B.V. (‘NST’, or the ‘Company’), a private, late-stage clinical biotechnology company developing novel strategies to treat metabolic, cholestatic, and fibrotic diseases, today announced that results from the Phase 2b ICONA clinical trial of icosabutate in biopsy-confirmed F1-F3 metabolic dysfunction-associated steatohepatitis (MASH) were published in the Journal of Hepatology.
2023-11-13 NorthSea Therapeutics B.V. Results NorthSea Therapeutics to present ICONA Phase 2b data as an oral late-breaker session at the 2023 AASLD Liver Meeting northseatherapeutics.com ↗
An increase in the proportion of patients achieving NASH resolution without worsening in fibrosis and a ≥2-point decrease in NAS was seen in the 600mg Icosabutate treated arm vs placebo (25.8% vs.11.9%, p=0.03), although the less stringent primary endpoint (not including NAS score) did not reach statistical significance in the overall study population.
2021-11-16 NorthSea Therapeutics B.V. Results Icosabutate latest phase 2b interim data show significant decreases in NASH and fibrosis biomarkers independent of fibrosis stage and disease severity northseatherapeutics.com ↗
Significant decreases in key markers of inflammation and fibrogenesis were comparable or of greater magnitude in patients with stage 2/3 fibrosis vs the overall population after 16 weeks in the ICONA trial
2021-01-08 NorthSea Therapeutics B.V. Results Positive Phase 2b ICONA interim results for icosabutate in NASH patients northseatherapeutics.com ↗
