- CONFIDENTIAL - 27 FGF21 DEVELOPMENT LANDSCAPE: SUMMARY Consideration Fc - FGF21 Fusion Protein (Akero) Pegylated FGF21 (BMS or 89Bio) Patient Population: NASH diagnosed only by biopsy; NASH patients have more advanced disease and worse comorbidities Biopsy - confirmed NASH BMS: biopsy - confirmed NASH; 89Bio: ~20% biopsy - confirmed NASH * Histology: Fibrosis only histological endpoint correlated with liver outcomes Demonstrated fibrosis improvement by histology BMS: histology data pending 89Bio: no histology data Liver Fat Reduction: Max reduction requires inhibition of both hepatic fat synthesis and adipose tissue lipolysis 71% (50mg QW) BMS: 38% (10mg QD) 89Bio: 60% (27mg QW * ) Liver Enzymes (LFTs): Reductions indicate improved liver health Large reductions in LFTs; Consistent dose response BMS/89Bio: Smaller effects on LFTs Lipids: Cardiovascular risk #1 cause of mortality for NASH patients. Reflects liver and adipose effects Robust and consistent TG and HDL - C effects BMS/89Bio: Smaller effects on TG and HDL - C Glycemic Control: Improvement in HbA1c mediated by peripheral insulin sensitization; 50% NASH patients diabetic Significant decrease in HbA1c BMS: HbA1c not reported 89Bio: no significant change in HbA1c Safety & Tolerability: Baseline patient population influences profile; Mild GI events common for FGF21 in NASH patients In line with FGF21 class BMS: In line with FGF21 class 89Bio: ~80% NAFLD * EFX delivered numerically largest effects, a clear dose response, with maximal or near - maximal effect at 50mg QW * Subjects with biopsy - confirmed NASH were present only in the 18mg QW & 18 Q2W cohorts (Loomba et al., 2020 AASLD Poster #LP34)
