Investigators found 31% of patients treated with aldafermin 0.3 mg had an improvement in liver fibrosis of at least 1 stage with no worsening of NASH.
Promising new data of aldafermin could finally result in a treatment option for patients with non-alcoholic steatohepatitis (NASH).
A team, led by Stephen A. Harrison, MD, Radcliffe Department of Medicine, University of Oxford, evaluated the safety and efficacy of aldafermin as a potential treatment for patients with NASH.
Aldafermin is an engineered analogue of the gut hormone fibroblast growth factor 19 (FGF19). There is currently no US Food and Drug Administration (FDA) approved therapy for NASH, which affects more than 16 million individuals in the US.
In the randomized, double-blind, placebo-controlled, phase 2b ALPINE 2/3 trial, the investigators examined 171 patients with biopsy-confirmed NASH and stage 2 or 3 fibrosis at 30 sites in the US between May 16, 2019 and September 4, 2020.
Each patient was randomly treated with placebo (n = 43), aldafermin 0.3 mg (n = 43), 1.0 mg (n = 42), or 3.0 mg (n = 43) once daily for 24 weeks. The patients were stratified by fibrosis stage and 85% (n = 145) of the patients completed treatment.
The investigators sought primary endpoints of the improvement in liver fibrosis of at least 1 stage with no worsening of NASH at week 24.
At the conclusion of the study, 19% (n = 7) of patients with biopsies at both baseline and week 24 in the placebo group had an improvement in liver fibrosis of at least 1 stage with no worsening of NASH, without meeting the prespecified significant for dose response (P = 0.55), compared to 31% (n = 11) in the 0.3 mg aldafermin group (difference 12%; 90% CI, −9 to 33; P = 0.11), 15% (n = 5) in the 1.0 mg group (difference −5%; 90% CI, −24 to 13; P = 0.80), and 30% (n = 11) in the 3.0 mg group (difference 10%; 90% CI, −9 to 30; P = 0.12).
For safety, the majority of adverse events were mild or moderate in severity, with diarrhea occurring in 14% (n = 6) of patients in the placebo group, 7% (n = 3) of patients in the 0.3 mg aldafermin group, 12% (n = 5) in the 1.0 mg aldafermin, and 23% (n = 10) of patients in the aldafermin 3.0 mg group.
In addition, the incident rates of serious adverse events and discontinuations because of adverse events were similar between the 4 groups.
“Aldafermin was generally well tolerated but did not produce a significant dose response on fibrosis improvement of at least one stage with no worsening of NASH, despite positive effects on a number of secondary endpoints. The findings of this trial may have implications for the design of future NASH trials,” the authors wrote.
