Phase IIB Results for Efruxifermin
Akero Therapeutics, Inc. released preliminary topline week 96 results from SYMMETRY, a Phase IIb study evaluating the efficacy and safety of its lead product candidate efruxifermin (EFX) in patients with biopsy-confirmed compensated cirrhosis (F4), Child-Pugh Class A, due to metabolic dysfunction-associated steatohepatitis (MASH)
Among patients with baseline and week 96 biopsies (n=134), 39% of patients treated with 50mg EFX (n=46) (p=0.009) experienced reversal of cirrhosis with no worsening of MASH, compared to 15% for placebo (n=47). In the Intent to Treat (ITT) population (n=181), with all missing week 96 biopsies treated as failures, 29% of patients in the 50mg EFX group (n=63) (p=0.031) experienced reversal of cirrhosis with no worsening of MASH, compared to approximately 12% in the placebo group (n=61).
In a subgroup of patients with baseline and week 96 biopsies who were not taking GLP-1 at baseline (n=97), 45% in the 50mg EFX group experienced reversal of cirrhosis with no worsening of MASH (n=29) (p=0.009) compared to 17% for placebo (n=36), suggesting that the observed reversal of cirrhosis was not attributable to GLP-1 therapy.
According to the, press release, 39% of patients with baseline and week 96 biopsies who were treated with efruxifermin 50 mg experienced reversal of cirrhosis with no worsening of MASH, compared to 15% for placebo (P = .009). In the intent-to-treat (ITT) population with all missing week 96 biopsies treated as failures, 29% of patients in the 50 mg efruxifermin group experienced reversal of cirrhosis with no worsening of MASH, compared to approximately 12% in the placebo group (P = .031). “Until today, we’ve not had the prospect of an effective treatment for compensated cirrhosis due to MASH, which is associated with high rates of short-term morbidity and mortality,” Mazen Nourredin, MD, a professor of medicine and transplant hepatologist at Houston Methodist Hospital, and principal investigator for the SYMMETRY study, said in a press release “Now we have reason to be optimistic about the future potential of EFX as a much-needed treatment for cirrhosis, if approved. I’m so happy for my patients and patients all around the world."
.Although resmetirom (Rezdiffra) is currently the only FDA-approved MASH therapeutic, it is only indicated for patients with MASH and moderate to advanced fibrosis, representing a lingering unmet need for those with MASH and cirrhosis.
