HANGZHOU and SHAOXING, China, June 25, 2023 /PRNewswire/ -- Ascletis Pharma Inc. (HKEX:1672, "Ascletis") today announces the poster presentation of ASC42, a novel farnesoid X receptor (FXR) agonistfarnesoid X receptor (FXR) agonist, in combination with PEGylated interferon (PEG-IFN) and entecavir (ETV) in chronic hepatitis B (CHB) patients with 12-week treatment at European Association for the Study of the Liver (EASL) CONGRESS 2023. The summary of the abstract is shown as below:
Title: A phase 2 study of ASC42, a novel farnesoid X receptor (FXR) agonistfarnesoid X receptor (FXR) agonist, in combination with PEGylated interferon (PEG-IFN) and entecavir (ETV) in chronic hepatitis B patients with 12-week treatment
Presenter: Jinzi J. Wu, Ph.D.
Principal Investigator: Prof. Jinlin Hou, Nanfang Hospital of Southern Medical University
Poster Number: SAT-201
Category: Viral Hepatitis B and D
Study Design:
This Phase 2 trial (NCT05107778) was a multi-center, randomized, single-blind, placebo-controlled study conducted in China. Forty-three HBeAg negative, hepatitis B virus (HBV) DNA
Results:
In total, 122, 119, and 107 adverse events (AEs) were reported in 10 mg ASC42, 15 mg ASC42 and PBO cohorts, respectively, and most AEs (94.3%) were mild (grade 1) or moderate (grade 2) in severity. One subject in 15 mg ASC42 cohort experienced a grade 3 serious AE (SAE) of liver function injury with a final outcome of recovered. Pruritus is the most common AE, and study drug-related pruritus was reported in 1 (6.7%), 7 (50%) and 0 (0%) subjects in 10 mg ASC42, 15 mg ASC42 and PBO cohorts, respectively. Pruritus rate of 10 mg ASC42 (6.7%) is lower than other FXR agonistsFXR agonists in non-alcoholic steatohepatitis (NASH) patients.
Conclusion:
In CHB patients, 12-week treatment of 10 mg ASC42 in combination of PEG-IFN-α-2a and ETV was safe and well-tolerated and showed minimum and mild pruritus (6.7%). Previous study indicated that in healthy subjects, 14-day treatment of ASC42 alone demonstrated 471%~1,780% increase of fibroblast growth factor 19 (FGF19) and 53%~91% decrease of 7α-hydroxy-4-cholesten-3-one (C4) at a dose range of 5 mg~15 mg. Data suggest that at the therapeutic dose of 10 mg, the novel FXR agonist ASC42FXR agonist ASC42 is differentiated from other FXR agonistsFXR agonists in terms of pruritus.
