Study summary

Human genetic studies have shown that loss of function (LOF) mutations in HSD17β13 gene have a protective effect on the progression of alcohol-related and non-alcohol-related liver diseases, such as NASH, without significant adverse phenotypes.

VSA006 is a siRNA drug targeting HSD17β13 mRNA in the liver and reduce the protein level of HSD17β13. Based on phase 1 study results in healthy volunteers and NASH/suspected NASH patients, this phase 2 study is designed to evaluate the efficacy, safety, PK profiles and immunogenicity of VSA006 in Chinese NASH patients.

What researchers measure

Primary outcomes

  1. Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH

    No Worsening of NASH is defined as no increase in inflammation, ballooning, or steatosis scores in the NAS score.

    Time frame: At week 52

  2. Percentage of Participants Achieving NASH Improvement with no Worsening of Fibrosis

    NASH Improvement indicates a reduction by at least 2 points in the NAS score, with at least one-point reduction in ballooning without increase in steatosis score.

    Time frame: At week 52

Secondary outcomes

  1. Compared with placebo, the percentage change in serum alanine aminotransferase (ALT)

    Time frame: At week 24, week 52 and week 82

  2. Compared with placebo, the change in liver fat fraction from baseline and liver fat percentage change from baseline

    measured by magnetic resonance imaging-proton density fat fraction (MRI-PDFF)

    Time frame: At week 24 and week 52

  3. Compared with placebo, the percentage of participants with a > 30% decrease in liver fat fraction from baseline

    measured by magnetic resonance imaging-proton density fat fraction (MRI-PDFF)

    Time frame: At week 24 and week 52

  4. Compared with placebo, the change and percentage change in noninvasive markers of fibrosis from baseline: FIB-4, NAFLD fibrosis score, and AST/PLT ratio index (APRI)

    Time frame: At week 24, week 52 and week 82

  5. Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis

    NASH resolution was defined as a NAS score of 0-1 for inflammation, 0 for ballooning, and no increase in steatosis score

    Time frame: At week 52

  6. Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), and their correlation with VSA006

    Time frame: Up to week 82

  7. Maximum observed concentration (Cmax) of VSA006

    Time frame: Pre-dose, 0.5, 1, 2, 4, 8, 12 and 24 hours post dose

  8. Time of maximum concentration of VSA006 (Tmax)

    Time frame: Pre-dose, 0.5, 1, 2, 4, 8, 12 and 24 hours post dose

  9. Area under the concentration-time curve from time zero (pre-dose) to the last quantifiable concentration (AUC0-t) of VSA006

    Time frame: Pre-dose, 0.5, 1, 2, 4, 8, 12 and 24 hours post dose

  10. anti-drug antibodies (ADAs) of VSA006

    Time frame: up to week 82
