This is a randomized, double-blind, multicenter, placebo-controlled, multiple-dose escalating clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity profile of B1344 in patients with NAFLD. Additionally, the trial will conduct preliminary observations on the efficacy of B1344, aiming to provide early proof of concept for B1344 as a therapeutic agent for NASH.
Chinese patients aged between 18 and 75 years;
Patients diagnosed with NAFLD and with a magnetic resonance proton density fat fraction (MRI-PDFF) ≥10% in the screening/baseline period or within one month prior;
Body Mass Index (BMI) ≥24.0 kg/m² or abdominal obesity (male waist circumference ≥90 cm, female waist circumference ≥85 cm);
Fasting blood glucose ≥6.1 mmol/L, or 2-h blood glucose after glucose load ≥7.8 mmol/L, or glycated hemoglobin (HbA1c) ≥5.7%, or history of type 2 diabetes, or Homeostasis Model Assessment Insulin Resistance Index (HOMA-IR) ≥2.5;
Liver biopsy, or clinical diagnosis of cirrhosis based on clinical presentation, biochemical and imaging results, or any of the following criteria: ① FIB-4 score ≥3.48 in the screening/baseline period or within 1 month prior, or liver stiffness value (LSM) ≥15 kPa based on FibroScan; ② liver biopsy results indicating NASH-F4 stage within the previous 24 months; ③ clinical examination signs of liver cirrhosis or splenomegaly during the screening/baseline period; ④ abdominal imaging results showing liver nodules or splenomegaly during the screening/baseline period or within 1 month prior.
