Effects of Empagliflozin on Fibrosis and Cirrhosis in Chronic Hepatitis B Patients

Chronic hepatitis B (CHB) affects 257million individuals worldwide. In 2017, it caused around 39.7 million cases of cirrhosis and 0.4 million cirrhosis-related deaths in 2017. However, there is no specific treatment for liver fibrosis/cirrhosis. Although nucleos(t)ide analogues (NAs) profoundly suppress viral replication, fibrosis/cirrhosis progression can still occur in NA-treated patients. Sodium-glucose cotransporter type-2 (SGLT2) inhibitors are antidiabetic drugs that may prevent fibrosis/cirrhosis progression by reducing hepatic steatosis/inflammation, dampening renin-angiotensin aldosterone system (RAAS) activation, and reducing fluid retention, effects of which are independent of glycemic control. Clinical studies in diabetic patients show SGLT2 inhibitors reduce hepatis steatosis/inflammation, regress ascites (a cirrhotic complication), and improve liver function parameters and survival prognosis in terms of model for end-stage liver disease (MELD) score. There are currently no randomized controlled trials (RCTs) on role of SGLT2 inhibitors in preventing fibrosis/cirrhosis progression in CHB patients. Magnetic resonance elastography (MRE) and transient elastography (TE) are non-invasive techniques for liver stiffness measurement (LSM), although MRE is more accurate than TE. The investigators propose a double-blind, randomized, placebo-controlled trial to compare effect of empagliflozin (an SGLT2 inhibitor) with placebo (1:1 ratio) in preventing fibrosis progression in both diabetic and non-diabetic NA-treated CHB patients with significant/advanced fibrosis or compensated cirrhosis. 108 patients will be randomly sampled from our pre-existing TE database. Empagliflozin 10mg daily will be given to treatment arm. Placebo pills will be manufactured identical in appearance to empagliflozin. Subjects will receive active or placebo pills for three years, and undergo clinical, anthropometric and laboratory assessments (at baseline, weeks 8, 16, and every 4 months thereafter). They will undergo LSM by TE at baseline, end of first, second and third year, and by MRE at baseline and end of third year. Primary outcome is difference in change to liver stiffness (measured by MRE) from baseline between the two groups at the end of third year. The study results will determine whether SGLT2 inhibitors can prevent hepatic fibrosis/cirrhosis progression in NA-treated CHB patients.

DICE Study- Diastolic Improvement With Carvedilol & Empagliflozin in Patients With Cirrhosis

1. This proposed double-blind placebo controlled randomized controlled trial incorporates recent advances in management of heart failure and portal hypertension using the SGLT-2 inhibitor i.e. EMPAGLIFLOZIN. The drug has been found to be useful in large trials on heart failure with preserved ejection fraction in the general population with improvement in MASLD progression, with improvement in body weight and hepatic steatosis but no change in liver fibrosis. 2. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been shown to reduce the development and progression of heart failure in patients with type 2 diabetes and in those with heart failure and a reduced and preserved ejection fraction. In patients with cirrhosis safety of empagliflozin in a dose of 10 mg has been demonstrated. 3. Prevention of decompensation related events in cirrhosis is the key endpoint of any liver-directed therapy as the median survival in the compensated state exceeds 10 years but median survival in the decompensated state approximates 1.5 years. Previous data has demonstrated the risk of hepatic decompensation acute kidney injury and poor survival in patients with cirrhosis and heart failure with preserved ejection fraction (HFpEF) i.e. LVDD a large subset of whom meet criteria for CCM.
