A Prospective Randomized Comparative Four Arm Intervention Study of Efficacy and Safety of Saroglitazar and Vitamin E in Patients with Nonalcoholic Fatty Liver Disease (NAFLD)/ Non-alcoholic Steatohepatitis (NASH)-SVIN TRIAL

Abstract

Background and Aim

Vitamin E is widely prescribed for Non-alcoholic steatohepatitis (NASH).Saroglitazar, a novel dual PPAR ɑ/γ agonist, is approved in India for Non-alcoholic fatty liver disease(NAFLD).No head-to-head comparative study for vitamin E and saroglitazar is available. We studied the efficacy and safety of saroglitazar and vitamin E in NAFLD/NASH.

Materials and Methods

We prospectively randomised 175 NAFLD patients into four arms as; Saroglitazar 4mg daily alone (n=44),vitamin E 800IU daily alone (n=41), vitamin E and saroglitazar combination(n=47) and control arm (n=43). All the baseline variables including Liver stiffness measurement (LSM) and Controlled attenuation parameter (CAP) were recorded.Reassessment was done after 24 weeks of treatment.

Results

The mean age and BMI was 45±11 years and 26±3.6 kg/m² respectively. Compared to control, the decrease in ALT levels with saroglitazar, vitamin E and combination therapy was significant (95% CI, 6.27-28.25,p=0.002, 95% CI, -3.39-18.88, p=0.047 and 95% CI 8.10-29.54,p=0.001 respectively).The reduction in CAP was significant with saroglitazar and combination therapy (95% CI, -31.94-11.99,p=0.015 and 95% CI, -10.48-30.51,p=0.026 respectively).Only combination therapy shows significant reduction in LSM (95% CI, 0.41-1.68,p=0.001).Among glycaemic parameters, both saroglitazar alone and combination therapy significantly improved HBA1C levels (P=0.001 and P=0.015) and only combination therapy significantly improved HOMA-IR (P=0.047).Saroglitazar alone showed significant reduction in TG and LDL levels (P=0.038 and P=0.018), and combination therapy showed significant increase in HDL levels (P=0.024).

Conclusions

Combination of Saroglitazar and vitamin E showed statistically significant reduction of LSM and CAP along with biochemical, glycaemic and lipid parameters.
