Tocotrienol Against the Progression of End Stage Liver Disease

Summary

The purpose of this Phase 2 trial is to validate the outcome observed in a previous trial that oral Tocotrienol (TCT) attenuates the rise in MELD score over time in patients with end stage liver disease / cirrhosis. The study is double blind and participants will be randomized to take 2 capsules of TCT (200mg) or placebo twice a day for 3 years.
