1.This case is complicated by the presence of elevated serum bilirubin that is primarily unconjugated at baseline, which suggests underlying Gilbert’s Syndrome. It is well known that Gilbert’s Syndrome can become more evident with fasting; therefore, the rise in serum ALT and bilirubin may actually reflect two separate effects of treatment with the drug – 1) drug related elevations in serum ALT and 2) fasting due to drug- induced GI symptoms. In addition, the peak serum ALT measured in this patient was only 4 x ULN and it is very unlikely that larger values were missed since this was measured just 7 days on study drug. In a typical Hy’s Law case, the peak serum ALT is generally > 10 x ULN.
