Laboratory abnormalities leading to treatment discontinuation included one event of anemia in one patient (0.1 E/100 PY; not associated with the study drug), and one event each of ALT elevation (0.1 E/100 PY) and AST elevation (0.1 E/100 PY) in the same patient (reasonable possibility of being associated with the study drug). The gene discussed is GPT; the disease is anemia.
