Individual plasma concentrations of SMT C1100 for each of four patients in Groups A (black line), B (red line) and C (blue line). Group A patients received a single 50 mg/kg dose on Day 1 and on the morning of Day 11, with 50 mg/kg bid on Days 2 to 10. Group B and Group C patients received a single 100 mg/kg dose on Day 1 and on the morning of Day 11, with 100 mg/kg bid (Group B) or 100 mg/kg tid (Group C) on Days 2 to 10.

Plot of the average reduction from baseline (estimate, square) of the following plasma markers: creatine phosphokinase (CPK), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALK), gamma-glutamyl transferase (GGT), and albumen (ALB).
Upper and lower 95% confidence intervals for the following time points after dosing shown: Day 7, Day 12, and follow-up (3 days after completion of dosing).
