Sorry, just re-read the news and saw the elevated LTEs issue was with the 100mg cohort, not the 70mg group. Still a possibility I guess, but less likely the 100mg group would resort to other drugs when the 70mg group didn't...

Could also have been caused by patients supplementing the very low 70mg dose with Acetaminophen because it isn't powerful enough to ease their pain.[/quote]
