group (n=219) from 1.75 L at baseline in the parent
study for patients enrolled from QUEST4
Results are descriptive. Definitive conclusions cannot be made.
Data were not multiplicity controlled and there are limitations associated
with open-label study design, including lack of comparator arm, decreasing
sample size, and potential continued involvement of responders and
attrition of non-responders.
