Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Patients in the study were randomized in a 2:1 ratio (Everolimus: Placebo).

Reporting Groups

	Description
Everolimus	Everolimus was administered orally at a starting dose of 4.5mg/m^2 daily and subsequently titrated to attain whole blood trough concentration of 5 to 15 ng/mL. Dose adjustments were permitted based on safety and whole blood trough concentrations.
Placebo	Matching Placebo was administered orally.

Participant Flow: Overall Study

	Everolimus	Placebo
STARTED	78	39
COMPLETED	2 ^[1]	8
NOT COMPLETED	76	31
Ongoing in Double Blind	76	31

[1]	Completed means discontinued the double-blind treatment period.
