1.  Primary:   Angiomyolipoma Response Rate as Per Central Radiology Review   [ Time Frame: From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to 5.7 years ]

2.  Secondary:   Time to Angiomyolipoma Progression as Per Central Radiology Review   [ Time Frame: From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to about 5.7 years ]

Measure Type Secondary
Measure Title Time to Angiomyolipoma Progression as Per Central Radiology Review
Measure Description

Time to angiomyolipoma progression (TTAP) is defined as time from date of randomization to date of first documented angiomyolipoma progression. Angiomyolipoma progression was defined as one or more of the following: Increase from nadir of ≥ 25% in angiomyolipoma volume to value greater than baseline; the appearance of a new angiomyolipoma ≥ 1.0 cm in longest diameter; an increase from nadir of 20% or more in the volume of either kidney to a value greater than baseline; angiomyolipoma-related bleeding grade ≥ 2.

For the everolimus (core/extension periods) treatment group, the time to angiomyolipoma progression is defined starting from the start of everolimus. The baseline means the latest value on or before starting everolimus.

Time Frame From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to about 5.7 years  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
The Full Analysis Set (FAS) is defined according to the Intention-to-Treat principle and consists of all randomized patients.

Reporting Groups
  Description
Everolimus Randomized (Core Period) Study drug was given by continuous oral daily dosing of two 5 mg tablets.
Placebo Randomized (Core Period) Placebo was given by continuous oral daily dosing of two 5 mg tablets.
Everolimus (Core and/or Extension Period) Patients initially randomized in everolimus and patients initially randomized in placebo but who crossed-over to everolimus during extension.

8.  Secondary:   Time to Angiomyolipoma Response - Only Everolimus Patients With Angiomyolipoma Response   [ Time Frame: From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to 5.7 years ]

9.  Secondary:   Duration of Angiomyolipoma Response - Only Everolimus Patients With Angiomyolipoma Response   [ Time Frame: From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to about 5.7 years ]

10.  Secondary:   Duration of Skin Lesion Response - Only Everolimus Patients With Best Overall Skin Lesion Response of Complete Clinical Response (CCR) or Partial Response (PR)   [ Time Frame: From date of randomization until the earliest date of first documented AML progression, date of further anti-AML medication (including open-label Everolimus)/surgery or up to about 5.7 years ]
