1.  Primary:   Angiomyolipoma Response Rate as Per Central Radiology Review (Double-blind Period)   [ 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 analysis cut-off date (30-June-2011). ]

Measure Type Primary
Measure Title Angiomyolipoma Response Rate as Per Central Radiology Review (Double-blind Period)
Measure Description

Angiomyolipoma response defined as the combination of the following criteria:

reduction in angiomyolipoma volume of ≥ 50% relative to baseline, where angiomyolipoma volume was sum of volumes of all target lesions identified at baseline, and with a confirmatory scan performed approximately 12 weeks later (no sooner than 8 weeks later)• No new angiomyolipoma lesions ≥ 1.0 cm in longest diameter were identified.• There were no kidney increases in volume > 20% from nadir. The patient did not have any angiomyolipoma-related bleeding of ≥ grade 2

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 analysis cut-off date (30-June-2011).  
Safety Issue No  

Population Description

The Full Analysis Set (FAS) is defined according to the Intention-to-Treat principle and consists of all randomized patients. Patients were to be analyzed according to the treatment that they were assigned to at randomization.

2.  Secondary:   Time to Angiomyolipoma Progression as Per Central Radiology Review (Double-blind Period)   [ 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 analysis cut-off date (30-June-2011). ]

Measure Type Secondary
Measure Title Time to Angiomyolipoma Progression as Per Central Radiology Review (Double-blind Period)
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
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 analysis cut-off date (30-June-2011).

[1] The median time to Angiomyolipoma Progression could not be estimated because <50% of patients had an Angiomyolipoma Progression during the time period.
[2] The upper limit was not estimable in the study as it is longer than the estimated time period till data cut-off date (30-June-2011)

3.  Secondary:   Skin Lesion Response Rate as Per Investigator (Only Patients With at Least One Skin Lesion at Baseline)   [ 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 analysis cut-off date (30-June-2011). ]

Measure Type Secondary
Measure Title Skin Lesion Response Rate as Per Investigator (Only Patients With at Least One Skin Lesion at Baseline)
Measure Description Skin lesion response rate in the double-blind period was determined only among patients with at least one skin lesion at baseline, and is the percentage of this group of patients with a best overall skin lesion response on the Physician’s Global Assessment of Clinical Condition (PGA) of either 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 analysis cut-off date (30-June-2011).
