Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A multicenter trial conducted at 24 sites in 11 countries. As the primary analysis of the core phase of the study favored everolimus over placebo, an open-label extension phase started: patients randomized in placebo were offered to switch on everolimus and those still receiving everolimus at the end of the core phase could continue the treatment.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The trial had a 2:1 randomization in favor of the everolimus arm. 118 patients were randomized to the core phase of the study. 112 patients received everolimus during core and/or extension phase.

Reporting Groups
  Description
Everolimus Study drug was given by continuous oral daily dosing of two 5 mg tablets.
Placebo Placebo was given by continuous oral daily dosing of two 5 mg tablets.

Measure Type Primary
Measure Title Angiomyolipoma Response Rate as Per Central Radiology Review
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.

For the everolimus (core/extension periods) treatment group, 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 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.
