Trial Outcomes & Findings for Efficacy and Safety of RAD001 in Patients Aged 18 and Over With Angiomyolipoma Associated With Either Tuberous Sclerosis Complex (TSC) or Sporadic Lymphangioleiomyomatosis (LAM) (NCT NCT00790400)

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.

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.

Efficacy and Safety of RAD001 in Patients Aged 18 and Over With Angiomyolipoma Associated With Either Tuberous Sclerosis Complex (TSC) or Sporadic Lymphangioleiomyomatosis (LAM)

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 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.

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). A complete clinical response (CCR) requires a grading of 0 indicating the absence of disease (histological confirmation is not required). Grades 1, 2, and 3 constitute partial response, indicating improvement of at least 50 percent, but less than 100 percent improvement. For the everolimus (core/extension periods) treatment group, the baseline means the latest value on or before starting everolimus.

Renal Impairment was measured by glomerular filtration rate which was calculated using the Modification of Diet in Renal Disease formula. Percentage of participants with renal impairment was reported. Severe renal impairment was defined as a GFR of \<30ml/min/1.73m2.

Blood samples for biomarker assessment were collected immediately prior to study administration. On-treatment samples was compared to baseline samples with the change from baseline.

Cmin values collected prior to dose administration on the same study day and at 20-28 hours after previous dose, at steady state, and patient did not vomit within 4 hours of previous dose. Samples collected during the first 4 days of dosing were excluded from all analyses.

C2h values collected 1-3 hours after dose administration on the same study day, at steady state, and patient did not vomit between taking previous dose and blood collection. Samples collected during the first 4 days of dosing will be excluded from all analyses.

Time to angiomyolipoma response was defined as the time from the date of randomization until the date of the first documented angiomyolipoma response. 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; no kidney increases in volume \> 20% from nadir; no angiomyolipoma-related bleeding of ≥ grade 2. For the everolimus (core/extension periods) treatment group, the time to angiomyolipoma response is from the start of everolimus. The baseline in the response definition means the latest value on or before starting everolimus.

Duration of angiomyolipoma response was defined as the time from the date of the first documented angiomyolipoma response until the date of the first documented angiomyolipoma progression . Angiomyolipoma response was 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.

Duration of skin lesion response is defined as the time from the date of the first skin lesion response until the date of the first skin lesion progression, according to the PGA (physician's global assessment of clinical condition). A progression is when the disease is worse than at baseline evaluation by \>=25% or more.
