e74a everolimus, an mTOR inhibitor, in the treatment of angiomyolipoma (AML) lesions in patients with subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis complex (TSC). MATERIAL & METHODS: A prospective, double-blind, randomized, placebo-controlled, phase 3 study, EXIST-1 (NCT00789828), examined the effects of everolimus in patients with SEGA associated with TSC. Patients with serial SEGA growth from prebaseline to baseline scans were randomized in a 2:1 scheme to receive everolimus (n=78) or placebo (n=39) stratified by use of enzymeinducing anti-epileptic drugs. The starting dose of everolimus was 4.5 2
mg/m /day and was adjusted to a trough level of 5-15 ng/mL based on patient tolerability. Exploratory analysis of AML response rates was performed in patients (n=44) with >1 target baseline AML lesion with longest diameter >1.0 cm. AML response rate, defined as the proportion of patients with confirmed AML response (reduction in total target AML volume >50% from baseline), was assessed by kidney CT or MRI screening at baseline, 12, 24, and 48 weeks, and then annually. RESULTS: The AML response rate was 53.3% (16/30) and 0% (0/14) for everolimus- and placebo-treated patients, respectively. AML reductions >50% were seen only in everolimus-treated patients (56.5%, 78.3%, 80%) compared with placebo-treated patients (0% at each time point) at week 12, 24, and 48, respectively. Greater percentages of everolimus-treated patients had AML reductions >30% at these same time points (82.6%, 100%, 100% vs. 8.3%, 18.2%, 16.7% for everolimus- and placebo-treated patients, respectively). CONCLUSIONS: Everolimus therapy showed efficacy in reducing AML lesion volume in patients with SEGA associated with TSC who also presented with AML. It may offer a pharmacological treatment option for patients with TSC and concomitant AML and SEGA.
