Updated safety results from EXIST-2: Everolimus therapy for angiomyolipoma (AML) associated with tuberous sclerosis complex (TSC) or sporadic lymphangioleiomyomatosis (sLAM).

4632 Background: EXIST-2 (NCT00790400) is a randomized, double-blind, placebo-controlled, phase 3 trial assessing the efficacy and safety of everolimus, an oral mTOR inhibitor, for treating AML in patients with TSC or sLAM. We have previously reported that everolimus resulted in a significantly higher AML response rate vs placebo (41.8% vs 0%; 95% CI: 23.5–58.4; p<0.0001) with a consistent safety profile (Bissler et al. J Am Soc Nephrol. 22, 2011, Abstract LB-PO3159). Here we present a 90-day safety update. Methods: 118 eligible patients were randomized 2:1 to receive everolimus 10 mg daily (n=79) or placebo (n=39). The primary efficacy endpoint was AML response rate (proportion of patients with best overall AML response status of “response”). Original cut-off date for data analysis was 30 Jun 2011. An updated analysis of the safety data for the safety set (all patients receiving ≥1 dose of double-blind study drug with a valid post-baseline assessment) to 14 Oct 2011 are presented here. Results: As of 14 ...
