Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the RaRE-TS study is to determine safety, tolerability and efficacy of rapamycin versus placebo in a drug resistant epilepsy associated with tuberous sclerosis complex (TSC).;Secondary Objective: The secondary aim of the study is to ascertain the impact of rapamycin on the TSC- Associated Neuropsychiatric Disorders (TAND) and TSC-associated tumors (brain, kidney, retina and skin lesions) in comparison to placebo. ;Primary end point(s): - comparison of the number of patients with at least 50% reduction of seizures per week in the last month of the core blinded phase in comparison to screening phase in the rapamycin vs placebo group - number of adverse events (according to CTCAE classification) in the rapamycin vs placebo group during the double-blind core phase;Timepoint(s) of evaluation of this end point: -interim analysis -final analyses after the formal final database lock, planned within one month after the last patient last visit in the study

Secondary

MeasureTime frame
Secondary end point(s): -comparison of the number of seizures per week and the number of days free of seizures in the rapamycin vs placebo group, during 12-week treatment in double-blind core phase - severity of adverse events (according to CTCAE) and the number of patients withdrawn from the study due to adverse events in the rapamycin vs placebo group;Timepoint(s) of evaluation of this end point: -interim analysis -final analyses after the formal final database lock, planned within one month after the last patient last visit in the study
