Placebo Controlled Study to Assess the Efficacy and Safety of Rapamycin in Drug Resistant Epilepsy Associated With Tuberous Sclerosis Complex

Study Purpose

The purpose 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).

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This is a two-arm, randomized, double-blind, placebo controlled study to evaluate the efficacy, tolerability, and safety of rapamycin versus placebo in a drug resistant epilepsy associated with TSC. The study consists of 3 phases for each patient: screening, dose adjustment blinded phase, core blinded phase, followed by open-label observation. Patients who meet the eligibility criteria will be randomized to receive rapamycin or placebo. The randomization ratio is 1:1. Randomization will be stratified by age, sex and and the number of antiepileptic drugs ever used in the patient's history (up to 3 drugs / more than 3 drugs).

Arms & Interventions


Experimental: Rapamycin arm

Each patient randomized to the rapamycin arm will receive rapamycin in liquid. The rapamycin will be administered in individually calculated doses depending on the body surface of participants

Placebo Comparator: Placebo arm

The patients assigned to the placebo arm will receive placebo in liquid, analogically to the rapamycin group.


Other: - Rapamycin

Rapamycin in liquid administered orally

Other: - Placebo

Placebo in liquid administered orally
