Brief Summary

      Tuberous sclerosis complex (TSC) is a genetic disease that leads to mental retardation in
      over 50% of patients, and to learning problems, behavioral problems, autism and epilepsy in
      up to 90% of patients. The underlying deficit of TSC, loss of inhibition of the mammalian
      target of rapamycin (mTOR) protein due to dysfunction of the tuberin/hamartin protein
      complex, can be rescued by everolimus. Everolimus has been registered as treatment for renal
      cell carcinoma and giant cell astrocytoma (SEGA). Evidence in human and animal studies
      suggests that mTOR inhibitors improve learning and development in patients with TSC.
    

Detailed Description

      Randomized double-blind placebo controlled intervention study in children with TSC between
      age 4 and 15 years with an intelligence quotient (IQ) estimated <80 and/or special schooling
      and/or autism spectrum disorder and/or learning disability requiring remedial teaching.

      Patients are randomised to receive everolimus or placebo during a period of 12 months.

             and/or learning disability requiring remedial teaching.

          -  Written informed consent by parents/care-takers, and the patient if he or she is 12
             years or older and cognitively able to consent.
