Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43881   clinical trials with a EudraCT protocol, of which   7295   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

Participants on ACTH, prednisone, or other systemically (non-inhaled or topical) administered steroids should be off the product > 28 days prior to screening. Rifampin and St John’s Wort must be discontinued at least 28 days before Visit 2, study drug initiation.
    Note:
    a. Use of concomitant intranasal or PRN topical steroids for dermatologic reactions and allergic rhinitis are allowed during the study.
    b. This exclusion criterion does not prohibit the use of approved AEDs

    7. Changes in any chronic medications within the 4 weeks prior to the screening visit. All chronic concomitant medications must be relatively stable in dose for at least 4 weeks prior to the screening visit unless otherwise noted.

    9. An active CNS infection, demyelinating disease, degenerative neurological disease, or CNS disease deemed progressive as evaluated by brain imaging (MRI). This includes tumor growth which in the opinion of the investigator could affect primary endpoint seizure control.

    10. Any disease or condition (medical or surgical; other than TSC) at the screening visit that might compromise the hematologic, cardiovascular (including any cardiac conduction defect), pulmonary, renal, gastrointestinal, or hepatic systems; or other conditions that might interfere with the absorption, distribution, metabolism, or excretion of the IP, or would place the participant at increased risk or interfere with the assessment of safety/efficacy. This may include any illness in the past 4 weeks which in the opinion of the investigator may affect seizure frequency.

    11. Hepatic impairment sufficient to affect patient safety, or an AST/SGOT or ALT/SGPT > 3 × the ULN at screening or baseline visits and confirmed by a repeat test.

    12. Biliary impairment sufficient to affect patient safety, or total bilirubin levels > 1.5 × ULN at screening or baseline visit and confirmed by a repeat test. In cases of Gilbert’s Syndrome, resulting in stable levels of total bilirubin greater than ULN, the medical monitor can determine if a protocol exception can be made.

    13. Renal impairment sufficient to affect patient safety, or eGFR < 30 mL/min (calculated using the Cockcroft-Gault formula or Pediatric GFR calculator or Bedside Schwartz), will be excluded from study entry or will be discontinued if the criterion is met post baseline. Cases of temporary renal insufficiency should be discussed with the medical monitor to determine the participant’s study continuation.

    14. Exposed to any other investigational drug or investigational device within 30 days or fewer than 5 half-lives prior to the screening visit. For therapies in which half-life cannot be readily established, the Sponsor’s Medical Monitor should be consulted.

    9. Infección activa del sistema nervioso central (SNC), enfermedad desmielinizante, enfermedad neurológica degenerativa o enfermedad del SNC que se considera progresiva según la evaluación mediante imágenes cerebrales (RM). Esto incluye crecimiento tumoral que, en opinión del investigador, pueda afectar al control de las crisis del criterio de valoración principal.

    10. Cualquier enfermedad o afección (médica o quirúrgica; distinta del CET) en la visita de selección que pueda comprometer el sistema hematológico, cardiovascular (incluido cualquier defecto de conducción cardíaca), pulmonar, renal, gastrointestinal o hepático; u otras afecciones que puedan interferir con la absorción, distribución, metabolismo o eliminación del PEI, o que puedan poner al participante en un mayor riesgo o interferir con la
    evaluación de la seguridad/eficacia. Esto puede incluir cualquier enfermedad en las últimas 4 semanas que, en opinión del investigador, pueda afectar a la frecuencia de las crisis.

    11. Insuficiencia hepática suficiente como para afectar la seguridad del paciente, o un resultado de AST/SGOT o ALT/SGPT >3 × el LSN en las visitas de selección o inicial y confirmado por una repetición de la prueba.

    12.
