Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   41232   clinical trials with a EudraCT protocol, of which   6757   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Key Part A Exclusion Criteria:
    - History or positive test result at screening for human immunodeficiency virus (HIV). The requirement for testing at Screening may be omitted if it is not permitted by local regulations.
    - Current hepatitis C infection (defined as positive Hepatitis C Virus (HCV) antibody and detectable HCV RNA). Participants with positive HCV antibody and undetectable HCV Ribonucleic Acid (RNA) are eligible to participate in the study (United States Centers for Disease Control and Prevention).
    - Current hepatitis B infection (defined as positive for hepatitis B surface antigen (HBsAg) and/or anti-Hepatitis B Core antibody (HBc)). Participants with immunity to hepatitis B from previous natural infection (defined as negative HBsAg, positive anti-HBc, and positive anti-hepatitis B surface antibody (HBs) or vaccination (defined asnegative HBsAg, negative anti-HBc, and positive anti- HBs) are eligible to participate in the study.
    - History of systemic hypersensitivity reaction to tofersen, the excipients contained in the formulation, and if appropriate, any diagnostic agents to be administered during the study.
    - History of confounding neuromuscular or neurological disorder that is expected to have a progressive (i.e., worsening) course during the study, and/or is expected to be associated with elevations in NF, in the opinion of the Investigator.
    - Presence of risk for increased or uncontrolled bleeding and/or risk of bleeding that if not managed optimally could place a participant at an increased risk for intraoperative or postoperative bleeding.
    - Significant cognitive impairment, clinical dementia, or unstable psychiatric illness, including psychosis, suicidal ideation, suicide attempt, or untreated major depression ≤ 90 days of Screening, which in the opinion of the Investigator would interfere with the study procedures.
    - Anticipated need, in the opinion of the Investigator, for administration of any antiplatelet or anticoagulant medication (e.g., clopidogrel) that cannot be safely continued or held for an LP procedure, if necessary, according to local or institutional guidelines and/or Investigator determination.
    - Treatment with another investigational drug (including investigational drugs for ALS through compassionate use programs), biological agent, or device within 1 month or 5 half-lives of study agent, whichever is longer. Specifically, no prior treatment with small interfering RNA, stem cell therapy, or gene therapy is allowed.
    - Current enrollment or a plan to enroll in any interventional clinical study in which an investigational treatment, biological agent, device, or approved therapy for investigational use. Participation in a noninterventional study focused on ALS natural history may be allowed at the discretion of the Investigator.

    NOTE: Other protocol defined Inclusion/Exclusion criteria will apply.
    Criterios Clave de Exclusión de la Parte A:

    - Presencia de riesgo de hemorragia aumentada o incontrolada y / o riesgo de hemorragia que, si no se maneja de manera óptima, podría colocar a un participante en un mayor riesgo de hemorragia intraoperatoria o posoperatoria.
    - Deterioro cognitivo significativo, demencia clínica o enfermedad psiquiátrica inestable, incluida psicosis, ideación suicida, intento de suicidio o depresión mayor no tratada ≤ 90 días de selección, que en opinión del investigador interferiría con los procedimientos del estudio.
    - Necesidad anticipada, en opinión del investigador, de la administración de cualquier medicamento antiplaquetario o anticoagulante (p. Ej., Clopidogrel) que no se puede continuar o mantener de forma segura para un procedimiento de LP, si es necesario, de acuerdo con las pautas locales o institucionales y / o la determinación del investigador .
    - Tratamiento con otro medicamento en investigación (incluidos medicamentos en investigación para ELA a través de programas de uso compasivo), agente biológico o dispositivo dentro de 1 mes o 5 vidas medias del agente del estudio, lo que sea más largo. Específicamente, no se permite ningún tratamiento previo con micro ARN interferentes, terapia con células madre o terapia génica.
