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   43845   clinical trials with a EudraCT protocol, of which   7282   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Two longitudinal biomarker substudies will evaluate the effects of study treatment on the underlying pathophysiology of AD using Amyloid PET and/or CSF biomarkers. Participation in the substudies is optional and will require specific consent that will not affect enrollment or treatment in the main study.
    En dos subestudios longitudinales de biomarcadores se evaluarán los efectos del tratamiento del estudio sobre la fisiopatología subyacente de la EA empleando TEP amiloide y/o biomarcadores del LCR. La participación en los subestudios es opcional y requerirá un consentimiento específico que no afectará a la inclusión o al tratamiento en el estudio principal.
    E.3Principal inclusion criteria
    1. MCI due to Alzheimer’s disease or Mild Alzheimer’s disease according to the National Institute of Aging – Alzheimer’s Association (NIA-AA) core clinical criteria and must have all of the following:
    a. MMSE score equal to or greater than 24
    b. CDR global score of 0.5
    c. CDR Memory Box score of 0.5 or greater
    2. A history of subjective memory decline with gradual onset and slow progression over the last 1 year before Screening; this MUST be corroborated by a study partner
    3. Cognitive impairment of at least 1 SD from age-adjusted norms in total recall or delayed recall on the ISLT.
    4. Positive biomarker for brain amyloid pathology as indicated by at least 1 of the following:
    a. PET assessment of amyloid imaging agent uptake into brain. Note: Amyloid PET screens will be performed according to local regulatory guidelines and thus may be restricted for those subjects who are not suitable for lumbar puncture (LP) to obtain CSF for testing of eligibility.
    b. CSF assessment of Aβ(1-42) NOTE: Subjects may undergo both the Amyloid PET and CSF assessments, but need a positive amyloid result in only 1 of the 2 procedures to confirm eligibility. Subjects who consent to Amyloid PET or CSF for eligibility purposes are not required to participate in the Amyloid PET or CSF longitudinal substudies. Use of a historical Amyloid PET (conducted within 12 months before the planned date of randomization) is acceptable for determination of eligibility but will not suffice for the baseline assessment if the subject wishes to consent to the Amyloid PET longitudinal substudy. The historical imaging data must be made available to the sponsor.
    5. Male or female subjects between 50 and 85 years of age, inclusive at the time of consent
    6. If receiving an AChEI or memantine or both for AD, must be on a stable dose for at least 12 weeks prior to Randomization. Treatment-naïve subjects with AD can be entered into the study.
    7. Subjects must have been on stable doses of all other (ie, non-AD related) permitted concomitant medications for at least 4 weeks prior to Randomization, except for medications which are administered as short courses (eg, up to 3 weeks unless discussed and agreed with Medical Monitor) of treatment (eg, anti-infectives) or which are to be used on a Pro re nata (PRN) basis. Subjects who require a short course of treatment, such as an anti-infective, may be randomized once the acute illness has completely resolved, even if the concomitant medication continues.
    8. Must have an identified study partner (defined as a person able to support the subject for the duration of the study and who spends at least 8 hours per week with the subject). The study partner must provide written informed consent. In addition, this person must be willing and able to provide follow-up information on the subject throughout the course of the study. This person must, in the opinion of the investigator, spend sufficient time with the subject on a regular basis such that they can reliably fulfill the requirements of being a study partner. A study partner need not be living in the same residence with the subject. For such a study partner not residing with the subject, the investigator has to be satisfied that the subject can contact the study partner readily during the times when the study partner is not with the subject. Study partners need to provide input to the following assessments: CDR, FAQ, EQ-5D, QOL-AD, Zarit’s Burden Interview, and the clinical assessment of suicidality. Consideration can occur for the investigator to decide whether the study partner can provide information over the telephone or whether the study partner must attend the study visits in person with the subject.
    1. DCL debido a la enfermedad de Alzheimer o enfermedad de Alzheimer leve según los criterios clínicos principales del National Institute of Aging – Alzheimer’s Association (NIA-AA) y deben presentar todas las siguientes condiciones:
    a. Puntuación del MMSE igual o superior a 24
    b. Puntuación global del CDR de 0,5
    c. Puntuación de la caja de memoria del CDR de 0,5 o superior
    2. Antecedentes de deterioro subjetivo de la memoria de aparición gradual y progresión lenta durante el último año antes de la selección; esto DEBE corroborarlo una pareja del estudio
    3. Deterioro cognitivo de al menos 1 DE con respecto al estándar ajustado para la edad en el recuerdo total o el recuerdo diferido de la ISLT.
    4. Biomarcador positivo para patología amiloide determinado por al menos 1 de los siguientes métodos:
    a. Evaluación TEP de las imágenes de captación de amiloide cerebral. Nota: Las pruebas de TEP amiloide se realizarán de acuerdo con las pautas normativas locales y, por lo tanto, estarán restringidas a aquellos pacientes a los que no se puede practicar una punción lumbar (PL) para obtener LCR para las pruebas de aptitud.
    b. Evaluación de Aβ(1-42) en el LCR
    NOTA: Los pacientes podrán someterse a las dos evaluaciones de TEP amiloide y LCR, aunque requieren un resultado amiloide positivo solamente en 1 de los 2 procedimientos para confirmar su idoneidad. Los pacientes que dan su consentimiento para el TEP amiloide o el LCR para fines de idoneidad no tendrán que participar en los subestudios longitudinales de TEP amiloide o LCR. El uso de un TEP amiloide histórico (realizado en el plazo de 12 meses antes de la fecha de aleatorización planificada) es aceptable para la determinación de la idoneidad, pero no será suficiente para la evaluación inicial si el paciente desea dar su consentimiento para el subestudio longitudinal de TEP amiloide. Se deberán facilitar los datos radiográficos históricos al promotor.
    5. Pacientes de sexo masculino o femenino de entre 50 y 85 años de edad, ambos inclusive, en el momento del consentimiento.
    6. Si está recibiendo un AChEI o memantina o ambos para la EA, debe haber recibido una dosis estable durante al menos 12 semanas antes de la aleatorización. Los pacientes sin tratamiento previo para la EA podrán incluirse en el estudio.
    7. Los pacientes deberán haber recibido una dosis estable de todos los demás (es decir, no relacionados con la EA) medicamentos concomitantes durante al menos 4 semanas antes de la aleatorización, con la excepción de los medicamentos que se administran en pautas cortas (p. ej., hasta 3 semanas a menos que se acuerde otra cosa con el monitor médico) de tratamiento (p. ej., antiinfecciosos, corticosteroides orales) o que deban emplearse de acuerdo con un régimen Pro Re Nata (PRN). Los pacientes que requieran una pauta de tratamiento corta, como antiinfecciosos o corticosteroides orales, podrán ser aleatorizados una vez se haya resuelto completamente la enfermedad aguda, incluso si continúan con la medicación concomitante.
    8. Deben contar con una pareja del estudio identificada (definida como una persona capaz de asistir al paciente durante el estudio y que pasa al menos 8 horas a la semana con el paciente). La pareja del estudio debe proporcionar un consentimiento informado por escrito. Además, esta persona debe estar dispuesta y ser capaz de proporcionar información de seguimiento acerca del paciente a lo largo del estudio. Esta persona debe, en opinión del investigador, pasar tiempo suficiente con el paciente de forma regular, de manera que pueda cumplir con fiabilidad los requisitos que conlleva ser una pareja del estudio. Una pareja del estudio no tiene por qué vivir en el mismo domicilio que el paciente. Para una pareja del estudio que no reside con el paciente, el investigador debe asegurarse de que el paciente puede ponerse en contacto con la pareja del estudio inmediatamente durante los periodos en que la pareja del estudio no está con el paciente. Las parejas del estudio tienen que participar en las siguientes evaluaciones: CDR, FAQ, EQ 5D, QOL-AD, Entrevista de Carga del Cuidador de Zarit, NPI-10 y la evaluación clínica de las tendencias suicidas. El investigador será quien considere la decisión de si la pareja del estudio puede proporcionar información por vía telefónica o si la pareja del estudio debe acudir personalmente a las visitas del estudio con el paciente.
    E.4Principal exclusion criteria
    1. Females who are breastfeeding or pregnant at Screening or Baseline (as documented by a positive
    beta-human chorionic gonadotropin test. A separate baseline assessment is required if a negative
    screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
    Females of child-bearing potential who:
    •Within 28 days before study entry, did not use a highly effective method of contraception,
    which includes any of the following:
    o total abstinence (if it is their preferred and usual lifestyle)
    o an intrauterine device or intrauterine hormone-releasing system
    o an oral contraceptive (Subject must be on a stable dose of the same oral contraceptive product for at least 28 days before dosing and throughout the study and for 28 days after study drug discontinuation.)
    o have a vasectomized partner with confirmed azoospermia.
    •Do not agree to use a highly effective method of contraception (as described above) throughout the entire study period and for 28 days after study drug discontinuation.
    For sites outside of the European Union, it is permissible that if a highly effective method of contraception is not appropriate or acceptable to the subject, then the subject must agree to use a
    medically acceptable method of contraception, ie, double-barrier methods of contraception such
    as condom plus diaphragm or cervical/vault cap with spermicide.
    NOTE: All females will be considered to be of child-bearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (ie, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing)
    2. Any condition that may be contributing to cognitive impairment above and beyond that caused by
    the subject’s AD
    3. Subjects with a history of seizures within 5 years of Screening or subjects with disturbance likely
    to be due to seizures within 5 years of Screening
    4. History of transient ischemic attacks (TIA) or stroke within 12 months of Screening
    5. Modified Hachinski Ischemia Score greater than 4 at Screening
    6. Any of the following psychiatric symptoms:

    • Has a “yes” answer to C-SSRS suicidal ideation items 4 or 5, or any suicidal behavior within 6 months before Screening, at Screening, or at the Randomization Visit, or has been hospitalized or treated for suicidal behavior in the past 5 years before Screening
    7. Have any contraindications to MRI scanning, including cardiac pacemaker/defibrillator, ferromagnetic metal implants (eg, in skull and cardiac devices other than those approved as safe
    for use in MRI scanners) or
    • Have any evidence of other clinically significant lesions that could indicate a dementia diagnosis other than AD on brain MRI at Screening.
    • Exhibit other significant pathological findings on brain MRI at Screening, including but not limited to: an area of superficial siderosis; evidence of cerebral vasogenic edema; evidence of cerebral contusion, encephalomalacia, aneurysms, vascular malformations, or infective lesions; evidence of multiple lacunar infarcts or stroke involving a major vascular territory, severe small vessel, or white matter disease; space occupying lesions; or brain tumors (however, lesions diagnosed as meningiomas or arachnoid cysts and less than 1 cm at their greatest diameter need not be exclusionary).
    8. Subjects who have a history of moderate to severe hepatic impairment (eg, Child-Pugh Class B or C). Any 2 of the following criteria at Screening would exclude the subject: INR ≥ 1.7; bilirubin ≥ 1.5 × ULN; albumin < LLN; ascites or hepatic encephalopathy. Please note that a single significant abnormality could meet criteria for moderate impairment. (revised per Amendment 01)
    9. Results of laboratory tests conducted during screening that are outside the following limits:
    • Absolute lymphocyte count (ALC) below Lower Limit of Normal (LLN) or below 800 per mm3 (whichever is higher); ALC will be derived from the complete blood count (CBC) with differential representing the normal lymphocytes (with atypical lymphocytes removed and presented as a separate count if they are present) and calculated by the white blood cell count × percentage of lymphocytes. (revised per Amendment 01)
    • Thyroid stimulating hormone (TSH) above normal range. Other tests of thyroid function with results outside the normal range should only be exclusionary if they are considered clinically significant by the investigator (this applies to all subjects whether or not they are taking thyroid supplements)
    ................ Please refers to study protocol for further exclusion criteria
    1. Mujeres en periodo de lactancia o embarazadas en el momento de la selección o el inicio (documentado mediante una prueba positiva de gonadotropina coriónica humana beta).
