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.4Principal exclusion criteria
    1. Patients treated with dexamethasone > 2 mg/day or equivalent (i.e. 13 mg/day of prednisone, or 53 mg/day of hydrocortisone) within 14 days before the first EO2401 administration, unless required to treat an adverse event. Note, inhaled steroids and adrenal replacement steroid doses > 13 mg daily prednisone equivalents are permitted. Thus, patients needing hydrocortisone replacement therapy due to prior or ongoing mitotane therapy can receive hydrocortisone doses > 53 mg/day, i.e. also in the normally used range of 60-80 mg/day, and still be included in the trial.
    2. Patients with prior treatment with compounds targeting PD-1, PD-L1,
    CTLA-4, or similar compounds where general resistance against
    therapeutic vaccination approaches might have developed (e.g. defects
    to the cellular antigen processing/presentation machinery, including
    mutations in Janus kinas [JAK] 1, JAK2, and β-2-microglobulin [B2M])
    allowing tumor cells to avoid recognition and attack by immune cells.
    3. Patients with prior exposure to EO2401, e.g. patients treated in Cohorts 2B or 3B of the current trial cannot be re-enrolled for treatment also in Cohorts 2A or 3A.
    4. Patients treated with immunotherapy (meaning immunostimulatory or
    immunosuppressive therapy; beside excluded, or allowed, compounds
    per other inclusion/exclusion criteria specifications), radionuclide
    therapy, radiotherapy, cytoreductive therapy, or received treatment with
    any other investigational agent within 28 days before the first EO2401
    administration. Note, for patients with ACC continued treatment with
    mitotane during this trail is allowed provided tumor progression on this
    therapy has been demonstrated under therapeutic plasma level or at
    maximum individual tolerated dose and mitotane plasma level
    monitoring is maintained during the trial (mitotane might have been
    given in the adjuvant and/or established disease settings as long as
    progression on this therapy before trial inclusion has been documented).
    For patients with MPP, concurrent therapy with octreotide is allowed
    provided tumor progression on this therapy has been demonstrated;
    concurrent therapy with bisphosphonates (e.g. zoledronic acid) or
    denosumab is also allowed.
    5. Patients with ACC with more than three organs involved by disease,
    combined with high ki-67 expression in tumor (≥ 20%), and
    unresectable primary tumor.
    6. Patients with ACC and uncontrolled cortisol secretion (according to
    the judgement of the treating physician).
    7. Patients with MPP and uncontrolled blood pressure (according to the
    judgement of the treating physician).

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint regarding safety and tolerability of EO2401 in
    combination with nivolumab is a descriptive medical assessment of the
    combined profile of incidences of adverse events (AEs), treatmentemergent
    AEs (TEAEs), serious AEs (SAEs), deaths, reasons for treatment discontinuation/delays, and laboratory abnormalities using the NCI-CTCAE v5.0 grading system.
    El criterio de valoración principal con respecto a la seguridad y la tolerabilidad de EO2401 en combinación con nivolumab es una evaluación médica descriptiva del perfil combinado de incidencias de acontecimientos adversos (AA), AA durante el tratamiento (AADT), AA graves (AAG), muertes, motivos para interrumpir/retrasar el tratamiento y anomalías de laboratorio mediante el sistema de clasificación NCI CTCAE v5.0.
    E.5.1.1Timepoint(s) of evaluation of this end point
    AEs will be monitored throughout the study. AEs are collected from the date of the patient's signing the ICF until 30 days after the final administration of study drug. SAEs with a plausible causal relationship to study drug will be reported from the date of the patient's signing the ICF until indefinitely (regardless of time elapse from the final study drug administration). An AE causally not related to study drug will be monitored (followed-up) until resolution, stabilization, or end of the clinical trial. Clinically relevant laboratory abnormalities will be followed up until they return to normal or become stabilized (permanent condition). Any AE with a plausible causal relationship to study drug as well as all SAEs will be followed up until the event has resolved or
    stabilized.
    Los AA serán monitorizados durante todo el estudio. Los AA se recopilan desde la fecha en que el paciente firma el CI hasta 30 días después de la administración final del fármaco del estudio. Los AAG con una relación causal plausible con el fármaco del estudio se informarán desde la fecha en que el paciente firme el CI hasta indefinidamente .Un AA causalmente no relacionado con el fármaco del estudio será monitorizará hasta la resolución, estabilización o finalización del ensayo clínico. Las anomalías de laboratorio clínicamente relevantes serán seguidas hasta que vuelvan a la normalidad o se estabilicen (condición permanente). Cualquier AA con una relación causal plausible para estudiar el fármaco, así como todos los AAG, serán seguidos hasta que el evento se haya resuelto o estabilizado
    E.5.2Secondary end point(s)
    Secondary endpoints include:
    • Percentage of patients with shown immunogenicity (expansion of
    specific T cells comparing samples taken at baseline versus on treatment
    n an individual patient determining if the patient has a positive response
    to the immunization, or not) in relation to EO2316, EO2317, EO2318, and
    UCP2 that compose EO2401 by interferon-gamma (IFN-γ) enzyme-linked
    immunospot (ELISpot), and if needed by intracellular cytokines staining,
    or multimers staining assays. Cross reactivities with the human TAAs
    IL13Rα2, FOXM1, and BIRC5/survivin will also be evaluated by the same
    methods.

    time interval from the date of first study treatment administration to the
    date of progression (by RECIST 1.1 or iRECIST criteria) or death due to
    any cause, whichever is earlier. Patients without progression or death
    are to be censored at the time of the last tumor assessment.
    • OS defined as the time interval from the date of first study treatment
    administration to the date of death due to any cause. Patients alive will
    be censored at the date of the last documented follow-up.
    Entre los criterios de valoración secundarios se incluyen:
    •Porcentaje de pacientes que muestran inmunogenia (expansión de linfocitos T específicos comparando muestras tomadas al inicio con las tomadas durante el tratamiento para un paciente concreto, determinando si el paciente presenta una respuesta positiva a la inmunización o no) en relación con EO2316, EO2317, EO2318 y UCP2, que componen EO2401, mediante inmunotransferencia por manchas (ELISpot) ligada a la enzima interferón-γ (IFN-γ) y, si es necesario, mediante la tinción de citocinas intracelulares o ensayos de tinción multímeros. También se evaluarán por los mismos métodos las reactividades cruzadas con los AAT humanos IL13Rα2, FOXM1 y BIRC5/survivina.
    •TRO y DR según se describe en los criterios RECIST 1.1 e iRECIST.
    •SSP según se describe en los criterios RECIST 1.1 e iRECIST, definida como el intervalo de tiempo desde la fecha de la primera administración del tratamiento del estudio hasta la fecha de progresión (según los criterios RECIST 1.1 o iRECIST) o la muerte por cualquier causa, lo que se produzca antes. Los pacientes que no presenten progresión ni muerte serán objeto de censura estadística en el momento de la última evaluación del tumor.
    •La ST se define como el intervalo de tiempo desde la fecha de la primera administración del tratamiento del estudio hasta la fecha de muerte por cualquier causa. Los pacientes vivos serán objeto de censura estadística en la fecha del último seguimiento documentado.
