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   44309   clinical trials with a EudraCT protocol, of which   7356   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 ).

    E.2.1Main objective of the trial
    Open-Label Dose Escalation:
    Evaluate the safety and tolerability of weekly IV doses of 100 and 200 mg/kg of eteplirsen.

    Double-blind - Dose Finding Part:
    Evaluate the PK, PD (exon skipping

    Double-Blind - Dose Comparison:
    Comparison of a selected high dose of eteplirsen with 30 mg/kg IV weekly to investigate the effect of a selected high dose of eteplirsen (100 mg/kg or 200 mg/kg) as compared with 30 mg/kg, administered weekly IV, on motor function in ambulant Duchenne muscular dystrophy (DMD) patients with confirmed deletion genotypes amenable to exon 51 skipping
    Escalation della dose in aperto:

    Doppio cieco - Determinazione della dose:
    Valutare le caratteristiche di PK, PD (quantificazione dello skipping dell’esone), sicurezza e tollerabilità di dosi superiori a 30 mg/kg di eteplirsen, per selezionare la dose singola più elevata di eteplirsen da utilizzare per il confronto delle dosi.

    Doppio cieco - Confronto delle dosi:
    Confronto di una dose elevata selezionata di eteplirsen con 30 mg/kg somministrati settimanalmente per via endovenosa (IV) per valutare l’effetto di una dose elevata selezionata di eteplirsen (100 mg/kg o 200 mg/kg) rispetto alla dose di 30 mg/kg somministrata settimanalmente per via endovenosa (IV), sulla funzione motoria nei pazienti deambulanti con distrofia muscolare di Duchenne (DMD) con genotipi di delezione confermati riconducibili allo skipping dell’esone 51.

    4. Have intact right and left biceps muscles (the preferred biopsy site) or an alternative upper arm muscle group that will allow for sufficiently sized (1 cm3) muscle biopsies to be obtained prior to and on treatment (for patients in the double-blind part of the study).
    5. Have been on a stable dose or dose equivalent of oral corticosteroids for at least 24 weeks prior to randomization, and the dose is expected to remain constant (except for modifications to accommodate changes in weight and stress-related needs as per recently published guidelines throughout the study).
    6. Have stable pulmonary function (forced vital capacity =50% of predicted and no requirement for nocturnal ventilation) that, in the Investigator's opinion, is unlikely to decompensate significantly over the duration of the study.
    7. If sexually active, agree to use a male condom during such activity for the entire duration of the study and for 90 days after the last dose. The sexual partner must also use a medically acceptable form of contraceptive (ie, female oral contraceptives) during this timeframe. Acceptable methods of contraception include combined (estrogen and progesterone containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, or transdermal); progesterone only hormonal contraception associated with inhibition of ovulation (oral, injectable, or implantable); intrauterine device; intra-uterine hormone-releasing system; bilateral tubal occlusion; vasectomized partner; sexual abstinence; or condom in combination with either cap, diaphragm, or sponge with spermicide (double-barrier contraception).
    8. Have (a) parent(s) or legal guardian(s) who is (are) able to understand and comply with all the study requirements.
    9. Is willing to provide informed assent (if applicable) and has (a) parent(s) or legal guardian(s) who is (are) willing to provide written informed consent for the patient to participate in the study.
    Il paziente deve soddisfare tutti i criteri seguenti per poter essere considerato idoneo a partecipare allo studio:
    1. Essere uomo con una diagnosi clinica consolidata di DMD e una mutazione di delezione fuori frame del gene DMD suscettibile allo skipping dell’esone 51 (ad esempio, delezioni degli esoni 45-50, 47-50, 48-50, 49-50, 50, 52 e 52-63).
    2. Avere un’età compresa tra 7 e 13 anni.
    3. Avere percorso una distanza =300 e =450 metri (senza assistenza) nel test del cammino dei 6 minuti (6MWT), durante la visita di screening e durante la visita al basale per la parte di doppio cieco.
    4. Avere i muscoli dei bicipiti destro e sinistro intatti (il sito di biopsia preferenziale) o un gruppo muscolare alternativo del braccio che consenta di ottenere biopsie muscolari di dimensioni sufficienti (1 cm3) prima e dopo il trattamento (per i pazienti nella parte del doppio cieco dello studio).
    5. Avere assunto una dose stabile o un equivalente della dose di corticosteroidi orali per almeno 24 settimane prima della randomizzazione; la dose dovrà rimanere costante (ad eccezione delle modifiche imposte dai cambiamenti di peso e dalle necessità correlate a stress e secondo le linee guida pubblicate di recente, per tutta la durata dello studio)
    6. Avere una funzione polmonare stabile (FVC = 50% del previsto e nessun requisito di ventilazione notturna) con probabilità minime, secondo il parere dello sperimentatore, di decompensazione significativa nel corso dello studio.
