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   43870   clinical trials with a EudraCT protocol, of which   7289   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.3Principal inclusion criteria
    1. Subject has a confirmed pathogenic or likely pathogenic mutation in the CDKL5 gene and a clinical diagnosis of CDD with epilepsy onset in the first year of life, plus motor and developmental delays.
    2. Subject is male or female, aged 1 to 35 years, inclusive, as of the day of the Screening Visit. Subjects aged 1 to < 2 years will ONLY be permitted to enroll in the trial AFTER the DSMB has determined that it is appropriate to do so based on a planned unblinded interim safety review to be conducted after approximately 40 subjects aged = 2 to 35 years have completed Visit 6.
    3. Subject must have failed to achieve seizure control despite previous or current use of 2 or more AETs.
    4. Subject is currently receiving at least 1 concomitant antiseizure treatment: antiseizure medication (ASM), vagus nerve stimulation (VNS), responsive neurostimulation (RNS), or ketogenic diet (KD). During the trial, rescue medications or interventions for rescue treatment of seizures will not be counted towards the total number of antiseizure treatments established at Baseline.
    5. All medications or interventions for epilepsy (including VNS, RNS, and KD) must be stable prior to screening and are expected to remain stable throughout the study. In order to establish stability at BL, duration of treatment with medications or interventions for epilepsy prior to the Screening visit must be as follows: VNS and RNS: = 6 months duration; ASMs or KD: = 4 weeks duration.
    6. At the Screening Visit, parent/caregiver reports that subject has = 4 countable motor seizures (CMS) per week. CMS include distinct seizures of the generalized tonic-clonic [GTC], bilateral clonic, bilateral tonic, atonic (drop), bilateral tonic/atonic (drop), or focal to bilateral tonicclonic type lasting approximately 3 seconds or longer, to distinguish from short-clustered seizures, spasms, or jerks.
    7. Subject (and/or subject's parent[s]/legal guardian[s]) has provided written informed consent (and assent if applicable).
    8. Subject (and/or subject's parent/caregiver) is willing and able to comply with study requirements (including diary completion, visit schedule, and study drug accountability).
    Per essere idonei a essere arruolati in questo studio, i soggetti devono soddisfare i seguenti criteri di inclusione:
    1. Il soggetto presenta una mutazione patogena confermata o una mutazione presumibilmente patogena nel gene CDKL5 e una diagnosi clinica di CDD con insorgenza di epilessia nel primo anno di vita, in associazione a ritardi motori e di sviluppo.
    2. Il soggetto è di sesso maschile o femminile, di età compresa tra 1 e 35 inclusi il giorno della Visita di screening. I soggetti di età compresa tra 1 e < 2 anni potranno arruolarsi nella sperimentazione SOLO DOPO che il DSMB avrà stabilito che sia appropriato farlo in base a una revisione della sicurezza ad interim non in cieco programmata, da svolgersi dopo che circa 40 soggetti di età compresa tra = 2 e 35 anni avranno completato la Visita 6.
    3. Il soggetto deve non aver raggiunto il controllo delle crisi convulsive nonostante l’uso precedente o concomitante di 2 o più AET.
    4. Il soggetto sta ricevendo al momento almeno 1 trattamento anticonvulsivo concomitante: farmaco anticonvulsivo (ASM), stimolazione del nervo vagale (VNS), neurostimolazione responsiva (RNS) o dieta chetogenica (KD). Durante la sperimentazione, i medicinali di soccorso o gli interventi per il trattamento di soccorso delle crisi convulsive non saranno conteggiati nel numero totale di trattamenti anticonvulsivi al Basale.
    5. Tutti i medicinali o gli interventi per l’epilessia (compresi VNS, RNS e KD) devono essere stabili prima dello screening e si prevede che rimangano stabili per tutto lo studio. Per determinare la stabilità al BL, la durata del trattamento con medicinali o interventi per l’epilessia prima della visita di Screening deve essere la seguente: VNS e RNS: = 6 mesi di durata; ASM o KD: = 4 settimane di durata.
    6. Alla Visita di screening, segnalazione da parte del genitore/caregiver che il soggetto ha = 4 crisi convulsive motorie (CMS) numerabili a settimana. Le CMS comprendono crisi convulsive distinte di tipo generalizzato tonico-clonico (GTC), bilaterale clonico, bilaterale tonico, atonico (caduta), bilaterale tonico/atonico (caduta), o da focale a bilaterale tonico-clonico che durano circa 3 secondi o più a lungo, per distinguerle da crisi convulsive brevi-raggruppate, spasmi o scatti.
    7. Il soggetto (e/o il(i) genitore(i)/tutore(i) legale(i) del soggetto) ha fornito il consenso informato scritto (e l’assenso se pertinente).
    8. Il soggetto (e/o il genitore/caregiver del soggetto) desidera ed è capace di aderire ai requisiti dello studio (compresi la compilazione del diario, il programma delle visite e la contabilità del farmaco in studio).
