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   43846   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 No
    E.3Principal inclusion criteria
    1. The subject voluntarily gives informed consent to participate in the study.2.18–75 years of age (inclusive) at Screening (i.e. date of providing written informed consent).3.Women of childbearing potential must practice true abstinence from intercourse when it is in line with their preferred and usual lifestyle, or use two different forms of highly effective contraception for the durationof the study, and for at least 30 days after discontinuing study medication. Medically acceptable forms of effective contraception include:(1) approved hormonal contraceptives,(2) barrier methods used with a spermicide,(3) an intrauterine device (IUD),or (4) partner vasectomy. For WOCBP,a negative urine pregnancy test is required at Screening and Baseline prior to initiating study medication.4.If male, must use a condom during the length of the study, and for at least 48 hours after discontinuing study medication.5. Has a diagnosis of symptomatic idiopathic or heritable PAH, PAH associated with CTD, PAH associated with HIV infection, PAH associated with repaired congenital systemic-to-pulmonary shunt (at least 1 (one) year since repair with respect to the date of providing informed consent)or PAH associated with appetite suppressant or toxin use.6.If known positive for HIV infection, has a CD4 lymphocyte count of at least 200 cells/mm3 assessed at Screening and is receiving current standard of care anti-retroviral or other effective medication for treatment of HIV infection.7.Must have a Baseline 6MWD greater than or equal to 150 meters, in the absence of a concurrent injury, illness (other than PAH or a PAH related condition), or other confounding factor including, but not limited to, use of an aid for ambulation (e.g., use of a cane or walker) or connection to a non-portable machine, that would prevent the accurate assessment of the subject's exercise capacity.8.Must be optimally treated with conventional pulmonary hypertension therapy (e.g., oral vasodilators, oxygen, digoxin, diuretics, anticoagulants as deemed appropriate by the investigator) with no additions, discontinuations, or dose changes for a minimum of 10 days prior to randomization. The exceptions are the discontinuation or dose changes of anticoagulants and / or dose change of diuretics.9.Must have been receiving a PAH approved oral monotherapy at a minimum dose that complies with the approved prescribing information for the product for at least 30 days prior to randomization and must have been receiving a stable dose for at least 10 days prior to randomization.10.Has previously undergone a cardiac catheterization within three years prior to the start of screening and the most recent assessment has documented a mean pulmonary artery pressure (PAPm) of at least 25 mmHg, a pulmonary capillary wedge pressure (PCWP) (or in the event a PCWP cannot be reliably obtained, a left ventricular end diastolic pressure (LVEDP)) less than 15 mmHg, and absence of unrepaired congenital heart disease (other than patent foramen ovale (PFO)). In theevent that a reliable PCWP or LVEDP are unable to be obtained during cardiac catheterization, subjects with clinically normal left heart functionand absence of clinically relevant mitral valve disease on echocardiography are eligible for enrollment.11.The subject has undergone echocardiography with evidence of clinically normal left systolic and diastolic ventricular function and absence of any clinically significant left sided heart disease (e.g. mitral valve disease). Subjects with clinically insignificant left ventricular diastolic dysfunction due to the effects of right ventricular overload (i.e.,right ventricular hypertrophy and/or dilatation) are eligible.12.The subject has a previous ventilation perfusion lung scan, and/or high resolution computerized tomography scan of the chest, and/or pulmonary angiography that are consistent with the diagnosis of PAH (e.g., low probability of pulmonary embolism; absence of major perfusion defects).13.The subject has pulmonary function tests conducted within 6 months before screening or during the Screening period to confirm the following:a. Total lung capacity (TLC) is at least 60% (predicted value) assessed by either whole body plethysmography or helium dilution or nitrogen washout technique. b. Forced expiratory volume at one second (FEV1) of at least 50% (predicted value).14.In the opinion of the Principal Investigator, the subject is able to communicate effectively with study personnel, and is considered reliable, willing and likely to be cooperative with protocol requirements, including attending all study visits.
    1.Il soggetto fornisce volontariamente il consenso informato alla partecipazione allo studio. 2. Età compresa tra 18 e 75 anni (inclusi) allo Screening 3. Le donne in età fertile devono astenersi completamente dai rapporti sessuali, quando ciò sia in linea con il loro stile di vita preferito e abituale, oppure utilizzare due diverse forme di contraccezione altamente efficaci per l'intera durata dello studio e per almeno 30 giorni dopo l'interruzione del farmaco in studio. Forme medicalmente accettabili di contraccezione efficace comprendono: (l) contraccettivi ormonali approvati, (2) metodi barriera utilizzati unitamente a uno spermicida, (3) un dispositivo intrauterino (Intrauterine Device, IUD) o (4) vasectomia del partner. Per le WOCBP è richiesto un test di gravidanza sulle urine con esito negativo allo Screening e al Basale prima di iniziare l'assunzione del farmaco in studio. 4. I soggetti di sesso maschile devono utilizzare un preservativo per l'intera durata dello studio e per almeno 48 ore dopo l'interruzione del farmaco in studio.

Se è stata accertata la positività all'infezione da HIV, il soggetto deve presentare una conta linfocitaria CD4 di almeno 200 cellule/mm3 valutata allo Screening e deve essere attualmente in trattamento con la terapia standard antiretrovirale o altro farmaco efficace per il trattamento dell'infezione da HIV. 7. Deve presentare al Basale una 6MWD pari o superiore a 150 metri in assenza di lesione o malattia concomitante (diversa da PAH o condizione correlata alla PAH) o di altro fattore che potrebbe causare confusione, inclusi, in modo non limitativo, l'uso di ausili per la deambulazione (per es. bastone o stampelle) o collegamento a macchine non portatili, che impedirebbero la valutazione accurata della capacità di esercizio del/la paziente. 8. Deve essere trattato in modo ottimale con terapia convenzionale per l'ipertensione polmonare (per es. vasodilatatori orali, ossigeno, digossina, diuretici, anticoagulanti secondo quanto determinato appropriato a giudizio dello sperimentatore), senza aggiunte, interruzioni o variazioni della dose per almeno 10 giorni prima della randomizzazione. Costituiscono un'eccezione l'interruzione o la modifica della dose di anticoagulanti e/o la modifica della dose di diuretici.
    9. Deve avere ricevuto una monoterapia orale approvata per la PAH alla dose minima che sia conforme con le indicazioni di prescrizione approvate per il prodotto per almeno 30 giorni prima della randomizzazione e deve avere ricevuto un dosaggio stabile per almeno 10 giorni prima della randomizzazione. 10. È precedentemente stato sottoposto a cateterismo cardiaco nei tre anni precedenti l'avvio dello Screening e alla valutazione più recente è stata documentata una pressione arteriosa polmonare media pari ad almeno 25 mmHg, una pressione diincuneamento capillare polmonare o (nel caso in cui una PCWP non possa essere ottenuta in modo affidabile) una pressione telediastolica del ventricolo sinistro inferiore a 15 mmHg e assenza di cardiopatia congenita non riparata .Qualora non sia possibile ottenere un valore affidabile di PCWP o LVEDP durante il cateterismo cardiaco, i soggetti con funzione cardiaca sinistra clinicamente normale e assenza di patologie clinicamente rilevanti della valvola mitrale in base a ecocardiografia vengono ritenuti idonei per l'iscrizione. 11. Il soggetto è stato sottoposto a ecocardiografia con evidenza di funzione ventricolare sistolica e diastolica sinistra clinicamente normale e assenza di cardiopatia del lato sinistro clinicamente significativa (per es. patologia della valvola mitrale). I soggetti con disfunzione diastolica del ventricolo sinistro clinicamente non significativa a causa degli effetti del sovraccarico ventricolare destro (per es. ipertrofia e/o dilatazione del ventricolo destro) sono ritenuti idonei.
    12. Il soggetto dispone di precedente scansione polmonare della perfusione/ventilazione e/o TAC toracica ad alta risoluzione e/o angiografia polmonare che confermano la diagnosi di PAH (per es. bassa probabilità di embolia polmonare, assenza di difetti gravi della perfusione). 13. Il soggetto è stato sottoposto a test della funzione polmonare nei 6 mesi precedenti lo Screening o durante il periodo di Screening per confermare quanto segue: a. Capacità polmonare totale pari ad almeno il 60% valutata tramite pletismografia corporea totale o tecnica di diluizione dell'elio o di washout dell'azoto. b. Volume espiratorio forzato a un secondo

    E.5 End points
    E.5.1Primary end point(s)
    The co-primary hypotheses are that combination therapy with PAH approved oral monotherapy in combination with UT-15C will prolong the time to clinical worsening and/or increase exercise capacity (as measured by the change from Baseline in 6MWD at Week 24) when compared to PAH approved oral monotherapy in combination with placebo in subjects with PAH. To preserve the overall type I error rate at0.05, time to clinical worsening will be tested at the 0.04 level and change in 6MWD will be tested at the 0.01 level.
    Le ipotesi coprimarie prevedono che la terapia combinatoria con la monoterapia orale approvata per la PAH unitamente a UT-15C prolungherà il tempo al peggioramento clinico e/o aumenterà la capacità di esercizio (misurata in base alla variazione della 6MWD alla Settimana 24 rispetto al Basale) rispetto alla monoterapia orale approvata per la PAH unitamente a placebo nei soggetti affetti da PAH. Per conservare il tasso di errore di tipo I complessivo al valore di 0,05, il periodo di tempo prima del peggioramento clinico sarà testato al livello di 0,04 e la variazione della 6MWD sarà testata al livello di 0,01.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Clinical worsening will be assessed continuously from randomisation until the subject's last study visit.6MWTs will be conducted at Screening/Baseline, weeks 4, 8, 12, 24, continued visits every 12 weeks and at study termination. The 6MWT should be conducted 3–6 hours following the previous dose of study medication, to coincide approximately with peak study drug exposure.
    Il peggioramento clinico sarà valutato continuamente dalla randomizzazione fino all'ultima visita di studio del soggetto.
    I test del cammino di 6 minuti (Six Minutes Walking Test, 6MWT) saranno condotti allo Screening/Basale, alle Settimane 4, 8, 12, 24, continuati alle visite successive ogni 12 settimane e alla conclusione dello studio. I test 6MWT dovranno essere condotti 3-6 ore dopo la dose precedente di farmaco in studio, per coincidere approssimativamente con il picco di esposizione al farmaco in studio.
    E.5.2Secondary end point(s)
    -Borg Dyspnea Score
    -Combined 6MWD and Borg Dyspnea Score
    -WHO Functional Class for Pulmonary Hypertension
    -N-terminal proBNP
    -RHC Haemodynamics (optional)
    -Safety Analyses
    L’effetto del trattamento sarà formalmente esaminato sulla base dei tre seguenti endpoint secondari:
    ● NT-pro-BNP alla Settimana 24
    ● Combinazione di 6MWD e punteggio di Borg per la valutazione della dispnea alla Settimana 24
    ● 6MWD alla Settimana 48
    Al fine di controllare il tasso di errore di Tipo 1, il valore p del test NT-pro-BNP alla Settimana 24 sarà esaminato in base al tasso di errore bilaterale di Tipo I pari a 0,05. Se il valore p del test NT-pro-BNP risulta inferiore a 0,05, allora gli altri due endpoint saranno esaminati utilizzando l’approccio di Hochberg:
    Ordine dei valori p dal maggiore al minore come p(1)>p(2). Nello specifico:
    1. Se p(1)< 0,05 rigettare allora entrambe le ipotesi nulle.
    2. Se p(1)> 0,05, ma p(2) < 0,025, rigettare allora l’ipotesi nulla associata a p(2).
    Tutti gli altri endpoint secondari saranno sintetizzati utilizzando statistiche descrittive
    E.5.2.1Timepoint(s) of evaluation of this end point
    The effect of treatment will be formally tested on the following three secondary endpoints:
    ● NT-pro-BNP at Week 24
    ● Combined 6MWD/Borg dyspnea score at Week 24
    ● 6MWD at week 48
    In order to control the Type 1 error rate, the p-value for the NT-pro-BNP at week 24 will be tested at a two-sided Type I error rate of 0.05. If the p-value for NT-pro-BNP is less than 0.05, then the other two endpoints will be tested using the Hochberg approach:
    Orderof the p-values from largest to smallest as p(1)>p(2). Specifically:
    1. If p(1)< 0.05 then reject both null hypotheses.
    2. If p(1)> 0.05, but p(2) < 0.025, then reject the null hypothesis associated with p(2).
    All other secondary endpoints will be summarized using descriptive statistics
    - Il punteggio di Borg per valutare la dispnea sarà valutato dopo ogni test 6MWT – La classificazione funzionale dell.OMS per la PAH sarà valutata al Basale prima di iniziare l’assunzione del farmaco in studio e alle successive visite programmate, nonché ogni volta che il test 6MWT viene effettuato per valutare il peggioramento clinico - Il prelievo dei campioni NT pro-BNP sarà effettuato al Basale (prima di iniziare l.assunzione del farmaco in studio), alla Settimana 12, 24, alla prima Visita successiva e a ciascuna Visita successiva – L’emodinamica (facoltativa) potrà essere condotta al basale e alla settimana 24 - Le analisi di sicurezza saranno condotte allo Screening, al Basale, alle Settimane 4, 8, 12, 24 e in seguito ogni 12 settimane, nonché alla Visita conclusiva
