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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    2. Evidence of a personally signed and dated informed consent document indicating that the subject or a legally acceptable representative has been informed of all pertinent aspects of the study.If a subject is unable to consent for themselves at Screening, the subject’s legally acceptable representative may provide written consent, in accordance with the country-specific regulations. Those subjects who are unconscious or considered by the Investigator clinically unable to consent at Screening and who are entered into the study by the consent of a legally acceptable representative should provide their own written informed consent for continuing to
    participate in the study as soon as possible on recovery, as applicable in accordance with local regulations.
    3. Subjects must have a confirmed diagnosis of HAP/VAP, or presumed diagnosis of cIAI requiring administration of IV antibacterial treatment
    4. Female subjects of nonchildbearing potential must meet at least 1 of the following
    criteria:
    a. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; status may be confirmed with a serum follicle-stimulating hormone (FSH) level confirming the postmenopausal state;
    b. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
    c. Have medically confirmed ovarian failure.
    5. Female subject of childbearing potential must have a negative serum or urine pregnancy test, with sensitivity of at least 25 mIU/mL.
    6. Subject must be willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

    c. presentare un’insufficienza ovarica clinicamente confermata.
    Nota: tutti gli altri soggetti di sesso femminile (inclusi i soggetti di sesso femminile sottoposti a legatura tubarica) sono considerati soggetti fertili.
    5. Il soggetto di sesso femminile fertile deve presentare un test di gravidanza su siero o urine negativo, con una sensibilità almeno pari a 25 mUI/ml.
    6. Il soggetto deve essere disposto e in grado di rispettare le visite programmate, il piano di trattamento, i test di laboratorio e le altre procedure dello studio.
    E.4Principal exclusion criteria
    1. Subject has an APACHE II score >30.
    2. At Screening the subject is found to have/or strongly suspected to have an infection caused by a Gram-negative species not expected to respond to either ATM-AVI and/or MER (eg, Acinetobacter baumannii), or an infection caused by only Gram-positive species. The subject is allowed to participate in the study if the Investigator considers that the species is a colonizer which does not warrant specific treatment.
    3. Subject has received more than one day (>24 hours) of any systemic antibiotic within the 48 hours prior to randomization. This is inclusive of all doses of any systemic antibiotic initiated in this time period (but not counting overlapping periods of antibiotics), eg, a subject who receives 4 doses of an 8 hourly regimen with the last dose given just before randomization is calculated as 32 hours of prior antibiotic.
    4. Subject has a history of serious allergy such as anaphylaxis, angioedema and bronchospasm, hypersensitivity or any serious reactions to any systemic antibacterial which is allowed per protocol including ATM, carbapenem, monobactam or other ß-lactam antibiotics, AVI, colistimethate or polymixin B, nitroimidazoles or MTZ, vancomycin, linezolid, daptomycin, aminoglycosides (eg, amikacin, gentamicin, tobramycin), or any of the excipients of the respective (investigational) medicinal products to be administered during the study.
    5. Subject is unlikely to respond to up to 14 days of study treatment.
    1. Il soggetto ha un punteggio APACHE II > 30.
    2. Allo Screening il soggetto presenta (o si sospetta fortemente che presenti) un’infezione causata da una specie di patogeni Gram-negativi per la quale non si prevede una risposta ad ATM-AVI e/o MER (ad esempio, Acinetobacter baumannii) o un’infezione causata solo da specie di patogeni Gram-positivi. Il soggetto è autorizzato a partecipare allo studio qualora lo Sperimentatore ritenga che la specie sia una specie colonizzatrice che non richiede un trattamento specifico.
    3. Il soggetto ha ricevuto più di un giorno (> 24 ore) di trattamento con un qualsiasi antibiotico sistemico nelle 48 ore precedenti la randomizzazione. Ciò include tutte le dosi di qualsiasi antibiotico sistemico iniziato in questo intervallo di tempo (senza tuttavia contare i periodi di sovrapposizione di trattamenti antibiotici); ad esempio, per un soggetto che riceva 4 dosi di un antibiotico somministrato a intervalli di 8 ore, con l’ultima dose somministrata poco prima della randomizzazione, la durata calcolata del trattamento antibiotico precedente è di 32 ore.
    L’eccezione a tale criterio è un soggetto che presenti un fallimento del precedente trattamento antibiotico sistemico come evidenziato da un peggioramento documentato dei segni e dei sintomi obiettivi di infezione o da mancanza di miglioramento in almeno un segno o sintomo obiettivo di infezione nonostante un trattamento antibiotico minimo di 48 ore.
    Per i soggetti cIAI che hanno ricevuto meno di un giorno (< 24 ore) di qualsiasi trattamento antibiotico sistemico nelle 48 ore precedenti la randomizzazione, una dose di antibiotico può essere somministrata in fase post-operatoria entro 6 ore dalla procedura chirurgica (definite come 6 ore dal momento della chiusura dell’incisione cutanea o, se la chiusura dell’incisione cutanea non viene eseguita, 6 ore dal momento in cui viene applicata la medicazione della ferita).
    4. Il soggetto presenta un’anamnesi di allergie gravi come anafilassi, angioedema e broncospasmo, ipersensibilità o reazioni gravi a qualsiasi antibatterico sistemico che sia ammesso dal protocollo, compresi ATM, carbapenemi, monobattamici o altri antibiotici betalattamici, AVI, colistimetato o polimixina B, nitroimidazoli o MTZ, vancomicina, linezolid, daptomicina, aminoglicosidi (ad esempio, amikacina, gentamicina, tobramicina) o a uno qualsiasi degli eccipienti dei rispettivi prodotti medicinali (sperimentali) da somministrare durante lo studio.
    5. È improbabile che il soggetto risponda al trattamento dello studio per 14 giorni.
