Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42567   clinical trials with a EudraCT protocol, of which   7008   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Willing and able to provide written informed consent.
    2. Males and females ≥18 years of age with documented diagnosis of late-onset (defined as first manifestation of signs and symptoms at ≥1 month of age) OTC deficiency, confirmed via enzymatic, biochemical, or molecular testing. This may include identification of a pathogenic mutation, pedigree analysis, liver OTC activity that is <20% of normal activity, or elevated urinary orotate (>20 μmol/mmol creatinine) after an allopurinol challenge test.
    3. Documented history of ≥1 symptomatic hyperammonemia event with ammonia ≥100 μmol/L.
    4. Subject’s OTC deficiency is stable as evidenced by either a) no clinical symptoms of hyperammonemia OR b) an ammonia level <100 μmol/L within the 4 week period preceding the Screening visit.
    5. Subject’s ammonia level on Day 1 (predose) is <100 μmol/L and is within the range of historical ammonia levels obtained when the subject was clinically stable. If the Day 1 (predose) ammonia is >100 μmol/L and the subject is clinically stable, the ammonia level may be repeated and DTX301 administered if the investigator determines that the repeat
    ammonia is within the subject’s normal range. NOTE: If the subject is deemed clinically unstable, dosing will be held and the subject can be rescreened once the subject is determined to be clinically stable.
    6. On stable dose of ammonia scavenger therapy for ≥4 weeks.
    7. Willing to taper or discontinue ammonia scavengers during the study if deemed safe by the investigator.
    8. No known allergic reaction to any component of DTX301.
    9. Willing and able to comply with study procedures and requirements, including periodic inpatient hospitalizations, frequent blood draws, and urine collections over a 24-hour period.
    10. Hematology and coagulation panel results are within the normal range or, if outside the normal range, deemed not clinically significant in the opinion of the investigator.
    11. Males and all females of childbearing potential must be willing to use effective contraception at the time of administration of gene transfer and for the 52 weeks following administration of DTX301 to prevent the potential transmission of the AAV vector. For male subjects, appropriate contraceptive methods include the use of a condom with spermicide. For female subjects, appropriate contraceptive methods include the use of a condom with spermicide plus at least 1 of the following:
    a. Oral contraceptives, other hormonal contraceptives (vaginal products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device;
    b. Use of a diaphragm or cervical/vault cap;
    c. Previous female sterilization (surgical bilateral oophorectomy [with or without hysterectomy] or tubal ligation) at least 6 weeks prior to DTX301 administration. In case of an oophorectomy alone, the reproductive status of the subject must have been confirmed by follow-up hormone level assessment.
    NOTE: Abstinence is an acceptable form of birth control; however, appropriate contraception must be used if the subject becomes sexually active. A condom with spermicide is required to be used by all sexually active vasectomized males in the study in order to prevent potential transmission of the vector via seminal fluid.
    NOTE: Females of childbearing potential are defined as all females physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception for the duration of the study. Females are considered post-menopausal and not of childbearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (eg, age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least 6 weeks prior to enrollment. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of childbearing potential.
    1. Disposición y capacidad para otorgar el consentimiento informado por escrito.
    2. Varones y mujeres mayores de 18 años de edad con diagnóstico documentado de deficiencia de OTC de comienzo tardío (definido como primera manifestación de signos y síntomas a una edad >=1 mes), confirmado mediante análisis enzimático, bioquímico o molecular. Esto puede incluir la identificación de una mutación patógena, análisis genealógico, actividad de la OTC hepática <20 % de la actividad normal, o concentración urinaria de orotato elevada (>20 µmol/mmol de creatinina) después de una prueba de exposición a alopurinol.
    3. Historia clínica documentada de más de 1 episodio sintomático de hiperamonemia con amonio >= 100 µmol/l.
    4. Demostración de que la deficiencia de OTC del sujeto se halla estabilizada basada en: a) ausencia de síntomas clínicos de la hiperamonemia, O b) concentración de amonio <100 µmol/l dentro del periodo de 4 semanas que precede a la visita de selección.
    5. La concentración de amonio del sujeto determinada el día 1 (antes de la dosis) es <100 µmol/l y se sitúa dentro del intervalo de los niveles históricos de amonio medidos estando el sujeto clínicamente estabilizado. Si la concentración de amonio determinada el día 1 (antes de la dosis) es >100 µmol/l y el sujeto se encuentra clínicamente estabilizado, se podrá repetir el análisis del nivel de amonio y administrar DTX301 si el investigador determina que el valor repetido de amonio está dentro del intervalo de normalidad del sujeto. NOTA: Si al sujeto se le considera clínicamente inestable, se aplazará la administración y se podrá repetir el análisis cuando se determine que está clínicamente estabilizado.
    6. El sujeto ha estado recibiendo una dosis estable de fármacos quelantes de amonio durante >=4 semanas.
    7. Disposición para reducir gradualmente o suspender los quelantes de amonio durante el estudio si el investigador lo considera seguro.
    8. Ausencia de reacciones alérgicas conocidas a algún componente del DTX301.

    11. Los varones y las mujeres potencialmente fértiles deben aceptar el uso de métodos anticonceptivos eficaces en el momento de la administración de la transferencia génica y durante las 52 semanas siguientes a la administración de DTX301 para prevenir la posible transmisión del vector del AAV. Para los varones se considera un método anticonceptivo adecuado el uso de preservativo con espermicida. Para las mujeres, se consideran métodos anticonceptivos adecuados el uso de preservativo con espermicida Y al menos uno de los siguientes:
    a. Anticonceptivos orales, otros anticonceptivos hormonales (productos vaginales, parches cutáneos, implantes o productos inyectables) o métodos de barrera como el dispositivo intrauterino;
    b. Uso de diafragma o capuchón cervical;
    c. Esterilización previa en las mujeres (ovariectomía quirúrgica bilateral, con o sin histerectomía, o ligadura de trompas) al menos 6 semanas antes de la administración de DTX301. En caso de ovariectomía sola, únicamente cuando se haya confirmado el estado reproductivo de la mujer mediante la determinación de las concentraciones hormonales.
    NOTA: La abstinencia se considera una forma aceptable de anticoncepción; sin embargo, si el sujeto tiene relaciones sexuales deberá utilizar un método anticonceptivo adecuado. Todos los varones vasectomizados que tengan relaciones sexuales durante el estudio deberán usar preservativo con espermicida para prevenir la posible transmisión del vector a través del líquido seminal.
    NOTA: Se consideran mujeres potencialmente fértiles aquellas que tienen la capacidad fisiológica de quedarse embarazadas, salvo que utilicen métodos anticonceptivos altamente eficaces durante todo el periodo de estudio. Se considera que las mujeres están en la menopausia y no en edad fértil si han tenido 12 meses de amenorrea natural (espontánea) con un perfil clínico apropiado (por ejemplo, edad adecuada, antecedentes de síntomas vasomotores) o se han sometido a ovariectomía quirúrgica bilateral (con o sin histerectomía) o a ligadura de trompas al menos seis semanas antes de la inclusión. Si sólo se ha practicado ovariectomía, se considerará que son fértiles hasta que se confirme su capacidad reproductiva mediante un seguimiento de la concentración hormonal.
