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   43857   clinical trials with a EudraCT protocol, of which   7284   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.

    7. Based on the results of the Hypoparathyroidism Symptom Diary (HPT-SD) administered
    during the first week of the screening period (from Week -3 to Week -2 visits), the
    subject reports at least 2 of the following symptoms that average at least moderate in
    intensity: muscle cramps, muscle spasms or twitching, tingling, numbness, heaviness in
    arms or legs, physical fatigue, or slowed or confused thinking (brain fog). Additionally,
    the sum score of the HPT-SD symptom subscale (items 1-7) measured during the first
    week of the screening period must be ≥6 (see Appendix 3). At least 4 responses must be
    entered for each symptom.
    8. Must be treated with active vitamin D (calcitriol or alfacalcidol) alone or in conjunction
    with calcium supplements.
    If treated with active vitamin D alone, the subject must be taking ≥0.5 μg/day of calcitriol or ≥1.0 μg/day of alfacalcidol. If treated with <0.5 μg/day of calcitriol or <1.0 μg/day of alfacalcidol, the subject must have a history of inability to be successfully managed with a higher active vitamin D dose.
     If the subject is treated with active vitamin D in conjunction with calcium supplements, the subject must be taking ≥0.25 μg/day of calcitriol or ≥0.5 μg of
    alfacalcidol with ≥1000 mg/day of calcium supplement. If the subject is treated with <0.25 μg/day of calcitriol or <0.5 μg of alfacalcidol or <1000 mg/day of calcium supplement, the subject must have a history of inability to be successfully managed
    on higher doses of at least one of these supplements
    9. Has thyroid-stimulating hormone (TSH) results within normal laboratory limits at screening for all subjects not receiving thyroid hormone replacement therapy. For subjects on thyroid hormone replacement therapy, the thyroid hormone dose must have been stable for at least 4 weeks before screening, and serum TSH level must be within the
    central laboratory normal range. A serum TSH level below the lower limit of the normal range but not undetectable in subjects treated with thyroid hormone may be allowed if there is no anticipated need for a change in thyroid hormone dose during the trial.
    10. Has serum 25-hydroxyvitamin D levels ≥50 mmol/L (20 ng/mL) and <1.5 times the upper limit of normal (ULN) for the central laboratory normal range.
    11. Has estimated glomerular filtration rate (eGFR) >30 ml/min/1.73m2.
    12. Prior to randomization, is able to perform daily SC self-injections of study medication (or have a designee perform injection) via a multidose injection pen into the thigh.
    13. Willing to use oral active vitamin D and calcium supplements provided for the study.
    14. With regard to female subjects: women who are postmenopausal (12 consecutive months
    of spontaneous amenorrhea and age more than or equal to 51 years) and women who are surgically sterilized can be enrolled. Women of childbearing potential must have a negative pregnancy test at
    randomization and be willing to comply with any applicable contraceptive requirements of the protocol and pregnancy testing for the duration of the study.
    1. Comprender y tener capacidad y voluntad de cumplir plenamente los procedimientos y las restricciones del estudio.
    2. Tener capacidad de otorgar su consentimiento voluntariamente, mediante un documento de consentimiento informado firmado y fechado, antes de la realización de los procedimientos relacionados con el estudio.
    3. Ser un varón o una mujer de entre 18 y 85 años de edad, ambos inclusive.
    4. En el caso de los sujetos de 25 años o menos, contar con pruebas radiológicas de cierre epifisario en radiografías de la muñeca izquierda y la mano izquierda antes de la aleatorización.
    5. Tener antecedentes de hipoparatiroidismo con inicio 12 meses o más antes de la selección. El diagnóstico de hipoparatiroidismo se establece a partir de una hipocalcemia en un contexto de concentraciones séricas de PTH indebidamente bajas.
    6. Durante la visita de selección de la semana -3, el sujeto informa en la anamnesis de al menos 2 de los siguientes síntomas relacionados con el hipoparatiroidismo que ha presentado en las 2 semanas anteriores a la visita de la semana -3: calambres musculares, fasciculaciones o espasmos musculares, hormigueo, entumecimiento, pesadez de los brazo o las piernas, cansancio físico o pensamiento lento y confuso (mente nublada).
    7. A tenor de los resultados del diario de síntomas de hipoparatiroidismo (HPT-SD) cumplimentado durante la primera semana del periodo de selección (entre la visita de la semana -3 y la de la semana -2), el sujeto informa de al menos 2 de los síntomas siguientes con una intensidad al menos moderada como promedio: calambres musculares, fasciculaciones o espasmos musculares, hormigueo, entumecimiento, pesadez de loa brazos o las piernas, cansancio físico o pensamiento lento y confuso (mente nublada). Además, la suma de las puntuaciones de la subescala de síntomas del HPT-SD (preguntas 1-7) determinadas durante la primera semana del periodo de selección debe ser ≥6 (véase el apéndice 3).

Si toma <0,5 µg/día de calcitriol o <1,0 µg/día de alfacalcidol, el sujeto deberá presentar antecedentes de imposibilidad de tratamiento satisfactorio con dosis mayores de vitamina D activa.
    • Si el sujeto recibe vitamina D activa junto con suplementos de calcio, deberá estar tomando ≥0,25 µg/día de calcitriol o ≥0,5 µg de alfacalcidol con ≥1000 mg/día de suplemento de calcio. Si el sujeto recibe <0,25 µg/día de calcitriol o <0,5 µg de alfacalcidol o <1000 mg/día de suplemento de calcio, deberá presentar antecedentes de imposibilidad de tratamiento satisfactorio con dosis mayores de al menos uno de estos suplementos.
    9. En el caso de los sujetos que no estén recibiendo tratamiento sustitutivo con hormonas tiroideas, presentar concentraciones séricas de hormona estimulante tiroidea (TSH) dentro de los límites normales del laboratorio en la selección.
