Los pacientes deben cumplir todos los criterios que se indican a continuación en la selección para considerarlos idóneos para el estudio: 1. Consentimiento informado firmado del padre/madre o tutor legal. Asentimiento informado firmado del paciente, si lo indican la edad del paciente y las pautas institucionales. 2. Finalización del estudio índice conforme al protocolo del estudio en las 12 semanas previas. |

E.4 | Principal exclusion criteria |
Subjects meeting any of the following criteria are not eligible for the study: 1.Have any new condition or worsening of existing condition which in the opinion of the Investigator would make the subject unsuitable for enrollment, or could interfere with the subject participating in or completing the study 2.Clinically significant abnormalities in hematology or clinical chemistry parameters or ECG, as assessed by the Site Investigator, at the Screening visit that would render the subject unsuitable for participation in the study 3.Subject?s parent or legal guardian is not willing or able to meet standard of care guidelines (including vaccinations and respiratory syncytial virus prophylaxis if available), nor provide nutritional and respiratory support throughout the study 4.Treatment with another investigational agent, biological agent, or device within one month of Screening, or 5 half-lives of study agent, whichever is longer |
Los pacientes que satisfagan cualquiera de los siguientes criterios no reúnen los requisitos del estudio: 1. Tienen una enfermedad nueva o presentan empeoramiento de la afección existente que, según opinión del investigador, haría que el paciente no sea idóneo para inscribirse en el estudio, o podría interferir con la participación del paciente en el estudio o la terminación del mismo. 2. Anomalías clínicamente importantes en los parámetros hematológicos o bioquímicos o ECG, según evalúe el investigador del centro, en la visita de selección que harían que el paciente no sea idóneo para participar en el estudio. 3. El padre/la madre o el tutor legal del paciente no está dispuesto o es incapaz de cumplir las directrices del tratamiento estándar (incluidas las vacunas y el tratamiento profiláctico del virus sincitial respiratorio, si está disponible) o de proporcionar soporte nutricional y respiratorio durante todo el estudio. 4. El tratamiento con otro fármaco en fase de investigación, fármaco biológico o dispositivo en el mes previo a la selección o 5 semividas del fármaco del estudio, el período que sea más largo. |
