Severity of AE was assessed by the investigator and categorized as mild, moderate and severe where: Mild: AE that is usually transient and may require only minimal treatment or therapeutic intervention. The event does not generally interfere with usual activities of daily living. Moderate: AE that is usually alleviated with additional specific therapeutic intervention. The event interferes with usual activities of daily living, causing discomfort but poses no significant or permanent risk of harm to the research participant. Severe: AE that interrupts usual activities of daily living, significantly affects clinical status, or may require intensive therapeutic intervention. |

Plan pour les données individuelles des participants (IPD)
Prévoyez-vous de partager les données individuelles des participants (DPI) ?
Description du régime IPD
CSL examinera les demandes de partage de données individuelles sur les patients (DPI) provenant de groupes d'examen systématique ou de chercheurs de bonne foi. Pour plus d'informations sur le processus et les exigences de soumission d'une demande de partage volontaire de données pour IPD, veuillez contacter CSL à clinicaltrials@cslbehring.com.
La confidentialité spécifique au pays applicable et d'autres lois et réglementations seront prises en compte et peuvent empêcher le partage d'IPD.
Si la demande est approuvée et que le chercheur a signé un accord de partage de données approprié, l'IPD qui a été anonymisé de manière appropriée sera disponible.
Délai de partage IPD
Critères d'accès au partage IPD
Les demandes ne peuvent être faites que par des groupes d'examen systématique ou des chercheurs de bonne foi dont l'utilisation proposée de l'IPD est de nature non commerciale et a été approuvée par un comité d'examen interne.
Une demande d'IPD ne sera pas considérée par CSL à moins que la question de recherche proposée ne cherche à répondre à une question importante et inconnue sur les sciences médicales ou sur les soins aux patients, telle que déterminée par le comité d'examen interne de CSL.
La partie requérante doit signer un accord de partage de données approprié avant que l'IPD ne soit disponible.
