Number of Participants With TEAE by Severity
Tidsramme: Up to Month 12
|
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 for individuelle deltakerdata (IPD)
Planlegger du å dele individuelle deltakerdata (IPD)?
IPD-planbeskrivelse
CSL vil vurdere forespørsler om å dele individuelle pasientdata (IPD) fra systematiske gjennomgangsgrupper eller godtroende forskere. For informasjon om prosessen og kravene for å sende inn en frivillig forespørsel om datadeling for IPD, vennligst kontakt CSL på clinicaltrials@cslbehring.com.
Gjeldende landsspesifikke personvern og andre lover og forskrifter vil bli vurdert og kan forhindre deling av IPD.
Hvis forespørselen godkjennes og forskeren har utført en passende datadelingsavtale, vil IPD som er riktig anonymisert være tilgjengelig.
IPD-delingstidsramme
Tilgangskriterier for IPD-deling
Forespørsler kan kun fremsettes av systematiske vurderingsgrupper eller godtroende forskere hvis foreslåtte bruk av IPD er ikke-kommersiell og har blitt godkjent av en intern vurderingskomité.
En IPD-forespørsel vil ikke bli vurdert av CSL med mindre det foreslåtte forskningsspørsmålet søker å svare på et betydelig og ukjent medisinsk vitenskapelig eller pasientbehandlingsspørsmål som bestemt av CSLs interne revisjonskomité.
Anmodende part må utføre en passende datadelingsavtale før IPD vil bli gjort tilgjengelig.
