Schemi di trattamento e risultati clinici delle combinazioni di Palbociclib in HR+HER2-MBC (PRECIOUS)

9 giugno 2026 aggiornato da: Pfizer

Combinazioni di palbociclib in pazienti con carcinoma mammario metastatico HR+/HER2-: uno studio prospettico non interventistico sui modelli di trattamento e sugli esiti clinici in Africa e Medio Oriente (PRECIOUS)

L'obiettivo di questo studio multicentrico non interventistico è fornire dati osservazionali prospettici su pazienti che iniziano il trattamento con la combinazione di palbociclib per contribuire alla conoscenza della gestione della malattia del carcinoma mammario HR+ HER2 metastatico/localmente avanzato, del suo modello di trattamento, dei risultati clinici e qualità della vita (QoL) nella pratica clinica di routine in Africa e nei paesi del Medio Oriente.

Descrizione dettagliata

I pazienti con BC HR+/HER2- metastatico/localmente avanzato la cui decisione terapeutica con palbociclib è stata presa dal proprio medico curante e che soddisfano i criteri di ammissibilità saranno invitati a partecipare allo studio. Possono essere incluse nello studio le pazienti che iniziano il trattamento con palbociclib più letrozolo/inibitore dell'aromatasi o palbociclib più fulvestrant in linea con le indicazioni autorizzate, come terapia di prima o seconda linea per BC metastatico/localmente avanzato.

Le variabili valutate in questo studio saranno i dati demografici del paziente, le caratteristiche cliniche, le condizioni di comorbilità e i farmaci concomitanti, la storia del trattamento con BC HR+ HER2 localmente avanzato e metastatico, il trattamento con BC in corso, lo stato delle prestazioni (Eastern Cooperative Oncology Group (ECOG), i risultati clinici e QoL. Tutte le valutazioni descritte in questo protocollo vengono eseguite come parte della normale pratica clinica o delle linee guida pratiche standard per la popolazione di pazienti e la specialità degli operatori sanitari nei paesi in cui viene condotto questo studio non interventistico. Tutti i dati raccolti in questo studio hanno lo scopo di catturare i modelli di trattamento e gli esiti del mondo reale per i pazienti con BC HR+/HER2- metastatico/localmente avanzato. Per la raccolta dei dati verrà utilizzato un modulo elettronico di segnalazione dei casi (eCRF). Gli investigatori saranno formati con una visita iniziale in loco alla clinica sul protocollo, sistema di acquisizione elettronica dei dati (EDC) (ad esempio, eCRF), file master del sito dell'investigatore (ISMF), documentazione e qualsiasi processo di studio applicabile. Qualsiasi nuova informazione rilevante per l'esecuzione di questo studio non interventistico (NIS) sarà inoltrata al personale medico durante lo studio. Il monitoraggio remoto dei dati sarà condotto durante la durata dello studio per garantire la segnalazione tempestiva dei dati sulla sicurezza, l'integrità e la coerenza dei dati.
