Behandlungsmuster und klinische Ergebnisse von Palbociclib-Kombinationen bei HR+HER2-MBC (PRECIOUS)

9. Juni 2026 aktualisiert von: Pfizer

Palbociclib-Kombinationen bei Patientinnen mit HR+/HER2- metastasiertem Brustkrebs: Eine nicht-interventionelle prospektive Studie zu Behandlungsmustern und klinischen Ergebnissen in Afrika, Naher Osten (PRECIOUS)

Das Ziel dieser nicht-interventionellen multizentrischen Studie ist es, prospektive Beobachtungsdaten zu Patienten zu liefern, die eine Behandlung mit einer Palbociclib-Kombination beginnen, um zum Wissen über das Management von HR+ HER2-metastasiertem/lokal fortgeschrittenem Brustkrebs (BC), seinem Behandlungsmuster und den klinischen Ergebnissen beizutragen und Lebensqualität (QoL) in der klinischen Routinepraxis in Afrika und den Ländern des Nahen Ostens.

Detaillierte Beschreibung

Patienten mit HR+/HER2-metastasiertem/lokal fortgeschrittenem BC, deren Behandlungsentscheidung mit Palbociclib von ihrem behandelnden Arzt getroffen wurde und die die Eignungskriterien erfüllen, werden zur Teilnahme an der Studie eingeladen. Patienten, die eine Behandlung mit Palbociclib plus Letrozol/Aromatasehemmer oder Palbociclib plus Fulvestrant in Übereinstimmung mit der/den zugelassenen Indikation(en) als Erst- oder Zweitlinientherapie für metastasiertes/lokal fortgeschrittenes BC bei der Einschreibung beginnen, können in die Studie aufgenommen werden.

Die in dieser Studie bewerteten Variablen sind demografische Daten des Patienten, klinische Merkmale, komorbide Erkrankungen und begleitende Medikationen, HR+ HER2-lokal fortgeschrittene und metastasierte BC-Behandlungsgeschichte, aktuelle BC-Behandlung, Leistungsstatus (Eastern Cooperative Oncology Group (ECOG), klinische Ergebnisse und QoL. Alle in diesem Protokoll beschriebenen Bewertungen werden im Rahmen der normalen klinischen Praxis oder der Standardpraxisrichtlinien für die Patientenpopulation und das Fachgebiet des Gesundheitsdienstleisters in den Ländern durchgeführt, in denen diese nicht-interventionelle Studie durchgeführt wird. Alle in dieser Studie gesammelten Daten sollen die realen Behandlungsmuster und Ergebnisse für Patienten mit HR+/HER2-metastasiertem/lokal fortgeschrittenem BC erfassen. Für die Datenerhebung wird ein elektronisches Fallberichtsformular (eCRF) verwendet. Die Prüfärzte werden bei einem ersten Vor-Ort-Besuch in der Klinik über das Protokoll, das elektronische Datenerfassungssystem (EDC) (d. h. eCRF), die Stammdatei des Prüfarztes (ISMF), die Dokumentation und alle anwendbaren Studienprozesse geschult. Alle neuen Informationen, die für die Durchführung dieser nicht-interventionellen Studie (NIS) relevant sind, werden während der Studie an das medizinische Personal weitergeleitet. Während der Laufzeit der Studie wird eine Fernüberwachung der Daten durchgeführt, um eine zeitnahe Berichterstattung über Sicherheitsdaten, Datenintegrität und -konsistenz zu gewährleisten.

EORTC QLQ-30 included five functional scales (physical functioning, role, emotional, cognitive and social functioning), nine symptom scales (fatigue, nausea or vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties, and a global health status scale (GHS). The GHS/QoL scale ranged from 1=very poor to 7=excellent. All other items ranged from 1=not at all to 4=very much.
