Disease category: Breast Cancer

Brief description of trial (Data source: BASEC)

Diese Studie wird weltweit mit ca. 1150 Patientinnen und Patienten durchgeführt und untersucht die Wirksamkeit von Ipatasertib in Kombination mit Atezolizumab und Paclitaxel gegen metastasierten TNBC. Die Behandlungskohorte wird anhand desTumors zugeteilt: es wird zwischen PD L1 positiven und PD L1 nicht-positiven Tumoren unterschieden. Innerhalb der Kohorten wird dann per Zufall über die Behandlungsgruppe (Behandlungsarm) entschieden. Die gesamte Studie dauert ca. 6 Jahre.

Health conditions investigated(Data source: BASEC)

Dreifach negativer Brustkrebs (triple-negative breast cancer (TNBC))

Frauen oder Männer mit lokal fortgeschrittenem, inoperablem oder metastasierendem, dreifach-negativem Adenokarzinom der Brust, die in diesem Setting keine vorherige systemische Chemotherapie erhalten haben, können für diese Studie in Frage kommen. Bei Patienten mit BRCA-assoziiertem Tumor sollte eine platinhaltige Chemotherapie als potenziell bevorzugte Behandlungsoption in Betracht gezogen werden, um festzustellen, ob diese Studie für diese Patienten geeignet sein könnte. Die Patienten können eine vorherige Chemotherapie im neoadjuvanten oder adjuvanten Setting erhalten haben, wenn die Behandlung mindestens 12 Monate vor der Randomisierung abgeschlossen wurde. Die lokal fortgeschrittene, inoperable Erkrankung darf nicht mit kurativer Absicht reseziert werden können. Die Patienten müssen über ausreichend Tumorgewebe verfügen und alle Aufnahmekriterien erfüllen, um eingeschlossen zu werden.
- Frauen oder Männer, die zum Zeitpunkt der Einwilligung 18 Jahre alt sind.
- Bereitschaft und Fähigkeit, alle studienbezogenen Untersuchungen, einschließlich PRO-Bewertungen, nach Ermessen des Prüfers durchzuführen.
- Messbare Erkrankung nach RECIST v1.1
Zuvor bestrahlte Läsionen können nur dann als messbare Krankheit bewertet werden, wenn die fortschreitende Erkrankung seit der Bestrahlung eindeutig dokumentiert ist.
- Eastern Cooperative Oncology Group (ECOG) Leistungsstatus von 0 oder 1
- Ausreichende hämatologische und Organfunktion innerhalb von 14 Tagen vor der ersten Studienbehandlung
- Patient ist geeignet für eine Paclitaxel-Monotherapie bei unbekanntem oder nicht-positivem PD-L1-Status des Tumors bzw. für Paclitaxel und Atezolizumab bei positivem PD-L1-Status des Tumors.
- Histologisch dokumentiertes dreifach-negatives Adenokarzinom der Brust, das lokal fortgeschritten oder metastasierend ist und nicht mit kurativer Absicht resezierbar ist.
