Resumen

The primary objective of the study is to measure efficacy of saruparib (AZD5305) plus camizestrant compared with physician's choice CDK4/6i plus ET in patients with BRCA1, BRCA2, or PALB2m, HR-positive, HER2-negative (defined as IHC 0, 1+, 2+/ ISH non-amplified) advanced breast cancer

Descripción detallada

Approximately 2,620 participants will be screened to achieve approximately 500 participants randomised to study intervention. Participants will be randomised in a 2:2:1 ratio to one of the following intervention groups: * Arm 1: saruparib (AZD5305) plus camizestrant * Arm 2: Physician's choice CDK4/6i plus physician's choice ET * Arm 3: Physician's choice CDK4/6i plus camizestrant Treatment continues until BICR-confirmed disease progression, unacceptable toxicity occurs, or the participant withdraws consent.
