Condition/Disease

Advanced Breast Cancer

Objectives

The primary objective of this trial is to evaluate the efficacy of saruparib (AZD5305) plus camizestrant versus physician-selected CDK4/6i plus ET in patients with BRCA1, BRCA2, or PALB2m, HR-positive, HER2-negative (defined as IHC 0, 1+, 2+/ISH no amplification) advanced breast cancer.

Test Drug

Active Ingredient

Saruparib

Dosage Form

Dosage

60 mg

Endpoints

The efficacy of saruparib (AZD5305) + camizestrant was demonstrated through PFS evaluation, which showed its superiority over the physician's choice of CDK4/6i + ET.
