Saruparib (AZD5305) Plus Camizestrant Compared With CDK4/6 Inhibitor Plus Endocrine Therapy or Plus Camizestrant in HR-Positive, HER2-Negative (IHC 0, 1+, 2+/ ISH Non-amplified), BRCA1, BRCA2, or PALB2m Advanced Breast Cancer
Bu çalışma, HR-pozitif, HER2-negatif ilerlemiş meme kanseri (breast cancer) olan hastalarda Saruparib (AZD5305) artı Camizestrant tedavisini, bir CDK4/6 inhibitörü artı endokrin tedavi (veya artı Camizestrant) ile karşılaştırmaktadır. Çalışmaya, tümörde BRCA1, BRCA2 veya PALB2 genlerinde kalıtsal (germline) mutasyon saptanan erişkin hastalar alınmaktadır. Çalışma Faz 3 aşamasında yürütülmekte ve halen katılımcı almaktadır.
