Official title
Phase II of Neoadjuvant Olaparib in Combination With Pembrolizumab in Patients With Triple Negative Breast Cancer (TNBC) or Hormone Receptor-positive HER2-negative Breast Cancer and Germline Mutations in DNA Damage Repair Genes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will test any good and bad effects of combining the study drugs pembrolizumab and olaparib, given before the standard surgical procedure, to treat TNBC or HR+ HER2- breast cancers. The study drugs could shrink cancer, but they could also cause side effects. The study researchers want to find out whether the study drugs will shrink the cancer by a certain percentage compared with its current size, which may improve the outcome of surgery.
