Clinical Trials for Breast Cancer

Overcoming PARP Inhibitor Resistance in BRCA Germline Mutation Positive Advanced Breast Cancer

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

HealthScout AI summary: Eligible patients are adult women with HER2-negative, germline BRCA-mutated advanced or metastatic breast cancer previously treated with a PARP inhibitor, randomized to olaparib plus cediranib (a VEGFR 1/2/3 tyrosine kinase inhibitor targeting angiogenesis) or olaparib plus ceralasertib (an ATR kinase inhibitor targeting the DNA damage response pathway). Both regimens are oral and require patients to have measurable disease and good performance status.
