Talazoparib + Avelumab for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effects of two drugs, talazoparib (a PARP inhibitor) and avelumab (an immunotherapy), for individuals with advanced breast cancer. Participants will initially take talazoparib alone, followed by a combination of talazoparib and avelumab. The study seeks individuals with advanced breast cancer who cannot undergo surgery or radiation and have a condition suitable for biopsy. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment combination.
Do I have to stop taking my current medications for the trial?
The trial does not specify if you need to stop taking your current medications, but it does mention that you should not be using potent P-gp inhibitors within 7 days before starting the trial. It's best to discuss your current medications with the trial team to get specific guidance.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that talazoparib, a treatment for advanced breast cancer, has been studied for its safety. Findings indicate that while side effects may occur, proper care and guidelines can manage them.
For avelumab, studies have demonstrated it is generally safe and well-tolerated, even for patients with extensive cancer treatment histories.
Both treatments have been researched in various studies and can be used safely with proper management. Although risks exist, they are understood and manageable with the right support.12345Why are researchers excited about this trial's treatments?
Researchers are excited about combining Talazoparib and Avelumab for breast cancer treatment because it offers a unique approach compared to standard therapies. Most current treatments target hormone receptors or HER2 proteins, but Talazoparib is a PARP inhibitor that specifically targets cancer cells' DNA repair mechanisms, potentially leading to more effective cancer cell death. Adding Avelumab, an immunotherapy drug, helps the immune system recognize and attack cancer cells more effectively. This innovative combination could enhance treatment efficacy and offer new hope for patients with breast cancer.
What evidence suggests that this trial's treatments could be effective for advanced breast cancer?
Research has shown that talazoparib, when used alone, may help treat advanced breast cancer, with about 57.1% of patients experiencing significant tumor shrinkage. In this trial, participants will initially receive talazoparib as monotherapy. Starting with the second cycle, avelumab will be added to the treatment regimen. Previous studies indicate that the combination of talazoparib and avelumab is safe and effective, benefiting 18.2% of patients with triple-negative breast cancer and 34.8% of patients with hormone receptor-positive breast cancer. These results suggest that this treatment could be promising for advanced breast cancer cases.678910

Are You a Good Fit for This Trial?
This trial is for adults with advanced breast cancer that can't be cured by surgery or radiation, who are in good physical condition (ECOG 0-1), and have a life expectancy over 3 months. They must not have used PARP inhibitors before, no recent severe infections or certain chronic diseases like HIV or hepatitis B, and no history of serious allergic reactions to similar drugs. Women must not be pregnant and should agree to contraception.Inclusion Criteria

Experimental Treatment
Talazoparib (1mg by mouth \[PO\] daily D1-28) will be provided as monotherapy for the first cycle. Starting with cycle 2 and for all subsequent cycles, treatment with avelumab (800 mg intravenously \[IV\] D1 every 2 weeks) will be added to talazoparib.
Talazoparib is already approved in United States, European Union for the following indications:
- Deleterious or suspected deleterious germline BRCA-mutated HER2-negative locally advanced or metastatic breast cancer
- Monotherapy for the treatment of adult patients with germline BRCA1/2 mutations, who have HER2-negative locally advanced or metastatic breast cancer
