Cancer Vaccine + Chemotherapy for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the effectiveness of a cancer vaccine called STEMVAC when combined with chemotherapy to treat PD-L1 negative, triple-negative breast cancer that has metastasized. The goal is to determine if this combination can enhance the immune system's ability to recognize and destroy cancer cells. Chemotherapy options in the trial include paclitaxel, docetaxel, cisplatin, carboplatin, doxorubicin, eribulin, and others, which are known to stop or slow cancer cell growth. This trial may suit those with triple-negative breast cancer that is PD-L1 negative, has spread from the original site, and have not received prior cancer immunotherapy for metastatic cancer. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial requires a minimum of 14 days without any systemic therapy or palliative radiotherapy before starting the study treatment. However, treatment with bisphosphonates or denosumab is allowed during the study. It's best to discuss your specific medications with the study team to see if any adjustments are needed.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that STEMVAC, a cancer vaccine, is being tested for safety and effectiveness. Early results from various studies suggest that combining STEMVAC with chemotherapy might be a promising treatment for breast cancer. However, researchers are still gathering more information about STEMVAC's safety.
Research has found the chemotherapy drug eribulin to be safe for use. While patients experience some side effects, they are usually manageable. Eribulin is already approved for treating advanced breast cancer, indicating its safety for this condition.
Overall, both STEMVAC and eribulin show potential in treating breast cancer, but ongoing research is crucial to confirm their safety.12345Why do researchers think this study treatment might be promising?
Researchers are excited about STEMVAC for breast cancer because it introduces a unique approach by combining a cancer vaccine with chemotherapy. Unlike traditional treatments that primarily target cancer cells directly, STEMVAC stimulates the body's immune system to recognize and attack cancer cells, potentially enhancing the overall effectiveness of chemotherapy. This dual strategy not only aims to treat existing tumors but also to prevent recurrence by training the immune system to remain vigilant against cancer cells in the future. This innovative combination offers hope for more durable responses and fewer side effects compared to standard chemotherapy alone.
What evidence suggests that this trial's treatments could be effective for metastatic triple-negative breast cancer?
Research has shown that STEMVAC, a cancer vaccine, might help treat PD-L1 negative metastatic triple-negative breast cancer. It boosts the immune system to find and destroy cancer cells. Early results suggest that combining STEMVAC with chemotherapy could enhance its effectiveness. In this trial, participants will receive a combination of STEMVAC, chemotherapy, and GM-CSF. Past studies have shown that one chemotherapy option, eribulin, helped patients with metastatic breast cancer live longer and reduced or eliminated tumors in about 60% of patients. Together, these treatments offer hope for better outcomes in this challenging form of breast cancer.678910

Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive chemotherapy and STEMVAC vaccine. Chemotherapy regimens vary, and STEMVAC is administered with sargramostim intradermally every 21-28 days, with booster doses at 4 and 7 months after the 3rd priming dose.
Follow-up
Participants are monitored for safety and effectiveness after treatment, with follow-up visits every 6 months for 3 years.
Research Biopsy
Participants may undergo CT or ultrasound-guided biopsy for research purposes during the study.
