Pre-Surgery Chemotherapy + Trastuzumab for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a combination of chemotherapy drugs and trastuzumab, a monoclonal antibody, to treat breast cancer before surgery. The goal is to determine how effectively these treatments work together to shrink tumors and enhance surgical outcomes. The trial offers different treatment plans based on specific characteristics of the breast cancer, such as HER2 status, a protein influencing cancer growth. Individuals with stage IIA to IIIC breast cancer who have not yet undergone chemotherapy or surgery for this condition might be suitable candidates. Participants will also assist researchers by providing tissue samples, offering insights into how the treatment affects tumor cells. As an unphased trial, this study allows patients to contribute to groundbreaking research that could improve future breast cancer treatments.
Do I need to stop my current medications for this trial?
The trial requires that you stop taking tamoxifen or other similar medications at least one week before enrolling. The protocol does not specify about other medications, so it's best to discuss with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the treatments in this trial are generally well-tolerated, though they have some known side effects.
The combination of paclitaxel and trastuzumab treats HER2-positive breast cancer. Studies have shown that this combination works well, but it can also cause side effects like tiredness, nausea, and sometimes heart problems.
The FDA has approved paclitaxel alone for treating breast cancer. It's effective but can cause side effects like hair loss and low blood cell counts, increasing the risk of infections.
The combination of doxorubicin and cyclophosphamide is a common chemotherapy treatment for breast cancer. It is effective but can cause side effects like nausea and a decrease in blood cells.
For hormone receptor-positive breast cancer, hormone therapy before surgery, known as neoadjuvant endocrine therapy, is used. Treatments like anastrozole and tamoxifen are generally well-tolerated but can cause symptoms like hot flashes and joint pain.
Overall, these treatments have been used for a long time, so their safety is well understood. Most side effects can be managed with proper care.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for breast cancer because they combine chemotherapy with targeted therapy, offering a potentially more effective approach for different cancer subtypes. Unlike standard treatments, which often rely solely on chemotherapy, the incorporation of Trastuzumab in HER2-positive patients targets specific cancer cell receptors, potentially enhancing treatment efficacy. Additionally, the use of neoadjuvant endocrine therapy for ER-positive, HER2-negative patients introduces hormone therapy before surgery, which could shrink tumors and make surgical procedures less invasive. Overall, this multi-faceted approach aims to improve outcomes by tailoring treatments to the cancer's specific characteristics.
What evidence suggests that this trial's treatments could be effective for breast cancer?
In this trial, participants with early-stage HER2-positive breast cancer will receive a combination of paclitaxel and trastuzumab. Research has shown that using paclitaxel and trastuzumab together is highly effective, with studies finding that 98.7% of patients remain cancer-free for at least three years. Adding trastuzumab to chemotherapy significantly reduces the chances of cancer recurrence and lowers the risk of death.
For participants with HER2-negative breast cancer, the trial includes treatment with paclitaxel, doxorubicin, and cyclophosphamide. This combination has demonstrated good results in stopping cancer cells from growing and spreading, leading to an 85.6% chance of being free from cancer events for five years.
In cases of ER-positive, HER2-negative breast cancer, participants may receive neoadjuvant endocrine therapy (NET) as part of the trial. Research suggests that NET can greatly improve surgical outcomes for these patients and has few side effects.16789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for patients with stage IIA-IIIC breast cancer who haven't had prior chemotherapy, radiation, or definitive surgery for the malignancy. They must have documented hormone receptor status and be medically fit for preoperative chemo and surgery. Prior tamoxifen use is allowed if stopped one week before enrollment.Inclusion Criteria

Treatment groups
Experimental Treatment
Patients with ER-positive, HER2-negative disease may receive neoadjuvant endocrine therapy (NET) with an aromatase inhibitor: (either Anastrozole 1 mg po daily; Letrozole 2.5 mg po daily, Exemestane 25 mg po daily or Tamoxifen 20 mg po daily) for 4-6 months prior to surgery (or longer if clinically indicated). Anastrozole for 6 months is the preferred regimen for NET.
Patients receive Paclitaxel 80 mg/m\^2 IV infusion over 1 hour for 12 weeks and Trastuzumab 8 mg/kg IV loading dose over 90 minutes, then 6 mg/kg IV every three weeks (after Paclitaxel when given concurrently) for a total of 17 doses over 51 weeks. Beginning 2-3 weeks after the last dose of Paclitaxel, patients receive Doxorubicin hydrochloride 60 mg/m\^2 IV over 5-10 minutes and Cyclophosphamide 600 mg/m\^2 IV infusion over 30-60 minutes every 2 weeks for 8 weeks.
Patients receive Paclitaxel 80 mg/m\^2 IV infusion over 1 hour for 12 weeks followed by Doxorubicin hydrochloride and Cyclophosphamide (AC). Patients receive Doxorubicin hydrochloride 60 mg/m\^2 IV over 5-10 minutes and Cyclophosphamide 600 mg/m\^2 IV infusion over 30-60 minutes every 2 weeks for 8 weeks.
Patients receive sequential Doxorubicin hydrochloride and Cyclophosphamide (AC) followed by Paclitaxel. Patients receive Doxorubicin hydrochloride IV over 5-10 minutes and cyclophosphamide IV over 30-60 minutes every 2 weeks for 8 weeks. Patients then receive paclitaxel IV over 1 hour weekly for 12 weeks.
