Researchers are evaluating whether adding the immunotherapy drug durvalumab to the usual chemotherapy regimen can improve outcomes for patients with MammaPrint High 2 Risk MP2 stage II-III hormone receptor positive, HER2 negative breast cancer. This phase III trial focuses on comparing breast cancer event-free survival and other measures between patients receiving chemotherapy alone and those receiving chemotherapy with durvalumab. Immunotherapy may help enhance the bodys immune response against cancer, while chemotherapy works to stop tumor growth in various ways. Participants are first tested for MP2 status using MammaPrint on previously collected tissue. Those with MP2 results are randomized into two groups. One group receives paclitaxel intravenously on days 1 and 8 every 14 days for six cycles, followed by doxorubicin and cyclophosphamide intravenously every 14 days for four cycles. The other group receives the same chemotherapy schedule combined with durvalumab given intravenously over 60 minutes on specific cycles. Mammography and optional tumor tissue and blood sample collections occur during the study. During the study, participants undergo assessments including mammography, tumor biopsies, blood tests, and quality-of-life questionnaires. Researchers measure outcomes such as event-free survival, response rates, relapse-free survival, overall survival, treatment side effects, and patient-reported fatigue and physical health. After treatment completion, participants are followed for up to 10 years to monitor long-term outcomes and survival. Specimens are also banked for future research.

Researchers are evaluating whether simply observing patients after surgery is as effective as continuing pembrolizumab treatment in preventing cancer recurrence in people with early-stage triple-negative breast cancer TNBC who had a complete response after receiving chemotherapy plus pembrolizumab before surgery. This Phase III trial aims to determine if stopping pembrolizumab post-surgery can maintain recurrence-free survival while potentially improving quality of life and reducing treatment burden. Participants are randomly assigned to one of two groups after finishing chemotherapy with pembrolizumab and surgery. One group continues pembrolizumab intravenously every 3 or 6 weeks for 27 weeks. The other group undergoes observation without further pembrolizumab for the same period. Throughout the study, patients have tumor biopsies and blood collected, along with imaging such as mammography, breast ultrasound, or MRI during follow-up. Participants will be monitored for recurrence-free survival and overall survival for up to 10 years. The study also assesses adverse events, quality of life, financial impact, and work productivity at about 27 weeks after starting the assigned treatment or observation. Safety and treatment effects are tracked through biopsies, imaging, blood tests, and patient questionnaires during the study and follow-up.

Researchers are evaluating a phase III trial comparing shorter chemotherapy-immunotherapy without anthracycline drugs to the usual chemo-immunotherapy for treating early-stage triple negative breast cancer TNBC. This study aims to see if the shorter treatment works as well as the usual anthracycline-containing treatment. The trial also assesses patient-reported outcomes like fatigue and physical function, as well as safety and survival measures. It involves participants with specific stages of TNBC and includes detailed evaluations of tumor response and immune markers. Participants are randomly assigned to one of two treatment groups. One group receives paclitaxel, carboplatin, and pembrolizumab followed by doxorubicin, cyclophosphamide, and pembrolizumab, then surgery, with possible pembrolizumab after surgery. The other group receives docetaxel, carboplatin, and pembrolizumab prior to surgery, with possible pembrolizumab after surgery. Blood samples may be collected throughout the trial for research purposes. During the study, participants undergo surgery after chemotherapy-immunotherapy. They are followed every six months for two years, then annually up to five years. Assessments include breast cancer event-free survival, pathological response, distant relapse-free survival, overall survival, adverse events, and patient-reported fatigue and physical function. Quality of life and other patient-reported symptoms are also evaluated. Specimens are banked for future research. The total participation may last up to five years from registration.
