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 two digital mindfulness-based interventions to improve mental health and well-being in younger breast cancer survivors who have elevated depressive symptoms. This phase III randomized trial focuses on women diagnosed at or before age 50, who completed primary cancer treatments at least six months earlier. The study aims to compare the effectiveness of live instructor-led sessions via Zoom and a self-paced app-based program, exploring which approach best supports psychological health in this population. Participants will be assigned to one of three groups the live online mindfulness sessions MAPs LO conducted weekly for 6 weeks via Zoom, the MAPs App delivering the same content in shorter sessions over 6 weeks, or a meditation-only control group accessing guided audio meditations. Both English and Spanish speakers can participate in the live online and meditation groups, while the app is only available in English. Tablets and internet hotspots are provided if needed. All groups have access to the UCLA MARC mindfulness meditation app throughout the 6-month follow-up. During the study, participants will attend weekly sessions for the live group or engage with app content at home, with usage tracked to measure intervention dose. Researchers will assess depressive symptoms shortly after the intervention and again up to 6 months later, along with fatigue symptoms. They will also investigate factors influencing intervention effects, such as baseline distress and social determinants, and evaluate the cost-effectiveness of the programs. The total study duration includes a 6-week intervention period plus follow-up assessments out to 6 months.

This trial evaluates whether a shorter duration of HER2-targeted therapy is as effective as the standard length for treating early-stage HER2-positive breast cancer in patients who had a complete response after preoperative chemotherapy with trastuzumab. The study focuses on comparing 6 months versus 12 months of combined neoadjuvant and adjuvant HER2 blockade and also assesses quality of life and safety outcomes. The trial aims to determine if shorter treatment can maintain similar recurrence-free survival and reduce side effects. Participants are randomly assigned to receive trastuzumab and possibly pertuzumab either intravenously or subcutaneously every 21 days. One group receives treatment for up to 17 cycles about 12 months, while the other group receives treatment for up to 9 cycles about 6 months, as long as no disease progression or unacceptable toxicity occurs. Throughout the trial, patients undergo heart function tests echocardiography or MUGA and breast imaging mammography, ultrasound, or MRI. Optional blood and tissue samples may be collected for additional studies. Participants are followed for recurrence and survival for up to 10 years after treatment begins, with check-ins every 6 months for the first 5 years and then yearly afterward. The study measures recurrence-free survival, overall survival, local and distant cancer recurrence, and patient-reported quality of life using specific questionnaires. It also monitors serious side effects and symptoms like diarrhea, fatigue, and rash. This comprehensive follow-up helps evaluate long-term outcomes and treatment impact.
