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 a treatment approach for early-stage hormone-sensitive, HER-2 negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial compares breast conservation surgery with endocrine therapy alone against breast conservation surgery with both radiation and endocrine therapy. The goal is to see if skipping radiation after lumpectomy is not worse in preventing cancer recurrence in the same breast. Participants will be randomly assigned to one of two groups. One group will receive radiation therapy to the breast plus at least five years of endocrine therapy with drugs such as Tamoxifen, Anastrozole, Letrozole, or Exemestane. The other group will receive endocrine therapy only for at least five years without radiation. Radiation must start within 12 weeks of surgery if assigned. Endocrine therapy dosing and schedule are determined by the treating doctor. During the study, participants will have regular follow-ups up to five years to monitor cancer recurrence in the breast and elsewhere, survival, and breast preservation. Assessments will include clinical exams, imaging like mammograms or MRI, and pathology reviews. The main outcome is time to invasive or noninvasive breast tumor recurrence within five years. Some measures will continue through an average of 15 years, including breast conservation rates. Safety and overall health will be monitored throughout and after treatment.

Researchers are studying premenopausal women with early-stage breast cancer that is estrogen receptor-positive and HER2-negative, focusing on tumors with specific gene recurrence scores. The trial aims to find out if adding chemotherapy to ovarian function suppression plus endocrine therapy improves invasive breast cancer-free survival compared to ovarian function suppression plus endocrine therapy alone. This Phase III trial addresses the need for better treatments in younger women, given their higher risk and past conflicting study results on ovarian suppression and chemotherapy. Participants are randomly assigned to one of two groups one receiving ovarian function suppression combined with an aromatase inhibitor for five years, and the other receiving adjuvant chemotherapy followed by the same ovarian function suppression and aromatase inhibitor regimen. Choices for the aromatase inhibitor and gonadotropin releasing hormone agonist are made by the investigator, with options including drugs such as goserelin, leuprolide, or triptorelin. Endocrine treatment beyond five years is at the investigators discretion, and bilateral oophorectomy may be used instead of ovarian suppression if preferred. During the study, participants are monitored over 11 years from randomization, with measurements including invasive breast cancer-free survival as the primary outcome. Secondary outcomes include disease-free survival, overall survival, recurrence intervals, menopausal symptoms, and pain during aromatase inhibitor therapy. Safety and treatment effects are assessed through regular evaluations, and participants continue to be followed long term to understand the impact of treatments on their breast cancer outcomes.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.

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.

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.
