Researchers are investigating the addition of an immunotherapy drug called durvalumab to standard chemotherapy treatment in patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. This phase III trial aims to compare the effectiveness of usual chemotherapy alone versus chemotherapy combined with durvalumab. Immunotherapy with durvalumab may help the immune system attack cancer cells and prevent tumor growth and spread, while chemotherapy drugs like paclitaxel, doxorubicin, and cyclophosphamide work to stop cancer cells from growing or dividing. Previous studies suggest patients with an MP2 result might respond better to this combined treatment approach. Participants first undergo MammaPrint testing to confirm MP2 status before randomization into two groups. One group receives paclitaxel intravenously on days 1 and 8 every 14 days for 6 cycles, followed by doxorubicin and cyclophosphamide intravenously on day 1 every 14 days for 4 cycles. The other group receives the same chemotherapy schedule plus durvalumab intravenously over 60 minutes on specified cycles during both chemotherapy phases. Mammography is performed during screening, and optional tissue and blood samples are collected for future studies. Throughout the study, participants are monitored through various assessments including imaging, physical exams, laboratory tests, and quality of life questionnaires focusing on fatigue and physical and mental health. Researchers track breast cancer event-free survival and other outcomes such as treatment side effects and response rates. After completing treatment, patients are followed for up to 10 years or until death to evaluate long-term outcomes and safety.

Researchers are evaluating whether breast conservation surgery combined with endocrine therapy can achieve a similar rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation surgery followed by breast radiation and endocrine therapy in patients with Stage I, hormone sensitive, HER2-negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial builds on the established role of radiation after lumpectomy, aiming to identify if radiation can be safely omitted in certain low-risk patients to reduce treatment burden and side effects. Participants receive either breast radiation plus endocrine therapy or endocrine therapy alone. Radiation therapy involves external beam radiation to the whole breast with or without a boost, partial breast irradiation, or accelerated partial breast irradiation, starting within 12 weeks after the last breast surgery. Endocrine therapy is given for a minimum of 5 years, with the specific drug choice and schedule determined by the treating physician. Endocrine therapy may begin before, during, or after radiation therapy, depending on the treatment group. Throughout the study, participants undergo regular assessments including imaging such as mammograms or MRI within six months before enrollment, and clinical evaluations to monitor tumor recurrence. The main outcome measured is the time to invasive or non-invasive ipsilateral breast tumor recurrence over five years. Safety, adherence to therapy, and recovery from surgery are also monitored. The total participation period includes at least five years to evaluate long-term recurrence rates.

Researchers are evaluating if adding adjuvant chemotherapy (ACT) to ovarian function suppression (OFS) plus endocrine therapy (ET) improves invasive breast cancer-free survival (IBCFS) compared to OFS plus ET alone. This Phase III trial focuses on premenopausal women with early-stage breast cancer that is estrogen receptor (ER)-positive, HER2-negative, and has a 21-gene recurrence score between 16-25 for node-negative patients or 0-25 for patients with 1-3 positive nodes. The study addresses the need for better treatment options for younger women diagnosed with this type of breast cancer, as younger age is linked to worse outcomes despite standard therapies. Participants receive one of two treatments: either OFS combined with an aromatase inhibitor (AI) for five years or adjuvant chemotherapy followed by the same OFS plus AI regimen. The specific AI and GnRH agonist used, along with their dosing schedules, are chosen by the investigator, commonly including goserelin, leuprolide, or triptorelin administered monthly or every three months. Bilateral oophorectomy may be used instead of ovarian suppression if preferred. Endocrine therapy beyond five years is at the investigator's discretion. During the trial, participants will be closely monitored for invasive breast cancer-free survival over an 11-year period from randomization. Assessments include clinical evaluations, hormone receptor testing, tumor staging, and genetic recurrence scoring prior to enrollment. Safety and effectiveness data will be collected throughout the study, with particular attention to treatment side effects and long-term outcomes. The trial involves detailed eligibility screening and ongoing follow-up to ensure accurate measurement of the study's primary outcome.

Researchers are evaluating surgical and minimally invasive treatments for lumbar spinal stenosis (LSS) by comparing Medicare patients who received the MILD procedure against those who had interspinous process decompression (IPD). The study focuses on outcomes such as the rate of harms related to the initial procedure and the frequency of additional surgical or minimally invasive interventions within 24 months after treatment. Enrollment includes patients treated from January 1, 2017, onward, with continuation until the sponsor decides to stop. The MILD procedure involves percutaneous image-guided lumbar decompression, performed under fluoroscopy through a dorsal approach to partially remove tissue and bone at the affected spinal level. The control group receives the IPD procedure for LSS. Both groups are monitored for a 24-month period post-index procedure using Medicare claims data to track reoperations and any harms. Participants contribute data through Medicare claims without needing prior enrollment or consent, as the study is exempt from IRB oversight. Researchers collect and analyze information on procedure-related harms and subsequent interventions over two years. This approach allows evaluation of long-term safety and effectiveness outcomes for patients treated with either MILD or IPD.

Researchers are investigating whether observation is as effective as continuing pembrolizumab treatment in patients with early-stage triple-negative breast cancer who achieved a complete response after preoperative chemotherapy combined with pembrolizumab. This phase III trial aims to evaluate recurrence-free survival and quality of life, as well as the value of reducing immunotherapy treatment after surgery in these patients. The study also examines differences in adverse events, overall survival, and financial impacts between treatment approaches. Participants are randomly assigned to one of two groups after completing neoadjuvant chemotherapy with pembrolizumab and surgery. One group receives pembrolizumab intravenously as adjuvant therapy, while the other group undergoes observation without further treatment. Both groups have tumor biopsies and blood samples collected on study and during follow-up. Additional assessments include questionnaires and quality-of-life evaluations. During the study, researchers monitor participants for up to 10 years to measure recurrence-free survival. They assess quality of life using validated tools, track adverse events, and evaluate financial toxicity and work productivity. The study includes tumor tissue analysis, blood sample collection, and patient-reported outcomes to understand the long-term effects and value of treatment de-escalation in breast cancer care.

Researchers are evaluating whether 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy is as effective as 12 months of the same treatment for patients with early-stage HER2-positive breast cancer who have no remaining invasive cancer after preoperative chemotherapy with trastuzumab. This phase III trial focuses on patients who achieved a pathologic complete response (pCR), aiming to assess recurrence-free survival and quality of life outcomes. The study also explores differences in side effects and survival among subgroups based on treatment delivery and hormone receptor status. Participants are randomly assigned to receive either 6 or 12 months of HER2-targeted therapy, including trastuzumab and possibly pertuzumab, administered intravenously or subcutaneously every 21 days. The treatment cycles continue up to 9 or 17 cycles respectively, unless disease progression or unacceptable side effects occur. Throughout the trial, patients undergo regular heart function tests (echocardiography or MUGA), breast imaging (mammography, ultrasound, or MRI), and may optionally provide blood and tissue samples. During the study, patients complete quality of life questionnaires and are monitored for cancer recurrence and side effects. Follow-up visits occur every 6 months for 5 years and then annually up to 10 years after registration. The main outcomes measured include time without cancer recurrence and patient-reported quality of life at 12 months. Safety and long-term effects of the different treatment durations are also assessed.
