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 how to best recommend chemotherapy for patients with colon cancer after surgery by using the presence or absence of circulating tumor DNA (ctDNA) in the blood. This approach aims to identify microscopic residual tumor cells and may provide better risk prediction for cancer recurrence compared to traditional methods. The trial focuses on patients with Stage IIB, IIC, or III colon cancer who have undergone complete tumor removal. Participants will have their tumor tissue and blood tested centrally using the Signatera assay to determine ctDNA status. Patients without detectable ctDNA may avoid chemotherapy, while those with detectable ctDNA are considered at higher risk and will be randomly assigned to receive different chemotherapy regimens, including mFOLFOX6, CAPOX, or mFOLFIRINOX, given intravenously or orally over periods ranging from 3 to 6 months. The study includes initial screening, treatment, and possible second randomization for patients whose ctDNA status changes during monitoring. During the study, participants will undergo various assessments including blood tests, imaging scans, and performance evaluations to monitor their health and response to therapy. Researchers will track the time to ctDNA positivity and disease-free survival for up to 3 and 5 years, respectively. Safety and treatment effects will be closely observed throughout the study duration, ensuring thorough follow-up and monitoring for all participants.

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 a phase III trial comparing shorter chemo-immunotherapy without anthracycline drugs to the usual chemo-immunotherapy for treating early-stage triple negative breast cancer (TNBC). This study focuses on whether the anthracycline-free treatment combined with pembrolizumab is at least as effective as the standard anthracycline-containing regimen in preventing breast cancer events. The trial also examines various secondary outcomes including pathological response, survival rates, safety, tolerability, patient-reported quality of life measures, and translational objectives related to tumor immune markers. Participants are randomly assigned to one of two treatment groups. The first group receives paclitaxel, carboplatin, and pembrolizumab intravenously followed by doxorubicin, cyclophosphamide, and pembrolizumab before surgery. The second group receives docetaxel, carboplatin, and pembrolizumab intravenously before surgery. After surgery, patients in both groups may continue pembrolizumab treatment. Blood samples may be collected throughout the trial for additional analyses. During the study, participants undergo multiple assessments including imaging, blood tests, and physical exams before starting treatment. Patient-reported outcomes such as fatigue and physical function are collected through questionnaires. Follow-up visits occur every six months for two years, then annually up to five years to monitor breast cancer event-free survival and overall health. Safety and quality of life are continuously evaluated, and banking of physical specimens is performed for future research.

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.
