Researchers are evaluating the real-world effectiveness, safety, and patient compliance of ribociclib combined with an aromatase inhibitor for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. This observational study also compares ribociclib treatment with abemaciclib plus endocrine therapy and endocrine therapy alone, aiming to better understand treatment decisions and clinical adoption in routine practice. The study is conducted across breast centers and gynecological practices to represent typical healthcare settings. Participants receive treatment based on their physicians clinical judgment without randomization or intervention assignment. The study collects data from patients treated with ribociclib plus aromatase inhibitor with or without luteinizing hormone-releasing hormone LHRH, abemaciclib plus endocrine therapy with or without LHRH, or endocrine therapy alone with or without LHRH. Baseline data and follow-up information on adverse events, quality of life, treatment adherence, and socio-economic factors are gathered over time. During the study, participants undergo assessments including evaluation of invasive disease-free survival up to 36 months, quality of life questionnaires, medication adherence reports, and monitoring of adverse events and treatment changes. Data on reasons for treatment decisions, patient perceptions, and healthcare provider involvement are also collected. The study duration extends up to 39 months to provide a comprehensive overview of treatment impact and patient experience in real-world clinical settings.

Researchers are studying patients with hormone receptor-positive, HER2-negative locally advanced or metastatic breast cancer who have gBRCA12 mutations. This study aims to evaluate whether adding elacestrant, a new oral estrogen receptor blocker, to the standard olaparib treatment can improve progression-free survival compared to olaparib alone. This is a phase II, multi-center, randomized, open-label study with patients assigned in a 21 ratio to two different treatment groups. Participants randomized to Arm A will receive 600 mg of olaparib daily plus 400 mg of elacestrant daily, while those in Arm B will receive 600 mg of olaparib daily alone. Treatment will continue until disease progression, unacceptable side effects, patient withdrawal, or the study ends. Pre- and perimenopausal women, as well as men, will also receive a GnRH analogue at least two weeks before treatment starts. Dose modifications are provided for managing specific side effects. During the study, blood tests will be done at the start of each treatment cycle, and imaging scans along with quality of life assessments will be performed every three months or if disease progression is suspected. Researchers will measure progression-free survival, overall survival, treatment failure times, response rates, clinical benefit, adverse events, and treatment compliance. Participants may remain in the study for up to 48 months, with an average treatment duration of about 12 months per patient.

This research investigates GLSI-100 immunotherapy in people with HER2neu positive breast cancer who are at high risk for their cancer returning. It focuses on participants who have completed both neoadjuvant and postoperative adjuvant standard treatments. The study is Phase 3, randomized, double-blinded, and placebo-controlled, involving subjects who are HLA-A*02 positive as well as an open-label group of non-HLA-A*02 positive subjects. The goal is to evaluate the treatments impact on invasive breast cancer-free survival over a median follow-up of 4 years. Participants receive 6 primary immunization injections of GLSI-100 or placebo intradermally once a month for the first 6 months, followed by 5 booster injections spaced 6 months apart, totaling 11 injections over 3 years. There are three groups one receiving placebo 0.9% normal saline, one receiving GLSI-100 immunotherapy in HLA-A*02 positive subjects, and an open-label arm for non-HLA-A*02 positive subjects receiving GLSI-100 under the same schedule. During the study, participants undergo regular monitoring and assessments including invasive disease-free survival, distant disease-free survival, overall survival, and quality of life questionnaires at baseline and up to 36 months. Researchers track safety and treatment effects over a median 4-year follow-up. The study continues until December 2031, aiming to provide comprehensive data on long-term outcomes and quality of life for participants receiving these treatments.

Researchers are studying patients with breast cancer, focusing on those with metastatic disease who typically have the poorest outlook. The trial aims to improve treatment decisions and quality of care by analyzing tumor characteristics. Although national guidelines recommend molecular reassessment of metastatic tumors, biopsies are rare due to invasiveness, so the study explores blood-based methods to assess tumor features and their relation to treatment outcomes and health economics. The study involves two groups about 3,500 patients with locally advanced or metastatic breast cancer receiving any line of treatment, and approximately 10,000 patients with early breast cancer undergoing neoadjuvant or adjuvant therapy regardless of regimen. Blood samples will be collected during routine blood draws to analyze tumor molecular characteristics and biomarkers for progression and survival. Participants will be followed with assessments including quality of life, therapy adherence, depression factors, and adverse events at study entry and regularly up to 60 months. The study will measure progression-free survival in metastatic breast cancer and disease-free survival in early breast cancer, along with overall survival and health economic outcomes. Results of molecular testing will be shared with patients at study end, providing comprehensive data to support improved breast cancer care.
