Researchers are studying treatments for patients with hormone receptor-positive HR-positive and HER2-negative early-stage breast cancer who are at higher risk of relapse after surgery. This phase II, open-label study focuses on using a biomarker called circulating tumor DNA ctDNA to monitor minimal residual disease. The goal is to identify patients at molecular relapse and evaluate whether treatment at this stage can improve outcomes. The study involves multiple centers and is designed to test different treatment options based on ctDNA results. The study has three phases pre-screening, molecular follow-up ctDNA surveillance, and treatment. After giving consent, about 976 eligible patients will enter the ctDNA surveillance phase where tumor tissue and blood samples are collected to create a personalized mutation panel. Blood samples will be analyzed every three months during the first year and every six months thereafter to detect ctDNA. When ctDNA positivity is confirmed, up to 40 patients will be assigned sequentially to one of four treatment arms continuing standard endocrine therapy ET, giredestrant alone, giredestrant with abemaciclib, or giredestrant with inavolisib. Treatments are taken orally in cycles lasting 28 days and may continue up to five years or until disease recurrence or unacceptable side effects. Male and premenopausal participants receive additional hormone therapy LHRH agonist as needed. Participants will undergo regular blood sample collections during surveillance and treatment to monitor ctDNA levels and correlate changes with treatment response. Safety and side effects will be tracked throughout the treatment phase, which can last up to five years. After stopping treatment, patients enter a follow-up period where survival and new cancer therapies are recorded every three months. The primary outcome is measuring a decrease or clearance of ctDNA three months after starting treatment. Secondary outcomes include various ctDNA changes over time and treatment-related adverse events. Additional treatment arms may be added based on ongoing results.

Researchers are conducting a prospective, multicenter observational study to create a registry for patients with unresectable locally advanced or metastatic breast cancer. This study includes patients diagnosed from January 2016 onwards, either at first diagnosis or after recurrence. Treatment choices are made independently by physicians, and the study does not specify any treatment regimen. The study groups are defined by breast cancer subtypes based on receptor expression, including Luminal A-like, Luminal B-like HER2 negative and positive, HER2-enriched, and Triple Negative subtypes. Since this is an observational study, patients receive standard care as determined by their doctors, and no intervention is assigned by the study. Participants medical records and disease management data will be collected and reviewed over an 8-year period. Researchers will evaluate the distribution of breast cancer subtypes, patient and tumor characteristics, hereditary risk factors, gender differences in disease progression, timing of primary tumor surgery, and biomarker presence in tumor and blood samples. Patients may withdraw consent at any time, and the study aims to follow patients until death or study completion.

Researchers are studying vedolizumab, a medicine designed to reduce inflammation and pain in the digestive system, for children and teenagers with moderate to severe Crohns disease who have not responded well or were intolerant to standard treatments. The main goal is to see if participants can achieve remission, meaning their symptoms improve or disappear and endoscopy shows no inflammation. This phase 3, randomized, double-blind study involves about 120 pediatric participants worldwide. Participants will receive three intravenous infusions of vedolizumab over six weeks during the Induction Period, with doses based on their weight. Those who show a clinical response at Week 14 will be randomly assigned to receive either a high or low dose of vedolizumab every eight weeks up to Week 46 during the Maintenance Period. Dose adjustments may be made if disease worsens, and corticosteroid rescue therapy is allowed once during maintenance. After Week 54, eligible participants may continue treatment in an extension study or enter long-term follow-up. Throughout the study, participants will undergo assessments including clinical evaluations, endoscopies, and laboratory tests to measure disease activity and remission using tools like the Pediatric Crohns Disease Activity Index and Simple Endoscopic Score for Crohns Disease. Safety will be monitored through reports of adverse events and antibody levels against vedolizumab. The total participation can include additional safety visits and up to two years of long-term follow-up after the last dose.

This research aims to collect long-term safety data on vedolizumab in children with ulcerative colitis UC or Crohns disease CD who have previously participated in related parent studies. It involves up to 240 participants worldwide, including those from treatment or observational cohorts, to better understand the effects of vedolizumab in pediatric patients with these conditions. In the treatment cohort, participants receive intravenous vedolizumab at doses based on their weight, continuing the same blinded dose they received in the parent study at Week 46. Doses are given every 8 weeks, with options ranging from 100 mg to 300 mg depending on participant weight. The study duration in this cohort is up to approximately 5 years or until treatment becomes commercially available or the study closes. The observational cohort includes participants who received at least one dose in the parent study but are not continuing treatment they are followed for safety events for up to about 2 years without receiving vedolizumab. Participants attend assessment visits at several time points after their last dose in the parent study to monitor safety, growth, and development. Researchers track adverse events, inflammatory bowel disease-related events, and changes in quality of life scores using IMPACT-III questionnaires every 24 weeks. The study also includes a final safety visit 18 weeks after the last dose in the treatment cohort. Overall participation lasts up to 5 years for treated children and up to 2 years for those in the observational group.

Researchers are conducting a national, multicenter observational study called SOGUG-PRINCIS to collect and analyze data on patients with genitourinary cancers treated with recently approved drugs under routine clinical practice in Spain. This study is both retrospective and prospective, aiming to validate real-world effectiveness of these drugs and support future funding decisions. It will serve as a registry where new subprojects will open whenever new drugs receive authorization. The study follows patients who have started treatment with specific drugs funded by the Spanish National Health System, including darolutamide combined with androgen deprivation therapy and docetaxel for hormone-sensitive prostate cancer, adjuvant nivolumab after surgery for urothelial carcinoma, and enfortumab vedotin for urothelial carcinoma. All treatments follow their approved dosing and administration guidelines and standard clinical practice. Participants progress will be monitored through routine data collection to evaluate outcomes such as progression-free survival at 18 months, relapse-free survival at 24 months, and overall survival at 12 months after starting treatment. Data will be gathered from patients treated at participating centers, with follow-up continuing as per routine care. The study does not intervene in treatment decisions, which are made independently before enrollment.
