Researchers are evaluating various approved injectable and oral disease-modifying treatments (DMTs) in patients with relapsing multiple sclerosis (RMS) in Germany. This observational, non-interventional, multicenter, open-label study collects primary data prospectively over up to four years, alongside retrospective data. The study captures medical history, disease duration, laboratory values, disability scores (EDSS), MRI results, and relapse information to provide real-world insights into treatment use and outcomes. Patients receiving routine medical treatment with any approved injectable or selected oral DMTs—including ofatumumab, glatiramer acetate, interferon 21, teriflunomide, dimethyl fumarate, and diroximel fumarate—are enrolled without treatment allocation by the study. Two cohorts are observed: one treated primarily with injectable DMTs and another with injectable or oral DMTs. The core study period lasts about two years, with an optional extension providing an additional two years of observation, totaling up to four years. Follow-up visits and monitoring happen at the investigator's discretion and may include telemedicine. During the study, participants provide data through questionnaires and electronic case report forms. Routine clinical care procedures, such as diagnostic tests and monitoring, continue as usual. Researchers measure the proportion of patients continuing their baseline treatment at 24 months and collect ongoing clinical and imaging data. The study emphasizes real-world treatment patterns, safety, and disease activity over the extended follow-up period.

Researchers are evaluating the clinical utility of serum neurofilament light (sNfL) as a prognostic marker for disease activity in patients with relapsing multiple sclerosis (MS). This prospective, multicenter, observational, non-interventional study in Germany aims to understand how sNfL values can influence patient management and treatment decisions. The study focuses on patients treated with category 1 disease-modifying therapies (DMTs) who have incorporated sNfL testing into their care. Participants will either continue their current category 1 DMT, which includes therapies such as dimethylfumarate, glatiramer acetate, interferon beta, and teriflunomide, or switch to ofatumumab based on their physician’s clinical judgment. There is no treatment allocation by the study itself. Data collection will cover up to 24 months, and the frequency of visits and assessments will follow routine clinical practice without a fixed protocol. During the study, baseline and follow-up data will be gathered according to standard care recommendations, including clinical evaluations and sNfL measurements. Researchers will monitor the proportion of patients with high sNfL levels over time to assess disease activity. The observational period is flexible and guided by the treating physician, with no additional diagnostic or monitoring procedures beyond standard care. Participants will be followed for up to two years to better understand how sNfL influences treatment management in relapsing MS.

Researchers are evaluating the real-world effectiveness, safety, and tolerability of ribociclib combined with an aromatase inhibitor, with or without luteinizing hormone-releasing hormone (LHRH) therapy, for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. The study also compares data from patients treated with abemaciclib plus endocrine therapy with or without LHRH, and those receiving endocrine monotherapy with or without LHRH. This observational study aims to understand treatment decisions and clinical use of ribociclib after its approval, collecting socio-economic data, quality of life, and patient compliance information. Participants receive treatment based on their physician's clinical judgment without study-assigned interventions. The treatments observed include ribociclib with an aromatase inhibitor LHRH, abemaciclib with endocrine therapy LHRH, or endocrine monotherapy LHRH. The study is conducted in various breast cancer centers and gynecological practices in Germany and Austria to represent local healthcare settings. Participants undergo assessments to monitor treatment effectiveness, safety, quality of life, and adherence to therapy over time. Data collected include clinical outcomes, adverse events, socio-economic status, and patient-reported compliance. The primary outcome measured is invasive disease-free survival over 36 months. This information will help inform clinical decision-making and improve outcomes for patients with early breast cancer in routine practice.

Researchers are investigating the use of elacestrant compared to standard endocrine therapy in patients with estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer who have a relapse detected by circulating tumor DNA (ctDNA). This international, multi-center, randomized, open-label phase III trial aims to determine if elacestrant offers a benefit over current endocrine treatments in this group of patients without distant metastases. The study includes a lengthy ctDNA screening phase to identify eligible participants and monitor their disease status over time. The study begins with a ctDNA screening phase, where patients receive standard adjuvant endocrine therapy such as tamoxifen, letrozole, anastrozole, or exemestane, and have blood collected every six months for ctDNA testing until about 5.7 years after enrollment ends. Those who test positive for ctDNA and show no distant metastasis on imaging will be randomized within four weeks to continue their current endocrine therapy or switch to elacestrant taken orally at 400 mg daily. Treatment duration varies based on prior endocrine therapy exposure, ranging from two to seven years. After treatment, further care is at the physician's discretion. Participants will have frequent follow-up visits with ctDNA testing at weeks 4 and 16 post-randomization and every 16 weeks thereafter for up to three years. Imaging studies including mammograms, bone scans, and CT scans will be conducted regularly to monitor for distant metastases or new cancers. The main outcome measured is distant metastasis-free survival, assessed up to 6.25 years following the first patient enrollment. The study ends when all patients complete their visits or discontinue for reasons such as withdrawal, loss to follow-up, or death, and data is fully analyzed and finalized.

Researchers are evaluating the patient-reported outcomes, real-world efficacy, and safety of trastuzumab deruxtecan (T-DXd) in patients with HER2-positive, HER2-low, or HER2-ultralow unresectable or metastatic breast cancer receiving treatment according to the approved product guidelines in routine clinical practice in Germany. This prospective, non-interventional, multicenter study includes approximately 800 patients divided equally into HER2-positive and HER2-low/ultralow groups. Patients will also be informed about the use of a digital healthcare application (DiGA). Eligible patients must be receiving T-DXd as part of their routine care, with all diagnostic tests and treatment visits determined by their treating physicians and not by the study protocol. The study observes patients treated with T-DXd in line with the applicable summary of product characteristics. Treatment decisions, including visit frequency and procedures, follow standard clinical practice rather than study-mandated schedules. Participants will be followed to monitor the time from the first dose of T-DXd until the start of the next treatment or death, assessed for up to 60 months. Data collection will include patient-reported outcomes, safety information, and real-world clinical data. The study aims to gather comprehensive information on treatment effects and patient experiences during routine care without altering their treatment plan.

Researchers are evaluating the effectiveness and safety of sacituzumab govitecan-hziy (SG) combined with pembrolizumab compared to the treatment chosen by a doctor, which may be pembrolizumab alone or pembrolizumab with capecitabine. This study focuses on patients with triple negative breast cancer who still have invasive cancer remaining after surgery and pre-surgical treatment. The study is a phase 3, randomized, open-label trial designed to assess outcomes in this patient group. Participants receive sacituzumab govitecan-hziy and pembrolizumab through intravenous infusion as the experimental treatment. The comparison group receives the physician's choice of treatment, which involves either pembrolizumab alone intravenously or pembrolizumab combined with oral capecitabine tablets. Both treatment options follow surgery and prior therapy, targeting residual invasive disease. Throughout the study, participants are monitored up to 60 months to measure invasive disease-free survival, which indicates the time without cancer recurrence or progression. Researchers will track treatment safety and effectiveness through regular assessments. The study involves tissue sample submissions from before and after neoadjuvant therapy and surgery, performance status evaluations, organ function tests, and recovery status from surgery and radiotherapy.
