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 evaluating how well the approved weekly injectable insulin icodec controls blood sugar levels compared to daily injectable basal insulins in adults with type 2 diabetes. This Phase 4 study focuses on people who need to start basal insulin treatment and have had type 2 diabetes for at least 180 days. The goal is to understand the effectiveness of once-weekly insulin icodec against standard daily basal insulins in real-world clinical practice over about 13 months. Participants will receive either insulin icodec once a week or one of the daily basal insulin analogues, such as insulin glargine, insulin detemir, or insulin degludec. Both treatments are given by subcutaneous injection. The choice between weekly or daily insulin is based on current treatment standards for type 2 diabetes. The study lasts approximately 52 weeks, during which participants maintain their assigned insulin regimen. During the study, researchers will monitor changes in participants' blood sugar control using the glycated hemoglobin (HbA1c) test from the start until week 52. Participants will have their HbA1c measured within 90 days before starting the treatment. Safety and any reactions to the insulin will also be tracked. The study aims to assess how well the weekly insulin icodec works compared to daily basal insulins in managing blood sugar over a year.

This research aims to assess how satisfied people with Multiple Sclerosis (MS) are after receiving subcutaneous (under the skin) injections of ocrelizumab over a period of 12 months. The study focuses on participants diagnosed with relapsing-remitting MS (RMS) or primary progressive MS (PPMS) according to 2017 McDonald criteria, who are starting ocrelizumab treatment for the first time. The main goal is to understand participant satisfaction using a special questionnaire designed for subcutaneous therapy administration. Participants will receive ocrelizumab as an injection under the skin, with the exact dosing and schedule determined by their treating physician following local medical guidelines. This observational study does not change standard care but monitors patients throughout their treatment with ocrelizumab. During the study, participants will complete the Therapy Administration Satisfaction Questionnaire for subcutaneous treatment after 12 months to measure their satisfaction. Researchers will also observe and record any relevant clinical information. The total study duration for each participant is 12 months, during which their experience and outcomes with ocrelizumab are carefully tracked.

Researchers are investigating the use of ribociclib combined with standard endocrine therapy as a first-line treatment for women with advanced hormone receptor positive (HR+) and human epidermal growth factor receptor negative (HER2-) breast cancer. This phase IV, open-label, single-arm study aims to evaluate the progression-free survival (PFS) and overall survival (OS) rates at 12 months, along with quality of life, treatment toxicity, and comprehensive biomarker analysis to understand patterns of treatment efficacy and resistance. Participants will receive ribociclib orally at a dose of 600 mg daily for 21 consecutive days followed by 7 days off, in 28-day cycles, combined with standard endocrine therapy according to current guidelines and local practice. The study includes extensive biomarker sampling before, during, and after treatment or at disease progression, including blood, tissue, and immune cell analyses to support translational research. During the trial, patients will attend scheduled visits for monitoring and assessments including survival status, safety evaluations, and quality of life questionnaires. Biomarker samples such as circulating tumor DNA and RNA, serum, plasma, and tumor tissue will be collected to evaluate biological changes. The trial plans to enroll 1000 female patients across 75 sites in Germany, with comprehensive follow-up to track treatment outcomes and long-term safety.

Researchers are evaluating the effects of stopping CDK4/6 inhibitors in women with metastatic hormone receptor-positive, HER2-negative breast cancer who have had long-lasting disease control. This phase II, low-intervention trial aims to assess whether patients can maintain stable disease after discontinuing CDK4/6 inhibitors following at least 12 months of combined treatment with endocrine therapy. The study focuses on long-term disease stabilization and progression-free survival 12 months after randomization. Participants are assigned to either continue or discontinue CDK4/6 inhibitors such as Palbociclib or Abemaciclib while maintaining endocrine therapy. The study is open-label and multicenter, allowing close observation of treatment effects. During the trial, patients will be monitored to see if disease control persists after stopping the CDK4/6 inhibitor treatment. Throughout the study, participants undergo regular assessments including evaluations of disease status and safety monitoring. Researchers will track progression-free survival at 12 months after randomization as the primary outcome. The trial includes detailed monitoring of participants' health and treatment responses to understand the impact of discontinuing CDK4/6 inhibitors in this patient population.

Researchers are investigating whether the medicine vicadrostat, when taken together with empagliflozin, can lower the risk of heart-related problems in adults who have type 2 diabetes, high blood pressure, and cardiovascular disease but no history of heart failure. This study is a Phase III trial that compares the effects of vicadrostat plus empagliflozin to a placebo plus empagliflozin in people with these conditions. Participants are randomly assigned to one of two groups: one group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets that look like vicadrostat along with empagliflozin. All participants take one tablet daily for a period ranging from two and a half years up to four years and three months. Throughout the study, participants continue their usual medications for diabetes, high blood pressure, and cardiovascular disease. During up to 51 months of participation, participants visit the study site regularly where doctors collect health information and blood samples. Researchers track when participants experience cardiovascular events such as heart-related deaths or heart failure events. The study also monitors participants’ overall health and any side effects they may experience to assess the safety and effects of the treatments.

Out-of-hospital cardiac arrest (OHCA) affects 70,000 to 100,000 patients annually in Germany, with more than half caused by cardiac issues. Despite advances in medicine, survival rates with good neurological outcomes remain low. There is a lack of sufficient evidence from randomized trials to guide treatment, making systematic data collection crucial to improving care for OHCA patients. The German Cardiac Arrest Registry (G-CAR) aims to better understand OHCA by recording detailed information on patient demographics, disease progression, and treatment outcomes. This registry collects comprehensive data on the pre-clinical, clinical, and post-clinical treatment phases of patients who suffered OHCA due to cardiac causes. It includes information on clinical examinations, laboratory tests, and treatment methods used during patient care. The focus is on standardized documentation to optimize therapeutic approaches and patient management. Participants are monitored until hospital discharge, typically about two weeks, with the primary outcome being in-hospital mortality. Data collection covers demographic details, psychosocial aspects, clinical course, and various examinations and treatments. This ongoing registry helps researchers measure patient outcomes and safety to enhance future care strategies for OHCA patients.

Researchers are evaluating the effectiveness, safety, and economic benefits of coronary lithotripsy compared to other procedures like cutting or super high pressure balloon angioplasty and ablative methods in treating severely calcified coronary artery lesions. The study focuses on patients with coronary artery disease who have severe calcification in their coronary arteries, aiming to improve the preparation and treatment of these blockages. This is a randomized, multicenter clinical trial assessing these different methods to better understand their benefits in lesion treatment. Participants receive either intravascular lithotripsy (IVL) using balloons with a burst pressure of up to 18 atmospheres or standard non-IVL methods such as special high pressure, super high pressure, cutting balloons, and ablative procedures for treating severely calcified lesions. The trial compares these treatment groups to assess additional benefits of coronary lithotripsy. Treatments are performed during the interventional procedure aimed at opening narrowed coronary arteries. During the study, participants are monitored for major cardiac and cerebrovascular events up to 12 months after randomization. Researchers will collect data on the combined endpoint of these serious events to evaluate the treatments' outcomes. Participants must meet specific eligibility criteria and provide informed consent. The study aims to provide insights into the best treatment approaches for patients with severe coronary artery calcification, with follow-up extending over one year after treatment.

Researchers are investigating the effects of pelacarsen (TQJ230) compared to a placebo in adults with atherosclerotic cardiovascular disease (ASCVD) who have high levels of lipoprotein(a) (Lp(a)) and are also receiving inclisiran treatment for elevated low-density lipoprotein cholesterol (LDL-C). The study is designed as a Phase 3 randomized, double-blind, placebo-controlled, multicenter trial with a parallel group structure, followed by an open-label treatment period. The aim is to assess the efficacy, safety, and tolerability of pelacarsen in this population. Participants will receive pelacarsen or placebo as a solution for subcutaneous injection using prefilled syringes. All participants will be given background treatment with inclisiran, starting with two loading doses spaced three months apart during the run-in period. Afterward, inclisiran will be administered every six months at Month 5 and Month 11. Following the double-blind phase, an open-label treatment period will continue, allowing further evaluation of the treatments. Throughout the study, participants will undergo assessments including measurement of lipoprotein(a) levels, with the primary outcome focusing on change in log-transformed Lp(a) concentration from baseline to six months. Laboratory tests will monitor LDL-C and other relevant markers. Safety and tolerability will be tracked continually, and standard care for cardiovascular risk factors such as hypertension and diabetes will be maintained. The study includes adults aged 18 to 80 years with established ASCVD and elevated lipid levels, ensuring ongoing monitoring and evaluation of treatment effects.
