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 studying the safety and effectiveness of brenipatide, given alongside standard treatment, compared to a placebo with standard treatment, to see if it can delay the return of symptoms in adults with major depressive disorder. This is a Phase 3, randomized, double-blind study involving adult participants aged 18 to 75 years. The trial is designed to assess how long it takes for depression symptoms to relapse after starting the adjunctive treatment. Participants will receive either brenipatide or placebo, both administered by subcutaneous injection, in addition to their stable standard of care medication. The study has three main periods: a screening period lasting about one month, followed by a treatment phase of at least 12 months where participants receive the assigned injections, and finally a follow-up period of roughly two months. The total time in the study can be shorter if symptoms worsen or if a participant withdraws. During the trial, participants will need to attend scheduled visits, self-inject the study drug, maintain study diaries, and complete questionnaires. Researchers will monitor participants closely to determine the time until relapse of major depressive disorder symptoms occurs. Safety and adherence to study procedures will be tracked throughout the trial, with the primary outcome measuring the number of days from randomization until relapse.

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.

This research aims to gather real-world information on using intravascular lithotripsy (IVL) with the Shockwave IVL system to treat calcified lesions in the femoropopliteal and crural arteries of patients with chronic limb-threatening ischemia (CLTI). The main goal is to understand how effective IVL is in helping wounds heal and avoiding amputations. The study also looks at how well the treatment restores blood flow immediately, its safety, and its effect on patients' quality of life. Participants receive treatment with the Shockwave Medical IVL System, a comprehensive device that includes a generator, connector cable, and a single-use catheter with an integrated balloon designed to break up artery calcification. The study is observational and collects data on patients who undergo this treatment for their calcified arterial lesions. During the study, researchers will monitor wound healing and whether participants avoid amputation over 12 months. They will also assess how well the blood vessels open after treatment and track safety and quality of life outcomes. Participants will be followed to collect this information over the course of a year to understand the impacts of IVL treatment for CLTI.

Researchers are collecting data in a registry study focused on adults with newly diagnosed or relapsed acute myeloid leukemia (AML). The study aims to gather detailed epidemiological information such as age, prognostic factors, and subgroup distributions. It also compares AML incidence and age distribution with population-based tumor registry data. Important clinical outcomes like relapse-free survival, time to relapse, cumulative incidence of relapse, and overall survival are being evaluated over a 10-year period. This study does not involve experimental treatments but instead documents current treatment strategies used in AML patients. Data collection occurs at 60 investigator sites across Germany, providing a broad overview of patient characteristics and management. There is no upper age limit, and all adult patients diagnosed according to WHO criteria, including acute promyelocytic leukemia, are eligible. Participants will be followed for up to 10 years, during which epidemiological parameters and survival outcomes will be monitored. Researchers will record relapse events, time until relapse, and survival status to understand long-term outcomes. This extensive follow-up intends to support improved knowledge about AML patient prognoses and treatment impacts over time.

Researchers are conducting a Phase 3 study to compare the pharmacokinetics (PK) and pharmacodynamics (PD) of ABP 692 with Ocrelizumab (both US and EU versions) in people with relapsing-remitting multiple sclerosis (RRMS). The study aims to show similarity between these treatments by measuring how the drugs behave in the body and their effects on suppressing new active brain lesions over 24 weeks using MRI scans. Participants will receive intravenous infusions of either ABP 692, Ocrelizumab (US), or Ocrelizumab (EU). The study design allows comparison between these three groups to assess how the drugs are processed and how well they control disease activity. Infusions are given according to the study schedules, and the effects are monitored over the following weeks. During the study, participants will have regular assessments including brain MRI scans to count new lesions, blood tests to measure drug levels, and neurological evaluations to track disease status. The main outcomes include drug concentration over time and the number of new brain lesions up to week 24. Safety and clinical effects will also be observed throughout the study period, which includes screening and follow-up visits.

Researchers are evaluating the safety and effectiveness of nemtabrutinib (formerly ARQ 531) in adults with various blood cancers including chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Richter's transformation, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and Waldenström's macroglobulinemia (WM). This Phase 2 study is designed to better understand how well nemtabrutinib works and how safe it is for these conditions. The study is conducted in two parts: Part 1 focuses on dose escalation and confirmation to find the recommended Phase 2 dose, while Part 2 involves expanding the study to include eight disease-specific groups. Participants receive nemtabrutinib tablets once daily by mouth. Different cohorts in Part 2 are defined based on specific diagnoses and prior treatments, such as those with relapsed or refractory disease after certain therapies. Each participant will receive treatment according to their cohort's criteria. Participants will be closely monitored throughout the study, with assessments including the number of participants experiencing dose-limiting toxicities and adverse events, response rates according to established lymphoma criteria, and treatment discontinuations due to side effects. The study includes detailed evaluations like biopsies for biomarker analysis, imaging scans, and laboratory tests. Safety and treatment effects will be followed for up to several years, allowing researchers to gather comprehensive data on nemtabrutinib's impact.

Researchers are collecting detailed information on adults diagnosed with Acute Lymphoblastic Leukemia (ALL) and related blood cancers such as other leukemias and certain types of Non-Hodgkin's Lymphoma. The purpose is to gather real-world data on diagnosis, treatments, and outcomes to support ALL research and improve quality of care. This registry includes patients whether or not they are part of other clinical trials. Participants included in this registry are adults aged 18 and older diagnosed with ALL or similar leukemias who are treated according to established ALL treatment protocols. It also includes patients with specific subtypes of Non-Hodgkin's Lymphoma treated according to B-ALL protocols. The study involves collecting clinical data and biological samples over time to understand treatment responses and disease progression. Throughout the study, researchers will monitor participants' health outcomes, including overall survival for up to 10 years. Data collected will cover diagnostics, treatments received, and patient outcomes in routine clinical care. This long-term follow-up aims to provide valuable insights into the effectiveness of current therapies and patient experiences with these blood cancers.
