Researchers are evaluating the retention rates of two treatments, Upadacitinib (UPA) and tumor necrosis factor inhibitors (TNFi), in adults with moderate to severe active rheumatoid arthritis (RA). The study is observational, conducted in Germany, and aims to compare how long patients stay on each treatment under real-world conditions according to local labels and standard care. About 678 participants will be enrolled across approximately 80 sites in Germany. Participants will have been prescribed UPA or TNFi independently of the study, following approved labels and local regulations. The study will observe participants receiving either UPA or TNFi therapy over a period of up to 24 months. Participants will be followed for up to 24 months to assess treatment retention. Researchers will monitor how long participants remain on their prescribed treatment and collect related clinical data. The total study duration, including recruitment and follow-up, is expected to last about 48 months.

Prurigo nodularis (PN) is a skin condition marked by one or more intensely itchy nodules that are symmetrically spread across the skin. The main problem is uncontrollable itching that causes repetitive rubbing and scratching, leading to skin injuries. Although research on PN and its impact has grown recently, the disease remains not well studied. This research observes the long-term effects of dupilumab (Dupixent4) treatment in adults aged 18 and older with moderate-to-severe PN, receiving the drug in routine clinical practice in Germany following standard medical guidelines. Treatment decisions are made independently by the patient and their doctor before joining the study. Participants receive dupilumab through subcutaneous injections as prescribed by their physician. The study is non-interventional, meaning no additional investigational drug is provided. The observation period for each participant can last up to two years, with assessments scheduled at the start, one month after beginning treatment, then every three months during the first year, and every six months during the second year. During the study, researchers collect data on treatment effects, safety, and patient-reported outcomes through regular visits and assessments. They measure outcomes like the percentage of participants with improved skin condition and reduced itching severity at six months. Participants complete questionnaires and undergo evaluations to help track their progress and treatment response throughout the study.

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 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.

Immune thrombocytopenia (ITP) is a rare blood disorder where the immune system causes a shortage of platelets, leading to increased bleeding risk. New treatment options have emerged recently, but clinical studies often focus on specific patient groups. This research collects real-world data from a broad range of ITP patients to better understand the diagnosis, treatment, and outcomes in everyday care. The study also aims to improve personalized therapy and patient results by gathering detailed clinical and biospecimen information. The study involves creating a national registry where clinical data and biospecimens are collected from patients diagnosed with primary or secondary ITP. Data are gathered prospectively at defined points during the disease course, and patients can also be included retrospectively within 12 months of diagnosis if ongoing documentation is available. This includes information about disease factors, treatment types, complications, quality of life, fatigue, and survival over 5 years. Participants will provide written consent and undergo clinical assessments at enrollment and follow-up visits. Researchers will collect epidemiological data such as disease incidence, age and sex distribution, causes, treatment types, and remission status over 5 years. The registry also includes biospecimen collection to support high-quality, standardized research. This ongoing monitoring will help improve knowledge of ITP and support better patient care.

Researchers are conducting a prospective, non-interventional observational study to evaluate the long-term effects of dupilumab treatment in patients aged 6 years and older with atopic dermatitis (AD). The study aims to understand the characteristics of AD patients in Germany who receive dupilumab under everyday conditions, including their medical history, socio-demographic and disease-related features, associated atopic comorbidities and type 2 inflammation diseases, as well as their previous and ongoing AD treatments. The study will also assess therapeutic response rates at Month 6 and long-term efficacy at Months 12 and 24 by measuring disease control with tools such as the Atopic Dermatitis Control Tool (ADCT) and Recap of Atopic Eczema (RECAP). Additionally, the study will observe dosing patterns, reasons for treatment changes, and collect long-term safety data. Participants will receive dupilumab treatment as part of their routine care without any intervention from the study. The observation period for each participant lasts up to 2 years or until dupilumab treatment is discontinued. Visits will be scheduled according to the standard of care, and the study will collect data on variations in dosing regimens, treatment initiation or discontinuation reasons, and concomitant therapies. During the study, participants or their guardians will complete questionnaires to assess signs, symptoms, quality of life, and disease control related to atopic dermatitis. Researchers will monitor outcomes such as the number of patients maintaining controlled disease states between Months 6 and 12, and changes in ADCT and RECAP scores over 52 weeks. Safety data will also be collected throughout the observation period to evaluate the long-term effects of dupilumab in both adult and pediatric patients.
