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 evaluating the treatment and disease progression in men with recurrent or metastatic prostate cancer through a long-term registry study. The study includes patients with four distinct prostate cancer conditions: biochemical recurrence after surgery or radiation, non-metastatic castration-resistant prostate cancer, metastatic hormone-sensitive prostate cancer, and metastatic castration-resistant prostate cancer. Each group is studied independently during different time periods to better understand their treatment courses and disease outcomes. There is no specific treatment assigned by the study. Instead, patients receive care according to the usual medical practice at their treatment centers. Treatments may vary and are decided by each patient's doctor. Data is collected at routine visits after enrollment, then every 3 or 6 months, and whenever therapy changes. This includes recording treatments, disease status, quality of life questionnaires (FACT-P and EQ-5D-5L), and collection of biomaterial. Participants will be involved in regular follow-up visits where their disease progression and therapy details are documented. The study monitors therapy frequencies and patterns for an average of 7 years. Researchers assess these long-term outcomes along with quality of life and other clinical data to better understand prostate cancer management in real-world settings.

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.
