There are about 25560 clinical studies being (or have been) conducted in Germany. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will evaluate the efficacy, safety and pharmacokinetics (PK) of VX-864 in PiZZ subjects.
To identify changes on mitral valve morphology and functionality by the application of the PascalTM in MR.
Recently, it has been shown that ketose-inducing dietary interventions slow disease progression in animal models of polycystic kidney disease (PKD), even when the state of ketosis is only induced for a short period of time. The present study aims to investigate the effects of short term ketosis on total kidney volume (TKV) (and other parameters) in 10 ADPKD-patients with rapidly progressive disease.
The study examines, whether the use of the HemoPill Acute ® capsule in case of suspected nonvariceal upper gastrointestinal bleeding can identify cases in which endoscopy can be delayed to 48-96 hours without risk to the patient.
Appendicitis is one of the most common clinical conditions in general surgery. The diagnosis is usually made from clinical examination, imaging (sonography or CT) and laboratory parameters. The laparoscopic appendectomy without drainage has established as the gold standard. Patients usually leave the hospital two days after surgery. In times of corona crisis, patients are unsure to visit the hospital because of fear of infection with SARS-CoV-2. A higher incidence of perforated appendicitis could be an indicator for fear-related delay of going to the hospital. Methods: Investigators performed a retrospective analysis on the incidence of perforated appendicitis in a 10-week interval (mid-March to end of May) of the years 2018, 2019 and 2020 to evaluate possible changes in times of corona crisis. Intraoperative findings, procedures, complications and the length of hospital stay were considered.
The standard procedure in the diagnosis of peripheral round foci is bronchoscopy with transbronchial forceps biopsy (TBB). Despite the simultaneous application of X-ray fluoroscopy, the diagnostic value of this method depends strongly on the size, location and relationship of the foci to the airways as well as their radiological representability. By inserting radial 20 MHz ultrasound probes through the working channel of a flexible bronchoscope into the periphery of the lung, the detection of peripheral foci can be improved. By simultaneously using a virtual bronchoscopy with an ultra-thin bronchoscope, even smaller round foci in the periphery of the lung can be detected. For some years now, tension-resistant cryoprobes have been used for transbronchial biopsy. Here, especially in lesions that can only be reached endoscopically tangentially, advantages have been shown over forceps biopsy. Much larger tissue samples can be obtained without increasing the complication rate. Studies showed that the combination of the EBUS navigation technique with the cryobiopsy procedure is feasible and safe in the endoscopic diagnosis of peripheral lung tumors. This study investigates to what extent the combination of an ultra-thin cryoprobe with an ultra-thin bronchoscope together with the radial EBUS can further improve the diagnosis. This study is a non-randomized pilot study to prove the feasibility of this procedure. The EBUS probe and the bronchoscope are CE certified for this application. The study will be conducted as a monocentric study at the Thorax Clinic at Heidelberg University Hospital. A total of 30 patients with an indication for transbronchial biopsy will be prospectively included. All patients will be examined according to the clinical standard. After a freezing time of 3-7 seconds, the probe together with the bronchoscope will be extracted and the sample will be defrosted in a water-filled sample vial. Up to 4 biopsies will be taken depending on the investigator's assessment. The samples will be collected separately and the order of the biopsies will be recorded. The primary endpoint is the feasibility of the procedure. Secondary endpoints are safety, diagnostic hit rate, biopsy size and quality and success rate depending on the position of the EBUS probe (tangential or central).
This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases. In this study no therapy is being offered.
The main objective of this study is to evaluate the efficacy of danicopan as add-on therapy to a complement component 5 (C5) inhibitor (eculizumab or ravulizumab) in participants with PNH who have clinically evident EVH.
Neoadjuvant systemic therapy (NST) is increasingly recommended for patients with early breast cancer, and the rate of patients with pathological complete remission (pCR) is increasing due to the use of modern chemotherapy regimens and targeted therapies, especially in patients with human epidermal growth factor receptor 2 positive (HER2+) breast cancer and triple negative breast cancer (TNBC). It is therefore important to mark a lesion (with e.g. clip) before the start of NST in order to safely identify and localize a clip and (former) tumor bed after completion of NST. Reliable sonographic detection of the clip would be preferred to mammography-guided detection and marking. In addition to avoiding radiation exposure by mammography and reducing time, personnel and financial expenditure, ultrasound-guided wire marking of the clip is less painful for the patient than stereotactic wire marking. The present prospective registry study aims to evaluate how often the intramammary Tumark® Vision clip can be detected by ultrasound after completion of NST in patients with TNBC and HER2+ breast cancer and thus, in the case of pCR, how often the elaborate clipping with mammographic (stereotactic) guidance can be avoided.
Neurocognitive impairment is frequently observed in pediatric patients with meningoencephalitis (ME) and sepsis-associated encephalopathy (SAE) which represent two relevant central nervous system (CNS) diseases in pediatric patients. It is uncertain, if the the origin of the disease, located primarily in the CNS of patients with ME or secondarily in patients with SAE in the course of sepsis, is of importance for the severity of injury to the brain. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed in a comparative study. Biomarkers of neuroaxonal injury are therefore not only of great interest to detect and monitor neurocognitive impairment but also to quantify the severity of brain injury in patients with ME and SAE.
