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.
NOTCH signaling in the skin exerts a pivotal role in the regulation of normal keratinocytes turnover by mediating the balance between proliferation, differentiation, apoptosis and autophagic flux progression. Two skin diseases are characterized by the presence of gene variants that cause an impairment in NOTCH signaling: hidradenitis suppurativa(HS) and Dowling-Degos disease(DDD). To date, both HS and DDD are orphan diseases still lacking of specific treatments. This project aims at improving the current knowledge on the pathogenesis of HS and DDD, by deepening the understandings on the role played by keratinocytes in these pathologies and also by determining why mutations found in the same pathway cause different diseases. This study aimed to obtain in vitro models, derived directly from patients (from hair follicles) and from keratinocytes (HaCaT) cell cultures, for the study of these skin pathologies and also for the testing of novel innovative therapies such as photobiomodulation therapy.
The aim of the study is to apply a novel clinical investigation protocol in patients with Phosphodiesterase 6A (PDE6A), PDE6B and Rhodopsin (RHO)-based retinitis pigmentosa. This novel, multimodal clinical examination protocol describes and correlates structural, functional and metabolic aspects during natural disease development. Test-retest variability of new measurements as well as correlations of the structural, functional, and metabolic changes will be defined to be able to define well-suited readouts for safety and efficacy of future treatment developments before they reach the clinical phase.
The purpose of this study is to test a new method to deliver an approved medicine called Timolol in the eye of participants with glaucoma and pseudophakia. The main questions it aims to answer are how safe the investigational drug is and how the body tolerates it. The study will also check: - how safely the implant is placed in and removed from the eye and how the body responds to the procedure, - how safe different doses of timolol are and how the body handles taking it, - the amount of Timolol released in the bloodstream, - if there is any positive effect on the pressure inside the eye.
Background: PROMISE criteria have been defined for standardized reporting of Prostate-Specific Membrane Antigen (PSMA) PET whole-body stage of prostate cancer. PSMA PET disease extent by PROMISE has been associated with oncologic outcome. Need: Improved prognostication across various stages of prostate cancer is needed for management guidance and study design. Aim: 1. To assess the prognostic value of PSMA PET 2. To compare the prognostic value of PSMA PET with clinical prognostic scores in patients with prostate cancer at various disease stages Inclusion: - Adult patients with - biopsy/histo proven prostate cancer who - underwent PSMA PET (any type) - for staging or re-staging at any stage and who - have at least 3-year overall survival follow-up data available will be included consecutively. Exclusion: - Patients with neuroendocrine prostate cancer - Patients with metastasized or disseminated malignancy other than prostate cancer
Improvement in cancer therapies has led to an increase in the number of women surviving chemotherapy (and other treatments) and overcoming cancer. This patient population presents specific clinical needs as chemotherapy (and other cancer treatments) treatment side effects can lead to early appearance of menopause symptoms and conventional hormonal treatments are contraindicated for these patients. The use of CO2 laser treatment has been shown to provide relief of Genitourinary Syndrome Of Menopause (GSM) symptoms in women and might provide a significant improvement in the quality of life for cancer survivors. The current study is designed to demonstrate the safety and efficacy of CO2 laser for treatment of GSM symptoms in cancer survivors suffering from GSM symptoms, with limited access to hormonal treatment.
The goal of this exploratory method-development study is to to establish and evaluate novel non-invasive methods to monitor airway inflammation induced by allergen challenge (both by instillation during bronchoscopy and by inhalation) in patients with mild allergic asthma. The investigator wants to further profile and develop the allergen challenge model by investigating the utility of various non-invasive monitoring methods. The hypothesis of the project is that local inflammatory changes in the lung induced by allergen can be captured by gas-enhanced magnetic resonance imaging (MRI) and analysis of exhaled breath. The validation of cellular outcome measures and non-invasive inflammometry can be used in future clinical trials for proof of concept of novel anti-inflammatory medications. Participants will undergo - methacholine challenge - 2 inhaled allergen challenges - 2 MRI with hyperpolarized xenon and gadolinium based contrast agent - 2 bronchoscopies with bronchoalveolar lavage (BAL) - segmental allergen challenge during the first bronchoscopy - spirometry - skin prick test and skin prick dilution tests - measurement of particles in exhaled air - nasal filter - nasal lavage - sputum induction - peak flow meter tests - exhaled NO (nictric oxide) - blood sampling (in total approx. 190 ml)
TripleTRE investigates the effect of initial triple combination therapy (oral endothelin receptor antagonist (ERA) + oral phosphodiesterase tyüe-5 inhibitor (PDE-5i) + parenteral treprostinil) compared to double oral therapy (oral ERA + oral PDE-5i) in pulmonary arterial hypertension (PAH) patients (group I) with intermediate-high risk or patients with intermediate-low risk with severe hemodynamic impairment at baseline in a prospective, randomized, unblinded setting with scope of increasing evidence for optimization of therapy concepts in PAH. The effect of initial triple combination therapy vs initial double oral therapy (standard of care (SoC)) will be measured by primary endpoint: (non)response to the assigned treatment.
This is a randomized trial investigating the effect of oscillometric blood pressure monitoring at 2.5-minute intervals - compared to 5-minute intervals - on intraoperative hypotension. Specifically, the investigators will test the primary hypothesis that oscillometric blood pressure monitoring at 2.5-minute intervals - compared to 5-minute intervals - reduces the time-weighted average mean arterial pressure below 65 mmHg in patients having non-cardiac surgery.
The present study seeks to examine the feasibility, acceptance and efficacy of Metacognitive Training-Silver (MCT-Silver) BeWell among older adults (ages 60 years and older) delivered in a community setting (e.g., social-psychiatric community center, nursing homes, etc.).
This is a multicenter, non-interventional study to observe the natural progression of the disease and to study the prevalence of pre-existing antibodies to AAV9 used for gene therapy in a population of patients with PKP2 gene-associated ARVC. Participation from all patients is encouraged regardless of interest in or eligibility for gene therapy.
