Clinical studies at the Bonn site

7T-TGA (high-resolution MRI imaging in TGA patients: a retrospective and prospective study)

High-resolution MRI imaging as evidence of a structural cause in transient global amnesia (TGA), in which there is disruption of anterograde and also retrograde memory such that newly learned or experienced material is not retained.

ABCD

The aim of this study is to investigate the influence of rituximab (Rixathon®) on the progression of disease in patients with amyotrophic lateral sclerosis (ALS) compared to a placebo. The study is funded by the German Federal Ministry of Education and Research (BMBF).

ApoE Navi (Influences of the APOE-ε4 genotype and other Alzheimer´s disease (AD) related genes on spatial navigation ability and its neural basis)

The relationship between spatial orientation ability and the context dependence of spatial representations in entorhinal cortex and hippocampus in APOE-ε4 allele carriers is investigated.

ARCA (Autosomal-Recessive Cerebellar Ataxias)

In this DZNE network research project (Autosomal Recessive Cerebellar Ataxia Registry, ARCA registry), modern methods are being used to search for new ataxia genes and biomarkers in autosomal recessive ataxias and early onset ataxias with onset before the age of 40.

COG-HF (Mechanisms of cognitive impairment in chronic heart insufficiency)

Chronic heart failure (chronically reduced pumping capacity) can lead to impairments in memory or other mental functions. The causes of this are still mainly unclear and will be investigated in this study.

DANCER (Establishment of a Recruitment Pool of Potential Study Participants, of Realtives and a Control Group for DZNE Studies)

One focus of these studies is the identification of early, specific changes, for example in the blood, so that the diagnosis of a neurodegenerative disease such as dementia or Parkinson's can be made at a very early stage. This enables a better understanding of the diseases and supports the development of new forms of therapy.

DANCER-FTD (Recruitment of Realtives and a Control Group for the DESCRIBE-FTD Study)

In order for us to assess study outcomes of patients with neurological frontotemporal dementia (FTD), comparative studies with relatives of patients with FTD as well as interested individuals without a diagnosis of neurodegenerative disease are needed.

DANCER-PSP (Recruitment of Realtives and a Control Group for the DESCRIBE-PSP Study)

Comparative studies with relatives of patients with PSP and interested individuals without a diagnosis of neurodegenerative disease are needed to assess study outcomes of patients with progressive supranuclear palsy (PSP).

DESCRIBE (DZNE - Clinical Register Study of neurodegenerative Disorders)

The aim of the DESCRIBE study is to use the examination results obtained in the course of normal patient care together with findings from diagnostics on biomaterials, including genetic analysis, for scientific purposes.

DESCRIBE-FTD (DZNE - Clinical Registry Study on Frontotemporal Dementia (FTD))

DESCRIBE-PSP (DZNE - Clinical Registry Study on Progressive Supranuclear Paresis (PSP))

ENABLE (Patient- and care-related benefits of amyloid PET imaging)

The aim of the ENABLE trial is to test whether amyloid PET screening has the potential to improve the care of dementia patients in the German health care system and thus contribute to the preservation or slowed loss of everyday functions.

ESMI (European Spinocerebellar Ataxia Type 3/Machado-Joseph Disease Initiative)

The aim of this study is to assemble a trial-ready cohort of sufficient size consisting of patients with spinocerebellar ataxia type 3 (SCA 3) and first-degree relatives, so-called at-risk individuals, for future drug trials.

Eye and neurodegeneration

Eye and neurodegeneration: Changes in nerve fibers and vessels in the eye in neurodegenerative diseases.

HSP-Net (Networking Project on Hereditary Spastic Paraplegia)

Spastic spinal paralysis (HSP) is a rare, often hereditary, slowly progressive disease characterized by a spastic gait disorder. The HSP project involves the establishment and conduct of a multicenter study of the natural longitudinal course of hereditary spastic spinal paralysis.

NIO752 (Safety, Tolerability and Pharmacokinetics of Multiple Ascending Doses of NIO752 in Progressive Supranuclear Palsy)

Adult patients suffering from progressive supranuclear gaze palsy (PSP) are eligible for enrollment in this study. Gaze palsy is a form of atypical Parkinson's syndrome.

PROFA (Patient-reported, health economic and psychosocial outcomes in Friedreich Ataxia)

Investigation of the impact of Friedreich's ataxia on patient-related, health economic, and psychosocial outcomes using self-reported data collection via a patient-centered e-health app.

Prospect-AD (Population-based screening over speech for clinical trials in Alzheimer’s Disease)

Subjective memory impairment (SCD) or mild cognitive impairment (MCI) may be associated with an increased risk of dementia later in life. Early preventive measures can potentially reduce the risk of dementia. This requires early detection of early signs of cognitive impairment.

SCA Registry (Registry for Spinocerebellar Ataxies (SCA))

The goals of the SCA Registry are to characterize the natural history of the disease, identify prognostic factors, and develop novel imaging and biochemical biomarkers. By including at-risk individuals, we place a special focus on studying the preclinical disease phase.

SPORTAX-NHS (Observational Study on Adult Onset Sporadic Ataxias)

The SPORTAX study aims to precisely characterize the two forms of the disease and to compare the courses of the disease. In addition, factors are to be identified that allow a more precise assignment of the disease at an early stage and that can influence the development of the disease.

TAK-341-2001 (A Study of TAK-341 in Treatment of Multiple System Atrophy)

This study helps answer important medical questions about an investigational drug called TAK-341, such as: How effective is it in treating people who have MSA? What side effects may occur?

Vorinostat_AD (A dose-finding study to address safety (and efficacy) of Vorinostat in Alzheimer‘s Disease)

The objective of this clinical trial is to determine a tolerable and tolerable dose of the drug vorinostat in elderly patients with mild Alzheimer's disease.
