NCT ID: NCT05186987 Completed - Clinical trials for Pulmonary Hypertension

Visa-versa! Breaking Instead of Pushing the Pedals-A

Start date: February 15, 2022
Phase: N/A
Study type: Interventional

Eccentric muscle work is defined as lengthening of a muscle while applying force. It was shown that with eccentric work, muscles are able to perform four times as much power compared to usual concentric work, which results in huge training gain with a highly decreased oxygen demand and thus lower cardiovascular load. Pulmonary hypertension (PH) is a chronic condition associated with significant reduced exercise capacity and increased morbidity and mortality, resulting in reduced quality of life. Physical training has been shown to be beneficial in PH, even in severely limited patients. However, due to cardiopulmonary constraints in PH, training intensities may be very low, so that many patients are physically almost unable to perform exercise on a high enough level to maintain muscle mass. A low body muscle not only feeds the vicious cycle of decreasing exercise capacity, but also has many deleterious metabolic and immunological consequences which further increase disability and decrease quality of life in PH. Thus, eccentric training, which allows to gain muscle mass with a low stress to the cardiopulmonary unit may to be highly beneficial for patients with PH and allied cardiopulmonary disease, such as chronic obstructive pulmonary disease (COPD) and heart failure. Therefore, the objective of the trial is, to compare differences in oxygen uptake (peak VO2 [l/min]) and other physiological measures during similar cardiopulmonary exercise test protocols of eccentric- vs. concentric cycling in PH- patients and comparators with or without other cardiopulmonary diseases.

NCT ID: NCT05184270 Completed - Parkinson Disease Clinical Trials

Integration of Auditory, and Deep Brain Stimulation to Enhance Deep Sleep in Parkinson's Disease

Start date: November 10, 2021
Phase: N/A
Study type: Interventional

The study is an open-label trial to validate the local field potential (LFP) activity in the subthalamic nucleus (STN) for slow-wave detection during acoustic stimulation during nighttime sleep in Parkinson's disease patients that receive deep-brain-stimulation (DBS) therapy with the novel PERCEPTâ„¢ DBS system.

NCT ID: NCT05183191 Completed - Diabetes Clinical Trials

The HEADWIND Study - Part 3

Start date: November 29, 2021
Phase: N/A
Study type: Interventional

To analyse driving behavior of individuals with type 1 diabetes in eu- and mild hypoglycaemia using a validated research driving simulator. Based on the driving variables provided by the simulator the investigators aim at establishing algorithms capable of discriminating eu- and hypoglycemic driving patterns using machine learning classifiers.

NCT ID: NCT05182840 Completed - Clinical trials for Kidney Disease, Chronic

A Study to Test Whether Different Doses of BI 690517 Alone or in Combination With Empagliflozin Improve Kidney Function in People With Chronic Kidney Disease

Start date: January 11, 2022
Phase: Phase 2
Study type: Interventional

This study is open to adults with chronic kidney disease. People with and without type 2 diabetes can take part in this study. The purpose of this study is to find out whether a medicine called BI 690517 improves kidney function in people with chronic kidney disease when taken alone or in combination with a medicine called empagliflozin. In the first part of the study, participants take empagliflozin or placebo as tablets every day for 2 months. Placebo tablets look like empagliflozin tablets but do not contain any medicine. In the second part, participants are divided into several groups. Depending on the group, the participants then additionally take different doses of BI 690517 or placebo as tablets for 3.5 months. In this case, placebo tablets look like BI 690517 tablets but do not contain any medicine. Participants are in the study for about 6 months. During this time, they visit the study site about 12 times. Where possible, about 4 of the 12 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Participants collect urine samples at home. These samples are then analysed to assess kidney function. At the end of the trial the results are compared between the different groups. The doctors also regularly check participants' health and take note of any unwanted effects.

NCT ID: NCT05175430 Completed - Healthy Clinical Trials

Effects of SERT Inhibition on the Subjective Response to LSD in Healthy Subjects

SERT-LSD
Start date: October 24, 2022
Phase: Phase 1
Study type: Interventional

Lysergic acid diethylamide (LSD) is a classic serotonergic psychedelic acting on the serotonin 5-HT2A receptor. LSD is used recreationally and in psychiatric research. First studies suggest efficacy in psychiatric disorders, such as depression and anxiety. SSRIs like paroxetine are first-line treatments for depression and anxiety disorders. Paroxetine acts as a serotonin transporter (SERT) inhibitor. However, the link between this mechanism and its positive effects on mood remains to be established. Several studies suggest a possible downregulation of postsynaptic serotonin (5-HT) receptors such as the 5-HT2A receptor. The aim of the study is to assess whether SERT inhibition reduces expression of the gene coding for the 5-HT2A receptor and the response to LSD.

NCT ID: NCT05171764 Completed - Clinical trials for Cardiovascular Diseases

Dual Energy Cardiac CT Data Collection and Evaluation

Start date: November 14, 2022

This study is intended to collect clinical feasibility data using this prototype research mode for the purposes of understanding potential clinical impact, potential limitations and strengths, and to further develop the technique through development of image reconstruction and processing approaches or identification of other areas of development required.

NCT ID: NCT05167084 Completed - Clinical trials for Glucocorticoid Effect

Acute Consequences Of Food-induced Glucocorticoid Secretion In Healthy Individuals

Gluco-Feed
Start date: February 8, 2022
Phase: Early Phase 1
Study type: Interventional

In a randomized, cross-over study, 20 healthy volunteers will receive a block and replace therapy that mimics physiological GC rhythm (metyrapone plus hydrocortisone) or placebo. Participants will undergo two identical overfeeding periods with each treatment. With the block and replace therapy, food-induced GC peak will be suppressed. Metabolic and autonomic parameters will be compared to reveal, whether GCs mediate the physiological adaptions to excessive food intake. Understanding acute effects of GCs upon food intake is critical, since repetitive disruptions of GC secretion may become harmful in chronic conditions.
