Influence of an Inspiratory Muscle Fatigue Protocol on Healthy Youngs on Respiratory Muscle Strength and Heart Rate Variability

Start date: March 4, 2024
Phase: N/A
Study type: Interventional

Respiratory muscle training represents an effective method increasingly utilized in both sports and healthcare domains, employing various devices, among which threshold devices are prominent. The aim of this study is to determine the relationship between inspiratory muscle fatigue and maximal inspiratory pressure, diaphragmatic strength (guided by ultrasound image) and heart rate variability. According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue in healthy youngs could influence cardiorespiratory function. In this study, subjects will be divided into three groups: the experimental group , the activation group and the control group. Measurements of variables, such as maximal inspiratory pressure, heart rate variability and diaphragmatic strength (ultrasound image), will be conducted.

LPFC Organization in Emotion-Duration Difference Estimation

Start date: January 29, 2024
Phase: N/A
Study type: Interventional

To support optimal behavior in daily life, goals and responses following emotional events should ideally incorporate not only the valence and intensity of prior emotional episodes but also their temporal features, such as the relative duration of positive vs. negative attributes. However, how specific brain regions contribute to the integration of temporal and emotional information and promote goal-directed response remains unknown. The goal of this study is to examine how specific brain regions track both emotional and temporal information of dynamic emotional events to inform other related brain regions to guide goal-oriented and context-appropriate actions. The investigators will scan healthy human participants using functional MRI (fMRI) while they view emotional image sequences and track the associated emotional and temporal (duration) information, and act accordingly. The investigators will employ multivariate patterns analysis and pattern similarity analysis to identify brain regions that represent (can decode) emotion, time, and their combined signals, as well as brain regions that represent the associated action goal. In addition, to infer the causal contributions of these brain regions in forming task-relevant representations (emotion, time, and action goal), the same participants will be recruited to receive transcranial magnetic stimulation (TMS) in these regions.

A Study to Learn If the Study Medicine Esomeprazole Changes How the Body Processes the Other Study Medicine Vepdegestrant

Start date: February 23, 2024
Phase: Phase 1
Study type: Interventional

The purpose of the study is to investigate the effect of multiple doses of a proton-pump inhibitor (PPI) esomeprazole on the PK of vepdegestrant under fed conditions in healthy adult participants. All participants in this study will receive one dose of vepdegestrant alone by mouth in Period 1. In Period 2, everyone will receive esomeprazole by mouth once a day for multiple days. Participants will also receive one dose of vepdegestrant by mouth. The levels of vepdegestrant in Period 1 will be compared to the levels of vepdegestrant in Period 2 to determine if the PPI affects how vepdegestrant is processed differently in healthy adults.

BT-600 Single and Multiple Ascending Oral Doses in Healthy Adult Subjects

Start date: January 11, 2024
Phase: Phase 1
Study type: Interventional

This is a randomized, double-blind, placebo-controlled Phase 1 study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of BT-600 when administered in single and multiple ascending doses to healthy participants. The study will enroll up to 48 participants, with participation lasting 2-3 weeks in addition to up to 28 days (about 4 weeks) for screening. The purposes of this study are to learn about the safety and tolerability of single and multiple rising oral doses of BT-600, assess the blood and tissue levels of tofacitinib released from BT-600, and assess the body's effects to the study drug following oral doses of BT-600 in blood and tissue in healthy adult participants. BT-600 is a swallowable drug/device combination product designed to deliver a liquid formulation of tofacitinib to the colon and dispense the study drug throughout the colon. BT-600 consists of two components, the drug part containing a reservoir, which will be filled with liquid tofacitinib, and the drive part. The drive part contains the hardware and software that identifies the colon region and then dispenses the drug to the specific region. The device which contains the drug is referred to as the NaviCap™ device. The NaviCap device is approximately the size of a fish oil pill, is made of plastic material known to be safe for ingestion and has rounded ends for ease of swallowing. Liquid tofacitinib in the reservoir is automatically released when the BT-600 localization technology determines that it has reached the colon. BT-600 passes through the colon and the NaviCap device is excreted via a bowel movement.

A Study to Test How Avenciguat (BI 685509) is Taken up in the Body of People With and Without Liver Problems

Start date: February 29, 2024
Phase: Phase 1
Study type: Interventional

This study is open to people with and without severe liver problems. People can join the study if they are 18 to 80 years of age and have a body mass index (BMI) between 18.5 and 42 kg/m2. Avenciguat (BI 685509) is a medicine that is being developed to treat high blood pressure in the portal vein (main vessel going to the liver). The purpose of this study is to find out whether having liver problems influences how Avenciguat (BI 685509) is taken up in the body. All participants take Avenciguat (BI 685509) once as a tablet. Participants are in the study for slightly longer than 1 month. Following the screening period of about 4 weeks, they stay at the study site for 4 nights. Afterwards, there are 2 visits to the study site. The site staff measures the amount of Avenciguat (BI 685509) in the blood. The doctors also regularly check participants' health and take note of any unwanted effects.

Influence of an Inspiratory Muscle Fatigue Protocol on Healthy Youngs on Respiratory Muscle Strength, Vertical Jump Performance and Muscle Oxygen Saturation

Start date: March 3, 2024
Phase: N/A
Study type: Interventional

Respiratory muscle training represents an effective method increasingly utilized in both sports and healthcare domains, employing various devices, among which threshold devices are prominent. The aim of this study is to determine the relationship between inspiratory muscle fatigue and muscular strength in lower limbs, in both healthy and pathological subjects, as well as the association between such fatigue and other variables, including maximal inspiratory pressure and muscle tissue oxygen levels. According to our hypothesis, the execution of a protocol inducing inspiratory muscle fatigue in healthy youngs could influence muscular strength, exercise capacity and muscle tissue oxygenation. In this study, subjects will be divided into three groups: experimental group , activation group and control group. Measurements of variables, such as maximal inspiratory pressure, peripheral muscle tissue oxygen levels, diaphragmatic strength (ultrasound image) and vertical jump performance, will be conducted.

The Gut-Lung Axis and Respiratory Illness in Children

Start date: February 4, 2024
Phase:
Study type: Observational

The goal of this single-centre observational study conducted at the Royal Hospital for Children in Glasgow, Scotland, is to employ a multi-omics approach to investigate the "gut-lung axis" in health and disease. Part A is a cross-sectional study design investigating the postulated bidirectional link between the gut and lung microbiomes in children suffering from respiratory or gastrointestinal conditions. Children with no GI or respiratory issues attending for orthopaedic care will be used as a benchmark for a healthy gut-lung axis. The main questions we aim to answer are: - What does a healthy gut-lung axis look like? - Do children with respiratory issues show an altered gut microbiome? - Do children with GI issues show an altered lung microbiome? Part B is a longitudinal study design, that aims to assess the effects of biologics on the gut-lung axis by comparing the gut and lung microbiomes in children with asthma at two time-points who are indicated to start biologics therapy (Asthma treatment) or will not receive biologics therapy (asthma control). Participants will provide: - airway samples (to investigate the lung microbiome) - blood samples (to assess inflammatory and metabolic factors which may mediate communication between the two sites) whilst under general anaesthetic for a treatment related to their standard of care - stool samples (to assess gut microbiome) - dietary information (food diary and/or food frequency questionnaire) to assess relationships between diet and the gut-lung axis.
