NCT ID: NCT06407102 Not yet recruiting - Nasal Disease Clinical Trials

Collection of Primary Human

BIONOSE
Start date: June 30, 2024
Phase: N/A
Study type: Interventional

Treatment and prevention of respiratory infections are of great interest in many medical areas. Create a physical device covered by primary human nasal cells could be very usefull in order to analyse delivery and efficiency of drugs. In this context the aim of this project is to create a collection of primary cells from the human nasal epithelium. This collection will be realised during programmed surgery, thanks to a specific device dedicated to collect nasal cells. Then the cells will be sent to the lab in order to grow at the air-liquid interface, which is an excellent 'ex vivo' model for their study.

NCT ID: NCT06305520 Enrolling by invitation - Nasal Surgery Clinical Trials

Medical Device Pivotal Study to Injection With SkinPlus-HYAL Implant Lidocaine vs RESTYLANE Lidocaine in of Nasolabial Folds

BPLUS-02
Start date: March 10, 2023
Phase: N/A
Study type: Interventional

Purpose : This investigation intends to demonstrate that the investigational device, SkinPlus-HYAL Implant Lidocaine, is non-inferior to the comparator device, RESTYLANE Lidocaine, in terms of temporary wrinkle reduction effect, safety, and injection site pain when applied on nasolabial folds in adults. Design : 24-week efficacy and safety evaluation and additional 48-week long-term safety and efficacy evaluation with a multi-center, randomized, subject- & evaluator-blind, matched pairs, active controlled, none-inferiority, confirmatory design Treatment Group: Application of the investigational medical device (SkinPlus-HYAL Implant Lidocaine) Control Group: Application of the comparator device (RESTYLANE Lidocaine) Population: Number of subject 100 * In this investigation, the same subject receives both test and control treatments, one on each side of the nasolabial folds (matched pairs design).

NCT ID: NCT05948800 Recruiting - Nasal Obstruction Clinical Trials

Impact of Nasal Isotonic Solution Irigation on Healthy Athletes' Nasal Flow and Nasal Obstruction Exercise Outcomes

ISOtastic!
Start date: April 16, 2023
Phase: N/A
Study type: Interventional

Nasal patency is an important component of performing exercises because it helps in humidifying, heating and filtering the inhaled air. However, many athletes and exercisers experience difficulty breathing through their nose, which can affect their breathing and performance. Namely, during sports activities and greater physical effort, there is increased air flow, which causes significant dehydration and cooling of the mucous membrane of the upper respiratory system. This dehydration is associated with the release of inflammatory mediators, which can ultimately lead to narrowing of the airways (eg in athletes with asthma). However, in all athletes, regardless of whether they have asthma or not, damage to the airways can occur because during exercise, hyperpnea exposes the respiratory epithelium to increased physical forces and pressure, which leads to the risk of exfoliation of the previously dehydrated epithelial cells of the nose and even their complete separation. Repeated stretching and compression can negatively affect the functionality of the epithelium and, with repeated exposure and damage, lead to structural and functional changes. Rinsing the nose with a hypertonic or isotonic solution of seawater is a potential solution for nasal obstruction because after rinsing, the airflow through the nose improves and symptoms of obstruction are reduced. However, the effects of using nasal lavage solutions along with exercise in elite athletes are not yet known. The potential synergy of exercise and isotonic seawater solution as a nasal spray on airflow and the subjective impression of nasal patency in healthy individuals has not been sufficiently investigated5. Research question What is the effect of an isotonic seawater solution applied as a nasal spray on nasal airflow and the subjective impression of nasal obstruction in healthy athletes? Hypothesis An isotonic seawater solution applied as a nasal spray will improve nasal airflow and the subjective impression of nasal obstruction in healthy athletes.

NCT ID: NCT04046393 Recruiting - Nasal Disease Clinical Trials

Investigating the Effect of Herbal Medicine Nasal Irrigation on Treatment of Chronic Rhinitis and Sinusitis

Start date: December 31, 2019
Phase: Phase 2/Phase 3
Study type: Interventional

This study investigate the nasal irrigation with Traditional herbal medicine extract-saline isotonic solution in the treatment of chronic rhinitis and sinusitis. Half of participants will receive Traditional herbal medicine extract-saline isotonic solution nasal irrigation, while the other half will receive saline alone nasal irrigation.

NCT ID: NCT03587545 Active, not recruiting - Healthy Volunteers Clinical Trials

Study of Probiotic Potential of Lactobacillus Strains in the Upper Respiratory Tract After Nasal Spray Application

Start date: June 1, 2018
Phase: N/A
Study type: Interventional

Probiotics are defined as "live micro-organisms that, when administered in adequate amounts, confer a health benefit to the host" (Hill et al, 2014). These microbes are generally applied in the gastrointestinal tract via fermented food products or capsules. In previous research, the investigators isolated bacterial strains with potential probiotic properties for the upper respiratory tract based on in vitro laboratory tests, in vivo mice experiments and genome sequencing. In this study, the investigators want to deliver the Proof-of-Concept that the most promising isolated strain, Lactobacillus casei AMBR2 (LAMBR2) and the well-documented probiotic strain Lactobacillus rhamnosus GG (LGG) also have interesting properties in humans, i.e. that these strains are able to -temporarily- persist in the upper respiratory tract of healthy volunteers and CRS patients after daily nasal application via a nasal spray for 2 weeks. In addition, the investigators aim to explore whether the application of these strains has an impact on the nasopharyngeal microbiome via 16S rRNA amplicon sequencing and dedicated qPCR analysis. Therefore, bacterial DNA from nasal swabs will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the bacterial species present in these samples. Furthermore, the concentration of the Lactobacillus and specific pathogens will be monitored via qPCR.
