Trial overview
These records describe interventional clinical trials, which means researchers gave a treatment or procedure and then measured the results.[1][2] The trials investigate XYLOMETAZOLINE HYDROCHLORIDE in two different clinical settings: COPD and nasotracheal intubation.[1][2] Both studies are in Phase 3, which is a later stage of testing in people.[1][2]
COPD study and physical capacity
One trial, NCT 2024-520177-12-00, is an authorised Phase 3 study in people with Chronic Obstructive Pulmonary Disease (COPD).[1] Its goal is to assess the effect of one dose on the physical capacity of patients with COPD.[1] The main result being measured is walking distance, which helps show how far a person can walk as a sign of physical ability.[1]
Intranasal analgesia study during nasotracheal intubation
The second trial, NCT 2023-506644-17-01, is a completed Phase 3 blinded triple crossover study in patients undergoing nasotracheal intubation.[2] A blinded triple crossover study means the treatment order is compared across several approaches, and the people involved do not know which treatment is being given at a given time.[2] This study compares cocaine, lidocaine/xylometazoline, and saline for intranasal analgesia, which means pain relief given through the nose.[2]
Study design and participants
The COPD study includes patients with a long-term lung disease that can make breathing difficult.[1] The intubation study includes patients who need a breathing tube placed through the nose.[2] Together, these trials show that XYLOMETAZOLINE HYDROCHLORIDE is being studied in very different groups of patients rather than in one single disease area.[1][2]
Endpoints and outcome measures
A primary outcome is the main result a study is designed to measure.[1][2] In the COPD study, the primary outcome is walking distance.[1] In the intubation study, the primary outcome is self-reported pain during the procedure, measured with a visual analogue scale from 0 to 100.[2] This scale is a simple way for patients to rate pain, with higher numbers showing more pain.[2]
Trial status and enrollment
The COPD study is listed as Authorised and plans to include 64 participants.[1] The intranasal analgesia study is listed as Completed and included 12 participants.[2] Enrollment means the number of people planned or included in a study.[1][2]
