Trial overview
The source data describe one interventional clinical trial investigating Sodium Nitrite in a respiratory setting, although the study title uses the name RESP30X and includes inhaled formulations. The trial was designed to assess safety and tolerability in people with non-cystic fibrosis bronchiectasis and confirmed high-titre respiratory potentially pathogenic micro-organisms.[1]
This study was completed and enrolled 67 participants.[1]
Who was studied
The target population was people with non-cystic fibrosis bronchiectasis, which is a long-term lung condition where the airways are damaged and widened.[1]
The study also required confirmed high-titre respiratory potentially pathogenic micro-organisms (PPMs), including Pseudomonas aeruginosa or other similar germs that may cause disease.[1]
In simple terms, the trial focused on people who had both a chronic lung problem and evidence of harmful bacteria in the airways.[1]
What was tested in the trial
The interventions listed in the source data were RESP302, salbutamol, and RESP303, all given by inhalation use.[1]
The brief summary says the study aimed to assess the safety and tolerability of RESP30X in participants with confirmed high-titre respiratory PPMs.[1]
Safety means looking for unwanted health problems, while tolerability means how well people can receive the treatment without major difficulty.[1]
Outcomes measured
The primary outcomes included the incidence, intensity, causality, and seriousness of treatment-emergent adverse events (TEAEs).[1]
TEAEs are health problems that begin or become worse after treatment starts.[1]
Researchers also measured changes in laboratory values, including haematology and clinical chemistry, at each time point.[1]
They further tracked changes in vital signs such as blood pressure, heart rate, temperature, respiratory rate, and oxygen saturation (SpO2).[1]
Trial phase and status
This was a Phase 1 trial, which is an early stage of clinical research that mainly checks safety and tolerability.[1]
The study status is listed as completed, so the planned testing and data collection were finished.[1]
What the trial means for patients
For patients, this trial shows that Sodium Nitrite was being explored in a small early study for a specific lung condition linked to airway bacteria.[1]
The main question was not whether the treatment cures disease, but whether it can be studied safely in this group and what short-term changes appear in tests and vital signs.[1]
Because the study was completed, its data can help researchers decide whether larger studies should be done later.[1]
