Study summary

The main objective is to evaluate the efficacy of Azéol Spray Nasal, taken two times a day, versus placebo on nasal congestion in subject with common cold.

Read the detailed description

This study is designed as a multicentric, randomized, double-blind, placebo-controlled with two-arm parallel groups clinical trial. 144 subjects presenting with early symptoms of common cold will be recruited for this study, according to the defined inclusion and exclusion criteria. The main objective is to evaluate the efficacy of Azéol Spray Nasal (Bifidobacterium breve LA 708, extract of cypres Cupressus sempervirens L., extract of Leguminosae Glycyrrhiza glabra L., glycerin and mannitol), taken two times a day, versus placebo on nasal congestion in subject with common cold.

    Time frame: 7 days

  7. Time to onset of subjective relief symptoms from day 1

    relief of symptoms defined when symptom absent is declared for all symptoms with a patient questionnaire

    Time frame: 7 days

  8. Subject's assessment of common cold feeling compared to the day before

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2021 to primary completion in Mar 2023, 16 months.

Of 46 interventional studies with no phase under Nasal Obstruction, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 43. This study's 16 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 14, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
