Observational Study of RHINOSEDAL in Acute Nasal Obstruction (RHINOSEDAL)

27. mai 2026 oppdatert av: Laboratoires Elerte

Prospective Multicenter Before-After Study in Children and Adults Treated for Acute Nasal Obstruction With RHINOSEDAL

This prospective, multicenter, national, observational, non-interventional post-market clinical follow-up study evaluates the performance and safety of RHINOSEDAL in children and adults presenting with acute nasal obstruction associated with common cold, allergic or non-allergic rhinitis, or rhinosinusitis. Patients prescribed RHINOSEDAL in routine care will be followed for 6 ±1 days using patient-reported outcome measures including the NOSE score.

Detaljert beskrivelse

RHINOSEDAL is a CE-marked class IIa medical device indicated in adults and children older than 2 years to relieve nasal congestion through an osmotic mechanism in cases of common cold, allergic or non-allergic rhinitis, and sinusitis. This prospective observational study is conducted in real-life conditions of use in French general practice. The decision to prescribe RHINOSEDAL is made before and independently from study participation. Patients aged 8 years and older with acute nasal obstruction evolving for less than 48 hours and baseline NOSE score >40/100 will be included. Patients will complete a self-assessment diary from Day 1 to Day 6 ±1. The primary endpoint is the proportion of patients achieving a decrease greater than 24 mm in the NOSE score between baseline Day 0 and the Day 3 evening assessment. Secondary endpoints include additional NOSE responder analyses, daily NOSE evolution, individual NOSE item evolution, social activity impairment, patient global assessment of effectiveness, associated signs, safety, device deficiencies, and compliance.

Patients treated with RHINOSEDAL
Children and adults aged 8 years or older consulting a general practitioner for acute nasal obstruction associated with common cold, rhinitis, or rhinosinusitis and prescribed RHINOSEDAL in routine care.
Enhet: RHINOSEDAL
RHINOSEDAL is a ready-to-use hypertonic nasal spray containing natural sea water, tamarind extract and mallow extract. It acts mechanically through osmotic decongestion and cleansing of the upper airways. It is used according to the instructions for use and physician prescription.

Tiltaksbeskrivelse
Tidsramme
NOSE responder rate at Day 3
Tidsramme: Day 3 evening
Percentage of patients with a reduction greater than 24 mm in the NOSE (Nasal Obstruction Symptom Evaluation) score between baseline Day 0 and the Day 3 evening assessment. The NOSE questionnaire includes 5 items rated from 0 to 4 and normalized to a 0-100 score, where higher scores indicate more severe nasal obstruction symptoms. For this study, the recall period was adapted from one month to the previous 24 hours.

Daily evolution of social activity impairment
Tidsramme: Day 0 to Day 6 ±1 day or early termination

Patient global assessment of effectiveness
Tidsramme: End of study visit at Day 6 ±1 day or early termination
Patient-rated overall effectiveness using a 5-point numerical scale: 0 = not effective at all; 1 = very slightly effective; 2 = slightly effective; 3 = fairly effective; 4 = very effective.
