Thermosensitive Gel Nasal Spray With Exosomes, Azelastine, and Interferon for Acute Phase of Chronic Sinusitis (CRS)
7 juni 2026 uppdaterad av: The First Affiliated Hospital of Xinxiang Medical College
A Single-Centre, Randomised, Double-Blind, Placebo-Controlled Exploratory Clinical Study of a Thermosensitive Gel Nasal Spray Containing Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes, Azelastine and Recombinant Human Interferon α-2b for the Treatment of Chronic Rhinosinusitis (Acute Phase)
This study tests a new nasal spray for adults (18-65 years) with chronic sinusitis experiencing an acute phase.
The spray contains a temperature-sensitive gel that turns into a soft gel inside the nose to slowly release three active ingredients: stem cell exosomes (to repair nasal lining), azelastine (an antihistamine and anti-inflammatory drug), and interferon alpha-2b (an antiviral agent).
The study aims to evaluate safety and see if the spray can reduce symptoms, fight viruses, and improve quality of life.
Participants will be randomly assigned to one of three groups: triple spray, dual spray (without exosomes), or placebo (gel only).
Treatment is twice daily for 4 weeks, with follow-up visits up to day 90.

Betingelser
Detaljerad beskrivning
This exploratory, single-centre, randomised, double-blind, placebo-controlled study enrolls 108 participants (allowing 20% dropout) in a 1:1:1 ratio.
Group A receives thermosensitive gel + exosomes (1×10^10 particles/mL) + azelastine (0.1%) + interferon α-2b (1×10^5 IU/mL).
Group B receives gel + azelastine + interferon (without exosomes).
Group C receives blank gel.
The gel matrix (Poloxamer 407 18% + chitosan hydrochloride 0.5%) is liquid at room temperature and gels at nasal temperature (33-35°C).
Treatment duration is 28 days (twice daily, 2 sprays per nostril).
Single-spray doses: exosomes 2×10^9 particles, azelastine 0.2 mg, interferon 2000 IU.
Follow-up at day 42 and day 90.
Primary outcome: safety (adverse events, CTCAE v5.0).
Secondary outcomes: Lund-Kennedy score, SNOT-22, VAS, response rate, SF-36.
Exploratory: viral clearance, inflammatory cytokines, bacterial load, mucosal barrier markers.
The study is conducted at The First Affiliated Hospital of Xinxiang Medical College.
Ethics approval obtained.
Results will be published.
