Brief Summary

This study looked at whether frontline healthcare workers could use a drug-free nasal spray twice a day for 8 weeks, whether it was safe, and whether they found it acceptable. The spray used in the study (Profi Nasal Spray, Akita Biosciences) was a cosmetic nasal hygiene product made from ingredients already used in nasal and topical products. Healthcare workers at a public hospital in New York City were randomly assigned to use the spray twice a day for 8 weeks or to receive no spray. The study asked:

  • Feasibility: Could busy healthcare workers use the spray as directed over 8 weeks?
  • Safety: Were side effects more common in people who used the spray than in people who did not?
  • Acceptability: How did users feel about the spray, and did they stay in the study? Every 3 days, participants answered a short online questionnaire about spray use, side effects, respiratory symptoms, and contact with patients who had COVID-19, influenza, or RSV. Spray use was checked by weighing the bottles at weeks 4 and 8. To better understand acceptability, about 20 spray users also took part in one-on-one interviews about what it was like to use the spray, including ease of use, fitting it into a daily routine, and anything that made it harder to use.

Outcome Measures

Primary Outcomes (3)

  • Feasibility of using the nasal spray

    Number of eligible healthcare workers who consented and enrolled in the study and continued to use the nasal spray.

    8 weeks

  • Safety: Number of Participants With Adverse Events

    Adverse events in the intervention and control groups, including new nasal discomfort or irritation, stinging or burning, changes in smell or taste, nosebleeds, and respiratory events, with duration and severity.

    12 weeks

  • Acceptability: Adherence to Daily Use and Study Dropout

    Adherence: proportion of intervention participants with less than 20% of the expected amount of spray remaining in the bottle (by weight), indicating use of more than 80% of expected doses. Dropout: proportion of participants in each group who withdrew or were lost to follow-up.

    Week 4 and Week 8

Study Arms (2)

Nasal Spray Arm

EXPERIMENTAL

Participants used the nasal spray, one spray in each nostril twice daily, for 8 weeks. Participants received one bottle (about 4 weeks of supply) at enrollment and a second bottle at week 4. Remaining spray was weighed at weeks 4 and 8 to measure adherence.

Other: Nasal Spray

No Spray (Control)

NO INTERVENTION

Participants did not receive a nasal spray. They completed the same questionnaires and study visits as the spray group.

Interventions

Profi Nasal Spray (Akita Biosciences) is a drug-free nasal spray that forms a thin coating in the nose to help trap and clear airborne particles. It is made from ingredients already used in commercially available nasal and topical products.
