Nasal congestion, Nasal Obstruction

A Study to Learn More About How Well Oxymetazoline HCl 0.05% Nasal Gel Works and How Safe It Is in Healthy Adults

Trial purpose

Nasal congestion (a “stuffy nose”) is a common symptom of colds and seasonal or year-round allergies. It happens when the tiny blood vessels and tissues inside the nose swell and leak fluid, producing more mucus. That swelling and extra fluid make the nasal passages narrower, which can make it hard to breathe through the nose, sleep, or do daily activities.

Oxymetazoline works on alpha-adrenergic receptors in the tiny blood vessels inside the nose. When these receptors are activated, the blood vessels tighten (constrict), which helps reduce swelling and open the nasal passages.

The study drug, oxymetazoline hydrochloride (HCl) 0.05% nasal gel, is a gel form of a well-known decongestant that is typically available as a nasal spray. The gel may remain in contact with the nose longer than a spray and could feel different to use.

The main purpose of this study is to learn how well a single dose of oxymetazoline HCl 0.05% nasal gel relieves nasal congestion within the first 2 hours after dosing using two different measures. The study will also look at safety and how well people tolerate the gel.

Primary Outcome

  • The change from baseline (CFB) in nasal congestion considered by timepoint and difference over 2 hours post-treatment
    Subjective feeling of nasal congestion will be evaluated by the 100 mm Visual Analog Score (VAS) (0-100 mm): 0 being completely clear and 100 being completely obstructed.
    date_rangeTime Frame:
    From baseline to 2 hours post-administration

Secondary Outcome

  • Onset of action: Timed frequency using VAS
    VAS (0-100 mm): 0 being completely clear and 100 being completely obstructed. VAS scoring will be assessed at baseline and from 10 seconds post-study intervention administration to establish the earliest onset of action.
    date_rangeTime Frame:
    From baseline to 2 hours post-administration
  • The change from baseline in Peak Nasal Inspiratory Flow (PNIF) measurement via nasal peak flow by timepoint and averaged over 2 hours post-treatment
    The participant’s PNIF will be measured with a device coupled to the anterior region of the nose through a mask connected to a plastic cylinder through which the forced inspired air passes. Participants will be trained on the performance of PNIF prior to dosing. Each participant will undergo 3 maneuvers at each specified timepoint, and all 3 attempts will be documented. Only the highest value of the 3 maneuvers will be used for assessment of endpoint analysis.
    date_rangeTime Frame:
    From baseline to 2 hours post-administration
  • Number of participants with adverse events (AEs), serious adverse events (SAEs), and Treatment Emergent AEs (TEAEs)
    date_rangeTime Frame:
    From baseline to 2 hours post-administration
  • Participant satisfaction/tolerability of study interventions
    Participant satisfaction/tolerability will be evaluated by means of a five-point verbal rating scale to responses to a questionnaire (0 = very good, 1 = good, 2 = satisfactory, 3 = minimal, 4 = none).
    date_rangeTime Frame:
    At 2 hours post-administration
