Study summary

Primary Objectives:

  • To demonstrate that the aggravation of seasonal allergic rhinitis symptoms in the presence of pollutants is observed using an Environmental Exposure Unit.
  • To evaluate the efficacy of fexofenadine hydrochloride in subjects suffering from seasonal allergic rhinitis symptoms aggravated in the presence of diesel exhaust particulates.

Secondary Objective:

To evaluate the safety of a single dose of fexofenadine hydrochloride 180 mg.

Inclusion criteria

  • Males or females between the ages of 18 and 65 suffering from seasonal allergic rhinitis provoked by ragweed pollen.
  • Having a 2-year history of seasonal allergic rhinitis with positive skin prick test to ragweed allergen at screening with a wheal diameter at least 3 mm larger than that produced by the negative control.
  • Subjects with antecedents of allergic seasonal allergic rhinitis symptom aggravation when exposed to pollen and air pollutants (i.e., cleaning products, diesel, paints).
  • Subjects having a total nasal symptom score ≥3 in Period 1 (Visit 2).

Exclusion criteria

Exclusion criteria:

  • History of anaphylaxis to ragweed pollen.
  • History of asthma. Mild asthmatics treated only with pro re nata short-acting beta2-agonists, 2 doses or less per week can be enrolled.
  • History of chronic sinusitis.
  • History of systemic disease affecting the immune system.
  • Evidence of any active or suspected bacterial, viral, fungal or parasitic infections within 30 days prior to allergen challenge.
  • Any history of Grade 4 anaphylaxis due to any cause as defined by the Common Terminology Criteria for Adverse Event grading criteria ("Life threatening consequences: urgent intervention indicated").
  • Presence or history of drug hypersensitivity to fexofenadine.
  • Subjects receiving build-up injections of pollen allergen immunotherapy (those on stable maintenance dosing can be included).
  • Subjects taking any forbidden treatments/nutriments.

What researchers measure

Primary outcomes

  1. Total nasal symptom score (TNSS)

    Assessed by measuring change in the area under the curve (AUC) of the TNSS during Period 1 and 2

    Time frame: From hour 0 to hour 12 in Period 1 and Period 2

  2. TNSS

    Assessed by measuring change in the AUC of the TNSS from hour 2 (planned time of investigational medicinal product administration) to hour 12 in Period 3

    Time frame: From hour 2 to hour 12 in Period 3

Secondary outcomes

  1. Total symptom score (TSS)

    Assessed by measuring change in the AUC of TSS from hour 2 (planned time of investigational medicinal product administration) to hour 12

    Time frame: From hour 2 to hour 12 in Period 3

  2. Individual symptom score

    Assessed by measuring the change in AUC of individual symptom score from hour 2 (planned time of investigational medicinal product administration) to hour 12

    Time frame: From hour 2 to hour 12 in Period 3

  3. TNSS

    Assessed by change in TNSS by time point from hour 2 to hour 12

    Time frame: From hour 2 to hour 12 in Period 3

  4. Adverse events

    Incidence of adverse events

    Time frame: Up to 4.5 months
