Consumer Preference Study of Two Formulations of Phenylephrine Hydrochloride (Study CL2008-15)(P07530)(COMPLETED)

Phase 3

Completed

• Conditions: Vasomotor Rhinitis; Seasonal Allergic Rhinitis
• Interventions: Drug: Phenylephrine Hydrochloride (HCl) Immediate Release (IR) tablets, 10 mg; Drug: Phenylephrine Hydrochloride (HCl) Extended Release (ER) Tablets 30 mg

• Registration Number: NCT00976209
• Lead Sponsor: Bayer

Brief Summary

This is a randomized, two-way crossover, multicenter study evaluating the consumer preference of Phenylephrine Extended Release Tablets, 30 mg to be taken as one tablet every 12 hours, or Phenylephrine Immediate Release Tablets, 10 mg to be taken as one tablet every 4 hours in subjects with at least mild allergic rhinitis and nasal congestion. Approximately 250 participants will complete a questionnaire after taking one test product for 3 days followed by a 3 day (± 1 day) washout period; and then taking the alternate test product for 3 days. Analysis of which product the consumer preferred, if any, and which product was more convenient, if any, will be evaluated.

• Participants must be willing to stop use of current decongestant and allergy medications during the study, and at the start of the run-in period (Visit 2).
• Participants must have a documented history of allergic rhinitis caused by ragweed allergen for at least the prior two years.
• Participants must have a documented skin testing (prick with wheal >= 3 mm larger than the diluent or intradermal with wheal >=7 mm larger than the diluent control) or a positive in vitro test for specific IgE to the ragweed allergen within the last four years.
• Participants must have signs by clinical evaluation and symptoms of nasal congestion of at least mild severity (sign/symptom clearly present, but minimal awareness; easily tolerated) at Visit 3 following the run-in period and at visit 5 following the washout period.
• Clinical laboratory tests (complete hematology, blood chemistries, urinalysis) must be within normal limits or clinically acceptable to the Investigator/Sponsor. Sponsor will not grant waivers.
• Participants must have a seated (after 5 minutes of rest) systolic/diastolic blood pressure ≤ 138/88 mmHg.
• Participants must have normal or clinically acceptable physical exam and electrocardiogram (ECG) on 12-lead ECG (recorded at 25 mm/s).
• Participants must be free of any clinically significant disease that requires a physician's care and/or would interfere with study evaluations, procedures or participation.
• Participants must agree not to take monoamine oxidase inhibitor (MAOI) for 14 days before study participation and 14 days after the end of the study.
• Participants must be willing to give written informed consent (prior to any study related procedures being performed) and able to adhere to restrictions and examination schedules.
• Female participants of childbearing potential (a non-menopausal female who has not had a hysterectomy, bilateral oophorectomy, or medically documented ovarian failure, including a young woman who has not yet started menstruating) must be using medically acceptable (documented failure rate of less than 1%) birth control measures.
