Preference for Clarinex Tablets vs. Zyrtec Tablets in Patients With Allergies (P03180)

February 7, 2022 updated by: Organon and Co

Preference Evaluation of Clarinex Tablets vs. Zyrtec Tablets in Subjects With Symptomatic Allergic Rhinitis

This was a crossover study designed to see if patients with allergy symptoms preferred Clarinex® or Zyrtec®. Patients were randomized to take 7 days of Clarinex or Zyrtec treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Zyrtec, the patient prefers more.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • had at least a two-year history of seasonal allergic rhinitis and/or perennial allergic rhinitis;
  • currently experiencing symptoms of AR, including nasal symptoms at Visits 2 and 4, prior to entering each treatment phase;
  • had not taken Zyrtec® or Clarinex® within the previous year;
  • were 18 years of age or older;
  • had negative urine test (hCG) for females of childbearing potential;
  • for women of childbearing potential, agreed to use a medically accepted method of birth control;
  • were free of any clinically significant disease (other than AR) that would interfere with study evaluations.

Exclusion Criteria:

  • were pregnant or nursing;
  • had allergic or idiosyncratic reaction to antihistamines;
  • had current or history of frequent, clinically significant sinusitis or chronic purulent nasal discharge;
  • had rhinitis medicamentosa or nasal structural abnormalities (including large nasal polyps and marked septal deviation) that significantly interfered with nasal airflow;
  • in the opinion of the Investigator, were dependent upon nasal, oral or ocular decongestants, nasal topical antihistamines, or nasal steroids (ie, subjects who could or would not observe the washout period for these prohibited medications);
  • had an upper respiratory tract or sinus infection that required antibiotic therapy with the last dose within 14 days prior to Screening, or had a viral upper respiratory infection within 7 days prior to Screening;
  • had asthma, unless their symptoms could be controlled by a short-acting inhaled Beta2-agonist used on an "as needed" basis;
  • were on immunotherapy, unless they were on a stable maintenance schedule prior to screening. The dose of immunotherapy should remain constant and subjects could not receive immunotherapy within 24 hours prior to any visit;
  • had a history of psychosis, antagonistic personality, poor motivation, hypochondriasis, or any other emotional or intellectual problems that were likely to limit the validity of consent to participate in the study;
  • had a history of non-compliance with medications or treatment protocols;
  • had any clinically significant deviation from normal in the physical examination that, in the Investigator's judgment, may have interfered with the study evaluations or affect subject safety;
  • had any clinically significant metabolic, cardiovascular, immunologic, neurologic, hematologic, gastrointestinal, cerebrovascular, or respiratory disease, or any other disorder which, in the judgment of the Investigator, might interfere with the study evaluations or affect subject safety;
  • had liver or renal impairment.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
The primary efficacy measure was the preference rates calculated from subject comparative evaluation.
Time Frame: 1 day after the last treatment period (Visit 5)
1 day after the last treatment period (Visit 5)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Subject Non-Comparative Evaluation and subject Response to Therapy
Time Frame: 1 day after the end of each 7-day treatment period (Visit 3 and Visit 5)
1 day after the end of each 7-day treatment period (Visit 3 and Visit 5)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
