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.

Detailed Description

Oral or intranasal antihistamines is the first line treatment for allergic rhinitis. Cetirizine is a second-generation selective antihistamine widely used in an oral formulation for the treatment of allergic rhinitis. Local administration of cetirizine has been shown to reduce symptoms after allergen challenge, and has the potential to shorten the time to onset and decrease systemic side effects. However, local irritation and nasal burning/pain has been reported after nasal administration. For the compliance of the patients taking a nasal spray, the taste and tolerance of the product is of particular importance. NLA Nasal Spray contains cetirizine in a liposomal formulation aiming to improve the tolerability. The present study aims to compare the NLA Nasal Spray with cetirizine in an aqueous formulation and placebo with regard to taste perversion and local tolerance. This will be investigated off-season in patients with seasonal allergic rhinitis after provocation with allergen.

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 to 50 years (Adult)
