Evaluation of Nasal Inflammatory Biomarkers

February 13, 2019 updated by: Fraunhofer-Institute of Toxicology and Experimental Medicine

Evaluation of Nasal Inflammatory Biomarkers During the Early and Late Phase Response to Nasal Volus Allergen Challenge in in Subjects With Seasonal Allergic Rhinitis (Out-of-season)

This research aims to establish a panel of inflammatory biomarkers of the early (Histamine, Tryptase, ProstaglandineD2) and late (Interleukin-4, Interleukin-5, Interleukin-6, Interleukin-13, Eotaxin, Tumor necrosis factor-a (TNF), (Macrophage Inflammatory Protein-1beta (MIP1ß)) phase response to nasal bolus allergen challenge (NAC) in subjects with out-of-season seasonal allergic rhinitis, suitable for future application in drug intervention studies of novel anti-allergy therapeutics.

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

Biomarkers will be sampled by nasal filter paper (NFP) adsorption and lavage (NLF) prior to and following NAC. Samples from initial subjects (Cohort A; n~6) will be used primarily for validation of biomarker assays in nasal filter paper eluates. Validated biomarker assays will be applied to analyze biomarker changes in a further cohort of subjects (Cohort B; n~12) with the aim of fully defining the optimum panel and sampling time points for future studies.

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 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  3. History of seasonal allergic rhinitis to grass pollen with symptoms during the 2016 and 2017 allergen season requiring treatment with anti-histamines, nasal corticosteroids or leukotriene antagonists.
  4. Absence of significant current symptoms of allergic rhinitis consistent with being out of season for their principal allergen (eg grass).
  5. Skin prick test positive for mixed grass pollen allergen at Visit 1 or within one year prior to screening.

Exclusion criteria

  1. Asthma requiring more than inhaled short-acting beta-2 agonists.
