Evaluation of the Utility of an EEC for Assessing Efficacy of SIT in Pivotal Clinical Trials

January 16, 2018 updated by: Allergopharma GmbH & Co. KG

Evaluation of the Utility of an Environmental Exposure Chamber (EEC) for Assessing Efficacy of Specific Immunotherapy (SIT) in Pivotal Clinical Trials

The study will explore how allergy symptoms experienced during the grass pollen season compare to symptoms experienced in the Environmental Exposure Chamber (EEC).

There are 2 treatments in this study. Both treatments are injected under the skin. Allergovit® Grasses works by helping the body's immune system get used to grass-pollen before the grass pollen season begins which may lead to decreased sensitivity and reduced allergy symptoms during the grass season. Placebo treatment does not contain grass pollen mixture, and is not expected to reduce allergic symptoms overtime.

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

This is a Phase II trial, with a one year observational/baseline phase followed by a one year double-blind placebo-controlled, randomized, treatment phase. Approx. 137 grass pollen-allergic subjects and 20 non-allergic subjects will be enrolled in the baseline phase of the study. The primary objective of the trial is to investigate the relationship between allergy symptoms experienced by subjects (allergic and non-allergic) upon exposure to grass pollen-allergen in the EEC and the allergy symptoms experienced by subjects during the grass pollen season.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Yes

  • IgE-mediated seasonal allergic rhinitis/rhinoconjunctivitis with or without allergic asthma
  • positive skin prick test
  • specific IgE ≥ 0.70 kU/L to mixture of grass pollen allergens

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.

Analysis of the relationship between different methods of measurement of efficacy of SIT.

The AUC of the Total Symptom Score (TSS) as primary endpoint assessed in an EEC after preseasonal treatment
