Observational Analysis of T Cell Responses to SPIREs for Multiple Allergens in Subjects With Allergy in North America

April 5, 2019 updated by: Adiga Life Sciences, Inc.

Observational, Cross-sectional Analysis of T Cell Responses to Synthetic Peptide Immuno-Regulatory Epitopes (SPIREs) for Multiple Allergens in Subjects With Allergy in North America

This is a research study intending to look at the response of a specific type of allergy cells in the blood (called T cells) to a a type of immunotherapy product known as SPIREs (Synthetic Peptide Immuno-Regulatory Epitopes), across a broad range of subjects. This is a non-interventional study in which no investigational product will be administered to any subject.

Study Overview

Status

Status

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

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.

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

Sampling Method

Non-Probability Sample

Study Population

The study population will consist of subjects aged from 18 to 65 years, with a documented history of allergy to one or more of the following: cat, short ragweed, Rye grass, or House Dust Mite.

Description

Inclusion Criteria:

  1. Male or female, aged 18-65 years.
  2. Willing and able to provide written informed consent.
  3. One year history of allergic rhinoconjunctivitis to one or more of cat, short ragweed, Rye grass, or HDM.
  4. Positive skin prick test to each allergen for which a subject has a qualifying clinical history.

Exclusion Criteria:

  1. Clinically relevant history of alcohol or drug abuse.
  2. Use of any oral or parenteral (except low dose inhaled) corticosteroids within 2 months prior to the visit or any other immunosuppressive therapy within 3 months prior to the visit.
  3. Vaccination/ inoculation within the 6 weeks prior to the first visit.
  4. A history of any significant disease or disorder (e.g. autoimmune, cardiovascular, pulmonary, gastrointestinal, liver, renal, neurological, musculoskeletal, endocrine, metabolic, neoplastic/malignant, psychiatric, major physical impairment, severe atopic dermatitis).
  5. Subjects who have taken an investigational drug within 6 weeks prior to the visit or are currently participating in any other clinical study.
  6. Recent blood donation of an amount of >100 mL.
  7. Immunotherapy within the last 5 years to any of the allergens for which a subject would otherwise be eligible on the basis of clinical history and skin prick test result.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

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
Evaluation of T cell responses to SPIREs
Time Frame: 2 years
2 years

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
Characterization of the distribution of allergen sensitivity across a broad range of common allergens
Time Frame: 2 years
2 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2015

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
June 25, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
