Trial summary

Patients demonstrated allergic to corn pollen and timothy grass pollen (by allergy testing) who have undergone 1 to 2 years of subcutaneous allergen immunotherapy (SCIT) containing timothy grass extract with moderate symptomology (as documented via rhinitis symptom score surveys) will constitute the treatment group.

About this study

Official title: Corn Based Occupational Rhinitis; SCIT Efficacy Study

Patients demonstrated allergic to corn pollen and timothy grass pollen (by allergy testing) who have undergone 1 to 2 years of subcutaneous allergen immunotherapy (SCIT) containing timothy grass extract with moderate symptomology (as documented via rhinitis symptom score surveys) will constitute the treatment group. Those who previously chose not to undergo SCIT who have documented symptomology and are skin test positive to corn pollen will constitute the control group. Prospective symptom score analyses and retrospective quality of life assessments (RQLQ) will be the primary and secondary efficacy outcome measures.

Read the detailed description

Statistical assessment suggests enrollment of 20 patients into the treatment group (defined above) and an additional 20 into the control group. Patients will be matched for the level of symptomology (based on symptom score surveys) and residing/working on corn-crop farms. The premise for this study is the cross-reactivity of putative immunogenic sites between timothy grass pollen and corn pollen. based on consensus genetic sequences. Thus, the hypothesis is the use of Timothy grass extract containing immunotherapy would diminish symptomology to corn-based occupational rhinitis. Enrolled patients will have signed IRB approved consent forms and have undergone SCIT for 1 to 2 plus years (treatment group) or not undergone SCIT therapy for the same time period (control group). Potential contribution to symptom scores from other sources (e.g. Ragweed) will be analyzed by assessment of local pollen counts.Efficacy assessment will compare prospective symptom score results and retrospective quality of life survey scores between the treatment and control group responses.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • subcutaneous allergen immunotherapy (SCIT)Biological

    20 patients who (prior to study enrollment and initiation) completed more than 1 year of timothy grass SCIT vs. 20 control patients who underwent corn pollen exposure for for greater than one year during the same prestudy time interval. Efficacy will be assessed by analyses of symptom score surveys and quality of life surveys.

  • SCITBiological

    Treatment group consists of patients who completed > 1 year of SCIT while control group patients did not undergo SCIT

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Corn based Occupational Rhinitis symptom and medication score surveys

    The completed symptom and medication score surveys will be contrasted from before to after therapy and between treatment and control groups.

    Measured: prior to study enrollment patients completed more than 1 year of SCIT. Actual study is 1 day to complete surveys.

Secondary outcomes (1)
  1. Corn based Occupational Rhinitis quality of life surveys

    secondary outcome measure-completed quality of life surveys will be assessed from before to after therapy and between the treatment and control groups.

    Measured: Actual survey completions take less than 1 day.

Questions about this trial

What is this clinical trial studying?

A study testing subcutaneous allergen immunotherapy (SCIT) and SCIT in people with Rhinitis, run by United Allergy Services.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 May 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Corn based Occupational Rhinitis symptom and medication score surveys (time frame: prior to study enrollment patients completed more than 1 year of SCIT. Actual study is 1 day to complete surveys.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 May 2018.
