About this study

Official title: Comparison of the Efficacy and the Safety of Different Schedules of Administration of Sub-lingual Immunotherapy in Patients With Ragweed Pollinosis: a Phase III Randomized and Controlled Clinical Study

The dose and the mode of administration of sublingual therapy remain open questions to determine the efficacy and safety of this desensitization therapy, the main purpose of this study is to evaluate if different routes of administration (oral-vestibular vs. sublingual) and a maximum dose of allergen administered are able to determine a different effect or a different incidence of side effects of the therapy in a group of patients with rhinoconjunctivitis and/or asthma due to ragweed

Read the detailed description

Version 1 16/02/2011 The allergen-specific immunotherapy represents an important therapeutic option for the treatment of allergic respiratory diseases. Its clinical efficacy is well demonstrated, although the mechanism of action is still under study.

The main purpose of immunotherapy is to induce an allergen-specific tolerance so that the natural exposure to the allergen does not cause clinical symptoms.

The clinical efficacy of standard subcutaneous immunotherapy (SCIT) is known. A meta-analysis Cochrane on the clinical efficacy of SCIT in allergic rhinitis 51 double-blind studies with a total 2871 patients) demonstrated a reduction in symptoms in 73% of patients and a reduction in the use of drugs in 57%.

Other studies also show that SCIT was effective in the long term (at least 3-5 years of suspension) reduces sensitization to new allergens, prevents progression of allergic rhinitis in asthma and significantly improves the symptoms of asthma, hyper- bronchial reactivity and the use of asthma medications.

Sublingual immunotherapy (SLIT) represents an effective alternative route of administration of vaccine therapy with an allergic profile security than the SCIT.

What is being measured

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

  1. To evaluate the percentage of CD14-PDL-1-IL10 + circulating allergen-specific (ragweed) in pre-seasonal SLIT vs oral-vestibular regimen and in pre-seasonal regimen of SLIT at 400 STU/dose vs 200 STU

    Measured: 3 months

Secondary outcomes (4)
  1. Evaluation of clinical efficacy (as assessed by symptom score and use of symptomatic drugs) among patients treated with sublingual vaccine by vestibular compared to those treated sublingually

    Measured: 3 months

  2. Evaluation of clinical efficacy (as assessed by symptom score and use of symptomatic drugs) among patients treated with sublingual vaccine dose doubled compared to those treated with standard dose

    Measured: 3 months

  3. Evaluation of the safety and tolerability (as assessed by data collection form of local and systemic adverse events) among patients treated with sublingual vaccine in oral/vestibular administration compared to those treated sublingually

    Measured: 3 months

  4. Assessment of safety and tolerability (assessed using data forms of local and systemic adverse events) among patients treated with sublingual vaccine dose doubled compared to those treated with standard dose

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Slit One and Slit One ragweed in people with Pollen Allergy, run by ASST Fatebenefratelli Sacco at 1 site in Italy.

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 4 inclusion and 5 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: finished, as of the sponsor's last update on 5 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To evaluate the percentage of CD14-PDL-1-IL10 + circulating allergen-specific (ragweed) in pre-seasonal SLIT vs oral-vestibular regimen and in pre-seasonal regimen of SLIT at 400 STU/dose vs 200 STU (time frame: 3 months). 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 5 Jan 2012.
