What is being measured

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

  1. Change from Baseline Symptoms-Medication score at 1,3,6,12,18, and 24 months

    Patients were provided a diary to score the severity of their symptoms and the use of rescue medication during 4 consecutive weeks.

    Nasal symptoms of rhinorrhea, nasal congestion, sneezing, nasal itching, and ocular symptoms were recorded using a 4-point categorical scale from 0 to 3 (0: no symptoms, 1:mild, 2:moderate; 3:severe).

    The use of rescue medication was recorded in the patient diary according to the following score:

    Oral antihistamines (1 tablet = 1 point); intranasal corticosteroids (400mcg/day of beclometasone or equivalent = 1.4 points); and ocular antihistamines (1 dose = 1 point).

    Measured: Baseline, month 1,3,6,12,18, and 24

Secondary outcomes (6)
  1. Change from Baseline response skin prick-test at 1,3,6,12,18, and 24 months

    Measured: Baseline, month 1,3,6,12,18, and 24

  2. Change from Baseline response to intradermal test at 1,3,6,12 and 24 months

    Measured: Baseline, month 1,3,6,12,18, and 24

  3. Change from Baseline flow cytometry study at 1,3,6,12,18, and 24 months

    Measured: Baseline, month 1,3,6,12,18, and 24

  4. Change from Baseline determination of tryptase, eosinophilic cationic protein, IgG, IgG4 and specific D. pteronyssinus-IgE by Immunoassay at 1,3,6,12,18, and 24 months

    Measured: Baseline, month 1,3,6,12,18 and 24

  5. Change from Baseline response to nasal allergen provocation test with Dermatophagoides pteronyssinus at 1,3,6,12,18 and 24 months

    Measured: Baseline, month 1,3,6,12,18 and 24

  6. Adverse event

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pangramin Plus D. pteronyssinus in people with Local Allergic Rhinitis, run by Miguel Blanca Gomez at 1 site in Spain.

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 6 inclusion and 9 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 31 Mar 2016. 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 Spain. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Change from Baseline Symptoms-Medication score at 1,3,6,12,18, and 24 months (time frame: Baseline, month 1,3,6,12,18, and 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02123316, which also lists 1 linked publication.

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 31 Mar 2016.
