Who may be able to join

  • Prior to study specific examinations the patient and if applicable both legal guardians has to give his/her written informed consent
  • Patients of both gender aged from 18 and 55 years
  • Patient's perception of disease activity of at least 30 mm on a 100 mm visual analogue scale (VAS)
  • FEV1 greater or equal than 80% of the expected value, and if not, improvement of FEV1 greater than 12% after bronchodilation
  • Patients have to suffer from allergic complaints (rhinitis and/or rhinoconjunctivitis with or without mild intermittent allergic asthma) caused by clinical sensitization against Olea europaea pollen. The IgE mediated sensitization has to be verified by:
  • Suggestive medical history

  • Positive skin prick test (SPT) to grass Olea pollen resulting in a wheal diameter of at least 3 mm.

Who cannot join

  • History of significant clinical manifestations of allergy as a result of sensitization against weed pollen allergens and perennial (e.g. house dust mite.
  • Participation in an immunotherapy with comparable extracts within the last five years.
  • Treatment with β-blocker
  • Any disease which prohibits the use of adrenaline (e.g. hyperthyroidism)
  • Cardiovascular insufficiency or any severe or unstable pulmonary, or endocrine disease; clinically significant renal or hepatic disease or dysfunction; hematologic disorder; any other clinically significant medical condition that could increase the risk to the study participant

About this study

Official title: Multicenter, Randomised, Double-blind Placebo-controlled, Subcutaneous Immunotherapy Clinical Trial With Depigmented and Polymerized Allergen Extract of Olea Europaea Pollen in Patients With Hypersensitivity to Olea Pollen

The objective of this trial is to assess the clinical efficacy of a modified allergen extract of Olea europaea pollen in the treatment of patients affected by allergic rhinitis/rhinoconjunctivitis (with or without episodic asthma) induced by hypersensitivity to olea europaea pollen, evaluating the Score regarding Symptoms and consumption of the medication.

Read the detailed description

Immunotherapy is a specific treatment for allergic diseases. Unlike conventional pharmacological treatment, immunotherapy is the only treatment that could modify the natural course of allergic disease. This is a prospective double-blind placebo-controlled study with two arms of treatment: placebo and active.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Immunotherapy with modified extract of Olea europaea pollen in people with Rhinitis or Rhinoconjunctivitis With or Without Asthma Induced by Hypersensitivity to Olea Europea Pollen, run by Laboratorios Leti, S.L. at 7 sites 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 8 inclusion and 8 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 23 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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 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?

Symptoms and medication score (time frame: 2 years). 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 23 Feb 2018.
