A Multicenter, Open Trial With Subcutaneous Immunotherapy (SCIT) in Patients With Rhinoconjunctivitis Sensitized to Parietaria Judaica

April 28, 2017 updated by: Roxall Medicina España S.A

A Multicenter, Open Clinical Trial With Subcutaneous Immunotherapy in Depot in Patients With Rhinoconjunctivitis Sensitized to Parietaria Judaica

The study was designed according to the draft of allergenic product regulation published by Spanish Regulatory Agency. The aim of the study is to evaluate the safety and tolerability of subcutaneous immunotherapy with Parietaria judaica pollen extract in patients with rhinoconjunctivitis with or without associated mild asthma. In addition, surrogate efficacy parameters will be evaluated: immunoglobulin level changes and skin reactivity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

Parietaria judaica is a weed widespread throughout the Mediterranean área. Prevalence of sensitization to Parietaria judaica's pollen is very high in the Mediterranean areas, reaching 41.4% among allergic patients on the Spanish Mediterranean coast.

The study has been designed as an open trial which will be conducted in 4 Spanish sites.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  2. Patients with severe asthma or forzed expiratoy volumen in 1 second FEV1< 70% even if the are pharmacologically controlled .
  3. Patients with: immunological, cardiac, renal or hepatic illnesses or any other medical condition that the investigator deems relevant so as to interfere with the study.
  4. Patients with a previous history of anaphylaxis
  5. Patients with chronic urticaria,
  6. Patients with moderate to severe atopic dermatitis

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
Number and severity of adverse reactions as a measure of Safety and tolerability
Time Frame: across 17 weeks treatment period
across 17 weeks treatment period

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
Immunoglobulin changes from baseline
Time Frame: At baseline and 1 week after last administered dose
