Efficacy and Safety of Intraseasonal Specific Immunotherapy With Depiquick® Birch (INSIDE)

March 20, 2017 updated by: Novartis

A Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Intraseasonal Specific Short-term Immunotherapy With Depigmented Glutaraldehyde Polymerized Birch Pollen Allergenic Extract (Depiquick® Birch) in Patients With Allergic Rhinitis and/or Rhinoconjunctivitis With or Without Intermittent Asthma

This study will assess efficacy and safety of intraseasonal specific short-term immunotherapy with Depiquick® Birch in patients with allergic rhinitis and or rhinoconjunctivitis with or without intermittent asthma that have a clinical relevant IgE-mediated allergic sensitization against birch pollen. The term "intraseasonal" means that patients will start with immunotherapy treatment during the birch pollen season, i.e. when the already experience allergic symptoms.

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

12 years to 70 years (Child, Adult, Older Adult)

Exclusion criteria:

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.
Experimental: Depiquick® Birch
At the screening visit (Visit 1), patients will be instructed how to complete the eDiary. Eligible patients will return for visit 2 as soon as they experience significant allergic symptoms. Significant allergic symptoms are defined by a symptom score ≥ 2. If the patients' eligibility has been confirmed according to inclusion/exclusion criteria checklist, randomization to one of the 2 treatment arms will be conducted. Patients will receive two consecutive subcutaneous injections of study medication (0,2 and 0,3 ml) with a time lag of ≥ 30 minutes. Patients return to the study site in weekly intervals for visit 3, visit 4, visit 5, visit 6, and visit 7 to receive study medication injections (0,5 ml each). If treatment is completed before the end of the tree pollen season, patients will be followed-up by telephone calls every 4 weeks until the end of the tree pollen season. The study completion visit will take place 4 weeks after the end of the tree pollen season.

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
Measure Description
Time Frame
Combined Symptom and Medication Score (SMS)
Time Frame: From the start of treatment until the end of the relevant pollen exposition time.
The SMS represents the sum of the mean daily symptom severity score plus the mean daily rescue medication score. The symptom severity score is defined as the mean of the daily symptom severity scores during the pollen season. The rescue medication score is defined as the mean of the daily rescue medication scores during the pollen season. A lower score indicates an improvement in the allergic condition. Minimum score of the SMS is "0", maximum score is dependent on intake of rescue medication.
From the start of treatment until the end of the relevant pollen exposition time.

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
Measure Description
Time Frame
Combined Symptom and Medication Score (SMS)
Time Frame: date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months
The SMS represents the sum of the mean daily symptom severity score plus the mean daily rescue medication score. The symptom severity score is defined as the mean of the daily symptom severity scores during the pollen season. The overall severity rhinitis/rhinoconjunctivitis (including nasal itching, sneezing, rhinorrhea, nasal obstruction, ocular itching/grittiness/redness, and ocular tearing) and asthma (including chest tightness, shortness of breath, cough, wheezing) will be evaluated by the patient daily
date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months
Onset of action (patient's assessment)
Time Frame: date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months
Patients will document the point in time when they experience onset of action of the therapy by answering the question "Do you have the feeling that your allergy symptoms are better or less due to SIT today?" with "Yes" or "No".
date of randomization until 4 weeks after the end of the birch pollen season 2012, assessed up to 5 months
Rhinoconjunctivitis Quality of Life questionnaire (RQLQ)
Time Frame: Visits 2, 4, 6, and 7
The RQLQ is a 28-item disease specific questionnaire designed to measure functional impairments that are most important to patients with rhinitis/rhinoconjunctivitis (Juniper and Guyatt 1991). It consists of 7 domains (activities, sleep, common complaints, practical problems, nasal symptoms, ocular symptoms, and emotions).
Visits 2, 4, 6, and 7

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
