Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This prospective open multi-centre non-interventional study was initiated to document the tolerability and the safety profile of the subcutaneous allergen-specific immunotherapy with Acarovac® in house dust mite allergic patients in routine medical care.

During the up-dosing phase with Acarovac®, patients will receive 4 injections in 1-2 week intervals with increasing allergen amount up to the individual maximum tolerable dose. After reaching the individual maximum tolerable dose patients will receive one maintenance dose in a 4 - 8 week interval.

Data on tolerability are documented by the physicians.

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

1 year and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Adults, adolescents and children from the age of 5 on, who suffer from perenial allergic rhinoconjunctivitis causued by house dust mites.

Acarovac Hausstaubmilbe

This prospective open multi-centre non-interventional study was initiated to document the tolerability and the safety profile of the subcutaneous allergen-specific immunotherapy with Acarovac in house dust mite allergic patients (children and adults) in routine medical care.

During the up-dosing phase with Acarovac, patients will receive 4 injections in 1-2 week intervals with increasing allergen amount up to the individual maximum tolerable dose. After reaching the individual maximum tolerable dose patients will receive one maintenance dose in a 4 - 8 week interval.

Drug: Acarovac
House dust mite sensitized Patients receive increasing doses of subcutaneous immunotherapy with Acarovac. During the up-dosing phase, patients will receive 4 injections in 1-2 week intervals with increasing allergen amount up to the individual maximum tolerable dose. After reaching the individual maximum tolerable dose patients will receive one maintenance dose in a 4 - 8 week interval.

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
Numbers of treatment-related local and systemic reactions following SCIT administration
Time Frame: over the overall duration of the study

Tolerability and safety will be assessed by the frequency and intensity of local reactions at the injection site (wheal size 5-10 cm, > 10 cm ) and systemic reactions (skin, airways, others) through study completion.

The study covers the four injections of the up-dosing phase and one injection of the maintenance phase of the immunotherapy course.
over the overall duration of the study

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
Safety and Tolerability - frequency and intensity of adverse events
Time Frame: over the overall duration of the study
Frequency and intensity of adverse events
over the overall duration of the study
Safety and Tolerability - local reactions at injection site
Time Frame: over the overall duration of the study
Frequency and intensity of local reactions at the injection site (wheal size 5-10 cm, > 10 cm )
over the overall duration of the study
Safety and Tolerability - Number of systemic reactions
Time Frame: over the overall duration of the study

over the overall duration of the study
Changes in rhinoconjunctivitis score
Time Frame: baseline and 3-6 month, depending on the intervals between the injections and the applied up-dosing scheme
The rhinoconjunctivitis score combines rhinitis symptom intensity and conjunctivitis symptom intensity and will be assessed retrospectively and after the course of treatment

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2017

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.
