Tyrosine Allergoid Paediatric and Adult Study

January 28, 2026 updated by: Allergy Therapeutics

A Long-term, Prospective, Open, Multi-centre, Non-interventional Study to Evaluate the Effectiveness After Treatment With TA Bäume Top (Trees) and TA Gräser Top (Grass) Following a Perennial Posology in Children and Adults, as Well as Proofing the Non-inferiority of Children Compared to Adults

The primary objective of this 5-year study is to demonstrate non-inferiority of children compared to adults by exploring long-term effectiveness after treatment with TA Bäume (trees) and TA Gräser (grass) following a perennial posology.

Study Overview

Status

Active, not recruiting

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

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

5 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Adults, adolescents and children from the age of 5 on, who are going to be treated with TA Bäume or TA Gräser.

Description

Inclusion Criteria:

  • Patients from 5 years of age who are treated with TA Gräser top or TA Bäume top due to rhinitis, conjunctivitis and/or mild to moderate bronchial asthma, which are caused by an IgE-mediated allergy to grass and rye pollen or birch, alder and hazel pollen according to the respective SmPC.
  • Patients will only be included in this study after the decision on the treatment has been made.

Exclusion Criteria:

  • History of allergen-specific immunotherapy (SIT) for trees or grass within the last 5 years
  • If it´s intended to treat the patient with only a preseasonal therapy
  • A patient should also not be included in the presence of any of the conditions listed in the respective SmPC

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
change in the combined symptom medication score (CSMS)
Time Frame: once a year for 5 years
The primary endpoint is the change in the total combined symptom medication score (CSMS) during the entire study period, determined from the rhinoconjunctivitis daily symptom score (dSS) and rhinoconjunctivitis daily medication score (dMS), averaged over the respective peak pollen season
once a year for 5 years

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
rhinoconjunctivitis daily medication score
Time Frame: once a year for 5 years
the changes in use of daily anti-allergic medication needed, averaged over the respective peak pollen season
once a year for 5 years
rhinoconjunctivitis daily symptom score
Time Frame: once a year for 5 years
allergic symptoms and severity will be self-recorded by the subject in an eDiary on a daily basis during the pollen season, averaged over the respective peak pollen season
once a year for 5 years
Rhinoconjunctivitis Quality of Life
Time Frame: twice a year for 5 years
The change in quality of life as assessed by the standardised Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ(s))
twice a year for 5 years
Rhinitis Control
Time Frame: twice a year for 5 years
change in symptom control of rhinitis assessed by Rhinitis Control Assessment Test (RCAT)
twice a year for 5 years
Asthma Control
Time Frame: twice a year for 5 years
The change of asthma control in asthmatic patients assessed by the (Childhood) Asthma Control Test (C-ACT/ACT)
twice a year for 5 years
Incidence of Treatment-Emergent Adverse Events (safety and tolerability)
Time Frame: all year for 3 years
frequency and severity of Treatment-Emergent adverse events
all year for 3 years
treatment satisfaction
Time Frame: once after 3 years and once after 5 years
directly assessed by the physician (questionnaire)
