Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this trial is to assess the clinical impact of T502 treatment administered subcutaneously to patients with birch pollen-induced allergic rhinoconjunctivitis. - The effect will be assessed by comparing the symptoms and the medication need in actively treated and placebo patients during the peak birch pollen season.;Secondary Objective: The secondary objectives are: • To assess the safety and clinical tolerability of T502 treatment • To assess the impact of T502 on the immunological status of the patients in comparison to placebo • To assess the clinical impact of T502 in comparison to placebo with regard to health-related quality of life. ;Primary end point(s): The clinical impact of T502 treatment will be assessed by comparing the Combined Symptom and Medication Score (CSMS) over the peak birch pollen season 2022 between the placebo and the active treatment group.;Timepoint(s) of evaluation of this end point: The Combines Symptom and Medication Score (CSMS) will be evaluated over the peak birch pollen season 2022. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Safety and clinical tolerability assessment of T502 treatment will be assessed by: - Solicited adverse events • Local reactions at the injection site (swelling and redness) • Systemic allergic reactions after administration of the investigational product. - Unsolicited adverse events and serious adverse events - Physical examinations and vital signs - Laboratory investigations (blood count, renal and liver function-related parameters) - Pulmonary function testing for asthmatic patients - Use of rescue medication during the treatment phase Clinical immunogenicity endpoints will include: - Production of birch pollen-specific immunoglobulins IgE, IgG and IgG4 Optional: - Production of Blocking Antibodies (FAB assay, assessment in some centres in Germany) Clinical impact endpoints will include: - The Combined Symptom and Medication Score (CSMS) over the entire birch pollen season 2022 - The mean daily Symptom Score (dSS) over the birch peak pollen season and the entire birch pollen season - The mean daily Medication Score (dMS) over the birch peak pollen season and the entire birch pollen season - Differences between placebo- and actively treated patients in health-related Quality of Life during the birch pollen season (V7, V8) ;Timepoint(s) of evaluation of this end point: Solicited AEs will be evaluated between V2 and V7, unsolicited AEs and SAEs between V1 and V9. Physical examinations and vital signs will be evaluated between V1 - V9. Safety laboratory investigations will be done at V1 and V7. The use of rescue medication during the treatment phase will be evaluated between V2 and V6. Immunogenicity endpoints will be measured at V 1 and V7. CSMS will be evaluated over the entire pollen season. RQLQ will be evaluated at V7 and V8. | — |
