Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

DEPIGOID phleum

The active treatment arm receive active phleum pollen immunotherapy (Depigoid 100% phleum). Depigmented and polymerized allergen extract of Phleum pollen for subcutaneous injection.

Group Type ACTIVE_COMPARATOR

DEPIGOID phleum

Intervention Type BIOLOGICAL

Subcutaneous Immunotherapy with modified extract of Phleum pollen.

DEPIGOID Placebo & DEPIGOID Phleum

This arm receive DEPIGOID Placebo during the first year, and DEPIGOID Phleum during the second year of study.

DEPIGOID Placebo contains the same composition as in the active DEPIGOID Phleum with the only difference being the exclusion of the phleum pollen allergen extract.
