Study Arms:
- Short ragweed pollen allergen extract (Type: EXPERIMENTAL): Participants receive one sublingual tablet containing 12 units of Ambrosia artemisiifolia major allergen number 1 (Amb a 1-U), once daily (QD) for up to 35 weeks. Participants may use study-provided rescue medication(s) as needed to treat rhinoconjunctivitis symptoms.
- Placebo (Type: PLACEBO_COMPARATOR): Participants receive one placebo sublingual tablet, QD for up to 35 weeks. Participants may use study-provided rescue medication(s) as needed to treat rhinoconjunctivitis symptoms.
