Arms Assigned Interventions
Placebo Comparator: Placebo
Placebo group
Biological: Placebo
Two matching placebo tablets were administered every day over 2 weeks with a 2-day break for the week-end.
Experimental: Active group
rBet v 1 tablets
Biological: rBet v 1
Two tablets (1 placebo + 1 rBet v 1 or 2 rBet v 1) were administered every day over 2 weeks with a 2-day break for the week-end. Administered doses ranged from 50 to 300 µg rBet v 1.
