Allevia x BMG Partnership

Hearts & Science UK

Client: Sanofi, Allevia

In 2022, Hearts & Science helped Sanofi launched Allevia

to help the 16 million UK hay fever sufferers with great success. We did this by creating the worlds most sophisticated allergy model which helped deliver one of the most successful pharmaceutical launches of all time (according to IRI data) in an overwhelming shouty category. This model informed media budgets, activation and optimisation, meaning we smashed our brand goals (establish 10% product awareness, 4% market share) and hit our 5-year business ambition in under 18 months.
