Galliard, which started work on a four-month contract last month, beat
Zaicom MMC, Wave and Thomson Gardiner-Caldwell Communications in a four-way pitch to secure the business.
The agency is handling opinion-leader development and seeking to boost AZ’s profile among those involved with breast-cancer care across the UK.
An agency team led by director Dr Sanjay Singhvi reports to AZ breast cancer professional relations manager Samantha Hall.
Galliard already promotes other AZ brands, such as prostate cancer treatment Casodex and cardiovascular product Atacand.
