AZ heard pitches from multiple agencies in early December before picking Edelman, an agency it already works with on a number of fronts.
Michele Meeker, associate director of respiratory corporate affairs, confirmed the selection, but declined further elaboration.
"We're delighted to be awarded the respiratory franchise," said Julianna Richter, the account's global client relationship manager at Edelman. "This will build nicely on the other work we've been doing with [AZ] over the years."
AZ's respiratory franchise includes products used to manage asthma and chronic obstructive pulmonary disease, such as Accolate, Oxis, and Symbicort.
