Changes in Internet Search Behavior After a Direct-to-Consumer Advertising Campaign for Faricimab-svoa

Purpose: To analyze changes in Google search volume after US Food and Drug Administration (FDA) approval and initiation of a direct-to-consumer marketing campaign for faricimab-svoa. Methods: Google Trends data between December 26, 2021, and June 17, 2023, were downloaded and searched for terms prominently featured in the marketing campaign, including "wet AMD", "diabetic macular edema", "Vabysmo", and "faricimab-svoa". Data were standardized to the week and the term with the highest search volume, resulting in weekly relative search volumes for each term. The mean relative search volume and percentage change in relative search volume were calculated for the time periods of interest. Results: The direct-to-consumer campaign was associated with an increase in relative search volume in the first month for the terms "Vabysmo" (2.5% to 18.0%) and "wet AMD" (3.0% to 77.3%) and was sustained in the second month (P < .01). No significant changes in relative search volume were seen for the terms "diabetic macular edema" or "faricimab-svoa". After FDA approval, "Vabysmo" had the only significant increase in relative search volume (0.3% to 2.8%; P = .02). Conclusions: A direct-to-consumer advertising campaign for faricimab-svoa was associated with a surge in Google search volume of 620% and 2475% for "Vabysmo" and "wet AMD," respectively (P < .01), without a corresponding increase for "diabetic macular edema". Although FDA approval was associated with an increase in search volume for "Vabysmo" (P = .02), the marketing campaign was more influential at driving internet search behavior.
