RE: BLA 761070 ® FASENRA (benralizumab) injection, for subcutaneous use MA 1150

Dear Dr. Kissen:

The U.S. Food and Drug Administration (FDA) has reviewed the promotional communication, a direct-to-consumer television advertisement (TV ad), titled “FASENRA TV 30 Frisbee” (US - ® 94786) for FASENRA (benralizumab) injection, for subcutaneous use (Fasenra) submitted by AstraZeneca Pharmaceuticals LP (AstraZeneca) under cover of Form FDA 2253. FDA has determined that the TV ad is false or misleading. Thus, the TV ad misbrands Fasenra and makes the distribution of the drug in violation of the Federal Food, Drug, and Cosmetic Act (FD&C Act).

The beginning of the TV ad shows a social media post comprising an image of a woman sitting at home in conjunction with the on-screen text, “ STUCK AT HOME WITH ASTHMA. IT’S RUFF ” (emphasis original), presented as a meme. The woman then stands up and walks out of the post, pulled by a man into an adjacent post featuring the man and another friend having fun at a park. Concurrent with these presentations is the voice-over claim, “Asthma. Does it have you missing out on what you love, with who you love? Get back to better breathing with FASENRA. . . .” Subsequently, the woman is shown laughing with her two friends and playing frisbee with her dog at the park. At the end of the TV ad, the woman is shown taking a selfie with her dog before the scene becomes a social media post with “likes” popping up in real time from people viewing the post.

The totality of these claims and presentations misleadingly suggests that Fasenra provides greater benefits to patients ages 6 years and older with severe asthma, and with an eosinophilic phenotype than has been demonstrated. Specifically, the compelling before-and - after presentations imply an improvement in social and emotional functioning. Before Fasenra treatment, the woman is described and presented as ”stuck at home,” and going through a “ruff” time. In contrast, after Fasenra treatment, she is portrayed as someone with an active social life, involving spending time with her friends and dog at the park, that is captured on social media as a photo garnering numerous “likes.” While Fasenra has been shown to improve the total Asthma Quality of Life Questionnaire for 12 Years and Older (AQLQ(S)+12) responder rate compared to placebo, the clinical studies for Fasenra were not designed to

measure the impact of treatment on individual items of the instrument, including those related to social and emotional functioning. Therefore, an improvement in the total AQLQ(S)+12 score does not necessarily correlate with a positive effect on individual components of the score.

The TV ad is misleading because it fails to include material information in the major statement about the advertised drug in the manner required for TV ads for human prescription drugs. Specifically, information regarding hypersensitivity reactions is included only in the SUPERs. The TV ad fails to communicate in the audio that patients should tell their healthcare provider or get emergency help right away if they have symptoms of an allergic reaction, as conveyed in the Patient Package Insert for Fasenra.

The major statement includes presentations where the verbatim complete transcript or verbatim key terms or phrases from the corresponding audio do not appear in dual modality, along with presentations where there is information in the SUPERs that is not from the corresponding audio. Therefore, the TV ad is misleading because it fails to present the major statement concurrently using both audio and text (dual modality).
