Categories of Warning Letters • Division of Drug Marketing, Advertising and Communications (DDMAC) Warning Letters • Pharmaceutical Manufacturing Facility Inspection Warning Letters • Nonclinical and Bioequivalence Studies Inspection Warning Letters
DDMAC Frequently Cited Violations • Minimization of Risk Information • Omission or Inappropriate Display of Risk Information • Unsubstantiated Efficacy Claims • Unsubstantiated Superiority Claims • Failure to Disclose or Misleading Communication of Drug Indication • Failure to Submit for Review • Takes backseat to concerns over safety/ accuracy of the information advertised
Full Product Versus Reminder Ads • Full Product Ad must contain a true statement of risk and warning information related to side effects, contraindications and effectiveness. • Reminder Ad does not need to include risk or warning information. • Problem – When the pharmaceutical company intends an ad to be a reminder ad, but the DDMAC concludes it is a full product ad. • Outcome – Warning Letter cites company for failure to provide risk and warning information.
Full Product Versus Reminder Ad Example • A Celebrex TV ad depicts a woman playing a guitar accompanied by the statement “With Celebrex, I will play the long version.” • DDMAC concluded it was a full product ad because the statement accompanied by the image made representations about the drug’s indication and benefits. • The company was cited for failure to include risk, side-effect and contraindication information.
Risk Information is a Primary Concern • Ensuring thorough reporting of risk information is a primary concern to the DDMAC because “failure to present this important risk information may lead to serious health risks ….” • Omission of risks raises serious public health and safety concerns.
Omission or Inappropriate Display of Risk Information • Companies were cited for: • Totally omitting risk information • Mentioning some risks, but omitting others • Advising the viewer to seek risk information at a separate source, but totally omitting risk information from the ad • Linking to or accompanying the main ad with warning or prescribing information
Minimization of Risk Information • Companies were cited for: • Showing distracting imagery or voice-overs while displaying risk information • Failing to flag or headline risk information as important • Using broad or imprecise language to downplay risks • Overstating safety by ignoring or misrepresenting data • Providing incomplete or ambiguous contraindication lists
Unsubstantiated Efficacy Claims • Companies were cited for: • Suggesting a product can have certain effects without providing research to support the claims • Example – Claiming the product provides “total relief” without data to support the claim of total relief • Example – Stating “results may vary” or “not everyone will respond” is insufficient • Suggesting the product can be used to treat patients for whom it is not recommended • Relying on uncontrolled or retrospective analysis from failed studies
UnsubstantiatedSuperiorityClaims • Superiority Claims must be supported by “substantial evidence obtained from adequate and well-controlled head-to-head clinical trial(s).” • In order to claim superiority to all similar products, the company must have substantial comparative studies to support the claim.
Unsubstantiated Superiority Claims • Companies were cited for: • Comparative claims with no clinical support • Comparative claims based on indirect comparisons or data from invalid studies • Selectively advertising data from comparison studies to make it appear their product was superior when in fact one or more comparison product was superior
Unsubstantiated Superiority Claims • Companies were cited for: • Posing open-ended questions and not providing a complete comparison • Calling product “breakthrough” or “best” without substantial evidence of superiority • Implying other products are less effective by suggesting if the patient switches the advertised product will work • Claiming superiority to all similar products based on research only comparing to two similar products
Failure to Disclose or Misleading Communication of the Drug’s Indication • Companies were cited for: • Not stating what illness the drug was indicated to treat • Broadly characterizing the illness the drug was indicated to treat • Example – Depression medication ad was cited because the ad described depression symptoms so broadly that it did not communicate the difference between major depression and normal mood-swings • Overstating the number of patients the drug could be used to treat by not stating risks or contraindications
Less Frequently Cited Violations • Failure to disclose or misstatement of ease of drug administration • Suggesting a product was safe and effective for a use or dosage not FDA approved • Failure to provide a brief summary or take adequate steps to make the PI available • Must make PI available numerous ways: website, healthcare provider, telephone, public places, etc.
