SUPPLEMENTARY INFORMATION: In compliance with 44 U.S.C. 3507, FDA has 
submitted the following proposed collection of information to OMB for 
review and clearance. Study of Clinical Efficacy Information in 
Professional Labeling and Direct-to-Consumer (DTC)
    Print Advertisements for Prescription Drug--(OMB Control Number 
0910-New)
    Section 1701(a)(4) of the Public Health Service Act (42 U.S.C. 
300u(a)(4)) authorizes FDA to conduct research relating to health 
information. Section 903(b)(2)(c) of the Federal Food, Drug, and 
Cosmetic Act (FD&C Act) (21 U.S.C. 393(b)(2)(c)) authorizes FDA to 
conduct research relating to drugs and other FDA-regulated products in 
carrying out the provisions of the FD&C Act.
    FDA regulations require that an advertisement that makes claims 
about a prescription drug include a ``fair balance'' of information 
about the benefits and risks of the advertised product, in terms of 
both content and presentation (21 CFR 202.1(e)(5)(ii)). In past 
research FDA has focused primarily on the risk component of the risk-
benefit ratio. In the interest of thoroughly exploring the issue of 
fair balance, however, the presentation of effectiveness, or benefit, 
information is equally important.
    The FD&C Act requires that manufacturers, packers, and distributors 
(sponsors) who advertise prescription human and animal drugs, including 
biological products for humans, disclose in advertisements certain 
information about the advertised product's uses and risks.\1\ By its 
nature, the presentation of this risk information is likely to evoke 
active trade-offs by consumers, i.e., comparisons with the perceived 
risks of not taking treatment, and comparisons with the perceived 
benefits of taking a treatment.\2\ Since FDA has an interest in 
fostering safe and proper use of prescription drugs, an activity that 
engages both risks and benefits, an in-depth understanding of 
consumers' processing of this information is central to this regulatory 
task.
---------------------------------------------------------------------------

    \1\ For prescription drugs and biologics, the FD&C Act requires 
advertisements to contain ``information in brief summary relating to 
side effects, contraindications, and effectiveness'' (21 U.S.C. 
352(n)).
    \2\ See Schwartz, L., S. Woloshin, W. Black, et al., ``The Role 
of Numeracy in Understanding the Benefit of Screening Mammography,'' 
Annals of Internal Medicine, 127(11), 966-72, 1997.
---------------------------------------------------------------------------

    Research and guidance to sponsors on how to present benefit and 
efficacy information in prescription drug advertisements is limited. 
For example, ``benefit claims,'' broadly defined, appearing in 
advertisements are often presented in general language that does not 
inform patients of the likelihood of efficacy and are often simply 
variants of an ``intended use'' statement. In a content analysis of DTC 
advertising,\3\ the researchers classified the ``promotional 
techniques'' used in the advertisements. Emotional appeals were 
observed in 67 percent of the ads while vague and qualitative benefit 
terminology was found in 87 percent of the ads. Only 9 percent 
contained data. For risk information, however, half the advertisements 
used data to describe side-effects, typically with lists of side-
effects that generally occurred infrequently.

Advertisements for Prescription Drugs: What Are Americans Being 
Told,'' Lancet, 358, 1141-46, 2001.
---------------------------------------------------------------------------

    FDA regulations require that prescription drug advertisements that 
make (promotional) claims about a product also include risk information 
in a ``balanced'' manner (21 CFR 202.1(e)(5)(ii)), both in terms of the 
content and presentation of the information. This balance applies to 
both the front (aka ``display'') page of an advertisement, as well as 
the brief summary page. However, beyond the ``balance'' requirement 
limited guidance and research exists to direct or encourage sponsors to 
present benefit claims that are informative, specific, and reflect 
clinical effectiveness data.
    The purpose of this project is to: (1) Understand how physicians 
process clinical efficacy information and how

[[Page 75478]]

they interpret approved product label information,\4\ (2) determine 
physician preferences for alternative presentations of clinical 
efficacy information in DTC advertising, and (3) examine how different 
presentations of clinical efficacy information in DTC advertising 
affect consumers' perceptions of efficacy and safety. Specifically, we 
are interested in how physicians and consumers make risk/benefit 
assessments and particularly, how consumers make such judgments in 
response to variations in the efficacy presentations in the ``display'' 
(first) page of a DTC print ad. A particular concern is whether certain 
presentations cause consumers to form skewed perceptions or unfounded 
risk/benefit tradeoffs. Therefore, we will investigate to what extent 
consumers, when provided with efficacy information, form perceptions 
that correspond with clinically-based physicians' assessments of the 
benefits, risks, and benefit/risk tradeoffs of the same drugs. These 
studies will inform FDA's thinking regarding how manufacturers may 
provide useful and non-misleading efficacy information in DTC print 
advertisements.
---------------------------------------------------------------------------

    \4\ As part of this effort, a qualitative mental models 
procedure was completed that helped us determine how physicians 
think about the efficacy of potential pharmaceutical options (OMB 
control no. 0910-0649).
---------------------------------------------------------------------------

Design Overview

    This study will be conducted in two concurrent, independent parts. 
The first part will involve 2,500 consumers in an experimental 
examination of variations of the display page of print DTC ads for two 
fictitious drugs, closely approximating existing drugs for overactive 
bladder (OAB) and benign prostatic hyperplasia (BPH). In the second 
part, 600 general practitioners will review and evaluate a fictitious 
``approved'' label for the same conditions. This design will allow us 
to compare consumers' perceptions of efficacy with a more objective 
measure of the true efficacy of the drug as measured by physician 
perceptions of clinical efficacy from labeling.
    Consumer experiment. In this part of the study, women who have been 
diagnosed with or are at risk for OAB (self-designated based on 
relevant symptoms) will be recruited and will view one version of a DTC 
ad for a drug to treat OAB. Men who have been diagnosed with or are at 
risk for BPH (self-designated based on relevant symptoms) will be 
recruited and will view one version of a DTC ad for a drug to treat 
BPH. Although the two conditions are somewhat specific to gender (men 
can suffer from OAB but it is much more prevalent in women), they share 
many of the same symptoms and characteristics. These medical conditions 
afford us the ability to maintain various realistic manipulations of 
placebo level and type of claim, as explained below. The graphical 
elements and construction of the two ads will be comparable yet still 
realistic.
    Consumers will be randomly assigned to see 1 of 12 DTC print ads 
within their respective medical condition and will answer questions 
about the effectiveness and safety of the fictitious drug advertised in 
them. These twelve experimental conditions will be created by examining 
three independent variables in the following manner: Type of claim (2 
levels: Treatment, prevention), placebo rate (3 levels: High, low, 
none), and framing (2 levels: Single, mixed). Please note that the 
numbers describing efficacy seen in the following table are for 
illustration only. Actual numbers used will be determined by 
pretesting.

    We will investigate variations of numerical presentation in two 
different types of claims: treatment and prevention. Treatment claims 
usually involve symptoms that may be alleviated by taking a given 
prescription drug. This type of claim is directly observable and 
somewhat testable by patients. If bothersome symptoms do not go away, a 
patient can return to the healthcare provider with this information and 
pursue additional options for treatment. In general, drugs that treat 
symptoms typically show substantial percentages of people who 
experience relief.
    Prevention claims are important but due to their long-term nature, 
potentially harder to communicate. A drug that prevents a negative 
future event may not alleviate any symptoms

[[Page 75480]]

at all. Patients may feel no benefit from the drug and must trust their 
healthcare provider and the data, as much as they can process it, that 
the drug is providing a positive benefit for them. The nature of these 
claims is such that the event being prevented is relatively rare, and 
thus the numbers used to describe them are often very small. For 
example, a cholesterol drug that reduces the risk of heart attack from 
3 out of 100 to 2 out of 100 may not seem objectively large, but has 
enormous consequences for millions of people and the healthcare system 
in general. We chose to test this type of claim to determine whether 
consumers are sensitive to the magnitude of the benefit in these 
clinically meaningful but objectively small and usually asymptomatic 
outcomes. While we will examine the current issues in both treatment 
and prevention claims, we do not intend to make comparisons between the 
two.
    The second variable of interest is communication of a placebo rate. 
Three levels will be examined. In addition to testing a control 
condition with no placebo information, we will utilize a high and low 
placebo rate to better understand if and how consumers use placebo 
information. We see three possibilities: (1) People use placebo numbers 
correctly, such that the low placebo group demonstrates higher 
perceived efficacy than the high placebo group; (2) people use the 
placebo numbers as a peripheral cue to mean ``science'' so there are no 
differences between high and low placebo groups on perceived efficacy 
but both are higher than the no placebo group; and (3) people do not 
find the numbers meaningful or cannot process them, so the high and low 
groups do not differ from one another and they do not differ from the 
no placebo group. In an attempt to make our claims as realistic as 
possible, we will maintain fairly low rates of prevention in the 
prevention conditions. For this reason, in addition to the 12 cells in 
the table previously illustrated in this document, we will also have an 
additional control cell in which the effectiveness rates are quite 
high--higher than could reasonably be expected but high enough to be 
objectively noticeable (e.g., risk of bladder cancer on Drug X, 4/100; 
risk of bladder cancer on placebo, 15/100). This additional condition 
will provide confidence that our research manipulations are operating 
as we expect.
    Finally, we will examine the addition of mixed framing to the 
traditional use of a single positive frame in a DTC ad. Mixed framing 
provides the number of people who benefited and the number of people 
who did not benefit, whereas positive framing provides only the number 
of people who benefited. Only a few studies have actually measured this 
mixed approach \5\ although risk communication guides recommend the use 
of mixed framing to create more accurate perceptions.\6\ Although a 
completely balanced design would also include a negative framing 
condition (which would provide only the number of people who did not 
benefit), we feel it is unrealistic to create an ad that would suggest, 
for example, that ``Drug X did not work for 70 percent of people in 
clinical trials,'' so we have chosen not to include negative framing in 
our investigation.

    In this part of the project, we are most interested in consumers' 
perceived efficacy and safety, which we can then compare with ratings 
physicians will provide based on the prescribing information, described 
in the next section. We will also ask consumers questions to measure 
their accuracy with regard to claims, their recall of the information 
in the ad, and demographic questions that may influence their 
responses, such as knowledge about their medical condition and their 
level of numeracy.
    Physician Study. Six hundred general practitioners \7\ will 
participate in an Internet survey lasting no longer than 20 minutes. 
They will complete two tasks during this time. In the first task, they 
will evaluate a prescription drug label (also known as the prescribing 
information, written for healthcare practitioners) for one of the two 
fictitious drugs described in the consumer study below. To provide a 
match for the variations of information in the DTC ads the consumers 
will observe, physicians will be randomly assigned to see prescribing 
information that varies in terms of claim type, placebo rates in 
clinical trials, and the medical condition the drug treats (OAB or 
BPH).
---------------------------------------------------------------------------

    \7\ Including internists, general practitioners, and family 
practitioners.
---------------------------------------------------------------------------

    As part of this task, we will obtain timing and sequence 
information on which sections of the label physicians examine. This 
will enable us to have a deeper understanding of physicians' processing 
of the prescribing information. We are not aware of existing literature 
on this topic. Additionally, physicians will answer questions about the 
efficacy and safety of the drug and quantitative questions about the 
benefit shown in the clinical studies (as described in the label). 
These questions have been designed such that they can be reasonably 
compared with the responses of consumers who will answer the same 
questions after viewing a corresponding DTC ad.
    In the second task, physicians will see four versions of a print 
DTC ad for a fictitious product for high cholesterol and will rank the 
ads in order of how representative of the clinical data as the 
physicians know it the ads are and how useful they believe the ads 
would be for their patients.\8\ The four versions will be selected to 
mirror the versions of the OAB/BPH drug that consumers will see in the 
consumer experiment (i.e., low placebo, frame).
---------------------------------------------------------------------------

    \8\ To reduce burden, the physician sample will be split in this 
task, so that half of the physicians see the four ad versions with 
treatment claims and the other half see the four ad versions with 
prevention claims. Type of claim is described in greater detail in 
the consumer experiment section.
---------------------------------------------------------------------------

    Thus, this research will provide us with a rich data set in order 
to address several questions: (1) How physicians process clinical 
efficacy information and how they use approved product label 
information, (2) how physicians' interpretations of clinical efficacy 
information relate to their preferences for alternative DTC ad 
presentations, and (3) which variations of information in DTC ads bring 
consumers closer to or farther away from the conclusions of the 
physicians regarding the same drugs.
    FDA estimates the burden of this collection of information as 
follows:
    The total respondent sample for this data collection is 3,400. We 
estimate the response burden to be 20 minutes in the first part and 15 
minutes in the second part, for a burden of 906 hours.
    In the Federal Register of June 16, 2010 (75 FR 34142), FDA 
published a 60-day notice requesting public comment on the proposed 
collection of information. No comments were received on the paperwork 
burden.
