Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is announcing that a proposed collection of information has been submitted to the Office of Management and Budget (OMB) for emergency processing under the Paperwork Reduction Act of 1995 (the PRA). The proposed collection of information is in response to a petition for health claims for glucosamine and chondroitin sulfate. The study examines various petitioned health claims about the effect of glucosamine and chondroitin sulfate on osteoarthritis. The goal of the study is to determine if certain claims about glucosamine and/or chondroitin (the “product”) and the reduction of risk of specific outcomes related to osteoarthritis, namely joint degradation and cartilage deterioration, create misperceptions on the part of consumers about the intended use of the product.
Fax written comments on the collection of information by July 6, 2004. FDA is requesting approval of this emergency processing by July 6, 2004.
OMB is still experiencing significant delays in the regular mail, including first class and express mail, and messenger deliveries are not being accepted. To ensure that comments on the information collection are received, OMB recommends that comments be faxed to the Office of Information and Regulatory Affairs, OMB, Attn: Fumie Yokota, Desk Officer for FDA, FAX: 202-395-6974.Start Further Info

FDA is requesting emergency processing of this proposed collection of information under section 3507(j) of the PRA (44 U.S.C. 3507(j) and 5 CFR 1320.13). The information is critical to the agency's mission of regulating health claims on dietary supplements. FDA has received petitions for new health claims for glucosamine and chondroitin sulfate. Unlike traditional health claims that promote the ability of a product to reduce the risk of a particular disease, the petitioned claims promote the ability of the product to reduce the risk of a specific health outcome without mention of an associated disease.
Traditionally, a health claim states how a product will reduce the risk of contracting a particular disease. An example of this type of claim would include “Eating a diet rich in fruits and vegetables may reduce the risk of cancer.” Here, the statement clearly defines the product (fruits and vegetables), its risk-reducing effect, and the disease upon which it may be effective (cancer). The petitioned claims, however, do not employ the standard structure as traditional health claims.
The petitioned claims are designed as health claims, in that they promote the risk reducing effect of glucosamine and chondroitin sulfate. The claims neglect, however, to mention the specific disease risk, or the risk of osteoarthritis, that the product intends to reduce. Instead, the claims mention symptoms, modifiable risk factors, and surrogate endpoints of the disease. An example of these claims is “Glucosamine and chondroitin sulfate may reduce the risk of joint degradation.” The petitioned claims to be examined resemble health claims by their use of language concerning the reduction of risk. Yet they employ terminology suggestive of modifiable risk factors of the disease, which are elements not traditionally found in health claims. It is not clear how consumers will interpret these claims. The agency is concerned that the label language may cause consumers to interpret the claims in such a way that would suggest it has an effect on the disease or condition other than risk reduction.
Consumer research is needed to test consumer's perceptions of claims that promote risk reduction of contracting a symptom or a modifiable risk factor for a disease. Despite the verbiage within the claim about risk reduction, the presence of health conditions without mention of a disease may cause consumers to believe that the product will treat the health condition rather than reduce risk. If consumers disregard language concerning the reduction of risk and interpret the claim as one that promotes a treatment effect, then the claim language has created a misperception on the part of the consumer. The result is that consumer's interpret the claim as a treatment claim rather than a health claim.
FDA invites comments on: (1) Whether the proposed collection of information is necessary for the proper performance of FDA's functions, including whether the information will have practical utility; (2) the accuracy of FDA's estimate of the burden of the proposed collection of information, including the validity of the methodology and assumptions used; (3) ways to enhance the quality, utility, and clarity of the information to be collected; and (4) ways to minimize the burden of the collection of information on respondents, including through the use of automated collection techniques, when appropriate, and other forms of information technology.
Experimental Study of Petitioned Health Claims on Glucosamine and Chondroitin Sulfate
FDA is requesting OMB approval of an experimental study of petitioned health claims on glucosamine and chondroitin sulfate. The study examines various petitioned health claims about the effect of glucosamine and chondroitin sulfate on osteoarthritis. The goal of the study is to determine if certain claims about glucosamine/chondroitin (the “product”) and the reduction of risk of specific outcomes related to osteoarthritis, namely joint degradation and cartilage deterioration, create misperceptions on the part of consumers about the intended use of the product. Results of the study will inform the Center for Food Safety and Applied Nutrition decision making process, particularly as it concerns the approval of the use of these claims. The results may also assist in future decisions toward other claims that bear similar characteristics.
The need for consumer research on various dietary supplement claims arises over a concern that consumer's may misinterpret or misperceive a health claim as a treatment claim when the claim does not clearly refer to a specific disease. Traditional health claims for dietary supplements promote the ability of a product to reduce the risk of a particular disease. However, new claims about products promote the ability of a product to reduce the risk of Start Printed Page 31396a specific health outcome without mention of an associated disease. If the specific health outcome is mentioned without a disease, consumers may misunderstand the claim as one that promotes the product's ability to treat, and not reduce the risk of contracting, a particular health outcome.
The larger question of whether or not a consumer interprets a claim as a drug treatment claim or as a health claim will be answered by comparing the effect of various label claim language on a consumer's perceptions of the effect and potency of a product, and the time in which the product will be effective. This is accomplished by answering a number of smaller research questions about claims concerning glucosamine/chondroitin and their relationship to claims that could be made about food products, as well as their relationship to claims that could be made about an over-the-counter (OTC) or pharmaceutical drug.
The working hypothesis underlying the study design is that consumer's perceive dietary supplements as less potent, less effective, and therefore having a weaker effect on a health condition than drugs. A parallel hypothesis is that consumer's perceive dietary supplements as more potent, more effective, and therefore having a stronger impact on a health condition as food. The study is designed to assess the relative position of a dietary supplement product, “DS”, with respect to a food and a drug along three dimensions characterizing the impact of the DS. These three dimensions include the type of effect the consumer believes the DS will have on a health condition, and the perceived effectiveness of the substance at achieving the claimed effect, and the time in which the consumer believes the effect will occur. The study will also assess how various types of claims on food products, drugs, and dietary supplements change how consumers perceive the relative position of these products with each other. The study will determine if the presence of a petitioned claim on the product label causes consumers to perceive the product as more treatment-like in its effect than when an approved health claim is present.
FDA will conduct an experimental study using subjects recruited from an internet panel of 500,000 households. The internet panel methodology allows controlled presentation of visual materials, experimental manipulation of study materials, and the random assignment of participants to experimental conditions. The experimental manipulation of label conditions and random assignment to conditions allows for statistical estimates of the effects of different approaches to conveying information intended by the health claims. Random assignment ensures that mean differences between conditions can be tested using established techniques such as analysis of variance and multiple regression analysis to yield statistically valid estimates of effect size.
The study design is based on the controlled presentation of realistic product labels that carry health claims for glucosamine/chondroitin, as well as a food product and an OTC drug product. The various health claims that are tested vary in terms of the use of language concerning treatment or risk-reduction effects, and the use of terminology related to a disease or a symptom or risk factor of a disease. In addition, on some labels a disclaimer accompanies the claims. A number of labels will carry claims about the product's effect on a specific disease (osteoarthritis) and will serve as control conditions that assess how consumers view the product when the claims mention only symptoms of the disease.
Panel members are recruited by a variety of means designed to reflect all segments of the population. They are required to have a computer with Internet access. Typical panel members receive three or four invitations per month to participate in research projects. Incentives of small monetary value are given to panel members for their participation periodically.
Each participant in the study will examine one of the label products described earlier. The product may be a food, drug, glucosamine, chondroitin sulfate, or glucosamine/chondroitin combination. The study may also include an additional dietary supplement for comparison with the glucosamine and chondroitin product. The label will have a claim about the products effect on the reduction of risk of either osteoarthritis, joint degradation, or cartilage deterioration. The subject will answer a short set of questions related to each of the label products that they have been shown. These questions will pertain to the consumer's perception of the effect (treat/reduce risk) of the product, the relative effectiveness of the product, and the time in which the effect occurs (hours versus years).
The study includes three conditions, representing important types of label claims and label users that constitute benchmarks for assessing the direction and magnitude of effects due to the presence of symptom-like health conditions: (1) A control that is an approved or traditionally worded health claim, i.e., one that mentions risk reduction of a specific disease; (2) a petitioned health claim that mentions a symptom-like condition, but not the disease; and (3) a petitioned health claim with a disclaimer that states that the product is not intended to cure or treat a disease. The key measures for this study are the perceived effects of the product conveyed by the label condition, the effectiveness of the product, and the expected timeframe within which the product is expected to be effective.
FDA will use the information from this study to guide the decision making process concerning current and future petitions for health claims. The agency acknowledges the lack of empirical data about how consumers understand and respond to statements they see in product labeling. The information gathered in this study can be used by the agency to assess likely consumer responses to various options for qualifying health claims based on varied levels of scientific evidence.
FDA estimates the burden of this collection of information as follows:
|No. of Respondents||Annual Frequency per Response||Total Annual Responses||Hours per Response||Total Hours|
|1 There are no capital costs or operating and maintenance costs associated with this collection of information.|
The approaches and wording options for qualified health claims of central interest to the agency requires a complex experimental design. To ensure adequate power to identify differences, the minimum cell size is 60 Start Printed Page 31397participants. This will be sufficient to identify small to medium effects (i.e., r =.15 to .30) for all main effects and first order interactions with power = (1-beta), well in excess of .80 at the .05 significance level.Start Signature
