Extract

If new refrigerators hurt 7% of customers and failed to work for another one-third of them, customers would expect refunds … manufacturers would be strictly liable for the injuries, and there would be implied warranties even if the manufacturer made no guarantees.

What if physicians could use genetic tests to tailor prescriptions to their patients’ individual genotypes? Physicians and pharmaceutical companies can use pharmacogenomics to decrease the number of adverse drug reactions, increase drug efficacy, and lower health care costs. Unfortunately, cross-labeling rules serve as both legal and policy hurdles for these advances, hurdles the FDA has the power to remove. Part I explains pharmacogenomics and why it currently has a narrow application. Part II discusses the FDA's regulatory approach to pharmacogenomics. Part III explains the legal and policy hurdles of cross-labeling and how they impede the more widespread use of pharmacogenomics. Part IV examines ways to clear the legal cross-labeling hurdles while Part V examines ways to clear the policy cross-labeling hurdles. Finally, Part VI discusses some of the many other complex legal and policy issues that lawmakers, regulators, and the industry will need to resolve in order to realize the full potential of pharmacogenomics.

60 “‘Tailor-made medicines are absurd to the point of being ridiculous’ [said William Haseltine, chairman of Human Genome Sciences, a Rockville, Md., pharmaceutical firm] maintaining that no firm, already reeling from the costs of developing new drugs, would seek to develop five complementary drugs to treat a single disease.

Such risks have already been considered in the arduous risk-utility scrutiny of the expert Food and Drug Administration's approval procedures … . [T]he court must require, as a part of the plaintiff's burden of producing evidence, an articulable basis for disregarding the FDA's determination that the drug should be available. For instance … evidence tending to show that FDA approval was based on erroneous data or on an assumption that the incidence of harmful effects would be significantly lower than the actual incidence the plaintiff can objectively demonstrate. Or … evidence tending to show that notwithstanding the utility of the drug, the qualitative and quantitative harmful effects, although known and warned of, are such that reasonable minds could conclude that the FDA manifestly erred in its finding that the societal benefits of access to the drug are not outweighed by the risks.”).

84 Id. at 17-18 (“A biomarker that is measured in an analytical test system with well-established performance characteristic and for which there is a scientific framework or body of evidence that appears to elucidate the physiologic, toxicologic, pharmacologic, or clinical significance of the test results. A probable valid biomarker may not have reached the status of a known valid marker because, for example, of any one of the following reasons: - The data elucidating its significance may have been generated within a single company and may not be available for public scientific scrutiny. – The data elucidating its significance, although highly suggestive, may not be conclusive. – Independent verification of the results may not have occurred.”).

85 Exploratory biomarkers lack the evidence to be considered known valid or probable valid biomarkers. See Food & Drug Admin., supra note 15, at 5 (“Many pharmacogenomic testing programs implemented by pharmaceutical sponsors or by scientific organizations are intended to develop the knowledge base necessary to establish the validity of new genomic biomarkers … test results are not useful in making regulatory judgments pertaining to the safety or effectiveness of a drug and are not considered known or probable valid biomarkers.”); Huang, supra note 6, at 91.

86 During the IND phase, the sponsor must submit data if: (1) “The test results are used for making decisions pertaining to a specific clinical trial or in an animal trial used to support safety (e.g. the results will affect dose and dose schedule selection, entry criteria into a clinical trial safety monitoring, or subject stratification); (2) A sponsor is using the test results to support scientific arguments pertaining to … dosing and dosing schedule, or the safety and effectiveness of the drug”; (3) the data concerns a known valid biomarker. Food & Drug Admin., supra note 15, at 8-9 (interpreting 21 C.F.R. § 312.23(a)(8) (2007) (A sponsor that intends to conduct a clinical investigation must submit with the IND application “adequate information about pharmacologic and toxicological studies of the drug involving laboratory animals or in vitro, on the basis of which the sponsor has concluded that it is reasonably safe to conduct the proposed clinical investigations”), § 312.23 (a) (9) (A sponsor must submit a summary of previous human experience with the drug known to the applicant including information relevant to the evaluation of the safety of the drug), § 312.23(a)(10)(iv) (A sponsor must submit any other information that would aid evaluation of the safety and design of the proposed clinical trial), and § 312.23(a)(11) (a sponsor must submit “any other relevant information needed for review of the application” if requested by FDA)).

During the NDA and BLA phases, sponsors must submit data if: (1) the sponsor intends to use the data in the drug label or to support scientific arguments made by the sponsor about drug dosing, safety, patient selection or monitoring, or if pharmacogenomic tests are essential to achieving the dosing, safety, or effectiveness described in the labeling, (2) the data concerns a known valid biomarker, or (3) the data concerns a probable valid biomarker. The guidance also recommends submission of a synopsis of exploratory data. Id. at 10, 11 (interpreting 21 C.F.R. § 314.50 (2007)) (“[T]he NDA application is required to contain reports of all investigations of the drug product sponsored by the applicant, and all other information about the drug pertinent to an evaluation of the application that is received or otherwise obtained by the applicant from any source.”), and 21 C.F.R. § 601.2 (2007) (BLA manufacturers must “submit data derived from nonclinical laboratory and clinical studies that demonstrate that the manufactured product meets prescribed requirements of safety, purity, and potency”).

After an NDA or BLA is approved, a sponsor must submit data concerning known or probable valid biomarkers in the annual report as synopses or abbreviated reports. Id. at 11 (interpreting Applications for FDA Approval to Market a New Drug, 21 C.F.R. § 314.81(b)(2) (2007) (The sponsor must annually submit a report containing a “brief summary of significant new information from the previous year that might affect the safety, effectiveness, or labeling of the drug product.”); Changes to an Approved Application, 21 C.F.R. § 601.12 (2007) (A BLA manufacturer “must inform the [FDA] … about each change in the product, production process, quality controls, equipment, facilities, responsible personnel, or labeling established in the approved license application(s).”)).

127 CPC, supra note 105, at 8; CPC, supra note 111, at 4. The CPC believes that FDA should avoid even asking companies to cooperate. See CPC, supra note 105, at 8. “FDA should not apply any pressure on a company to work with another. We have asked a number of companies what they would consider to be pressure, and it appears that companies have a low threshold for feeling pressure by the regulatory agency that governs so much of what they do. We believe that FDA should ask for cooperation from reluctant parties very lightly and frankly in rare circumstances where there is no risk of pressure.” CPC, supra note 105, at 6.

128 “What does it mean that ‘labeling of the approved product would not need to be changed?’ [in 21 C.F.R. § 3.2(e)(3)] This is the critical question because this language determines whether Product B can be approved without the cooperation of Company A. Can we develop criteria that will allow the agency to find that in some cases, the labeling will not need to be changed?” Nancy Stade, Assoc. Chief Counsel, Devices, FDA, Legal Considerations in Cross Labeling Policy, PowerPoint Presentation Before the FDA/DIA, Combination Products and Mutually Conforming Labeling Workshop, 25 (May 10, 2005) (presentation available at http://www.fda.gov/oc/combination/presentations/dia/dia05_10.html).

129 Transcript, supra note 96 (the first half of the workshop was devoted to a discussion of these public health issues).

130 If the other drug is off patent and thus made by many manufacturers, there is no combination product issue because 21 C.F.R. § 3.2(e)(3) is not triggered since B's device would not “specifically identify” the drug. There is also no combination product issue if the genetic test shows a contraindication for an entire class of drugs, such as sulfites.

Combination product includes:

  • (1) A product comprised of two or more regulated components, i.e., drug/device, biologic/device, drug/biologic, or drug/device/biologic, that are physically, chemically, or otherwise combined or mixed and produced as a single entity;

  • (2) Two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and drug products;

  • (3) A drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually specified drug, device, or biological product where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose; or

  • (4) Any investigational drug, device, or biological product packaged separately that according to its proposed labeling is for use only with another individually specified investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

165 Assignment of Agency Component for Review of Premarket Applications, 56 Fed. Reg. 58,754, 58,755 (Nov. 21, 1991) (codified at 21 C.F.R. pt. 3); see also Transcript, supra note 96 (“I was on the writing group for Part 3 and I was also one of the coordinators of getting the CDER-CDRH Agreements in place… . In the preamble, we noted that most of the drugdevice matters would be concomitant use and those did not fall within the area of combination products. So the goal … was to keep the number of products that were … combination products with respect to labeling limited in number and only where it needed to be in place because we, as a writing group [were trying to allow for new technology] … . There is no one left alive that was involved.”) (quoting Leighton Hansel) (emphasis added).

166 See infra note 168.

167 21 C.F.R. § 3.3 (2007) (emphasis added).

168 The rule presents an apparent contradiction. FDA provided that only a narrow class of products should come under the regulations as combination products; but at the same time, it provided that the regulations cover a much broader class that includes products that are not combination products. This can be reconciled by recognizing that the overall purpose of Part 3 is to maximize efficiency. Section 3.1 states that the purpose of including non-combination products under the regulations is to “enhance the efficiency of agency management and operations by providing procedures for determining which agency component will have primary jurisdiction.” Id. § 3.1. FDA wanted to be able to invoke the procedures in Part 3 whenever they are useful in expediting the review process but did not want the procedures to be triggered in cases where they were not useful because primary jurisdiction was not an issue. This would only create additional confusion and would slow down the review process. Thus, FDA expanded the scope of the regulations generally, while providing narrow definitions for combination products.

169 Telephone Interview with Nancy Stade, Office of the Chief Counsel, FDA, in Rockville, Md. (Apr. 3, 2007).

170 But see 21 C.F.R. § 3.2(k) (2007) (“Because combination products are comprised of more than one type of regulated article (biological product, device, or drug), and each constituent part contributes a biological product, device, or drug mode of action, combination products will typically have more than one identifiable mode of action.”). However, this language relates only to determining primary mode of action, an issue that arises even when FDA is only reviewing the device application. See id. Thus, the device alone triggers combination products status, and when FDA reviews the device application, both the device and the drug are considered as components of the combination for the purpose of determining the device's primary mode of action.

171 21 C.F.R. § 3.2(e)(1) is not met because the drug and device are not combined. Sections 3.2(e)(1) and (2) are not met because the drug and device are packaged separately. Section 3.2(e)(4) is not met because the drug is not investigational. Nor is it likely that primary jurisdiction would be “unclear or in dispute” under 21 C.F.R. § 3.3(b), since the drug was already approved and regulated as a drug.

172 See discussion supra Part III (explaining FDA hypothetical).

173 See Intercenter Agreement, supra note 104, at VII.A.1(a)ii.

174 “These intercenter agreements, and any amendments thereto, are nonbinding determinations designed to provide useful guidance to the public.” 21 C.F.R. § 3.5(a)(2)(2007). “The availability of any amendments to these intercenter agreements will be announced by Federal Register notice.” Id. § 3.5(a)(1); see also 21 U.S.C. § 353(g)(4)(F) (2000) (“In [reviewing the intercenter agreements] the Secretary shall consult with stakeholders and … shall determine whether to continue in effect, modify, revise, or eliminate such agreement … and shall publish in the Federal Register a notice of the availability of such modified or revised agreement … .”); H.R. Rep. No. 107-728 at 40 (2002) (“It is the committee's intent that the Office shall not be bound by any existing agreement, guidance or agency practice in determining whether to continue, modify, revise, or eliminate any such agreement … .”).

175 This answers Legal Issue 6 that FDA presented with its hypothetical involving company A and B: “Do the legal issues that arise in the absence of mutually conforming labeling exist independently of § 3.2(e)(3), or can some of these issues be addressed by revisions or clarifications to this part of the definition of a combination product?” Meeting Notice, 70 Fed. Reg. 15,633 –15,634 (Mar. 28, 2005), available at http://www.fda.gov/ohrms/dockets/98fr/05-5978.pdf.

176 See discussion supra Part III (explaining FDA hypothetical).

177 This section of the article discusses regulations that might require the manufacturer of the already approved drug to relabel; but note also that FDA can require the device applicant to label the device in whatever way is necessary to ensure safety and efficacy. 21 U.S.C. § 331(a) (2000) (prohibiting the introduction into interstate commerce of any misbranded device); Id. § 352(f) (stating that a device is misbranded unless its labeling bears adequate directions for use and adequate warnings against uses that might be dangerous to health); Id. § 360c(a)(2) (“the safety and effectiveness of a device are to be determined--(A) with respect to the persons for whose use the device is represented or intended, (B) with respect to the conditions of use prescribed, recommended, or suggested in the labeling of the device, and (C) weighing any probable benefit to health from the use of the device against any probable risk of injury or illness from such use … .”); 21 C.F.R. §§ 801.4, 801.5 (2007) (defining “intended use” and “adequate directions for intended use” for devices respectively); 21 C.F.R. §§ 814.45 (a)(2), 814.45(c) (2007) (FDA may deny a premarket application if the proposed labeling does not comply with Parts 801 or 809 or if the application does not satisfy the safety and effectiveness criteria of § 860.7); 21 C.F.R. § 860.7(d)(1) (2007) (“There is reasonable assurance that a device is safe when … the probable benefits to health from use of the device for its intended uses and conditions of use, when accompanied by adequate directions and warnings against unsafe use, outweigh any probable risks.”).

178 The use of “e.g.” here indicates that the authors of § 3.2(e)(3) saw this as one example of when A might need to relabel, implying that there might be other reasons as well.

180 21 U.S.C. § 331(b).

181 “A drug or device shall be deemed to be misbranded -- (f) … Unless its labeling bears (1) adequate directions for use; and (2) such adequate warnings against use in those pathological conditions or by children where its use may be dangerous to health, or against unsafe dosage or methods or duration of administration or application, in such manner and form, as are necessary for the protection of users, except that where any requirement of clause (1) of this paragraph, as applied to any drug or device, is not necessary for the protection of the public health, the Secretary shall promulgate regulations exempting such drug or device from such requirement.” Id. § 352. Labeling means “all labels and other written, printed, or graphic matters (1) upon any article or any of its containers or wrappers, or (2) accompanying such article.” 21 U.S.C. § 321(m)(2000). In Kordel, the Court held that the phrase “accompanying such article” is broad enough to include more than just writings on or in the article or package containing the article. Kordel v. United States, 335 U.S. 345, 349 (1948). However, the court emphasized the fact that the literature at issue in the case came from the drug maker. Id. at 348 (“In this case the drugs and the literature had a common origin and a common destination.”).

Such intent also may be derived or inferred from labeling, promotional material, advertising, and ‘any other relevant source.’” However, “[t]he vendors’ intent in selling the product to the public is the key element in this statutory definition.”) (citations omitted). “No court has ever found that a product is ‘intended for use’ or ‘intended to affect’ within the meaning of the [Act] absent manufacturer claims as to that product's use.” Brown & Williamson Tobacco v.

The frequency of all clinically significant adverse reactions and the approximate mortality and morbidity rates for patients experiencing the reaction, if known and necessary for the safe and effective use of the drug, must be expressed as provided under paragraph (c)(7) of this section. In accordance with section 314.70 and 601.12 of this chapter, the labeling must be revised to include a warning about a clinically significant hazard as soon as there is reasonable evidence of a causal association with a drug; a causal relationship need not have been definitely established.”).

Section 271(e)(1) makes no distinctions based upon the different FDA classes of medical devices or drugs.”); see also Classen Immunotherapies, Inc. v. Biogen Idec, 381 F. Supp. 2d 452, 455-456 (D. Md. 2005) (holding that § 271(e)(1) exempted Defendant's use of Plaintiff's patented method for evaluating vaccine schedules when Defendant conducted post-approval research studies of vaccines to comply with FDA regulations); Wesley Jessen Corp. v. Bausch & Lomb, Inc., 235 F. Supp. 2d 370, 374-376 (D. Del. 2002) (holding that § 271(e)(1) exempted Defendant's use of Plaintiff's patented contact lens materials in Defendant's post approval study of its contact lenses).

229 “‘It is … well settled that each element of a claim is material and essential, and that in order for a court to find infringement, the plaintiff must show the presence of every element or its substantial equivalent in the accused device.’ […] There can be no infringement as a matter of law if a claim limitation is totally missing from the accused device.” London v. Carson Pirie Scott & Co., 946 F.2d 1534, 1538-1539 (Fed. Cir. 1991) (quoting Lemelson v. United States, 752 F.2d 1538, 1551 (Fed. Cir. 1985)).

230 A party is only liable for contributory infringement for selling an article if the purchaser directly infringes the patent. Husky Injection Molding Sys. Ltd. v. R&D Tool & Eng’g Co., 291 F.3d 780, 784 (Fed. Cir. 2002). A physician and a patient that use B's test are well within their rights if they use the test to modify a dosage or forgo using the drug. Absent a contractual limitation, the purchaser of a patented article may modify that article and replace non-patented parts without infringing the patent. “A purchaser is within its rights to modify a machine by substituting a readily replaceable part … .” Id. at 788 (holding that Defendant did not contributorily infringe by selling molds and carrier plates for Plaintiff's injection molding system because Plaintiff's customers did not directly infringe when they installed these parts); Jazz Photo Corp. v. Int’l Trade Comm’n, 264 F.3d 1094, 1102 (Fed. Cir. 2001) (“The purchaser of a patented article has the rights of any owner of personal property, including the right to use it, repair it, modify it, discard it, or resell it, subject only to overriding conditions of the sale.”). A purchaser of a patented article only impermissibly reconstructs the article if he entirely “spends” the original article and then completes a “second creation” of the article. Dana Corp. v. Am. Precision Co., 827 F.2d 755, 758 (Fed. Cir. 1987) (quoting Aro Mfg. Co. v. Convertible Top Replacement Co., 365 U.S. 336, 346 (1961)).

A physician and patient that use B's test would not impermissibly reconstruct the drug because they would not “spend” and then recreate it. They would not replace any parts of the drug and arguably would not even modify the drug by using the test to adjust dosage; although they would be within their rights to do so. The test is merely a separate diagnostic tool. See Beal Corp. Liquidating Trust v. Valleylab Inc., 927 F.Supp.1350, 1362 (Fed. Cir. 1996) (finding that Plaintiff did not contributorily infringe by selling electrosurgical handpiece unit for use with Defendant's patented electrosurgical base unit because the electrosurgeons did not infringe Defendant's patent by using the handpiece). In many cases, the physician would administer the test before even prescribing the drug and thus arguably would not even “use” the patented drug with the test under the Patent Act. See 35 U.S.C. § 271(a) (prohibiting unauthorized “uses” of a patented invention).
