`
`SHANNON WEBB, individually, and on behalf of
`all others similarly situated,
` Plaintiff,
`
`v.
`
`
`PFIZER, INC.,
` Defendant
`
`
`
`
`
`Plaintiff Shannon Webb (“Plaintiff”), by and through their undersigned counsel, brings this
`
`action individually and on behalf of all others similarly situated, to seek economic damages for
`
`those who paid for or made reimbursements for generic varenicline-containing drugs (“VCDs”)
`
`that were illegally and willfully manufactured, distributed, and/or introduced into the market by
`
`Defendant Pfizer, Inc. (“Pfizer”).
`
`INTRODUCTION
`This case arises from adulterated, misbranded, and unapproved varenicline-
`
`1.
`
`containing drugs (“VCDs”) that were designed, manufactured, marketed, distributed, packaged,
`
`and/or ultimately sold by Defendant Pfizer, Inc., in the United States under the brand name
`
`Chantix®. These VCDs are non-merchantable, and are not of the quality represented by Defendant.
`
`2.
`
`The brand name drug Chantix is known generically as varenicline (as the tartrate
`
`salt), and is a partial nicotine agonist. It is a first-line therapy in the treatment to aid in smoking
`
`cessation. Unlike many other smoking cessation aids, Chantix does not contain nicotine.
`
`3.
`
`Pfizer obtained approval from the United States Food and Drug Administration
`
`
`
`

`
`
`
`Case 1:21-cv-08244 Document 1 Filed 10/06/21 Page 2 of 55
`
`
`
`(“FDA”) to sell Chantix as a first of its kind treatment in May 2006.
`
`4.
`
`Chantix quickly became one of Pfizer’s fastest growing products. Major media
`
`spending on Chantix totaled $55 million in 2007 (the year after its approval). In the year Chantix
`
`was launched, Pfizer spent $4.3 million in medical journal advertisements alone.
`
`5.
`
`The market rapidly embraced Chantix, and continues to do so to this day. For
`
`example, from launch through 2015, the number of Chantix prescriptions amongst Medicaid
`
`beneficiaries increased 13,277% (thirteen-thousand, two-hundred seventy-seven percent).1
`
`6.
`
` The price for Chantix has steadily climbed since its launch. Price estimates at
`
`launch were approximately $113.98, which climbed to $254.50 as of 2015. In 2018, the price
`
`nearly doubled to $485 for a 30-day supply, bringing in $997 million in sales that year.2
`
`7.
`
`The market for smoking cessation treatments remains robust and continues to grow.
`
`Pfizer’s Chantix sales remain strong, with sales of at least $919 million last year. Indeed, Chantix
`
`was Pfizer’s eight-best-selling product in 2020. To this day, Chantix remains one of the few, and
`
`most prevalent, smoking cessation drug treatments, and one of Pfizer’s top drug products. Pfizer
`
`extended patent protection on Chantix to ensure exclusivity through at least August 2022, thus
`
`ensuring Pfizer’s Chantix is the exclusive varenicline product without generic competition
`
`currently.
`
`8.
`
`At all pertinent times for this action, Defendant represented and warranted to
`
`consumers that its VCDs were therapeutically equivalent to and otherwise the same as the FDA-
`
`approved brand name drug Chantix. Specifically, Defendant represented and warranted that the

`
`
`VCDs were fit for their ordinary uses, met the specifications of Defendant’s FDA-approved
`
`labeling materials, and were manufactured and distributed in accordance with all applicable laws
`
`and regulations.
`
`9.
`
`However, Defendant willfully ignored warnings about the operating standards, and
`
`knowingly and fraudulently manufactured, sold, labeled, marketed, and/or distributed adulterated
`
`and/or misbranded VCDs for purchase in the United States by consumers.
`
`10.
`
`Defendant VCDs were adulterated and/or misbranded (and thereby rendered
`
`worthless) through contamination with a probable human carcinogen known as n-nitroso-
`
`varenicline. Additionally, Defendant was on notice of other potential nitrosamines as well, such
`
`as n-nitrosdimethylamine (“NDMA”) and n-nitrosodiethlamine (“NDEA”).
`
`11.
`
`According to the FDA and other global health authorities, nitrosamines are
`
`dangerous probable human carcinogens.
`
`12.
`
`According to FDA testing, VCDs subject to this action contained NDMA
`
`contamination levels many times higher than the FDA’s updated interim limits for NDMA and
`
`other nitrosamine impurities.
`
`13.
`
`On July 2, 2021, and July 19, 2021, Pfizer initiated recalls of VCDs “because [the
`
`product] may contain levels of a nitrosamine impurity, called N-nitroso-varenicline, above FDA’s
`
`acceptable intake limit.”3 The FDA has yet to release full testing results for other nitrosamine
`
`impurities. On September 16, 2021, Pfizer extended its recall to all Chantix.4

`
`
`
`VCDs dates back many years, at which point Defendant had actual and/or constructive notice of
`
`the contamination.
`
`15.
`
`Ironically, the Defendant’s wrongful acts resulted in persons who sought to use
`
`smoking products less end up with a Chantix pill that contained a carcinogen.
`
`16.
`
`The Class Plaintiffs paid for VCDs that were illegally and willfully introduced into
`
`the market by Defendants, which caused them and the millions of other VCD consumers, to sustain
`
`economic damages. Defendant’s VCDs were not fit for their ordinary use and Defendant has been
`
`unjustly enriched through the sale of these knowingly adulterated and/or misbranded drugs.
`
`Defendant’s conduct, as detailed in this Complaint, also constitutes actionable common law fraud,
`
`consumer fraud, and other violations of state and federal law.
`
`PARTIES
`
`A. Plaintiff
`Plaintiff Shannon Webb is a citizen and resident of Schenectady, New York.
`17.
`
`During the class period, Plaintiff Webb paid money for one or more of Defendant’s VCDs. The
`
`product purchased bore a unique National Drug Code (“NDC”) which denoted that it was indeed
`
`sold, manufactured, and/or distributed into the United States supply chain by Defendant.
`
`Defendant in this paragraph expressly and impliedly warranted to Plaintiff Webb (either directly
`
`or indirectly by adopting warranties that were passed along to and incorporated by another
`
`Defendant further downstream and as mentioned in this paragraph) that their respective VCDs
`
`were the same as the branded Chantix. But in fact, Plaintiff Webb bought a product that was not
`
`the same as Chantix. Had Plaintiff Webb known the product was not the same, Plaintiff Webb
`
`would not have paid for these Defendant’s VCDs. Likewise, had Defendant’s deception about the
`
`impurities within their products been made known earlier, Plaintiff Webb would not have paid for
`
`Defendant’s VCDs.

`
`
`
`
`B. Defendant
`Defendant Pfizer, Inc. (“Pfizer”) is a Delaware corporation with its principal place
`18.
`
`of business at 235 East 42nd Street, New York, NY 10017. Pfizer on its own and/or through its
`
`subsidiaries regularly conducts business throughout the United States and its territories and
`
`possessions. At all times material to this case, Pfizer has been engaged in the manufacturing, sale,
`
`and distribution of adulterated and/or misbranded generic VCDs in the United States.
`
`FACTUAL ALLEGATIONS
`
`I. Background
`A. Prescription Drug Reimbursement
`The pharmaceutical supply chain in the United States consists of four major actors:
`19.
`
`pharmaceutical manufacturers, wholesale distributors, pharmacies, and Pharmacy Benefit
`
`Managers (“PBMs”).
`
`20.
`
`Pharmaceutical manufacturers produce drugs that they distribute to wholesale
`
`distributors, who further distribute to retail or mail-order pharmacies. Pharmacies dispense the
`
`prescription drugs to beneficiaries for consumption. Prescription drugs are processed through
`
`quality and utilization management screens by PBMs.
`
`21.
`
`Third-party payors (“TPPs”) contract with and pay PBMs to administer their drug
`
`programs. PBMs, acting as agents for the TPPs, are tasked with developing drug formularies (the
`
`list of drugs included in coverage at various pricing “tiers”), processing claims, creating a network
`
`of retail pharmacies, and negotiating with pharmaceutical manufacturers. TPPs pay PBMs to
`
`control prescription drug costs. In some instances, PBMs are responsible for placing generic drugs,
`
`such as VCDs, on the TPPs’ formularies.
`
`22.
`
`In conducting formulary management, TPPs and their PBMs reasonably expect that
`
`generic prescription drugs reimbursable on their formularies are bioequivalent or otherwise the
`
`
`
`
`5
`
`
`
`Case 1:21-cv-08244 Document 1 Filed 10/06/21 Page 6 of 55
`
`
`
`same as their RLD counterparts. TPPs seek to include the lowest cost generic drugs possible in
`
`their formularies. This is only made possible because of the manufacturers’ and distributors’
`
`representations that these generic drugs, such as the Defendant’s VCDs, comply with their
`
`respective ANDAs, which state that the generic drugs are bioequivalent to their respective branded
`
`drug. Thus, the TPPs permitted the VCDs to be included on their formularies based on the
`
`Defendant’s misrepresentations that their VCDs were bioequivalent to Chantix, complied with all
`
`current Good Manufacturing Practices (“cGMPs”), and were safe for consumption.
`
`23.
`
`The formulary placement corresponds with the amount that a plan participant must
`
`contribute as a co-payment when purchasing a drug — the higher the placement, the lower the co-
`
`payment, and the higher likelihood that plan beneficiaries will purchase the drug instead of a more
`
`expensive alternative. As a result, higher formulary placement increases the likelihood that a
`
`doctor will prescribe the drug. TPPs provide copies of their PBMs’ formularies to providers,
`
`pharmacists, and patients in their network to aid prescribers’ adherence to the formulary.
`
`24.

`
`pharmaceutical supply chain:5

`
`
`
`
`25. When a patient presents his/her prescription at a pharmacy, the drug’s placement
`
`on the TPP’s formulary will determine the amount of the patient’s co-payment. Once the patient’s
`
`prescription is filled, the pharmacy submits a claim to the PBM for reimbursement. PBMs then
`
`accumulate those individual reimbursements and present them to TPPs for payment.
`
`
`
`B. Prescription Drug Product Identification and Tracing
`
`26.
`
`For each approved product (whether brand or generic) the FDA issues a unique 10-
`
`digit code (the National Drug Code, or NDC) that follows the product from manufacturing through
`
`retail dispensing. The NDC embeds details about the specific product, including the identity of the
`
`manufacturer (or labeler), the strength, dosage form, and formulation of the drug, and the package
`
`size and type.6
`
`27.
`
`The NDC is a critical component of each and every transfer of a prescription drug
`
`(from the manufacturer to the wholesaler; from the wholesaler to the retailer; and from the retailer
`
`to the consumer) and therefore every transaction is accompanied by and labeled with the NDC.
`
`This same code is used by TPPs in the real-time claims adjudication process to identify the precise
`
`dollar amount they will reimburse the pharmacy for a particular prescription drug purchase.
`
`28.
`
`Retail prescription labels display the NDC of the dispensed product, which is part
`
`of the electronic dispensing record. In many cases, the “lot” number will also appear on the
`
`prescription bottle provided to the consumer and, thus, specifically indicate whether the recall
`
`applies to the particular pills in the bottle.7
`
`29.
`
`The lot number is also used to report issues arising around a particular drug. For
`
`example, lot numbers are used by pharmacists to report Adverse Events (“AE”) (i.e., patient-

`7 A lot number is an identification number tied to a particular lot of pills from a single manufacturer.

`
`
`
`specific side effects or complications associated with the use of a prescription drug). This is an
`
`important part of drug safety monitoring in the United States and has led to recalls or relabeling of
`
`numerous drugs. Pharmacists make such reports using the FDA’s MedWatch system using Form
`
`3500.8
`
`
`
`
`
`C. The Drug Supply Chain Security Act Requires Tracing of Product
`
`30.
`
`The Drug Supply Chain Security Act (“DSCSA”)9 was enacted in 2013, and
`
`requires prescription drug manufacturers, wholesalers, repackagers, and pharmacies to
`
`“[e]xchange information about a drug and who handled it each time it is sold in the U.S. market.”
`
`31.
`
`The DSCSA was implemented as one part of the Drug Quality and Security Act
`
`(“DQSA”), aimed at addressing vulnerabilities in the drug supply chain, and facilitating tracing of
`
`certain prescription drugs in finished dosage form through the supply chain. 10
`
`32. While the DSCSA was enacted in 2013, participants in the pharmaceutical supply
`
`chain (including various Defendant here) maintained similar information as a part of their ordinary
`
`course of business prior to the enactment of the DSCSA.
`
`33.
`
`The DSCSA generally requires participants in the drug supply manufacturing chain
`
`(starting from the manufacturer, through the wholesaler, to the retail pharmacy) to retain, for every
`
`pharmaceutical drug transaction, the following information about that transaction: product name;
`
`National Drug Code; container size; number of containers; lot number; date of transaction; date of
`
`shipment; and name and address of the entity transferring ownership and taking ownership of the

`
`product.
`
`34.
`
`The DSCSA requires that this data be kept in a manner to allow these authorized
`
`participants to respond within 48 hours to requests from appropriate federal or state officials — in
`
`the event of a recall or for the purpose of investigating suspect product or an illegitimate product
`
`— for the transaction history of the pharmaceutical product. 11
`
`35.
`
`The supply chain for distribution of prescription drugs in the U.S. is highly
`
`concentrated. This means that data obtained from a relatively small number of market participants
`
`can provide detailed information about the large majority of VCD sales, transfers and prescription
`
`fills.
`
`36.
`
`The entire process of reimbursing pharmacies and consumers for end-purchases
`
`depends upon the ability to know the precise drug and packaging that was dispensed, as well as
`
`the manufacturer of that drug. This system has necessarily resulted in very high levels of data
`
`standardization in this industry. Although pharmacies maintain their own “pharmacy log” data
`
`reflecting dispensing, sales and return activity, the key elements are fundamentally similar.
`
`37.
`
`Because pharmacies require similar information for their own tracking and
`
`inventory systems, and wholesalers sell to multiple pharmacy chains, the key elements are
`
`fundamentally the same.
`
`38.
`
`Further, all pharmacies must use the basic data fields, definitions and formats
`
`provided in the Telecommunications Guidelines developed by the National Council for
`
`Prescription Drug Programs, the use of which was made mandatory in 2003 under regulations
`
`implementing the Health Insurance Portability and Accountability Act (HIPAA).12 Because of

`
`these HIPAA requirements, all of these inter-related systems (Manufacturers, Wholesalers,
`
`Retailers, and TPPs) use a common language to identify products.
`
`39.
`
`As a general matter, for Medicare and Medicaid compliance, pharmacies typically
`
`keep prescription records for ten years.13
`
`40.
`
`A key part of the DSCSA is the requirement that “product tracing information
`
`should be exchanged” for each transaction and retained for at least six years,14 including the
`
`following transaction information (“TI”):15
`
`• Proprietary or established name or names of the product
`• Strength and dosage form of the product
`• National Drug Code (NDC) number of the product
`• Container size
`• Number of containers
`• Lot number of the product
`• Date of the transaction
`• Date of the shipment, if more than 24 hours after the date of the
`transaction
`• Business name and address of the person from whom and to whom
`ownership is being transferred
`
`For example, the DSCSA also mandates use of a composite “product identifier”

`
`
`
`
`
`D. The Drug Approval Framework
`
`44.
`
`Brand drug companies submitting a New Drug Application (“NDA”) must
`
`
`
`
`
`
`demonstrate clinical safety and efficacy through well-designed clinical trials. 21 U.S.C. § 355 et
`
`seq.
`
`45.
`
`The NDA is the vehicle through which drug sponsors formally propose that the
`
`FDA approve a new drug for sale and marketing in the United States.
`
`46.
`
`An NDA is supposed to provide enough information to permit the FDA to decide
`
`(i) whether the drug is safe and effective for its proposed use(s) and whether the benefits of the
`
`drug outweigh the risks; (ii) whether the drug’s proposed labeling is appropriate and what it should
`
`contain; and (iii) whether the methods used in manufacturing the drug and the controls used to
`
`
`
`
`12
`
`
`
`Case 1:21-cv-08244 Document 1 Filed 10/06/21 Page 13 of 55
`
`
`
`maintain the drug’s quality are adequate to preserve the drug’s identity, strength, quality, and
`
`purity.21
`
`47.
`
`As the FDA puts it, the submitted NDA documentation “is supposed to tell the
`
`drug’s whole story,” including “what the ingredients of the drug are.”22
`
`48.
`
`If a branded drug manufacturer ceases to manufacture a drug that meets all terms
`
`of its NDA approval, or in other words, when the drug is not the same as its corresponding brand-
`
`name drug, then the manufacturer has created an entirely new and unapproved drug.
`
`49.
`
`If a branded drug manufacturer ceases to manufacture a drug that meets all terms
`
`of its NDA approval, or in other words, when the drug is not the same as its corresponding brand-
`
`name drug, the generic manufacturer may no longer rely on the brand-name drug’s labeling.
`
`
`
`E. Approval of the NDA for Chantix
`
`50.
`
`Chantix is known generically as varenicline (as the tartrate salt), and is a partial
`
`nicotine agonist. It is a first-line therapy in the treatment to aid in smoking cessation. At a very
`
`high level,. The drug works by interfering with the nicotine receptors in the human brain. This has
`
`the effect of lessening the pleasure a person gets from smoking, or lessening the craving to smoke.

`
`Chantix’s FDA-approved labeling specifies the active and inactive ingredients.

`
`
`F. Drugs Must Be Manufactured in Compliance with Good Manufacturing Practices
`
`53.
`
`Under federal law, pharmaceutical drugs must be manufactured in accordance with
`
`“current Good Manufacturing Practices” (“cGMPs”) to ensure they meet safety, quality, purity,
`
`identity, and strength standards. See 21 U.S.C. § 351(a)(2)(B).
`
`54.
`
`21 C.F.R. § 210.1(a) states that the cGMPs establish “minimum current good
`
`manufacturing practice for methods to be used in, and the facilities or controls to be used for, the
`
`manufacture, processing, packing, or holding of a drug to assure that such drug meets the
`
`requirements of the act as to safety, and has the identity and strength and meets the quality and
`
`purity characteristics that it purports or is represented to possess.” In other words, entities at all
`
`phases of the design, manufacture, and distribution chain are bound by these requirements.
`
`55.
`
`The FDA’s cGMP regulations are found in 21 C.F.R. Parts 210 and 211. These
`
`detailed regulations set forth minimum standards for: organization and personnel (Subpart B);
`
`buildings and facilities (Subpart C); equipment (Subpart D); control of components and drug
`
`product containers and closures (Subpart E); production and process controls (Subpart F);
`
`packaging and label controls (Subpart G); holding and distribution (Subpart H); laboratory controls
`
`(Subpart I); records and reports (Subpart J); and returned and salvaged drug products (Subpart K).
`
`The FDA has worldwide jurisdiction to enforce these regulations if the facility is making drugs
`
`intended to be distributed in the United States.
`
`56.
`
`Under federal law, cGMPs include “the implementation of oversight and controls
`
`over the manufacture of drugs to ensure quality, including managing the risk of and establishing
`
`the safety of raw materials, materials used in the manufacturing of drugs, and finished drug
`
`products.” 21 U.S.C. § 351(j). Accordingly, it is a cGMP violation for a manufacturer to contract
`
`out prescription drug manufacturing without sufficiently ensuring the continuing quality of the
`
`
`
`
`14
`
`
`
`Case 1:21-cv-08244 Document 1 Filed 10/06/21 Page 15 of 55
`
`
`
`subcontractors’ operations.
`
`57.
`
`FDA regulations require a “quality control unit” to independently test drug product
`
`manufactured by another company on contract:
`
`There shall be a quality control unit that shall have the responsibility
`and authority to approve or reject all components, drug product
`containers, closures, in-process materials, packaging material,
`labeling, and drug products, and the authority to review production
`records to assure that no errors have occurred or, if errors have
`occurred, that they have been fully investigated. The quality control
`unit shall be responsible for approving or rejecting drug products
`manufactured, processed, packed, or held under contract by another
`company. 21 C.F.R. § 211.22(a).
`
`
`
`58.
`
`Indeed, FDA regulations require a drug manufacturer to have “written procedures
`
`for production and process control designed to assure that the drug products have the identity,
`
`strength, quality, and purity they purport or are represented to possess.” 21 C.F.R. § 211.100.
`
`59.
`
`A drug manufacturer’s “[l]aboratory controls shall include the establishment of
`
`scientifically sound and appropriate specifications, standards, sampling plans, and test procedures
`
`designed to assure that components, drug product containers, closures, in-process materials,
`
`labeling, and drug products conform to appropriate standards of identity, strength, quality, and
`
`purity.” 21 C.F.R. § 211.160.
`
`60.
`
`“Laboratory records shall include complete data derived from all tests necessary to
`
`assure compliance with established specifications and standards, including examinations and
`
`assays” and a “statement of the results of tests and how the results compare with established
`
`standards of identity, strength, quality, and purity for the component, drug product container,
`
`closure, in-process material, or drug product tested.” 21 C.F.R. § 211.194.
`
`G. Adulterated or Misbranded Drugs Are Illegal to Sell
`
`61.
`
`Any drug not manufactured in accordance with cGMPs is deemed “adulterated” or
`
`15

`
`
`
`
`
`
`
`Case 1:21-cv-08244 Document 1 Filed 10/06/21 Page 16 of 55
`
`
`
`“misbranded” and may not be distributed or sold in the United States. See 21 U.S.C. §§ 331(a),
`
`351(a)(2)(B). States have enacted laws adopting or mirroring these federal standards.
`
`62.
`
`Among the ways a drug may be adulterated and/or misbranded are:
`
`a.
`
`“if it has been prepared, packed, or held under unsanitary conditions
`
`whereby it may have been contaminated with filth, or whereby it may have
`
`been rendered injurious to health”23 ;
`
`b.
`
`“if … the methods used in, or the facilities or controls used for, its
`
`manufacture, processing, packing, or holding do not conform to or are not
`
`operated or administered in conformity with current good manufacturing
`
`practice to assure that such drug meets the requirements … as to safety and
`
`has
`
`the
`
`identity
`
`and
`
`strength,
`
`and meets
`
`the quality
`
`and
`
`purity characteristics, which it purports or is represented to possess”24;
`
`c.
`
`“If it purports to be or is represented as a drug the name of which is
`
`recognized in an official compendium, and … its quality or purity falls
`
`below, the standard set forth in such compendium”25; and/or
`
`d.
`
`“If … any substance has been (1) mixed or packed therewith so as to reduce
`
`its quality or strength or (2) substituted wholly or in part therefor.”26
`
`63.
`
`A drug is misbranded:
`
`a.
`
`“If its labeling is false or misleading in any particular”27;
`
`
`
`23 21 U.S.C. § 351(a)(2)(A).
`24 21 U.S.C. § 351(a)(2)(B).
`25 21 U.S.C. § 351(b).
`26 21 U.S.C. § 351(d).
`27 21 U.S.C. § 352(a)(1).

`
`
`
`
`b.
`
`“If any word, statement, or other information required … to appear on
`
`the label or labeling is not prominently placed thereon…in such terms as to
`
`render it likely to be read and understood by the ordinary individual under
`
`customary conditions of purchase and use”28;
`
`c.
`
`If the labeling does not contain, among other things, “the proportion of each
`
`active ingredient”29;
`
`d.
`
`“Unless its labeling bears (1) adequate directions for use; and (2) such
`
`adequate warnings … against unsafe dosage or methods or duration of
`
`administration or application, in such manner and form, as are necessary for
`
`the protection of users”30;
`
`e.
`
`“If it purports to be a drug the name of which is recognized in an official
`
`compendium, unless it is packaged and labeled as prescribed therein”31
`
`f.
`
`g.
`
`h.
`
`“if it is an imitation of another drug”32;
`
`“if it is offered for sale under the name of another drug”33;
`
`“If it is dangerous to health when used in the dosage or manner, or with the
`
`frequency or duration prescribed, recommended, or suggested
`
`in
`
`the labeling thereof”34;
`
`i.
`
`If the drug is advertised incorrectly in any manner35; and/or
`
