MEMORANDUM OPINION

Plaintiff Hill Dermaceuticals, Inc. (“Hill”) has brought this action against the U.S. Food 

and Drug Administration (“FDA”), the U.S. Department of Health and Human Services 

(“HHS”), Kathleen Sebelius, in her official capacity as Secretary of HHS, and Margaret 

Hamburg, M.D., in her official capacity of Commissioner of FDA. Amneal Pharmaceuticals, 

LLC (“Amneal”) has intervened as a defendant. Hill manufactures fluocinolone acetonide 

topical oil products under the brand names Derma-Smoothe/FS (Body Oil and Scalp Oil) and 

Derm-Otic Oil Ear Drops. On October 17, 2011, the FDA approved requests by Identi Pharms, 

Inc. (“Identi”) to market purported generic versions of these fluocinolone acetonide products. 

Hill seeks to enjoin the FDA to withdraw or suspend its approval of the three abbreviated new 

drug applications (“ANDAs”) submitted by Identi on the basis that the approval contravenes the 

sameness requirements, the misbranding restrictions, and the bioequivalence requirements of the 

Food, Drug, and Cosmetic Act and its implementing regulations. 21 U.S.C. §§ 355(j)(2)(A)(v), 

355(j)(2)(A)(iv), 352(a); 21 C.F.R. §§ 314.94(a)(8)(iv), 320.1, 320.22(b). Hill also claims that 
2

FDA’s approval of Identi’s three ANDAs constitutes arbitrary and capricious agency action in 

violation of the Administrative Procedure Act. 5 U.S.C. § 706.

Before the Court is plaintiff’s Motion [3] for a preliminary injunction. Upon 

consideration of plaintiff’s Motion, Federal defendants’ opposition [25], intervenor defendant’s 

opposition [40], plaintiff’s reply [27], Federal defendants’ surreply [42], the arguments made in 

open court on November 29, 2011, the entire record in this case, and the applicable law, the 

Court will DENY plaintiff’s Motion [3] for a preliminary injunction. The Court will explain its 

reasoning in the analysis that follows.

I. BACKGROUND

A. Statutory and Regulatory Framework

1. New Drug Applications and Abbreviated New Drug Applications

Under the Federal Food, Drug, and Cosmetic Act (“FDCA”), 21 U.S.C. § 301 et seq., 

pharmaceutical companies seeking to market “pioneer” or “innovator” drugs must first obtain 

FDA approval by filing a new drug application (“NDA”). 21 U.S.C. § 335(a), (b). The NDA 

must contain extensive scientific data and other information, including investigative reports 

demonstrating the drug’s safety and effectiveness, a statement of the drug’s components, and 

specimens of proposed labeling for the packaging of the drug. 21 U.S.C. § 335(b)(1).

The Drug Price Competition and Patent Term Restoration Act of 1984 (“Hatch-Waxman 

Amendments”), codified at 21 U.S.C. § 355 and 35 U.S.C. §§ 156, 271, and 282, permits the 

submission of abbreviated new drug applications (“ANDAs”) for approval of generic versions of 

drug products with approved NDAs. 21 U.S.C. § 355(j). The Hatch-Waxman Amendments 

were intended to balance encouraging innovation in drug development with accelerating the 

availability of lower cost generic alternatives to innovator drugs. See H.R. Rep. No. 98-857 (Part 
3

I), 98th Cong., 2d Sess. at 14–15 (1984), reprinted in 1984 U.S.C.C.A.N. 2547–48; see also TriBio Labs., Inc. v. United States, 836 F.2d 135, 139 (3d Cir. 1987).

2. ANDA Approval Requirements

To obtain approval, ANDA applicants are not required to submit clinical evidence to 

establish the safety and effectiveness of the generic drug product. Rather, an ANDA references 

an approved drug—the reference listed drug (“RLD”)—and relies on FDA’s previous finding 

that the RLD is safe and effective. Additionally, an ANDA applicant must provide sufficient 

information to show that the generic drug product has the same active ingredient or ingredients, 

dosage form, route of administration, and strength as the RLD. 21 U.S.C. § 355(j)(2)(A)(ii), 

(iii). An ANDA application must also demonstrate that its product is bioequivalent to the RLD 

and has the same labeling as the RLD. 21 U.S.C. §§ 355(j)(2)(A)(iv), (v). The agency must 

approve an ANDA unless it finds, among other things, that the ANDA has not provided 

sufficient evidence of the foregoing. 21 U.S.C. § 355(j)(4).

The FDCA requires that an ANDA contain “information to show that the labeling 

proposed for the new [generic] drug is the same as the labeling approved for the listed drug . . . 

except for changes required because of differences approved under a petition filed under [21 

U.S.C. § 355(j)(2)(C)] or because the new drug and the listed drug are produced or distributed by 

different manufacturers.” 21 U.S.C. § 355(j)(2)(A)(v). Permissible labeling differences include 

“differences in expiration date, formulation, bioavailability, . . . [or] labeling revisions made to 

comply with current FDA labeling guidelines or other guidance.” 21 C.F.R. § 314.94(a)(8)(iv).

The FDCA also requires an ANDA to include information showing that the generic drug 

product is bioequivalent to the pioneer drug product. 21 U.S.C. §§ 355(j)(2)(A)(iv), (j)(4)(F); 21 

C.F.R. §§ 314.127(a)(6)(i), 314.94(a)(7). A drug is considered to be bioequivalent if “the rate 
4

and extent of absorption of the drug do not show a significant difference from the rate and extent 

of absorption of the listed drug.” 21 U.S.C. § 355(j)(8)(B)(i). FDA regulations further define 

bioequivalence as “the absence of a significant difference in the rate and extent to which the 

active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives 

becomes available at the site of drug action when administered at the same molar dose under 

similar conditions in an appropriately designed study.” 21 C.F.R. § 320.1(e). The FDA will 

grant a bioequivalence waiver—that is, the FDA will not require the submission of evidence 

obtained in vivo measuring bioequivalence of the two products—if the generic drug product: (1) 

“is a solution for application to the skin, an oral solution, elixir, syrup, tincture, a solution for 

aerosolization or nebulization, a nasal solution, or similar other solubilized form”; (2) “contains 

an active drug ingredient in the same concentration and dosage form as a drug product that is the 

subject of an approved full new drug application or abbreviated new drug application”; and (3) 

“contains no inactive ingredient or other change in formulation from the drug product . . . that 

may significantly affect absorption of the active drug ingredient.” 21 C.F.R. § 320.22(b)(3)(i)–

(iii).

Furthermore, each ANDA must include “the specifications necessary to ensure the 

identity, strength, quality, and purity of the drug substance . . . including, for example, tests [and] 

analytical procedures.” 21 C.F.R. § 314.50(d)(1); 21 C.F.R. § 314.94(a)(9)(i). An applicant 

must submit copies of analytical procedures and related descriptive information “that are 

necessary for FDA’s laboratories to perform all necessary tests on the samples and to validate the 

applicant’s analytical procedures,” including “a detailed description of the methods of analysis 

[and] supporting data for accuracy, specificity, precision and ruggedness.” 21 C.F.R. § 

314.50(e)(2)(i). FDA’s regulations include provisions to ensure the accuracy, reliability, 
5

suitability, and reproducibility of an applicant’s test methods. See 21 C.F.R. §§ 211.165(e), 

211.194(a)(2).

B. Factual Background

1. Hill’s Fluocinolone Acetonoide Products

FDA first approved Hill’s NDA for Derma-Smoothe (fluocinolone acetonide 0.01% 

topical oil) on February 3, 1988. Hill’s NDA includes Body Oil, Scalp Oil, and Oil Ear Drops, 

even though they are separate products. Derma-Smoothe Body Oil is indicated to topically treat 

atopic dermatitis for adult patients and some pediatric patients with moderate to severe atopic 

dermatitis. Derma-Smoothe Scalp Oil is indicated to treat scalp psoriasis on adult patients. 

DermOtic Oil Ear Drops are indicated to treat chronic eczematous external otitis in adults and 

pediatric patients two years of age and older. These products are intended for local, topical use 

and are not intended to be systemically absorbed. FDA has designated Derma-Smoothe as the 

RLDs for generic fluocinolone acetonide topical oil products.

Hill’s Derma-Smoothe products include peanut oil that has been refined in accordance 

with the United States Pharmacopeia-National Formulary (“USP-NF”) standard. When Hill 

submitted a supplement to its NDA in 1998, FDA requested that Hill improve its testing of the 

Derma-Smoothe product because the then-current USP-NF monograph for peanut oil did not 

include enough information to ensure that the peanut oil would be sufficiently free of peanut 

protein. Hill therefore changed its testing to a non-proprietary, commercially available 

“sandwich” enzyme-linked immunosorbent assay (S-ELISA) method to detect residual peanut 

proteins. FDA subsequently approved Hill’s NDA supplement, including product labeling 

stating that the peanut oil used in the Derma-Smoothe product was routinely tested for peanut 
6

proteins using the S-ELISA test and representing that this test could detect peanut proteins to as 

low as 2.5 parts per million (ppm). 

In 2007, Hill submitted another supplement to its NDA in which it proposed to use an 

amino acid analysis instead of the S-ELISA test, claiming that the amino acid analysis was even 

more sensitive than the S-ELISA test. This change was not mandated by the FDA, but the FDA 

approved Hill’s supplement. As a result, the current product labeling on Derma-Smoothe 

includes the following statement: “The peanut oil used in Derma-Smoothe/FS is tested for peanut 

proteins through amino acid analysis which can detect the quantity of amino acids to below 0.5 

parts per million.” 

In March 2008, FDA decided to review Hill’s amino acid analysis and asked Hill to 

provide method validation packages for Hill’s S-ELISA and amino acid tests, plus support for 

Hill’s assertion that the amino acid test “provides for increased safety for the peanut oil 

component and the drug product.” Upon review of the materials submitted by Hill, FDA 

determined that neither the S-ELISA test nor the amino acid test had been appropriately

validated to reliably quantify residual proteins in peanut oil.

2. Hill’s Citizen Petition

In September 2004, Hill submitted a citizen petition to FDA requesting that FDA 

withhold approval of any ANDA for generic versions of Derma-Smoothe products unless it 

required an ANDA applicant to conduct clinical tests. Hill also requested that FDA require 

ANDA applicants to meet a 0.5 ppm upper limit for peanut protein in the refined peanut oil 

vehicle, to be demonstrated by using a test that is validated and capable of quantifying very low 

levels of peanut protein. See Compl. Ex. G (“Citizen Petition Response”), at 1–2.
7

In its response to Hill’s citizen petition, issued in March 2009, the FDA denied Hill’s 

request that FDA automatically reject any ANDA unless the labeling is identical to the RLD 

concerning the amount of peanut protein in the excipient and the test to identify that amount. See

Citizen Petition Response, at 12. FDA based its decision on portions of the FDCA and FDA 

regulations providing that a labeling difference between the generic drug product and the RLD 

may permissibly reflect a difference in manufacturers. See id. (citing 21 U.S.C. §§

355(j)(2)(A)(v), 355(j)(2)(G); 21 C.F.R. § 314.94(a)(8)(iv)).

FDA also rejected Hill’s request that FDA: (1) require ANDA applicants to demonstrate 

that their formulations do not cause an allergic reaction in peanut-sensitive patients and conduct 

studies on peanut-sensitive patients to establish the safety of their products, (2) set an upper limit 

for the amount of residual peanut protein, and (3) require ANDA applicants to demonstrate that 

their peanut oil meets this specification using a test that is “validated and capable of quantifying 

very low levels of peanut protein.” See id. at 24. FDA stated that it would be sufficient for an 

applicant to establish that its topical product is made from peanut oil that has been fully refined 

in accordance with the updated USP-NF standard, because that standard adequately ensures the 

safety of the peanut oil for the indications in question. See id. at 24–25. FDA cited a number of 

recently published studies supporting its conclusion that the USP-NF refining process—which 

had been updated since the agency had approved Hill’s NDA supplement regarding peanut 

protein in 1999—would reduce peanut protein to an acceptable level for the indications at issue. 

See id. at 27–28. FDA thus concluded that a manufacturer of fluocinolone acetonide topical oil 

must merely ensure that the peanut oil used is fully refined and meets the USP-NF standard, 

declining to require an additional test to quantify protein in refined peanut oil because it would 

not improve the safety of products formulated with this excipient. See id. at 30.
8

FDA also denied Hill’s request that the agency require ANDA applicants to conduct 

clinical safety studies on peanut-sensitive patients to establish the safety of the peanut oil used in 

their products, concluding that the process controls included in the USP-NF specification were a 

more reliable means to ensure the safety of each batch. See id. at 31.

3. Derma-Smoothe Labeling

At the time FDA responded to Hill’s citizen petition, Hill had two supplemental NDAs 

pending before the agency related to the labeling format, the statement regarding the amino acid 

test for peanut protein, and Hill’s effort to validate the amino acid test. Based on its conclusions 

in the Citizen Petition Response, in March 2009 FDA declined to approve one supplement 

because Hill’s amino acid test remained unvalidated. See Fed. Defs.’ Opp. Ex. 6. FDA 

subsequently requested that Hill revise its labeling to remove references to the testing method 

and the amount of peanut protein in the product. In September 2009, FDA determined that the 

second supplement was not approvable because Hill declined to make FDA’s requested changes 

to Hill’s product labeling. See Fed. Defs.’ Opp. Ex. 7.

Instead of making the labeling changes that FDA requested in 2009, Hill has requested—

and FDA has granted—multiple extensions in order to respond to FDA’s September 2009 

response letter, claiming that it needs more time to validate its amino acid test method. See Fed. 

Defs.’ Opp. Ex. 8. Hill’s deadline to respond to the FDA is now September 30, 2012.

4. Identi’s ANDA Applications and Generic Products

On October 17, 2011, FDA approved three ANDAs submitted by Identi, each 

corresponding to one of Hill’s Derma-Smoothe products. Derma-Smoothe is the RLD for each 

of the Identi ANDAs. Identi has given intervenor-defendant Amneal the exclusive license to

manufacture and market the generic products, which were launched in mid-November 2011. 
9

Although the generic product labels include precautions for use by peanut-sensitive individuals, 

they do not include the following statement that appears on the labeling for Hill’s products: “The 

peanut oil used in [product] is tested for peanut proteins through amino acid analysis which can 

detect the quantity of amino acids to below 0.5 parts per million.”

II. LEGAL STANDARD

A preliminary injunction is an extraordinary remedy that may only be awarded upon a 

clear showing that the plaintiff is entitled to such relief. Winter v. NRDC, 555 U.S. 7 (2008). To 

obtain a preliminary injunction, a party must establish that: (1) it is likely to succeed on the 

merits; (2) it is likely to suffer an irreparable harm in the absence of preliminary relief; (3) the 

balance of equities tips in its favor; and (4) an injunction is in the public interest. See, e.g., Mills 

v. District of Columbia, 571 F.3d 1304, 1308 (D.C. Cir. 2009); Cobell v. Norton, 391 F.3d 251, 

258 (D.C. Cir. 2004); Nat’l Treasury Emp. Union v. United States, 927 F.2d 1253, 1254 (D.C. 

Cir. 1991). The D.C. Circuit has read the Supreme Court’s decision in Winter to “suggest if not 

to hold ‘that a likelihood of success is an independent, free-standing requirement for a 

preliminary injunction,’” regardless of whether a “sliding-scale analysis” is used to weigh the 

four factors. Sherley v. Sebelius, 644 F.3d 388, 393 (D.C. Cir. 2011) (quoting Davis v. Pension 

Benefit Guaranty Corp., 571 F.3d 1288, 1296 (D.C. Cir. 2009)).

III. ANALYSIS

A. Likelihood of Success on the Merits

Hill’s assertion that it is likely to succeed on the merits of its claims rests on three bases: 

(1) FDA’s approval of generic forms of Hill’s Derma-Smoothe products violates the FDCA’s 

“same labeling” requirement; (2) FDA’s decision not to require generic manufacturers to 

undertake the same safety testing that it required Hill to perform is arbitrary and capricious; and 
10

(3) FDA’s approval of generic versions of Hill’s products violates the FDCA’s bioequivalence 

requirements.

1. Labeling

Hill first argues that FDA’s approval of the generic versions of the Derma-Smoothe 

products violates the FDCA’s “same labeling” requirement because the generic versions do not 

contain the statement that appears on the Derma-Smoothe product stating that the peanut oil used 

in the product “is tested for peanut proteins through amino acid analysis which can detect the 

quantity of amino acids to below 0.5 parts per million.” 

Although the Hatch-Waxman Amendments require that the labeling for a generic drug be 

“the same” as the labeling approved for the RLD, 21 U.S.C. § 355(j)(2)(A)(v), FDA’s 

regulations authorize differences in labeling if “the [generic] drug product and the reference 

listed drug are produced or distributed by different manufacturers.” 21 C.F.R. § 

314.94(a)(8)(iv). FDA says that its decision to approve the ANDAs without the same labeling as 

Hill’s products falls into this exception, because such “differences between the applicant’s 

proposed labeling and labeling approved for the reference listed drug may include . . . labeling 

revisions made to comply with current FDA labeling guidelines or other guidance.” Id. The 

preamble to the proposed rule 21 C.F.R. § 314.94(a)(8)(iv) demonstrates that the regulation was 

intended to allow differences in RLD and generic labeling in circumstances where “the reference 

listed drug labeling does not reflect current agency labeling standards; for example, the agency 

may require a change in the labeling of a drug to make available important new information 

about the safe use of a drug product, but the reference listed drug’s labeling has not yet been 

updated to reflect this change.” 54 Fed. Reg. 28872, 28884 (proposed July 10, 1989). 
11

In its response to Hill’s citizen petition, FDA determined that adherence to the current 

USP-NF industry standard is sufficient to ensure that residual peanut protein remains at safe 

levels, eliminating the need for ANDA sponsors to conduct batch testing such as Hill had 

conducted. As a result, the FDA declined to require ANDA labeling to reference such a test. 

See Citizen Petition Response, at 27–30. The Court finds that FDA’s response to Hill’s citizen 

petition is “other guidance” establishing new safety standards that should be reflected on the 

product labeling, which properly supports the FDA’s decision to approve ANDAs with different 

labeling than the RLD Derma-Smoothe under the exception spelled out in 21 C.F.R. § 

314.94(a)(8)(iv). The exception provided for by the statutory language plainly supports FDA’s 

approval of the ANDAs at issue, and Hill has failed to demonstrate through other arguments how 

it is likely to succeed on the merits under its theory that FDA’s approval of the generic versions 

of the Derma-Smoothe products somehow violates the FDCA’s “same labeling” requirement 

because it is not subject to this exception.

2. Testing

Hill also claims that FDA’s decision not to require generic manufacturers to undertake 

the same safety testing that it required Hill to perform is arbitrary and capricious. According to 

Hill, FDA has violated the principle of reasoned decision making that an administrative agency 

must treat like cases alike and may not impose arbitrary and unequal regulatory burdens on 

similarly situated parties. See Westar Energy, Inc. v. FERC, 473 F.3d 1239, 1241 (D.C. Cir. 

2007). Specifically, Hill argues that FDA compelled Hill to invest millions of dollars to develop 

and perform its amino acid test, yet has not required generic manufacturers to satisfy the same 

testing requirements. As a result, says Hill, the FDA has improperly approved a generic product 

that has a different risk/benefit profile than the approved drug on which the ANDA is based, 
12

because Hill’s product has a known and tested quantity of residual peanut protein of less than 0.5 

parts per million, while the generic has an unknown quantity of residual peanut protein. Hill 

argues that the generic poses a greater risk to healthcare providers and peanut-sensitive 

individuals because it has not undergone the same testing as the RLD.

However, in its response to Hill’s citizen petition, FDA determined that “at this time, 

there does not appear to be any test that has been validated for the purpose of reliably 

quantifying residual protein in peanut oil,” including Hill’s amino acid analysis that is referenced 

on the Derma-Smoothe labeling. Citizen Petition Response, at 26. Accordingly, the generic 

product and Derma-Smoothe do in fact have the same risk/benefit profile, because neither 

product is tested in a manner that reliably proves the quantity of residual peanut protein 

contained in the product. It would be nonsensical for FDA to require the generic products to 

undergo Hill’s amino acid analysis—a test that FDA has not validated—merely so that the 

generic products would be tested in the same manner as the RLD. FDA therefore did not act in 

an arbitrary and capricious manner when it approved the fluocinolone acetonide ANDAs.

Notably, when FDA responded to Hill’s citizen petition and stated that Hill’s amino acid 

analysis was not validated, Hill had two supplemental NDAs pending before the agency related 

to the labeling format, the statement regarding the amino acid test for peanut protein, and Hill’s 

effort to validate the amino acid test. Based on its conclusions in its Citizen Petition Response, 

in March 2009 FDA declined to approve one supplement because Hill’s amino acid test 

remained unvalidated. See Fed. Defs.’ Opp. Ex. 6. FDA subsequently requested that Hill revise 

its labeling to remove references to the testing method and the amount of peanut protein in the 

product. In September 2009, FDA determined that the second supplement was not approvable 

because Hill declined to make FDA’s requested changes to Hill’s product labeling. See Fed. 
13

Defs.’ Opp. Ex. 7. But instead of making the labeling changes that FDA requested in 2009, Hill 

has requested—and FDA has granted—multiple extensions in order to respond to FDA’s 

September 2009 response letter, claiming that it needs more time to validate its amino acid test 

method. See Fed. Defs.’ Opp. Ex. 8. Hill’s deadline to respond to the FDA is now September 

30, 2012, and the reference to the amino acid analysis remains on the Derma-Smoothe product 

labeling. 

While FDA’s decision to approve the fluocinolone acetonide ANDAs was not arbitrary 

and capricious, its subsequent actions allowing references to an unvalidated test to remain on the 

Derma-Smoothe product labeling may very well have been. This does not weigh in Hill’s favor; 

rather, it demonstrates that Hill continues to misrepresent the efficacy of a testing method on its 

labeling that the FDA has declined to validate. Nonetheless, the fact that FDA may have acted 

improperly by extending its approval of Hill’s current labeling is immaterial here because the 

FDA did not act in an arbitrary and capricious manner by not requiring generic manufacturers to 

undertake unvalidated amino acid testing, and Hill has failed to demonstrate a likelihood of 

success on the merits of its argument otherwise.

3. Bioequivalence

Under its third theory, Hill asserts that the FDA’s approval of the generic products 

violates the statutory bioequivalence requirements. The FDA will grant a bioequivalence waiver

(“biowaiver”) for an ANDA—that is, the FDA will not require the submission of evidence 

obtained in vivo measuring bioequivalence of the two products—if the generic drug product: (1) 

“is a solution for application to the skin, an oral solution, elixir, syrup, tincture, a solution for 

aerosolization or nebulization, a nasal solution, or similar other solubilized form”; (2) “contains 

an active drug ingredient in the same concentration and dosage form as a drug product that is the 
14

subject of an approved full new drug application or abbreviated new drug application”; and (3) 

“contains no inactive ingredient or other change in formulation from the drug product . . . that 

may significantly affect absorption of the active drug ingredient.” 21 C.F.R. § 320.22(b)(3)(i)–

(iii).

All parties agree that the second and third requirements for a biowaiver are satisfied. 

Thus, the question of whether FDA properly granted a biowaiver turns on whether the DermaSmoothe products are solutions. The parties have made conflicting submissions regarding the

definition and makeup of a “solution.” Hill argues that its products are not solutions, and thus 

the requirements for a grant of a biowaiver are not met. FDA counters that the Court should 

defer to the agency’s expertise and uphold its decision to grant a biowaiver to the generic 

products. The Court declines to blindly uphold the FDA’s purported scientific decisions before

reviewing the complete administrative record and examining the bases for FDA’s decision to 

grant the biowaiver. Yet FDA’s failure to provide the Court with the full administrative record 

at this point also means that the Court does not have enough information at this time to 

determine whether Hill is likely to succeed on the merits of its claim that its products are not 

solutions, rendering FDA’s grant of a biowaiver improper. Without the complete administrative 

record before the Court, the plaintiff has not made a showing that it is likely to succeed on the 

merits of its claim under the theory that Derma-Smoothe is not a solution and thus FDA’s grant 

of a biowaiver was improper. 

B. Likelihood of Irreparable Harm

Although Hill has failed to demonstrate a substantial likelihood of success on the merits, 

it makes a strong showing that it is likely to suffer irreparable harm in the absence of a 

preliminary injunction. Irreparable harm exists “where the movant has made a strong showing 
15

that the economic loss would significantly damage its business above and beyond a simple 

diminution in profits.” Mylan Pharms., Inc. v. Shalala, 81 F. Supp. 2d 30, 43 (D.D.C. 2000). 

“To shoehorn potential economic loss into a showing of irreparable harm, a plaintiff must 

establish that the economic harm is so severe as to ‘cause extreme hardship to the business’ or 

threaten its very existence.” Hi-Tech Pharmacal Co. v. FDA, 587 F. Supp. 2d 1, 11 (D.D.C. 

2008) (citing Gulf Oil Corp. v. Dep’t of Energy, 514 F. Supp. 1019, 1025 (D.D.C. 1981)).

Hill argues that, absent injunctive relief, it will suffer significant damage to its business. 

Hill is a small, family-owned company with 150 full-time employees that depends upon its 

Derma-Smoothe products for the company’s livelihood, as the products make up 90% of Hill’s 

revenues and sales. See Compl. Ex. D, ¶¶ 6, 17–21. Historical evidence demonstrates that 

generic drugs have achieved up to 90% market saturation within several months of entering the 

market. See id. ¶ 20. As the Supreme Court recently observed, “[n]inety percent of drugs for 

which a generic version is available are now filled with generics” and “[i]n many cases, once 

generic versions of a drug enter the market, the brand-name manufacturer stops selling the 

brand-name drug altogether.” PLIVA, Inc. v. Mensing, 131 S. Ct. 2567, 2584 (2011). Because 

pharmacists will substitute the generic product for the brand-name drug—and are often required 

to substitute generic products under state law—a generic drug company will automatically 

capture a sizeable portion of the sales of the drug, even if the generic is only marginally less 

costly and not as safe as the branded drug. See Pl.’s Reply Ex. 3, ¶ 9.

This evidence demonstrates that new competition from a generic in the marketplace will 

almost certainly cause Hill severe market loss and economic injury, which, given the primary 

role that the Derma-Smoothe products play in Hill’s business, could be completely devastating to 
16

the company’s vitality. Hill thus makes a strong showing that it is likely suffer irreparable harm 

in the absence of a preliminary injunction. 

C. Balance of Equities and the Public Interest

Amneal has demonstrated that it would suffer substantial harm were the Court to enter a 

preliminary injunction. Amneal has already incurred considerable expenses to launch its generic 

products, including the costs of research and development, regulatory matters, manufacturing, 

labeling, and marketing. Mot. to Intervene Ex. 1, ¶ 5. Additionally, Amneal has secured at least 

ten contracts with customers for the sale of the generic products. Id. A preliminary injunction 

would require Amneal to discontinue the marketing and distribution of its products, which would 

result in lost profits on current sales, wasted investment in product and labels already 

manufactured, and uncertainty about future attempts to market and sell the products. Id. ¶ 6. 

Furthermore, if—as the Court has found—Hill is not likely to establish that the 

fluocinolone acetonide ANDAs were wrongly approved, then public interest considerations 

weigh against a preliminary injunction. See, e.g., Serono Labs., Inc. v. Shalala, 158 F.3d 1313, 

1326 (D.C. Cir. 1998). The purpose of the Hatch-Waxman Amendments is to provide the public 

with the benefits of generic competition to branded drugs. See id. at 1326–27. Congress 

expected that competition “to make available more low cost generic drugs.” H.R. Rep. No. 98-

857, pt. 1, at 14 (1984), reprinted in 1984 U.S.C.C.A.N. 2647, 2647. Even in this case, where

the generic product is only marginally cheaper than Derma-Smoothe and the savings to 

consumers will not be significant, Congress’s purpose in passing the Hatch-Waxman 

Amendments is directly implicated. FDA is mandated by the FDCA to make lower-cost generic 

drugs available to the public where, as here, those drugs are found to meet the requirements for 
17

approval. It is therefore not in the public interest for the Court to grant a preliminary injunction 

preventing these generic drugs from being sold on the market.

Despite Hill’s strong argument that it is likely to suffer harm to its business in the 

absence of a preliminary injunction, the risk that Hill will lose its market share is outweighed by 

the strong public interest in the availability of lower-cost generic drugs in the market. 

Furthermore, Hill has failed to demonstrate that it has suffered any loss at all since Amneal’s 

product launch in mid-November—rather, Hill’s claimed harm will manifest itself at some 

uncertain point in the future. Conversely, were the Court to enter a preliminary injunction, 

Amneal would undoubtedly suffer immediate harm because it would be forced to remove its 

generic products from the market and thus would be unable to perform on its contracts related to 

the generic products. Moreover, entering a preliminary injunction would not preserve the status 

quo, as Amneal’s generic products have already launched. The balance of equities therefore 

weighs in favor of Amneal and the public interest and against Hill.

IV. CONCLUSION

Although Hill has made a strong showing that it will likely suffer irreparable harm in the 

absence of a preliminary injunction, this showing is outweighed by Hill’s inability to 

demonstrate any likelihood of success on the merits of its claims against FDA. Indeed, 

“[w]ithout any probability of prevailing on the merits, [a plaintiff’s] purported injuries, no matter 

how compelling, do not justify preliminary injunctive relief.” Am. Bankers Ass’n v. Nat’l Credit 

Union Admin., 38 F. Supp. 2d 114, 140 (D.D.C. 1999). Additionally, the balance of equities 

weighs in favor of Amneal and the public interest and away from granting a preliminary 

injunction to Hill. For the foregoing reasons, Hill’s Motion for a preliminary injunction is 

hereby DENIED.
