`INTRODUCTION
`
`
`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`Petitioner Coalition for Affordable Drugs VIII, LLC (“CFAD”) has not
`
`shown a reasonable likelihood of demonstrating that at least one claim of U.S.
`
`Patent 7,932,268 (“the ’268 Patent”) is unpatentable, and its petition should
`
`therefore be denied.
`
`The ’268 Patent claims a method of treating high levels of fats
`
`(hyperlipidemia) and cholesterol (hypercholesterolemia) in the blood through the
`
`step-wise administration of increasing doses of lomitapide, an inhibitor of
`
`“microsomal triglyceride transfer protein” (“MTP”). This invention helped to
`
`solve a problem regarding the safety and tolerability of lomitapide that had stymied
`
`others in the pharmaceutical industry.
`
`Starting in the late 1990’s, Bristol-Myers Squibb (“BMS”) was developing
`
`compounds in the MTP inhibitor class, including BMS-201038 (lomitapide), for
`
`treating hyperlipidemia and hypercholesterolemia. Ex. 1001 at 5:47-49. BMS
`
`discontinued development of lomitapide when clinical trials with fixed doses of the
`
`drug revealed liver and gastrointestinal adverse effects that limited the drug’s
`
`usefulness for treating patients with hyperlipidemia. Ex. 1001 at 6:20-25; Ex. 2002
`
`at 34. It subsequently donated rights to the drug to the University of Pennsylvania.

`Ex. 2001 at 1.

`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`Dr. Daniel Rader, a professor at the Perelman School of Medicine at the
`
`University of Pennsylvania, and the inventor of the ’268 Patent, began pursuing
`
`clinical development of lomitapide using a different approach. Whereas BMS had
`
`attempted to develop a fixed dose of the drug, Dr. Rader sought to reduce the side
`
`effects that had led to BMS discontinuing development of lomitapide by starting
`
`with a low dose of the drug and using a step-wise administration of increasing
`
`doses. Dr. Rader discovered that in many patients this administration regimen
`
`surprisingly reduced the incidence and intensity of side effects that had impacted
`
`the tolerability of the drug, while still allowing effective treatment of patients’
`
`hyperlipidemia. Ex. 1010 at 2-3, ¶¶ 9-14; Ex. 1001 at 13:30-62.
`
`The ’268 Patent claims embody Dr. Rader’s discovery that hyperlipidemia
`
`and hypercholesterolemia can be treated through administration of lomitapide in
`
`increasing step-wise dosages, wherein each dose level is administered for a number
`
`of weeks. See e.g., Ex. 1001, claim 1. Dr. Rader’s discovery is particularly
`
`significant to patients who suffer from homozygous familial hypercholesterolemia
`
`(“HoFH”), a condition characterized by extremely high cholesterol levels, which
`
`was generally not effectively treated with the therapeutic agents that were known
`
`in the art.

`

`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`CFAD’s Petition, which attempts to undermine Dr. Rader’s invention, is
`
`deficient in a number of different ways. First, CFAD has failed to identify all of
`
`the real parties in interest to this proceeding, as required by 35 U.S.C. § 312. 35
`
`U.S.C. § 312(a)(2). CFAD’s other IPR petitions identify real parties in interest that
`
`have not been identified here.
`
`Second, CFAD relies on three purported prior art references, but fails to
`
`meet its burden to prove that two of them—Stein 2004 and the Pink Sheet 2004—
`
`are prior art under 35 U.S.C. §§ 102(a) or 102(b). CFAD does not present proof
`
`that these references were publicly available prior to the priority date.
`
`Third, CFAD’s references relate to a different drug, implitapide, and to a
`
`study which sought to establish a fixed dose of that drug. None of the prior art
`
`relied on by CFAD teaches or suggests a step-wise escalating dose treatment
`
`regimen with lomitapide.
`
`Because CFAD has failed to meet its burden of proving that a person of skill
`
`would have been motivated by the prior art to develop the step-wise, escalating
`
`dose regimen claimed in the ’268 Patent, and that they would have had a
`
`reasonable expectation of success in doing so, the Board should deny CFAD’s
`
`petition.

`
`
`
`II. BACKGROUND FACTS
`A. Hypercholesterolemia and Hyperlipidemia
`Hypercholesterolemia, a condition characterized by very high levels of
`
`cholesterol in the blood, is a well-known risk factor for atherosclerotic
`
`cardiovascular disease (“ASCVD”), the major cause of mortality in the Western
`
`world. Ex. 1001 at 1:23-24. Patients with ASCVD experience a build-up of
`
`plaque inside their arteries, making it difficult for the arteries to carry oxygen-rich
`
`blood to the heart, brain, and other parts of the body. It is well understood that
`
`lowering total cholesterol (“TC”) and low-density lipoprotein (“LDL”) cholesterol
`
`(“LDL-C”) is associated with a significant reduction in clinical cardiovascular
`
`events. Ex. 1001 at 1:25-29.
`
`Hypercholesterolemia is a form of hyperlipidemia, a condition in which
`
`elevated levels of lipids are detected in blood. Triglycerides are one type of fat
`
`(lipid) found in the blood. Although triglycerides store unused calories and
`
`provide the body with energy, higher-than-normal triglyceride levels are often
`
`associated with known risk factors for heart disease. Ex. 1001 at 1:48-51.
`
`Elevated triglyceride levels may also contribute to thickening of artery walls, a
`
`physical change that is believed to be a predictor of atherosclerosis. Id. at 1:51-53.

`

`Patent Owner Preliminary Response
`
`
`
`Treatment of Hypercholesterolemia and Hyperlipidemia
`
`B.
`At the time of the invention, a number of drug treatments were available for
`
`lowering serum cholesterol and triglycerides. The most well-known class of
`
`agents was (and perhaps still is) statins. Ex. 1001 at 2:22-24; 30-31. Other well-
`
`known treatments included niacin and fibric acid derivatives (“fibrates”). Id. at
`
`2:49-51; 58-62.
`
`However, prior to the invention of the ’268 Patent, treatment in patients with
`
`a severe form of familial hypercholesterolemia known as homozygous familial
`
`hypercholesterolemia (“HoFH”) was challenging because LDL levels remained
`
`extremely elevated despite aggressive use of known combination therapy. Ex.
`
`1001 at 1:32-37; 4:24-29. HoFH is a rare genetic condition in which the LDL
`
`receptors are minimally (if at all) functional. Ex. 2002 at 11-12. Conventional
`
`lipid-lowering therapies such as statins were generally not effective in HoFH
`
`patients, because statins require a functioning LDL receptor to work. Id. at 13, 29.
`
`Patients with HoFH develop early and severe ASCVD due to elevated LDL-C
`
`levels, which may lead to early cardiac-related death. Id. at 12. Effective medical
`
`therapy was therefore urgently needed for this group of high-risk patients.
`
`Accordingly, although a number of treatments were available to the general
`
`population for lowering serum cholesterol and triglycerides, “each [had] its own
`
`
`
`
`5
`
`

`

`
`
`
`
`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`drawbacks and limitations in terms of efficacy, side-effects and qualifying patient
`
`population.” Ex. 1001 at 2:3-6. And in terms of the high-risk HoFH patients, there
`
`was an extremely limited range of treatment options that were considered both safe
`
`and efficacious. Id. at 3:55-57. Accordingly, there was a need in this field for
`
`therapeutics which did not suffer from the limitations of the then-existing drug
`
`treatments for hypercholesterolemia and hyperlipidemia.
`
`C. The Development of Lomitapide
`In June 1996, BMS submitted an Investigational New Drug Application
`
`(“IND”) for BMS-201038 (lomitapide), which is an MTP inhibitor. Ex. 2002 at
`
`34. MTP is a protein responsible for shuttling lipid molecules between
`
`membranes, as well as assembling lipoproteins that contain apolipoprotein B
`
`(“apo-B”). It is thought that MTP mediates triglyceride absorption from the
`
`intestine and lipoprotein secretions from the liver by linking lipids to apo-B.
`
`Accordingly, inhibition of MTP typically leads to decreases in circulating levels of
`
`apo-B-containing lipoproteins, including LDL-C. Ex. 2002 at 14.
`
`BMS Abandons Lomitapide
`
`1.
` The BMS development program included clinical studies designed to
`
`assess the safety, pharmacokinetics, and pharmacodynamics of lomitapide as a
`
`monotherapy at fixed doses in subjects with hypercholesterolemia. Ex. 2002 at 34.

`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`Although substantial dose-related decreases in serum lipid parameters were
`
`observed, the clinical trials revealed severe, dose-limiting adverse events. These
`
`adverse events, occurring at fixed doses ranging from 25 mg/day to 100 mg/day,
`
`included gastrointestinal events (e.g., diarrhea) and aminotransferase elevations (an
`
`indicator of liver damage, most likely related to the known MTP side effect of
`
`increased hepatic fat) that led to a high rate of treatment discontinuations. Ex.
`
`1001 at 6:20-25; Ex. 2001 at 30, ¶ B. Ultimately, BMS abandoned the
`
`development of lomitapide in 2000 due to the drug’s side effects. Ex. 2002 at 34.

`dosages used” in the BMS development program, and noting that lomitapide
`
`“could not be developed as a pharmaceutical product of general or wide utility[,]”
`
`in 2003 BMS transferred the IND for BMS-201038 to the University of
`
`Pennsylvania. Exhibit 2001 at 30, ¶ B. Prior to this time, Dr. Daniel Rader, a
`
`professor at the Perelman School of Medicine at the University of Pennsylvania,
`
`began advancing the idea of the clinical development of lomitapide as a treatment
`
`for HoFH, and requested the transfer of the IND from BMS.
`
`At least as early as June 2003, Dr. Rader and his colleague, Dr. Marina
`
`Cuchel, initiated a Phase II study designed to evaluate the efficacy and safety of
`
`
`

`
`
`
`lomitapide in the treatment of subjects with HoFH (Clinical Trial Identifier
`
`NCT01556906 (“the Rader Study”)). See Ex. 2002 at 34-35; Ex. 2003 at 2-3. This
`
`was the first study to evaluate the administration of an MTP inhibitor using a dose-
`
`titration strategy of step-wise, increasing dose levels in an attempt to improve
`
`tolerability and render the drug useful for treating patients. Dr. Rader and his team
`
`employed a dosing regimen of administering lomitapide at a low dose (0.03 mg/kg)
`
`and progressively escalating to higher doses every 4 weeks (0.1 mg/kg, 0.3 mg/kg,
`
`and 1.0 mg/kg, respectively). Ex. 2002 at 35; see also Ex. 2004 at 3-4.
`
`The Rader Study showed a substantially improved tolerability profile and
`
`significant lipid-lowering effects when lomitapide was administered using this
`
`dose-titration strategy. Ex. 2004 at 8 (“. . . [W]e devised a dose-titration strategy
`
`that might allow the intestine to accommodate the increasing inhibition of [MTP].
`
`Under these conditions, all six patients tolerated the drug up to the highest dose . . .
`
`with relatively minor gastrointestinal side effects.”); id. at 7-8 (“Plasma levels of
`
`all other apolipoprotein B-containing lipoproteins were similarly reduced by
`
`inhibition of the microsomal triglyceride transfer protein”). The study concluded
`
`prior to February 4, 2004. Ex. 2005 at 8.

`U.S. Provisional Application No. 60/550,915
`
`3.
`On March 5, 2004, after the Rader Study was completed, Dr. Rader filed
`
`U.S. Provisional Patent Appl. No. 60/550,915 with the United States Patent and
`
`Trademark Office. This application, entitled “Methods For Treating
`
`Hyperlipidemia And Hypercholesterolemia While Minimizing Side-Effects,”
`
`disclosed and claimed a method of treating hyperlipidemia and
`
`hypercholesterolemia by administering an effective amount of an MTP inhibitor
`
`such as lomitapide in a series of escalating doses. See, e.g., Ex. 1006 at 31.
`
`Subsequently, on March 7, 2005, Dr. Rader filed PCT/US2005/007435. A
`
`national stage entry application, U.S. Appl. No. 10/591,923 (“the ’923
`
`Application”), was filed on September 5, 2006. The ’923 Application issued as the
`
`’268 Patent on April 26, 2011. On March 11, 2011, while the ’923 Application
`
`was pending, Dr. Rader filed U.S. Pat. Appl. No. 13/046,118 (“the ’118
`
`Application”) as a continuation application. The ’118 Application, which
`
`eventually issued as U.S. Pat. No. 8,618,135, is also being challenged by the
`
`Petitioner in a parallel proceeding (IPR2015-01835).

`
`
`references that did not suggest how to overcome the difficulty inherent in
`
`effectively dosing MTP inhibitors while minimizing side effects. Ex. 1009 at 6-7
`
`(noting that the cited prior art failed to recognize that constant, high doses of MTP
`
`inhibitor would cause GI-related disorders and increase hepatic fat). The
`
`Applicant established that the cited prior art did not teach either a specific dosing
`
`regimen with a step-wise increase in doses as set forth in the claims, or that a step-
`
`wise dosing of an MTP inhibitor such as lomitapide would reduce adverse effects
`
`while maintaining efficacy compared to a corresponding constant dosing level. Id.
`
`at 7-8.
`
`During prosecution the Applicant submitted the declaration of Dr. William
`
`Sasiela, Ph.D. (“the Sasiela Declaration”), who was then Executive Vice President
`
`and Chief Medical Officer of licensee Aegerion Pharmaceuticals, Inc.
`
`(“Aegerion”). Dr. Sasiela explained the severity of side effects associated with
`
`lomitapide and the fact that BMS had discontinued its study of the compound. Ex.
`
`1010 at 1, ¶¶ 5, 7. The Sasiela Declaration reviewed data from the lomitapide
`
`clinical trials, and described the dramatic decrease in adverse effects in patients
`
`who received a treatment regimen of step-wise, increasing dose levels versus
`
`patients who received a fixed dose of lomitapide. Ex. 1010 at 3, ¶ 14.

`Juxtapid®
`In 2006, Aegerion and the Trustees of the University of Pennsylvania
`
`entered into a license agreement for lomitapide under which Aegerion obtained
`
`exclusive worldwide rights to lomitapide for the treatment of HoFH and certain
`
`other therapeutic areas. Based on the favorable results of the Rader Study,
`
`additional clinical studies were carried out,1 culminating in Aegerion’s submission
`
`of a New Drug Application for Juxtapid® (lomitapide) to the FDA. The FDA
`
`approved Juxtapid® in December 2012, as an adjunct to a low-fat diet and other
`
`lipid-lowering therapies for the treatment of adult patients with HoFH. Ex. 2006.
`
`III. THE BOARD SHOULD DENY CFAD’S PETITION AS
`STATUTORILY DEFICIENT FOR FAILURE TO IDENTIFY ALL
`REAL PARTIES IN INTEREST
`
`An IPR petition “may be considered only if . . . the petition identifies all real
`
`parties in interest.” 35 U.S.C. § 312(a)(2). This statutory requirement is a
`
`“threshold issue.” ZOLL Lifecor Corp. v. Philips Elec. N. Am. Corp., Case
`
`IPR2013-00606, Paper 13 at 8 (P.T.A.B. Mar. 20, 2014). A real party in interest is
`
`a party that “desires review” of the patent, and “may be the petitioner itself, and/or
`
`
`1 See, e.g., Ex. 2002 at 35-36; Ex. 2007.
`
`
`

`
`

`

`
`
`
`
`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`it may be the party or parties at whose behest the petition has been filed.” Id. at 9.
`
`CFAD’s petition here fails to meet this basic, threshold requirement.
`
`The Board is very familiar with the petitioner here. CFAD has filed
`
`numerous petitions requesting inter partes review of pharmaceutical patents. See,
`
`e.g., IPR2015-00720 (Coalition for Affordable Drugs (ADROCA) LLC v. Acorda
`
`Therapeutics, Inc.); IPR2015-01018 (Coalition for Affordable Drugs III LLC v.
`
`Jazz Pharmaceuticals, Inc.); IPR2015-01076 (Coalition for Affordable Drugs IV
`
`LLC et al. v. Pharmacyclics, Inc.); IPR2015-01169 (Coalition for Affordable
`
`Drugs VI LLC et al. v. Celgene Corp.). As has been widely reported, CFAD is a
`
`petitioner for high net worth investors who profit by bringing IPRs. Ex. 2008.
`
`In its Petition, CFAD lists nine real parties in interest. CFAD, however, has
`
`not named IP Navigation Group, LLC (“IP Nav”) and nXn Partners, LLC
`
`(“nXnP”) as real parties in interest. Pet. at 1-2. These two firms are listed as real
`
`parties in interest in a number of other CFAD petitions. See, e.g., Coalition for
`
`Affordable Drugs (ADROCA) LLC v. Acorda Therapeutics, Inc., IPR2015-00720,
`
`Paper 1 at 1-2 (naming IP Nav and nXnP as real parties in interest); Coalition for
`
`Affordable Drugs III LLC v. Jazz Pharmaceuticals, Inc., IPR2015-01018, Paper 1
`
`at 2-3 (same); Coalition for Affordable Drugs V LLC et al. v. Biogen MA Inc.,
`
`IPR2015-01993, Paper 1 at 1-2 (same).

`

`

`
`
`
`
`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`
`Patent Owner has no ability to determine, in CFAD’s intricate web of
`
`subsidiary organizations, whether these two firms are real parties in interest to the
`
`present matter. However, the fact that they appear as real parties in interest in
`
`numerous petitions brought by CFAD, but are absent here, strongly suggests that
`
`CFAD has failed to meet its burden to properly name the real parties in interest to
`
`this case. Atlanta Gas Light Co. v. Bennett Regulator Guards, Inc., IPR2013-
`
`00453, Paper 91 at 7 (P.T.A.B. Feb. 23, 2015) (“. . . [A]s evidenced by the
`
`statutory requirement, the burden of persuasion or proof that the petitioner has
`
`named all real parties-in-interest remains with the petitioner.”) (emphasis in
`
`original). If the Board finds that CFAD has indeed failed to name all real parties in
`
`interest, Patent Owner requests that the Board dismiss the petition as “incomplete.”
`
`37 C.F.R. 42.106(b); ZOLL Lifecor Corp., Case IPR2013-00606, Paper 13 at 16.
`
`IV. THE BOARD SHOULD NOT INSTITUTE IPR BECAUSE CFAD HAS
`NOT CARRIED ITS BURDEN OF DEMONSTRATING A
`LIKELIHOOD THAT THE ʼ268 PATENT CLAIMS ARE
`UNPATENTABLE
`
`CFAD advances two obviousness grounds. In Ground 1, CFAD argues that
`
`claims 1-10 are obvious over the Pink Sheet 2004 in view of Chang. In Ground 2,
`
`CFAD argues that claims 1-10 are obvious over the Stein Presentation or the Stein
`
`Slides (which CFAD collectively calls “Stein 2004”) in view of Chang.
`
`Throughout an inter partes review, “the burden of persuasion to prove
`
`
`
`
`13
`
`

`

`
`
`
`IPR2015-01836
`Patent Owner Preliminary Response
`
`
`unpatentability of the challenged claims remains with the petitioner.” Corning Inc.
`
`
`
`
`v. DSM IP Assets B.V., IPR2013-00053, Paper 66 at 6-7 (P.T.A.B. May 1, 2014).
`
`CFAD has failed to carry its burden of demonstrating that the alleged prior
`
`art renders the claims of the ’268 Patent obvious. Patent Owner therefore
`
`respectfully requests that the Board deny CFAD’s Petition for failing to show a
`
`reasonable likelihood of success in proving that the claims of the ʼ268 Patent are
`
`unpatentable.
