`
`
`
`DECLARATION OF MARK J. RATAIN, MD
`
`I, Mark J. Ratain, MD, hereby declare as follows:
`
`I.
`
`INTRODUCTION AND SCOPE OF WORK
`
`1.
`
`I am over the age of eighteen (18) and otherwise competent to make
`
`this declaration.
`
`2.
`
`I have been retained as an expert witness on behalf of Teva
`
`Pharmaceuticals USA, Inc. (“Teva”) and Fresenius Kabi USA, LLC (“Fresenius”)
`
`for the above-captioned inter partes review (“IPR”). I understand that the petition
`
`for inter partes review involves U.S. Patent No. 7,772,209 (“the ’209 patent”),
`
`Exhibit 1001, which issued from U.S. Patent Application No. 11/776,329 (the
`
`“’329 Application”), filed July 11, 2007. (Ex. 1001 at Front Cover.) The ’209
`
`Patent claims priority to U.S. Patent App. No. 60/215,310 (filed June 30, 2000).
`
`The ’209 Patent names Clet Niyikiza as an inventor. The ’209 Patent issued on
`
`August 10, 2010. (Id.)
`
`3.
`
`I served as a testifying expert for Teva and Fresenius in a federal court
`
`action against Eli Lilly and Company involving the ’209 patent, captioned Eli Lilly
`
`and Co. v. Teva Parenteral Medicines, Inc. et al, Case No. 10-cv-1376-TWP-DKL.
`
`The opinions I offered in that litigation have not changed, and they are consistent
`
`with the opinions I set forth and agree to in this declaration.
`
`Teva-Fresenius
`Exhibit 1040-00002
`
`
`
`4.
`
`To prepare this Declaration, I have reviewed the ’209 Patent in light
`
`of general knowledge in the art as of June 30, 1999. In formulating my opinions, I
`
`have relied upon my experience, education and knowledge in the relevant art as
`
`would be relevant to the viewpoint of a person of ordinary skill in the art prior to
`
`June 30, 1999.
`
`5.
`
`I am being compensated for my time in connection with this IPR at
`
`my standard consulting rate, which is $800 per hour for general consulting and
`
`$8000 per day for testimony and preparation for testimony. My compensation is
`
`not contingent on the conclusions I reach herein or on the specifics of my
`
`testimony. I have no financial stake in the outcome of this proceeding.
`
`6.
`
`I understand that the ’209 patent is currently subject to three previous
`
`IPRs, including Neptune Generics, LLC v. Eli Lilly & Co. IPR2016-00237
`
`(“Neptune IPR 1”), Neptune Generics, LLC v. Eli Lilly & Co. IPR2016-00240
`
`(“Neptune IPR 2”), and Sandoz Inc. v. Eli Lilly & Co. IPR2016-00318 (“Sandoz
`
`IPR”). I understand that Petitioners Teva and Fresenius seek to become a party to
`
`each of the foregoing IPRs, and that this declaration is being submitted in
`
`furtherance of specifically Neptune IPR 2.
`
`7.
`
`I have reviewed the materials submitted with the petition filed in the
`
`Neptune IPR 2, including the petition (Paper No. 1), the Declaration of W. Archie
`
`Teva-Fresenius
`Exhibit 1040-00003
`
`
`
`Bleyer, MD, FRCP [GLASG] (filed as Exhibit 1024 in Neptune IPR 2) and
`
`materials cited therein, and the Board’s Decision Instituting Inter Partes Review
`
`(Paper No. 14.) I have also reviewed and considered other documents (such as the
`
`relevant prior art) in arriving at my opinions.
`
`8.
`
`I agree in all material respects with the analysis and opinions set forth
`
`by Dr. Bleyer in his declaration and submitted as Exhibit 1024 in Neptune IPR 2.
`
`Because my independent analysis of the claims and prior art led to the same
`
`substantive conclusions as Dr. Bleyer, coupled with the fact that the Petitioners
`
`Teva and Fresenius are seeking to become a party to the Neptune IPR 2, I adopt
`
`Dr. Bleyer’s substantive opinions as my own. I have appended those opinions after
`
`my signature of this declaration for convenience, and understand that a copy of Dr.
`
`Bleyer’s declaration is being submitted in this IPR as Exhibit 1024.
`
`9.
`
`I understand that in its Decision Instituting Inter Partes Review in
`
`connection with Neptune IPR 2, the Board concluded that Petitioner Neptune
`
`demonstrated a reasonable likelihood of prevailing on its assertion that claims 1-22
`
`of the ’209 patent are unpatentable. Specifically, the Board instituted review on
`
`the following basis: Rusthoven et al., Multitargeted Antifolate LY231514 as First-
`
`Line Chemotherapy for Patients with Advanced Non-Small-Cell Lung Cancer: A
`
`Phase II Study, Journal of Clinical Oncology, Vol. 17, No. 4, (April 1999), pp.
`
`Teva-Fresenius
`Exhibit 1040-00004
`
`
`
`1194-1199 (“Rusthoven”) (Ex. 1011) in view of European Patent Application No.
`
`0,595,005 A1 (“EP 005”). Because Petitioners Teva and Fresenius are seeking to
`
`join Neptune IPR 2, I have limited my opinions in this IPR to the references
`
`discussed in the petition (Paper No. 1) and supporting materials filed in that
`
`proceeding.
`
`II. BACKGROUND AND QUALIFICATIONS
`
`10.
`
`I have been a practicing oncologist since 1986.
`
`11.
`
`I received an M.D. from the Yale University School of Medicine in

`
`
`Teva-Fresenius
`Exhibit 1040-00007
`
`
`
`III. OPINION
`
`20.
`
`I have reviewed and agree with the opinions and conclusions set forth
`
`at Exhibit 1024 of this IPR (which is the declaration of Dr. Bleyer filed in Neptune
`
`IPR 2 at Ex. 1024). For convenience and expediency, I will not reiterate all those
`
`opinions again but instead have appended Dr. Bleyer’s declaration to this
`
`declaration, after my signature.
`
`I am providing no opinions in this IPR beyond
`
`those set forth in Dr. Bleyer’s declaration.
`
`IV.

`
`IV. PERSON OF ORDINARY SKILL IN THE ART
`
`20.
`
`I understand that a person of ordinary skill in the art (“POSA”) is a
`
`hypothetical person presumed to be aware of all pertinent art, understands
`
`conventional wisdom in the art, and is a person of ordinary creativity. In this case,
`
`a medical doctor with an M.D. degree who has significant experience in treating
`
`cancer patients, and a significant understanding of antineoplastic agents, including
`
`antifolates and their efficacies, safety, adverse effects, etc., is a POSA.
`
`21. A POSA may work as part of a multi-disciplinary team and draw upon
`
`not only his or her own skills, but also take advantage of certain specialized skills
`
`of others on the team, to solve a given problem. For example, an expert in
`
`nutrition, an expert in hematology, a basic scientist with expertise in biochemistry,
`
`and a clinician may be part of the team.
`
`V.
`
`THE ’209 PATENT SPECIFICATION
`
`22. This declaration is being submitted together with a petition for inter
`
`partes review of Claims 1-22 of the ’209 Patent.
`
`23.
`
`I have considered the ’209 Patent and portions of file history of the
`
`NEPTUNE GENERICS 1024 - 00007
`
`Teva-Fresenius
`Exhibit 1040-00015
`
`
`
`’209 Patent in light of the general knowledge in the art as of the earliest priority
`
`date of the ’209 Patent—June 30, 1999.
`
`24. The ’209 Patent is titled “Antifolate Combination Therapies,” and
`
`describes and claims “a method of administering an antifolate to a mammal in need
`
`thereof, comprising administering an effective amount of said antifolate in
`
`combination with a methylmalonic acid lowering agent and a FBP [folate binding
`
`protein] binding agent.” (Ex. 1001 at 3:1-5.) The ’209 Patent states that folic acid
`
`is the preferred FBP binding agent, and vitamin B12 is a preferred methylmalonic
`
`acid lowering agent. (Id. at 3:5-6, 4:47-50.)
`
`25. The patent states that antifolates are one of the most thoroughly
`
`studied classes of antineoplastic agents, with a long history, and aminopterin was
`
`the first antifolate that demonstrated clinical activity approximately 50 years ago.
`
`(Id. at 1:19-21.) Shortly thereafter, methotrexate was developed as an anticancer
`
`drug, and today methotrexate is used as a standard chemotherapy drug for several
`
`malignancies, including lymphoblastic leukemia, lymphoma, osteosarcoma, breast
`
`cancer, and head and neck cancer. (See, e.g., id. at 1:22-25.)
`
`26. The patent describes that “[a]ntifolates inhibit one or several key
`
`folate-requiring enzymes of the thymidine and purine biosynthetic pathways, in
`
`particular, thymidylate synthase (TS), dihydrofolate reductase (DHFR), and
`
`glycinamide ribonucleotide formyltransferase (GARFT), by competing with
`
`NEPTUNE GENERICS 1024 - 00008
`
`Teva-Fresenius
`Exhibit 1040-00016
`
`
`
`reduced folates for binding sites of these enzymes.” (Id. at 1:36-41.)
`
`27. The patent states that several antifolate drugs were in development,
`
`and pemetrexed disodium (Alimta®, Eli Lilly and Company, Indianapolis, Ind.)
`
`demonstrated inhibition at several key folate-requiring enzymes such as TS,
`
`DHFR, and GARFT. (Id. at 1:48-49; 1:58-61.)
`
`28. The major limitation of administering antifolates to patients is its
`
`adverse effects on organ and organ system function and of “life-threatening
`
`toxicity.” (Id. at 1:11-12.) For example, “antifolates as a class are associated with
`
`sporadic severe my[e]losuppression with gastrointestinal toxicity which, though
`
`infrequent, carries a high risk of mortality.” (Id. at 1:65-67.)
`
`29. The patent states that increased homocysteine levels have been known
`
`to increase the risk of severe antifolate toxicity in patients, and that folic acid was
`
`known to lower antifolate-induced homocysteine levels. (Id. at 2:14-17, 24-26.)
`
`30.
`
`It further states that antifolate increases methylmalonic acid levels,
`
`which cause toxicity, and the treatment with vitamin B12 reduces such antifolate-
`
`associated toxicity by lowering methylmalonic acid levels. (Id. at 2:41-46.)
`
`31. The patent also states that it was known that folic acid in combination
`
`with vitamin B12 was administered to treat and prevent cardiovascular disease. (Id.
`
`at 50-52.) And, the combination of folic acid and a methylmalonic acid lowering
`
`agent synergistically reduces antifolate toxicity. (Id. at 2:47-50.)

`
`
`
`32. The ’209 Patent’s alleged invention was purportedly conceived “to
`
`lower cytotoxic activity” associated with antifolate treatment. (Id. at 2:29-37.)
`
`33. The ’209 Patent mainly describes: (1) administration of pemetrexed
`
`disodium to a patient in combination with an effective amount of folic acid and an
`
`effective amount of a methylmalonic acid lowering agent, such as vitamin B12; (2)
`
`pretreatment with folic acid prior to pemetrexed disodium treatment; (3)
`
`pretreatment with folic acid and vitamin B12 prior to pemetrexed disodium
`
`treatment; (4) repetition of vitamin B12 administration; and (5) administration of
`
`cisplatin in combination with pemetrexed disodium to the patient. (Ex. 1001 at
`
`10:56-12:29.)
`
`34. The patent acknowledges that a physician determines the amount of
`
`methylmalonic acid lowering agent to be administered based on “the relevant
`
`circumstances, including the condition to be treated, the chosen route of
`
`administration, the actual agent administered, the age, weight, and response of the
`
`individual patient, and the severity of the patient’s symptoms.” (Id. at 5:37-50;
`
`6:41-52.)

`
`B.
`
`The Meaning of Selected Terms in the Claims
`
`57.
`
`It is my understanding that the claim terms in a patent subject to IPR
`
`must be understood to have their broadest reasonable interpretation in light of the
`
`specification of the patent.
`
`58. The terms in the claims of the ’209 Patent are used in accordance with
`
`their plain and ordinary meaning, as exemplified by the terms presented below.
`
`59.
`
`“Patient”
`
`“Patient” means “a human undergoing medical treatment.” (Ex. 1025 at 9.)
`
`60.
`
`“Methylmalonic acid lowering agent”
`
`“Methylmalonic acid lowering agent” means “vitamin B12 or its derivative
`
`that lowers the concentration of methylmalonic acid in a mammal.” (Ex. 1026 at 2;
`
`Ex. 1001 at 4:47-50.)
`
`61.
`
`“An effective amount of pemetrexed disodium”
`
`“An effective amount of pemetrexed disodium” means “an amount of

`
`
`
`
`“An effective amount of folic acid and an effective amount of a

`
`VII. THE STATE OF THE ART AS OF JUNE 30, 1999
`
`A. Antifolates
`
`65. By June of 1999, it was well known in the art that antifolates, such as
`
`pemetrexed, had anticancer properties. (Ex. 1013 at 35; Ex. 1008 at 126.)
`
`66. Antifolates, part of a large class of compounds known as
`
`antimetabolites, inhibit cellular reactions by inhibiting folate-dependent enzymes.
`
`(Ex. 1013 at 35.)
`
`67. As cancer cells actively proliferate, they require large quantities of
`
`DNA and RNA. (Id.) Because antifolates interfere with DNA and RNA synthesis
`
`and cause cell death or stasis, antifolates are used as chemotherapeutic drugs to
`
`treat certain types of cancer. (Id.; Ex. 1014 at 3; Ex. 1011 at 1194; Ex. 1008 at 126;
`
`Ex. 1015 at 99.)
`
`68. By June 1999, several antifolates, such as pemetrexed, methotrexate,
`
`aminopterin, Lometrexol®, 5-fluorouracil, and Tomudex®, were used for the
`
`treatment of, among other diseases, cancer, and autoimmune diseases, including
`
`rheumatoid arthritis and inflammatory bowel disease. (Ex. 1001 at 4:28-44; Ex.
`
`1023 at 9.)
`
`69. However, the major limitation of using these antifolates is that they
