`
`Dear Sir:
`
`L the undersigned, Richard A. Rudick, M.D., residing at 5067 Boulder Creek
`
`Drive, Solon, Ohio 44139-1379, declare and state as follows:
`
`I.
`
`My Background
`
`1.
`
`I am a physician (neurologist), professor and clinical investigator with
`
`a focus on treating patients with neurological diseases. During the last 30 years,
`
`much of my clinical research has focused on multi ple sclerosis ("MS"). Tam Director
`
`of the Mellen Center for Multiple Sclerosis Treatment and Research at the Cleveland
`
`Clinic (since L987), the Vice ChaimJan for Research and Development at the
`
`Neurological Institute at the Cleveland Clinic (since 2007), and a Professor of
`
`Medicine in the Cleveland Clinic Lerner College of Medicine at Case Western
`
`Reserve University (since 2003). 1 served on the Editorial Board of the journal

`
`Multiple Sclerosis - Clinical Issues from 1992 to 2010, and as a member of the
`
`Research Program Advisory Committee at the National Multiple Sclerosis Society
`
`since 2006 ( chajr of the committee since 2009). I am an author or co-author of about
`
`200 peer-reviewed scientific articles, nine (9) books, and more than 40 book chapters
`
`related to MS. A copy of my curriculum vitae accompanies this declaration as
`
`Exhibit A.
`
`2.
`
`I have extensive educational and research experience in the field of
`
`neurologic disorders. 1 currently focus on therapeutic aspects of MS, including
`
`clinical and MRI outcome measures forMS patient care and research. I conducted
`
`pivotal clinical trials involving MS treatments that are now approved by the Food and
`
`Drug Administration. For example, I was an investigator for the Phase 3 clinical
`
`trials involving interferon beta (IFNP-1 a), now marketed as A vonex® . I conducted
`
`MS clinical trials on behalf ofBiogen Idee Inc. ("Biogeo Idee'') in connection with
`
`natalizumab, a parenteral therapy for relapsing-remitting MS (''RRMS"), now
`
`marketed as Tysabri®.
`
`3.
`
`I am fami)jar with U.S. Patent Application No. 13/ 372,426 (filed
`
`February 13, 20 12) entitled "Treatment for Multiple Sclerosis" and the current claims
`
`1n that application, which are directed to methods of treating MS by ad1ninistering
`
`480 mg/day of dimethyl fumarate ("DMF") and/or monomethyl fumarate ("MMF"). I
`
`am also famHiar with the two references cited by the Examiner: U.S. Patent
`
`Publication No. US 2003/0018072 to Joshi et al. ("Joshi"), and Schimrigk et al.,
`
`"Oral fllrnaric acid esters for the treatment of active multip le sclerosis: an open-label
`
`basel ine-contro lied pilot study," European Journal ofNeurology 2006, 13( 6):604-6 .I 0
`
`("Schimrigk").

`
`The Cleveland Clinic (my employer) is being compensated by Biogen
`
`Idee for my services related to this declaration at a rate in accordance with my
`
`standard consu]tation fee. In the past, the Cleveland Clinic (my employer) received
`
`two research grants from Biogen Idee for research studies for which I served as
`
`principal investigator (Exhibit A).
`
`5.
`
`As a physician and an expert in the field of MS, and further as a
`
`clinical investigator, I am qualified to provide an opinion as to what a person of
`
`ordinary skill in the art would have known and concluded as of February 8, 2007, the
`
`priority date for U.S. Patent Application No. 13/3 72,426 ("the time of the invention").
`
`6.
`
`I have been asked by Applicants' attorneys to comment on two areas of
`
`interest in connection with Biogen Idee's investigational drug BG-12, which contains
`
`dimethyl fumarate ("DMF") as the only active ingredient. First, I was asked to
`
`comment on w!hether or not a person of ordinary skjll in the art at the time of the
`
`invention would have reasonably expected a 480 mg/day dose of DMF to be as
`
`efficacious as a 720 mg/day dose of DMF. Second, I was asked to comment on
`
`whether there was a long-fell, but unmet need for oraJ MS therapies at the time of the
`
`invention.
`
`II.
`
`It is unexpected that 480 mg/day ofDMF is as efficacious as 720 mg/day
`
`ofDMF in treating MS
`
`7.
`
`In view of what was publicly known about treating MS with fumarates
`
`at the time of the invention (e.g., the teaching in Schimrigk and the DMF doses used
`
`in the Phase 2 BG-12 clinica[ study), based on my knowledge and experience, I
`
`believe that a person of ordinary skill in the art would have found the magnitude of
`
`the efficacy of the 480 mg/day dose ofDMF, as observed in two recently completed
`

`
`Phase 3 MS clinical studies, to be unexpected (i.e., the 480 mg/day dose was found to
`
`be similarly efficacious as the higher dose of 720 mg/day). The observations
`
`described below form the basis of my opinion.
`
`(tl)
`
`The 480 mgldav dose wtJS unexpectedly efficacious based on
`results trom the Phase 2 clinical studv
`
`8.
`
`In 2004, Biogen Idee initiated a Phase 2 placebo controlled clinical
`
`study of BG-12 (DMF), which emolled 257 patients with RRMS ("the Phase 2
`
`clinical study"). Three doses, ] 20 mg, 360 mg, and 720 mg/day ofDMF, were tested.
`
`See, e.g. , Kappes, L. , et al. , "Efficacy of a novel oral single-agent fumarate,
`
`BGOOOI2, in patients with relapsing-remitting multiple sclerosis: results ofaphase2
`
`study," 16th Meeting of the European Neurological Society (May 30, 2006) (Abstracl)
`
`(Exhibit B); Kappas, L., et al., "Efficacy of a novel oral single-agent Fumarate,
`
`BGOOO 12, in patients with relapsing-remitting multiple sclerosis: results of a pbaseTI
`
`study," 16th Meeting of the European Neurological Society (May 30, 2006) (Slide
`
`Presentation) (Exhibit C); and "Oral Compound BG-12 Achieves Primary Endpoint
`
`in Phase II Study of Relapsing-Remitting MS with BG-12 Led to Statistically
`
`Significant Reductions in MRl Measures," Biogen Idee News Release (May 30, 2006)
`
`(Exhibit D). I am familiar with the results of the Phase 2 study. The study results
`
`show that the 120 mg/day and 360 mg/day doses did not exhibit a statistically
`
`significant difference compared to placebo with respect to the clinical endpoints
`
`measured in the trial (i. e., the mean total number of Gd+ lesions, and the munber of
`
`new and enlarging T -2 hyperintense lesions). The 720 mg/day dose was the only dose
`
`found to have a statistically significant effecl compared to placebo. See figures bdow
`
`which are reproduced from the slide presentation of May 30, 2006 (Exhibit C):

`
`As one can tell from the figures above, the effects seen for different
`
`doses of BG-12 were not clearly dose-proportional (i.e., no suggestion of linear

`
`response). Based on the Phase 2 clinical study results, I believe a person of ordinary
`
`skill in the art at the time of the invention would not have reasonably expected a 480
`
`mg/day dose ofDMF to have similar efficacy as the 720 mg/day dose ofDMF for the
`
`treatment of MS. The person of ordinary skill would have expected that the efficacy
`
`of the 480 mg/day dose to be less than that of the 720 mg/day dose. The fact that the
`
`480 mg/day dose and the 720 mg/day dose, as tested in the Phase 3 clinical studies
`
`(see below), were found to be similarly efficacious is surprising.
`
`10.
`
`BG-12 was subsequently evaluated in two placebo-controlled, double-
`
`blind Phase 3 clinical studies (DEFINE and CONFIRM) ("the Phase 3 clinical
`
`studies"). In both of these Phase 3 clinical studies, it was unexpectedly found that the
`
`480 mg/day dose of DMF has similar efficacy as the 720 mg/day dose of DMF in
`
`treating MS in almost every endpoint measured (i.e. , annualized relapse rate,
`
`proportion of subjects relapsed, number of Gd+ lesions, and progression of disability
`
`at two years). See, e.g., results of the DEFINE study summarized in a Biogen Idee
`
`press release of Apri I I I , 20 II (Exhibit E), results of the CONFIRM study
`
`summarized in a Biogen Idee press release of October 26, 20 ll (Exhibit F), and a
`
`recent Biogeo Idee slide presentation (Exhibit G). See figures 3-5 bel.ow which are
`
`reproduced from Exhibit G.

`
`Results fTOrn an earlier MS clinical study were reported by Schimrigk.
`
`In Schimrigk, investigators administered 1,290 mg/day of a mixture of four
`
`fumarates (six tablets of Fumaderm Forte®) to MS patients in the main treatment
`
`phase.1 According to Schimrigk, the administered fiun arate mixture at this dose was
`
`associated with promising results with respect to certain MS parameters. Even
`
`though DMF is one of the four fumarates in the mixture, the remaining three
`
`fumarates are each an active ingredient. Thus, in my opinion, a person of ordinary
`
`skill in the art would not have reasonably expected DMF by itself to have similar
`
`efficacy in treating MS as four active fumarates (includjng DMF) together. The
`
`1 Schimrigk also discJosed administration oftbree tablets of Fumadenn forte® during a second treatment
`phase (a total of 645 mg/day of fumanltes) and that the eflects from the first treatment phase were maintained.

`
`person of ordinary skill would have even less expectation that 480 mg/day ofDMF
`
`wouJd have similar efficacy as 1,290 mg/day of a mixture of fumarates.
`
`12.
`
`In summary, given that Schimrigk does not provide any teaching or
`
`expectation with regard to DMF dosing and that the results of the Phase 2 clinical
`
`study provides the expectation that 720 mg/day ofDMF is the effective dose forMS
`
`treatment, it wouJd have been highly unexpected by a person of ordinary skill in the
`
`art that 480 mg/day ofDMF is as effective for the treatment ofMS as 720 mg/day of
`
`DMF.
`
`III. BG-12 satisfies a long felt but unsolved need for oral treatment of MS
`
`13.
`
`Over the many years 1 have been treating MS patients and conducting
`
`clini~.:al resear~.:h on MS, I have seen the devastation the disease ~.:an bring. MS is a
`
`chronic autoimmune disease requiring lifelong therapy. The disease affects about 2.5
`
`million people worldwide and has a prevalence that ranges between 2 and 150 per
`
`1 OO,OOOpeople (see e.g., Rosatti, G.,Neurol. Sci. 2001, 22(2): 117-39; Nicholas, R. et
`
`al. , Drug Design, Developmenl and Therapy2011 , 5:255-274). MS is characterized
`
`by inflanunation, myelin destruction, axonal damage and neuronal loss in the central
`
`nervous system. See, e.g., Killestein, J., el a!., "Oral treatment for multiple sclerosis."
`
`Lance/ Neurology 2011, 10:1026-34 ("Killestein") (Exhibit B). Physical and
`
`cognitive impairments of varying degrees are common in MS. The disease is one of
`
`the primary causes for neurological disability in young adults.
`
`A.
`
`There is currently no cure forMS -lifelong treatment is required
`
`14. Not onJy isMS treatable by only a handfi.ll ofMS drugs, but alL but
`
`one of the current disease-modifying drugs for MS require regular injections or
`
`monthly parenteral infusions. I have observed in my patients that administration of
`
`Page 9 of 17

`

`

`
`- 10-
`
`LUKASHEV et al.
`Appl. No. 13/372,426
`
`these medications is often associated with injection anxiety and/or injection-related
`
`adverse effects and limited long-term adherence to treatment. See, e.g., Klauer T.,
`
`and Zettl, U.K., "Compliance, adherence, and the treatment of multiple sclerosis," J.
`
`Neurol. 2008, 255 Suppl 6: 87-92 (Exhibit I); Devonshire, V. et al. , "The Global
`
`Adherence Project (GAP): a multicenter observational study on adherence to disease-
`
`modifying therapies in patients with relapsing-remi tting multiple sclerosis," Eur. J.
`
`Neurol. 2011, 18(1): 69-77 (Exhibit J); M iller, A.E. andRhoades, R.W., "Treatment
`
`ofrelapsing-remittingmultiple sclerosis: current approaches and unmet needs," Curr.
`
`Opin. Neural. 2012, 25 (suppl l ):S4-S I 0 (Exhibit K) , Gold, R., "Oral therapies for
`
`multiple scleroris: a review of agents in phase m development or recently approved,"
`
`CNS Drugs 2011, 25(1): 37-52 (Exhibit L), and Exhibit H. From my personal
`
`experience over many years, it is clear that maintaining adherence to the treatment
`
`regimens is a challenge when providing care forMS patients. Oral MS medications
`
`not only bring significant convenience for patients, but are also expected to greatly
`
`enhance patient compliance and thus are expected to improve long-tenn treatment
`
`benefits compared to injectable MS medications.
`
`15.
`
`A long-felt but unmet need for disease-modifying oral MS medications
`
`has existed for decades. However. at the time of the invention not a single oral drug
`
`for the tTeatment ofMS was available. See, e.g. , "FDA approves first oral drug to
`
`reduce MS relapses,'' Food and Drug Administration News Release (September 22,
`
`201 O) (Exhibit M). A heightened anticipation for disease-modifying oral MS
`
`therapies has existed an1ong health care professionals and patients alike since the fust
`
`disease-modifying MS treatment entered the market (e.g., about 15 years prior to the
`
`Applicants' priority date). As indicated in KiJlestein, "[t]he need for oral drugs for

`
`patients with MS is obvious .... Compliance is poor in many patients because of the
`
`low efficacy and frequent injections." (Killestein, page 1026).
`
`16.
`
`Recently, the first (and currently, the only) oral MS therapy, Gilenya®,
`
`was approved. See, e.g., Exhibit M. However, while providing the advantages of an
`
`oral tTeatment, Gilenya® can cause serious side effects such as "serious infections,
`
`transient reductions in heart rate, vision problems, and respiratory and liver
`
`complications." See, e.g., Sheridan C. Safety profiles come to fore as more drugs
`
`approach MS market. Nat BiotechnoL. 2012, 30(1 ): 6-8 ("Sheridan") (Exhibit N, page
`
`7). For these and other reasons, not every patient can take Gilenya®, leaving many
`
`patients having to rely on injectable drugs. (Exhibit K). Indeed, the US prescribing
`
`infonnation for Gilenya® was recently updated to include patient selection
`
`pararneters as a result ofFDA's review of a reported death upon admin:istTation of the
`
`drug. Thus, additional oral drugs that are safe, effective, appropriate for patients
`
`with comorbidities, and suitable for long-term treatment, are still needed.
`
`B.
`
`BG-12 (DMF) satisfies the long-felt but unsolved need
`
`17.
`
`BG-12 is an oral pharmaceutical formulation, which demonstrated
`
`significant efficacy for the treatment of MS coupled with favorable safety and
`
`tolerability in two pivotal Phase 3 clinical studies. See, e.g., Exhibit E and Exhibit
`
`F. "Results showed that 240 mg ofBG-12, administered either twice or three times a
`
`day, met the primary study endpoint, demonstrating a highly statistically significant
`
`reduction (p<O. 0001) in the proportion of patients with RRMS who relapsed at two
`
`years compared with placebo." (Exhibit E) "BG-12 met the CONFIRM study's
`
`primary endpo1nt by significantly reducing annualized relapse rate (ARR) by 44

`
`percent for BID (p< 0. 0001) and by 51 percent for TID (p< 0. 0001) versus placebo at
`
`two years." (Exhibit F).
`
`18.
`
`The results of the Phase 3 studies have created much excitement for
`
`me and other physicians in this field, as well as analysts of the pharmaceutical
`
`industry for this promising MS treatment. See, e.g., Bloomberg article in response to
`
`CONFIRM data of Oct 26, 2011 ("Bloomberg article") (Exhibit 0 ).

`'confirm' BG-12's
`"These data generally

`with I!:Ji Group in New York, wrote in a note to
`"On a scale of 1-10, with '10'
`clients today.
`being absolute best case, we would put these
`data at perhaps 8 or 9."
`
`/d. (emphasis added).
`
`19.
`
`Furthennore, tbe Food and Drug Administration (FDA) recently
`
`accepted Biogen Idee's New Drug Application (NDA) forBG-12 for the treatment of
`
`MS (see, e.g., Biogen Idee press release dated May 9, 2012, Exhibit P).
`
`20.
`
`There is no question in my mind that once BG-12 becomes available,
`
`it will make a s ignificant difference in the lives of many MS patients. This view is
`
`shared by others in the field. For example, a Decision Resources article ofJune 25,
`
`2012 (Exhibit Q) discloses:
`
`fN} inety-.five percent of all
`surveyed
`neurologists in theEU5[France, Germany, Italy,
`Spain, United Kingdom] expect to prescribe
`BG-12 ....
`
`(emphasis added).
`
`21.
`
`As such, BG-12 at480 mg/day of DMF will contribute significantly
`
`toward meeting the above discussed Long-fell but unmet need for a safe and
`
`efficacious oral MS therapy.

`
`22.
`
`In addition to satisfying the unmet need, there are, in my view, two
`
`additional advantages of the 480 mg/day dose of DMF as compared with the 720
`
`mg/day DMF dose.
`
`(tl)
`
`Two times per tlav (BID) treatment regimen is superior to
`three times per day dosing regimen (TID)
`
`23.
`
`BG-12 at a dose of 480 mg/day DMF is administered using a twice a
`
`day dosing regimen - 240 mg DMF each administration (BID), whereas the other
`
`Phase 3 dose, the 720 mg/day dose, was administered in three doses o£240 mg each
`
`(TID).
`
`24.
`
`BID administration provides a significant advantage over TID
`
`administration because such dosing regimen significantly increases patient
`
`convenience and is expected to increase patient compliance with the treatment
`
`schedule. Increased patient compliance is crucial to achieving maximal benefit from
`
`the drug.
`
`(b)
`
`480 mglday DMF mav provide a Stl{ety advantage (or long(cid:173)
`term treatment
`
`25.
`
`Safety concerns are on the forefront of the scientific discussion for
`
`additional long-term treatment options for MS. Oral drugs that are not only
`
`efficacious, but are characterized by a favorable long-term safety profile have the best
`
`chances of providing long-term benefits toMS patients and are particularly desirable.
`
`See, e.g. , Exhibit L and Exhibit N.
`
`26.
`
`In my opinion, the Phase 3 clinical studies demonstrate an
`
`extraordinary safety/adverse event profile for BG-12 (see, e.g., slide 9 ofExhibit G ).
`
`My opinion is shared by others in the field, including pharmaceutical analysts. For
`
`example, the Bloomberg article discloses

`
`"[t} he most important thing is safety, and the
`safety profile looks exceptional, " Eric Schmidt,
`an analyst with Cowen & Co. in New York, said
`in a telephone interview today.
`"This will
`position BG-12 as a front-line drug. It's hard to
`imagine this won't be a blockbuster."
`
`ld. (emphasis added). Additionally, Sheridan indicates that "some highlight Biogeo
`
`Idee's oral small molecule BG-12 as the pipeline drug with the greatest potential to
`
`reconcile the twin goals of efficacy and safety." (Sheridan at page 6.)
`
`27.
`
`Furthermore, physicians (as well as the FDA and other regulatory
`
`agencies) will prefer the 480 mg/day dose ofDMF given the similar safety/efficacy
`
`profile compared to the 720 mg/day dose. The lower 480 mg/day DMF dose is
`
`expected to offer fewer side effects/adverse events upon administration over a
`
`prolonged period oftime (e.g ., more than the 2-year period designated in each of the
`
`Phase 3 studies) than the similarly effective higher dose of 720 mg/day of DMF
`
`(although the BG-12 clinical studies did not indicate a difference between the safety
`
`profi les of the 480 mg/day and the 720 mg/day dose over two years; see, e.g. , Exhibit
`
`E, Exhibit F, and slide 9 of Exhibit G). Io this sense, 480 mg/day DMF satisfies the
`
`above discussed long-felt need for a safe and efficacious oral MS treatment
`
`particularly well.
`
`28.
`
`In summary, at the Lime of the invention, there had been a long-felt
`
`need for oral therapies forMS, not met for several decades prior to the invention. A
`
`need for safe and efficacious oral MS therapies persists to this current day. 480
`
`mglday ofDMF contributes to meeting this long-felt but unmet need while providing
`
`additional advantages over the similarly effective, higher dose of 720 mg/day.

`
`ln view of the foregoing, I conclude that it would have been
`
`unexpected to a person of ord inary skill at the time of the invention that a 480 mglday
`
`DMF dose is simi larly effective in treating MS than a 720 mg/day DMF dose.
`
`Futthermore, it is my opinion that 480 mg/day (240 mg BID) DMF satisfies a long-
`
`felt, but unmet need for an oral MS therapy.
