`
`I.
`
`Introduction
`
`1.
`
`I, Richard A. Rudick, M.D., am a medical doctor with expertise in the
`
`field of multiple sclerosis (MS). I have over thirty-five years of experience in MS-
`
`related research, teaching, and clinical practice.
`
`2.
`
`Since 2014, I have been Vice President of Development Sciences,
`
`Value-Based Medicine Group at Biogen. This group focuses on using new
`
`technology to develop innovative programs and tools to better understand,
`
`measure, and manage the treatment of MS.
`
`3.
`
`I am serving as an expert consultant for this inter partes review
`
`proceeding. I am not being compensated for my time beyond my compensation as
`
`a Biogen employee. Neither my employment with Biogen nor my salary is
`
`contingent upon my opinions or the outcome of this or any other proceeding. I
`
`understand that the patent at issue is U.S. Patent No. 8,399,514 (“the ’514 patent”;
`
`Ex. 1001), owned by Biogen.
`
`II. Qualifications
`
`A. Education
`
`4.
`
`I earned my medical doctorate (M.D.) from Case Western Reserve
`
`University School of Medicine in Cleveland, Ohio in 1975. Before that, I earned a

`
`
`
`bachelor of science (B.S.) in zoology from Ohio University in Athens, Ohio in
`
`1971.
`
`5.
`
`From 1975 to 1977, I served as Resident in Medicine at the University
`
`of Connecticut School of Medicine in Farmington, Connecticut. I was Resident in
`
`Neurology at Strong Memorial Hospital in Rochester, New York from 1977 to
`
`1979, and then Chief Resident in Neurology from 1979 to 1980.
`
`B. Research Experience Related to MS
`
`6. My over thirty-five years of experience in research related to MS
`
`includes pivotal clinical trials involving MS treatments that are now approved by
`
`the U.S. Food and Drug Administration (FDA). I was the co-principal investigator
`
`on a National Institutes of Health (NIH)-supported, investigator-initiated clinical
`
`trial of intramuscular recombinant interferon beta (rIFN) for relapsing MS (1990-
`
`1994). This study was supported in part by Biogen, and led to registration of the
`
`rIFN product and marketing under the trade name Avonex®. Over the subsequent
`
`years, I conducted numerous studies on Avonex®, with support from Biogen, the
`
`NIH, and the National MS Society. I was Chairman of the Advisory Committee for
`
`the Biogen-sponsored clinical trial of natalizumab in combination with Avonex®
`
`(the SENTINEL trial, 2002 to 2005). The SENTINEL trial was one of two pivotal
`
`trials of natalizumab that resulted in registration of natalizumab and marketing

`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`under the name Tysabri®. I have conducted many clinical research studies of
`
`natalizumab. I have also participated in many other clinical trials, and in clinical
`
`research protocols in the general field of MS, translational research, outcome
`
`measures, magnetic resonance imaging (MRI), clinical trials, and biomarkers.
`
`7.
`
`I have been awarded dozens of research grants and fellowships
`
`totaling over $170 million, including for “Evaluating Selected Monitoring
`
`Techniques in MS Clinical Trials” from the National MS Society ($118,852 from
`
`1989 to 1990), “IM Recombinant Beta Interferon as Treatment for MS” from the
`
`NIH ($4,200,000 from 1990 to 1994), “Monitoring Brain Atrophy During the
`
`Course of MS” from the NIH ($1,303,967 from 1999 to 2004), and “Biomarkers of
`
`the Therapeutic Response to Interferon in MS” from the NIH ($1,106,015 from
`
`2004 to 2009). I have also received research grants and fellowships from
`
`pharmaceutical companies, including two from Biogen ($70,000 from 1993 to
`
`1995 and $624,900 from 1994 to 2001). I was co-principal investigator on two
`
`cycles of a grant to Case Western Reserve University School of Medicine, the
`
`Cleveland Clinical and Translational Research Collaborative (CTRC) ($64,000,000
`
`from 2007-2012; and $64,600,000 from 2012-2017). The purpose of this grant was
`
`to establish educational programs for clinical and translational research, and
`
`infrastructure to accelerate clinical research progress across the medical institutions

`
`
`in Cleveland, Ohio. This grant covered research in neurology as well as many other
`
`fields. I transitioned to Biogen in 2014, prior to completion of the second cycle of
`
`this grant.
`
`8.
`
`I was Director of the Mellen Center for MS Treatment and Research
`
`at the Cleveland Clinic from 1987 to 2014. During this time, I also served as
`
`Chairman of the Division of Clinical Research at the Cleveland Clinic (2001-
`
`2007), Vice-Chairman of Research and Development at the Neurological Institute
`
`at the Cleveland Clinic (2007-2014), and Co-Director of the Cleveland CTSC
`
`(2004-2014).
`
`C. Teaching Experience Related to MS
`
`9. My over thirty-five years of experience teaching others about MS
`
`includes teaching at the Rochester University School of Medicine as Instructor in
`
`Neurology (1979-1980), Assistant Professor of Neurology (1980-1986), Associate
`
`Professor of Neurology (1986-1987), and Adjunct Associate Professor of
`
`Neurology (1987-1995).
`
`10. From 1995 to 2014, I was Hazel Prior Hostetler Professor of
`
`Neurology at the Cleveland Clinic. I was also Professor in the Department of
`
`Medicine, Primary Appointment, in the Cleveland Clinic Lerner College of
`
`Medicine (CCLCM) from 2003 to 2014, and Professor in the Department of

`
`
`
`General Medical Sciences and Center for Clinical Investigation in the Case School
`
`of Medicine from 2006 to 2014. I have trained dozens of students, neurology
`
`residents, and post-doctoral research fellows, many of whom are now leaders in the
`
`field of MS.
`
`D. Clinical Experience Related to MS
`
`11. My over thirty-five years of clinical experience with MS includes
`
`diagnosing and treating many thousands of patients with MS, including patients
`
`who have been referred to me from physicians all over the world. I diagnosed and
`
`treated MS patients as an Associate Neurologist at Strong Memorial Hospital from
`
`1980 to 1987. I also had clinical experience at the Mellen Center, where I
`
`diagnosed and treated patients with MS from 1987 to 2014. In addition to my own
`
`medical practice and providing ongoing clinical care and consultation to other
`
`physicians, I also supervised a medical staff of eleven other neurologists who
`
`specialized in MS and worked full-time at the Mellen Center, and seven advanced
`
`practice clinicians (master’s prepared nurses and physician assistants). In 2013, my
`
`last full year at the Mellen Center, over 5,000 individual patients were evaluated or
`
`treated.
`
`12.
`
`I was certified by the American Board of Internal Medicine in 1978
`
`and by the American Board of Psychiatry and Neurology in 1981.

`
`
`
`E. Additional Experience and Qualifications
`
`13.
`
`I have authored over 230 peer-reviewed publications related to MS. I
`
`have also held editorial positions on journals including Neurotherapeutics, Lancet
`
`Neurology, and Multiple Sclerosis - Clinical Issues. I have authored ten books and
`
`over thirty book chapters, including several editions of Multiple Sclerosis
`
`Therapeutics (Martin Dunitz Publishers, London 1st ed. 1999; Martin Dunitz
`
`Publishers, London 2nd ed. 2003; Informa Healthcare, Oxon 3rd ed. 2007;
`
`Cambridge University Press, New York 4th ed. 2011).
`
`14.
`
`I have given over seventy invited lectures related to MS, including
`
`“Three Decades of MS Research: What We Have Learned, Where We Are Going”
`
`at the National Board of Directors Meeting of the National MS Society in 2007,
`
`and “MS Functional Composite: What Works and What Doesn’t Work” at the
`
`International Conference on Disability Outcomes in MS in 2011.
`
`15. Since 2007, I have been engaged as an expert consultant for
`
`pharmaceutical companies, including Biogen (National Faculty Meeting (2008);
`
`European Committee for Treatment and Research in MS (ECTRIMS) Meetings
`
`(2008, 2013); National Consultant Meetings (2009, 2010, 2011); Advisory Board
`
`Meeting (2009); Avonex® Biomarker Advisory Board Meeting (2010); National

`
`16.
`
`I have been a member of a dozen or so professional societies,
`
`including the American Academy of Neurology, the American Association for the
`
`Advancement of Science, the American Association of Physicians, and the
`
`American Neurological Association. I have served on over a dozen committees and
`
`advisory boards, including research peer-review committees for the National MS
`
`Society, the NIH, and the MS International Federation. I have served on and also
`
`chaired the National MS Society Research Program Advisory Committee, the NIH
`
`Council for the National Council for Research Resources, and the NIH Council of
`
`Councils. I currently co-direct the MS Outcomes Assessment Consortium
`
`(MSOAC), under the aegis of the Critical Path Institute. MSOAC, sponsored by
`
`the National MS Society, is a collaboration of eight pharmaceutical companies, MS
`
`academic leaders from around the world, the FDA, and European Medicines
`
`Agency (EMA). The goal of MSOAC is to establish an improved clinical outcome
`
`measure for MS disability, in order to accelerate progress in treating progressive
`
`forms of MS.
`
`17.
`
`I have received many awards for my work related to MS, including
`
`the Alfred and Norma Lerner Humanitarian Award (the Cleveland Clinic’s most

`
`from the National MS Society.
`
`18. My curriculum vitae (Ex. 2045) provides further information about
`
`my experience and qualifications.
`
`III. Documents Considered
`
`19. My opinions are based on my knowledge and experience. In forming
`
`my opinions, I have also considered the documents listed in Appendix A, attached
`
`to this declaration.
`
`IV. Overview of MS
`
`20. MS is a chronic, unpredictable, and often disabling disease of the
`
`central nervous system (CNS). MS was first detected in the 1800s and became a
`
`common diagnosis by the early 1900s. (Ex. 2065 at 3.) By the 2007 filing date of
`
`the ’514 patent, MS affected about 2.5 million individuals worldwide. (Ex. 2065 at
`
`3, 221.)
`
`21. The CNS, which includes the brain, optic nerves, and spinal cord, is
`
`responsible for transmitting information within the brain and between the brain and
`
`the body. This transmission of information is accomplished by neurons, which are
`
`nerve cells that process and transmit information through electrical and chemical
`
`signals. Each neuron consists of a cell body, an axon, and dendrites (see figure
`
`9
`
`Page 9 of 36
`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`below). Axons are nerve fibers that are covered with a fatty substance known as
`
`myelin (or myelin sheath). Myelin serves to maintain the health of the axons, and
`
`to speed the transmission of information along the axons. Myelin is essential for
`
`normal CNS function.
`
`
`
`22. The cause of MS is not known, but scientists believe that the
`
`
`
`interaction of immunologic, environmental, and genetic factors are involved. It is
`
`believed that the immune system attacks healthy tissue in the CNS in certain
`
`individuals, leading to damaged or destroyed myelin, oligodendrocytes (the cells
`
`that produce myelin), and the underlying axons. This in turn leads to damaged
`
`areas along the nerve (lesions or scars), slowing or stopping the transmission of
`
`information necessary for normal thinking and bodily function.
`

`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`23. MS can adversely affect nearly any bodily function. Symptoms of MS
`
`are unpredictable and vary in type and severity from one person to another and in
`
`the same person over time. Symptoms may disappear completely, may improve but
`
`only partially, or may steadily worsen over time. As the illness advances, repeated
`
`immune-mediated inflammatory attack on different parts of the CNS leads to
`
`increasing symptom burden. Symptoms may include numbness, tingling, walking
`
`difficulty, tremors, slurred speech, memory problems, concentration problems,
`
`spasticity, bladder problems, sexual dysfunction, weakness, pain, fatigue, blurred
`
`vision, blindness, loss of balance, poor coordination, or paralysis.
`
`24. The progress and severity of MS in an individual are also
`
`unpredictable. Most people diagnosed with MS have relapsing-remitting MS
`
`(RRMS) at disease onset. In RRMS, people experience clearly defined attacks of
`
`new or increasing neurologic symptoms (relapses or exacerbations) followed by
`
`periods of partial or complete recovery (remissions). Over time, RRMS in most
`
`people transitions to a pattern of progressive worsening with few or no relapses
`
`(secondary progressive MS or SPMS). Some people diagnosed with MS have
`
`primary progressive MS (PPMS) at disease onset. In PPMS, people demonstrate a
`
`steady progression of symptoms from the time of diagnosis onward.

`Declaration of Richard A. Rudick, M.D.
`
`
`
`25. MS can be difficult to diagnose, so the diagnosis should be made by,
`
`or confirmed by, a neurologist who is knowledgeable about MS. MRI scans are
`
`generally used to detect damaged areas of the nerve (lesions or scars) to aid in the
`
`diagnosis.
`
`26. MRI scans are also used to monitor MS. Because not all damaged
`
`areas of the nerve produce symptoms, MRI scans may detect disease activity that is
`
`not otherwise apparent to the patient or the healthcare provider. MRI is an
`
`important outcome measurement in MS drug research to determine the effect of a
`
`drug on MS.
`
`27. MRI methods include detecting MS lesions using T2 weighted and T1
`
`weighted images. MS lesions detected with T2 weighted imaging appear as bright
`
`spots compared with the surrounding tissue in the white matter of the brain and
`
`spinal cord. These lesions have variable underlying pathology changes, ranging
`
`from minimal to severe tissue damage. Once a T2 lesion develops, it generally
`
`persists for many years. T1 weighted imaging reveals MS lesions that appear dark
`
`compared with the normal surrounding tissue. MS lesions detected by T1 weighted
`
`images are more severe, reflecting underlying tissue damage. An MRI contrast
`
`agent, gadolinium, is used to identify new or very recent MS lesions. When
`
`combined with T1 weighted images, after injection of gadolinium, new lesions
`
`12
`
`Page 12 of 36
`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`appear as bright spots compared with surrounding tissue. These gadolinium-
`
`enhancing (Gd+) lesions indicate active and recent inflammation. Gd+ lesions
`
`disappear about six weeks after they appear, because the blood brain barrier, which
`
`opens at the time of new lesion formation, closes, excluding the gadolinium
`
`contrast agent from the brain tissue. As opposed to Gd+ lesions, T2 bright lesions,
`
`appearing in the same location as Gd+ lesions, persist for long periods of time.
`
`28. Analysis of MS lesions has been crucial to the development of
`
`treatments for MS, because when a treatment reduces new lesion formation
`
`detected by MRI in a small group of MS patients, it predicts beneficial effects on
`
`relapses in larger clinical studies. This is because the treatment effect on lesions is
`
`linked to the treatment effect seen on relapses, but is much more sensitive,
`
`meaning this benefit can be observed in far fewer patients. The magnitude of the
`
`benefit on new MRI lesion formation (the MRI effect size) correlates very well
`
`with the magnitude of benefit on clinical relapses (the clinical effect size). MS
`
`lesions are only part of the story, however, because brain tissue that appears
`
`normal using standard MRI imaging is abnormal when more advanced MRI
`
`techniques are used, such as magnetization transfer ratio (MTR) or diffusion tensor
`
`imaging (DTI). Also, demyelinated lesions in gray matter areas of the brain (e.g.
`
`the cerebral cortex, the thalamus) are not visible using routine MRI scans, so MS
`
`13
`
`Page 13 of 36
`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`pathology in the gray matter requires the use of precise techniques to measure the
`
`volume of the brain. Using these very precise computer programs, it has become
`
`clear that the size of the brain, both the white matter and the gray matter, in MS is
`
`lower than healthy people of the same gender and age, and that the brain in MS
`
`shrinks much faster than it does in healthy aging people. Brain shrinkage is
`
`commonly referred to as brain atrophy, and MRI techniques to measure brain
`
`atrophy have become standard in MS clinical trials. The benefit of a drug in
`
`slowing brain atrophy has been shown to correlate with the benefit of the same
`
`drug in slowing MS-related disability worsening.
`
`29. No cure exists for MS. The FDA has approved certain medications
`
`that modify the course of MS by reducing the number of relapses and delaying
`
`progression of disability to some degree. This category of medication is referred to
`
`as disease-modifying therapy. Disease-modifying therapy implies that the
`
`treatment lowers the overall advance of MS, lessening the overall impact the
`
`disease has on the MS patient over time. Disease modification is the key treatment
`
`objective for the MS field, because the impact of MS over time is so terrible.
`
`Lengthening the amount of time an individual with MS can work, participate in
`
`normal activities, maintain social roles, and remain independent is important to
`
`14
`
`Page 14 of 36
`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`every MS patient, and to society at large, and these long-range benefits are the
`
`goals of MS disease modifying therapy.
`
`30. The FDA has also approved certain medications to help patients
`
`manage some symptoms that occur commonly in MS, such as fatigue, depression,
`
`stiffness, or bladder control. These treatments are very useful for people with MS,
`
`because they can lessen symptoms that lower quality of life. This category of
`
`treatment is called “symptomatic therapy.” Symptomatic therapy is very different
`
`from disease-modifying therapies, because symptomatic therapies do not change
`
`the underlying pathological process, do not diminish the amount of CNS damage
`
`and deterioration, and do not interfere with the long-term consequences of the
`
`neurological damage – disability related to cognitive, visual, sensory, motor,
`
`autonomic, sexual, and bowel/bladder impairment. Symptomatic therapies can be
`
`tested in short-term clinical trials over two or three months, because the onset of
`
`the benefit is rapid, and the offset is rapid. Often, the treatment benefit is obvious
`
`for individual patients within the trial of symptom therapy. In contrast, testing
`
`disease-modifying therapy generally requires years.
`
`31. As of the 2007 filing date of the ’514 patent, no safe and effective oral
`
`disease-modifying medications were approved for MS. Injection MS medications
`
`were available, but they required regular injections or monthly parenteral infusions
`
`15
`
`Page 15 of 36
`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`and had significant limitations. For many patients, these injectable MS medications
`
`were often associated with injection anxiety or injection-related adverse effects,
`
`limiting long-term adherence to treatment, and leading to many patients declining
`
`to use disease-modifying therapy entirely.
`
`32. On March 27, 2013, the FDA approved Tecfidera® (dimethyl fumarate
`
`(DMF)) capsules for the treatment of patients with relapsing forms of MS.
`
`Tecfidera® is an oral medication administered twice a day as capsules containing
`
`240 mg of DMF, for a total daily dose of 480 milligrams (mg) of DMF. Tecfidera®
`
`falls into the disease-modifying category of MS medications.
`
`33. Before Tecfidera® entered the market, the MS community was
`
`excited. MS patients and physicians were generally aware of two Phase 3 studies
`
`demonstrating that a pharmaceutical preparation of DMF (known as BG-12 or
`
`BG00012 at the time) given in a dose of 480 mg/day was a safe and effective oral
`
`disease-modifying medication for MS. In July 2012, I wrote a declaration about the
`
`unexpected and promising results that these clinical studies demonstrated.
`
`(Ex. 2011.) That declaration was submitted to the U.S. Patent and Trademark
`
`Office as part of the application that became the ’514 patent. I was not employed
`
`by Biogen when I wrote that declaration. I believed that the results shown in the
`
`two Phase 3 studies were unexpected and that Tecfidera® would make a significant
`

`
`
`
`U.S. Patent No. 8,399,514
`Case: IPR2015-01993
`Declaration of Richard A. Rudick, M.D.
`
`
`
`difference in the lives of many MS patients. (Ex. 2011 at 12.) The opinions that I
`
`expressed in my 2012 declaration hold true today, as discussed further below.
`
`V. The ’514 Patent and Level of Ordinary Skill in the Art
`
`34. The ’514 patent claims are directed to methods for treating MS by
`
`administering DMF, monomethyl fumarate (MMF), or a combination thereof in a
`
`therapeutically effective amount of about 480 mg/day. As discussed above,
`
`Tecfidera® is an oral medication for the treatment of MS that is administered at a
`
`dose of 480 mg/day of DMF.
`
`35.
`
`I understand that certain legal issues, such as claim construction and
`
`obviousness, are determined from the viewpoint of a person of ordinary skill in the
`
`art. I understand that a person of ordinary skill is a hypothetical person who is
`
`presumed to have known the relevant art at the time of the invention.
`
`36.
`
`I understand that Biogen has taken the position that a person of
`
`ordinary skill in the art in 2007 would have had at least a medical degree with at
`
`least three years of training in neurology and at least three years of clinical
`
`experience treating MS. I think that this is a reasonable position because the ’514
`
`patent is directed to treating MS. I am qualified to provide an opinion as to what a
`
`person of ordinary skill would have known and concluded as of the 2007 filing
`
`date of the ’514 patent.

`VI. The Claimed Invention Achieved Unexpected Results
`
`37.
`
`I understand that one indicator that a claimed invention would not
`
`have been obvious to a person of ordinary skill at the time of the invention is if the
`
`claimed invention achieved unexpected results. In my opinion, the claimed
`
`invention of the ’514 patent achieved unexpected results.
`
`38.
`
`I have considered Kappos et al., 16th Meeting of the European
`
`Neurological Society (abstract to presentation May 30, 2006) (“Kappos 2006”)
`
`(Ex. 1003A) and the accompanying Kappos et al. presentation at the 16th Meeting
`
`of the European Neurological Society (May 30, 2006) (“Kappos presentation”)
`
`(Ex. 1007 at 55-77). The Kappos 2006 abstract and Kappos presentation relate to a
`
`Phase 2 placebo-controlled clinical study of a pharmaceutical preparation known
`
`as BG-12 that contained DMF. (Ex. 1003A at 27.) In addition to a placebo arm,
`
`three doses of DMF were tested in MS patients: 120 mg/day, 360 mg/day, and
`
`720 mg/day. (Ex. 1003A at 27.)
`
`39. The primary clinical endpoint measured in the trial was the mean total
`
`number of Gd+ lesions seen on MRI scans at weeks 12, 16, 20, and 24. (Ex. 1003A
`
`at 27.) Gd+ lesions indicate new lesions, formed within the prior six weeks, and, as
`
`discussed above, are a measure used to determine the inflammatory activity within
`
`an individual MS patient. Secondary endpoints included the number of new and
`

`
`
`
`enlarging T2 hyperintense lesions at week 24. (Ex. 1003A at 27.) New and
`
`enlarging lesions represent all of the lesions that have developed or enlarged since
`
`the beginning of the study.
`
`40. The Phase 2 study results showed that both the 120 mg/day and
`
`360 mg/day doses did not exhibit a statistically significant difference compared to
`
`placebo for either of these clinical endpoints. (Ex. 1007 at 67, 69.) For
`
`new/enlarging T2 lesions, the results with these doses were nearly identical to
`
`those with placebo. (Ex. 1007 at 69.) In contrast, the 720 mg/day dose showed a
`
`statistically significant effect compared to placebo for both of these clinical
`
`endpoints. (Ex. 1007 at 67, 69.) The benefits of this 720 mg/day dose were not just
`
`statistically significant, they demonstrated an impressive magnitude of benefit –
`
`69% reduction in the number of Gd+ lesions, and 48% reduction in the number of
`
`new and enlarging T2 lesions. (Ex. 1007 at 67, 69.) From a clinical perspective,
`
`this is considered a very strong benefit. These Phase 2 results are depicted in
`
`Figures 1 and 2 below (copied from my previous declaration, Ex. 2011 at 5).

`
`
`
`41. The results of the Phase 2 study were not dose-proportional and there
`
`was no hint of a linear dose response. A person of ordinary skill would not have
`
`known what effect, if any, a particular dose of DMF between 360 mg/day and 720
`
`mg/day might have demonstrated based on the Phase 2 results. Such person
`
`reviewing the Phase 2 results likely would have selected a dose of 720 mg/day for
`
`further investigation because only that dose was shown to be effective in the study.
`
`42. Based on the Phase 2 results, a person of ordinary skill would have
`
`had no reason to select a dose of 480 mg/day of DMF for further study. To the
`
`contrary, based on the Phase 2 results, a person of ordinary skill would have at
`
`most expected that the efficacy of a 480 mg/day dose would be more like that of
`
`the 360 mg/day dose (which was not effective) than that of the 720 mg/day dose
`
`(which was effective). This is because a 480 mg/day dose is closer to a 360 mg/day
`
`dose than a 720 mg/day dose.
`
`43. The DMF pharmaceutical preparation (BG-12) was subsequently
`
`evaluated in two placebo-controlled, double-blind Phase 3 clinical studies (called
`
`DEFINE and CONFIRM). I have considered the published reports of these studies:
`
`Gold et al., N. Engl. J. Med. 367(12):1098-107 (2012) and Supplementary
`
`Appendix (“DEFINE publication”) (Ex. 2025) and Fox et al., N. Engl. J. Med.
`
`367(12):1087-97 (2012) and Supplementary Appendix (“CONFIRM publication”)

`
`
`
`(Ex. 2026). In addition to a placebo arm, these studies tested two doses of DMF in
`
`MS patients: 480 mg/day (BG-12 BID) and 720 mg/day (BG-12 TID). (Ex. 2025 at
`
`1; Ex. 2026 at 1.)
`
`44. The DEFINE study’s primary endpoint was the proportion of MS
`
`patients who had a relapse by two years. (Ex. 2025 at 1.) Other endpoints included
`
`annualized relapse rate, the number of new and enlarging T2-weighted lesions, the
`
`number of Gd+ lesions, and confirmed progression of disability. (Ex. 2025 at 1.)
`
`For each of these endpoints, the results with the 480 mg/day dose were statistically
`
`significantly better than those with placebo. (Ex. 2025 at 6.) Moreover, the results
`
`with the 480 mg/day dose were similar to those with the 720 mg/day dose for each
`
`endpoint measured. (Ex. 2025 at 6.)
`
`45. The CONFIRM study’s primary endpoint was annualized relapse rate
`
`over two years. (Ex. 2026 at 1.) Other endpoints included the proportion of
`
`patients who had a relapse by two years, the number of Gd+ lesions, the number of
`
`new and enlarging T2-hyperintense lesions, the number of new T1 hypointense
`
`lesions, and progression of disability. (Ex. 2026 at 1.) For each of these endpoints
`
`except the progression of disability, the results with the 480 mg/day dose were
`
`statistically significantly better than those with placebo. (Ex. 2026 at 7.) Moreover,
`

`
`
`
`the results with 480 mg/day were similar to those with the 720 mg/day dose for
`
`each endpoint measured. (Ex. 2026 at 7.)
`
`46. These DEFINE and CONFIRM Phase 3 results are summarized in
`
`Figures 3, 4, and 5 below (copied from my previous declaration, Ex. 2011 at 7-8).
`
`Figure 3 shows that the annualized relapse rate with 480 mg/day was similar to that
`
`with 720 mg/day. (Ex. 2011 at 7.) Figure 4 shows that the disability progression
`
`with 480 mg/day was similar to that with 720 mg/day. (Ex. 2011 at 7.)

`
`Figure 4. Disability Progression at Two Years. The results with 480 mg/day
`
`(BG-12 BID) and 720 mg/day (BG-12 TID) were only statistically
`
`significant against placebo in the DEFINE study, but they were similar to
`
`
`
`each other in both studies. (Ex. 2011 at 7.)
`
`47. Figure 5 directly compares the effects of 480 mg/day, 720 mg/day,
`
`and placebo on multiple different endpoints. It represents a pool of the results from
`
`the DEFINE and CONFIRM studies. In this figure, the dashed line indicates no
`
`difference at all of the treatment compared with placebo. The distance to the left of
`
`the dashed line indicates the magnitude of the benefit on that particular outcome
`
`compared with placebo. For example, an outcome result at the 0.5 level means that
`
`the treatment is twice as good as placebo. An outcome result at the 2.0 level means
`
`that the treatment is half as good as placebo. As is evident from Figure 5, BG-12

`
`
`has beneficial effects on every single outcome tested; furthermore, 480 mg/day has
`
`similar efficacy to 720 mg/day on every outcome.

`
`could not have predicted, the Phase 3 results based on the Phase 2 results. The
`
`Phase 2 study showed that 120 mg/day and 360 mg/day doses were ineffe
