`
`I, Fred Lublin, M.D., declare as follows:
`
`
`
`Introduction and Summary
`1.
`I previously submitted a declaration in this proceeding on May 2, 2017,
`
`Exhibit 2003. I respectfully incorporate that declaration by reference. I use the same
`
`abbreviations and terms here that I used there. I submit this new declaration to
`
`provide information about fingolimod’s clinical trials.
`
`2.
`
`I have been involved in clinical trials for almost every MS medication
`
`approved in the U.S. and Europe as of June 2006 and thereafter, as well as many that
`
`were never approved. I was involved in both the Phase II and Phase III human trials
`
`for fingolimod, as I describe further below.
`
`3.
`
`The Phase III trial for fingolimod tested two doses, 1.25 mg and 0.5 mg
`
`daily. Counsel for Novartis has asked me whether the 0.5 mg dose was expected to
`
`be effective. The answer is no. I and others believed the likelihood was that 0.5 mg
`
`daily would be equivalent to placebo, i.e., that it would show no efficacy. Even if it
`
`showed some efficacy, I am aware of no one who believed that dose would have the
`
`same efficacy as 1.25 mg daily. I was very surprised when 0.5 mg daily produced
`
`essentially the same results as that higher dose.
`
`4.
`
`As I describe below, fingolimod’s earlier Phase II MS trial had also
`
`tested two doses, 5.0 mg and 1.25 mg daily. Pre-clinical and clinical studies had
`
`suggested that fingolimod’s efficacy was dose-dependent. I and others therefore
`
`
`
`1
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`expected the 5.0 mg dose to be more effective than the 1.25 mg dose. We were
`
`surprised when the two Phase II doses showed essentially the same efficacy.
`
`Because the lower 1.25 mg daily dose had also shown slightly better safety, Novartis
`
`proposed to the U.S. FDA to confirm that dose’s efficacy in Phase III studies.
`
`5.
`
`FDA agreed to a Phase III trial for 1.25 mg daily but asked Novartis to
`
`evaluate a lower dose too. At the time, a recent incident involving another drug
`
`called “Tysabri” had prompted FDA to express extra concern about the safety of MS
`
`medications. FDA accordingly pressed to understand fingolimod’s minimum
`
`effective dose. That would allow FDA and others to understand fingolimod’s
`
`optimal balance between efficacy and safety.
`
`6.
`
`Novartis included a 0.5 mg dose arm in the Phase III trials, but adopted
`
`a novel MS trial design to account for the scenario that a 0.5 mg daily dose would
`
`not be effective. A panel was tasked to conduct an early analysis of patients given
`
`0.5 mg daily to evaluate if the dose was “futile” and should be discontinued before
`
`the full trial was finished. I have never been involved in a Phase III MS clinical trial
`
`that contained such an early “futility analysis” of one dose and not others.
`
`7.
`
`Notwithstanding that feature of the Phase III trials, physicians remained
`
`concerned that 0.5 mg daily would be ineffective. A review panel at my own hospital
`
`Mount Sinai in New York City balked at participating in one of the trials for fear
`
`that the 0.5 mg dose would be no more effective than placebo.
`
`
`
`2
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`It thus came as a total surprise when 0.5 mg daily proved to be not only
`
`8.
`
`effective, but essentially just as effective as 1.25 mg daily. That unexpected result
`
`meant that FDA still did not have enough information to know fingolimod’s
`
`minimally-effective dose. FDA accordingly approved fingolimod on condition that
`
`Novartis conduct a post-marketing “Phase IV” study of an even lower dose, which
`
`ended up to be 0.25 mg daily. That study’s results are not yet available. In addition,
`
`others in the field conducted further experiments in search of fingolimod’s dose-
`
`response curve in smaller studies that I describe below. If fingolimod’s efficacy at
`
`0.5 mg daily would have been obvious in June 2006, then FDA and Novartis would
`
`have started testing these lower doses at the outset, rather than wait until after the
`
`Phase III trial.
`
`9.
`
`I describe these facts in more detail in the paragraphs to follow. I first
`
`summarize my experience with MS clinical trials generally. I then describe the
`
`fingolimod clinical trials, including a background on MS clinical trials and a
`
`description of the fingolimod Phase I-III trials as well as post-marketing research.
`
`10.
`
`I was first retained to provide expert advice on Gilenya®-related
`
`litigation in April 2015. In preparing my testimony in this declaration, I have worked
`
`approximately 62 hours, including many hours conducting my own research into the
`
`prior art. I have spoken with counsel and reviewed and commented upon drafts they
`
`prepared based on our discussions. I have thoroughly reviewed the contents of my
`
`
`
`3
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`final declaration and believe this document accurately sets forth my views. I reserve
`
`the right to amend any part of my testimony in the event of new information brought
`
`to my attention.
`
` My Clinical Trial Experience
`11. As my first declaration describes (Ex. 2003 ¶¶ 8-16), I currently am a
`
`Professor of Neurology and the Director of the Corinne Goldsmith Dickinson Center
`
`for Multiple Sclerosis at the Icahn School of Medicine at Mount Sinai, and Attending
`
`Neurologist at Mount Sinai Hospital in New York City. Mount Sinai is a teaching
`
`hospital where we not only treat patients, but also conduct independent research.
`
`Currently Mount Sinai hosts two laboratories run by Ph.D. biologists conducting
`
`original basic science research into multiple sclerosis.
`
`12. My CV (Ex. 2004) identifies 35 MS drug clinical trials in which I have
`
`been Principal Investigator and some where I was Co-Investigator in the “Research
`
`Grants” section beginning on Page 11. I have also served as Principal or Co-
`
`Investigator on trials not listed in my CV. Principal Investigators are typically
`
`responsible for designing trials, supervising their progress, and reporting on their
`
`results. Among other tasks, this includes developing the statistical methods used to
`
`evaluate the results, and making judgments about the doses to be tested. Co-
`
`Investigators share the same functions in a group of two or more. In addition, my
`
`publication list identifies 24 trials in which I have served as an advisor and/or author
`
`
`
`4
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`on papers describing clinical trial results, some of which may overlap with trials in
`
`which I was a Principal or Co-Investigator. I list those references in the footnote
`
`below.2 I also served on steering or safety committees for these agents.
`
`13. Among the drugs for which I have served these roles include all the
`
`medicines approved to treat RRMS as of June 2006, such as (1) various forms of
`
`interferon-beta (such as “Betaseron®”), the first-ever approved “disease modifying
`
`therapy” (DMT) for MS; (2) glatiramer acetate, an approved DMT sold under the
`
`brand name “Copaxone®”; (3) mitoxantrone, another approved DMT sold under the
`
`name “Novantrone®”; natalizumab, a DMT sold under the brand-name “Tysabri®”;
`
`plus various studies of corticosteroids for treating inflammation and symptoms in
`
`MS.
`
`14.
`
`In addition to serving as a Principal Investigator, Co-Investigator, or
`
`advisor and co-author on papers related to clinical trials, I have also regularly served
`
`on clinical trial Data Safety Monitoring Boards (DSMBs), also called Data
`
`Monitoring Committees (DMC). DSMBs are panels of physicians responsible for
`
`monitoring safety data as it becomes available during a clinical trial. In the event a
`
`serious safety issue emerges, DSMBs will advise the drug sponsor on whether to

`U.S. Patent No. 9,187,405
`adjust the trial, including possibly by ending it. I estimate that I have served on 7
`
`DSMBs in my career for clinical trials involving potential MS drug therapies.
`
`15. Given my experience in MS clinical trials, I have also written papers
`
`about MS drug trial design, such as those listed at entries 99, 120, and 157 in my
`
`CV.
`
` The Fingolimod Clinical Trials
`16. Novartis conducted its fingolimod clinical trials at a unique time in the
`
`development of MS medications. Several DMTs were already available in the
`
`marketplace. One of those DMTs, Tysabri, had developed serious safety issues in
`
`the middle of Novartis’s clinical trial program for fingolimod. These facts posed
`
`special challenges for the fingolimod Phase III MS trials, as I discuss further below.
`
`A. MS Clinical Trials
`17. Here I briefly describe human clinical trial protocols generally, and then
`
`the specific problems with MS clinical trials.
`
`i. Human Drug Clinical Trials
`18. Human clinical trials for proposed medications usually follow a
`
`standard series of “Phases.” Drug development begins with pre-clinical work in
`
`animals. If that work shows promise, drugs are introduced into humans for the first
`
`time in “Phase I” trials. These trials typically introduce one or more low doses of
`
`the compound into a small number of healthy or otherwise relatively stable human
`
`volunteers to evaluate the compound’s safety and to collect pharmacological data.
`6
`
`
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`19. Sometimes, Phase I trials are divided into Phase Ia and Ib. Phase Ia
`
`trials can involve single doses given to subjects. The physician monitors for adverse
`
`events, and will often also collect biological samples so that pharmacologists can
`
`develop pharmacokinetic (PK) and pharamcodynamic (PD) models of the drug’s
`
`behavior in humans. PK measures how the body processes a compound, whereas
`
`PD measures how the drug affects one or more aspects of the subject’s physiology.
`
`If the drug is deemed safe enough after Phase Ia, some clinical trial programs will
`
`use a Phase Ib trial to evaluate the effects of regular dosing over a period of time.
`
`20. Next, Phase II trials will test a drug’s safety and efficacy in a larger
`
`population of people afflicted with the target condition, often 100-200 patients.
`
`Phase II studies will often focus on identifying a candidate dose for the Phase III
`
`trial. For that reason, it is common in Phase II trials to include doses expected to
`
`have a range of safety and efficacy effects. These are proof of principle studies. The
`
`candidate doses are usually compared to placebo or other comparator during an
`
`administration period of several months.
`
`21. This process allows the sponsor to develop information about the
`
`balance among dose, efficacy, and safety. This information provides important tools
`
`for regulators and physicians. It allows regulators to make decisions about the
`
`optimal average dose for a given population, and physicians to make decisions about
`
`how to vary doses for individual patients in the event the drug is ultimately approved.
`
`
`
`7
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`If the Phase II trial identifies one or more doses with promising results,
`
`22.
`
`the sponsor usually will select the dose(s) with the optimal efficacy-safety mix to
`
`include in a Phase III trial. These are large studies with potentially 1,000 or more
`
`patients suffering from the targeted condition. The candidate dose(s) is compared
`
`to placebo or other comparator drugs, usually in a “double-blind” fashion in which
`
`neither the patients nor the administering physicians know if the patient is getting
`
`the candidate drug or its comparator. Blinding is critical to limit the risk of placebo
`
`effects, in which the physicians’ or patients’ expectations or hopes about the drug’s
`
`performance color the trial’s results.
`
`ii. The Challenges of MS Trials
`23. Clinical trials for MS patients differ somewhat from the usual pattern
`
`due to the nature of the disease and its available therapies.
`
`24. MS is a disease in which the immune system attacks the central nervous
`
`system. The cause is unknown. The disease strikes women more than men in their
`
`20s to 40s, and will progress over the course of decades. There is no cure for MS
`
`and the patients will have the disease for the rest of their lives. As of June 2006, MS
`
`was typically categorized into four disease courses, of which relapsing-remitting
`
`multiple sclerosis (RRMS) was the most common.
`
`25. As I describe in my first declaration (Ex. 2003 ¶¶ 46-47), RRMS
`
`manifests as episodes or “relapses” in which the patient experiences a period of
`
`
`
`8
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`inflammation and accompanying symptoms, followed by a period of “remission.”
`
`As the disease progresses, patients may accumulate symptoms that persist during the
`
`remission phase, and eventually may transition into a phase in which symptoms
`
`begin to accumulate continuously. Patients experience the disease and its effects in
`
`widely disparate ways. The type of symptoms, the time between relapses, relapse
`
`duration, relapse severity, and the extent of residual effects all vary considerably
`
`from patient to patient.
`
`26. These features of the disease along with developments in therapeutic
`
`approaches have presented several challenges to MS clinical trial design.
`
`27. First, the high level of inter-patient variation makes it difficult to
`
`evaluate new drug therapies. To identify a positive therapeutic signal, an RRMS
`
`clinical trial typically must have a large testing population and long duration, often
`
`about two years. Only in those circumstances can a trial produce a statistically
`
`reliable measure of efficacy.
`
`28. Second, the need for long-duration studies poses its own problem.
`
`Patients in placebo-controlled trials would be at risk of going without treatment for
`
`two years if they receive the placebo in the trial. During that time, the disease could
`
`progress, and their condition could worsen. In the 1980s, when no medications
`
`existed that could modify the course of the disease, this was not a problem. Patients
`
`on placebo were no worse off than they would have been without treatment. But
`
`
`
`9
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`beginning in the 1990s, such medications began to establish a track record of
`
`successfully helping affect the course of the disease.
`
`29. That presented dilemmas for MS trial designers. Placebo-controlled
`
`trials are the gold-standard when evaluating new drugs. It is possible to design trials
`
`that use approved medicines as comparators, but these trials are less likely to produce
`
`data useful in evaluating the tested compound. At the very least, such trials would
`
`require more patients and/or a longer duration to produce enough data to do so.
`
`30. Third, RRMS’s inter-patient variability also complicates how to
`
`measure a compound’s effectiveness. There are no definitive MS biomarkers. So
`
`far, the most useful are MRI scans of a patient’s CNS, which look for characteristic
`
`lesions to assess disease activity and progression. In addition to that technique,
`
`physicians have adopted various scoring systems to measure disease progression
`
`based on a patient’s symptoms and signs. These measures suffer from at least some
`
`degree of subjectivity on the part of both the patient and the physician, a difficulty
`
`compounded by MS patients’ susceptibility to placebo effects and the high inter-
`
`patient variability in how the disease manifests. A patient’s belief that a treatment
`
`is working can make clinical scoring difficult.
`
`31. All of these complications make MS clinical trials inherently
`
`complicated and more difficult to predict than those involving many other
`
`conditions.

`B.
`The Phase I Fingolimod Transplant Trials
`32. Fingolimod’s Phase I trials were conducted in stable kidney transplant
`
`patients to test safety and collect PK/PD data. Physicians first introduced fingolimod
`
`into humans in a Phase Ia single-dose study described in the Budde reference (Ex.
`
`1008). Thereafter, physicians conducted a Phase Ib multi-dose study over 28 days
`
`as reported in the Kahan 2003 reference (Exhibit 1031). In addition, another study
`
`detailed PK/PD data for daily doses over a 12 week period, as reported in the Park
`
`abstract and paper at Exhibits 2048 and 1019.
`
`33. Neither Budde nor Kahan 2003 measured clinical efficacy, i.e., the
`
`drug’s ability to prevent organ transplant rejection. By design, the Phase I trials did
`
`not allow for that analysis. The tested patients were already stable. No change in
`
`their medical condition was measured. Fingolimod was introduced only over a short
`
`period into stable patients. Instead, each study assessed fingolimod’s safety, and
`
`further collected PK and PD data for a variety of doses, including 0.5 mg daily.
`
`34. PD analysis focused on what was believed to be fingolimod’s primary
`
`mechanism of action, the sequestration of lymphocyte white blood cells in lymphatic
`
`tissue outside the blood stream. That process was believed to inhibit the immune
`
`system mechanisms responsible for organ transplant rejection and at least some
`
`autoimmune diseases. The Phase Ia Budde study was only single-dose and in any
`
`event too small to detect the relationship, but the daily-dose studies in Kahan 2003
`
`
`
`11
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`and the Park papers showed that fingolimod’s effect on lymphocyte sequestration
`
`was dose-dependent. (Kahan 2003, Ex. 1031 at 1081; Park 2003, Ex. 2048 at 333;
`
`Park 2005, Ex. 1019 at 683.) That is, higher doses suppressed circulating
`
`lymphocytes to a greater degree than lower doses.
`
`C. The Phase II MS Trial
`35. Novartis proceeded into Phase II trials for RRMS based on the Phase I
`
`transplant studies. I was on the MS Phase II trial DSMB. The Kappos 2005 abstract
`
`(Ex. 1007) reports the trial’s design and results.
`
`36. The study involved testing doses of 5.0 and 1.25 mg daily in 281
`
`patients with RRMS over six months compared to placebo. (Ex. 1007 at II/41.)
`
`Patients had monthly MRI brain scans and two neurological assessments at the 3-
`
`month and 6-month points. (Id.) Using these benchmarks, the study showed that
`
`both doses resulted in fewer brain lesions in MRI scans, with the 5.0 mg dose
`
`producing somewhat fewer average lesions than the 1.25 mg dose. (Id.) Similar
`
`effects were found when measuring the volume of existing lesions. (Id.) Likewise,
`
`fingolimod reduced relapses below placebo levels, and to an equal extent for both
`
`doses. (Id.) The study authors concluded that “[t]here was no compelling dose-
`
`related difference in efficacy on MRI or clinical endpoints” between the doses.” (Id.)
`
`In addition, “[t]reatment was generally well tolerated[.]” (Id.) However, “[a]dverse
`
`
`
`12
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`events were more common in the 5 mg group,” though the authors characterized
`
`these as “mild.” (Id.)
`
`37.
`
`I was surprised that the 5.0 mg and 1.25 mg daily produced essentially
`
`the same efficacy results. Based on (i) pre-clinical and the Phase I PK/PD data; (ii)
`
`the results in the transplant context; and (iii) the belief that the mechanism of action
`
`for suppressing transplant rejection and helping RRMS were the same, I expected
`
`the higher 5.0 mg daily dose to be more effective than the 1.25 mg daily dose.
`
`38. The pre-clinical and Phase I data had shown that higher doses
`
`suppressed lymphocytes to a greater extent than lower doses, and that greater
`
`suppression yielded better clinical results. The transplant studies had shown that
`
`doses of 1.0 mg daily were not effective, but that doses of 2.5 mg daily and 5.0 mg
`
`daily were effective. I therefore expected the 5.0 mg daily dose to be more effective
`
`than 1.25 mg daily.
`
`39.
`
`I later learned that FDA was dissatisfied with the Phase II trial’s failure
`
`to identify a minimum effective dose. FDA accordingly pushed Novartis to include
`
`a lower dose in the Phase III trial. FDA had taken similar steps in other MS drug
`
`trials. In the 1990s, FDA had pushed a sponsor to test a lower dose of interferon-
`
`beta that those in the field did not expect to work. (IFNB Study, Ex. 2073.) I was
`
`involved in that trial.
`
`
`
`13
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`40. Because MS disease-modifying therapies are designed to be used for
`
`an extended period—possibly for the patient’s entire lifetime—FDA wants to
`
`understand the drug’s safety-efficacy profile. A clinical trial will test the drug’s
`
`safety over two years, but for some medications safety problems will not become
`
`apparent until later. It is important for FDA to understand the drug’s profile to be
`
`able to provide guidance if such problems later develop.
`
`41.
`
`In 2005, FDA was confronted with exactly this situation. An approved
`
`drug called “Tysabri” had developed serious safety issues with prolonged use. Some
`
`patients developed a serious, potentially fatal brain infection. FDA temporarily had
`
`to suspend Tysabri’s approval. This experience had made FDA and the community
`
`of MS physicians especially sensitive to identifying safe doses for MS medications.
`
`42.
`
`In addition, safety-efficacy information can help physicians adjust
`
`doses for individual patients. If a patient suffers an unusual reaction to the drug, this
`
`data can allow the physician to explore using lower doses if warranted to try to solve
`
`the problem. For a drug that affects two of the most complex systems in the human
`
`body—the immune and nervous systems—the ability to adjust dosing to fit
`
`individual patients can be valuable.
`
`D. The Phase III Trials
`43. Against this backdrop, I participated in an advisory board of physicians
`
`that helped Novartis to design the Phase III trials. I attended an advisory board
`
`
`
`14
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`meeting in Vienna in June 2005 that included many of the physicians involved in the
`
`clinical trials, including Dr. Kappos (the author of Kappos 2005). I additionally
`
`ended up taking a senior role in the paper publishing the results of one of those trials,
`
`as I discuss further below.
`
`i. Trial Designs
`44. While I do not recall the details of the meeting in Vienna, I do recall
`
`being involved in discussions with Novartis personnel and other advisory board
`
`members about different dose tracks for the Phase III trials. Our focus was on
`
`confirming the 1.25 mg daily dose as the effective dose. We debated whether and
`
`how to include the lower dose FDA wanted. As I describe above (¶ 27), there are
`
`serious risks involved in including a potentially ineffective dose in a Phase III
`
`clinical trial. Patients taking that dose run the risk that their disease will progress,
`
`unchecked, for two years. That risk is inherent in a Phase III trial with a placebo,
`
`but including a potentially ineffective dose in the trial could double the number of
`
`patients exposed to that risk.
`
`45. Novartis ultimately adopted a novel trial design to mitigate this risk.
`
`Novartis conducted three Phase III trials: FREEDOMS I, FREEDOMS II, and
`
`TRANSFORMS. The two FREEDOMS trials evaluated 1.25 mg and 0.5 mg daily
`
`against placebo. Due to FDA-related delays, FREEDOMS I began to recruit patients
`
`first, in 2006. FREEDOMS II started later. TRANSFORMS evaluated the same
`
`
`
`15

`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`doses as the FREEDOMS trials, comparing their performance not to placebo but
`
`rather to another approved MS medication, Avonex (interferon).

`
`
`
`
`48. Consistent with Novartis’s focus on the 1.25 mg dose, Novartis publicly
`
`described its Phase III trial program as designed to “confirm” the Phase II results.
`
`Novartis’s press release describing the trial quoted Dr. Paul O’Connor, MD, of St.
`
`Michael’s Institute, in Toronto, Canada, as stating that “’[w]e hope that the
`
`magnitude of benefits shown in the Phase II study can be confirmed in the larger
`
`scale Phase III study program, which is currently being initiated.’” (Novartis Press
`
`Release, Ex. 2072 at 1; Chavez, Ex. 2031 at 1.) The press release also quoted Dr.
`
`Kappos describing “’the Phase III clinical program’” as seeking to “’confirm[] the
`
`promise of the Phase II results[.]’” (Novartis Press Release, Ex. 2072 at 2; Chavez,
`
`Ex. 2031 at 2.) These statements were all referring to the 1.25 mg dose used in the
`
`Phase II trial. At that time, there was no experience at all with a 0.5 mg dose because
`
`that dose had not yet been administered to any MS patient.
`
`49. Others in the field repeated this description and likewise described the
`
`Phase III trial as seeking to “confirm” the “exciting” Phase II results. (Budde 2006,
`
`Ex. 2030 at 22.) The lower dose was included just “to be evaluated.” (Doggrell
`
`2007, at 385.)

`
`ii. Doctors’ Skepticism
`50. Perhaps because Novartis’s focus was so clearly on the 1.25 mg dose,
`
`at least some doctors expressed open skepticism about including the 0.5 mg dose
`
`arm in the Phase III trials at all.
`
`51.
`
`In the Spring of 2007, Novartis asked the hospital where I work, Mount
`
`Sinai in New York, to participate in the TRANSFORMS trial. Mount Sinai, like
`
`other hospitals, has a panel to review clinical trial requests called an “Institutional
`
`Review Board,” or “IRB.” Mount Sinai’s IRB is made up of physicians, researchers,
`
`nurse practitioners, and others. They will review clinical trial requests and can
`
`conduct their own research analysis to decide whether to participate in a clinical trial.

`iii. Trial Results
`In 2010, Dr. Kappos and others published their findings from the
`
`59.
`
`FREEDOMS I trial in the New England Journal of Medicine, the Kappos 2010
`
`reference (Ex. 1038).
`
`60. Contrary to expectations, the FREEDOMS I results did far more than
`
`“confirm” the Phase II study. It dramatically extended those results. Kappos 2010
`
`
`
`21
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`showed that the 1.25 mg and 0.5 mg doses were equally effective. (Ex. 1038 at 390.)
`
`Both doses equally reduced relapses, inhibited lesion formation, and slowed
`
`disability progression. (Id. at 390-94.) I was surprised by the results.
`
`61. At the time, I was involved in the FREEDOMS II trial, and also was
`
`an investigator on another trial called INFORMS that tested fingolimod in a different
`
`form of MS called “Primary Progressive” MS, or “PPMS.” INFORMS was a large
`
`Phase III trial involving 970 patients observed over 3-5 years starting in September
`
`2008. We were so skeptical that 0.5 mg daily would not be effective that we did not
`
`even include that dose in the INFORMS PPMS trial at all.
`
`62. Some of this surprise can be seen in the Cohen paper on the
`
`TRANSFORMS trial. (Ex. 2035.) That paper reported that “[t]he selection of the
`
`dose of fingolimod was based on [PK] and [PD] considerations from earlier studies,
`
`which suggested that a dose of 1.25 mg would be fully effective.” (Id. at 411.) The
`
`“lower dose of 0.5 mg … was expected to have a submaximal effect on lymphocyte
`
`recirculation,” and thus submaximal (if any) efficacy. (Id.) Contrary to
`
`expectations, however, the 0.5 mg daily dose was “at least as effective” as 1.25 mg
`
`daily. (Id.)
`
`63.
`
`I was senior author on the final Phase III trial paper for FREEDOMS
`
`II. We likewise found that the two doses were equally effective, to the extent our
`
`data covered both doses. (Calabresi 2014, Ex. 2042 at 545,) (When the
`
`
`
`22
`
`
`
`IPR2017-00854
`U.S. Patent No. 9,187,405
`FREEDOMS I results became available, we had discontinued the 1.25 mg daily dose
`
`and switched all patients to the 0.5 mg daily dose.)
`
`E.
`Subsequent Dosing Research
`64. The Phase III results left Novartis and FDA in the much same position
`
`as the Phase II results—without enough data to identify the minimally effective dose.
`
`FDA accordingly made it a condition of approval for the 0.5 mg daily dose that
`
`Novartis would conduct a Phase IV study 0.25 mg daily. (FDA Approval Letter,
`
`Ex. 2037 at 7.) In addition, physicians published studies of lower dosing regimens
`
`utilizing less-than-daily dosing, such as every-other-day dosing. (Tanaka 2013, Ex.
`
`2067; Yamout 2015, Ex. 2068; Zecca 2017, Ex. 2069.)
`
`65. The results of the Phase IV study are not yet available. Of course, if
`
`the 0.5 mg dose results had been expected in June 2006, then FDA would have
`
`pushed Novartis to experiment with an even lower dose earlier in the Phase III trials
`
`to identify the lowest dose showing any efficacy.
