Bottom line is expectations are very low on Tysabri and we see a 30–35% probability of success (vs. buyside consensus 20–25% or lower), which would lead to up to $1–2B revenue upside and $4 or more of EPS accretion (royalty is also paid out to PRGO). Thus, $4 accretion x 20 P/E multiple implies up to $80 or 20% upside to the stock value over time, which isn't unreasonable given a new growth driver for this pipeline stock. We see some modest 15%+ chance of a "mixed" result, e.g., a big subset of "responders" gets great benefit and BIIB might still try to file with FDA given the unmet medical need. We see 50% probability there's not enough signal to file but minimal downside given it's not in Street estimates because it's viewed as a high-risk study. Bottom line is we like BIIB also for upcoming Alzheimer's data in July as well as more pipeline catalysts coming including LINGO in early 2016. We do see this as a call option but reasons it could work include: 1) unique composite endpoint designed with experience from prior SPMS studies and objective timed 25F walk test; 2) registry data and Phase II data show improvement in ambulation and walking speeds; 3) dramatic reduction in key CSF inflammation markers (e.g., cytokine CXCL13 – see literature and data inside); 4) 10%+ off-label use and some KOLs think it does work for some pts and there are "responders" who could drive benefit for the whole group. See inside for much more details. Separately, Phase II Tysabri stroke coming soon – interesting opportunity: 1) mechanism and science make sense whereby blocking T-cells into brain could protect against stroke damage; 2) Gilenya works similarly and reduced brain damage in preclinical models (but has acute CV side effects in MS, so can't be developed here); 3) Tysabri might have longer window to work than current drugs and Phase II is testing within nine hours of onset. Stroke has been a graveyard for development, with many failures, so this is only a call option. If treating only 100k of the 1–2M strokes per year WW, this could be a $500M+ to $1B opportunity ($20– 30/share upside). Priced as of prior trading day's market close, EST (unless otherwise noted).

    Source: Bloomberg and RBC Capital Markets estimates for Upside/Downside/Target

    Target price/base caseOur $525 price target is based on a 27x P/E our 2016E EPS.This is also possible based on DCF analysis that values the basebusiness ($314/share) including Tecfidera and hemophiliaprograms. For various pipeline programs, we add probabilityadjusted value of ~$211/sh total for Tysabri SPMS, ANTI-LINGO, BIIB037 (5060% POS), $SMNRx, IPF, and ANTI-TWEAK.

    Upside scenarioOur upside scenario of $565 is based on similar assumptions asour base case for the core business (Avonex, Rituxan, Tysabri),Tecfidera and the new hemophilia franchise (Eloctate,Alprolix). We assign greater probability adjusted value for thepipeline (515% higher for each of the six opportunities) aswe gain visibility on their prospects in next 12 months. Keydrivers in 2015 would be data readouts from Anti-LINGO andTysabri SPMS, which if both are positive may drive shareshigher toward our upside scenario and increase probability ofsuccess.

    Downside scenarioOur downside scenario of $314 is based on DCF analysison only the existing core business (Avonex, Rituxan, Tysabri)plus the contribution from Tecfidera and recently launchedhemophilia franchise (Eloctate, Alprolix). We do not includeany pipeline opportunities as data is limited and many arehigh-risk. This is also possible based on a 16x P/E on our 2016EEPS, at the lower end of the peer group comparables.

    Investment summaryWith $10B+ of pipeline data reading out in the next 12months or more, we would own BIIB for favorable risk/reward.Tysabri SPMS $2B opportunity isn't in consensus, and if itworks, it could be $4+ accretive to earnings, in our view. Thesecond opportunity is BIIB037 (robust Phase Ib Alzheimersdata recently presented at ADPD). This is relatively early-stage,with Phase III to begin in 2015 and more data from the ongoing6mg/kg group coming in H2:15. Furthermore, anti-LINGO MSdata are due in mid-2016. Long-term, we are keenly trackingthe continued uptake of Tecfidera, which may slow down asit enters its third year of launch, and generic Copaxone couldenter the MS market in 2015. However, we do believe thepositive pipeline events will likely outweigh any slowdown inits core MS business.

    Potential catalysts for the stockSeries of positive pipeline data: Several of BIIBs key late-stageblockbuster pipeline drugs are expected to read out in thenext 1218 months, beginning with: 1) Tysabri SPMS in theH2:15; 2) BIIB037 Phase III initiation and more data from 6mg/kg dosing in H2:15; and 3) Anti-LINGO in MS in mid-'16. Risk/reward currently favors the upside, in our view, and if any ofthese data are positive, the stock could move 10% or more.

    Risks to our investment thesisDisappointing Tecfidera sales: Outperformance in the stock inthe last two years has largely been driven by the impressivelaunch and uptake of its oral MS drug, Tecfidera. In Q3:14,it missed consensus estimates for the first time and alsoreported its first case of a PML-related death. If it continues tomiss estimates or new safety signals emerge, this could weighdown the stock.

    IP litigation overhang: Tecfidera is protected until 2028 onits dosing patents, but given that several different companies(FWP, XNPT, ALKS) are working on different formulations ofthe active ingredient DMF, BIIB could get pulled into lengthypatent litigations with any of these companies, which maycreate an overhang on the stock as Tecfidera is a significantcontributor to BIIBs top and bottom lines.

  • Tysabri for SPMS (Phase III ASCEND readout: early 2H:15)

    Background: Tysabri is approved as monotherapy in Crohns disease, as well as in RRMS, with heralded best efficacy (% ARR of 67%) in reduction of risk of relapse with clinical signs of slowing of disability accumulation. Tysabri binds to the alpha 4 integrin of adhesion molecules found on lymphocytes, which prevents its interaction with endothelial cells. Tysabris overall effect is driven by preventing migration of auto-reactive leukocytes into target organs, which then exacerbates inflammation.

    SPMS (along with PPMS, which is more rare) make up to 40% of MS patients for whom there are limited treatment options. Patients experience continual axonal damage (neurofilament light chain in CSF) and demyelination (myelin basic protein) along with widespread, systemic inflammation (osteopontin, CXCL13 and MMP9 in CSF).

    This Phase III study (n=856) examines Tysabris ability (vs. placebo, both IV Q4W of 300mg or currently marketed dose in RRMS) to slow relapse-independent disability progression in patients with secondary progressive MS over 96 weeks (24 months). The primary endpoint is a composite of EDSS, T25FW, and 9-Hole Peg Test.

    Exhibit 2: Study overview of Tysabri in patients with SPMS (ASCEND study)

    Study Design Phase III, multicenter, international, randomized, double-blind, placebo-

    Primary Endpoint The proportion of subjects experiencing confirmed progression of

    disability as measured by a composite endpoint (Expanded Disability

    (9HPT)

    Key Inclusion Criteria SPMS 2 years with EDSS 3.0 to 6.5 (inclusive)

    Key Exclusion Criteria RRMS & PPMS

    Est. Primary Completion Date June 2015

    Source: Company reports, RBC Capital Markets estimates, clinicaltrials.gov

    Four key reasons that Tysabri could work in SPMS:

    1. In an open-label Phase IIa (n = 17) 60-week study, decrease in CSF markers of inflammation, axonal damage, and demyelination (osteopontin, neurofilament, myeline basic protein) was observed alongside reduction in MRI atrophy endpoints at wk 12 from baseline. An improvement in EDSS (lowering of score) was also observed (p = 0.01) at wk 60 vs. baseline. These signs of efficacy in reduction of inflammation and tissue damage suggest that Tysabri might reduce intra-thecal inflammation and axonal damage in progressive forms of MS, although we note the very small number of patients in trial.

    2. In a retrospective analysis of two Phase I and II clinical trials of Tysabri in SPMS patients, an improvement in walking was observed as assessed by the timed 25-foot walk (T25FW) test. Even though this ad-hoc analysis is limited by the small sample size and short duration of therapy, if these observations play out in the Phase III study, it would increase the chance of hitting the primary endpoint as it is a composite endpoint that includes the T25FW test.

    3. KOLs indicate that Tysabri is used widely off-label for SPMS already. Based on our discussion with various KOLs, up to 15% of Tysabri use is for SPMS patients, as this is the best option they have so far. In order to get around the reimbursement hurdle, docs mentioned that these patients are diagnosed as RRMS so that reimbursement can be approved. In terms of the Phase III ASCEND study, physicians generally agreed that there is good chance for it to hit on the T25W endpoint.

    4. Mild EDSS entry criteria may also increase chance of Tysabri showing a benefit. One of the key inclusion criteria for the ASCEND study is the EDSS score of 3.0 to 6.5. Baseline data indicate that approximately one-third of enrolled patients have EDSS score between 3.0 and 5.5. These patients are generally milder SPMS patients who do not require assistance for walking. KOLs believed that these milder patients are more likely to have inflammatory lesions, which is the mechanism that Tysabri targets. Thus, we believe Tysabri is more likely to benefit these milder patients and potentially show a meaningful difference in the T25FW or EDSS endpoint.

  • Tysabri for acute ischemic stroke (Phase II ACTION readout: mid-2015)

    In ischemic strokes, blockage in blood vessels to the brain may lead to cerebral infarctions and cause local death of the tissue. This in turn would lead to loss of neurologic function. T lymphocytes play an important role in acute ischemic strokes because these T cells are important to the evolution of brain infarctions and the accompanying neurological deficit. It is thought that T lymphocytes start to migrate and accumulate in the ischemic brain during the first five days and thus trigger tissue damage through secretion of proinflammatory cytokines.

    Exhibit 4: T lymphocytes infiltrate and accumulate in the ischemic brain during the first five days (mouse model)

    Source: Shichita et al., Nature Medicine 2009

    The ability of T lymphocytes to migrate across the blood-brain barrier and infiltrate the brain is dependent on the interplay between very late antigen-4 (VLA-4) and vascular cell adhesion molecule-1 (VCAM-1) on endothelial cells. Therefore, agents that modify VLA-4 function may have an effect in treating acute ischemic stroke. Tysabri (natalizumab), a humanized monoclonal antibody used in treating multiple sclerosis and Crohnss disease, can block VLA-4, and thus it may also be effective at treating acute ischemic stroke. However, there are contradictory animal studies on the effectiveness of treating stroke through inhibiting T cell migration across the blood-brain barrier.

  • Supporting evidence from animal model

    In a mouse study of Gilenya, which inhibits T cell migration into inflammatory tissues, positive results were seen (Nature Medicine, August 2009). Mice intravenously treated with Gilenya showed significantly reduced infarct volume and reduced number of infiltrating T lymphocytes after focal brain ischemia was induced. This supports the hypothesis that immunomodulatory agents may treat ischemic brain injury by preventing the infiltration of T lymphocytes and thus may even extend the therapeutic time window for neuroprotection.

  • Controversial evidence from animal models However, there is also controversial data from animal studies that do not support the use of T cell-migration-inhibitory agents in treating acute ischemic stroke. In a recent paper (Stroke, June 2014), animals treated with a monoclonal anti-CD49d antibody that blocks 4-integrin (Tysabri blocks 4 integrin and does not have Gilenyas acute CV side effects in MS) had reduced T cell invasions (fewer CD3+ T lymphocytes) by day 5. However, that did not correspond to a positive effect on stroke outcome. Therefore, more studies are needed in order to determine if certain immunomodulatory agents such as Tysabri may treat acute ischemic stroke through preventing T lymphocyte migration.

  • ValuationOur $525 price target is based on a 26.6x P/E our 2016E EPS. This is also possible based onDCF analysis that values the base business ($314/share) including Tecfidera and hemophiliaprograms. For various pipeline programs, we add probability adjusted value of $211/sh totalfor Tysabri SPMS, ANTI-LINGO, BIIB037 (5060% POS), $SMNrx, IPF, and ANTI-TWEAK.

    Price target impedimentsRisks to our thesis are disappointing Tecfidera growth and sales, worse than expected erosionof Avonex/Plegridy franchise, and less than projected growth in Tysabri. However, we thinkthat competition, market share loss, and new oral MS drugs are well known already by theStreet and reflected in estimates. Failure of BIIB's pipeline programs (ANTI-LINGO for re-myelination, Tysabri for SPMS, as well as autoimmune and fibrotic diseases) to have successfuldata readouts in the next 13 years would also contribute to downside, given that BIIB'spremium valuation to peers reflects some expectation of success in continued generations ofblockbuster therapies.

    Explanation of RBC Capital Markets Equity rating systemAn analyst's 'sector' is the universe of companies for which the analyst provides research coverage. Accordingly, the rating assignedto a particular stock represents solely the analyst's view of how that stock will perform over the next 12 months relative tothe analyst's sector average. Although RBC Capital Markets' ratings of Top Pick (TP)/Outperform (O), Sector Perform (SP), andUnderperform (U) most closely correspond to Buy, Hold/Neutral and Sell, respectively, the meanings are not the same becauseour ratings are determined on a relative basis.RatingsTop Pick (TP): Represents analyst's best idea in the sector; expected to provide significant absolute total return over 12 monthswith a favorable risk-reward ratio.Outperform (O): Expected to materially outperform sector average over 12 months.Sector Perform (SP): Returns expected to be in line with sector average over 12 months.Underperform (U): Returns expected to be materially below sector average over 12 months.Risk RatingAs of March 31, 2013, RBC Capital Markets suspends its Average and Above Average risk ratings. The Speculative risk rating reflectsa security's lower level of financial or operating predictability, illiquid share trading volumes, high balance sheet leverage, or limitedoperating history that result in a higher expectation of financial and/or stock price volatility.

    Distribution of ratingsFor the purpose of ratings distributions, regulatory rules require member firms to assign ratings to one of three rating categories- Buy, Hold/Neutral, or Sell - regardless of a firm's own rating categories. Although RBC Capital Markets' ratings of Top Pick(TP)/Outperform (O), Sector Perform (SP), and Underperform (U) most closely correspond to Buy, Hold/Neutral and Sell, respectively,the meanings are not the same because our ratings are determined on a relative basis (as described below).
