`determining alternate explanations for
`findings and results.
`
`1. Disclose the principal sources of fund-
`ing in a manner that permits easy recogni-
`tion by the reader.
`
`2. Disclose the existence of all potential
`conflicts of interest among supplement
`contributors, including financial or per-
`sonal bias.
`
`3. Describe all drugs by generic name
`unless the use of the brand name is neces-
`sary to reduce the opportunity for confu-
`sion among readers.
`
`4. Strive to report subjects of current inter-
`est to managed care pharmacists and other
`managed care professionals.

`
`T he development of injectable biologic agents has revolution-
`
`ized the treatment of numerous diseases, including multiple
`sclerosis (MS) and psoriasis. These agents have the potential
`for long-term benefits, including reduced disease activity, improved
`quality of life, and decreased utilization of total health care services.
`As newly approved biologics for the treatment of MS and psoriasis
`become available, managed care decision makers must determine the
`appropriate use of these agents based on long-term efficacy, safety, and
`cost. The goal of this supplement is to provide information from clin-
`ical trials and from the experience of renowned specialists to aid in
`this endeavor.
`Multiple sclerosis is a chronic, multifocal, demyelinating disease
`of the central nervous system (CNS). The onset of MS typically occurs
`in early adulthood,1 and MS is the leading cause of nontraumatic CNS
`morbidity in young and middle-aged adults.2 In the United States, the
`annual per-patient cost of MS has been estimated at $34,000, with a
`total lifetime per-patient cost of $2.2 million; a conservative estimate
`of the national annual cost is $6.8 billion.3 MS is a complex and het-
`erogeneous disease, with high intrapatient and interpatient variability
`in its clinical course and manifestations. Consequently, physicians
`who treat patients with MS must tailor treatment to individual
`patients and actively plan for the long-term management of the
`disease.
`Four articles in this supplement focus on the role of biologics in
`the management of MS. The first article, by James R. Miller, MD, pro-
`vides an overview of the 4 biologic agents that are available in the
`United States for the treatment of relapsing-remitting MS as well as
`the complexities involved in the diagnosis and clinical course of MS.
`Data supporting early treatment of patients at high risk for MS also are
`discussed. The second article, by Howard S. Rossman, DO, FACN,
`reviews data on the development of neutralizing antibodies (NAbs) to
`biologic agents used to treat MS. Studies show that differences exist
`among biologics regarding the risk of developing NAbs and that these
`NAbs reduce or abolish the therapeutic effects of biologics. The
`article also discusses the implications of NAbs for neurologists and
`managed care professionals.
`The third article, by William H. Stuart, MD, presents an MS treat-
`ment algorithm recently developed by a panel of neurologists who are
`MS experts. This algorithm provides best-practice guidelines on choos-
`ing the appropriate biologic agent for initiating therapy, managing
`occasional relapses, and selecting agents that can be added to
`biologics in patients whose disease progresses while they are on
`treatment. The fourth article, by my colleagues and me, provides a
`model treatment algorithm for use in the managed care setting, which
`was developed by a group of managed care professionals. This model

`
`MS algorithm provides health care professionals with guidelines on the
`following disease management issues: when to initiate treatment, how
`to select a biologic agent as the initial therapy, the use of magnetic
`resonance imaging in the diagnosis and management of patients with
`MS, when to test for NAbs and how to manage patients who have
`positive test results for NAbs, and how to manage patients who
`experience progression during treatment. An algorithm for NAb
`testing also has been proposed that, while recognizing the authority of
`the physician to make ultimate prescribing decisions, can be
`incorporated into a patient’s care path to ensure the quality of care
`without placing a burden on the patient.
`An estimated 4.5 million adults in the United States have psoria-
`sis, and approximately one third (1.5 million) of these individuals
`have moderate-to-severe disease.4 The financial burden of psoriasis is
`substantial, with annual U.S. economic costs estimated at $4.3 bil-
`lion.5 Patients with moderate-to-severe psoriasis typically require
`chronic treatment with systemic therapy or phototherapy. Although
`conventional systemic agents can be effective in producing short-term
`reductions in disease severity, the long-term, chronic use of these treat-
`ments is limited by safety and tolerability concerns. Novel injectable
`biologics, which have been developed based on an understanding of
`the role of T cells in the pathogenesis of psoriasis, have advanced the
`treatment of moderate-to-severe psoriasis.
`Alefacept was the first biologic therapy approved for the treatment
`of moderate-to-severe chronic plaque psoriasis in the United States,
`and it has been available here for more than 1 year. Two articles in this
`supplement review the use of alefacept in the treatment of psoriasis.
`The article by Jay N. Gade, MD, PhD, provides an update on the clin-
`ical efficacy and safety of alefacept in patients with psoriasis. Alefacept
`has proven to be an effective intermittent therapy for psoriasis that
`offers patients extended treatment-free and disease-free periods. As a
`result of prolonged remissions, overall drug utilization may be reduced.
`In the second article, I review key considerations for the long-
`term assessment of biologic therapies in psoriasis. These
`considerations establish the importance of efficacy, safety, and cost
`parameters measured over a longer course of therapy than the
`traditional 3-month or 6-month time period utilized to date.
`It is hoped that the timeliness and clinical relevance of the infor-
`mation provided in this Journal supplement will assist you in improv-
`ing the care of your patients with MS or psoriasis and will ensure the
`use of biologic therapies in the most cost-efficient manner.

`
`ABSTRACT
`
`OBJECTIVE: To introduce a model treatment algorithm for use in the managed
`care setting as a strategy to provide ongoing disease management and long-term
`care for patients with multiple sclerosis (MS), with the goal of delaying disease
`progression and the associated disability and cognitive dysfunction.
`
`SUMMARY: MS is a chronic inflammatory disorder of the central nervous system
`that is associated with progressive disability and cognitive dysfunction. Currently,
`management of MS involves planning an effective long-term treatment strategy
`that can delay the progression of the disease. This article reviews a typical
`stepped-care approach to treating MS that is based on the concept of a platform
`drug, which is an agent that provides baseline immunomodulatory action
`throughout the course of the disease.
`Considerations for selecting a platform therapy include the effect on the full
`spectrum of MS (disability, relapses, lesion load, and atrophy as well as patient
`compliance and the potential impact of neutralizing antibodies [NAbs]). Currently,
`4 first-line therapies are approved for relapsing MS: the 3 interferon beta (IFNβ)
`products and glatiramer acetate. Of these, the IFNβs are generally recommended
`as platform therapy because all have shown significant effects on relapses, mag-
`netic resonance imaging parameters of the disease, and because intramuscular
`(IM) IFNβ-1a (Avonex) and subcutaneous (SC) IFNβ-1a (Rebif) have been shown
`to slow the progression of sustained disability.
`Patients being treated with IFNβs can develop NAbs to the drug, which can
`lead to a loss of efficacy and subsequent occurrence of breakthrough disease.
`The 3 different formulations of IFNβ are associated with a varying incidence of
`NAbs (IM IFNβ-1a, 5%; SC IFNβ-1a, 24%; IFNβ-1b [Betaseron], 45%). Antibodies
`also form against glatiramer acetate, although their clinical significance needs
`to be elucidated. As the disease progresses or has periods of aggressive activity,
`the stepped-care approach is to add other agents onto the platform therapy to
`improve control of the disease.
`
`CONCLUSION: Stepped care, as outlined in this model treatment algorithm for the
`managed care setting, is an effective method to achieve the fundamental goal of
`MS treatment, that is, to delay disease progression and the associated disability
`and cognitive impairment.

`
`Multiple sclerosis (MS) is a chronic demyelinating disease
`
`of the central nervous system. Natural history data sug-
`gest that in a majority of patients diagnosed with clini-
`cally definite MS, the disease progresses from an initial relapsing-
`remitting form to a secondary progressive type.1 Delaying pro-
`gression of the disease and the associated disability and cognitive
`dysfunction is one of the fundamental goals of MS therapy. To
`achieve this objective, an individualized, dynamic, long-term
`treatment strategy should be implemented along with ongoing
`monitoring of disease activity. The treatment plan should be able
`to adapt to the changing needs of the individual patient, based on
`clinical findings of disease progression, severity of MS symptoms,
`increase of disease burden on magnetic resonance imaging (MRI),
`and development of neutralizing antibodies (NAbs).
`Approved first-line therapies for relapsing-remitting MS
`include the 3 interferon beta (IFNβ) products: intramuscular (IM)
`IFNβ-1a, (IM IFNβ-1a [Avonex, Biogen Idec Inc., Cambridge,
`MA]); subcutaneous (SC) IFNβ-1a (SC IFNβ-1a [Rebif, Serono,
`Inc., Rockland, MA]); and IFNβ-1b (Betaseron, Berlex
`Laboratories, Montville, NJ) and glatiramer acetate (Copaxone,
`Teva Neuroscience, Inc., Kansas City, MO).2 Consequently, these
`drugs are used as baseline immunomodulatory agents (platform
`drugs) in the treatment of MS. These treatments are proven to
`slow various aspects of MS; however, most patients will experi-

`Neurologist recommends appropriate therapy based on:
`• Evidence-based efficacy
`• Patient lifestyle: likelihood patient will comply with dosing
`and administration regimen
`• Low immunogenicity
`• Ability for long-term treatment (suitability and tolerability)
`
`•Care management plan
`•Setting expectations
`•Patient education
`
`The decision to initiate treatment for multiple sclerosis (MS) is followed by careful consid-
`eration of the available first-line or “platform” therapies. Educating patients and setting
`realistic treatment expectations are also important factors in designing an effective long-
`term treatment plan. IFNβ = interferon beta; MRI = magnetic resonance imaging.

`the platform drug, based on symptoms and disease progression.
`Platform therapy options are the 4 drugs that are approved by the
`U.S. Food and Drug Administration (FDA) for use in relapsing MS:
`IFNβ-1b, IM IFNβ-1a, SC IFNβ-1a, and glatiramer acetate. The rel-
`ative efficacy, side effects, convenience, and compliance issues relat-
`ing to these drugs (discussed in the article by William H. Stuart in
`this supplement) should be considered when evaluating the differ-
`ent platform drugs. IFNβs are recommended as platform therapy
`because they have an impact on relapses and lesions on MRI. In
`addition, IM and SC IFNβ-1a have been shown to slow the pro-
`gression of sustained disability13-16 and IM and SC IFNβ-1b therapies
`have been shown to significantly decrease brain atrophy.17,18
`Given the long-term nature of MS treatment, the clinical aspects
`of the available platform drugs should be given careful considera-
`tion before initiating treatment. The complications that may arise
`due to the generation of NAbs to IFNβ also should be taken into
`account (for a detailed discussion, see the article by Howard S.
`Rossman in this supplement). These complications include
`reduced efficacy of the drug and cross-reactivity of NAbs that make
`switching between IFNβ products impractical. The neurologist
`must consider these factors and assist individual patients in select-
`ing the appropriate agent rather than simply providing general
`information to patients and having
