Your costs can change dramatically when new medications come to market. So we keep careful watch on new drug launches, as well
as on medications expected to gain approval in the next several months.
The Pipeline Report contains a sampling of the initial assessments of recent and upcoming medication launches from news outlets andexpert analysts around the industry. We try to capture some of the variables that will determine the ultimate impact of a new drug,including whether a medication represents a substantial advance in the science, its relative place within its therapeutic class and othermarket dynamics.
This report contains only a few of the most prominent new medications. If you would like to view a more extensive, more clinically-
oriented list, please click here to download from OptumRx.
If you have questions about our strategies or programs related to the new medications, please contact your OptumRx representative.

Tecfidera (dimethyl fumarate)Biogen Idec
Oral medication used to treat adults with the most common form of multiple sclerosis (MS).1/td> Current Status
U.S. Food and Drug Administration approved March 27, 2013.1 Prior to 2010, most MS disease-modifying therapies were injectable therapies:• Betaseron (interferon beta-1a (IFNβ-1a)) was introduced in 1993 and subsequent versions of interferon beta have been approved since then2 • Copaxone® (glatiramer acetate injection), a non-interferon based therapy, was approved in Similar Medications
• 2010: Gilenya®, (fingolimod) first oral agent for the treatment of MS 2• 2012: Aubagio® (teriflunomide) second oral agent for MS 2 • MS affects nearly 400,000 individuals in the United States. Onset typically occurs between age 20 • Analysts expect Tecfidera to be a blockbuster because of its combination of efficacy and relative safety plus the convenience of being a pill.3 • On price, Tecfidera is priced midway among the current oral MS treatments at $54,900 (wholesale) per patient per year. That is slightly less than 10% below Gilenya and 14% above Aubagio.2 • Note that all of these prices are considerably higher than for earlier treatments. The average cost to treat an MS patient in 2010 was $24,113. 4 • During the clinical studies of Tecfidera the side effects experienced appeared to be relatively mild Potential Market
by comparison to existing drugs. 5 And while its ability to reduce the rate of relapse is similar to thecompeting oral drugs, it is much better than that of the existing injectibles.5 • Reports indicate that doctors with early MS patients may be waiting for this treatment to become available.5 In part due to this, financial analysts expect that Tecfidera could capture as much as20% of the MS market in its first year.7 • Subsequent projections have sales growing rapidly by 2018, with consensus global sales at around • Currently, the world market for MS drugs is $14 billion per year.3 June, 2013 Issue 1
• Among existing therapies, the various interferon formulations and glatiramer acetate (GA) have • Even today, no single MS agent has emerged as the consensus “first-line” treatment. 2 • Now with a third oral agent on the market, some speculate that the traditional injectable therapies will begin to be replaced by the oral medications– even at a much at a higher cost. 2 1.

Intravenous medication used to treat adults common forms of multiple sclerosis (MS).2 • alemtuzumab (previously marketed as Campath®) is licensed to treat leukemia, and has been used off-label in patients with multiple sclerosis for many years.3 • Genzyme pulled Campath off the market in September 2012 to prevent its unauthorized use as an Current Status
• FDA has accepted for review Genzyme’s supplemental Biologics License Application (sBLA). 1• Genzyme expects FDA action in the second half of 2013. 1 There are 5 self-injectable and 2 infused disease-modifying agents on the market: 4Self-injectable:• Avonex® (interferon beta-1a)• Betaseron (interferon beta-1b)• Copaxone® (glatiramer acetate injection (GA)• Extavia® (interferon beta-1b) Similar Medications
• Novantrone® (mitoxantrone)• Tysabri® (natalizumab) Genzyme is pursuing a two-prong strategy to turn alemtuzumab into a major MS drug under theLemtrada brand name:5• ◦ First, it has withdrawn alemtuzumab for leukemia use under the Campath brand in both the U.S.
and in Europe. Campath and Lemtrada are the same drug given at a different dosage.6 ◦ Second, a license extension to approve alemtuzumab for multiple sclerosis opens up a more [For more information see “Pricing the market,” below.]
Pricing the market
• When used for leukemia treatment, alemtuzumab (as Campath) costs around $60,000 for a year’s
treatment (three times a week for up to 12 weeks).
• However, MS patients would need only a fraction of the cancer dosage – just 5 consecutive days and then one year later another 3 days. At that rate, an MS-sized dose of alemtuzumab would cost • As noted in the Tecfidera review above, $6,000 would be just one quarter of the recent average Potential Market
cost of the existing approved injectable MS agents ($24,113/year).
• By eliminating Campath Genzyme prevents cheaper, off-label MS use.
• Obtaining the MS license extension, the company could begin to charge an MS-market price for Lemtrada matched not only against existing injectibles, but also against the newer oral MS drugs, which range from $60,000 to $48,000 per year.
• While Genzyme has not yet released its prices, Lemtrada is expected to grow to between $400 million to $600 million by 2018. By comparison, in 2011 Campath yielded sales of $76 million. 5 1.
