PharmaVOICE approved for treating cataplexy. Of the esti mated 140,000 Americans who suffer from narcolepsy, between 60% and 90% experience cataplexy. Orphan Medical Inc. developed Xyrem under the FDA’s Orphan Drug Act of 1983, which provides market exclusivity to companies that develop products for small, underserved patient populations. While the Orphan Drug Act provides some financial advantages to the developing compa ny in the form of tax credits, which are available for testing expenses for drugs, vaccines, diag nostic drugs, or preventive drugs used to treat rare diseases or conditions, bringing Xyrem to market wasn’t an easy task. Xyrem is a formulation of the chemical compound gamma hydroxybutyrate, or GHB, which has been around since the 1960s. GHB, a central nervous system depressant, was developed as an anes thetic and hypnotic for use in humans in Europe, but was soon withdrawn due to adverse side effects. Later, GHB gained notoriety because of its potential for abuse and illicit use. The journey for Orphan Medical began in 1994 when the FDA approached the company to gauge its interest in developing GHB as a treatment for narcolepsy. The drug previously had been under development for narcolepsy by , a symptom of the chron ic sleep disorder narcolepsy, is an alarming con dition, resulting in sudden, brief episodes of muscle weakness or paralysis brought on by strong emotions such as laughter, anger, sur prise, or anticipation. In severe attacks, the patient may collapse and be unable to move for up to several minutes. Until recently, there were no approved treatments for people with this condition. That changed July 17, 2002, when the Food and Drug Administration approved Xyrem (sodium oxybate) oral solution for the treat ment of cataplexy. Xyrem is the only drug Orphan Medical’s development of Xyrem,a 40yearold compound, is providing relief to thousands of people who suffer from cataplexy, a debilitating sleep disorder CATAPLEXY

another company, but had been dropped. After researching the proposal, executives at Orphan Med ical expressed interested in developing GHB, but were concerned about the propri etary situation. Full sup port was given to the pro ject after it was discovered that the drug was eligible to receive orphan drug sta tus. Orphan Medical has created a niche in the industry by acquiring, developing, and marketing pharmaceuticals of high medical value for inade quately treated and uncom mon diseases treated by specialist physicians. “GHB is a compound that has been around since the early 1960s, and only now has been approved by the FDA for a therapeutic use,” says John Bullion, CEO and chairman of Orphan Medical. “Since the compound has been in the public domain, no pharma company was willing to develop it. Were it not for the protection afforded by the Orphan Drug Act, we wouldn’t have developed the drug either.” Orphan drug status is given to medica tions that treat a rare disease or condition — defined as one that affects less than 200,000 persons in the U.S. (for more information see box on page 58). Soon after Orphan Medical began develop ing GHB, serious concerns emerged because of an explosion of reports surrounding abuse. “When we began development, one thing we considered was the abuse characteristic of the drug,” Mr. Bullion says. “Most GHB abuse appeared to be in the weightlifting and body building community because it hadbeen report ed to be a growthhormonereleasing agent.” The compound GHB originated about 40 years ago when it was synthesized as a peripher ally administered agonist of the inhibitory neu rotransmitter, gammaaminobutyric acid. It was used as an alternative anesthetic to aid in surgery because of its ability to induce sleep and reversible coma. However, it had little analgesic effect, and onset of coma often was associated with seizure activity, including tonicclonic jerking movements of the limbs or face. During the 1980s, GHBwas sold in health XYREM solution food stores, training gyms, fitness centers, and on the Internet. In addition, it was promoted as a natural treat ment for insomnia and to induce weight loss. In 1990, the FDA issued a press release warning against GHB, stating that it was illegal and dangerous. Illicit GHB use has been associated in combination with ecstasy and other ille gal drugs as a euphoric drug, and in reported date rapes as a sedative. The drug is odor less and colorless, making it impossible to detect when added to a drink. According to the Drug Abuse Warning Network, a division of the Substance Abuse and Mental Health Services Administration, the number of patients treated for GHB overdose or GHB related problems in hospital emergency departments in 1994, when Orphan Medical began developing the drug, was 55. By 1998, the num ber was 1,282 and by 1999, the number of GHBrelated medical emergencies was reported at 2,973. More than 70% of emergency department episodes involving GHB were found to involve more than one drug; alcohol was the most fre quent substance mentioned in combination episodes. The substance has been linked to about 60 deaths, mostly in combination with alcohol. The significant increase in the incidence of GHB abuse led to a movement to petition Congress to make the compound a Schedule I drug — drugs that have a high potential for abuse, that require greater storage security, and have a quota on manufacturing, among other restrictions. Schedule I drugs are only available for research and have no approved medical use. After learning of this petition, company executives began working with Congress and the FDA to find a way to resolve the situation. “We got wind of the bill and approached those in Congress seeking to make GHB a Schedule 1 compound,” Mr. Bullion says. “We explained that the compound had shown sig nificant efficacy in the treatment of narcolep sy, and Congress ultimately approved the FDA’s proposed bifurcated schedule.” In February 2000, the passage of the Hillo ry J. Farias and Samantha Reid DateRape Drug Prohibition Act of 2000, named for two teenagers who died after the substance was slipped into their soft drinks, amended the Controlled Substances Act and created a bifur cated schedule for GHB, the first for any drug. According to the bifurcated schedule, when intended for abuse or misuse, GHB is a Sched ule I agent. If it is used as an approved medi cation, such as Xyrem, it is classified in the Schedule III category. Schedule III and Sched ule IV drugs are available by prescription, may have five refills in six months, and may be ordered orally. In addition, Xyrem’s distribu tion is governed by Subpart H of the Food, Drug & Cosmetic Act. Subpart H provides for restrictions on the marketing, distribution, and risk management of pharmaceuticals. “The bifurcated schedule for GHBwas a very appropriate response to the situation — allow ing patients access to the medication for treat ment of a serious, debilitating disease, and pro viding an appropriate penalty to anyone abusing the drug,” Mr. Bullion says. “We worked with Congress to shape that legislation and we think . Americans with narcolepsy: Approximately 140,000 Americans, however,only about 75,000 are diagnosed and treated, with some reports suggesting diagnosis is as low as 50,000 people. . Narcoleptics with cataplexy:60% to 90%. . The mean number of years between the onset of symptoms and correct diagnosis: 14 years. . Age and gender factors: Narcolepsy occurs in both men and women at any age,although symptoms are usually first noticed in teenagers or young adults between the ages of 15 and 30. . Heredity factor: 8% to 12%of people with narcolepsy have a close relative with the disease. . Economic impact: Sleep deprivation and untreated sleep disorders are estimated to cost more than $100 billion annually in lost productivity, medical expenses, sick leave, and property and environmental damage. Market Facts Mark Perrin As part of our overall commercialization efforts, there is a large medical education component … wewill undertake a major CME initiative in the understanding of narcolepsy. PharmaVOICE XYREM solution 56 O c t o b e r 2 0 0 2 PharmaVOICE it is a perfect balance between needed patient therapy and potential abuse.” In addition to working with Congress and the FDA to create the bifurcated scheduling, the company worked with law enforcement agencies to make it difficult for potential abusers to get hold of the product. “Throughout the development program we consulted with institutions such as the DEA, law enforcement agencies, and the toxicology community — people who deal with the abus ing populations,” says Bill Houghton, M.D., VP, chief medical officer, and chief scientific officer of Orphan Medical. “As a result, we pro posed, as part of the approval process, a very restricted distribution program for the post approval availability of Xyrem so that we could proactively ensure that the patients who really needed the drug had it, at the same time mak ing it as impossible as we could for misplace ment or diversion of the drug.” Restricted Access In an effort to ensure that only narcoleptic patients would receive Xyrem, Orphan Medical created a limited distribution plan known as the Xyrem Success Program. Under the arrangement, Xyrem only is available to pre scribers through a single centralized pharmacy. Orphan Medical is making Xyrem available to the public through an exclusive distribution arrangement with Express Scripts’ Specialty Distribution Services (SDS) subsidiary. Once Xyrem is manufactured it is shipped to Express Scripts’ SDS, which will provide pharmacy services to patients, collect patient registry information, provide reimbursement support, distribute informational materials, and serve as a resource for product and educational program information. Prescriptions written for Understanding Narcolepsy THE APPEAL OF A DRUG LIKE XYREM IS APPARENT, GIVEN THE DEVASTATING IMPACT NARCOLEPSY, AND THE CONDITION CATAPLEXY,CANHAVEONTHELIFEOFTHEAFFECTED INDIVIDUAL. Narcolepsy is a disabling neurological disorder of sleep regulation that affects the control of sleep and wakefulness. Normally,when an individual is awake, brain waves show a regular rhythm.When a person first falls asleep, the brain waves become slow er and less regular, a sleep state called nonrapid eye movement (NREM) sleep.After about an hour and a half of NREM sleep, the brain waves begin to show a more active pattern again, even though the person is in a deep sleep, a state called rapid eye movement (REM) sleep, which is when dreaming occurs. In narcolepsy, the order and length of NREM and REM sleep periods are dis turbed, with REM sleep occurring at sleep onset instead of after a period of NREM sleep.Also,some of the aspects of REM sleep that normally occur only dur ing sleep — lack of muscle tone, sleep paralysis, and vivid dreams — occur at other times in people with narcolepsy. It can be described as an intrusion of the dreaming state of sleep, REM, into the waking state. Symptomsgenerally appear in peoplebetween15yearsoldand30 years old.The four classic symptoms of the disorder are excessive day time sleepiness, sleep paralysis, hypnagogic hallucinations, and cata plexy — sudden,brief episodes of muscle weakness or paralysis often brought on by strong emotions such as laughter, anger, surprise, or anticipation. For patients with severe cataplexy, the episodes can hap pen frequently throughout the day and with little provocation. “I have cataplexy quite severely, and without any medication I can have anywhere from 20 to 40 complete collapses in a day,”says Mali Einen,clini cal research coordinator at the Center for Narcolepsy Research in the Stan ford Sleep Disorders Center andaXyrempatient.“Even thinking almostany thing can cause a collapse, it doesn’t necessarily take extreme emotion. Instead cataplexy can be triggered by any proactive thought, if I see some body I recognize, I can have a complete loss of muscle tone and collapse.” In the U.S., about 140,000 people have narcolepsy.While 100% of peo ple with narcolepsy suffer from the exces sive daytime sleepiness symptom of nar colepsy, about 60% to 90% of those patients also have cataplexy. Cataplexy comes on as an immediate attack that lasts for minutes.The patient can lose control of multiple muscle groups including neck, arms, and legs during an attack.The brief attacks can occur frequent ly enough to preventpatients from carrying on a normal life, since any social interaction can cause attacks. This can lead to many patients withdrawing from any situation where they may experience emotion. “Before taking Xyrem, I was on the brink of disability,” says Bob Cloud, executive director of Narcolepsy Network and a Xyrem patient.“I couldn’t leave the office without fear of falling down in the streets.Sometimes I couldn’t hold a telephone. I fell every place imaginable.That was the reason I began tak ing Xyrem,and after several weeks the cataplexy symptoms disappeared by about 90%.” The usual treatment for narcolepsy includes symptomatic treatment of excessive daytime sleepiness and sleep attacks with stimulants or drugs such as Cephalon Inc.’s Provigil, a wakefulnesspromoting agent that was approved in December 1998 for the treatment of excessive day 140,000 people have narcolepsy. While 100% of people with narcolepsy suffer from the excessive daytime sleepiness symptomof narcolepsy,about 60% to 90%of those patients also have cataplexy. XYREM solution PharmaVOICE Xyrem only can be filled by Express Scripts, which verifies that the physicians are in good standing, makes sure that the physician has received the Xyrem physicianeducation pro gram, verifies that the patient has received a patienteducation program, contacts the patient to ensure that they are prepared to receive the drug, and then ships the product to the patient using a courier service. “The single, mailorder pharmacy will cap ture patient names and data in a patient reg istry as well as data on the physicians,” Mr. Bullion says. “Impropriety should be readily apparent and that information will be avail able to law enforcement agencies. This is quite different from having upwards of 100,000 retail pharmacy distribution points. This is a very direct distribution system: from manu facturer to pharmacy to patient.” Orphan Medical executives believe the sys tem not only will help prevent the drug from getting into the wrong hands, but will help educate patients and physicians, as well as pro vide the compa ny with impor tant prescribing data and trends. “We view this program as a very nice continuum,” says Mark Perrin, executive VP and chief commer cial officer for Orphan Medical. “Even though the distribution program was set up as part of a riskmanagement system, one that clearly ful fills our obligations, it is a highly comprehensive patient and physician education program that provides us with a clear understanding of how the product is being prescribed as well with other valuable information.” While GHB has been the subject of nega tive publicity, and doctors will need to go through a rigorous prescribing process for Xyrem, those in the medical community don’t believe the drug’s success will be hampered. time sleepiness associated with narcolepsy. Provigil,however, is not indi cated for, and does not treat, the other symptoms of narcolepsy. Before the approval of Xyrem,the symptoms of cataplexy,sleep paraly sis, and hypnagogic hallucinations were typically treated with anticata plectics — tricyclic antidepressants or selective serotonin reuptake inhibitors usedoff label.Patients suffering fromnarcolepsy that experience cataplexy typically take a combination of stimulants and antidepressants. For cataplexy, treatment with antidepressants is used because the drugs are known to suppress REM sleep.Cataplexy is a pathological equiv alent of REM sleep atonia unique to narcolepsy.Although antidepressants suppress REM sleep, the drugs have a significant sideeffect profile. “With Xyrem I don’t have the side effects that the various antidepres sants caused,such as dry mouth,gastric complications, and bumps on my eyeballs from dry eyes,” Ms. Einen says. “I don’t have any of these side effects with Xyrem and more of my cataplexy is curbed as well.” Xyrem, while not sideeffect free, was found to have fewer and more tolerable side effects than commonly used anticataplectics. The primary side effects associated with Xyrem are confusion,dizziness, nausea, occa sional vomiting, occasional bedwetting, and occasional sleepwalking.The FDA’s Center for Drug Evaluation and Research drug information also lists trouble breathing while asleep,abnormal thinking,depression,and loss of consciousness. “Certainly Xyrem has side effects,”says Bill Houghton,M.D.,VP,chief medical officer, and chief scientific officer of Orphan Medical.“But these are balanced by very strong clinical efficacy and the benefits in treating narcolepsy,so it certainly represents a satisfactory sideeffect profile.” Xyrem also has been found to have an excellent tolerance profile. With antidepressant treatments, in addition to the side effects, patients often build tolerance to the antidepressants and doses are increased to obtain clinical effectiveness. Also, in studies with Xyrem, the drug was not found to cause any addictive behavior or withdrawal symptoms when used in a con trolled manner. “In clinical research,there was no evidence of the development or resurfacing of symptoms at any given dose over time,” says Jed Black, M.D.,director of the Stanford Sleep Disorders Clinic. “One of the ways to get a sense for tolerance is to record how much rebound occurs when the medication is withdrawn. The abrupt discontinuation of GHB does not result in any rebound cataplexy, unlike any other anti catapletic medication.With Xyrem there is no evidence of withdrawal symptoms.” Before taking Xyrem, I was on the brink of disability. I couldn’t leave the office without fear of falling down in the streets.Sometimes I couldn’t hold a telephone. I fell every place imaginable.That was the reason I began taking Xyrem,and after several weeks the cataplexy symptoms disappeared by about 90%. BOB CLOUD XYREM solution “At this point, I think the medical commu nity has respect for the agent and wants to mon itor it closely to make sure there is no misuse or illicit use,” says Jed Black, M.D., director of the Stanford Sleep Disorders Clinic. “There’s been no abuse of the drug within the narcolepsy patient population. There doesn’t appear to be any addiction potential in these patients and there have been no dose escalation problems, so The term “orphan drug” refers to a product that treats a rare disease affecting fewer than 200,000 Americans or affecting more than 200,000 persons in the U.S., but there is no reasonable expectation that the cost of developing and making available a drug for disease or condition will be recovered from sales in the U.S. of such a drug. The Orphan Drug Act was signed into law Jan.4, 1983, to stimulate the research, development, and approval of products that treat rare diseases. This mission is accomplished through several mechanisms, including: Pharmaceutical company sponsors are granted seven years of marketing exclusivity after approval of its orphan drug product. Pharmaceutical company sponsors are granted tax incentives for clinical research they have undertaken. The FDA’s Office of Orphan Products Development coordinates research study design assistance for sponsors of drugs for rare diseases. The Office of Orphan Products Development, division of the Food and Drug Administration, encourages sponsors to conduct open protocols,allowing patients to be added to ongoing studies. Grant funding is available to defray costs of qualified clinical testing expenses incurred in connection with the development of orphan products. The Orphan Drug Act From 1983 to 2000, there have been 1,063 orphan designations, and 218 orphan marketing approvals — 20.5% of tested orphan products received FDA marketing approval. 2002 Orfadin (nitisinone) for treating tyrosinemia type 1 — Swedish Orphan AB Remodulin (treprostinil) for treating pulmonary arterial hypertension — United Therapeutics Corp.

Recently Approved OrphanDrugs 1 2 3 4 5 PharmaVOICE XYREM solution I think the medical commu nity feels pretty good about Xyrem.” Analysts believe the focus will be on the benefits of the drug. In clinical trials, Xyrem has been shown to reduce cataplexy attacks by 70% and is able to maintain its effect long term. “Most physicians who are in a position to prescribe the drug are wellaware of the therapeutic benefits and they are just waiting for this drug to be launched,” says Donald Ellis, Pharm.D., partner at Thomas Weisel Partners LLC. Waking Up the Market Orphan Medical plans to launch Xyrem in mid October of this year with the backing of a dedicated salesforce of more than 30 experienced sales represen tatives that the company has hired specifically to detail the compound. “Given the sophisticat ed nature of the drug, the launch is going to be chal lenging, yet very reward ing,” Mr. Perrin says. “The company evaluated options on how to best commercial ize Xyrem and we elected to hire a dedicated group of specialty representatives. We’re fielding a team of about 36 people and they will be solely responsible for Xyrem, they won’t be involved in any of Orphan Medical’s other products.” The Xyrem salesforce will target the nearly 600 accredited sleep centers across the U.S. Orphan Medical has compiled a proprietary database of physicians who have high numbers of patients with sleep disorders. The salesforce also will target these 3,000 to 4,000 physicians who comprise three specialty groups: neurologists, psychiatrists, and pulmonologists. In addition, the company will supplement salesforce calls with traditional nonpersonal detailing, including direct mail and journal advertising. Because the product is a Subpart H drug with a blackbox warning, the compa ny is prohibited from doing any directtocon sumer advertising. In addition, Orphan Medical has plans to partner with a major university to undertake a comprehensive CME initiative to help the pre scribing community better understand nar colepsy and the debilitating effects of cataplexy. The company plans to continue to align itself closely with patient advocacy groups, which the company worked with throughout Xyrem’s development. “When working with Congress, we also worked very closely with patient groups such as the Narcolepsy Network, the National Sleep Foundation, and other patient groups,” Mr. Bul lion says. “Early on we began working with John Bullion Were it not for the protection of the Orphan Drug Act of 1983,we wouldn’t have developed the drug. XYREM solution 60 O c t o b e r 2 0 0 2 PharmaVOICE these groups to learn more about the condition, the patients, and the idiosyn crasies of the marketplace. We’ve worked closely with patient groups to discover what their other needs may be. Patient groups are going to be very important by let ting the narcolepsy com munity know that Xyrem is available for cataplexy.” Analysts believe that Xyrem will be well received and have a strong uptake by cataplexy patients. Furthermore, industry experts expect that patients currently being treated with other remedies, such as antidepressants, will convert to Xyrem and that the market will expand because of the drug’s strong efficacy and safety profile. “We believe that Xyrem’s efficacy and side effect profile should support uptake of the drug upon its launch among this population,” says Andrew Forman, senior analyst and man aging director in the healthcare research group of Friedman, Billings, Ramsey & Co. “Xyrem likely will increase the size of the market as patients with milder symptoms, who current ly choose not to take antidepressants due to their side effects, decide to try Xyrem as an advancement in the treatment of cataplexy. We forecast the cataplexy market will be more than $100 million, in which Xyrem would be the only approved treatment.” According to analyst forecasts, Xyrem is expected to generate sales of $11 million in 2003, $31 million in 2004, $54 million in 2005, and $81.9 million in 2006. Another factor that encourages analysts is Orphan Medical’s development of Xyrem for an additional indication: the treatment of excessive daytime sleepiness in narcolepsy. “While we had very positive results in the reduction of cataplexy, we were surprised to see positive efficacy results in the management of excessive daytime sleepiness,” Mr. Bullion says. “Xyrem appeared to provide a positive effect in reducing excessive daytime sleepiness, incrementally to the effect provided by stimu lants. Since we used a subjective, though vali dated measurement, as a secondary endpoint in our pivotal study, we are conducting anoth er trial using objective measures of the prima ry endpoint: the reduction of excessive day time sleepiness.” A Phase IIIb study is under way and expected to be completed by the end of 2003, with a supplemental new drug application fil ing in 2004 and potential approval in 2005. “The addition of this indication to the drug’s label would broaden Xyrem’s utility to all narcolepsy patients,” Mr. Forman says. “While there would be significant overlap with the cataplexy market, we conservatively estimate that an excessive daytime sleepiness indica tion could expand the mar ket by 20% or more. We believe the opportunity for patients to treat two of their symptoms with one drug will help drive growth.” This additional indication would also be covered under the Orphan Drug Act. Xyrem only is approved for marketing in the U.S., however, the company is actively seeking marketing partners in Europe and Japan. Upon the U.S. launch of Xyrem, Orphan Medical will have seven orphan drugs on the market: Antizol for ethylene glycol or methanol poisoning, or for use in suspected ethylene gly col or methanol ingestion, either alone or in combination with hemodialysis in humans; AntizolVet for ethylene glycol or suspected ethylene glycol ingestion in dogs; Busulfex for use in combination with cyclophosphamide as a conditioning regimen prior to allogenic hematopoietic cell transplantation for chronic myelogenous leukemia; Cystadane for homo cystinuria, a genetic disease; Elliotts B Solution, for intrathecal administration of methotrexate sodium and cytarabine for the prevention or treatment of meningeal leukemia or lympho cytic lymphoma; and Sucraid for sucrase defi ciency, a genetic disease.
