COMPANY DESCRIPTION

Sepracor is a Massachusetts based pharmaceutical company. They specialize in the development of new drugs based on the separation of chemical isomers and active metabolites from currently marketed drugs. Chemical isomers are mirror image forms of the same compound. Usually, drugs contain both mirror images in equal quantities. Sepracor found that by separating the two mirror images, new drugs could be created that work better with fewer side effects. Active metabolites are the natural breakdown products produced by the body when a drug is administered. In many cases, these metabolites also have a more favorable clinical profile than the parent drug. Sepracor calls these new drugs Improved Chemical Entities ("ICE").

The development of new drugs with improved efficacy and better side effect profiles is the goal of all pharmaceutical companies. As clinicians, we wait with great excitement for the production and marketing of Sepracor's new drugs. Sepracor has identified an impressive number of isomers that are either more potent, have easier dosing requirements or have fewer side effects than their parent compounds. All of the parent compounds are currently marketed drugs that have been approved by the FDA. Therefore, Sepracor does not waste time testing chemicals with no therapeutic potential. An efficient drug discovery process means less money spent on preclinical and clinical testing and more timely marketing of new compounds. This produces a more favorable bottom-line.

Successful pharmaceutical biotech companies are ones that can develop and protect proprietary technology and products, which will significantly impact the clinical practice of medicine. Furthermore, successful companies are able to do this in a timely and cost effective manner with particular attention to the bottom line.

Sepracor has several options for transferring their discoveries to the bottom line. First, they can license the rights for the new drug back to the company that owns the parent compound. Several such arrangements are already established including agreements with Schering-Plough for descarboethoxyloratadine (the active metabolite of Claritin) and Johnson and Johnson for norastemizole (Hismanal). Second, they can develop the new drug independently and market it on their own. To this end, Sepracor has developed a sales staff and begun to work with manufacturers. We anticipate this option will be used in the marketing of Xopenex (Levalbuterol, isomer of albuterol). The first arrangement has served the company well by providing some cash flow during their early development years. The combination of the two strategies should allow the company to post a profit in the next 2 years.

TECHNOLOGY

Some organic molecules exist as two non-superimposable mirror images. These two images are isomers and were originally named S ("sinister") for left and R for right. A racemic mixture contains equal amounts of the two isomers. Often one isomer may provide the desired therapeutic benefits, while the other may be inactive or cause side effects. By separating and purifying racemic mixtures or synthesizing only the desired isomer, Sepracor can eliminate the unwanted isomer and develop only the form that has therapeutic potential.

An active metabolite is a therapeutically active compound produced when the body metabolizes a parent drug. Some active metabolites have better therapeutic activity than their parent compound. Sepracor can separate and synthesize these metabolites to be used as new drugs.

The majority of the scientific and medical research conducted by Sepracor is directed towards discovering unique differences between isomers derived from racemates or active metabolites derived from parent drugs. Sepracor has identified several active metabolites that have significant medicinal value. Sepracor evaluates isomers and active metabolites in a highly accelerated and focused manner. Preclinical and human testing of a parent drug causes the subject to be exposed to the active metabolite. This makes it possible for Sepracor to rely upon known clinical information concerning the parent drug. This simplifies the new drug application (NDA) process, especially with regard to safety data. This compressed and directed research effort allows for early identification of advantages such as improvements in potency, onset of action, duration of activity or meaningful reductions in side effects. This allows for early and selective testing that provides insight for future clinical success and market competitiveness.

PRODUCTS

Our near term analysis of the company is based on 4 drugs that have either been approved, awaiting final approval of the New Drug Application or are in phase III clinical trials. These include three nonsedating antihistamines. Allegra (fexofenadine) is already on the market under agreement with Hoechst Marion Roussel. Its sales last year were $400 million. Descarboethoxyloratadine (active metabolite of Claritin) is in phase III trials. Claritin sales last year were $1.7 billion. Norastemizole (active metabolite of Hismanal) is also in phase III trials. Hismanal sales last year were $150 million. Sales of Hismanal were $200 million in 1996 prior to the increasing concerns about cardiac effects in some patients. In addition, Sepracor recently received an approval letter for Xopenex (levalbuterol which is an isomer of albuterol). They are apparently working towards marketing this product on their own within the next few months. Sales of albuterol (under various names) were $1.4 billion last year.

Preclinical trials have shown descarboethoxyloratadine (DCL) has the potential for much greater potency than Claritin. The launch date is planned for the year 2000.

Preclinical trials also indicate that norastemizole may be much more potent than Hismanal. Additionally, it does not appear to have the same cardiac side effects. Norastemizole
has antihistaminic onset within 30 minutes, lasts 24 hours and worked in 100% of test subjects. Phase II trials involved patients with allergic rhinitis who were given norastemizole for two days. Norastemizole treatment provided statistically significant improvement in allergic symptoms including rhinitis, sneezing, itchy eyes and nose, and scratchy throat when compared with placebo. There were no differences in incidence and severity of side effects, including cardiac events when comparing norastemizole with placebo. If the results of the trials continue to hold up under scientific scrutiny, norastemizole has the potential to be one of the best selling nonsedating antihistamines. The launch date is planned for the year 2000.

We are particularly excited about the prospects of Xopenex (Levalbuterol). Albuterol, its parent compound, is the mainstay for acute asthma treatment. Asthma affects over 15 million Americans each year. Albuterol is an effective medication but causes an unpleasant rapid heartbeat in many people. It may also cause tremors, increased blood pressure and central nervous system stimulation. These side effects sometimes limit its use in children and older adults with heart problems. Xopenex has been shown to be more effective than albuterol, with reduced side effects. The results noted in the levalbuterol Phase III trial included greater efficacy and fewer side effects. 1.25mg of levalbuterol was more potent than 2.5mg of albuterol (the standard dose). This was especially true in the sickest patients. A dose of 0.625mg of levalbuterol was as effective as the standard dose of 2.5mg of albuterol. This dose of levalbuterol cut side effects by 50%. Additionally patients treated with levalbuterol for one month showed improvement in their baseline lung function. Those treated with albuterol for one month actually showed a decrease in baseline lung function.

We believe that Xopenex has the potential to take a lion's share of the current $1.4 billion market. There will be little reason (outside of cost) to continue to prescribe albuterol once Xopenex is available. Since Sepracor is marketing Xopenex, it looks like this drug will have a significant impact on the bottom line within a year or two. They recently reached an agreement with SkyePharma PLC (Nasdaq: SKYEY / LSE: SKP) to develop metered dose aerosol formulations based on SkyePharma's proprietary inhalation technology. SkyePharma will be responsible for formulation development, scale-up to pre-production quantities and will supply clinical trial materials. Sepracor has retained commercial manufacturing rights, and has received an exclusive license from SkyePharma to distribute and sell the resulting products worldwide. Sepracor will fund SkyePharma's development costs, and SkyePharma will receive certain milestone payments on achievement of specified development objectives and future royalties on Sepracor's net sales of the products.

PIPELINE

Evaluation of potential drugs in the company's pipeline is necessary to analyze a biotechnology or pharmaceutical company. To this end Sepracor has an extremely promising future. The company has drugs in preclinical or Phase I/Phase II trials in each of the following categories: allergy/immunology, pulmonology, urology, psychiatry/neurology, gastroenterology and infectious disease (including antibacterial and antifungal).

Sepracor has another antihistamine in the pipeline. This is (-)-certirizine which is a single isomer of Zyrtec, a "less sedating antihistamine." Zyrtec had $550 million in sales last year. Sepracor owns (-)-certirizine patent and is currently in preclinical studies. The company is looking for decreased sedation with the single isomer.

Sepracor also has a long acting bronchodilator it is working on for asthma. (R,R)-formoterol is a single isomer of Foradil/Atock. Formoterol fumarate exerts a bronchodilatory effect that is rapid in onset (within 1 to 3 minutes) and still significant 12 hours after inhalation. In vitro formoterol inhibits the release of histamine and leukotrienes from passively sensitized human lung tissue. Some anti-inflammatory properties, such as inhibition of edema and inflammatory cell accumulation, have been observed in animal experiments. These drugs are used in the treatment of asthma in Europe and Japan and had sales last year of $140 million. A comparable drug in the United States is Serevent. The sales of Serevent worldwide by GlaxoWellcome were £406 million for 1997 ($691 million at current exchange rates) and £226 million for the first half of 1998 ($385 million at current exchange rates) this represents 28% growth over the comparable year ago period. (R,R)-formoterol is currently in Phase II trials. The company believes that the single isomer version will have a rapid onset and will be longer acting on the lungs. In the November 1997 issue of New England Journal of Medicine, results from a clinical trial in asthma patients showed the addition of (R,R)-formoterol to low dose budesonide (an inhaled steroid, commonly used in asthma/COPD) reduced the rate of mild exacerbations by 40% and of severe exacerbations by 26%.

In the urologic arena Sepracor currently has two drugs. They are the furthest along with (S)-oxybutynin, a single isomer of Ditropan. Ditropan is used to assist bladder control in patients with urinary incontinence. Sepracor's drug is currently in Phase II trials with a target launch in 2000. Ditropan sales were $134 million in 1997. (S)-oxybutynin should decrease the side effects that include dry mouth, dizziness, nausea and palpitations thus increasing the number of patients who will stay on the drug.

The other drug is (S)-doxazosin, a single isomer of Cardura. Cardura is a medication that is used for two diseases, hypertension (elevated blood pressure) and benign prostatic hypertrophy (symptomatic swelling of the prostate). Sepracor seems to be looking, at least initially, to the use of the drug for benign prostatic hypertrophy. 1997 sales of the parent drug are $600 million. Orthostatic hypotension and erectile dysfunction are both reduced with (S)-doxazosin. Improvement of these side effects increase the likelihood of patients continuing the medication.

The drugs that Sepracor is developing for psychiatry and neurology are very interesting. The drugs that cast the biggest shadow are the isomers of Prozac, (R)-fluoxetine and (S)-fluoxetine. Sepracor announced (R)-fluoxetine began Phase I clinical trials October 14, 1998. In preclinical trials, (R)-fluoxetine was shown to treat Depression but with a shorter half-life. A shorter half-life means a faster "wash-out" period. This makes it much more competitive with other antidepressants in the same class including Zoloft (growing 15% a year) and Paxil (growing 30% a year). The shorter half-life will increase the likelihood of prescribing by physicians who have concerns about the long "wash-out." These potential benefits offer greater suitability for treating the elderly as well as pediatric and adolescent patient groups. (R)-fluoxetine may also be well suited for the treatment of new indications such as premenstrual syndrome (PMS) and treatment of patients with eating disorders such as bulimia, anorexia nervosa and obesity. The sales of the parent drug Prozac were $2.6 billion last year. The sales for the SSRI class of antidepressants were $6.5 billion last year.

(S)-fluoxetine is currently under study (Phase II trials) for use in migraine headaches. The market for migraine prophylaxis is huge. Currently prophylactic medications include beta blockers and Ca channel blockers, both of which are high blood pressure medications and can have a number of side-effects including orthostasis, edema and impotence. The SSRIs are also used in this capacity as an off-label indication. There are 11.3 million patients in the United States who suffer from migraine headaches.

(+)-zopiclone is the isomer of Imovane, a short-acting hypnotic agent for sleeping disorders used in Europe. Sales of Imovane last year were $144 million. The drug would be the second non-benzodiazepine treatment for sleeping disorders in the U.S. Sleep disorders affect 56 million people in the United States. The only currently approved non-benzodiazepine treatment for sleeping disorders is Ambien, which had sales last year of $500 million. (+)-zopiclone shows potential for reduced anticholinergic side effects, including dry mouth and urinary retention when compared to the parent drug. A patent was issued for (+)-zopiclone August 1998. It is currently in pre-clinical trials.

(S)-sibutramine is an isomer of Meridia, a new weight loss medication. The market for a safe and effective weight loss medication is incredible. Currently there are 58 million Americans who are obese. (S)-sibutramine shows potential for reduced anticholinergic side effects including dry mouth and constipation. It is currently in pre-clinical trials.

(R)-buproprion is an isomer of Zyban/Wellbutrin. The parent drug is used as an antidepressant under the trade name Wellbutrin and used for smoking cessation under the name Zyban. (R)-buproprion is currently in preclinical trials and has potential for reduced incidence of seizures, dry mouth and insomnia.

Sepracor has a number of drugs in development for gastrointestinal problems. One of the most important is norcisapride, a metabolite of Propulsid. Propulsid is used for GERD (gastroesophageal reflux disease A.K.A heartburn). Sales of the parent drug in 1997 were $1 billion. Norcisapride is currently in preclinical trials. The drug promises improved potency and less frequent dosing without the adverse side effects of cardiac toxicity. The drug has the potential to treat other medical problems including emesis (nausea and vomiting), irritable bowel syndrome, and bulimia giving it market potential in the $4 billion range.

(R)-ondansetron an isomer of Zofran has the potential for reduced cardiovascular side effects and improved efficacy in the control of emesis. The sales of the parent drug last year were $600 million. It is currently in preclinical trials.

(S)-lansoprazole is the isomer of Prevacid. It is one of two main proton pump inhibitors currently in use in the U.S. for gastritis, peptic ulcer disease and GERD. (S)-lansoprazole is currently in preclinical trials and shows promise for improved dosing consistency and efficacy. The parent drugs sales were $1 billion last year.

(-) pantoprazole is the isomer of Pantozol, another proton pump inhibitor. The drug is also in preclinical trials and has potential for consistent plasma levels that may lead to better efficacy and safety. Sales were $1 billion last year.

Sepracor has good candidates in the field of infectious disease. The antibacterial drug is (R)-lomefloxacin, an isomer of the parent drug Lomebact/Maxaquin. It belongs to the class of drugs known as the fluoroquinolones, a group of broad-spectrum antibiotics. The improvements expected with the single isomer version include improved antimicrobial activity and decreased photosensitivity. The drug is in preclinical trials.

(2R,4S)-itraconazole is an isomer of Sporanox, an oral antifungal. The parent drug had sales of $550 million last year. This is increasing at a rapid pace because of the dearth of treatments for Onychomycosis prior to the introduction of the oral antifungal medications a few years ago. Companies with oral antifungals have also been advertising. The isomer has reduced cardiovascular side effects and is in preclinical trials.

MANAGEMENT

Sepracor has an impressive executive staff and board of directors. The executives include two PhD's and one MD among their ranks. They have made what we think are excellent management decisions in the past and will probably continue to do so. The board of directors includes the former presidents, vice presidents, or CEO's of five well-known pharmaceutical companies. The company also has ownership of BioSepra (BSEP) (64%, makes chromatography equipment and media), HemaSure (HMSR) (37%, makes equipment for blood product purification) and Versicor, Inc. (22%, anti-infective drugs). It is also the majority owner of Sepracor Canada Limited.

COMPETITORS

Sepracor's competition in the field of chiral chemistry includes Chiroscience PLC of Cambridge, England, which also seeks to improve existing dual-isomer drugs. However, both companies in this field need extremely strong expertise in isolating and purifying stereoisomers in order to achieve success, and the two companies seem to be focusing on different products to re-engineer. It's also quite likely that there's room for more than one company in this niche.

RECOMMENDATION/OUTLOOK

Obviously, this company has a lot of potential for blockbuster drugs and even bigger earnings. We have been impressed with Sepracor's strategy as well as their patents and pipeline. Worldwide sales of antihistamines to treat allergies exceeded $3 billion in 1997, and the antihistamine market is expected to grow to $6 billion over the next five years. Asthma continues to affect increasing numbers of Americans each year. By 2001, over 17 million people could comprise the asthma medication market in the U.S. alone. The market for albuterol was over $1.4 billion in 1997. The market for long acting bronchodilators was over $800 million worldwide in 1997. These facts combined provide a rosy outlook for Sepracor's main products.

Sepracor's CFO David Southwell agreed with analysis which estimates the company will turn profitable in 2001 and earn about $5 per share by 2002. A good measure of the financial health of developmental stage biotech companies is the amount of cash on the balance sheet in comparison to the burn rate. The larger the ratio, the longer the company can survive while waiting for their products to come to market. Most analysts agree that a minimum of 8 quarters is necessary. He said the company's burn rate, which looks to be $90 million, is actually closer to $300 million when one takes partnership contributions into account. At a burn rate of $90 million, the company has over 2 year's worth of cash on their balance sheet.

We based our estimates of 2001 earnings on the approval and marketing of 5 drugs that we believe have the best potential for successful end development. Our basic formula takes 1997 sales for comparable drugs adds in a reasonable growth rate, a conservative market share for Sepracor's new drug, takes into account any agreements with other pharmaceutical companies, and discounts for taxes and present market value.

Using this formula, we figure conservative earnings of $9.29 per share in 2001. Using a "worst case" scenario, we figure earnings might be as low as $5.06 per share in 2001. Applying a P/E multiple of 25, our target price for 2001 is $232.25 per share (worst case $126.50 per share). Discounting by 40% gives a 12 month target of $139.35 per share (worst case $75.90). Based on a recent price of $64 per share this represents 118% (worst case 19%) return. Not too shabby!
