Total Revenues Up 19 Percent Year-Over-Year

Total Revenues Up 19 Percent Year-Over-Year Biogen's Third Quarter 2003 Reported EPS of $0.36 Increased 30 Percent Year- Over-Year; Operating EPS of $0.51 Increased 39 Percent Year-Over-Year CAMBRIDGE, Mass., Oct. 28 /PRNewswire-FirstCall/ -- Biogen, Inc. today announced financial results for the third quarter of 2003. (Logo: http://www.newscom.com/cgi-bin/prnh/19990824/BIOLOGO ) For the three months ended September 30, 2003, total revenues were $342 million, an increase of 19 percent over the third quarter of 2002. * AVONEX(R) (Interferon beta-1a) worldwide sales were $298 million, an increase of 14 percent over third quarter 2002. U.S. sales were $204 million, and international sales were $94 million. * AMEVIVE(R) (alefacept) sales were $12 million. * Royalties were $29 million, an increase of seven percent over the third quarter 2002. Reported net income increased 31 percent to $55 million, or $0.36 earnings per share, in the third quarter of 2003, from $42 million, or $0.28 earnings per share, in the third quarter of 2002. Operating earnings per share was $0.51 in the third quarter of 2003 versus $0.37 in the same period of 2002, an increase of 39 percent. Operating results in the third quarter of 2003 exclude an upfront payment related to the licensing of a second-generation fumarate derivative from Fumapharm AG, merger-related expenses, gains on the sales of securities, and an equity writedown. On an after-tax basis, these charges were $22 million, or $0.14 per share. See attached "Operating Condensed Consolidated Statements of Income" tables for a reconciliation of reported results (GAAP) to operating results (Non-GAAP). "We are eager to move forward as Biogen Idec and to capitalize on our momentum. We are advancing toward completion of our proposed merger with IDEC in mid-November. Both companies are experiencing strong revenue growth and the merger integration planning is proceeding quickly and efficiently," said Jim Mullen, Biogen's Chairman and Chief Executive Officer. "In addition, our combined late-stage pipeline is progressing ahead: ANTEGREN(R) (natalizumab) is in Phase 3 trials in MS and Crohn's disease; RITUXAN(R) (rituximab) is in Phase 3 trials for Rheumatoid Arthritis; our partner, Fumapharm AG, has initiated a Phase 3 trial in Europe in psoriasis for the second-generation oral fumarate, and IDEC's anti-CD23 antibody will soon enter Phase 2 trials." NEUROLOGY AVONEX In August, the new pre-filled syringe for AVONEX, designed to make treatment even more convenient for people with MS, became available in the U.S. In Europe, the new prefilled syringe is being made available on a country-by-country basis. With more than 120,000 patients on therapy, AVONEX is the number one selling MS treatment worldwide. In the October 11th issue of The Lancet, researchers who conducted a five- year Danish study of 541 patients with relapsing-remitting multiple sclerosis concluded that patients who developed antibodies had a yearly relapse rate more than 50 percent higher than those who didn't produce antibodies. Throughout the study, AVONEX had a low rate of conversion from antibody negative to antibody positive. These new data provide additional insight into the potential relevance of neutralizing antibodies for MS patients. ANTEGREN Two Phase 3 studies of ANTEGREN in MS are underway. AFFIRM (natalizumab safety and efficacy in relapsing-remitting MS) will evaluate the ability of natalizumab to slow the rate of disability in MS and to reduce the rate of clinical relapses; SENTINEL (safety and efficacy of natalizumab in combination with AVONEX in patients with relapsing-remitting MS) will determine if the combination of natalizumab and AVONEX is more effective than treatment with AVONEX alone in slowing the rate of disability and reducing the rate of clinical relapses. The full trial results of ENACT-1 (Evaluation of Natalizumab in Active Crohn's disease Therapy-1) were presented on October 15th at the American College of Gastroenterology. In this Phase 3 induction trial, the primary endpoint of "response", as defined by a 70-point decrease in the Crohn's Disease Activity Index ("CDAI") at week 10, was not met. There were no notable differences in the overall rates of side effects between natalizumab and placebo treatment groups through week 12. The most common adverse events seen in the trial were headache, nausea, and abdominal pain across both groups. The natalizumab "maintenance" trial in Crohn's disease -- ENACT-2 (Evaluation of Natalizumab as Continuous Therapy-2) is ongoing. DERMATOLOGY AMEVIVE As of October, nearly 3,500 patients in the U.S. have initiated AMEVIVE treatment. More than 1,800 physicians in the U.S. are pursuing AMEVIVE therapy for their patients. The continued growth in referring physicians indicates expanding interest in the use of biologics for the treatment of psoriasis. Overall, the reimbursement environment for AMEVIVE continues to improve due to increased payor acceptance of AMEVIVE as well as the Company's efforts to broaden access options through specialty pharmacies. These factors are expected to improve physician and patient access to AMEVIVE. BG-12 (oral fumarate) Biogen has licensed from Fumapharm AG exclusive rights to develop and market a potential new oral therapy for psoriasis entering Phase 3 clinical trials in Europe. The product is a second-generation fumarate derivative with an immunomodulatory mechanism of action. A first-generation product is currently marketed as FUMADERM(R) in Germany, where it is the most prescribed oral systemic treatment of moderate-to-severe psoriasis. Fumapharm has completed a Phase 2 clinical trial of the second-generation product in psoriasis. Results of this double blind, multi-center study will be announced at an upcoming dermatology conference. Biogen plans to collaborate with Fumapharm to accelerate the Phase 3 clinical development and registration program worldwide. 2003 FINANCIAL GUIDANCE The Company confirmed that there is no change to its full year 2003 operating earnings per share guidance. Guidance for full year 2003 reported earnings per share (GAAP-based financial measure) is not currently assessable as the Company cannot predict with any certainty the nature or the amount of non-operating or unusual charges in the fourth quarter. CONFERENCE CALL AND WEBCAST The Company's earnings conference call for the third quarter will be broadcast via the Internet at 8:30 a.m. ET on October 28, 2003, and will be accessible through the investor relations section of Biogen's homepage, http://www.biogen.com/.

ABOUT AVONEX AVONEX (Interferon beta-1a) is used to treat relapsing forms of MS to slow the accumulation of physical disability and decrease the frequency of clinical exacerbations. The most common side effects associated with AVONEX treatment are flu-like symptoms including myalgia, fever, fatigue, headache, chills nausea, vomiting, pain and asthenia. AVONEX should be used with caution in patients with depression or other mood disorders and in patients with seizure disorders. AVONEX should not be used by pregnant women. Patients with cardiac disease should be closely monitored. Patients should also be monitored for signs of hepatic injury. Routine periodic blood chemistry and hematology tests are recommended during treatment with AVONEX. Rare cases of anaphylaxis have been reported.
