SUNNYVALE, CA, May 25, 2001 – Scios Inc. (Nasdaq: SCIO) announced today that the Cardiovascular and Renal Drugs Advisory Committee to the U.S. Food and Drug Administration (FDA) unanimously recommended approval of Natrecor^® (nesiritide) for the treatment of acute congestive heart failure (CHF) by a vote of 10-0.

If approved by the FDA, Natrecor would be the first new treatment for acute CHF in more than a decade. Natrecor is a recombinant form of B-type natriuretic peptide (BNP), a naturally occurring hormone in the body that aids healthy functioning of the heart. BNP causes arteries and veins to dilate, alleviating symptoms by improving blood movement around the heart without a change in heart rate. Natrecor is administered intravenously in a standard fixed dose regimen, and typically does not require titration (i.e., dose adjustments). Approximately five million Americans suffer from congestive heart failure, and there are approximately one million hospitalizations each year in the United States due to acute CHF.

“Natrecor is now one step closer to approval and helping physicians manage acute CHF patients, which are growing in number every year,” said Darlene P. Horton, M.D., Scios’ Vice President of Medical Affairs. “We commend the clinical investigators and their teams at leading medical centers around the country who made it possible to expedite high-quality clinical trials evaluating Natrecor. We are very proud of this dedicated development effort.”

Based on the outcome of clinical trials involving nearly 1,000 patients treated with Natrecor, Scios submitted an amendment to the New Drug Application (NDA) for Natrecor to the FDA in early 2001. The original NDA was filed with the FDA in April 1998. The FDA subsequently requested additional data on Natrecor, which was included in the amended application filed in January of 2001. Despite a positive Advisory Committee recommendation, the FDA’s final decision may differ. We expect the FDA to make its decision in July 2001.

In anticipation of final FDA approval of Natrecor, Scios entered into a commercialization and marketing agreement for Natrecor in the United States with Innovex, the commercialization unit of Quintiles Transnational Corp. (NASDAQ: QTRN).

“We are building a 180-person strong sales and marketing force that we believe will be the largest and the most focused in the U.S. acute CHF market,” said Richard B. Brewer, Scios’ President and Chief Executive Officer. “We have hired two area business directors who will coordinate and lead the field sales effort with the 18 business managers who will support the sales force. We will be ready to launch the product at the end of July if Natrecor is approved by the FDA.”

Clinical Trial Results

Presenters at today’s advisory committee meeting reviewed results of several clinical trials, including the pivotal 498-patient VMAC (Vasodilation in the Management of Acute Congestive heart failure) trial. The data demonstrated Natrecor’s ability to rapidly improve blood circulation and reduce pulmonary capillary wedge pressure (PCWP), a measure of the pulmonary congestion resulting from acute CHF, in as little as 15 minutes. This effect was sustained for at least 48 hours. Natrecor has also been shown to rapidly alleviate patient symptoms, such as shortness of breath and fatigue. The most common side effects have been headache, reversible hypotension, and abdominal pain.

In addition to Dr. Horton, data was also presented to the Advisory Committee by James B. Young, M.D., Head, Section of Heart Failure and Cardiac Transplant Medicine and Medical Director of the Kaufman Center for Heart Failure at the Cleveland Clinic Foundation, and William Abraham, M.D., Chief, Division of Cardiovascular Medicine and Director, Section of Heart Failure and Cardiac Transplantation, University of Kentucky College of Medicine.

Congestive Heart Failure – An Epidemic

A potentially life-threatening disorder that has no cure, heart failure is a chronic pathophysiologic condition in which the heart functions inefficiently and circulation is reduced to the body’s organs. In congestive heart failure, fluid accumulates in the tissues, including lung tissue, causing such symptoms as difficulty breathing, swelling of the hands and feet, difficulty sleeping, dry cough, fatigue and rapid weight gain. CHF may result from an acute event (e.g., heart attack) or may develop gradually over time.

During an acute episode of CHF, the heart’s inability to adequately circulate blood throughout the body worsens beyond its already compromised state, causing symptoms to become so pronounced that hospital treatment is required to stabilize the patient’s condition. A sudden increase in dietary sodium (salt), failure to take chronic oral medications for managing CHF, or the development of a new heart arrhythmia can precipitate an acute attack.
