Serono, Inc. (SRA) Announces FDA Approval Of Rebif(R) Titration Pack 
10/19/2005 5:12:30 PM

ROCKLAND, Mass., Dec. 20 /PRNewswire-FirstCall/ -- Serono, Inc. (virt-x: SEO and NYSE: SRA) announced today that the U.S. Food and Drug Administration (FDA) has approved a new Titration Pack for people who take Rebif(R) (interferon beta-1a) to treat relapsing forms of multiple sclerosis (MS).

The new Titration Pack is designed to provide improved convenience, ease of use and dosing accuracy for people beginning Rebif therapy, as they increase to the full dose during their first month of therapy. The new pack includes one month's supply of Rebif therapy, including a two-week supply of 8.8 mcg and a two-week supply of 22 mcg, both in pre-filled syringes. Rebif is the only therapy currently available in a titration pack.

Rebif is taken by injection to delay the progression of disability associated with relapsing forms of MS. It is the only approved MS therapy proven in a four-year clinical study in all three key measures of treatment effectiveness: reducing MRI lesion area and activity(1), reducing relapses and delaying the progression of disability. Also, the EVIDENCE trial demonstrated that Rebif 44 mcg, taken three times weekly, is superior to Avonex, another MS therapy, in reducing relapses over 48 weeks.

"We are excited about this latest addition to our portfolio of offerings for people living with MS," said James Pusey, M.D., executive vice president of Neurology at Serono, Inc. "Our mission is to make it as easy as possible to start-and stay on-MS therapy for improved outcomes over the long-term. The Titration Pack further demonstrates our commitment to that mission."

The Titration Pack is the latest offering by Serono in an ongoing commitment to improving the lives of people with MS. The company recently launched the MS LifeLines(TM) Nurses Educators program, providing qualified MS nurses to help educate newly diagnosed MS patients about therapy with Rebif. They also launched the new Rebiject II injection device and 29-gauge needle- the thinnest needle available for any MS therapy-designed to provide improvements in the ease of injections with Rebif. A survey of Rebif patients found that 83 percent preferred the Rebiject II to the original Rebiject device, and 96 percent preferred the new 29-gauge needle to the 27-gauge needle.

The newly approved Titration Pack will be available in the U.S. in early 2005. Patients can learn more about the titration pack and other product offerings by talking with their physician, calling MS LifeLines toll-free at 1-877-447-3243 or visiting http://www.mslifelines.com/.

About the Rebiject II and 29-Gauge Needle Survey

To identify preferences for Rebiject or Rebiject II, a telephone survey was conducted among 59 respondents who had experience using both devices. A similar survey was conducted among 26 patients comparing the 29-gauge and 27- gauge needles. Patients were unaware of the change in needle gauge. Patient responses for both surveys were based on self-assessments after two or more weeks of using the new device and/or needle.

About MS

MS is a chronic, inflammatory condition of the nervous system and is the most common, non-traumatic, neurological disease in young adults. MS may affect approximately two million people worldwide. While symptoms can vary, the most common symptoms of MS include blurred vision, numbness or tingling in the limbs and problems with strength and coordination. The relapsing forms of MS are the most common.

About MS LifeLines

MS LifeLines is an educational support service for the MS community provided by Serono and Pfizer. Its mission is to offer support to people with MS, people on or considering Rebif(R) therapy, and the care partners who support them.

About Rebif

Rebif (interferon beta-1a) is a disease-modifying drug (DMD) used to treat relapsing forms of MS to decrease relapses and delay the accumulation of physical disability, and is similar to the interferon beta protein produced by the human body. Interferon beta helps modulate the body's immune system, fight disease and reduce inflammation.

Rebif should be used with caution in patients with a history of depression, seizures or liver problems. Most commonly reported side effects are injection site disorders, flu-like symptoms, elevation of liver enzymes and blood cell abnormalities. Rebif is available in a 22 mcg and 44 mcg ready-to-use pre-filled syringe and can be stored at room temperature for up to 30 days if a refrigerator is not available. Patients should be instructed to read the Medication Guide accompanying the product.

Rebif(R), which was approved in Europe in 1998 and in the US in 2002, is registered in more than 80 countries worldwide. In the United States, Rebif is co-marketed by Serono, Inc. and Pfizer Inc.
