BERLIN, November 23 /PRNewswire-FirstCall/ -- Schering AG, Germany , majority-owned by the Bayer Group, announced today that the Australian Therapeutic Goods Administration has expanded the indication of Betaferon(R) (interferon beta-1b) to include patients with a first clinical event suggestive of multiple sclerosis (MS). This approval provides an important treatment option for patients in Australia to reduce the risk of developing clinically definite MS (CDMS), and thus creates the potential to delay the progression of the disease.
Earlier this year, Betaferon was granted marketing authorization in Europe, the United States and Canada for the treatment of patients with a first clinical event suggestive of multiple sclerosis.
"We are pleased that Betaferon is now available also for treatment of early MS in Australia where it is already the most prescribed MS treatment. With this approval, physicians and patients have a trusted treatment option for the early stages of the disease, when it has the greatest impact," said Dr. Darlene Jody, Head of Specialized Therapeutics at Schering Group."
The label extension is based on results from the BENEFIT[a] study which showed that Betaferon 250 mcg treatment in the early phase of the disease reduced the risk of developing CDMS by 50 percent compared with placebo [1,b]. Furthermore, patients in the Betaferon group were two times better protected[c] than placebo-treated patients against developing MS as defined by the McDonald diagnostic criteria. Betaferon was also very well accepted in the BENEFIT study, with 93 percent of patients completing the two-year study period.

The multi-center, double-blind, randomized, phase III BENEFIT study was conducted in 98 centers in 20 countries and included a total of 487 patients presenting with a single clinical episode suggestive of MS. Patients with a first clinical demyelinating event suggestive of MS and typical MRI findings received either eight million units of interferon beta-1b (Betaferon) every other day or placebo as a subcutaneous injection. Treatment continued for up to 24 months unless patients experienced a second attack and were diagnosed with clinically definite MS. The two co-primary efficacy outcomes were time to CDMS, based on a second clinical demyelinating event or an Expanded Disability Status Scale (EDSS) progression >=1.5 points, and time to MS according to the McDonald criteria. All study participants completing the double blind study were then invited to participate in a separate open-label follow-up study with Betaferon which will prospectively assess the impact of such early treatment with Betaferon on the long-term course of the disease for a total observation time of five years, including the impact of early treatment on the formation of new brain lesions as measured by magnetic resonance imaging (MRI).
BENEFIT patients included those who had a first clinical demyelinating event either monofocal (i.e. clinical evidence of a single lesion) or multifocal (i.e. clinical evidence of more than one lesion). Inclusion of both patient groups is important because this is representative for the patient population with a single event.
Betaferon/Betaseron was the first disease-modifying drug introduced for MS and is a well-established treatment around the world. Betaferon has the broadest experience of any MS medication. In the U.S., Europe and Japan, Betaferon has been approved for all relapsing forms of MS. It is able to reduce the number of MS episodes by one-third, and the frequency of moderate to severe episodes by as much as 50 percent. Sixteen years' follow up of people treated with Betaferon has shown that it is safe and well tolerated.
