GENEVA, October 15, 2010 /PRNewswire/ -- Merck Serono, a division of Merck KGaA, Darmstadt, Germany, announced today the upcoming introduction of the new device RebiDose(TM), the Rebif(R) single use pre-filled pen, for the self-administration of Rebif(R) (interferon beta-1a), a disease-modifying drug used to treat relapsing forms of multiple sclerosis (MS).
We are pleased to extend our range of devices with RebiDose(TM) to meet the needs of patients looking for simple and minimum injection preparation, said Roberto Gradnik, Head of Global Business Unit Neurodegenerative Diseases at Merck Serono. The introduction of RebiDose(TM), alongside RebiSmart(TM), which was launched last year, underscores our commitment to improve the treatment convenience of multiple sclerosis patients, by offering them different options to suit their individual injection needs.
RebiDose(TM) was specifically designed to provide MS patients with a quick and simple device. This pre-filled injection device may also be ideal for patients who are traveling. RebiDose(TM) used with Rebif(R) will be available in a monthly pack in two different doses (22 micrograms and 44 micrograms) and in a titration pack including two different doses (8.8 micrograms and 22 micrograms). RebiDose(TM) has been approved in the European Union and in Australia. It will be launched on a country-by-country basis, with first launches planned by the end of the year.
The results of the RebiDose(TM) user trial showed that the majority of patients found the device easy to use, reliable and convenient with a 0.4% error rate. 72% percent of study participants indicated that they would continue using RebiDose(TM) if it became available. The RebiDose(TM) user trial data were presented today at the 26th Congress of the European Committee for the Treatment and Research in Multiple Sclerosis (ECTRIMS) held in Gothenburg, Sweden, from October 13-16, 2010.
About the RebiDose(TM) user trial
The user trial was a 12-week, phase IIIb, multicenter, open-label, single-arm study to evaluate RebiDose(TM), for the self administration of Rebif(R) (interferon beta-1a) with respect to ease of use, patient satisfaction and acceptability, and functional reliability. Patients with relapsing MS, who were receiving Rebif(R) 44 microgram three times weekly for more than 12 weeks, continued MS therapy using RebiDose(TM) for 12 weeks.
A total of 109 patients were enrolled in the study. Patients were between 18 and 65 years old with relapsing MS (McDonald criteria) and had received Rebif(R), 44 microgram three times weekly, consistently for 12 weeks or more prior to screening. Patients completed a user trial questionnaire at baseline and weeks 6 and 12.
The primary endpoint was the proportion of patients rating Rebidose(TM) as easy or very easy to use at week 12. Secondary endpoints included ratings of functional reliability, simplicity of use, and convenience. QoL was assessed using the Short Form-36v2 General Health Survey at screening and week 12. Safety endpoints included the incidence of serious adverse events (AEs).
RebiDose(TM), has not been approved in the US.
Rebif(R) (interferon beta-1a) is a disease-modifying drug used to treat relapsing forms of multiple sclerosis (MS) and is similar to the interferon beta protein produced by the human body. The efficacy of Rebif(R) in chronic progressive MS has not been established. Interferons are thought to help modulate the body's immune system and reduce inflammation. The exact mechanism is unknown.
Rebif(R), which was approved in Europe in 1998 and in the US in 2002, is registered in more than 90 countries worldwide. Rebif(R) has been proven to delay the progression of disability, reduce the frequency of relapses and reduce MRI lesion activity and area*. Rebif(R) is available in a 22 micrograms and 44 micrograms ready-to-use pre-filled syringe and a titration pack (8.8 micrograms). Rebif(R) is also now available in two multidose cartridges [132 micrograms (three doses of 44 micrograms) and 66 micrograms (three doses of 22 micrograms)] for the use with the RebiSmart(TM) device, in several EU member countries, Switzerland and Canada, as well as in Australia.
Rebif(R) should be used with caution in patients with a history of depression, liver disease and seizures. Most commonly reported side effects are flu-like symptoms, injection site disorders, elevation of liver enzymes and blood cell abnormalities. Patients, especially those with depression, seizure disorders, or liver problems, should discuss treatment with Rebif(R) with their doctors.
* The exact correlation between MRI findings and the current or future clinical status of patients, including disability progression, is unknown.
About multiple sclerosis
Multiple sclerosis (MS) is a chronic, inflammatory condition of the central nervous system and is the most common, non-traumatic, disabling neurological disease in young adults. It is estimated that approximately two million people have MS 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.
