Roche (SIX: RO, ROG; OTCQX: RHHBY) announced positive results from a pivotal Phase III study that evaluated an investigational medicine in people with primary progressive multiple sclerosis (PPMS). The study (called ORATORIO) met its primary endpoint, showing treatment with this medicine significantly reduced the progression of clinical disability sustained for at least 12 weeks compared with placebo, as measured by the Expanded Disability Status Scale (EDSS).
Overall, the incidence of adverse events associated with the investigational medicine was similar to placebo; the most common adverse events were mild-to-moderate infusion-related reactions. The incidence of serious adverse events associated with this investigational medicine, including serious infections, was also similar to placebo.
“People with the primary progressive form of MS typically experience symptoms that continuously worsen after the onset of their disease, and there are no approved treatments for this debilitating condition,” said Sandra Horning, M.D., Roche’s Chief Medical Officer and Head of Global Product Development. “This is the first investigational medicine to show a clinically meaningful and statistically significant effect on the progression of disease in primary progressive MS.”
The positive study results observed in both people with PPMS (ORATORIO) as well as those with relapsing forms of MS (OPERA I and OPERA II) validate the hypothesis that B cells are central to the underlying biology of the disease.
Top-line data from the ORATORIO study will be presented as a late-breaking abstract at the 31st congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) by Xavier Montalban, M.D., Ph.D., Chair of the Scientific Steering Committee of the ORATORIO study and Professor of Neurology and Neuroimmunology at Vall d’Hebron University Hospital and Research Institute, Barcelona, Spain, on Saturday, 10th October (Abstract #228, 8:52 – 9:03 CET) in Barcelona, Spain.
Additionally, Phase III results in people with relapsing MS (OPERA I and OPERA II studies) will be presented at ECTRIMS by Stephen Hauser, M.D., Chair of the Scientific Steering Committee of the OPERA studies and Chair of the Department of Neurology at the University of California San Francisco School of Medicine, on Friday, 9th October (Abstract #190, 14:40 – 14:52 CET).
Roche plans to pursue marketing authorisation for this new investigational medicine in relapsing MS and in PPMS. Data from the OPERA I and II studies and from the ORATORIO study will be submitted to global regulatory authorities in early 2016.
About the ORATORIO study
ORATORIO is a Phase III, randomised, double-blind, global multi-centre study evaluating the efficacy and safety of the investigational medicine (600 mg administered by intravenous infusion every six months; given as two 300 mg infusions two weeks apart) compared with placebo in 732 people with PPMS.[i] The primary endpoint of the ORATORIO study was time to onset of confirmed disability progression (CDP), defined as an increase in EDSS that is sustained for at least 12 weeks.
In addition to ORATORIO, the Phase III clinical development programme for this investigational medicine includes OPERA I and OPERA II, which are randomised, double-blind, double-dummy, global multi-centre studies in people with relapsing forms of MS.2,[ii]
About multiple sclerosis
Multiple sclerosis (MS) is a chronic disease that affects an estimated 2.3 million people around the world, for which there is currently no cure.[iii],[iv] MS occurs when the immune system abnormally attacks the insulation and support around the nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage.[v],[vi] Damage to these nerve cells can cause a wide range of symptoms, including muscle weakness, fatigue and difficulty seeing, and may eventually lead to disability.4 Most people with MS experience their first symptom between 20 and 40 years of age, making the disease the leading cause of non-traumatic disability in younger adults.[vii],[viii]
Relapsing MS is the most common form of the disease. Disease activity and progression can occur even when people do not show signs or symptoms of MS, despite available relapsing MS treatments. Primary progressive MS (PPMS) is a debilitating form of the disease marked by steadily worsening symptoms but typically without distinct relapses (periods of time when symptoms flare) or periods of remission.[ix] Approximately one in 10 people with MS are diagnosed with the primary progressive form of the disease. There are no approved treatments for PPMS.
