Positive Phase III Results of Genentech’s Investigational Medicine OCREVUS(TM) (Ocrelizumab) Published in New England Journal of MedicineSOUTH SAN FRANCISCO, Calif.--(Healthcare Sales & Marketing Network)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY) announced today that data from three Phase III studies of its investigational medicine OCREVUS™ (ocrelizumab) – the OPERA I and OPERA II studies in relapsing multiple sclerosis (RMS) and the ORATORIO study in primary progressive multiple sclerosis (PPMS) – were published in the December 21, 2016 online issue of the New England Journal of Medicine (NEJM).
Data from the OCREVUS Phase III studies showed consistent and clinically meaningful reductions in major markers of disease activity and progression compared with Rebif® (interferon beta-1a) in RMS and with placebo in PPMS. The primary endpoint was met in all three studies, which includes relative reduction of annualized relapse rate in the RMS studies and relative reduction in the progression of clinical disability sustained for at least 12 weeks in the PPMS study. Key secondary endpoints in all three studies were also met, including multiple measures of disability progression and brain lesion activity.
“These publications that indicate that B cells play a central role in MS are the result of a longstanding collaboration between the scientific community and industry for the benefit of people with MS,” said Stephen Hauser, M.D., Chair of the Scientific Steering Committee of the OPERA studies, Director of the Weill Institute for Neurosciences and Chair of the Department of Neurology at the University of California, San Francisco. “In the OPERA I and OPERA II RMS studies, OCREVUS consistently and significantly reduced disease activity and disability progression compared with a standard-of-care high-dose interferon while demonstrating a favorable safety profile. The consistency of these pioneering data, the effect seen in these clinical studies and the favorable safety profile may support treating MS earlier with a high-efficacy disease-modifying medicine.”
Data from two identical studies (OPERA I and OPERA II) in RMS showed OCREVUS was superior to high-dose Rebif (interferon beta-1a), a well-established MS therapy, in reducing three major markers of disease activity: relapses (primary endpoint), disability progression and brain lesion activity over the two-year controlled treatment period.
In a separate PPMS study (ORATORIO), OCREVUS significantly reduced the risk of confirmed disability progression sustained for at least 12 weeks (primary endpoint) and 24 weeks (a key secondary endpoint) compared with placebo. OCREVUS treatment was also superior to placebo on other key measures of disease progression in PPMS patients including the time required to walk 25 feet, the volume of chronic brain lesions and brain volume loss.
“OCREVUS is the first and only investigational medicine to significantly reduce the progression of physical disability in primary progressive MS in a large Phase III study,” said 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, Research Institute and Cemcat, Barcelona, Spain. “Over the last decade, other molecules have tried and failed to demonstrate efficacy for PPMS, so the positive results for OCREVUS mark an important step in our understanding of this highly disabling form of the disease.”
The OCREVUS safety profile was evaluated in the three Phase III studies. In the RMS studies, the proportion of patients with serious adverse events and serious infections was similar between the OCREVUS and interferon beta-1a treatment groups. In the PPMS study, the proportion of patients with adverse events and serious adverse events was similar between the OCREVUS and placebo treatment groups. Safety analyses continue in the open-label extension studies in both RMS and PPMS.
Marketing applications for OCREVUS, submitted for RMS and PPMS, have been accepted and are currently under review by the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA). As previously announced, OCREVUS was granted Priority Review Designation by the FDA with a targeted action date of March 28, 2017.
OCREVUS™ is the proprietary name submitted to the FDA for the investigational medicine ocrelizumab.
About the OPERA I and OPERA II studies in RMS
OPERA I and OPERA II are Phase III, randomized, double-blind, double-dummy, global multi-center studies evaluating the efficacy and safety of OCREVUS (600 mg administered by intravenous infusion every six months) compared with interferon beta-1a (44 mcg administered by subcutaneous injection three times per week) in 1,656 people with relapsing forms of MS. In these studies, relapsing MS (RMS) was defined as relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) with relapses. The primary and key secondary endpoints were previously presented at the 2015 congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
Data from the Phase III OPERA studies in patients with RMS showed:
- A 46 percent and 47 percent relative reduction in the annualized relapse rate (ARR) compared with interferon beta-1a over the two-year period in OPERA I and OPERA II, respectively (p<0.001 and p<0.001).
- A 43 percent and 37 percent relative risk reduction in confirmed disability progress (CDP) sustained for 12 weeks compared with interferon beta-1a in OPERA I and OPERA II, respectively, as measured by the Expanded Disability Status Scale (EDSS) (p=0.01 and p=0.02).
- A 43 percent and 37 percent relative risk reduction in CDP sustained for 24 weeks compared with interferon beta-1a in OPERA I and OPERA II, respectively (p=0.03 and p=0.04).
- A 94 percent and 95 percent relative reduction in the total number of T1 gadolinium-enhancing lesions compared with interferon beta-1a in OPERA I and OPERA II, respectively (p<0.001 and p<0.001).
- A 77 percent and 83 percent relative reduction in the total number of new and/or enlarging hyperintense T2 lesions compared with interferon beta-1a in OPERA I and OPERA II, respectively (p<0.001 and p<0.001).
Overall, the proportion of patients in the OCREVUS group with adverse events was similar to interferon beta-1a in both studies (80.1 percent in the OCREVUS group vs. 80.9 percent in the interferon beta-1a group in OPERA I and 86.3 percent in the OCREVUS group vs. 85.6 percent in the interferon beta-1a group in OPERA II); the most common adverse event associated with OCREVUS was infusion-related reactions (34.3 percent of patients who received OCREVUS experienced at least one infusion-related reaction vs. 9.9 percent for interferon beta-1a). The proportion of patients in the OCREVUS group with serious adverse events, including serious infections, was also similar to interferon beta-1a (6.9 percent in the OCREVUS group vs. 7.8 percent in the interferon beta-1a group in OPERA I and 7.0 percent in the OCREVUS group vs. 9.6 percent in the interferon beta-1a group in OPERA II).
About the ORATORIO study in PPMS
ORATORIO is a Phase III, randomized, double-blind, global multi-center study evaluating the efficacy and safety of OCREVUS (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. In contrast to the OPERA I and OPERA II studies, where the blinded treatment period was two years, the blinded treatment period of the ORATORIO study continued beyond that until all patients had received at least 120 weeks of either OCREVUS or placebo and a predefined number of confirmed disability progression (CDP) events was reached overall in the study. The primary and key secondary endpoints were previously presented at the 2015 congress of ECTRIMS.
Data from the Phase III ORATORIO study in patients with PPMS showed:
- A 24 percent relative risk reduction in CDP sustained for at least 12 weeks compared with placebo, as measured by the EDSS (p=0.03).
- A 25 percent relative risk reduction in CDP sustained for at least 24 weeks compared with placebo (p=0.04).
- A 29 percent relative reduction in the time required to walk 25 feet (Timed 25-Foot Walk) compared with placebo over 120 weeks (p=0.04).
- A 3.4 percent reduction in the total volume of brain hyperintense T2 lesions compared with a 7.4 percent increase in placebo-treated patients over 120 weeks (p<0.001).
- A 17.5 percent relative reduction in the rate of whole brain volume loss compared with placebo from week 24 to week 120 (p=0.02).
About OCREVUS™ (ocrelizumab)
OCREVUS is an investigational, humanized monoclonal antibody designed to selectively target CD20-positive B cells, a specific type of immune cell thought to be a key contributor to myelin (nerve cell insulation and support) and axonal (nerve cell) damage. This nerve cell damage can lead to disability in people with MS. Based on preclinical studies, OCREVUS binds to CD20 cell surface proteins expressed on certain B cells, but not on stem cells or plasma cells, and therefore important functions of the immune system may be preserved.
About multiple sclerosis
Multiple sclerosis (MS) is a chronic disease that affects an estimated 400,000 people in the U.S., for which there is currently no cure. MS occurs when the immune system abnormally attacks the insulation and support around nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage. This damage can cause a wide range of symptoms, including muscle weakness, fatigue and difficulty seeing, and may eventually lead to disability. 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.
Approximately 95 percent of people with MS have a relapsing form or primary progressive MS at diagnosis. Relapsing-remitting MS (RRMS) is the most common form of the disease and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. Over time, some people with RRMS experience steadily worsening symptoms and transition to secondary progressive MS (SPMS), with or without relapses. 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 or periods of remission. Approximately 10-15 percent of people with MS are diagnosed with the primary progressive form of the disease. There are no approved treatments for PPMS.
