– In approximately 70 percent of patients, disability scores improved or remained stable for an additional two years beyond the two-year pivotal multiple sclerosis studies –
– Approximately 70 percent of patients treated with Lemtrada did not receive a third course of treatment through the second year of the extension
CAMBRIDGE, MA, USA I September 11, 2014 I Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), announced today positive interim results from the second year of the extension study of Lemtrada™ (alemtuzumab) for multiple sclerosis.
In this analysis, relapse rates and sustained accumulation of disability remained low among patients who had previously received Lemtrada in either of the Phase III CARE-MS I and CARE-MS II studies. In these pivotal studies, Lemtrada was given as two annual courses, at the start of the study and 12 months later. Approximately 70 percent of patients who received Lemtrada in the pivotal studies did not receive further treatment with Lemtrada through the second year of the extension study. No new safety signals were identified. These data will be presented today at the European Committee for Research and Treatment in Multiple Sclerosis (ECTRIMS) meeting in Boston.
“These extension study results provide further evidence of the prolonged efficacy of Lemtrada on both relapses and disability,” said Dr. Alasdair Coles, Senior Lecturer, Department of Clinical Neurosciences, University of Cambridge. “The majority of patients continued to experience reduced disease activity, even though their last Lemtrada treatment was three years earlier.”
Extension Study Results
The Phase III trials of Lemtrada were randomized, two-year pivotal studies comparing treatment with Lemtrada to high-dose subcutaneous interferon beta-1a (Rebif®) in patients with relapsing-remitting multiple sclerosis who had active disease and were either new to treatment (CARE-MS I) or who had relapsed while on prior therapy (CARE-MS II).
More than 90 percent of the patients who were treated with Lemtrada in the Phase III trials enrolled in the extension study. These patients were eligible to receive additional treatment with Lemtrada in the extension study if they experienced at least one relapse or at least two new or enlarging brain or spinal cord lesions.
The following interim results are from the second year of the extension study for patients who previously received Lemtrada in the two-year pivotal studies:
- In year four, the annualized relapse rates for patients who received Lemtrada in CARE-MS I and CARE-MS II were 0.14 and 0.23, respectively. These rates were comparable to the annualized relapse rates for those patients who received Lemtrada in the pivotal trials.
- Through year four, 74 percent of patients in CARE-MS I and 66 percent in CARE-MS II had improved or stable disability as measured by the Expanded Disability Status Scale (EDSS).
- Through year four, 83 percent and 76 percent of patients who received Lemtrada in the pivotal trials, respectively, did not experience six-month sustained accumulation of disability – meaning they did not experience a worsening of their disability that persisted for six continuous months in the four years of observation.
- Approximately 70 percent of patients treated with Lemtrada in the pivotal studies did not receive a third course of treatment in years three and four.
“MS is a devastating disease and patients remain in need of new treatment options that may offer greater efficacy. These new data reinforce the transformative potential of Lemtrada,” said Genzyme President and CEO, David Meeker, M.D. “It is encouraging to see the durable efficacy and manageable safety of Lemtrada maintained two years into the extension study.”
Safety results from the second year of the extension study were reported. No new risks were identified. As previously reported, there were two deaths in the extension study. One was from sepsis and the other was presumed accidental and deemed unrelated to study treatment. Over four years, approximately 2 percent of patients treated with Lemtrada in the pivotal trials developed immune thrombocytopenia (ITP), all of whom responded to treatment. Patient monitoring for autoimmune disorders is incorporated in all Genzyme-sponsored trials of Lemtrada.
The most common side effects of Lemtrada are infusion associated reactions (headache, rash, pyrexia, nausea, fatigue, urticaria, insomnia, pruritus, diarrhea, chills, dizziness, and flushing), infections (upper respiratory tract and urinary tract), and thyroid disorders. Autoimmune conditions (including immune thrombocytopenia, other cytopenias, glomerulonephritis and thyroid disease) and serious infections can occur in patients receiving Lemtrada. A comprehensive risk management program incorporating education and monitoring will help support early detection and management of these identified risks.
About CARE-MS
The Lemtrada clinical development program included two randomized Phase III studies comparing treatment with Lemtrada to high-dose subcutaneous interferon beta-1a (Rebif®) in patients with RRMS who had active disease and were either new to treatment (CARE-MS I) or who had relapsed while on prior therapy (CARE-MS II), as well as an ongoing extension study. In CARE-MS I, Lemtrada was significantly more effective than interferon beta-1a at reducing annualized relapse rates; the difference observed in slowing disability progression did not reach statistical significance. In CARE-MS II, Lemtrada was significantly more effective than interferon beta-1a at reducing annualized relapse rates, and accumulation of disability was significantly slowed in patients given Lemtrada vs. interferon beta-1a.
About LemtradaTM (alemtuzumab)
Lemtrada is supported by a comprehensive and extensive clinical development program that involved nearly 1,500 patients and 5,400 patient-years of follow-up. Lemtrada 12 mg has a novel dosing and administration schedule of two annual treatment courses. The first treatment course is administered via intravenous infusion on five consecutive days, and the second course is administered on three consecutive days, 12 months later.
Lemtrada is approved in the European Union, Australia, Canada, Mexico, Brazil, Argentina, Chile and Guatemala. Lemtrada is currently not approved in the United States. The U.S. Food and Drug Administration (FDA) has accepted for review the company’s resubmission of its application seeking approval of Lemtrada, and Genzyme expects FDA action on the application in the fourth quarter. Marketing applications for Lemtrada are also under review in other countries.
Alemtuzumab is a monoclonal antibody that selectively targets CD52, a protein abundant on T and B cells. Treatment with alemtuzumab results in the depletion of circulating T and B cells thought to be responsible for the damaging inflammatory process in MS. Alemtuzumab has minimal impact on other immune cells. The acute anti-inflammatory effect of alemtuzumab is immediately followed by the onset of a distinctive pattern of T and B cell repopulation that continues over time, rebalancing the immune system in a way that potentially reduces MS disease activity.
Genzyme holds the worldwide rights to alemtuzumab and has primary responsibility for its development and commercialization in multiple sclerosis. Bayer HealthCare holds the right to co-promote alemtuzumab in MS in the United States. Upon commercialization, Bayer will receive contingent payments based on global sales revenue.
