First MS Patients in the U.S. Receive Genzymes Lemtrada Following FDA Approval

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme, a Sanofi company, today announced that the first U.S. patients have initiated treatment with Lemtrada (alemtuzumab) in the commercial setting following its November 14th FDA approval for the treatment of patients with relapsing forms of multiple sclerosis (MS). Because of its safety profile, the use of Lemtrada should generally be reserved for patients who have had an inadequate response to two or more drugs indicated for the treatment of MS.

As an investigator in the Phase III clinical development program with firsthand experience, I have been awaiting the ability to prescribe Lemtrada to patients in my practice who could potentially benefit from this treatment, said Christopher LaGanke, M.D., founder of North Central Neurology Associates in Cullman, Ala. Following REMS training and certification, I am excited that I was able to become the first physician to initiate patient treatment in the United States.

Lemtrada has a unique 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.

The FDA approval of Lemtrada was based on two pivotal randomized Phase III open-label rater-blinded studies comparing treatment with Lemtrada to Rebif (high-dose subcutaneous interferon beta-1a) in patients with relapsing remitting MS who were either new to treatment (CARE-MS I) or who had relapsed while on prior therapy (CARE-MS II).

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. The clinical development program for Lemtrada involved nearly 1,500 patients with more than 6,400 patient-years of safety follow-up.

Since approval, we have been singularly focused on providing access as quickly as possible for those patients awaiting Lemtrada by ensuring drug availability, completing required REMS training and certifications, and establishing appropriate patient support, said Bill Sibold, Head of Genzymes Multiple Sclerosis business.

The Lemtrada label includes a boxed warning noting a risk of serious, sometimes fatal autoimmune conditions, serious and life-threatening infusion reactions and also noting Lemtrada may cause an increased risk of malignancies including thyroid cancer, melanoma and lymphoproliferative disorders.

The most common side effects of Lemtrada are rash, headache, pyrexia, nasopharyngitis, nausea, urinary tract infection, fatigue, insomnia, upper respiratory tract infection, herpes viral infection, urticaria, pruritus, thyroid gland disorders, fungal infection, arthralgia, pain in extremity, back pain, diarrhea, sinusitis, oropharyngeal pain, paresthesia, dizziness, abdominal pain, flushing, and vomiting. Other serious side effects associated with Lemtrada include autoimmune thyroid disease, autoimmune cytopenias, infections and pneumonitis.

Lemtrada is only available through a restricted distribution program, the Lemtrada REMS (Risk Evaluation and Mitigation Strategy). This program has been developed to ensure that access to Lemtrada in the U.S. is only through certified prescribers, healthcare facilities and pharmacies and to also ensure that patients are enrolled in the REMS program. The program is intended to help educate healthcare providers and patients on the serious risks associated with Lemtrada and the appropriate periodic monitoring required to support the detection of these risks for 48 months after the last infusion. The REMS is based on a developmental risk management program that was successfully implemented in the Phase 2 and Phase 3 trials and allowed for early detection and management of some of the serious risks associated with Lemtrada.

As part of its continued commitment to MS patients, Genzymes MS One to One program will provide information about multiple sclerosis, Lemtrada and other relevant resources. MS One to One is available and staffed by dedicated MS nurses and highly trained representatives who can provide support for individuals living with MS, their health care providers, family and loved ones. For more information about these support services, call the MS One to One line at 1-855-MSOne2One (1-855-676-6326) Monday through Friday, from 8:30am 8:00pm ET.
