Genmab Announces European Marketing Authorization for Kesimpta^® (ofatumumab) in Relapsing Multiple Sclerosis

​

Company Announcement

​

​

Copenhagen, Denmark; March 30, 2021 – Genmab A/S (Nasdaq: GMAB) announced today that the European Commission (EC) has granted Novartis marketing authorization for the use of Kesimpta^® (ofatumumab) in the treatment of relapsing forms of multiple sclerosis (RMS) in adults with active disease defined by clinical or imaging features. The EC approval follows a positive opinion issued for subcutaneous ofatumumab in RMS by the CHMP of the European Medicines Agency (EMA) in January 2021. Kesimpta, which is developed and marketed worldwide by Novartis under a license agreement between Genmab and Novartis Pharma AG, is the first B-cell therapy that can be self-administered once-monthly at home via the Sensoready^® autoinjector pen.

​

“We are extremely pleased that Kesimpta is now approved in both Europe and in the U.S., providing RMS patients with a convenient, efficacious and safe treatment option as demonstrated in the study findings from the ASCLEPIOS trials. We are looking forward to the launch of Kesimpta in the various European markets,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

​

The approval was based on data from the Phase 3 ASCLEPIOS I and II trials, which investigated the efficacy and safety of monthly subcutaneous ofatumumab 20mg versus once daily oral teriflunomide 14mg in adults with RMS. The results from the ASCLEPIOS studies were published in the August 6, 2020 issue of The New England Journal of Medicine.

​

About ASCLEPIOS

The ASCLEPIOS I and II studies (NCT02792218 and NCT02792231) are twin, identical design, flexible duration (up to 30 months), double-blind, randomized, multi-center Phase 3 studies evaluating the safety and efficacy of ofatumumab 20mg monthly subcutaneous injections versus teriflunomide 14mg oral tablets taken once daily in adults with a confirmed diagnosis of RMS^1,2. The studies enrolled 1,882 patients with RMS, between the ages of 18 and 55 years, with an Expanded Disability Status Scale (EDSS) score between 0 and 5.5^1,2. The studies were conducted in over 350 sites in 37 countries.

​

The primary endpoint of both studies was to demonstrate that ofatumumab is superior to teriflunomide in reducing the frequency of confirmed relapses as evaluated by the annualized relapse rate (ARR) in patients treated up to 30 months^1,2. Secondary endpoints included time to disability progression confirmed at three and six months respectively, confirmed disability improvement at six months, gadolinium enhancing T1 lesions, number of new or enlarging T2 lesions, serum levels of neurofilament light chain (NfL), and rate of brain volume loss^1,2. Safety and the pharmacokinetic properties of ofatumumab were also all measured throughout the treatment period^1,2.

​

About Kesimpta^® (ofatumumab)

Ofatumumab is a fully human CD20 monoclonal antibody. It is self-administered by a once-monthly injection, delivered subcutaneously. Initial doses of Kesimpta are given at Weeks 0, 1 and 2, with the first injection performed under the guidance of a healthcare provider. It is approved in the U.S. for the treatment of RMS, to include clinically isolated

syndrome, relapsing-remitting disease, and active secondary progressive disease in adults. In Europe Kesimpta is approved for the treatment of RMS in adults with active disease defined by clinical or imaging features. Kesimpta is the first B-cell therapy that can be self-administered at home by patients using a Sensoready^® pen. Ofatumumab works by binding to the CD20 molecule on the B-cell surface and inducing potent B-cell lysis and depletion³. Ofatumumab is being developed and marketed worldwide by Novartis under a license agreement between Genmab and Novartis Pharma AG.

About Multiple Sclerosis

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system characterized by myelin destruction and axonal damage of the brain, optic nerves and spinal cord⁴. MS disrupts the normal functioning of the brain, optic nerves and spinal cord through inflammation and tissue loss⁵. MS affects approximately 2.8 million people worldwide⁶. Prevalence of MS is higher in the European and Americas regions, with a prevalence of 133 out of 10,000 people in Europe living with MS⁶. It is often characterized into the following forms: primary progressive MS (PPMS) and relapsing forms of MS (RMS), which includes relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS)⁷. Approximately 85% of patients initially present with RMS⁸.
