EMD Serono Completes Enrollment of Evobrutinib Phase III Clinical Trials Ahead of ECTRIMS 2021

  • Investigational evobrutinib is the first Bruton’s tyrosine kinase (BTK) inhibitor to complete Phase III clinical trial enrollment in relapsing multiple sclerosis (RMS)
  • Data from oral presentations at ECTRIMS show evobrutinib has a positive impact on important biomarkers of disease progression
  • New independent data being presented found that patients treated with MAVENCLAD® (cladribine) tablets had increased antibody IgG titer levels similar to that of the general population after a complete course of an mRNA COVID-19 vaccine

ROCKLAND, Mass.–(BUSINESS WIRE)–EMD Serono, the Healthcare business sector of Merck KGaA, Darmstadt, Germany, in the U.S. and Canada, today announced enrollment has been completed in the Phase III EVOLUTION RMS clinical trial program, which is evaluating the efficacy and safety of investigational Bruton’s tyrosine kinase (BTK) inhibitor evobrutinib in patients with relapsing multiple sclerosis (RMS). This milestone comes just ahead of the 37th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), taking place virtually from October 13-15, 2021, where 39 abstracts from the Company’s multiple sclerosis (MS) portfolio will be presented. Data will include two oral presentations and a late-breaking ePoster on evobrutinib as well as late-breaking ePosters on MAVENCLAD® (cladribine) tablets including new interim data on patient-reported improvements in quality of life (QoL) and new independent data on MAVENCLAD patients who have received a complete course of an mRNA COVID-19 vaccine.

“The breadth of our data at ECTRIMS, paired with the rapid enrollment in our evobrutinib Phase III EVOLUTION RMS clinical trial program, further exemplifies a commitment to continue breaking boundaries in the science of MS,” said Danny Bar-Zohar, Global Head of Development for the Healthcare business of Merck KGaA, Darmstadt, Germany. “By generating new data on MAVENCLAD to demonstrate the positive real-life impact it can have for people with RMS, and also on progressing evobrutinib with its dual mode of action targeting both B-cells and innate immune cells in the central nervous system and periphery, we are hoping to address the needs of people with RMS now and in the future.”

Key MAVENCLAD® (cladribine) tablets data include:

  • Updated post-approval safety data of MAVENCLAD demonstrating consistency of real-world experience with the profile reported in the Phase III and ongoing Phase IV trials, and providing evidence that patients receiving MAVENCLAD do not appear at increased risk of severe COVID-19 outcomes
  • In an independent open label study, patients treated with MAVENCLAD were found to increase antibody immunoglobulin G (IgG) titer levels similar to healthy controls after a complete course of an mRNA COVID-19 vaccine. In the U.S., the MAVENCLAD label states that all immunizations should be administered according to immunization guidelines prior to starting MAVENCLAD
  • A new interim analysis from the Phase IV CLARIFY-MS study demonstrating that patients living with RMS reported an improvement in physical and mental health at one year of MAVENCLAD treatment
  • Real-world MAVENCLAD data from the MSBase Registry demonstrating adherence to MAVENCLAD and an annualized relapse rate similar to clinical trial data
  • Late-breaking data including:

    • Long-term Efficacy for Patients Receiving Cladribine Tablets in CLARITY/CLARITY Extension: Primary Results from 9–15 Years of Follow-up in the CLASSIC-MS Study
    • Cladribine tablets after treatment with natalizumab (CLADRINA) trial – Interim analyses

Key evobrutinib data include:

  • Data from a post-hoc analysis in the Phase II trial with evobrutinib demonstrated a reduction in volume of slowly expanding lesions (SELs), an in-vivo magnetic resonance imaging (MRI) correlate of chronic active inflammation and axonal loss within the central nervous system (CNS), which may be predictive of subsequent clinical disease progression in MS
  • Results from the same trial showed that increased levels of blood neurofilament light chain (NfL), a marker of neuronal damage, at baseline were predictive of increased relapse and MRI lesion activity in the study and evobrutinib significantly reduced MRI and relapse outcomes
  • Extensive safety profile characterization of evobrutinib in over 1000 patients from Phase II clinical trials in MS, rheumatoid arthritis and systemic lupus erythematosus demonstrating that overall evobrutinib treatment (all doses) was generally well tolerated across indications and elevations in liver enzymes were asymptomatic and reversible

About MAVENCLAD®

MAVENCLAD, approved by the U.S. Food and Drug Administration (FDA) on March 29, 2019, is the first and only short-course oral therapy for the treatment of adults with relapsing-remitting disease (RRMS) and active secondary progressive disease (SPMS). Because of its safety profile, use of MAVENCLAD is generally recommended for patients who have had an inadequate response to, or are unable to tolerate, an alternate drug indicated for the treatment of multiple sclerosis (MS), and MAVENCLAD is not recommended for use in patients with clinically isolated syndrome (CIS). Patients should follow healthcare provider instructions including cancer screening, contraception and blood tests. The approved dose of MAVENCLAD is 3.5 mg per kg body weight over two years, administered as one treatment course of 1.75 mg per kg per year, each consisting of two treatment weeks. The mechanism by which cladribine exerts its therapeutic effects in patients with multiple sclerosis has not been fully elucidated but is thought to involve cytotoxic effects on B and T lymphocytes through impairment of DNA synthesis, resulting in depletion of lymphocytes. MAVENCLAD causes a dose-dependent reduction in lymphocyte counts followed by recovery.

Because cladribine is cytotoxic, special handling and disposal instructions should be followed.

MAVENCLAD has been approved in over 80 countries, including the European Union (EU), Canada, Australia and Switzerland, for various relapsing MS indications. Visit www.MAVENCLAD.com for more information.

IMPORTANT SAFETY INFORMATION

WARNING: MALIGNANCIES and RISK OF TERATOGENICITY

  • Treatment with MAVENCLAD may increase the risk of malignancy. MAVENCLAD is contraindicated in patients with current malignancy. In patients with prior malignancy or with increased risk of malignancy, evaluate the benefits and risks of the use of MAVENCLAD on an individual patient basis. Follow standard cancer screening guidelines in patients treated with MAVENCLAD
  • MAVENCLAD is contraindicated for use in pregnant women and in women and men of reproductive potential who do not plan to use effective contraception because of the potential for fetal harm. Malformations and embryolethality occurred in animals. Exclude pregnancy before the start of treatment with MAVENCLAD in females of reproductive potential. Advise females and males of reproductive potential to use effective contraception during MAVENCLAD dosing and for 6 months after the last dose in each treatment course. Stop MAVENCLAD if the patient becomes pregnant

CONTRAINDICATIONS

  • Patients with current malignancy.
  • Pregnant women, and women and men of reproductive potential who do not plan to use effective contraception during and for 6 months after the last dose in each treatment course. May cause fetal harm.
  • Patients with human immunodeficiency virus (HIV).
  • Patients with active chronic infections (e.g., hepatitis or tuberculosis).
  • Patients with a history of hypersensitivity to cladribine.
  • Women intending to breastfeed while taking MAVENCLAD tablets and for 10 days after the last dose.

WARNINGS AND PRECAUTIONS

  • Malignancies: Treatment with MAVENCLAD may increase the risk of malignancy. After the completion of 2 treatment courses, do not administer additional MAVENCLAD treatment during the next 2 years. In clinical studies, patients who received additional MAVENCLAD treatment within 2 years after the first 2 treatment courses had an increased incidence of malignancy. The risk of malignancy with reinitiating MAVENCLAD more than 2 years after the completion of 2 treatment courses has not been studied. Follow standard cancer screening guidelines in patients treated with MAVENCLAD.
  • Risk of Teratogenicity: MAVENCLAD may cause fetal harm when administered to pregnant women. In females of reproductive potential, exclude pregnancy before initiation of each treatment course of MAVENCLAD and prevent by the use of effective contraception during MAVENCLAD dosing and for at least 6 months after the last dose of each treatment course. Women who become pregnant during treatment with MAVENCLAD should discontinue treatment.
  • Lymphopenia: MAVENCLAD causes a dose-dependent reduction in lymphocyte count. In clinical studies, 87% of MAVENCLAD-treated patients experienced lymphopenia. The lowest absolute lymphocyte counts occurred approximately 2 to 3 months after the start of each treatment course and were lower with each additional treatment course. Concomitant use of MAVENCLAD with hematotoxic drugs may increase the risk of adverse reactions because of the additive hematological effects. Monitor lymphocyte counts before and during treatment, periodically thereafter, and when clinically indicated.
  • Infections: MAVENCLAD can reduce the body’s immune defense and may increase the likelihood of infections. Infections occurred in 49% of MAVENCLAD-treated patients compared to 44% of patients treated with placebo in clinical studies. The most frequent serious infections included herpes zoster and pyelonephritis. Single fatal cases of tuberculosis and fulminant hepatitis B were reported in the clinical program. Administer live-attenuated or live vaccines at least 4 to 6 weeks prior to starting MAVENCLAD.
