Merck, a leading science and technology company, today announced enrolment has been completed in the Phase III EVOLUTION RMS clinical trial programme, 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 37^th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), taking place virtually from 13-15 October 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 enrolment in our evobrutinib Phase III EVOLUTION RMS clinical trial programme, 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. “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 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
• 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 annualised 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
• Safety profile characterisation 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^® is a short-course oral therapy that selectively and periodically targets lymphocytes thought to be integral to the pathological process of relapsing MS (RMS). In August 2017, the European Commission (EC) granted marketing authorization for MAVENCLAD^® for the treatment of relapsing forms of multiple sclerosis (RMS) in the 28 countries of the European Union (EU) in addition to Norway, Liechtenstein and Iceland. MAVENCLAD^® has since then been approved in over 80 countries, including Canada, Australia and the U.S. Refer to the respective prescribing information for further details.

The clinical development programme for cladribine tablets includes:

• The CLARITY (Cladribine Tablets Treating MS Orally) study: a two-year Phase III placebo-controlled study designed to evaluate the efficacy and safety of cladribine tablets as a monotherapy in patients with RRMS.
• The CLARITY extension study: a Phase III placebo-controlled study following on from the CLARITY study, which evaluated the safety and exploratory efficacy of cladribine tablets over two additional years beyond the two-year CLARITY study, according to the treatment assignment scheme for years 3 and 4.
• The ORACLE MS (Oral Cladribine in Early MS) study: a two-year Phase III placebo-controlled study designed to evaluate the efficacy and safety of cladribine tablets as a monotherapy in patients at risk of developing MS (patients who have experienced a first clinical event suggestive of MS).
• The ONWARD (Oral Cladribine Added ON to Interferon beta-1a in Patients With Active Relapsing Disease) study: a Phase II placebo-controlled study designed primarily to evaluate the safety and tolerability of adding cladribine tablets treatment to patients with relapsing forms of MS, who have experienced breakthrough disease while on established interferon-beta therapy.
• PREMIERE (Prospective Observational Long-term Safety Registry of Multiple Sclerosis) study: a long-term observational follow-up safety registry of MS patients who participated in cladribine tablets clinical studies.

In the two-year CLARITY study, the most commonly reported adverse event (AE) in patients treated with cladribine tablets was lymphopenia (26.7% with cladribine tablets and 1.8% for placebo). The incidence of infections was 48.3% with cladribine tablets and 42.5% with placebo, with 99.1% and 99.0% respectively rated mild-to-moderate by investigators. Adverse Events reported in other clinical studies were similar.

About Rebif^®

Rebif^® (interferon beta-1a) is a disease-modifying drug used to treat relapsing forms of multiple sclerosis (MS) and is similar to the interferon beta protein produced by the human body. The efficacy of Rebif^® in chronic progressive MS has not been established. Interferon ß is thought to help reduce inflammation. The exact mechanism is unknown.

Rebif^® , which was approved in Europe in 1998 and in the US in 2002, is registered in more than 90 countries worldwide. Rebif^® has been proven to delay the progression of disability, reduce the frequency of relapses and reduce MRI lesion activity and area*.

Rebif^® can be administered with the RebiSmart^® electronic auto-injection device (not approved in the US), or with the RebiDose^® single-use disposable pen, or the manual multidose injection pen RebiSlide™. Rebif^® can also be administered with the autoinjector Rebiject II^® or by manual injection using ready-to-use pre-filled syringes. These injection devices are not approved in all countries.

In January 2012, the European commission approved the extension of the indication of Rebif^® in early multiple sclerosis. The extension of the indication of Rebif^® has not been submitted in the United States.

Rebif^® should be used with caution in patients with a history of depression, liver disease, thyroid abnormalities and seizures. Most commonly reported side effects are flu-like symptoms, injection site disorders, elevation of liver enzymes and blood cell abnormalities. Patients, especially those with depression, seizure disorders, or liver problems, should discuss treatment with Rebif^® with their doctors.

*The exact correlation between MRI findings and the current or future clinical status of patients, including disability progression, is unknown.

Rebif^® (interferon beta-1a) is approved in the United States for relapsing forms of MS.

About Evobrutinib

Evobrutinib (M2951) is in clinical development to investigate its potential as a treatment for multiple sclerosis (MS). It is an oral, highly selective inhibitor of Bruton’s tyrosine kinase (BTK) which is important in the development and functioning of various immune cells including B lymphocytes and macrophages. Evobrutinib is designed to inhibit primary B cell responses such as proliferation and antibody and cytokine release, without directly affecting T cells. Evobrutinib is currently under clinical investigation and not approved for any use anywhere in the world.

About Multiple Sclerosis

Multiple sclerosis (MS) is a chronic, inflammatory condition of the central nervous system and is the most common non-traumatic, disabling neurological disease in young adults. It is estimated that approximately 2.8 million people have MS worldwide. While symptoms can vary, the most common symptoms of MS include blurred vision, numbness or tingling in the limbs and problems with strength and coordination. The relapsing forms of MS are the most common.

Merck in Neurology and Immunology

Merck has a long-standing legacy in neurology and immunology, with significant R&D and commercial experience in multiple sclerosis (MS). The company`s current MS portfolio includes two products for the treatment of relapsing MS – Rebif<sup>®</sup> (interferon beta-1a) and MAVENCLAD<sup>®</sup> (cladribine tablets).
