Data Provide Insight into the Mode of Action of MAVENCLAD™ (Cladribine Tablets) in Patients with Relapsing MS

Data suggest that MAVENCLAD™ (Cladribine Tablets) selectively and discontinuously reduces B and T lymphocytes, with lymphocyte counts returning to normal range before the end of Year 2 

The lymphocyte data presented at EAN Congress are consistent with other clinical safety presentations of MAVENCLAD™ (Cladribine Tablets) at the congress 

Merck announced the presentation of safety and efficacy data on MAVENCLAD™ (Cladribine Tablets) for the treatment of relapsing MS at the 3rd Congress of the European Association of Neurology (EAN), in Amsterdam, the Netherlands.

Data from the placebo-controlled CLARITY, CLARITY Extension and ORACLE-MS clinical trials support the benefit:risk profile of Cladribine Tablets that have prompted an application for marketing authorisation in the EU, and the recent positive opinion from the Committee for Medicinal Products for Human Use (CHMP).

In these studies, Cladribine Tablets was administered as two annual treatment courses in Years 1 and 2, with a total maximum of 20 days of oral treatment equal to a dose of 3.5 mg/kg body weight, followed by no further active treatment in Years 3 and 4.

“These data presented at EAN Congress 2017 bring the MS treating community closer to understanding the mechanism of action of Cladribine Tablets,” said Professor Per Soelberg Sørensen, presenting author and Head of MS Research Unit, Danish Multiple Sclerosis Centre. “These data support the emerging theories around the ability of some agents to selectively ‘reset’ the immune system without the secondary autoimmunity that we sometimes see with treatments for relapsing MS. This would represent a significant advance in the field.”

About MAVENCLAD™ (Cladribine Tablets) 

Cladribine Tablets is a short-course oral therapy that is believed to selectively and periodically target lymphocytes thought to be integral to the pathological process of MS. Cladribine Tablets is currently under clinical investigation and not yet approved for the treatment for any use in the United States, Canada and Europe. On 23 June, the Committee for Medicinal Products for Human Use (CHMP) granted a positive opinion on the use of Cladribine Tablets for highly active relapsing MS, and this recommendation has been passed on to the EC to make the final decision on the Marketing Authorization Application (MAA) later this year.

The clinical development program 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 MAVENCLAD as a monotherapy in patients with RRMS.
  •  The CLARITY extension study: a four-year Phase III placebo-controlled study following on from the CLARITY study, designed to evaluate the safety and efficacy of MAVENCLAD over an extended administration for four years.
  •  CLARITY (CLAdRIbine Tablets Treating MS OrallY) study and its extension: 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 and its two-year extension designed to provide data on the long-term safety and efficacy of extended administration of Cladribine Tablets for up to four years.
  •  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).
  •  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 Patients Who Have Participated in Cladribine Clinical Studies) study: interim long-term follow-up data from the prospective registry, PREMIERE, to evaluate the safety and efficacy of Cladribine Tablets. The follow-up will consist of over 10,000 patient years of exposure in total, with follow-up in some patients exceeding eight years at completion.

Epilepsy: innovative substances and interventions – Guillain-Barré syndrome: risk influenced by month of birth – New antibody helps migraine patients who overuse medication

Epilepsy: innovative substances and interventions fly in the face of therapy resistance
Numerous new medicines now deliver effective help for epilepsy patients. However, up to a third of patients do not respond to the available therapies sufficiently, if at all. A group of new substances including cannabinoids and neurosteroids were presented at the congress as a possible answer in the search for suitable treatments for severe, therapy-resistant forms of epilepsy. Less invasive neurosurgery techniques and the use of radiotherapies also provide new therapeutic options.

Neurological diseases on the rise – Parkinson’s disease: early detection crucial – Cannabinoids suitable for migraine prevention – Sleep deprivation and disruption harm mind and body – Stroke research: almost three times as many patients could be disability-free.

Neurological diseases on the rise: European collaboration in research essential
EU resources are the top source of funding for cross-border collaboration in neurological research. Prof Günther Deuschl, President of the European Academy of Neurology (EAN) expressed concern about tendencies toward Europe skepticism: “It is only together that we can handle the growing challenges in research.” More than 220 million people in Europe suffer from neurological diseases such as Alzheimer, dementia or headaches and that number is growing all the time.

Parkinson’s disease: early detection crucial, new therapy approaches on the horizon
Detecting Parkinson’s disease before non-reversible symptoms occur: New approaches to early detection are meant to ensure just that. They are based on detection of alpha-synuclein in the skin or intestines. New therapy approaches such as a potential “vaccination” could improve the prognosis of affected individuals in future. Prof Günther Deuschl, President of the European Academy of Neurology (EAN), summarised the latest findings in research on Parkinson’s’ disease.

Data Provide Insight into the Mode of Action of MAVENCLAD™ (Cladribine Tablets) in Patients with Relapsing MS

Roche’s OCREVUS (ocrelizumab) significantly reduced multiple measures of disease progression in relapsing and primary progressive multiple sclerosis

Zebinix® (eslicarbazepine acetate) Data Demonstrate No Significant Negative Consequences on Neurocognitive Function in Children with Focal Epilepsy

 Eslicarbazepine acetate was shown not to have a significant negative consequence on attention, information processing and working memory; 1 in addition it was shown to be efficacious and generally well tolerated2

 Study 208 data presented at the 12th European Paediatric Neurology Society (EPNS) Congress in Lyon, France

22nd June: Bial and Eisai announced data from a Phase II study which showed that treatment with Zebinix® (eslicarbazepine acetate) had no significant negative impact on attention, information processing and working memory in children aged 6-16 years old with focal-onset epilepsy.1 It is well-documented that some anti-epileptic drugs (AEDs) may contribute to negative effects on cognition in epilepsy, underscoring the importance of this clinically meaningful data.3

Data was presented 22nd June in an oral presentation at the EPNS Congress in Lyon, France.1

Study 208 is a randomised Phase II trial evaluating the effect of adjunctive eslicarbazepine acetate (n=83) on Power of Attention in children aged 6-16 years old with refractory focal onset epilepsy versus placebo (n=40). Eslicarbazepine acetate also demonstrated no statistically significant difference for secondary endpoints including continuity of attention, quality of working memory and speed of memory at the end of Part I.1

“Childhood and adolescence are critical times for learning and development,” explains Ann Connolly, Registered Advanced Nurse Practitioner Epilepsy (Childhood), National Children’s Hospital, Adelaide and Meath Hospital, Dublin, Ireland. “These findings may indicate that eslicarbazepine acetate has no significant negative consequence on the neurocognitive capability of children. This is important as the treatment may help support normal learning and schooling, which will stand these children in good stead for the future.”

For the overall age group there were no significant Power of Attention differences in Part I between eslicarbazepine acetate and placebo, with a Least Square mean difference of 33.2 milliseconds (95% CI: – 137.6, 204.0; p=0.700). Power of Attention was defined as the sum of the reaction time measures from the attentional tasks (simple reaction time [dominant hand only], choice reaction time and digit vigilance speed.1 Overall incidence in study 208 of treatment emergent adverse events (TEAEs) was similar (45% for ESL and 48% for placebo).2 The most frequently reported TEAEs with eslicarbazepine acetate treatment were headache, somnolence and vomiting.2

“A major treatment goal for neurologists managing childhood epilepsy is to achieve seizure freedom with minimal or no adverse effects, of which neurocognition is an important consideration. Few clinical trials have examined the cognitive effects of AEDs in childhood epilepsy so this new data is reassuring and supports the use of eslicarbazepine acetate in these difficult-to-treat patients,” commented Professor Stéphane Auvin, Professor of Epilepsy & Child Neurology at the Université Denis Diderot, member of the Paediatric Commission of ILAE and board member of the French Paediatric Neurology Society Paris, France.

Approximately 10.5m children and adolescents worldwide are estimated to have active epilepsy.4 Children with epilepsy may suffer from cognitive impairment and have impaired ability to learn.5 Epilepsy may have a significant impact on a child’s quality of life, academic achievement and psychosocial outcomes in later life.6, 7

Eslicarbazepine acetate is indicated in Europe as adjunctive therapy in adults, adolescents and children aged above 6 years, with partial-onset seizures with or without secondary generalisation.[viii] Eslicarbazepine acetate is also indicated in Europe as a monotherapy in the treatment of partial-onset seizures, with or without secondary generalisation, in adults with newly diagnosed epilepsy.8

New Marketing Authorisation for Zebinix®

European Commission grants Marketing Authorisation for Zebinix® (eslicarbazepine acetate) as once-daily monotherapy in adults with newly diagnosed partial-onset epilepsy 

Bial and Eisai announced on 23rd May that the European Medicines Agency (EMA) has approved Zebinix® (eslicarbazepine acetate) for use as a once-daily monotherapy to treat adults with newly-diagnosed partial-onset epilepsy. Zebinix® is already indicated in Europe as adjunctive therapy in adults, adolescents and children aged above 6 years, with partial-onset seizures with or without secondary generalisation.1

This marketing authorisation is based on results from a Phase III, randomised, double-blind, active-controlled, non-inferiority study (Study 311) which compared once-daily eslicarbazepine acetate as monotherapy to twice-daily, controlled-release carbamazepine in newly diagnosed adults with partial-onset seizures. The primary endpoint was the proportion of patients seizure-free for the entire 26-week evaluation period.2 The data show that 71.1% (n=276/388) of patients for eslicarbazepine acetate and 75.6% (n=300/397) of patients for controlled-release carbamazepine were seizure-free for six months or more, at the last evaluated dose (average risk difference -4.28%; 95% CI -10.3, 1.74%). The one-year seizure-freedom rate at the last evaluated dose was 64.7% (n=251/388) on eslicarbazepine acetate and 70.3% (n=279/397) on controlled-release carbamazepine (average risk difference: -5.46%; 95% CI: -11.88, 0.97%).2

“Epilepsy is a chronic disorder of the brain and one of the most common neurological conditions worldwide,” said Eugen Trinka, Professor and Chair of Department of Neurology, Christian Doppler Klinik, Paracelsus Medical University, Salzburg, Austria. “This approval brings the promise of a new monotherapy option for over half of patients with epilepsy who experience partial-onset seizures.”

Eslicarbazepine acetate has an innovative mode of action that is different from other sodium channel blockers.1,3 It selectively targets the slow inactivated state of the sodium ion channel (which has been implicated in the pathogenesis of epilepsy), preventing its return to the active state,3 and thereby reduces repetitive neuronal firing, based on animal data.3 The recommended starting dose is 400 mg once daily which should be increased to 800 mg once daily after one or two weeks. Based on individual response, the dose may be increased to 1,200 mg once daily. Some patients on a monotherapy regiment may benefit from a dose of 1,600 mg once daily.1

“We are pleased that adults with partial-onset epilepsy across Europe are now able to benefit from a once-daily monotherapy option that is simple to use, which may optimise their adherence,” comments António Portela, CEO of Bial, Porto, Portugal. “Bial has an ongoing commitment to all people living with epilepsy and we look forward to continuing to work with the epilepsy community to bring this new indication to patients.”

“This decision for eslicarbazepine acetate by the European Commission reinforces Eisai’s commitment to researching and developing neurological treatment options that have the potential to help people manage epilepsy more effectively. This milestone means that newly-diagnosed adult patients in Europe who experience partial-onset epilepsy will now have a broader range of treatment options available,” comments Neil West, Vice President EMEA, Global Neurology Business Unit at Eisai.

A safety analysis of the Phase III study showed that the tolerability profile of eslicarbazepine acetate was similar to that of twice-daily controlled-release carbamazepine.4 The side effects of eslicarbazepine acetate were mostly of mild intensity, and consistent with the known safety profile.

Incidence rates of treatment-emergent adverse events (TEAEs) were similar but slightly higher in patients receiving controlled-release carbamazepine (77.7%) (n=320/412) versus eslicarbazepine acetate (75.3%) (n=302/401). Possibly-related TEAEs were also slightly higher at 49.5% (n=204/412) for controlled-release carbamazepine compared with 41.1% (n=165/401) for eslicarbazepine acetate, for serious possibly-related TEAEs (2.7% vs 2.0%) (n=11/412 vs n=8/401), and for TEAEs leading to withdrawal (18.0% vs 13.5%) (n=74/412 vs n=54/401). The most frequently reported possibly-related TEAEs for eslicarbazepine acetate were, in order of most frequent, dizziness, headache, somnolence, fatigue and nausea.4

COPAXONE® no longer contraindicated during pregnancy in the UK

Teva Pharmaceutical Industries Ltd have announced that the label for COPAXONE® (glatiramer acetate) injection 20mg/mL, used for treatment in patients with relapsing forms of multiple sclerosis (RMS), has been updated in the UK to remove the pregnancy contraindication.

The label update followed an extensive analysis by regulatory authorities of available pregnancy cases among women who were already taking COPAXONE® when they learned they were pregnant. A supporting analysis was also provided comparing data from Teva’s Glatiramer Acetate (GA) Pharmacovigilance Database which captured more than 8,000 pregnancies over a period of more than 20 years.

Staying on an MS treatment like COPAXONE® 20 mg/mL is now an option women can discuss with their doctor because COPAXONE® is no longer contraindicated during pregnancy.

As a precautionary measure, it is preferable to avoid the use of COPAXONE® during pregnancy unless the benefit to the mother outweighs the risk to the foetus.

Professor Gavin Giovannoni, Chair of Neurology – Blizard Institute, Barts and The London, said, “People with multiple sclerosis want to live normal lives, but, for many women with relapsing MS, having to decide between planning a family and staying on their treatment to manage relapses is a reality they have to face. This label update provides specialists and their patients with MS, who are considering starting or extending their family, an important option in relation to their treatment of MS during pregnancy.”

EC grants Marketing Authorisation for Zebinix® for the treatment of partial-onset seizures in children

The European Commission (EC) has extended the Marketing Authorisation for Zebinix® (eslicarbazepine acetate) as a once-daily adjunctive treatment for patients aged above six years with partial-onset (focal) seizures with or without secondary generalisation.[i]

Eslicarbazepine acetate was previously indicated only for the adjunctive treatment of adults aged over 18 with partial-onset seizures with or without secondary generalisation.[ii]

The variation to the license is based on data from one Phase III study (305), one Phase II study (208) and from population PK modelling and exposure-efficacy analyses. The Commission considered the efficacy results from the mentioned studies to be acceptable for an extension of the Marketing Authorisation. The safety analyses show no new or unexpected safety ndings and eslicarbazepine acetate does not appear to have negative neurocognitive consequences (power of attention, information processing and working memory).[iii]

Life After Encephalitis: Ross’s Story

This is an edited excerpt from Ross’s Story in Life After Encephalitis by Dr Ava Easton (pages 55-61). Published in 2016 by Psychology Press. Copies can be purchased from The Encephalitis Society (www.encephalitis.info) or from Amazon, among other suppliers.

Ross’s Story

Ross has been feeling unwell for some weeks now, and is being treated for depression and anxiety…

“My dad asked me to go and see his GP. It was probably the tenth visit to a GP in the space of six weeks, but I agreed. This GP prescribed beta-blockers and another anti-depressant. This would be the third anti-depressant drug I had been prescribed in six weeks. I had seen four different GP’s all of whom had different ideas about how to treat me. How did I know who to believe?

The 10th of July was a very bad day…I kept telling my family there was something wrong with me; that it couldn’t just be depression. I started hitting my head against walls to try and knock the burning out of it…I was screaming. I was crying. I was in agony. I was convinced that I was about to die. My parents called 999 and I was taken to hospital for chest x-rays and CT scans of my head. I spent the night terrified that the lumbar puncture that they were planning to do would go wrong and I would end up disabled after it. That next morning a doctor told me that there was nothing wrong with me physically, they weren’t going to do the lumbar puncture, and that I had a mental problem. I was discharged.

I returned to my parent’s home…the tingling started…it was going to happen again. I lost all sense of what was right in the world. The screaming started again…I couldn’t think, and worse, now I couldn’t remember. I couldn’t picture people’s faces in my mind. I started shouting out friends and family names as I thought that if I didn’t I was going to forget them. It literally felt as if memories were draining out of my brain. I was taken back to hospital for the second time in 24 hours…I was discharged for a second time, and the local crisis team visited daily.

Things began to feel a little more under control. I was referred to a psychologist, and I was prescribed an anti-psychotic medication. This made me very dozy but at least it controlled things.

By now I had spent months convinced that it couldn’t be a mental health problem. I had tried everything I could to make myself happy: I had reduced work, taken breaks away, but nothing was helping. Every morning I started the day questioning what the point of the day was; what the point of existing was.

I made it through the next few weeks, then something happened. Life was turning very dark. On the 26th August I was at home on my own. I took a belt, wrapped it around my neck and wedged the end in the top of a closed door. I let the belt take the weight and I was happy that it would soon be over. Fortunately the belt snapped. That night my girlfriend found out what had happened. She rang the crisis team who were close to taking me away with them, but, they didn’t.

On the 30th we were due to fly to Crete. The crisis team said even thinking about going was a bad idea. However, I was determined to try, just to keep some normality in my life. We got in the car but didn’t get far before the panic started. I was trying to get out of a moving car, and my girlfriend turned the car round and headed home. The crisis team were called again – I was placed under section two of the mental health act, and taken to hospital.

I was transferred to a higher security hospital where I remained for seven weeks. My medication was increased to keep me stable and in the October I was transferred to a general hospital, where I was scheduled to see a sleep specialist since my sleep was getting more bizarre.

The sleep specialist looked at me in a new way – in a way other doctors hadn’t. I owe him a lot, probably my life. After being with him for hours, he wrote to the mental health hospital saying I should be reassessed and probably taken off all of the drugs I was on. I was referred to a neurologist, and spent a month in the neurology ward with the consultants searching for an answer. Finally, the test for anti-NMDA receptor encephalitis returned positive. My brain was seriously unwell, and I was immediately started on Intravenous Immunoglobulin (IVIg) treatment.

The 8th of November 2014 is the first day that I remember since the middle of August. I remember lying in a bed thinking “where on earth am I?” In front of me was a notepad with a note from my mum saying I was in hospital and that it was the middle of November.

Looking back, the biggest clue to there being something wrong were my memory issues. With the depression and anxiety we kept finding possible reasons for them, but the memory loss? That was unexplainable. I started to forget pin numbers, passwords, directions, how to use maps, how to put up a tent, I couldn’t remember names or faces. The only explanation anyone provided was I was so stressed that I was just shutting down.

I don’t hold a grudge about what I went through, I just wish they had thought about, and looked for, a cause outside of their own discipline earlier on. Mental Health and Neurology both work with the brain – stronger links between the two may have saved me months of misdiagnosis.”

The Encephalitis Society

Published online: 21/2/17

The Encephalitis Society began life in 1994 when it became clear there was little to no information or support for people affected by encephalitis and their families. Today The Society has the vision:

To live in a world where Encephalitis is as rare as it possibly can be given its eradication is unlikely, and that those affected and their families, have access to early diagnosis, excel- lent management of their condition, timely access to rehabilitation and other forms of social support.

Its primary aim is to ‘Improve the quality of life of all people affected by encephalitis’, and The Society achieves this in three primary ways:

  • Supporting adults and children affected 
by Encephalitis, their families and carers by providing advice and evidence-based information and working at a national and international level to improve services.
  • Raising awareness about the condition and its subsequent problems among relevant professionals, statutory agencies and the general public.
  • Conducting research and work in part- nership with other researchers and their establishments.

The Illness

Encephalitis is inflammation of the brain. The inflammation is caused either by an infection invading the brain (infectious); or through the immune system attacking the brain in error (post-infectious or autoimmune encephalitis). 
Encephalitis is a thief, one that has quietly been at work for hundreds of years, robbing families of their loved ones, and even in those families where the person survives, it often robs them of the person they once knew. Encephalitis steals their capacity to remember as well as their personalities and the types of abilities we all generally take for granted: concentration, attention, thinking, judgement, inhibition. For many there are additional outcomes such as epilepsy and levels of fatigue so great that returning to work or education are mere pipe dreams. This is of course, where the person survives, many don’t. 
For many years statistics around incidence were scarce to non-existent and encephalitis was side-lined into the silo of ‘rare disease’. However due to great work conducted by many committed researchers and their insti- tutions over the last decade we now know 
there are around 6000 people diagnosed with encephalitis in the United Kingdom alone 1
each year. That’s 16 people every day. The authors suggest this may be an underestimate. Not only that but it is thought that, and again this is an underestimate, that encephalitis is costing the NHS around £40 million a year. A gure that does not include the costs of rehabilitation, long-term care, and the loss to the economy from those of working-age unable to return to work.

Therefore encephalitis has a higher incidence than motor neurone disease and certain forms of meningitis.2 Yet, despite encephalitis being more common, these conditions continue to receive a much higher clinical and public profile. Invariably people have not heard of Encephalitis unless it has happened to them or they are caring for a survivor.

Support and Information

Support and information for survivors and family members is critical. Encephalitis is a complex condition to diagnose and manage. Therefore a lot of the information surrounding it is often complex for the uninitiated. The Society takes this information and restructures it in ways that are meaningful for those new to the condition. Information consists of factsheets, newsletters, and guides for adults and families. All the information provided is evidence-based, peer-reviewed and accredited by NHS England. Therefore patients and professionals alike can be assured about the reliability of the material. The Society also provides direct support via phone, email, skype, and chat online. Other services include connecting people in a similar situation, and a burgeoning global network of volunteers. There are also moves afoot to provide more long-term and social support to patients in evolving encephalitis clinics in Oxford and London.

More recently The Society has launched The Encephalitis Society Neuropsychology Service. This operates in the knowledge that neuropsychology is perhaps the primary intervention that, if a person survives, can help support The Society’s primary aim of improving people’s quality of life. The service is operated by a consultant Neuropsychologist and is not established to duplicate the work of the many excellent services around the country. The service is there primarily to pick up people in areas where a neuropsychology service does not exist, and also in areas where waiting lists are detrimental to maximising a person’s potential recovery and rehabilitation (http://www.encephalitis.info/support/neuropsychology-service).

Awareness

The Society’s primary awareness drive is World Encephalitis Day on 22nd February each year (http://www.worldencephalitisday.org). This global day was launched in 2014 and to date has reached more than 20 million people since its inception. 2017 sees landmark buildings and businesses around the world illuminating in red, in order to drive awareness about the condition, through digital and social media channels. There are lots of other ways each year for people to get involved by engaging with their #RED4WED and #ShowYouKnow campaigns as part of the day’s activities.

Research

The Society is involved with a plethora of research studies including two randomised control trials in Oxford and Liverpool. The Society provides a substantial amount of information for professionals each year including an ‘Advances in Research’ guide which acts as an annual archive of the year’s most prom-inent research into the condition. In addition there are a range of initiatives engaging with junior doctors and early years’ researchers such as essay prizes and travel bursaries. The Society also contributes to research financially and has just launch a co-funded PhD fellowship with The University Liverpool. There is also a popular annual conference held in December in London each year and which brings interested professionals up to speed with the latest in the condition.

The Society strives hard to meet its aims and objectives. They achieve a huge amount with few resources, a small team, and with the voluntary contributions of its Board of Trustees and Scientific Advisory Panel.
