Future opportunity

The epilepsy surgery market holds future opportunities with the development of novel therapies targeting refractory and drug-resistant epilepsy. Advances in precision medicine, gene therapy, and neuromodulation promise more personalized treatments, while innovations in digital health and wearable technologies could enhance seizure monitoring and patient adherence. A focus on addressing the underlying causes of epilepsy, beyond symptomatic relief, may lead to groundbreaking therapies and expanded market potential.

Epilepsy Diagnosis & Treatment Market

The World Health Organization (WHO) describes epilepsy as a chronic, non-communicable brain disorder that affects individuals of all ages and contributes to a burden worldwide. It is a neurological disorder characterized by recurrent, unprovoked seizures. A seizure is a sudden, uncontrolled electrical disturbance in the brain that can manifest in various ways, such as convulsions, altered consciousness, unusual sensations, or behaviors. Characteristics of seizures vary and depend on where in the brain the disturbance first starts and how far it spreads. There are transient symptoms that manifest as awareness or consciousness loss, as well as disruptions in movement, emotion, taste, hearing, vision, and other cognitive functions.

In epilepsy, the normal pattern of neuronal activity becomes disturbed due to a series of physiological changes and events such as impaired Na+/K+ ATPase activity, reduced GABA releases from interneurons, calcium overload, loss of hyperpolarization that leads to strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness. Moreover, in the majority of instances worldwide, the pathogenesis is still unknown, which is why the condition is referred to as idiopathic epilepsy.

As per the International League against Epilepsy (ILAE) Classification 2017, seizures are classified as focal onset seizure that originates in a localized area of the brain and includes (simple focal seizure, complex focal seizure), and generalized onset seizures that involve both hemispheres of the brain from the onset (tonic-clonic seizure, myoclonic seizure, atonic seizure, and absence seizure). Based on etiology, seizures are further classified as cryptogenic (unknown cause) and symptomatic seizures that result from an identifiable cause, such as a brain injury or infection.

Furthermore, certain combinations of clinical features and epilepsy types are associated with specific syndromes such as Lennox–Gastaut Syndrome (LGS), Dravet Syndrome, juvenile myoclonic epilepsy, and others. Certain factors, including age, family history, head injury, dementia, brain infections, seizures in childhood, and stroke, may increase the risk of epilepsy

Epilepsy Diagnosis

Epilepsy diagnosis involves a comprehensive evaluation that includes a detailed medical history, neurological examination, and an Electroencephalography (EEG) to detect abnormal brain activity. Imaging tests, such as MRI or CT scans, are used to identify any structural brain abnormalities. Blood tests may be conducted to rule out other conditions, and in some cases, video EEG monitoring or functional imaging is used for more precise analysis. This thorough approach helps determine the presence, type, and potential causes of epilepsy.

Epilepsy Treatment

The management of epilepsy involves a comprehensive approach aimed at controlling seizures, improving the individual’s quality of life, and addressing any associated issues, but none of them is curative. It includes the pharmacological, nonpharmacological (ketogenic diet), and medical device approaches (vagus nerve stimulation [VNS], deep brain stimulation). Medications are the early treatment choice for almost all patients with multiple seizures.

Some patients who only have a single seizure and whose tests do not indicate a high likelihood of seizure recurrence may not need medications. The medications treat the symptoms of epilepsy (seizures) rather than curing the underlying condition. They are highly effective and completely control seizures in most patients (approximately 70%). The drugs prevent seizures from starting by reducing the tendency of brain cells to send excessive and confused electrical signals. The choice of medication depends on a variety of factors, some of which include the type of seizure and type of epilepsy, the likely side effects of the medication, other medical conditions the patient may have, potential interactions with the patient’s other medications, age, gender and cost of the medication.

In principle, anticonvulsant therapy in adults is usually considered after two unprovoked epileptic seizures. Since most patients can be treated successfully with one agent, there is a broad consensus that therapy should be started by choosing a single anti-epileptic drug of the first choice. The advantages of monotherapy are obvious – ease of concordance with a treatment plan, fewer interactions, and fewer side effects. The choice of the first agent is determined by seizure type, tolerability, efficacy, and patient characteristics like age, gender, contraception, or family planning issues. Several anti-epileptic drugs (AEDs) have been approved for the treatment of epileptic patients; generics of most of these therapies are already available in the market, including lamotrigine, sodium valproate, carbamazepine, levetiracetam, topiramate, and others. Certain recently approved epilepsy therapies include XCOPRI, FYCOMPA MOA, NAYZILAM, EPIDIOLEX, BRIVIACT, SYMPAZAN, and others.

Currently, the first-line monotherapy of AEDs can be classified as sodium channel modulators (phenytoin, lacosamide, BRIVIACT), gamma-aminobutyric acid (GABA) receptor modulator (XCOPRI, clobazam, and others), calcium channel blockers, synaptic vesicle protein SV2A modulator, Na+/Ca2+ channel modulators, other mono or combo therapies. While the second line of therapies includes mono or combo AEDs. Furthermore, brain surgery for epilepsy may be considered when other pharmacological and non-pharmacological treatment options have failed to provide adequate seizure control, impacting the person’s quality of life.

Epilepsy Epidemiology

As the Epilepsy diagnosis & treatment market is derived using a patient-based model, the Epilepsy epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total diagnosed prevalent cases of epilepsy, gender-specific diagnosed prevalent cases of epilepsy, diagnosed prevalent cases of epilepsy based on seizure type, diagnosed cases of other types of epilepsies and associated diseases in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan from 2020 to 2034. 

  • In the 7MM, the total Epilepsy diagnosed prevalent cases were nearly 7 million in 2023, which is expected to increase at a CAGR of 0.4% by 2034.
  • In the US, the total diagnosed epilepsy prevalence cases were approximately 3.3 million in 2023, of which nearly 14% of cases were diagnosed in children and 86% in adults; the total cases of epilepsy are expected to increase by 2034.
  • In 2023, the diagnosed prevalent cases in the EU4 and the UK comprised nearly 1.3 million male cases and 1.5 million female cases. These numbers are expected to rise throughout the study period.
  • In 2023, among EU4 and the UK, Germany had the highest number of cases of epilepsy, i.e., 735 thousand, of which nearly 74% of the cases were focal epileptic seizures, 18% were generalized epileptic seizures, while 8% of the cases were other determined or undetermined epileptic seizures. 
  • Among the 7MM, in 2023, Japan accounted for the second highest diagnosed prevalent cases of epilepsy, i.e., 890 thousand cases, these cases are expected to change during the study period.
  • In Japan, among the other types of epilepsies and associated diseases, the highest cases were found in drug-resistant epilepsy/refractory cases, i.e., 82 thousand followed by photosensitivity and childhood absence epilepsy with equal cases, i.e., 44 thousand, in 2023. These cases are expected to change by 2034.

Epilepsy Marketed Drugs

  • LIBERVANT (diazepam buccal film): Aquestive Therapeutics/Atnahs Pharma (Pharmanovia)

LIBERVANT is a buccally, or inside of the cheek, administered film formulation of diazepam, a benzodiazepine intended for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters) that are distinct from a patient’s usual seizure pattern in patients with epilepsy 12 years of age and older. The drug has been developed as an alternative to the device-based products currently available for patients with refractory epilepsy, including rectal gel and nasal spray products. The company has utilized PharmFilm technology to develop a diazepam formulation that is absorbed directly through the buccal mucosa. The buccal mucosa’s wide, relatively immobile, and highly permeable surface area provided the stable and controlled microenvironment needed to optimize adhesion, absorption, and onset of action.

In April 2024, the US FDA approved LIBERVANT (diazepam buccal film) for the acute treatment of intermittent, stereotypic episodes of frequent seizure activity (i.e., seizure clusters, acute repetitive seizures) that are distinct from a patient’s usual seizure pattern in patients with epilepsy between 2 to 5 years of age.

EPIDIOLEX/EPIDYOLEX (cannabidiol), an oral solution, is a clear, colorless-to-yellow liquid containing cannabidiol at 100 mg/mL concentration. Cannabidiol, the active ingredient in EPIDIOLEX, is a cannabinoid that naturally occurs in the Cannabis sativa L. plant. Inactive ingredients include dehydrated alcohol, sesame seed oil, strawberry flavor, and sucralose. EPIDIOLEX contains no ingredient made from a gluten-containing grain (wheat, barley, or rye). The precise mechanisms by which EPIDIOLEX exerts its anticonvulsant effect in humans are unknown.

EPIDIOLEX is approved for the treatment of seizures associated with Lennox-Gastaut syndrome, Dravet syndrome, or tuberous sclerosis complex. Jazz Pharmaceuticals had initiated a Phase III trial to treat children and adolescents living with developmental and epileptic encephalopathy, however, the trial was terminated due to a business decision. The Japanese unit of Jazz Pharmaceuticals has started a trial of the drug for epilepsy in Japan.

  • XCOPRI/ONTOZRY (cenobamate): SK Biopharmaceutical/Angelini Pharma/Ono Pharmaceutical

Cenobamate is a novel antiseizure medication discovered and developed by SK Biopharmaceuticals and SK Life Science. While the precise mechanism by which cenobamate moa exerts its therapeutic effect is unknown, it is believed to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the ion channel ?-aminobutyric acid (GABA-A). Cenobamate is approved in the US for the treatment of partial-onset seizures in adults and is available under the brand name XCOPRI (cenobamate tablets). It can be combined with other ASMs or used alone

Cenobamate moa is also approved in the EU and the UK for the adjunctive treatment of focal-onset (partial-onset) seizures with or without secondary generalization in adult patients with seizures that have not been adequately controlled despite a history of treatment with at least two anti-epileptic medicinal products and is marketed by Angelini Pharma under the brand name ONTOZRY. Additionally, cenobamate moa is in clinical development in Asia, and Ono Pharmaceutical has the rights to develop and commercialize cenobamate moa in Japan. ONO-2017 is being developed in Japan for the treatment of primary-generalized tonic-clonic seizures and partial-onset seizures. Further, cenobamate moa is being investigated for primary generalized tonic-clonic seizures.

AFINITOR DISPERZ/VOTUBIA is an oral inhibitor of the mammalian target of the rapamycin (mTOR) pathway. AFINITOR DISPERZ is the first adjunctive treatment approved in the US, specifically for adult and pediatric patients aged 2 years and older with TSC-associated partial-onset seizures. The product is also approved in more than 30 countries, including EU member states, for treating TSC-associated seizures. AFINITOR works by inhibiting the mammalian target of rapamycin (mTOR), a protein that regulates multiple cellular functions. Treatment with an mTOR inhibitor in animal models of mTOR dysregulation in the brain resulted in prolonged survival, seizure suppression, prevention of the development of new-onset seizures, and prevention of premature death. Additionally, the drug is approved for other indications, including TSC with subependymal giant cell astrocytoma (SEGA). The recommended starting dosage of AFINITOR DISPERZ (everolimus tablets for oral suspension) is 5 mg/m2 orally once daily until disease progression or unacceptable toxicity.

Epilepsy Emerging Drugs

  • XEN1101/Azetukalner: Xenon Pharmaceuticals

XEN1101 is a novel, orally administered, potent, selective KCNQ2/3 (Kv7.2/7.3) potassium channel opener being developed to treat focal onset seizures and primary generalized tonic-clonic seizures (PGTCS). It acts as a neuronal Kv7 voltage-gated potassium channel opener and has been developed to stabilize nerve cells, control action potential burst firing, and reduce brain hyperexcitability as a seizure treatment. The Kv7 potassium channel mechanism has been clinically validated with ezogabine. The FDA approved this earlier generation Kv7 modulator as an adjunctive treatment for adults with focal seizures with or without secondary generalization. XEN1101’s unique composition is chemically designed to improve the potency, selectivity, and pharmacokinetics of ezogabine and is not expected to have ezogabine’s composition-specific tissue pigmentation effects.

The drug is currently being investigated in multiple Phase III clinical trials to treat patients with focal-onset and primary generalized tonic-clonic seizures with topline data anticipated in the second half of 2025. Moreover, the drug is also being developed for major depressive disorder and is undergoing Phase II clinical trials.

Soticlestat (TAK-935), formerly known as OV935, is a potent, highly selective, first-in-class inhibitor of the enzyme cholesterol 24-hydroxylase (CH24H). CH24H is predominantly expressed in the brain and plays a central role in cholesterol homeostasis. CH24H converts cholesterol to 24-S-hydroxycholesterol (24HC), exiting the brain into the blood plasma circulation. It is believed that CH24H is involved in the over-activation of the glutamatergic pathway, which has been shown to play a role in the initiation and spread of seizure activity. TAK-935 is the only molecule with this mechanism of action in clinical development.

Inhibition of CH24H by soticlestat reduces the neuronal levels of 24HC and may improve the excitatory/inhibitory balance in the brain, thereby reducing seizure susceptibility and improving seizure control. Recently the company posted topline results for soticlestat (TAK-935) in patients with dravet syndrome and lennox-gastaut syndrome. Soticlestat showed a consistent and favorable safety and tolerability profile in the studies. Furthermore the company will move forward to discuss the totality of the data with regulatory authorities.

  • BHV-7000 (KB-3061): Biohaven Pharmaceuticals/Knopp Biosciences

BHV-7000 is a potent, selective activator of Kv7.2/7.3 potassium channels, a clinically validated target to regulate the hyperexcitable state in epilepsy. BHV-7000 is structurally and pharmacologically distinct from other potassium channel activators and demonstrates minimal GABAA receptor activation, potentially providing better tolerability. BHV-7000 was potent in the maximal electroshock (MES) preclinical epilepsy model without adverse effects on neurobehavior and was well-tolerated in a Phase I SAD/MAD clinical study without CNS adverse events typical of antiseizure medications.

Currently, Phase II/III studies in focal epilepsy are ongoing. Moreover, the company is also enrolling participants in ongoing pivotal clinical trials with the Kv7 activator, BHV-7000, targeting generalized epilepsy, bipolar disorder, and major depressive disorder.

Note: Further emerging therapies and their detailed assessment will be provided in the final report...

 

Epilepsy Drugs Market Insights

Epilepsy treatment involves various drug classes to control seizures, including sodium channel blockers (e.g., phenytoin, lamotrigine), which stabilize neuronal activity by inhibiting abnormal electrical impulses. Calcium channel blockers (e.g., ethosuximide) are effective for absence seizures, while GABAergic agents (e.g., valproate, benzodiazepines) enhance inhibitory neurotransmission to reduce seizure frequency. Newer-generation AEDs like levetiracetam and topiramate offer broader efficacy with fewer side effects, addressing both generalized and focal seizures. Non-pharmacological options such as vagus nerve stimulation (VNS) and the ketogenic diet are also utilized, particularly in drug-resistant cases, providing additional therapeutic avenues.

 Epilepsy Market Outlook

The Epilepsy treatment paradigm or its management strategies involves three main categories, i.e., pharmacotherapy, surgery, and alternative treatment strategies, including neurostimulation, ketogenic diet, and lifestyle changes. Medical professionals decide the treatment line according to the patient’s condition and the severity of the case. 

The commonly used treatment therapy for epilepsy is anti-epileptic medications (AEDs). The early treatment choice for almost all patients with multiple seizures is AEDs. The medications treat the symptoms of epilepsy (seizures), are highly effective, and completely control seizures in the majority (70%) of cases. The drugs prevent seizures from starting by reducing brain cells’ tendency to send excessive and confused electrical signals.

The choice of medication depends on a variety of factors, some of which include the type of seizure and type of epilepsy, epilepsies syndromes, the likely side effects of the medication, other medical conditions the patient may have, potential interactions with the patient’s other medications, age, gender and cost of the medication. Anticonvulsant therapy is also considered after two unprovoked epileptic seizures. The medication prescribed by the medical practitioner could be monotherapy or a combinational therapy, including two or more products as a medication.

Epilepsy Market Outlook

AEDs that have been tested in rigorous scientific trials and got approval from regulatory authorities, including carbamazepine, cannabidiol, cenobamate moa, brivaracetam, divalproex sodium, clobazam, felbamate, fenfluramine, clonazepam, eslicarbazepine, everolimus, ethosuximide, gabapentin, ganaxolone, lacosamide, lamotrigine, midazolam, levetiracetam, oxcarbazepine, perampanel, phenobarbital, phenytoin, pregabalin, primidone, rufinamide, sodium valproate, stiripentol, tiagabine, topiramate, vigabatrin, valproic acid market, and zonisamide are the mainstay of epilepsy treatment.

However, several drugs have their generic version in the market due to the loss of patent exclusivity. There is a variety of mechanisms of action, and some AEDs possess multiple mechanisms of action. Although precise mechanisms of some drugs remain elusive, antiseizure medications tend to be grouped by their principal mode of action. Some AEDs act on the sodium channels by either blocking their repetitive activation (phenytoin, carbamazepine). Others work on calcium channels by blocking either T-type calcium channels (ethosuximide, valproic acid market) or the N- and L-type calcium channels (zonisamide). Lamotrigine works by blocking sodium channels, N- and L-type calcium channels, and modulating H-current. Topiramate works by blocking sodium channels, alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors, and by inhibiting carbonic anhydrase.

Other mechanisms through which AEDs act are by enhancing gamma-aminobutyric acid (GABA)-A receptors (phenobarbital, benzodiazepines), blocking N-methyl-D-aspartic acid (NMDA) receptors (felbamate), and opening neuronal potassium channels (ezogabine). More detailed descriptions of some of these drugs are provided in the following paragraphs.

Epilepsy treatment is prescribed based on several factors, including rare and severe forms of epilepsy, epileptic syndromes (Dravet syndrome, infantile spasms, tuberous sclerosis complex, Lennox–Gastaut syndrome, etc.), and types of epileptic seizures, focal (simple, complex, and secondary) and generalized (absence seizures, tonic-clonic, myoclonic, tonic, and atonic seizures).

  • ZTALMY (ganaxolone), approved in March 2022 in the US, became the first medication approved to treat seizures associated with CDD in patients 2 years of age and older. It was also approved in Europe in July 2023; however, it was for children from 2 to 17 years of age. Its anticonvulsant effects are thought to result from positive allosteric modulation of the GABAA receptor in the CNS; however, the precise mechanism of action is unknown.
  • EPIDIOLEX, a cannabidiol medication, was approved in the US by the FDA in 2018 and later by EMA in 2019 for patients =2 years of age with Dravet syndrome or LGS. While the mechanism of action of CBD underlying the reduction of seizures in humans is unknown, CBD possesses an affinity for multiple targets, including transient receptor potential vanilloid-1 (TRPV1), the orphan G protein-coupled receptor-55 (GPR55), and the equilibration nucleoside transporter 1 (ENT-1), across a range of target classes, resulting in functional modulation of neuronal excitability, relevant to the pathophysiology of many disease types, including epilepsy.
  • BRIVIACT (brivaracetam [BRV]), an analog of levetiracetam (LEV), was initially approved in 2016 by the US FDA and EMA as an add-on treatment to other medications to treat partial onset seizures in patients aged 16 years and older with epilepsy. However, over time, it received several supplemental, and recently, in 2023, its oral formulation was approved for pediatric epilepsy patients of four years and older. The drug is available for oral and intravenous administration.

Key Epilepsy Drug Companies such as Xenon Pharmaceuticals, Eisai, Biohaven Pharmaceuticals, Knopp Biosciences, and others are evaluating their lead candidates in different stages of clinical development. They aim to investigate their products to treat Epilepsy.

  • The total Epilepsy Treatment Drugs Market Size in the 7MM was approximately USD 9 billion in 2023 and is projected to increase during the forecast period (2024–2034), with a CAGR of approximately 7%.
  • The total Epilepsy Treatment Drugs Market Size in the US was approximately USD 4.3 billion in 2023, accounting for approximately 48% of the total market revenue for the 7MM.

Their opinion helps understand and validate current and emerging therapy treatment patterns or Epilepsy surgery market trends. This will support the clients in potential upcoming novel treatments by identifying the overall scenario of the market and the unmet needs.

Physician’s View

As per the KOLs from the US, about 3 million people in the US and approximately 50 million worldwide are affected due to this chronic non-communicable disease. In addition, men are significantly more likely to experience epilepsy than women. As per the KOLs from the UK, our lack of knowledge, or perhaps lack of suitable diagnostic tools, has made epilepsy economic implications. Moreover, the healthcare expenses and social stigma associated with the disease place a significant financial strain on households. As per the KOLs from Japan, for patients, who are drug-resistant, sometimes the key is figuring out the right medicine combination and that's always exciting. Not everyone is going to be a candidate for epilepsy surgery. We should not give up on finding and developing these breakthroughs in medical management.

Qualitative Analysis

In addition, the scoring is also based on the route of administration, order of entry and designation, probability of success, and the addressable patient pool for each therapy. According to these parameters, the final weightage score and the ranking of the emerging therapies are decided.

Pediatric Epilepsy Market Access and Reimbursement

Reimbursement of rare disease therapies can be limited due to lack of supporting policies and funding, challenges of high prices, lack of specific approaches to evaluating rare disease drugs given limited evidence, and payers’ concerns about budget impact. The high cost of rare disease drugs usually has a limited effect on the budget due to the small number of eligible patients being prescribed the drug. The US FDA has approved several rare disease therapies in recent years. From a patient perspective, health insurance and payer coverage guidelines surrounding rare disease treatments restrict broad access to these treatments, leaving only a small number of patients who can bypass insurance and pay for products independently.

The reimbursement challenges related to medical care and treatment for individuals with Epilepsy can be significant as it often requires specialized medical attention, covering the costs of diagnosis, treatment, and ongoing care. Health insurance plans may not fully cover limited coverage of some medical treatments, therapies, and devices specific to Epilepsy. This can result in high out-of-pocket expenses for families seeking the best care for their loved ones. Moreover, it requires specialized care from healthcare providers with expertise. Finding and accessing such specialists may be challenging, and the associated costs may not always be fully reimbursed by insurance.
