ATLANTA, Nov. 17, 2020 /PRNewswire/ — UCB, a global pharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has approved Vimpat (lacosamide) CV as adjunctive therapy in the treatment of primary generalized tonic-clonic seizures (PGTCS) in patients four years of age and older and Vimpat injection for intravenous use in children four years of age and older.1 PGTCS is a type of seizure that occurs all over the brain, affecting both sides of the brain from the start, causing muscles to stiffen and convulsions to occur for up to a few minutes.2
“These approvals underscore UCB’s commitment to people living with epilepsy and our focus on finding solutions for specific unmet needs within the epilepsy community,” said Mike Davis, Head of U.S. Neurology at UCB. “We are pleased that Vimpat is now available as a treatment option for people living with primary generalized tonic-clonic seizures on their journey to seizure control.”
The PGTCS approval is based, in part, on results of a Phase 3 study recently published in the Journal of Neurology, Neurosurgery & Psychiatry.3 Adjunctive treatment with VIMPAT resulted in a significantly lower risk of developing a second PGTCS during the 24-week treatment period, with the corresponding risk reduction being 45% (p=0.001), and a significantly higher rate of freedom from PGTCS during the treatment period compared with placebo (31.3% vs 17.2%, p=0.011).
People living with generalized tonic-clonic seizures have an increased risk of injury4 and those who experienced three or more in one year had a fifteen-fold increased risk of sudden unexpected death in epilepsy.5
“The treatment of primary generalized tonic-clonic (convulsive) seizures is challenging, with about one-third of patients still being refractory while on therapy,” said David Vossler, MD, FAAN FACNS FAES, Department of Neurology, University of Washington, Seattle, USA. “Bolstered by a wealth of data demonstrating the efficacy and safety of Vimpat, this new indication gives people suffering from PGTCS a chance at freedom from these seizures, which many have never experienced.”
Results from the Phase 3 study showed that Vimpat was generally tolerated in patients with Idiopathic Generalized Epilepsy (IGE) and PGTCS. The most common adverse reactions (≥10%) reported in patients treated with VIMPAT were dizziness (23%), somnolence (17%), headache (14%), and nausea (10%) compared to 7%, 14%, 10%, and 6%, respectively, of patients who received placebo.
Regarding the expanded pediatric population, Vimpat tablets and oral solution were already approved to treat partial-onset seizures in adults and children four years and older as monotherapy and adjunctive therapy. Vimpat injection was previously approved for the treatment of partial-onset seizures only in adult patients (17 years of age and older).
In October 2020, The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion for VIMPAT as adjunctive therapy in the treatment of PGTCS in adults, adolescents and children from four years of age with idiopathic generalized epilepsy.6 Regulatory reviews for use of VIMPAT in the treatment of PGTCS are also underway in Japan and Australia.
Epilepsy is the main symptom of a variety of chronic disorders of the brain. It is the fourth most common neurological condition worldwide and affects approximately 65 million people. Anyone can develop epilepsy; it occurs across all ages, races and genders, and is defined as one or more unprovoked epileptic seizures with a risk of further seizures.7

These forward-looking statements are based on current plans, estimates and beliefs of management. All statements, other than statements of historical facts, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial information, expected legal, arbitration, political, regulatory or clinical results or practices and other such estimates and results. By their nature, such forward-looking statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties and assumptions which might cause the actual results, financial condition, performance or achievements of UCB, or industry results, to differ materially from those that may be expressed or implied by such forward-looking statements contained in this press release. Important factors that could result in such differences include: changes in general economic, business and competitive conditions, the inability to obtain necessary regulatory approvals or to obtain them on acceptable terms or within expected timing, costs associated with research and development, changes in the prospects for products in the pipeline or under development by UCB, effects of future judicial decisions or governmental investigations, safety, quality, data integrity or manufacturing issues; potential or actual data security and data privacy breaches, or disruptions of our information technology systems, product liability claims, challenges to patent protection for products or product candidates, competition from other products including biosimilars, changes in laws or regulations, exchange rate fluctuations, changes or uncertainties in tax laws or the administration of such laws, and hiring and retention of its employees. There is no guarantee that new product candidates will be discovered or identified in the pipeline, or that new indications for existing products will be developed and approved. Movement from concept to commercial product is uncertain; preclinical results do not guarantee safety and efficacy of product candidates in humans. So far, the complexity of the human body cannot be reproduced in computer models, cell culture systems or animal models. The length of the timing to complete clinical trials and to get regulatory approval for product marketing has varied in the past and UCB expects similar unpredictability going forward. Products or potential products which are the subject of partnerships, joint ventures or licensing collaborations may be subject to disputes between the partners or may prove to be not as safe, effective or commercially successful as UCB may have believed at the start of such partnership. UCB’ efforts to acquire other products or companies and to integrate the operations of such acquired companies may not be as successful as UCB may have believed at the moment of acquisition. Also, UCB or others could discover safety, side effects or manufacturing problems with its products and/or devices after they are marketed. The discovery of significant problems with a product similar to one of UCB’s products that implicate an entire class of products may have a material adverse effect on sales of the entire class of affected products. Moreover, sales may be impacted by international and domestic trends toward managed care and health care cost containment, including pricing pressure, political and public scrutiny, customer and prescriber patterns or practices, and the reimbursement policies imposed by third-party payers as well as legislation affecting biopharmaceutical pricing and reimbursement activities and outcomes. Finally, a breakdown, cyberattack or information security breach could compromise the confidentiality, integrity and availability of UCB’s data and systems.
Given these uncertainties, you should not place undue reliance on any of such forward-looking statements. There can be no guarantee that the investigational or approved products described in this press release will be submitted or approved for sale or for any additional indications or labelling in any market, or at any particular time, nor can there be any guarantee that such products will be or will continue to be commercially successful in the future.
UCB is providing this information, including forward-looking statements, only as of the date of this press release and expressly disclaims any duty to update any information contained in this press release, either to confirm the actual results or to report or reflect any change in its forward-looking statements with regard thereto or any change in events, conditions or circumstances on which any such statement is based, unless such statement is required pursuant to applicable laws and regulations.
Additionally, information contained in this document shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any offer, solicitation or sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of such jurisdiction.
