Paladin Labs Announced Favourable CADTH Recommendation for XCOPRI™ (cenobamate tablets) Français

September 12, 2023

MONTREAL, Sept. 12, 2023 /CNW/ -- Paladin Labs Inc. announced today that the Canadian Agency for Drugs and Technologies in Health (CADTH) recommended that XCOPRI (cenobamate tablets) be publicly reimbursed as adjunctive therapy in the management of partial-onset seizures in adults with epilepsy who are not satisfactorily controlled with conventional therapy. This recommendation follows Health Canada's approval of XCOPRI on June 12, 2023.

"Current therapies work for nearly 70% of persons with epilepsy," the Canadian Epilepsy Association said in a statement provided as part of the CADTH process. "New drugs like cenobamate bring hope to many."

"The expectations are set high" for cenobamate based on its positive clinical trial results, asserted the Canadian League Against Epilepsy in its CADTH statement.

Paladin Labs will work with federal, provincial and territorial government payers across Canada and their negotiating body, the pan-Canadian Pharmaceutical Alliance, to help secure appropriate access for the medicine. Government officials and public drug plans will determine whether XCOPRI will be available for patients in their respective provinces and territories.

"There is a process for prescription medications like XCOPRI to reach the hands of Canadians in need," said Livio Di Francesco, Vice President & General Manager of Paladin Labs Inc. "We look forward to beginning negotiations for public reimbursement soon and offering XCOPRI to patients who rely on our country's public drug plan system."

About Epilepsy1-3
Epilepsy is a chronic neurological condition affecting ~300,000 Canadians. It is characterized by recurrent, unprovoked seizures. While there are many different types of seizures, they can be grouped into two broad categories based on the location of the brain in which the seizure activity starts: generalized seizures and focal seizures. Focal seizures (also called partial-onset seizures) affect ~60% of people with epilepsy. While many people with epilepsy will respond to anti-seizure medication, ~30% of patients continue to experience seizures despite treatment with currently available medication options.

XCOPRI (cenobamate tablets) is indicated as adjunctive therapy in the management of partial-onset seizures in adults with epilepsy who are not satisfactorily controlled with conventional therapy. It is taken orally, once daily. 

XCOPRI is an anti-seizure medication (ASM) discovered and developed by SK Biopharmaceuticals and SK life science. It is a novel small molecule with a dual mechanism of action. In pre-clinical studies, XCOPRI has been demonstrated to reduce repetitive neuronal firing by inhibiting voltage-gated sodium currents. It is also a positive allosteric modulator of the γ-aminobutyric acid (GABAA) ion channel.4-6 The efficacy and safety of XCOPRI for the treatment of adults with partial-onset seizures (also known as focal-onset seizures) were assessed in two randomized, placebo-controlled, double-blind clinical trials (C013 and C017).7-8 Long-term safety of cenobamate in this population has been studied in open-label safety study (C021).9

XCOPRI is currently marketed in the US as XCOPRI® and Europe under the trademark ONTOZRY®.
