Fycompa® is the 16th Captisol-enabled™ product approved worldwide
Ligand Pharmaceuticals Incorporated (NASDAQ:LGND) today announced that its partner Eisai Co., Ltd. obtained marketing authorization approval in January 2024 from the Japanese Ministry of Health, Labour and Welfare for the injection formulation of its in-house discovered antiepileptic drug (AED) Fycompa® (perampanel) in Japan as an alternative therapy when oral administration is temporarily not possible. Fycompa is formulated with Captisol®, a Ligand technology.
Fycompa is a first-in-class AED discovered at Eisai's Tsukuba Research Laboratories. The agent is a highly selective, noncompetitive AMPA receptor antagonist that is postulated to reduce neuronal hyper-excitation associated with seizures by targeting glutamate activity at AMPA receptors on postsynaptic membranes. Two oral formulations of Fycompa are available in Japan: a tablet and a fine granule formulation.
"It is essential that patients with epilepsy continue with their course of treatment, even when they are not able to take their medication orally," said Todd Davis, CEO of Ligand. "We are excited that our longtime partner Eisai is the company that is making this possible, and that Captisol is once again proving to be an invaluable building block in drug development by enabling a new formulation that will make a major difference in people's lives."
Ligand first entered into an agreement with Eisai on this product in 2017. Under the terms of the agreement, Ligand is entitled to a royalty on sales of intravenous Fycompa.
About perampanel (Fycompa®)
Perampanel is a first-in-class anti-epileptic agent (AED) discovered and developed by Eisai. With epileptic seizures being mediated by the neurotransmitter glutamate, the agent is a highly selective, noncompetitive AMPA receptor antagonist that reduces neuronal hyperexcitation associated with seizures by targeting glutamate activity at AMPA receptors on postsynaptic membranes. Perampanel is currently approved in more than 75 countries and territories, including Japan, China, and other countries in Europe and in Asia as an adjunctive treatment for partial-onset seizures (with or without secondarily generalized seizures) in patients with epilepsy 12 years of age and older. In addition, perampanel has been approved in more than 70 countries, including Japan, in Europe and in Asia for treatment as an adjunctive therapy for primary generalized tonic-clonic seizures in patients with epilepsy 12 years of age and older. In Japan and China, perampanel is approved for monotherapy and adjunctive use in the treatment of partial-onset seizures (with or without secondarily generalized seizures) in patients with epilepsy 4 years of age and older. In Europe the approved age range is 4 years of age and older for the adjunctive treatment of partial-onset seizures (with or without secondarily generalized seizures) and 7 years of age and older for the treatment as an adjunctive therapy for primary generalized tonic-clonic seizure. A tablet, fine granule formulation and injection formulation have been approved in Japan. An oral suspension formulation and tablet have been approved in Europe and China. In January 2023, the commercial rights in the United States were transferred to Catalyst Pharmaceuticals, Inc.
