Idorsia will supply finished drug product for the agreed territories.

QUVIVIQ – a different kind of insomnia treatment
Insomnia affects millions worldwide, yet commonly used treatments can lead to next-day drowsiness, dependence, and withdrawal symptoms – leaving a clear unmet need for safer, effective alternatives.

Discovered by Idorsia, QUVIVIQ works differently from traditional hypnotics. As a dual orexin receptor antagonist, it selectively targets the orexin system, helping to regulate overactive wake signaling without broadly suppressing brain activity. Its optimized pharmacokinetics promote restorative sleep throughout the entire night, reducing morning sleepiness and improving daytime functioning.

Clinical trials published in The Lancet Neurology demonstrated that daridorexant significantly improved sleep onset, sleep maintenance, and self-reported total sleep time at 25mg and 50mg doses compared to placebo. Daridorexant 50 mg also demonstrated a highly significant improvement in daytime functioning compared to placebo.

Global availability
QUVIVIQ is marketed by Idorsia in North America and Europe, and is available in key international markets in Asia-Pacific and the Middle East through commercial partnerships. Idorsia also has a license and supply agreement for Latin America. This collaboration with Jamjoom Pharma further strengthens Idorsia’s commitment to building QUVIVIQ into a global brand.

Notes to the editor

About insomnia
Insomnia is defined as a combination of dissatisfaction with sleep and a significant negative impact on daytime functioning. Dissatisfaction with sleep refers to the difficulty initiating and/or maintaining sleep on at least three nights per week for at least three months, despite adequate opportunity to sleep. Insomnia is a condition of overactive wake signaling and studies have shown that areas of the brain associated with wakefulness remain more active during sleep in patients with insomnia.

Insomnia as a disorder is quite different from a brief period of poor sleep, and it can take its toll on both physical and mental health. It is a persistent condition with a negative impact on daytime functioning. Idorsia’s research has shown that poor-quality sleep can affect many aspects of daily life, including the ability to concentrate, mood, and energy levels.

The goals of managing insomnia are to improve sleep quality and quantity, as well as daytime functioning. Current recommended treatment of insomnia includes sleep hygiene recommendations, cognitive behavioral therapy and pharmacotherapy.
