Takeda Announces Positive Results from Two Pivotal Phase 3 Studies of Oveporexton (TAK-861) in Narcolepsy Type 1
Article content – Both Phase 3 Studies Met all Primary and Secondary Endpoints Demonstrating Statistically Significant Improvements Across Symptoms at All Doses, Building Upon Phase 2b Results – Oveporexton was Generally Well-Tolerated in Phase 3 Safety Profile – Takeda is Rapidly Advancing Regulatory Submissions and Launch Preparedness with the Aim to Bring Oveporexton to People Living with Narcolepsy Type 1 as Quickly as Possible – These Results Mark a Major Advancement Toward Transforming the Standard of Care by Addressing the Underlying Cause of Narcolepsy Type 1 OSAKA, Japan & CAMBRIDGE, Mass. — Takeda ( TSE:4502/NYSE:TAK) today announced that all primary and secondary endpoints were met in two Phase 3 randomized, double-blind, placebo-controlled studies of oveporexton (TAK-861), a potential first-in-class investigational oral orexin receptor 2 (OX2R)-selective agonist, in narcolepsy type 1 (NT1). NT1 is caused by the loss of orexin-producing neurons in the brain. Orexin agonists are designed to address this underlying orexin deficiency. For the first time, this mechanism of action has been validated in Phase 3 studies demonstrating significant improvement across a broad range of symptoms. These results reinforce the potential of oveporexton to transform the standard of care. Article content 'We are thrilled to reach this pivotal milestone for the oveporexton program. Oveporexton is a testament to Takeda's strength in discovering and developing a potential new class of medicines for difficult to treat diseases such as narcolepsy type 1,' said Christophe Weber, president and chief executive officer at Takeda. 'Our leadership in orexin biology and building a multi-asset orexin franchise with transformative potential will position Takeda for long-term future growth.' Article content The FirstLight (TAK-861-3001) and RadiantLight (TAK-861-3002) studies were two large, global Phase 3 studies conducted in 19 countries. Both studies achieved statistically significant improvement compared to placebo with p-values of <0.001 for all primary and secondary endpoints across all doses at week 12. The primary and secondary endpoints measuring objective and patient reported improvements in wakefulness, excessive daytime sleepiness, cataplexy, ability to maintain attention, overall quality of life and daily life functions demonstrate statistically significant and clinically meaningful improvements achieving near normal ranges across the broad range of symptoms investigated. Article content Oveporexton was generally well-tolerated with a safety profile from the Phase 3 studies overall consistent with oveporexton studies to date including the Phase 2b study. No serious treatment-related adverse events were reported. The most common adverse events were insomnia, urinary urgency and frequency. More than 95 percent of the participants who completed the studies enrolled in the ongoing long-term extension (LTE) study. Article content 'We are grateful to the patients who took part in these clinical studies and to their families, the investigators and clinical staff. The studies were accelerated at an unprecedented pace with the aim to bring this potential treatment to people living with narcolepsy type 1 as quickly as possible,' said Andy Plump, M.D., Ph.D., president of R&D at Takeda. 'The comprehensive assessments from our Phase 3 studies build on the transformative results we saw with our Phase 2b study with most participants reaching normative ranges and reporting clinically meaningful improvement across a broad range of symptoms at the end of the 12-week treatment period. The positive results also reinforce the continued momentum for our late-stage pipeline, which we believe will deliver value to the patients we serve around the world.' Article content Takeda intends to present the results at upcoming medical congresses and plans to submit a New Drug Application with the United States Food and Drug Administration and additional global regulatory authorities in fiscal year 2025. Article content Results from the Phase 3 studies have no significant impact on the full year consolidated forecast for the fiscal year ending March 31, 2026. Article content About Narcolepsy Type 1 (NT1) and Orexin Science Article content NT1 is a chronic, rare neurological disease that results in a range of debilitating symptoms including excessive daytime sleepiness (EDS), cataplexy, disrupted nighttime sleep, sleep paralysis and hallucinations upon falling asleep or waking. Additionally, individuals living with NT1 often report cognitive symptoms, including difficulty thinking clearly, remembering, concentrating and paying attention. NT1 is caused by loss of the orexin-producing neurons in the brain, which regulate wakefulness and sleep, and is also believed to be essential to other functions such as attention through activation of orexin receptors. Currently, the standard of care is limited to symptomatic therapies that may only partially address some of the symptoms people face. Article content About Oveporexton (TAK-861) Article content Oveporexton (TAK-861) is an investigational orexin receptor 2 (OX2R)-selective agonist, which selectively stimulates the OX2R to restore signaling and address the underlying orexin deficiency that causes narcolepsy type 1 (NT1). By activating OX2Rs, oveporexton is designed to promote wakefulness and reduce abnormal rapid eye movement (REM)-sleep like phenomena, including cataplexy, to address the broad spectrum of daytime and nighttime symptoms. Article content FirstLight (TAK-861-3001; NCT06470828) and RadiantLight (TAK-861-3002; NCT06505031) are global, multicenter, placebo-controlled studies to evaluate the efficacy, safety and tolerability of oveporexton compared to placebo in patients with narcolepsy type 1 (NT1) over 12 weeks. The studies were conducted in 19 countries with enrollment completed within six months. The FirstLight study enrolled 168 participants randomized to one of three dosing arms (high dose, low dose and placebo). The RadiantLight study enrolled 105 participants randomized to two dosing arms (high dose and placebo). The primary endpoint in both studies was improvement in excessive daytime sleepiness (EDS) as measured by the Maintenance of Wakefulness Test (MWT), a standard measure of wakefulness. Key secondary endpoints included improvement in EDS as measured by the Epworth Sleepiness Scale (ESS) and in the Weekly Cataplexy Rate (WCR), a measure evaluating cataplexy. The studies also evaluated the effect of oveporexton on participants' ability to maintain attention, participants' overall quality of life, the spectrum of narcolepsy symptoms and daily life functions, as well as the safety and tolerability of oveporexton. Article content About Takeda's Orexin Agonists for Sleep-Wake Disorders Article content Takeda is leading the field of orexin science with a multi-asset franchise. Orexin is a key regulator of sleep and wake patterns and contributes to other essential functions including attention, mood, metabolism and respiration. Oveporexton (TAK-861) is the lead investigational orexin receptor 2 (OX2R) agonist asset in Takeda's orexin franchise and received Breakthrough Therapy designation for the treatment of excessive daytime sleepiness in narcolepsy type 1 (NT1) from the U.S. Food and Drug Administration and the Center for Drug Evaluation of China's National Medical Products Administration. The company is also investigating other orexin agonists in populations with orexin levels in the normal range, including TAK-360, an oral OX2R agonist initially being investigated for the treatment of narcolepsy type 2 (NT2), idiopathic hypersomnia (IH), and other potential indications where orexin signaling is implicated.

Harmony Biosciences Presents Preclinical Data Demonstrating Significant Wake-Promoting and Cataplexy-Suppressing Effects of BP1.15205 in Narcolepsy at SLEEP 2025
PLYMOUTH MEETING, Pa.--(BUSINESS WIRE)--Harmony Biosciences Holdings, Inc. (Nasdaq: HRMY) today announced the presentation of preclinical pharmacological effect data for BP1.15205, an investigational, highly potent, and potentially best-in-class orexin 2 receptor (OX2R) agonist, which demonstrated significant wake-promoting and cataplexy-suppressing effects in a standard transgenic mouse model of narcolepsy type 1. The data will be presented at the 39 th Annual Meeting of the Associated Professional Sleep Societies (APSS) 'SLEEP' on Wednesday, June 11, 2025, at 10:00 AM PDT in Seattle. 'We are encouraged by the robust preclinical data being presented at SLEEP, highlighting BP1.15205 as a potentially best-in-class OX2R agonist,' said Kumar Budur, MD, MS, Chief Medical and Scientific Officer at Harmony Biosciences. 'BP1.15205 is a new and unique chemical scaffold optimized for high potency that demonstrated statistically significant wake-promoting effects at very low doses administered orally in the standard transgenic mouse model. These findings are supportive of dosing flexibility to potentially treat all three central disorders of hypersomnolence at low doses, which could offer an optimized benefit / risk profile. The 3-month GLP toxicity study in two species revealed no concerning adverse events and supports a favorable safety and tolerability profile.' Orexin receptor functional studies showed that BP1.15205 is a highly potent, selective OX2R receptor agonist with no off-target effects expected and a >600-fold selectivity over human OX1R. BP1.15205 is orally bioavailable and has the potential for once-daily dosing. Absorption, distribution, metabolism, and excretion (ADME) properties and preliminary toxicology studies showed that BP1.15205 is a differentiated OX2R agonist drug candidate. In the GLP toxicity study, no adverse events or biochemical changes were observed following a 3-month treatment period at doses up to 300 mg/kg/day, pending histopathology data. An Investigational Medicinal Product Dossier (IMPD) application with the European Medicines Agency (EMA) is being completed for BP1.15205. A first-in-human study is planned to begin in 2H 2025 with topline data anticipated in 2026. Additionally, an Investigational New Drug (IND) application for BP1.15205 will be filed with the U.S. Food and Drug Administration (FDA). 'We are very excited to advance our potentially best-in-class OX2R program and support the strategic expansion of our sleep-wake franchise. We are dedicated to investigating this potential new solution further with the hope of bringing a novel treatment to market that can help even more people with narcolepsy and other central disorders of hypersomnolence,' Budur added. The poster entitled, 'BP1.15205, a Novel Orexin-2 Receptor Agonist, Demonstrates Pharmacological Effects in a Mouse Model of Narcolepsy,' will be presented at P-38; Poster Board Number 1; on June 11, 2025, at 10:00 AM PDT. KEY FINDINGS FROM THE STUDIES INCLUDE: In Vitro Orexin Receptor Functional Studies: BP1.15205 is a highly potent agonist at OX2R receptors: EC 50 = 0.015 nM. BP1.15205 is highly selective for human OX2R receptors: >600-fold selectivity over human OX1R receptors. Minimal interspecies difference in agonist functional properties was observed between human and mouse orexin-2 receptors. In Vivo Pharmacology Studies: Single oral dose administration of BP1.15205 in transgenic mice at the beginning of the 12-hour dark period of a 24-hour light/dark cycle produced significant and dose-dependent increases in total wakefulness time and sleep latency at every dose tested beginning at 0.03 and 0.1 mg/kg, respectfully, as compared to vehicle-treated animals. Significant and dose-dependent decreases in the total number and duration of cataplexy-like episodes were measured following single dose, oral administration of BP1.15205 beginning at 1mg/kg, as compared to vehicle. About Narcolepsy Narcolepsy is a rare, chronic, debilitating neurological disease of sleep-wake state instability that impacts approximately 170,000 Americans and is primarily characterized by excessive daytime sleepiness (EDS) and cataplexy – its two cardinal symptoms – along with other manifestations of REM sleep dysregulation (hallucinations and sleep paralysis), which intrude into wakefulness. EDS is the inability to stay awake and alert during the day and is the symptom that is present in all people living with narcolepsy. In most patients, narcolepsy is caused by the loss of hypocretin/orexin, a neuropeptide in the brain that supports sleep-wake state stability. This disease affects men and women equally, with typical symptom onset in adolescence or young adulthood; however, it can take up to a decade to be properly diagnosed. About Harmony Biosciences Harmony Biosciences is a pharmaceutical company dedicated to developing and commercializing innovative therapies for patients with rare neurological diseases who have unmet medical needs. Driven by novel science, visionary thinking, and a commitment to those who feel overlooked, Harmony Biosciences is nurturing a future full of therapeutic possibilities that may enable patients with rare neurological diseases to truly thrive. Established by Paragon Biosciences, LLC, in 2017 and headquartered in Plymouth Meeting, Pa., we believe that when empathy and innovation meet, a better future can begin; a vision evident in the therapeutic innovations we advance, the culture we cultivate, and the community programs we foster.
