Abstract
The novel dual orexin receptor antagonist daridorexant was approved in 2022 for the treatment of adult patients with insomnia. The aim of this post-marketing study was to measure daridorexant and its major metabolites in breast milk and plasma of 10 healthy lactating subjects. This single-center, open-label study evaluated the transfer of the analytes into breast milk. A single dose of 50 mg was orally administered in the morning. Milk and blood samples were collected pre-dose and over a period of 72 h after dosing. The pharmacokinetics of daridorexant in milk and plasma were assessed including the cumulative amount and fraction of dose excreted, daily infant dose, and relative infant dose. Safety and tolerability were also investigated. All subjects completed the study. Daridorexant was rapidly absorbed into and distributed from plasma. Daridorexant and its major metabolites were measurable in breast milk. The cumulative total amount of daridorexant excreted over 72 h was 0.010 mg, which corresponds to 0.02% of the maternal dose. This corresponds to a mean daily infant dose of 0.009 mg/day and a relative infant dose of less than 0.22% over 24 h. The maternal safety profile was similar to that observed in previous studies. Low amounts of daridorexant and its metabolites were detected in the breast milk of healthy lactating women. Since the exposure and potential effects on the breastfed infant are unknown, a risk of somnolence or other depressant effects cannot be excluded.

Abstract
We present the case of a 67-year-old male with a history of major depressive disorder, panic disorder, treatment refractory hypertension, dyslipidemia, benign prostatic hypertrophy, and environmental allergies who was initially brought to medical attention following an unwitnessed fall. He subsequently developed symptoms of insomnia disorder. Experts in consultation-liaison psychiatry and sleep medicine provide guidance for this clinical scenario based on their experience and a review of current literature, exploring the epidemiology of insomnia disorder and comorbidities in relation to this case. Furthermore, we offer a review of current treatment for insomnia disorder, including non-pharmacologic methods such as cognitive behavioral therapy for insomnia and pharmacotherapy.

Evaluation and management of insomnia in the clinical practice in Italy: a 2023 update from the Insomnia Expert Consensus Group. J Neurol 2024; 271:1668-1679. [PMID: 38063870 DOI: 10.1007/s00415-023-12112-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 11/06/2023] [Accepted: 11/08/2023] [Indexed: 03/28/2024]
Abstract
BACKGROUND Insomnia is the most reported sleep disorder in industrialized countries, affecting, in the chronic form, around 10% of the European population. In Italy, such a percentage seems to be even higher. Although insomnia can be an independent disorder, it is frequently described as comorbid condition and may precipitate, exacerbate, or prolong a broad range of physical and mental disorders. Evaluating and targeting insomnia in the Italian clinical practice should be a priority. METHODS The present expert opinions and recommendations represent an update from 2020 and insights from Insomnia Expert Consensus Group, based on systematic reviews according to PRISMA on available options in Italy from January 2020 to March 2023. RESULTS We evaluated 28 papers among international guidelines, expert opinions, systematic reviews, and meta-analysis produced during the last 26 months. CONCLUSIONS Our findings suggest that symptoms of insomnia must be assessed in the Italian clinical practice by evaluating nocturnal and daytime symptoms, comorbid conditions, and lifestyle. Cognitive behavioral therapy for insomnia should be the first option according to availability. The choice of the drug should be based on different factors including type of insomnia, age, comorbidities, and potential side effects. If the choice would be a Z-drug or a short-acting benzodiazepine (in subjects < 65 years old), the use should be in the short term (≤ 4 weeks). Indeed, eszopiclone, as a new option in Italy, may present a different profile and may be used for up to 6 months, also in the elderly. If the choice is melatonin, it should be used melatonin 2 mg prolonged release in adults ≥ 55 years for up to 13 weeks. A new dual orexin antagonist, daridorexant, is available in Italy; it has been shown to be effective in adults and elderly and it can be used for at least 3 months and up to 1 year.

Clinical usefulness of dual orexin receptor antagonism beyond insomnia: Neurological and psychiatric comorbidities. Neuropharmacology 2024; 245:109815. [PMID: 38114045 DOI: 10.1016/j.neuropharm.2023.109815] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/11/2023] [Accepted: 12/12/2023] [Indexed: 12/21/2023]
Abstract
Orexin is a neurotransmitter produced by a small group of hypothalamic neurons. Besides its well-known role in the regulation of the sleep-wake cycle, the orexin system was shown to be relevant in several physiological functions including cognition, mood and emotion modulation, and energy homeostasis. Indeed, the implication of orexin neurotransmission in neurological and psychiatric diseases has been hypothesized via a direct effect exerted by the projections of orexin neurons to several brain areas, and via an indirect effect through orexin-mediated modulation of sleep and wake. Along with the growing evidence concerning the use of dual orexin receptor antagonists (DORAs) in the treatment of insomnia, studies assessing their efficacy in insomnia comorbid with psychiatric and neurological diseases have been set in order to investigate the potential impact of DORAs on both sleep-related symptoms and disease-specific manifestations. This narrative review aimed at summarizing the current evidence on the use of DORAs in neurological and psychiatric conditions comorbid with insomnia, also discussing the possible implication of modulating the orexin system for improving the burden of symptoms and the pathological mechanisms of these disorders. Target searches were performed on PubMed/MEDLINE and Scopus databases and ongoing studies registered on Clinicaltrials.gov were reviewed. Despite some contradictory findings, preclinical studies seemingly support the possible beneficial role of orexin antagonism in the management of the most common neurological and psychiatric diseases with sleep-related comorbidities. However, clinical research is still limited and further studies are needed for corroborating these promising preliminary results.

Targeting orexin receptors: Recent advances in the development of subtype selective or dual ligands for the treatment of neuropsychiatric disorders. Med Res Rev 2023; 43:1607-1667. [PMID: 37036052 DOI: 10.1002/med.21959] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 03/08/2023] [Accepted: 03/28/2023] [Indexed: 04/11/2023]
Abstract
Orexin-A and orexin-B, also named hypocretin-1 and hypocretin-2, are two hypothalamic neuropeptides highly conserved across mammalian species. Their effects are mediated by two distinct G protein-coupled receptors, namely orexin receptor type 1 (OX1-R) and type 2 (OX2-R), which share 64% amino acid identity. Given the wide expression of OX-Rs in different central nervous system and peripheral areas and the several pathophysiological functions in which they are involved, including sleep-wake cycle regulation (mainly mediated by OX2-R), emotion, panic-like behaviors, anxiety/stress, food intake, and energy homeostasis (mainly mediated by OX1-R), both subtypes represent targets of interest for many structure-activity relationship (SAR) campaigns carried out by pharmaceutical companies and academies. However, before 2017 the research was predominantly directed towards dual-orexin ligands, and limited chemotypes were investigated. Analytical characterizations, including resolved structures for both OX1-R and OX2-R in complex with agonists and antagonists, have improved the understanding of the molecular basis of receptor recognition and are assets for medicinal chemists in the design of subtype-selective ligands. This review is focused on the medicinal chemistry aspects of small molecules acting as dual or subtype selective OX1-R/OX2-R agonists and antagonists belonging to different chemotypes and developed in the last years, including radiolabeled OX-R ligands for molecular imaging. Moreover, the pharmacological effects of the most studied ligands in different neuropsychiatric diseases, such as sleep, mood, substance use, and eating disorders, as well as pain, have been discussed. Poly-pharmacology applications and multitarget ligands have also been considered.

Abstract
OBJECTIVE To review the current pharmacology, pharmacokinetics/pharmacodynamics, safety, and efficacy of daridorexant in patients with insomnia. DATA SOURCES A literature search of PubMed (March 1, 2018, to October 19, 2022) and ClinicalTrials.gov search was conducted using the following terms: daridorexant and ACT-541468. Additional articles were identified by hand from references. STUDY SELECTION AND DATA EXTRACTION We included English-language articles evaluating daridorexant pharmacology, efficacy, or safety in humans for the management of insomnia. DATA SYNTHESIS Daridorexant has a peak plasma concentration of 1-2 hours, terminal half-life of 8 hours, and absolute bioavailability of 61%. Wake after sleep onset (WASO) significantly decreased from baseline to months 1 and 3 in daridorexant 25 (-18.40 and -22.97 min, P < 0.0001) and 50 mg (-28.98 and -29.41 min, P < 0.0001) groups compared with placebo. Latency to persistent sleep (LPS) significantly decreased from baseline to months 1 and 3 for daridorexant 25 mg (-28.17 and -30.73 min, P = 0.0005 and P = 0.0015) and 50 mg (-31.20 and -34.80 min, P < 0.0001). RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING AGENTS Daridorexant can be administered in diverse patient populations because of its tolerability and favorable safety profile. However, due to the lack of large scale studies that directly compare dual orexin receptor antagonists (DORAs), there is not enough data to recommend 1 DORA over another. CONCLUSIONS Daridorexant is well tolerated and has demonstrated significant reductions in LPS and WASO in the treatment of insomnia in adult patients.

Abstract
While new drug approvals by the U.S. Food and Drug Administration (FDA) had remained stable or even increased in the first 2 years of the COVID-19 pandemic, the 37 newly approved drugs in 2022 are considerably less than the 53 and 50 new drugs approved in 2020 and 2021, respectively, and less than the rolling 10-year average of 43. As in previous years of this annual review, we assign these new drugs to one of three levels of innovation: first drug against a condition ("first-in-indication"), first drug using a novel molecular mechanism ("first-in-class"), and "next-in-class," i.e., a drug using an already exploited molecular mechanism. We identify two "first-in-indication" (ganaxolon and teplizumab), 20 (54%) "first-in-class," and 17 (46%) "next-in-class" drugs. By treatment area, rare diseases and cancer drugs were once again the most prevalent (partly overlapping) therapeutic areas. Other continuing trends were the use of accelerated regulatory approval pathways and the reliance on biopharmaceuticals (biologics).

Abstract
BACKGROUND Insomnia is a common sleep disorder that is diagnosed primarily by patients' subjective reported symptoms. Daridorexant is a new dual orexin receptor antagonist that was recently approved by Food and Drug Administration for insomnia characterized by difficulty falling asleep and/or maintaining sleep. MECHANISM OF ACTION, PHARMACODYNAMICS, AND PHARMACOKINETICS The orexin neuropeptide signaling system plays a role in wakefulness, and blocking the wake-promoting neuropeptides results in diminished wake signaling, thus exerting a sedative effect using an entirely different mechanism of action than the classical sleep promoting agents. The drug has quick onset of action, high volume of distribution, and high protein binding. Pharmacokinetics and pharmacodynamic parameters were similar in patients of different sex and age and were not significantly affected by race, body size, or mild-to-moderate kidney impairment. Dose limitation to 25 mg in moderate liver impairment and no use in severe liver impairment are recommended. The drug undergoes hepatic CYP3A4 metabolism; thus, caution with strong CYP3A4 inhibitors and inducers is warranted. CLINICAL TRIALS The drug was approved based on phase 3 trials involving study 1 and study 2. Study 1 noted daridorexant at doses of 25 and 50 mg demonstrated a statistically significant improvement in wake time after sleep onset, latency to persistent sleep, and self-reported total sleep time against placebo at months 1 and 3. Similarly in study 2, compared with placebo, the 25 mg dose demonstrated statistically significant improvement in wake time after sleep onset, latency to persistent sleep, and self-reported total sleep time at months 1 and 3. Treatment-emergent adverse events were similar for daridorexant and placebo, with nasopharyngitis and headache most frequently reported. THERAPEUTIC ADVANCE Daridorexant is a novel agent with demonstrated efficacy in sleep onset and maintenance and decrease in daytime sedation. Preliminary results from a 1-year extension study note similar incidences of mild-to-moderate side effects as noted in previous trials. Further studies are needed to establish its place in the pharmacological treatment of insomnia.

Abstract
BACKGROUND Insomnia is a multi-factorial disorder with conventional treatment options that are not satisfactory for many patients. This metaanalysis analyzed the safety and efficacy of daridorexant. METHODS An electronic database search for RCTs was conducted on Medline via PubMed, Cochrane, and Clinicaltrials.gov using the terms 'Daridorexant,' 'RCT,' 'Insomnia' trials evaluating the efficacy and/or safety of daridorexant for insomnia were included. The data were synthesized using Cochrane review manager version 5.4.1. Cochrane risk of bias 2.0 tool and GRADEpro-GDT were used to assess the methodological and evidence quality, respectively. RESULTS Of 109 searched studies, four trials were included. The risk of treatment-emergent adverse events with 25 mg daridorexant [risk ratio (RR) = 1.12 (0.88, 1.43), p = 0.36; I2 = 0%] and 50 mg daridorexant [RR = 1.25 (0.88, 1.79), p = 0.22; I2 = 28%] and serious adverse events with 25 mg [RR = 0.86 (0.23, 3.19), p = 0.82, I2 = 56%] and 50 mg [RR = 1.32 (0.29, 6.08), p = 0.72, I2 = 52%] was comparable to placebo [Moderate quality evidence]. Risk of nasopharyngitis was also comparable to placebo. The efficacy parameters like wake after sleep onset, latency to persistent sleep, and subjective total sleep time showed significant improvement with daridorexant. The risk of bias is low for three studies and some concern for one. CONCLUSION Daridorexant is a safer and efficacious agent for induction and maintenance of sleep for chronic insomnia. PROSPERO The registration number is CRD42022335233. CLINICAL TRIAL REGISTRATION www.clinicaltrials.gov identifiers are NCT03575104, NCT03545191, NCT03679884, and NCT02839200).
