Updated top-line results demonstrate improved outcomes in adults with narcolepsy or idiopathic hypersomnia treated with Xywav as observed in the Phase 4 DUET (Developing Understanding of Hypersomnia by Evaluating Low-Sodium Oxybate Treatment) study Novel analysis of real-world Epidiolex treatment patterns underscore importance of dose optimization for improved patient persistence For U.S. media and investors only DUBLIN, March 19, 2025 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that seven abstracts from across its neuroscience portfolio will be featured at the 77th Annual American Academy of Neurology Meeting (AAN) being held April 5-9, 2025, in San Diego. Data presented at the meeting includes an updated presentation of top-line results of the open-label, single-arm, Phase 4 DUET (Develop hypersomnia Understanding by Evaluating low-sodium oxybate Treatment) trial, evaluating the effectiveness and safety of low-sodium oxybate, Xywav® (calcium, magnesium, potassium, and sodium oxybates) oral solution, on key sleep outcomes and daytime symptoms, including excessive daytime sleepiness (EDS), in adults with narcolepsy or idiopathic hypersomnia (IH). Notably, the results from DUET demonstrated statistically significant improvements from baseline to end of treatment in Epworth Sleepiness Scale (ESS) scores, reduced sleep stage shifts, increased deep sleep and reduced number of awakenings among adults with narcolepsy treated with Xywav. In adults with IH, Xywav treatment also showed improvements in ESS and Idiopathic Hypersomnia Severity Scale scores. Further, new patient-reported data from DUET demonstrated the association of Xywav treatment with improvements in daytime symptoms and functional impacts, including cognitive complaints, among adults with narcolepsy or IH. Xywav is indicated for the treatment of EDS or cataplexy in patients 7 years of age and older with narcolepsy and for adults with idiopathic hypersomnia. "This year's presentations at the AAN Annual Meeting reinforce our ongoing commitment to addressing debilitating neurological disorders, with limited or no treatment options including narcolepsy, idiopathic hypersomnia and epilepsy," said Sarah Akerman, MD, head of neuroscience global medical and scientific affairs of Jazz Pharmaceuticals. "We continually strive to expand our understanding, research and capabilities in neuroscience through ongoing data generation for Xywav and Epidiolex to ensure patients' lived experiences and needs are reflected holistically. By listening to our patients, their care teams and leading industry experts, we aim to better address the unmet needs of those living with these difficult-to-treat conditions and ultimately help redefine possibilities for their lives." Highlights at the 2025 AAN Annual Meeting include: Two presentations showcasing updated results from the open-label, single-arm, Phase 4 DUET trial of adults with narcolepsy or IH, which evaluated the effectiveness and safety of Xywav on key sleep outcomes, daytime symptoms, and functional impacts, including cognitive complaints, work productivity, and daily activities. Novel analysis of real-world Epidiolex® (cannabidiol) treatment patterns from U.S. specialty pharmacy data found the overall probability of persistence at one year was nearly 70% (69.9%) among new patients and underscores the importance of dose optimization. The analysis shows how healthcare providers optimize dosing over time, with half (52%) of patients taking dosages >15 mg/kg/day at 12 months and those taking an average of >20 mg/kg/day having the lowest likelihood of discontinuation. This real-world data demonstrates the importance of dose optimization for long-term persistence, which could lead to improved seizure control and tolerability. The 2025 AAN Annual Meeting abstracts are available online at index.mirasmart.com/AAN2025. A full list of Jazz Pharmaceuticals' presentations follows below: About Xywav® (calcium, magnesium, potassium, and sodium oxybates) oral solution Xywav is the only low-sodium oxybate approved by the U.S. Food and Drug Administration (FDA) for the treatment of cataplexy or excessive daytime sleepiness (EDS) in patients 7 years of age and older with narcolepsy. The FDA recognized seven years of Orphan Drug Exclusivity for Xywav for the treatment of cataplexy or EDS in patients 7 years of age and older with narcolepsy. The Office of Orphan Product Development (OOPD) at the FDA also published its summary of clinical superiority findings for Xywav for the treatment of cataplexy or EDS in patients 7 years of age and older with narcolepsy by means of greater cardiovascular safety compared to Xyrem® (sodium oxybate) oral solution. The decision of the OOPD is based on the FDA findings that Xywav provides a greatly reduced chronic sodium burden compared to Xyrem. Xywav has 131 mg of sodium at the maximum recommended nightly dose whereas other high sodium oxybates have 1640 mg at the equivalent dose. Xywav is comprised of a unique composition of cations resulting in 92% less sodium, or a reduction of approximately 1,000 to 1,500 mg/night at the recommended dose range of 6 g to 9 g/night. Xywav is the only oxybate therapy that does not carry a warning in the label related to use in patients sensitive to high sodium intake. Xywav is also the first and only U.S. FDA-approved treatment option for idiopathic hypersomnia in adults. The FDA recognized seven years of Orphan Drug Exclusivity for Xywav for the treatment of idiopathic hypersomnia in adults. Xywav is the only FDA-approved treatment studied across the multiple symptoms of idiopathic hypersomnia, such as EDS, sleep inertia (severe grogginess or confusion when waking up), long sleep duration and cognitive impairment. Xywav can be administered as a twice- or once-nightly regimen for the treatment of idiopathic hypersomnia in adults. The exact mechanism of action of Xywav in the treatment of adults with idiopathic hypersomnia and of cataplexy and EDS in narcolepsy is unknown. It is hypothesized that the therapeutic effects of Xywav are mediated through GABAB actions during sleep at noradrenergic and dopaminergic neurons, as well as thalamocortical neurons.1 The U.S. Drug Enforcement Agency (DEA) has designated Xywav as a Schedule III medicine. The DEA defines Schedule III drugs, substances, or chemicals as drugs with a moderate to low potential for physical and psychological dependence.1,2 Because of the risks of central nervous system (CNS) depression and abuse and misuse, Xywav is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the XYWAV and XYREM REMS. Important Safety Information for Xywav Contraindications XYWAV is contraindicated in combination with sedative hypnotics or alcohol and in patients with succinic semialdehyde dehydrogenase deficiency. Warnings and Precautions Central Nervous System Depression The concurrent use of XYWAV with other CNS depressants, including but not limited to opioid analgesics, benzodiazepines, sedating antidepressants or antipsychotics, sedating anti-epileptic drugs, general anesthetics, muscle relaxants, and/or illicit CNS depressants, may increase the risk of respiratory depression, hypotension, profound sedation, syncope, and death. If use of these CNS depressants in combination with XYWAV is required, dose reduction or discontinuation of one or more CNS depressants (including XYWAV) should be considered. In addition, if short-term use of an opioid (eg, post- or perioperative) is required, interruption of treatment with XYWAV should be considered. After first initiating treatment and until certain that XYWAV does not affect them adversely (eg, impair judgment, thinking, or motor skills), caution patients against hazardous activities requiring complete mental alertness or motor coordination such as operating hazardous machinery, including automobiles or airplanes. Also caution patients against these hazardous activities for at least 6 hours after taking XYWAV. Patients should be queried about CNS depression-related events upon initiation of XYWAV therapy and periodically thereafter. Abuse and Misuse XYWAV is a Schedule Ill controlled substance. The active moiety of XYWAV is oxybate, also known as gamma-hydroxybutyrate (GHB), a Schedule I controlled substance. Abuse of illicit GHB, either alone or in combination with other CNS depressants, is associated with CNS adverse reactions, including seizure, respiratory depression, decreases in the level of consciousness, coma, and death. The rapid onset of sedation, coupled with the amnestic features of GHB particularly when combined with alcohol, has proven to be dangerous for the voluntary and involuntary user (eg, assault victim). Physicians should carefully evaluate patients for a history of drug abuse and follow such patients closely. XYWAV and XYREM REMS Because of the risks of central nervous system depression and abuse and misuse, XYWAV is available only through a restricted distribution program called the XYWAV and XYREM REMS. Notable requirements of the XYWAV and XYREM REMS include the following: Healthcare Providers who prescribe XYWAV are specially certified XYWAV will be dispensed only by the central pharmacy that is specially certified XYWAV will be dispensed and shipped only to patients who are enrolled in the XYWAV and XYREM REMS with documentation of safe use Further information is available at or 1-866-997-3688. Respiratory Depression and Sleep-Disordered Breathing XYWAV may impair respiratory drive, especially in patients with compromised respiratory function. In overdoses of oxybate and with illicit use of GHB, life-threatening respiratory depression has been reported. Increased apnea and reduced oxygenation may occur with XYWAV administration in adult and pediatric patients. A significant increase in the number of central apneas and clinically significant oxygen desaturation may occur in patients with obstructive sleep apnea treated with XYWAV. Prescribers should be aware that sleep-related breathing disorders tend to be more prevalent in obese patients, in men, in postmenopausal women not on hormone replacement therapy, and among patients with narcolepsy. Depression and Suicidality In Study 1, the randomized-withdrawal clinical trial in adult patients with narcolepsy (n=201), depression and depressed mood were reported in 3% and 4%, respectively, of patients treated with XYWAV. Two patients (1%) discontinued XYWAV because of depression. In most cases, no change in XYWAV treatment was required. In Study 2, the randomized-withdrawal clinical trial in adult patients with idiopathic hypersomnia (n=154), depression and depressed mood were reported in 1% and 3%, respectively, of patients treated with XYWAV. All patients continued XYWAV treatment. Two suicides and two attempted suicides occurred in adult clinical trials with oxybate (same active moiety as XYWAV). One patient experienced suicidal ideation and two patients reported depression in a pediatric clinical trial with oxybate. These events occurred in patients with and without previous histories of depressive disorders. The emergence of depression in patients treated with XYWAV requires careful and immediate evaluation. Monitor patients for the emergence of increased depressive symptoms and/or suicidality while taking XYWAV. Other Behavioral or Psychiatric Adverse Reactions In Study 1, confusion and anxiety occurred in 1% and 5% of patients with narcolepsy treated with XYWAV, respectively. One patient experienced visual hallucinations and confusion after ingesting approximately 9 grams of XYWAV. In Study 2, confusion and anxiety occurred in 3% and 16% of patients with idiopathic hypersomnia, respectively. One patient experienced visual hallucinations, which led to discontinuation of XYWAV. Other neuropsychiatric reactions reported with oxybate (same active moiety as XYWAV) in adult or pediatric clinical trials and in the postmarketing setting include hallucinations, paranoia, psychosis, aggression, agitation, confusion and anxiety. The emergence or increase in the occurrence of behavioral or psychiatric events in patients taking XYWAV should be carefully monitored. Parasomnias Parasomnias can occur in patients taking XYWAV. In Study 1 and Study 2, parasomnias, including sleepwalking, were reported in 6% and 5% of adult patients treated with XYWAV, respectively. In a clinical trial of XYREM (same active moiety as XYWAV) in adult patients with narcolepsy, five instances of sleepwalking with potential injury or significant injury were reported. Parasomnias, including sleepwalking, have been reported in a pediatric clinical trial with sodium oxybate (same active moiety as XYWAV) and in postmarketing experience with sodium oxybate. Episodes of sleepwalking should be fully evaluated and appropriate interventions considered. Most Common Adverse Reactions The most common adverse reactions (occurring in ≥5% of XYWAV-treated patients in adult clinical trials in either narcolepsy or IH) were nausea, headache, dizziness, anxiety, insomnia, decreased appetite, hyperhidrosis, vomiting, diarrhea, dry mouth, parasomnia, somnolence, fatigue, and tremor. In the pediatric clinical trial with XYREM (same active moiety as XYWAV) that included pediatric patients 7 to 17 years of age with narcolepsy, the most common adverse reactions (≥5%) were nausea (20%), enuresis (19%), vomiting (18%), headache (17%), weight decreased (13%), decreased appetite (9%), dizziness (8%), and sleepwalking (6%). The overall adverse reaction profile of XYREM in the pediatric clinical trial was similar to that seen in the adult clinical trial program. The safety profile in pediatric patients with XYWAV is expected to be similar to that of adult patients treated with XYWAV and to that of pediatric patients treated with XYREM. Additional Adverse Reactions Adverse reactions that occurred in 2-<5% of adult patients treated with XYWAV in the Open­ Label Titration and Stable Dose Periods of the randomized-withdrawal study in adult patients with narcolepsy with cataplexy (Study 1) were fatigue, dry mouth, depressed mood, enuresis, irritability, paresthesia, depression, tremor, somnolence, and muscle spasms. Adverse reactions occurring in 2-<5% of patients treated with XYWAV in the IH study include balance disorder, muscle spasms, fall, paresthesia, snoring, weight decreased, bruxism, confusional state, depressed mood, feeling drunk, and irritability. Adverse reactions that occurred in ≥2% of patients in clinical studies with oxybate (but not in Study 1) and which may be relevant for XYWAV, were pain, feeling drunk, pain in extremity, cataplexy, disturbance in attention, sleep paralysis, and disorientation. Discontinuation: In Study 1, 9 of 201 patients (4%) reported adverse reactions that led to withdrawal from the study (anxiety, decreased appetite, depressed mood, depression, fatigue, headache, irritability, nausea, pain in extremity, parasomnia, somnolence, and vomiting). The most common adverse reaction leading to discontinuation was nausea (1.5%). In Study 2, 17 of 154 (11%) patients across all study periods (excluding placebo during the DB RWP) (up to 42 weeks) reported adverse reactions that led to withdrawal from the study (anxiety, nausea, insomnia, vomiting, fatigue, feeling abnormal, fall, decreased appetite, dizziness, paresthesia, tremor, parasomnia, confusional state, hallucination visual, and irritability). The most common adverse reaction leading to discontinuation was anxiety (3.2%). In Study 1 and Study 2, the majority of adverse reactions leading to discontinuation began during the first few weeks of treatment. In the pediatric clinical trial with XYREM (same active moiety as XYWAV), 7 of 104 patients reported adverse reactions that led to withdrawal from the study (hallucination, tactile; suicidal ideation; weight decreased; sleep apnea syndrome; affect lability; anger, anxiety, depression; and headache). Drug Interactions XYWAV is contraindicated in combination with alcohol or sedative hypnotics. Use of other CNS depressants may potentiate the CNS-depressant effects of XYWAV. Concomitant use of sodium oxybate with divalproex sodium results in an increase in systemic exposure to GHB, which was shown to cause a greater impairment on some tests of attention and working memory in a clinical study. A similar increase in exposure is expected with concomitant use of XYWAV and divalproex sodium; therefore, an initial dose reduction of XYWAV is recommended when used concomitantly with divalproex sodium. Prescribers are advised to monitor patient response closely and adjust dose accordingly if concomitant use of XYWAV and divalproex sodium is warranted. Pregnancy and Lactation There are no adequate data on the developmental risk associated with the use of XYWAV or sodium oxybate in pregnant women. XYWAV should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. GHB is excreted in human milk after oral administration of sodium oxybate. There is insufficient information on the risk to a breastfed infant, and there is insufficient information on milk production in nursing mothers. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for XYWAV and any potential adverse effects on the breastfed infant from XYWAV or from the underlying maternal condition. Pediatric Use The safety and effectiveness of XYWAV for the treatment of cataplexy or excessive daytime sleepiness in pediatric patients 7 years of age and older with narcolepsy have been established. XYWAV has not been studied in a pediatric clinical trial for narcolepsy or IH. Use of XYWAV in pediatric patients 7 years of age and older with narcolepsy is supported by evidence from an adequate and well­controlled study of sodium oxybate in pediatric patients 7 to 17 years of age, a study in adults showing a treatment effect of XYWAV similar to that observed with sodium oxybate, pharmacokinetic data of sodium oxybate from adult and pediatric patients, and pharmacokinetic data of XYWAV from healthy adult volunteers. Safety and effectiveness of XYWAV in pediatric patients below the age of 7 years with narcolepsy have not been established. Safety and effectiveness of XYWAV for the treatment of idiopathic hypersomnia in pediatric patients have not been established. Geriatric Use In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Hepatic Impairment The starting dose of XYWAV should be reduced in patients with liver impairment. Dosage Modification in Patients with Hepatic Impairment: The recommended starting dosage in patients with hepatic impairment is one-half of the original dosage per night, administered orally, divided into two doses. Dependence and Tolerance There have been case reports of withdrawal, ranging from mild to severe, following discontinuation of illicit use of GHB at frequent repeated doses (18 g to 250 g per day) in excess of the recommended dosage range. Signs and symptoms of GHB withdrawal following abrupt discontinuation included insomnia, restlessness, anxiety, psychosis, lethargy, nausea, tremor, sweating, muscle cramps, tachycardia, headache, dizziness, rebound fatigue and sleepiness, confusion, and, particularly in the case of severe withdrawal, visual hallucinations, agitation, and delirium. These symptoms generally abated in 3 to 14 days. In cases of severe withdrawal, hospitalization may be required. In the clinical trial experience with XYREM in narcolepsy/cataplexy patients at recommended doses, two patients reported anxiety and one reported insomnia following abrupt discontinuation at the termination of the clinical trial; in the two patients with anxiety, the frequency of cataplexy had increased markedly at the same time. In the XYWAV clinical trial in adult narcolepsy/cataplexy patients at recommended doses, one patient reported insomnia following abrupt discontinuation of XYWAV. In the XYWAV clinical trial in adult idiopathic hypersomnia patients at recommended doses, six patients reported insomnia, two patients reported early insomnia, and one patient reported visual and auditory hallucinations following abrupt discontinuation of XYWAV. Tolerance to XYWAV has not been systematically studied in controlled clinical trials. There have been some case reports of symptoms of tolerance developing after illicit use at dosages far in excess of the recommended XYWAV dosage regimen. About Epidiolex®/Epidyolex® (cannabidiol) Epidiolex/Epidyolex is a prescription, plant-derived cannabis-based medicine administered as an oral solution which contains highly purified cannabidiol (CBD). Cannabidiol, the active ingredient in Epidiolex, is a cannabinoid that naturally occurs in the Cannabis sativa L. plant. The precise mechanisms by which Epidiolex exerts its anticonvulsant effect in humans are unknown. Epidiolex was approved by the U.S. Food and Drug Administration (FDA) for use in the U.S., the European Commission (EC) for use in Europe, the Medicines and Healthcare products Regulatory Agency (MHRA) for use in Great Britain, the Therapeutic Goods Administration for use in Australia, Swissmedic for use in Switzerland, the Food & Nutrition Services of the Israel Ministry of Health for use in Israel, and the New Zealand Medicines and Medical Devices Safety Authority for use in New Zealand, is an oral solution which contains highly purified cannabidiol (CBD). In the U.S., Epidiolex is indicated for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS) or tuberous sclerosis complex (TSC) in patients one year of age and older. Epidiolex has received approval in the European Union under the tradename Epidyolex for adjunctive use in conjunction with clobazam to treat seizures associated with LGS and DS in patients two years and older, and for adjunctive use to treat seizures associated with TSC, in patients two years of age and older. Epidiolex has received Orphan Drug Designation (ODD) from the U.S. FDA for the treatment of seizures associated with LGS, DS, and TSC. Similarly, Epidyolex received ODD from the European Medicines Agency (EMA) for the same indications. Important Safety Information & Indications CONTRAINDICATION: HYPERSENSITIVITY EPIDIOLEX (cannabidiol) oral solution is contraindicated in patients with a history of hypersensitivity to cannabidiol or any ingredients in the product. WARNINGS & PRECAUTIONS Hepatic Injury: EPIDIOLEX can cause dose-related transaminase elevations. Concomitant use of valproate and elevated transaminase levels at baseline increase this risk. Obtain transaminase and bilirubin levels prior to starting treatment, at 1, 3, and 6 months after initiation of treatment, and periodically thereafter, or as clinically indicated. Resolution of transaminase elevations occurred with discontinuation of EPIDIOLEX, reduction of EPIDIOLEX and/or concomitant valproate, or without dose reduction. For patients with elevated transaminase levels, consider dose reduction or discontinuation of EPIDIOLEX or concomitant medications known to affect the liver (e.g., valproate or clobazam). Dose adjustment and slower dose titration is recommended in patients with moderate or severe hepatic impairment. Consider not initiating EPIDIOLEX in patients with evidence of significant liver injury. There have been postmarketing reports of cholestatic or mixed patterns of liver injury. Elevated ammonia levels were reported in some patients with transaminase elevations; most taking concomitant valproate, clobazam, or both. Consider discontinuation or dose adjustment of valproate or clobazam if ammonia is elevated. Somnolence and Sedation: EPIDIOLEX can cause somnolence and sedation that generally occurs early in treatment and may diminish over time; these effects occur more commonly in patients using clobazam and may be potentiated by other CNS depressants. Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including EPIDIOLEX, increase the risk of suicidal thoughts or behavior. Inform patients, caregivers, and families of the risk and advise them to monitor and report any signs of depression, suicidal thoughts or behavior, or unusual changes in mood or behavior. If these symptoms occur, consider if they are related to the AED or the underlying illness. Withdrawal of Antiepileptic Drugs: As with most AEDs, EPIDIOLEX should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus. ADVERSE REACTIONS: The most common adverse reactions in patients receiving EPIDIOLEX (≥10% and greater than placebo) include transaminase elevations; somnolence; decreased appetite; diarrhea; pyrexia; vomiting; fatigue, malaise, and asthenia; rash; insomnia, sleep disorder and poor-quality sleep; and infections. Hematologic abnormalities were also observed. PREGNANCY: EPIDIOLEX should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Encourage women who are taking EPIDIOLEX during pregnancy to enroll in the EPIDIOLEX Pregnancy Surveillance Program and the North American Antiepileptic Drug (NAAED) Pregnancy Registry. DRUG INTERACTIONS: Strong inducers of CYP3A4 and CYP2C19 may affect EPIDIOLEX exposure. EPIDIOLEX may affect exposure to CYP2C19 substrates (e.g., clobazam, diazepam, stiripentol), orally administered P-gp substrates, or other substrates (see full Prescribing Information). Consider dose reduction of orally administered everolimus, with appropriate therapeutic drug monitoring, when everolimus is combined with EPIDIOLEX. A lower starting dose of everolimus is recommended when added to EPIDIOLEX therapy. Concomitant use of EPIDIOLEX and valproate increases the incidence of liver enzyme elevations. Pneumonia was observed more frequently with concomitant use of EPIDIOLEX and clobazam. Dosage adjustment of EPIDIOLEX or other concomitant medications may be necessary. INDICATIONS: EPIDIOLEX (cannabidiol) oral solution is indicated for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), or tuberous sclerosis complex (TSC) in patients 1 year of age and older.

(Nasdaq: ITCI), a biopharmaceutical company focused on the development and commercialization of therapeutics for central nervous system (CNS) disorders, today announced its financial results for the fourth quarter ended December 31, 2024 and provided a corporate update. Financial Highlights Net product sales of CAPLYTA were $680.5 million for the full year 2024. This represents an increase of 47% compared to 2023. Net product sales of CAPLYTA were $199.2 million for the fourth quarter of 2024, compared to $131.5 million for the same period in 2023, representing 51% growth. Selling, general and administrative (SG&A) expenses were $504.5 million for the year ended December 31, 2024 , compared to $409.9 million for the same period in 2023. This increase is primarily due to an increase in commercialization, marketing and infrastructure costs. Research and development (R&D) expenses were $236.1 million for the year ended December 31, 2024 , compared to $180.1 million for the same period in 2023. This increase is primarily due to higher lumateperone and non-lumateperone project costs, including the ITI-1284, ITI-214, and ITI-1500 programs. Cash, cash equivalents, investment securities, and restricted cash totaled $1.0 billion on December 31, 2024 , compared to $499.7 million at December 31, 2023 . Commercial and Clinical Highlights In the first quarter of 2025, we commenced a field sales force expansion in anticipation of the potential approval of CAPLYTA for the adjunctive treatment of MDD. The FDA has accepted for review the sNDA for lumateperone, an investigational agent for the treatment of MDD as adjunctive therapy. Two positive Phase 3 global placebo-controlled studies, Study 501 and Study 502, as well as the long term open-label safety Study 503, form the basis of the sNDA. Advancing our pipeline: In 2024, we initiated 10 late-stage clinical trials including six Phase 3 lumateperone clinical trials and four ITI-1284 clinical trials.Lumateperone: In our pediatric program, in the fourth quarter of 2024, we commenced patient enrollment in two Phase 3 studies in pediatric patients for the treatment of irritability associated with autism spectrum disorder. Patient enrollment is ongoing in our double-blind, placebo-controlled study in bipolar depression and in our open-label safety study in schizophrenia and bipolar disorder in pediatric patients.Patient enrollment is ongoing in our two Phase 3 studies evaluating lumateperone in adults in the acute treatment of manic or mixed episodes associated with bipolar I disorder (bipolar mania). ITI-1284-ODT-SL program: Patient enrollment is ongoing in two Phase 2 clinical studies evaluating ITI-1284 in patients with generalized anxiety disorder (GAD). Our first study evaluates ITI-1284 as an adjunctive therapy to approved GAD medications while a second study evaluates ITI-1284 as monotherapy.Patient enrollment continues in a Phase 2 clinical study evaluating ITI-1284 in patients with psychosis associated with Alzheimer’s disease (AD) and in our Phase 2 program in agitation associated with AD. Other pipeline programs:Phosphodiesterase type I inhibitor (PDE1) program: Patient enrollment in our lenrispodun (ITI-214) Phase 2 Study in Parkinson’s disease (PD) is ongoing. Our second PDE1 inhibitor, ITI-1020 being developed in oncology indications, continues its Phase 1 single ascending dose study in healthy volunteers.ITI-1500 non-hallucinogenic neuroplastogen program: ITI-1549 is advancing IND enabling studies. Important Safety Information Boxed Warnings: Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. CAPLYTA is not approved for the treatment of patients with dementia-related psychosis. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adults in short-term studies. All antidepressant-treated patients should be closely monitored for clinical worsening, and for emergence of suicidal thoughts and behaviors. The safety and effectiveness of CAPLYTA have not been established in pediatric patients. Contraindications: CAPLYTA is contraindicated in patients with known hypersensitivity to lumateperone or any components of CAPLYTA. Reactions have included pruritus, rash (e.g., allergic dermatitis, papular rash, and generalized rash), and urticaria. Warnings & Precautions: Antipsychotic drugs have been reported to cause: Cerebrovascular Adverse Reactions in Elderly Patients with Dementia-Related Psychosis, including stroke and transient ischemic attack. See Boxed Warning above. Neuroleptic Malignant Syndrome (NMS), which is a potentially fatal reaction. Signs and symptoms include: high fever, stiff muscles, confusion, changes in breathing, heart rate, and blood pressure, elevated creatinine phosphokinase, myoglobinuria (and/or rhabdomyolysis), and acute renal failure. Patients who experience signs and symptoms of NMS should immediately contact their doctor or go to the emergency room. Tardive Dyskinesia, a syndrome of uncontrolled body movements in the face, tongue, or other body parts, which may increase with duration of treatment and total cumulative dose. TD may not go away, even if CAPLYTA is discontinued. It can also occur after CAPLYTA is discontinued. Metabolic Changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain. Hyperglycemia, in some cases extreme and associated with ketoacidosis, hyperosmolar coma or death, has been reported in patients treated with antipsychotics. Measure weight and assess fasting plasma glucose and lipids when initiating CAPLYTA and monitor periodically during long-term treatment. Leukopenia, Neutropenia, and Agranulocytosis (including fatal cases). Complete blood counts should be performed in patients with pre-existing low white blood cell count (WBC) or history of leukopenia or neutropenia. CAPLYTA should be discontinued if clinically significant decline in WBC occurs in absence of other causative factors. Decreased Blood Pressure & Dizziness. Patients may feel lightheaded, dizzy or faint when they rise too quickly from a sitting or lying position (orthostatic hypotension). Heart rate and blood pressure should be monitored and patients should be warned with known cardiovascular or cerebrovascular disease. Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension. Falls. CAPLYTA may cause sleepiness or dizziness and can slow thinking and motor skills, which may lead to falls and, consequently, fractures and other injuries. Patients should be assessed for risk when using CAPLYTA. Seizures. CAPLYTA should be used cautiously in patients with a history of seizures or with conditions that lower seizure threshold. Potential for Cognitive and Motor Impairment. Patients should use caution when operating machinery or motor vehicles until they know how CAPLYTA affects them. Body Temperature Dysregulation. CAPLYTA should be used with caution in patients who may experience conditions that may increase core body temperature such as strenuous exercise, extreme heat, dehydration, or concomitant anticholinergics. Dysphagia. CAPLYTA should be used with caution in patients at risk for aspiration. Drug Interactions: CAPLYTA should not be used with CYP3A4 inducers. Dose reduction is recommended for concomitant use with strong CYP3A4 inhibitors or moderate CYP3A4 inhibitors. Special Populations: Newborn infants exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. Dose reduction is recommended for patients with moderate or severe hepatic impairment.

About CAPLYTA (lumateperone) CAPLYTA 42 mg is an oral, once daily atypical antipsychotic approved in adults for the treatment of schizophrenia and the treatment of depressive episodes associated with bipolar I or II disorder (bipolar depression) as monotherapy and as adjunctive therapy with lithium or valproate. While the mechanism of action of CAPLYTA is unknown, the efficacy of CAPLYTA could be mediated through a combination of antagonist activity at central serotonin 5-HT2A receptors and postsynaptic antagonist activity at central dopamine D2 receptors. Lumateperone is being studied for the treatment of major depressive disorder, and other psychiatric and neurological disorders. Lumateperone is not FDA-approved for these disorders.
