Brexpiprazole

Intra-Cellular Therapeutics' antipsychotic Caplyta (lumateperone) has duplicated its success in treating major depressive disorder (MDD), achieving a second Phase III win just two months after its initial triumph. The data solidifies Caplyta's efficacy and safety profile as a potential new contender in MDD, fueling blockbuster hopes for the drug.On Tuesday, Intra-Cellular reported that Caplyta met the primary and key secondary endpoints in the 480-patient Study 502 when used as an adjunct to antidepressants. The 42mg dose provided a 4.5-point reduction on the Montgomery-Åsberg Depression Rating Scale (MADRS) at week 6 compared to placebo. Patients who received Caplyta in addition to standard antidepressants achieved an MADRS improvement of 14.7 points, compared to an improvement of just 10.3 points seen with placebo."These results, further support our vision for Caplyta to become a leading option for patients and providers across mood disorders," said CEO Sharon Mates. The success follows April's first Phase III win in the Study 501 trial, where Caplyta demonstrated a 4.9-point MADRS advantage over placebo when used as adjunctive therapy to antidepressants.Buyout targetWith this second late-stage success, RBC Capital Markets analyst Brian Abrahams forecasts a "straightforward path for approval and commercialisation" in MDD that could expand Caplyta revenues with a $1.7-billion additional opportunity and bring its total US sales to more than $3 billion annually. The drug, an atypical antipsychotic of the butyrophenone class, was originally approved by the FDA in 2019 as a once-daily oral treatment for schizophrenia, and then expanded to include bipolar depression in 2021."With consistent, strong positive data...[we] see continued appreciation potential for shares to better reflect the value and scarcity of their de-risked, likely multi-blockbuster asset in the neuropsych space," Abrahams stated, suggesting a potential takeover could even emerge down the road.In an interview with FirstWord in April after the Study 501 readout, key opinion leader (KOL) Christoph Correll said the data boded well for Study 502 and that Intra-Cellular likely wouldn't need to wait for results from a third trial – the open label roll-over Study 503 assessing long-term safety – before seeking a label expansion. For more, see – KOL Views Q&A: Intra-Cellular's Caplyta emerges as a threat to the established order in MDD.Indeed, the company said it now plans to submit a supplemental new drug application for Caplyta's in MDD in the second half.Eating away at Vraylar, RexultiCaplyta also exhibited a favourable safety profile. Pooled safety data from both studies 501 and 502 showed mostly mild-to-moderate side effects like dizziness, dry mouth, somnolence and nausea that resolved over the course of the trials, Intra-Cellular said.Moreover, the lack of metabolic issues like weight gain could help differentiate it from antidepressants like AbbVie's Vraylar (cariprazine) and Rexulti (brexpiprazole) from Otsuka and Lundbeck. "Caplyta will cannibalise mostly Vraylar and Rexulti," Correll predicted. From an efficacy standpoint, Vraylar led to a 2.1- to 2.6-point improvement in symptoms compared to placebo on the MADRS scale, while Rexulti bested placebo by 2 to 3.2 points.See – KOL Views Q&A: Expert previews a changing treatment landscape ahead for MDD.

These data represent one of the largest clinical development programs to date for adults living with PTSD and a significant development in a therapy area that hasn’t seen a new approval for a pharmacological treatment in more than 20 years.1,2,3 These data showed that brexpiprazole in combination with sertraline improved symptoms of PTSD in two out of the three studies, based on the primary endpoint of change in CAPS-5 total scores from Week 1 to Week 10 compared to sertraline plus placebo.1 Brexpiprazole in combination with sertraline was associated with greater improvements across the four symptom clusters of PTSD (re-experiencing, avoidance, negative cognition/mood and arousal/reactivity symptoms), compared to sertraline plus placebo.4 No new safety observations related to brexpiprazole were identified.2 Based on these data, Otsuka and Lundbeck submitted a supplemental New Drug Application (sNDA) in April to the U.S. Food and Drug Administration (FDA) for brexpiprazole in combination with sertraline for the treatment of adults living with PTSD. PRINCETON, N.J. & DEERFIELD, Ill.--(BUSINESS WIRE)-- Otsuka Pharmaceutical Development & Commercialization, Inc. (Otsuka) and Lundbeck Pharmaceuticals LLC (Lundbeck) today presented results from the Phase II (Trial 061) and Phase III trials (Trial 071 and 072) evaluating the safety and efficacy of brexpiprazole in combination with sertraline for the treatment of adults with post-traumatic stress disorder (PTSD).1,2 The findings were presented at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting in Miami. This press release features multimedia. View the full release here: The primary endpoint for all three trials was the change from Week 1 to Week 10 in the CAPS-5 total score for brexpiprazole and sertraline combination therapy versus sertraline plus placebo in patients diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).1 The trials were randomized, double blind, active-controlled, and Trial 061 and 071 were flexible dose trials, while Trial 072 was a fixed dose trial.1 In Trial 061 and 071, brexpiprazole in combination with sertraline was associated with a statistically significant reduction (p<0.05) in PTSD symptoms compared to sertraline plus placebo, as measured by the change in the Clinician-Administered PTSD Scale (CAPS-5) total score from baseline to Week 10 (primary endpoint). In Trial 072, while the primary endpoint was not met, reductions in PTSD symptom severity with brexpiprazole in combination with sertraline were consistent with Trials 061 and 071. Improvements were consistently observed across the Clinical Global Impression Severity (CGI-S) scale and the four CAPS-5 clusters of re-experiencing, avoidance, negative cognition/mood and arousal/reactivity symptoms in Trials 061 and 071.1,4 “Only approximately half of people living with PTSD seek treatment, even though it is one of the most common mental health conditions in the United States,” said Lori Davis, M.D., clinical professor of psychiatry in the Department of Psychiatry and Behavioral Neurobiology, University of Alabama School of Medicine. “For the first time, we now have data from a comprehensive clinical trial program that show a combination of medicines can help improve the four symptom clusters of PTSD as defined by the DSM-5.” Across the three randomized trials, the combination of brexpiprazole and sertraline in adult patients with PTSD were generally well-tolerated, and no new safety observations were identified. The safety and tolerability results were consistent with the known pro brexpiprazole in its approved indications and what has been observed in other clinical trials. The overall incidence of treatment-emergent adverse events (TEAEs) across the three trials was 55.5 percent with brexpiprazole plus sertraline, and 56.2 percent with sertraline plus placebo.2 In Trial 061, the least squares mean change from randomization (Week 1) in CAPS-5 total score was -16.4 with brexpiprazole in combination with sertraline (p=0.011 versus sertraline plus placebo), -12.2 with brexpiprazole plus placebo, -11.4 with sertraline plus placebo, and -10.5 with placebo. In Trial 071, the least squares mean change was -19.2 with brexpiprazole in combination with sertraline (p=0.0007 versus sertraline plus placebo) and -13.6 with sertraline plus placebo. In Trial 072, the least mean change was -16.5 with brexpiprazole 2 mg/day in combination with sertraline (p=0.52 versus sertraline plus placebo), -18.3 with brexpiprazole 3 mg/day in combination with sertraline (p=0.66 versus sertraline plus placebo), and -17.6 with sertraline plus placebo.1 “Lack of recognition and misdiagnosis of PTSD can result in ineffective management, with the average time from onset of symptoms to treatment being 12 years,” said John Kraus, M.D., Ph.D., executive vice president and chief medical officer, Otsuka. “These findings represent a remarkable advancement in managing the PTSD symptoms of those affected by this chronically misunderstood and prevalent psychiatric disorder.” “With approximately 13 million people in the U.S. suffering from PTSD in a given year, these data are crucial to bringing forward a potential new treatment option,” said Johan Luthman, Ph.D., executive vice president, Lundbeck research & development. “We’re hopeful that brexpiprazole in combination with sertraline can become an approved treatment option for appropriate patients living with PTSD.” About CAPS-5 The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) is a structured interview designed to assess PTSD diagnostic status and symptoms severity as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The interview consists of 30 items, with a higher score indicating a worse outcome.4 About Post-Traumatic Stress Disorder PTSD is one of the most common mental health disorders in the United States, with approximately five percent of the population affected during a given year.5,6,9-11 It may occur in people who have experienced or witnessed a traumatic event, series of events or set of circumstances. An individual may experience this as emotionally or physically harmful or life-threatening and may affect mental, physical, social, and/or spiritual well-being. Examples include physical/sexual assault, natural disasters, serious accidents, terrorist acts, war/combat, historical trauma, intimate partner violence and bullying.7,12 Symptoms of PTSD are generally grouped into four types: intrusion (re-experiencing), avoidance, negative cognitions and mood, and marked alterations in arousal and reactivity.5,8 Symptoms can vary over time or vary from person to person.7 Symptoms usually begin within 3 months of the traumatic incident, but they sometimes emerge later. To meet the criteria for PTSD diagnosis, symptoms must last longer than one month, and they must be severe enough to interfere with aspects of daily life, such as relationships or work. Symptoms also must not be due to medications, substance use, or a medical condition.5 Guideline recommended first-line treatment includes psychotherapy (e.g., cognitive behavioral therapy) and first line pharmacotherapy options include certain antidepressants.13 About the Studies Trials 331-201-061 (NCT03033069), 331-201-00071 (NCT04124614) and 331-201-00072 (NCT04174170) were designed to evaluate the efficacy, safety and tolerability of treatment with brexpiprazole in combination with sertraline in adults with PTSD. The trial populations included male and female patients, aged 18-65 years (inclusive), with a diagnosis of PTSD according to the DSM-5 and confirmed by the Mini International Neuropsychiatric Interview. The trials consisted of a 1-week double-blind placebo run-in period followed by 11 weeks of double-blind randomized treatment for a continuous 12-week double-blind treatment period with a 21-day follow-up. Trial 331-201-061 was a 4-arm, double-blind, flexible-dose trial in which patients were randomized to receive flexible-dose brexpiprazole 1-3 mg/day plus sertraline 100-200 mg/day, flexible-dose brexpiprazole 1-3 mg/day plus placebo, flexible-dose sertraline 100-200 mg/day plus placebo, or placebo (double dummy) during the 11-week randomized treatment period. Trial 331-201-00071 was a 2-arm, double-blind, flexible-dose trial in which patients were randomized to receive either flexible-dose brexpiprazole 2-3 mg/day plus sertraline 150 mg/day or sertraline 150 mg/day plus placebo during the 11-week randomized treatment period. Trial 331-201-00072 was a 3-arm, double-blind, fixed-dose trial in which patients were randomized to receive either fixed-dose brexpiprazole 2 mg/day plus sertraline 150 mg/day, brexpiprazole 3 mg/day plus sertraline 150 mg/day, or sertraline 150 mg/day plus placebo during the 11-week randomized treatment period. The primary outcome in all trials was the change from randomization to week 10 in the CAPS-5 total score; in Trials 331-201-00071 and 331-201-00072 patients had to meet blinded criteria at the week 1 visit of the trial.4 About Brexpiprazole Brexpiprazole was approved in the U.S. in 2015, as an adjunctive therapy to antidepressants in adults with MDD and as a treatment for schizophrenia in adults. Most recently, brexpiprazole was approved in the U.S. for the treatment of agitation associated with dementia due to Alzheimer's disease, in May 2023. Brexpiprazole was also approved by Health Canada for schizophrenia and adjunctive treatment of MDD in 2017 and 2019, respectively. It was approved by the Ministry of Health, Labour and Welfare in Japan and by the European Medicines Agency in 2018 for the treatment of schizophrenia.3 Brexpiprazole was discovered by Otsuka and is being co-developed by Otsuka and Lundbeck. The mechanism of action of brexpiprazole is unknown. Brexpiprazole has high receptor binding affinity to norepinephrine, serotonin and dopamine receptors. It is an antagonist at norepinephrine α1B and α2C receptors and serotonin 5-HT2A receptors, as well as a partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors.14,15 INDICATIONS and IMPORTANT SAFETY INFORMATION for REXULTI® (brexpiprazole) INDICATIONS: REXULTI is a prescription medicine used to treat: Major depressive disorder (MDD): REXULTI is used with antidepressant medicines, when your healthcare provider determines that an antidepressant alone is not enough to treat your depression. Schizophrenia It is not known if REXULTI is safe and effective in people under 18 years of age.

Medicines like REXULTI can raise the risk of death in elderly who have lost touch with reality (psychosis) due to confusion and memory loss (dementia). REXULTI is not approved for the treatment of patients with dementia-related psychosis. Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment. Depression and other serious mental illnesses are the most important causes of suicidal thoughts or actions. Some people may have a particularly high risk of having suicidal thoughts or actions. Patients on antidepressants and their families or caregivers should watch for new or worsening depression symptoms, especially sudden changes in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed. Report any changes in these symptoms immediately to the doctor. REXULTI is not approved for the treatment of people younger than 18 years of age. Contraindication: Do not take REXULTI if you are allergic to brexpiprazole or any of the ingredients in REXULTI.
