Enrichment using speech latencies improves treatment effect size in a clinical trial of bipolar depression

Article

Author: Opler, Mark ; Siegel, Joshua S ; Szabo, Steven T ; Cohen, Alex S ; Tomioka, Sasagu ; Hopkins, Seth ; Kirkpatrick, Brian

Clinical trials in depression lack objective measures. Speech latencies are an objective measure of psychomotor slowing with face validity and empirical support. 'Turn latency' is the response time between speakers. Retrospective analysis was carried-out on the utility of turn latencies as an enrichment tool in a clinical trial of bipolar I depression. Speech data was obtained from 274 participants during 1,352 Montgomery-Åsberg Depression Rating Scale (MADRS) recordings in a randomized, placebo controlled, 6-week clinical trial of SEP-4199 (200 mg or 400 mg). Post-randomization turn latencies were compared between patients with moderate to severe depression and patients whose depression had remitted. A cutoff was determined and applied to turn latencies pre-randomization to classify individuals into two groups: Speech Latencies Slow (SL-Slow) and Speech Latencies Normal (SL-Normal). At week 6, SL-Slow (N = 172) showed significant separation in MADRS scores between placebo and treatment arms. SL-Normal (N = 102) showed larger MADRS improvements and no significant separation between placebo and treatment arms. Excluding SL-Normal increased primary outcome effect size by 52 % and 100 % for the treatment arms. Turn latencies are an objective measure available from standard clinical assessments and may assess the severity of symptoms more accurately and screen out placebo responders.

A clinical trial inclusion criteria to enrich for patients presenting with canonical symptom structure in bipolar depression

Article

Author: Szabo, Steven T ; Tomioka, Sasagu ; Hopkins, Seth C ; Koblan, Kenneth S

Clinical drug development in psychiatry is challenging due to heterogeneous patient populations and the uncertainty of measuring neuropsychiatric constructs with symptom rating scales. Here we describe the development and implementation of an enrichment algorithm that identifies canonical versus anomalous symptom presentations, at the individual subject level, based on MADRS ratings obtained at screening and baseline. Data from 5 randomized, placebo-controlled, phase 3 trials in bipolar I disorder was used (N = 2026 subjects and 15,239 MADRS assessments). A variance-covariance difference (VCD) vector was developed to encode individual symptom structure using the 10 items of MADRS from the two sequential assessments. An anomaly score, calculated from each subject's VCD vector was derived by isolation forest to quantify the degree of disparity from the hypothesized canonical item structure. A retrospective application of the algorithm reliably identified a threshold anomaly score above which the psychometric properties of MADRS deteriorate. Consistent with increasing the certainty of MADRS ratings, subjects with a canonical symptom structure at baseline demonstrated greater effect sizes post-baseline in a phase 2 placebo-controlled trial of non-racemic amisulpride (SEP-4199) for bipolar depression, analyzed retrospectively. Our analyses show that the developed algorithm can reduce the symptom structure heterogeneity at baseline and thus improve the measurement certainty of psychiatric symptoms in clinical trials. This novel enrichment method has been prospectively implemented in a Phase 3 clinical study of SEP-4199 and is consistent with regulatory guidelines aimed at increasing the statistical power and lowering patient-burden in clinical trials.

Nonracemic amisulpride (SEP‐4199) is an investigational 85:15 ratio of aramisulpride to esamisulpride and currently in clinical trials for the treatment of bipolar depression. During testing of SEP‐4199, a pharmacokinetic/pharmacodynamic (PK/PD) disconnect was discovered that prompted the development of a controlled‐release (CR) formulation with improved therapeutic index for QT prolongation. Observations that supported the development of a CR formulation included (i) plasma concentrations of amisulpride enantiomers were cleared within 24‐hours, but brain dopamine D2 receptor (D2R) occupancies, although achieving stable levels during this time, required 5 days to return to baseline; (ii) nonracemic amisulpride administered to non‐human primates produced significantly greater D2R occupancies during a gradual 6‐hour administration compared with a single bolus; (iii) concentration–occupancy curves were left‐shifted in humans when nonracemic amisulpride was gradually administered over 3 and 6 hours compared with immediate delivery; (iv) CR solid oral dose formulations of nonracemic amisulpride were able to slow drug dissolution in vitro and reduce peak plasma exposures in vivo in human subjects. By mathematically solving for a drug distribution step into an effect compartment, and for binding to target receptors, the discovery of a novel PK/PD model (termed here as Distribution Model) accounted for hysteresis between plasma and brain, a lack of receptor saturation, and an absence of accumulation of drug occupancy with daily doses. The PK/PD disconnect solved by the Distribution Model provided model‐informed drug development to continue in Phase III using the non‐bioequivalent CR formulation with diminished QT prolongation as dose‐equivalent to the immediate release (IR) formulation utilized in Phase II.

Schizophrenia Market: RISVAN's Approval Has Sparked a Competitive Race Among Pharmaceutical Companies | DelveInsight

The recent approval of Rovi Pharmaceuticals Laboratories' OKEDI/RISVAN (risperidone ISM) has spiked the competition among the other pharmaceutical companies that are developing novel therapies to improve the treatment landscape. RISVAN has the potential to become a blockbuster drug. LAS VEGAS, Aug. 26, 2024 /PRNewswire/ -- Schizophrenia is a severe mental illness affecting about 1% of Americans, cognitive functions, emotional responses, decision-making, and social interaction. Onset typically occurs in late teens to early 20s for men and late 20s to early 30s for women. Currently, as per the WHO, the vast majority of schizophrenia patients around the world are not receiving mental health care. Approximately 50% of people in mental hospitals have a schizophrenia diagnosis, and only 31.3% of people with psychosis receive specialist mental health care. As per DelveInsight analysis, in 2023 the total diagnosed prevalent cases of schizophrenia in the 7MM were found to be approximately 4 million cases out of which the US accounted for nearly 1.5 million cases. It is anticipated that these numbers will rise by 2034 due to several factors, including population growth, improved diagnostic techniques, increased awareness, and reduced stigma around mental health issues prompting more individuals to seek diagnosis, and potentially, environmental stressors contributing to a higher occurrence of the disorder. Schizophrenia treatment involves a blend of medication, psychological counseling, and social support. However, nearly one-third of patients do not respond sufficiently to standard treatments. Relapses, characterized by psychotic symptoms and functional impairments, are significant. Schizophrenia treatment mainly consists of antipsychotic medications that target dopamine neurotransmitters. Second-generation medications are favored because they lower the risk of severe side effects. Long-acting injectable antipsychotics can enhance adherence and improve treatment outcomes. High-dose regimens of specific medications may be advantageous for patients with severe, treatment-resistant schizophrenia. Additionally, hospitalization and electroconvulsive therapy might be necessary for patients who do not respond to medication therapy or during severe episodes. First-generation antipsychotics like chlorpromazine, fluphenazine, haloperidol, and perphenazine are effective in treating positive symptoms such as hallucinations and delusions but do not alleviate negative symptoms or cognitive impairments. Second-generation antipsychotics, including REXULTI/RXULTI (brexpiprazole), CAPLYTA (lumateperone), LATUDA (lurasidone hydrochloride), SAPHRIS (asenapine), ABILIFY MYCITE (aripiprazole tablets with sensor), VRAYLAR/REAGILA (cariprazine), SECUADO (asenapine), INVEGA SUSTENNA/TRINZA/HAYFERA (paliperidone palmitate), ARISTADA/ARISTADA INITIO (aripiprazole lauroxil), PERSERIS (risperidone), FANAPT (iloperidone), and LYBALVI (olanzapine and samidorphan), were developed to address both positive and negative symptoms, as well as cognitive symptoms. Although these medications typically have fewer extrapyramidal side effects, they can cause weight gain, sexual dysfunction, and other metabolic disorders. Additionally, elderly patients using FGAs and SGAs are at an increased risk of developing pneumonia. Learn more about the FDA-approved schizophrenia drugs @ Drugs for Schizophrenia Treatment REXULTI (brexpiprazole) is an oral tablet available in strengths from 0.25 mg to 4 mg, containing various inactive ingredients. While its exact mechanism of action is not fully understood, it work as a partial agonist at serotonin 5-HT1A and dopamine D2 receptors and as an antagonist at serotonin 5-HT2A receptors. REXULTI was first approved in the US in July 2015 for use in adults with MDD and schizophrenia. In January 2022, it received FDA approval for pediatric patients aged 13–17. The EMA approved it in July 2018, and Japan approved it in tablet form in January 2018 and as an oral-disintegrating dose in August 2021. Generic versions of REXULTI have now been approved, which may affect its market presence. Janssen Pharmaceutical's INVEGA SUSTENNA/INVEGA TRINZA/INVEGA HAFYERA (paliperidone palmitate) is an SGA agent that seems to act as a D2 partial agonist and a 5-HT-2A receptor antagonist. INVEGA SUSTENNA is administered monthly, INVEGA TRINZA every three months, and INVEGA HAFYERA twice yearly. Paliperidone is a benzisoxazole derivative. In the EU and Japan, INVEGA SUSTENNA is marketed as XEPLION. In the EU, INVEGA TRINZA is sold as TREVICTA, and in Japan as XEPLION TRI. INVEGA HAFYERA is a long-acting injectable treatment administered in the upper buttocks every six months, providing continuous treatment and symptom control over this period. Additionally, the recent approval of RISVAN (Risperidone ISM) has intensified the competition in the schizophrenia treatment space. Risperidone ISM is a long-acting injectable antipsychotic created and patented by ROVI for treating schizophrenia in adults. From the first injection, it delivers immediate and sustained plasma drug levels without the need for loading doses or additional oral risperidone. This approval is based on the positive outcomes of the pivotal PRISMA-3 study, which assessed the efficacy and safety of Risperidone ISM in patients with schizophrenia. The study's findings demonstrate that the two doses tested (75 mg and 100 mg administered once monthly) successfully met the predetermined primary and secondary efficacy endpoints for treating patients with moderate to severe schizophrenia symptoms. Furthermore, OKEDI (risperidone ISM) was launched in Germany, the UK, and Spain in 2022. The approval was based on the positive results of the pivotal PRISMA-3 study on the efficacy and safety of risperidone ISM in schizophrenia patients. As per the estimates by Delveinsight analysts, this drug has blockbuster potential in the schizophrenia market with medium-fast uptake.

Various potential therapies that are projected to enter during the forecast period include Boehringer Ingelheim's Iclepertin (BI-425809), Sumitomo Pharma/Otsuka's Ulotaront (SEP-363856), Reviva Pharmaceuticals' Brilaroxazine (RP5063), Minerva Neurosciences/Mitsubishi Tanabe Pharma's Roluperidone (MIN-101/MT-210), Karuna Therapeutics (Bristol Myers Squibb)/Royalty Pharma's KarXT (xanomeline-trospium), ACADIA Pharmaceuticals' NUPLAZID (pimavanserin), Teva Pharmaceutical/MedinCell/Royalty Pharma's Olanzapine LAI (mdc-TJK/TV-44749), Neurocrine Biosciences/Mitsubishi Tanabe Pharma's Valbenazine (NBI-98854), Lyndra Therapeutics' LYN-005 (long-acting oral risperidone), Newron Pharmaceuticals' Evenamide (NW-3509), Luye Pharma's LY03010 (ER paliperidone palmitate), and others. Discover which therapies are expected to grab major schizophrenia market share @ Schizophrenia Market Report Iclepertin (BI 425809) is an investigational drug and a glycine transporter 1 (GlyT1) inhibitor aimed at addressing the brain biology related to cognitive symptoms in schizophrenia (CIAS). Abnormalities in glutamatergic signaling downstream of neuronal NMDA receptors contribute to cognitive impairment in this condition. Enhancing NMDA receptor function could potentially improve synaptic plasticity and cognition. Glycine, an essential NMDA receptor co-agonist, is modulated by glycine transporters GlyT-1 and GlyT-2, which are located in presynaptic and astrocyte membranes. These transporters regulate glycine levels by taking it up into nerve terminals and adjacent glial cells, affecting synaptic cleft glycine concentration. By inhibiting these transporters, BI 425809 aims to increase glycine levels, thereby modulating NMDA receptor function. Administered orally, this potent and selective GlyT1 inhibitor is also under investigation for Alzheimer's disease. However, early 2020 Phase II trial results did not support its continued development for this indication, and the focus has now shifted to schizophrenia, with multiple Phase III trials currently underway. Since schizophrenia, patients frequently ignore certain symptoms, such as cognitive impairment. Therefore, if approved, BI-425809 will be the first approved pharmacotherapy for the treatment of CIAS. Ulotaront (SEP-363856), developed by Sumitomo Pharma and Otsuka Pharmaceuticals, is a trace amine-associated receptor 1 (TAAR1) agonist with serotonin 5-HT1A agonist activity. It is a small-molecule oral agent that does not bind to dopamine D2 or serotonin 5-HT2A receptors. Sunovion discovered Ulotaront in collaboration with PsychoGenics using the in vivo phenotypic SmartCube platform and associated artificial intelligence algorithms. Ulotaront is currently in late-stage development for schizophrenia and generalized anxiety disorder (GAD) in Japan and as an adjunctive treatment for major depressive disorder, schizophrenia, and GAD in the US. Top-line results from Phase III DIAMOND 1 and DIAMOND 2 trials in schizophrenia have been released, but the Phase III DIAMOND 3 trial in the US has been halted. Sumitomo Pharma has also stopped a Phase III trial for schizophrenia in Japan and another Phase II/III trial in China, Japan, Taiwan, and the Philippines, citing business strategy reasons. Despite this, two Phase III trials are still ongoing. Recently, Otsuka and Sumitomo revised their licensing agreement, excluding SEP-4199 and SEP-378614. Under this revision, Otsuka gained exclusive rights from SMPA to develop, manufacture, and commercialize ulotaront worldwide. If Otsuka successfully develops and commercializes ulotaront, they will pay up to 30 million USD (approximately 4.5 billion yen) in milestones, along with royalties based on sales, without any upfront payment. Starting January 2024, Otsuka will cover the full cost of studies conducted by both Sumitomo Pharma Group and Otsuka, except for certain studies. KarXT (xanomeline–trospium) is an oral modulator targeting muscarinic receptors found in both the central nervous system (CNS) and various peripheral tissues. This proprietary product combines xanomeline, a novel muscarinic agonist, with trospium, an approved muscarinic antagonist, to preferentially stimulate muscarinic receptors in the CNS. As a dual M1/M4 muscarinic acetylcholine receptor agonist, KarXT aims to improve the positive, negative, and cognitive symptoms of schizophrenia. The US FDA has accepted Karuna Therapeutics' NDA for KarXT for adult schizophrenia treatment, with a PDUFA date of September 26, 2024. Additionally, KarXT is undergoing multiple Phase III trials as an adjunctive treatment with standard-of-care agents for schizophrenia and is being evaluated for psychosis treatment in Alzheimer's disease patients. Following Bristol Myers Squibb's acquisition of Karuna Therapeutics, Karuna is now a wholly-owned subsidiary of BMS. At the Annual Congress of the Schizophrenia International Research Society (SIRS) in April 2024 in Italy, BMS presented promising results from the latest interim analysis of the Phase III EMERGENT-4 open-label extension trial, showing KarXT's efficacy in reducing symptoms in adults with schizophrenia. BMS plans to continue discussions with the US FDA and will release more data from the EMERGENT program later this year.

Sumitomo, Otsuka’s Schizophrenia Candidate Fails Phase III Trials

Pictured: Woman in mental anguish/iStock, Marina Demeshko Sumitomo Pharma and Otsuka Pharmaceutical announced Monday that two Phase III studies of ulotaront failed to meet primary endpoints for acutely psychotic adults living with schizophrenia. The studies, DIAMOND 1 and DIAMOND 2, pitted the trace amine-associated receptor 1 (TAAR1) agonist against a placebo. After six weeks, the studies showed improvement on the Positive and Negative Syndrome Scale (PANSS), but results were not superior to placebo. A “large placebo effect” was present in both studies “which may have masked the molecule’s therapeutic effect,” according to the press release. While placebo responses are frequently higher in psychiatric studies, Sumitomo CEO Hiroshi Nomura pointed to COVID-19 as a potential culprit for the high placebo effect as the studies were conducted throughout the pandemic. The molecule was part of a four-compound deal forged between Otsuka and Sunovion, a subsidiary of Sumitomo, nearly two years ago. The former made an upfront payment of $270 million to the latter with another $620 million on the line in milestone payments. Ulotaront is also in Phase II/III clinical studies as an adjunctive treatment for major depressive disorder as well as generalized anxiety disorder. Another asset from the deal, SEP-4199, is in a Phase III study for bipolar I depression. The TAAR1 agonist was safe and well-tolerated in both schizophrenia studies. The companies plan to further analyze the data and discuss next steps with the FDA, who had already granted Breakthrough Therapy Designation to ulotaront for a schizophrenia indication. Hopes had been high for ulotaront for its potential to treat both the positive psychosis symptoms in addition to the elusive negative symptoms of schizophrenia. Negative symptoms essentially zap patients of their motivation and zeal for life, affecting their ability to function normally. Recently, Roche had to axe a second Phase II trial of its investigational schizophrenia drug ralmitaront, leaving the future of its program uncertain. “In a preliminary analysis, the primary endpoint was negative, and ongoing portions of the study have therefore been discontinued,” said an update on the second Phase II trial posted to the ClinicalTrials.gov website. Karuna Therapeutics’ combination drug, KarXT, appears to treat both positive and negative symptoms of schizophrenia. It has not been specifically tested for negative symptoms. Since the drug is a non-dopamine D2 receptor antagonist, it does not cause many of the typical side effects of schizophrenia medicines like sedation and weight gain. An NDA is anticipated for the investigational M1/M4-preferring muscarinic agonist by the middle of this year. If approved, KarXT will be the first new class of drug for schizophrenia in over 50 years. Sumitomo Pharma’s stock dropped about 10% in Monday trading on the news.

Sunovion and Otsuka Initiate Phase 3 Clinical Development of Non-Racemic Amisulpride for the Treatment of People with Bipolar Depression

Sunovion Pharmaceuticals Inc. (Sunovion) and Otsuka Pharmaceutical Development & Commercialization, Inc. (Otsuka) today announced that the first patient has been randomized in SEP380-301, a Phase 3 clinical study evaluating non-racemic amisulpride (SEP-4199) for the treatment of major depressive episodes associated with bipolar I disorder (bipolar depression). Non-racemic amisulpride is being jointly developed and commercialized as part of a collaboration between Sunovion, its parent company Sumitomo Dainippon Pharma and Otsuka Pharmaceutical Co., Ltd. SEP380-301, named RELEASE 1 (NCT05169710), is a six-week, global, multicenter, randomized, double-blind, placebo-controlled, parallel-group study examining the efficacy, safety and tolerability of non-racemic amisulpride in adults with bipolar depression. Patients will be randomized to receive fixed-dose, non-racemic amisulpride (200 or 400 mg/day) or placebo. The primary endpoint for RELEASE 1 is the reduction of depressive symptoms, as measured by the change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score, compared to placebo, after six weeks of treatment. Following participation in the six-week study period, patients who complete RELEASE 1 may enroll in RELEASE 3 (SEP380-303; NCT05227209), a 12-month, open-label extension study assessing the long-term safety, tolerability and effectiveness of non-racemic amisulpride. “Major depressive episodes associated with bipolar I disorder have a profound impact on those living with the condition. Depressive episodes are associated with mood impairment, fatigue, loss of interest in activities or social situations and, in some cases, suicidality,” said Armin Szegedi, M.D., Ph.D., Senior Vice President, Chief Medical Officer at Sunovion. “We are encouraged by our Phase 2 clinical results and look forward to enhancing our understanding of non-racemic amisulpride and its potential to help address unmet needs in the treatment of bipolar depression.” “Randomizing the first patient in the RELEASE Phase 3 clinical development program is a significant step in our collaboration with Sunovion and our shared goal of expanding neuropsychiatric treatment options to patients living with serious mental conditions,” said John Kraus, M.D., Ph.D., Vice President, Clinical Development Therapeutic Head, CNS, Otsuka Pharmaceutical Development & Commercialization, Inc. “Through our collaboration with Sunovion, we hope to advance SEP-4199, which we believe shows promise for the treatment of people with bipolar depression.” About Non-Racemic Amisulpride (SEP-4199) Non-racemic amisulpride (85:15 ratio of aramisulpride to esamisulpride; SEP-4199) is in Phase 3 clinical development for the treatment of major depressive episodes associated with bipolar I disorder (bipolar depression). Non-racemic amisulpride was designed to enhance 5-HT7 receptor antagonist activity and reduce dopamine D2 receptor antagonist activity compared to racemic amisulpride. Lower D2 receptor occupancy associated with non-racemic amisulpride is intended to maintain overall effectiveness for patients with mood disorders, including bipolar depression, while reducing the burden of D2-related side effects, including movement-related symptoms, such as extrapyramidal symptoms (stiffness, rigidity and tremor) and akathisia (restlessness).1 About Bipolar Disorder Bipolar disorder affects approximately 12.6 million individuals in the United States and an estimated 29 million people worldwide.2,3 A person is usually diagnosed with bipolar disorder after experiencing at least one manic/hypomanic episode, with symptoms that are not better explained by another mental health condition, such as schizophrenia.4 Bipolar disorder is characterized by debilitating mood swings, interspersed with periods of stable mood and behavior.5 When individuals with bipolar disorder are experiencing symptoms, most tend to be depressed rather than manic.4 Bipolar disorder is associated with significant impairment in personal and professional relationships, quality of life and ability to function.6 About Sunovion Pharmaceuticals Inc.
