Bipolar Disorder

TOPLINE:

In 2022, nearly 22% of people who died of drug overdose had a non–substance-related mental health disorder (MHD), new data from the Centers for Disease Control and Prevention (CDC) show. Investigators say the findings point to the need for incorporating mental health care in overdose prevention efforts.

METHODOLOGY:

• The study analyzed data from the CDC’s State Unintentional Drug Overdose Reporting System for 2022, covering 43 states and the District of Columbia.
• A total of 63,424 unintentional and undetermined intent drug overdose deaths during 2022 were included; 92.3% had medical examiner or coroner reports.
• MHDs were identified using source documents such as medical records and categorized according to the DSM-5 criteria.
• Potential intervention opportunities within 1 month of death, such as release from institutional settings or emergency department visits, were also analyzed.

TAKEAWAY:

• In 2022, 21.9% of drug overdose deaths involved people with non–substance-related MHDs, most commonly depression (12.9%), anxiety (9.4%), and bipolar disorder (5.9%).
• Opioids were involved in 82.2% of overdose deaths, with fentanyl or its analogs present in 75.2% of cases.
• Decedents with MHDs had higher usage rates of antidepressants (9.7% vs 3.3%), benzodiazepines (15.3% vs 8.5%), and prescription opioids (16% vs 11.6%) compared with those without MHDs.
• About 24.5% of decedents with MHDs had at least one potential intervention opportunity within 1 month of death, compared with 14.6% of those without MHDs, most commonly release from an institutional setting, treatment for substance use disorder, emergency department or urgent care visit, and nonfatal overdose.

IN PRACTICE:

“This finding suggests the need to screen for SUDs [ substance use disorders] and other MHDs, which is consistent with US Preventive Services Task Force recommendations for adults in primary care settings, and the need to link and integrate treatments to prevent overdose and improve mental health,” the authors wrote.

SOURCE:

The study was led by Amanda T. Dinwiddie, MPH, Division of Overdose Prevention, National Center for Injury Prevention and Control, Centers for Disease Control and Prevention, Atlanta, Georgia. It was published online on August 29, 2024, in Morbidity and Mortality Weekly Report.

LIMITATIONS:

The findings might not be applicable to the entire US population. MHDs could have been undiagnosed or underreported, possibly leading to underestimation. Additionally, variations in the completeness of source documents could have affected the accuracy of identifying MHDs. Data on current or recent mental health treatment were also unavailable. Lastly, substance use disorders may have been recorded as MHDs when not specified.

DISCLOSURES:

The study funding source was not reported. The authors did not disclose any conflicts of interest.

New research provides more evidence that inflammation may contribute to the development of psychiatric disorders and suggests that measuring certain inflammatory biomarkers may aid in the early identification of individuals at high risk.

Using large-scale datasets, researchers found that elevated levels of certain inflammatory biomarkers, particularly leukocytes, haptoglobin, and C-reactive protein (CRP), and lower levels of anti-inflammatory immunoglobulin G (IgG) were associated with an increased risk for psychiatric disorders. 

Individuals with psychiatric disorders had persistently higher levels of leukocytes and haptoglobin, as well as persistently lower levels of IgG, than controls during the 30 years before diagnosis, which suggest “long-term processes and may aid in the identification of individuals at high risk,” the researchers wrote. 

In addition, a higher level of leukocytes was consistently associated with increased odds of depression across different methods of Mendelian randomization (MR) analysis, “indicating a possible causal relationship between leukocytes and depression,” they said. 

The study, with first author Yu Zeng, MSc, with the Mental Health Center and West China Biomedical Big Data Center, West China Hospital, Sichuan University, Chengdu, China, was published online on August 21 in JAMA Psychiatry. 
 

Inflammatory Phenotype

Individuals with psychiatric disorders have been found to have elevated levels of inflammatory biomarkers, but prospective evidence is limited regarding the association between inflammatory biomarkers and subsequent psychiatric disorders risk. 

To investigate further, the researchers employed a “triangulation” approach consisting of an exploration dataset of 585,279 adults in the Swedish AMORIS cohort with no prior psychiatric diagnoses and a measurement of at least one inflammatory biomarker, a validation dataset of 485,620 UK Biobank participants, and genetic and MR analyses using genome-wide association study summary statistics.

In the AMORIS cohort, individuals with a higher than median level of leukocytes (hazard ratio [HR], 1.11), haptoglobin (HR, 1.13), or CRP (HR, 1.02) had an elevated risk for any psychiatric disorder. In contrast, there was an inverse association for IgG level (HR, 0.92). 

“The estimates were comparable for depression, anxiety, and stress-related disorders, specifically, and these results were largely validated in the UK Biobank,” the authors reported. 

In trajectory analyses, compared with controls, individuals with psychiatric disorders had higher leukocyte and haptoglobin levels and lower IgG up to three decades before being diagnosed. 

The MR analysis suggested a possible causal relationship between leukocytes and depression. 

The underlying mechanisms for the associations of serum leukocytes, haptoglobin, CRP, and IgG with psychiatry disorders remain unclear.

“Possible explanations mainly include blood-brain barrier disruption, microglia activation, neurotransmission impairment, and other interactions between inflammations and neuropathology,” the researchers wrote. 

A related paper published online on August 21 in JAMA Psychiatry looked at trajectories of inflammation in childhood and risk for mental and cardiometabolic disorders in adulthood. 

This longitudinal cohort study found that having persistently raised levels of inflammation as measured by CRP throughout childhood and adolescence, peaking at age 9 years, were associated with an increased risk of developing psychosis disorder, severe depression, and higher levels of insulin resistance.
 

Support for Precision Psychiatry

This study is “another strong indication that inflammation plays a role in depression,” Andrew H. Miller, MD, professor of psychiatry and behavioral sciences and director of the behavioral immunology program, Emory University School of Medicine, Atlanta, Georgia, who wasn’t involved in the study, told this news organization. 

“The work adds to the mounting data that there exists an inflammatory phenotype of depression that may uniquely respond to treatment and may have a unique trajectory,” Dr. Miller said. 

“Eventually the field will want to embrace this novel phenotype and better understand how to recognize it and treat it. This is our entrée into precision psychiatry where we identify the right treatment for the right patient at the right time based on an understanding of the underlying cause of their illness,” Dr. Miller added. 

Also weighing in, Alexander B. Niculescu III, MD, PhD, professor of psychiatry and medical neuroscience, Indiana University School of Medicine, Indianapolis, cautioned that these biomarkers are “very nonspecific and are likely related to these subjects that go on to develop psychiatric disorders having more stressful, adverse life trajectories.”

“There are better, more specific blood biomarkers for psychiatric disorders already available,” Dr. Niculescu told this news organization.

His group recently reported that a panel of blood-based biomarkers can distinguish between depression and bipolar disorder, predict a person’s future risk for these disorders, and inform more tailored medication choices. 

Notably, they observed a strong circadian clock gene component to mood disorders, which helps explain why some patients’ conditions become worse with seasonal changes. It also explains the sleep alterations that occur among patients with mood disorders, they said.

This study had no commercial funding. Yu Zeng and Dr. Miller had no relevant disclosures. Dr. Niculescu is a cofounder of MindX Sciences and is listed as inventor on a patent application filed by Indiana University.

An accelerated schedule of intermittent theta burst transcranial magnetic stimulation (aiTBS) completed in less than a week is effective for treatment-resistant bipolar depression, the results of a small randomized controlled trial showed.

Investigators found those who received active aiTBS had a substantial decrease in depressive symptoms compared with those who received sham stimulation.

“aiTBS offers a new potential therapy for depressed patients with bipolar disorder who may not respond well to drugs or cannot tolerate their side effects while also significantly shortening the treatment window,” lead researcher Yvette Sheline, MD, director of the Center for Neuromodulation in Depression and Stress at the University of Pennsylvania, Philadelphia, said in a news release.

The study was published online in JAMA Psychiatry.
 

Remission After 5 Days

The Food and Drug Administration (FDA) cleared aiTBS to treat major depressive disorder. However, the treatment is not yet approved for bipolar depression.

The investigators assessed the effectiveness of aiTBS in 12 men and 12 women (mean age, 43 years) with treatment-resistant bipolar disorder. All participants were on mood stabilizers for at least 4 weeks and had Montgomery-Åsberg Depression Rating Scale (MADRS) scores of 20 or greater.

Of the 24 participants, 22 had a diagnosis of bipolar II disorder. Over 5 days, participants were randomized to receive, on a 1:1 basis, 10 sessions per day of imaging-guided active aiTBS or sham aiTBS over the left dorsolateral prefrontal cortex. Each session lasted for 1 hour. All 24 participants completed the assigned treatment and 1-month follow-up.

Active aiTBS was significantly more effective than sham stimulation in relieving depressive symptoms.

In the active treatment group, MADRS scores dropped from a mean of 30.4 at baseline to 10.5 after treatment. In contrast, the sham group experienced a minor change in MADRS scores, which decreased from a mean of 28.0 at baseline to 25.3 posttreatment.

After 5 days of treatment, half of the participants in the active aiTBS group were in remission, compared with none in the sham group.

The results demonstrate the “clinical efficacy and a short time to achieve improvement in this difficult-to-treat condition. The effect was seen even though the participant sample had high depression severity and treatment resistance, both associated with poor response,” the investigators noted.

Dr. Sheline said there were no differences between active and sham stimulation in the “expected adverse events of headache and dizziness. There were no incidences of manic “flip,” and the Young Mania Rating Scale scores were stable in both active and sham groups with no difference between them.”

The researchers noted that the “large effect size” of active aiTBS could be caused by several factors, including optimized stimulation targeting, accelerated time course, and high pulse number (18,000 per day, 90,000 total).

Future studies are needed to examine the relative contributions of the different protocol components to optimize and personalize treatment and evaluate the durability of the antidepressant effects of aiTBS, they added.
 

A Revolutionary Approach

For comment on the study, we reached out to Nolan Williams, MD, associate professor of psychiatry and behavioral sciences at Stanford University and director of the Stanford Brain Stimulation Lab, Stanford, California.

His laboratory pioneered the Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), which was cleared by the FDA in 2022 for treatment-resistant depression.

Dr. Williams noted that the stimulation and targeting approach used in the current study “mirrors most aspects of the SAINT protocol with very similar results.”

“It’s exciting that we see this kind of pseudo-replication essentially of our work and is supportive of the general view that this approach is revolutionary in its ability to treat people quickly and have such a dramatic clinical effect,” said Dr. Williams.

In March 2024, Dr. Williams and colleagues reported the results of a pilot study of SAINT for bipolar depression, which demonstrated antidepressant efficacy akin to what was observed in the unipolar depression population.

Dr. Williams said, in his experience, the accelerated treatment protocol is convenient and well-liked by patients and, in general, is where the field of psychiatric treatment is headed.

“A general theme that we see in depression and psychiatry is that patients no longer accept long time frames for treatment as being the norm. Whether it be ketamine or this or the upcoming psychedelics, rapid-acting treatments that match the level of acuity will be the norm,” Dr. Williams said.

The study was funded by the Milken Institute and the Baszucki Brain Research Fund. The authors have disclosed no conflicts of interest. Dr. Williams is a named inventor on Stanford-owned intellectual property relating to accelerated TMS pulse pattern sequences and neuroimaging-based TMS targeting. He disclosed ties with Otsuka, NeuraWell, Magnus Medical, and Nooma.

In the active treatment group, MADRS scores dropped from a mean of 30.4 at baseline to 10.5 after treatment. In contrast, the sham group experienced a minor change in MADRS scores, which decreased from a mean of 28.0 at baseline to 25.3 posttreatment.

After 5 days of treatment, half of the participants in the active aiTBS group were in remission, compared with none in the sham group.

The results demonstrate the “clinical efficacy and a short time to achieve improvement in this difficult-to-treat condition. The effect was seen even though the participant sample had high depression severity and treatment resistance, both associated with poor response,” the investigators noted.

Dr. Sheline said there were no differences between active and sham stimulation in the “expected adverse events of headache and dizziness. There were no incidences of manic “flip,” and the Young Mania Rating Scale scores were stable in both active and sham groups with no difference between them.”

The researchers noted that the “large effect size” of active aiTBS could be caused by several factors, including optimized stimulation targeting, accelerated time course, and high pulse number (18,000 per day, 90,000 total).

Future studies are needed to examine the relative contributions of the different protocol components to optimize and personalize treatment and evaluate the durability of the antidepressant effects of aiTBS, they added.
 

A Revolutionary Approach

For comment on the study, we reached out to Nolan Williams, MD, associate professor of psychiatry and behavioral sciences at Stanford University and director of the Stanford Brain Stimulation Lab, Stanford, California.

His laboratory pioneered the Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), which was cleared by the FDA in 2022 for treatment-resistant depression.

Dr. Williams noted that the stimulation and targeting approach used in the current study “mirrors most aspects of the SAINT protocol with very similar results.”

“It’s exciting that we see this kind of pseudo-replication essentially of our work and is supportive of the general view that this approach is revolutionary in its ability to treat people quickly and have such a dramatic clinical effect,” said Dr. Williams.

In March 2024, Dr. Williams and colleagues reported the results of a pilot study of SAINT for bipolar depression, which demonstrated antidepressant efficacy akin to what was observed in the unipolar depression population.

Dr. Williams said, in his experience, the accelerated treatment protocol is convenient and well-liked by patients and, in general, is where the field of psychiatric treatment is headed.

“A general theme that we see in depression and psychiatry is that patients no longer accept long time frames for treatment as being the norm. Whether it be ketamine or this or the upcoming psychedelics, rapid-acting treatments that match the level of acuity will be the norm,” Dr. Williams said.

The study was funded by the Milken Institute and the Baszucki Brain Research Fund. The authors have disclosed no conflicts of interest. Dr. Williams is a named inventor on Stanford-owned intellectual property relating to accelerated TMS pulse pattern sequences and neuroimaging-based TMS targeting. He disclosed ties with Otsuka, NeuraWell, Magnus Medical, and Nooma.

Most people experiencing homelessness have mental health disorders, according to a systematic review and meta-analysis.

In an examination of studies that included nearly 50,000 participants, the current prevalence of mental health disorders among people experiencing homelessness was 67% and the lifetime prevalence was 77%.

“The relationship is likely bidirectional, where experiencing homelessness may exacerbate mental health symptoms or where having a mental health disorder may increase an individual’s risk for experiencing homelessness,” lead author Rebecca Barry, PhD, a postdoctoral fellow at the University of Calgary in Calgary, Alberta, Canada, told this news organization. 

“There are also likely stressors that increase both risk for homelessness and risk for developing mental health disorders. This study examines prevalence but does not examine causal relationships,” she said.

The findings were published in JAMA Psychiatry.
 

A Growing Problem 

To determine the current and lifetime prevalence of mental health disorders among the homeless population, the researchers analyzed 85 studies that examined this question in participants aged ≥ 18 years. The review included 48,414 participants, including 11,154 (23%) women and 37,260 (77%) men.

The lifetime prevalence of mental health disorders was significantly higher in men experiencing homelessness (86%) than in women (69%). The most common mental health disorder was substance use disorder (44%), followed by antisocial personality disorder (26%), major depression (19%), bipolar disorder (8%), and schizophrenia (7%).

The prevalence of current and lifetime mental health disorders among the homeless population was higher than that that observed in the general population (13%-15% and 12%-47%, respectively).

The results resembled those of a previous review that estimated that 76% of people experiencing homelessness living in high-income countries have mental health disorders.

“Even though our results are not surprising, they still are drawing attention to this issue because it is a big problem in Canada, the United States, Europe, and other places,” senior author Dallas Seitz, MD, PhD, professor of psychiatry at the University of Calgary’s Cumming School of Medicine, told this news organization. “The problem is concerning, and it’s not getting better. Addiction and mental health problems are becoming more common among people who are homeless.” 

The bottom line is that people need affordable housing and mental health support, said Dr. Seitz. “It’s a housing problem and a health problem, and we need adequate resources to find better ways for those two systems to collaborate. There are public safety concerns, and we have to try and bring services to people experiencing homelessness. You have to come and meet people where they’re at. You have to try and establish a trusting relationship so that we can get people on the path to recovery.”
 

‘It’s Really About Income’ 

Commenting on the findings for this news organization, Stephen Hwang, MD, professor of medicine at the University of Toronto, Toronto, Ontario, Canada, said, “There have been previous studies of this type, but it is good to have an updated one.” Dr. Hwang, who is also chair in Homelessness, Housing, and Health at St. Michael’s Hospital, did not participate in the research. 

The findings must be understood in the proper context, he added. For one thing, grouping together all mental health disorders and giving a single prevalence figure can be misleading. “They are including in that category a diverse group of conditions. Substance use disorder, personality disorder, schizophrenia, and depression are all lumped together. The 67% prevalence seems very high, but it is a combination of many different conditions. I just don’t want people to look at that number and think that this means that everyone is a substance user or everyone has schizophrenia,” said Dr. Hwang. 

Also, some readers might interpret the findings to mean that mental problems are the reason people are homeless, he added. “That would be an incorrect interpretation because what this study is showing is that people with mental health disorders have a higher risk for becoming homeless. It doesn’t mean that it caused their homelessness. What really causes homelessness is a lack of affordable housing,” said Dr. Hwang.

“In a city or community where housing is very expensive, there’s not enough for everyone to be housed, there is a lot of competition for housing, and there’s not enough affordable housing for a number of reasons, we know that people with mental health conditions and substance use disorders will be among the first to lose their housing,” he said.

“It’s really about income. There are many reasons why a person cannot afford housing. So, not being able to earn enough money to afford it because you have a mental health disorder or substance use disorder is a common underlying reason for homelessness.”

Dr. Hwang also pointed out that people with mental illness who can access support, either through family members or through mental health care, and who also have the income to afford such services do not become homeless.

“Schizophrenia is seen in every population of the world at a rate of 1%. But you travel to certain cities and you see people who appear to have schizophrenia wandering the streets, and you go to other cities in the world and you don’t see anyone who looks like they’re homeless and have schizophrenia,” he said. 

“It’s not because there are fewer people with schizophrenia in those cities or countries; it’s because people with schizophrenia are treated differently. The rate of homelessness is determined not by how many people have that condition [eg, schizophrenia] but by how we treat those people and how we set up our society to either support or not support people who have disabilities.”

The study was funded by the Precision Care With Information, Science and Experience – Mental Health grant funded by the Calgary Health Foundation. Dr. Barry is supported by the Harley Hotchkiss Samuel Weiss Postdoctoral Fellowship awarded by the Hotchkiss Brain Institute at the University of Calgary. Dr. Barry reported having no relevant financial relationships. Dr. Seitz reported grants from Calgary Health Foundation during the conduct of the study as well as grants from University Health Foundation, the Canadian Institutes of Health Research, the Public Health Agency of Canada, the Alzheimer’s Association, and the Hotchkiss Brain Institute. He received honoraria for guideline development from the Canadian Coalition for Seniors Mental Health outside the submitted work. Dr. Hwang reported no relevant financial relationships.

The ketogenic diet shows promise in reducing the symptoms of bipolar disorder and schizophrenia and reversing metabolic syndrome, results of a new pilot study show. 

Participants who adhered to the high-fat, low-carb diet experienced a 30% reduction in psychiatric symptoms and an average 10% reduction in weight. 

“We’re seeing huge changes,” first author Shebani Sethi, MD, of Stanford University in Stanford, California said in a press release. “Even if you’re on antipsychotic drugs, we can still reverse the obesity, the metabolic syndrome, and the insulin resistance. I think that’s very encouraging for patients.”

The findings were published online in Psychiatric Research. 
 

Neuroprotective Effect? 

Recent research supports the hypothesis that psychiatric illness may stem, at least in part, from deficits in brain metabolism and that a keto diet may be neuroprotective by reducing inflammation and oxidative stress. 

The pilot study included 21 participants with schizophrenia (n = 5) or bipolar disorder (n = 16) who were aged 18-75 years. All were currently taking psychotropic medications. Participants were overweight (body mass index [BMI] ≥ 25) and had gained more than 5% of their body mass while taking psychotropic medication, or they had at least one metabolic abnormality, such as insulin resistance or dyslipidemia. 

At baseline, participants received a physical and psychiatric evaluation and 1 hour of instruction on how to implement the keto diet, which included 10% carbohydrate, 30% protein, and 60% fat. 

Investigators monitored blood ketone levels at least once a week and defined participants as keto-adherent if their levels were 0.5-5 mM for 80%-100% of the times they were measured.

Health coaches checked in with participants for about 5-10 minutes each week to answer diet-related questions.

Psychiatric assessments, which included mood rating and global functioning scales, were completed at baseline, 2 months, and at the end of the 4-month study. 

The research team tracked participants’ adherence to the diet by weekly measurement of blood ketone levels. 

By the end of the trial, 14 patients had been fully adherent with the diet, six had been semi-adherent, and only one had been nonadherent. Higher ketone levels, suggesting greater adherence, correlated with better metabolic health.

As measured by the Clinical Global Impression-Schizophrenia and Clinical Global Impression for Bipolar Disorder–Overall Severity, participants experienced a 31% reduction in symptom severity (P < .001). Overall, 43% (P < .02) of participants achieved recovery as defined by the Clinical Mood Monitoring Form criteria: 50% of the adherent group and 33% of those who were semi-adherent.
 

Metabolic Benefits

Initially, 29% of participants had metabolic syndrome and more than 85% had co-occurring medical conditions such as obesity, hyperlipidemia, or prediabetes. By the end of the study, none met criteria for metabolic syndrome.

On average, participants experienced a 10% reduction in weight and BMI. Waist circumference was reduced by 11%, fat mass index dropped by 17%, and systolic blood pressure decreased by 6%. In addition, metabolic markers including visceral fat, inflammation, A1c, and insulin resistance also improved. All outcomes were significant at P < .001 except for systolic blood pressure, at P < .005.

There was also a 20% reduction in triglycerides and a 21% increase in low-density lipoprotein cholesterol (both at P < .02). 

The study’s limitations include its small sample size, the lack of control arm, and short duration.

“Mental health and physical health are interconnected and addressing metabolic issues can complement psychiatric treatment to enhance overall well-being. Understanding the

mechanisms and potential synergies between psychiatric treatment and metabolic improvements can also inform the development of more effective interventions,” the researchers wrote. 

The study was funded by the Baszucki Group, Kuen Lau Fund, and the Obesity Treatment Foundation. The authors declare no competing interests.

SYNLAB and ALCEDIAG recently launched the first blood test to assist in mental health diagnosis in France. The test is aimed at differentiating bipolar disorders from depression. The news may be surprising, given the challenges in diagnosing psychiatric conditions, especially when they share common symptoms such as recurrent depression and bipolar disorder.

Psychiatrists’ reactions to the new test are cautious. Many have echoed the sentiments of the French Association of Biological Psychiatry and Neuropsychopharmacology (AFPBN) and Stéphane Jamain, PhD, director of translational neuropsychiatry research (Inserm U955, Mondor Institute of Biomedical Research), who spoke with this news organization.

Early Diagnosis

Depression and bipolar disorders are two distinct psychiatric illnesses requiring different treatments. Early and accurate diagnosis and appropriate treatment are major challenges for clinicians, especially since untreated or inadequately treated bipolar disorder can lead to significant mental and physical health consequences for patients and their families.

Published studies indicate that it takes an average of 8-10 years, and sometimes even longer, to diagnose bipolar disorder. The diagnosis is based on a psychiatric clinical examination, which is conducted by a specialist using validated questionnaires and evaluation scales.

Early and accurate diagnosis of bipolar disorders that allows for appropriate treatment would be a significant advance for patients and their families. This is what the French laboratories SYNLAB, in partnership with ALCEDIAG, propose through myEDIT-B, a blood test described as “the first validated diagnostic aid test to differentiate depression and bipolar disorders.”

Whether this test, the availability of which has somewhat surprised the psychiatric medical and scientific community, will attract psychiatrists remains to be seen.

The AFPBN stated in a press release that “to date, no test meets conditions for clinical use.” For a diagnostic test to be scientifically valid, ethical, and usable in clinical practice, its development must meet strict criteria, as highlighted by the AFPBN. The approximately 10 criteria include the validation of the scientific results in at least two independent clinical studies or cohorts, satisfactory sensitivity (detection of true positives) and specificity (detection of false negatives), and cost that is ethically responsible and allows patient access, independent of commercial interests.

ALCEDIAG has reported two clinical studies, but only one has been published so far (in Translational Psychiatry) involving 400 patients. In this case, “these patients already had a well-established psychiatric condition, did not quite present the same symptoms between patients with recurrent depression and those with bipolar disorder and were not taking the same treatments,” noted Dr. Jamain.

Differentiating between bipolar disorder and depression is crucial, especially regarding treatments, because antidepressants given to a patient with bipolar disorder can induce a manic shift if they are not accompanied by mood stabilizers, Dr. Jamain acknowledged. Nevertheless, he believes that based on what the laboratory has published, it is difficult to comment on the test at this time.

RNA Editing 

Moreover, myEDIT-B is based on a technique that measures RNA editing modifications of specific markers in patients’ blood, which could lead to differences in amino acids within proteins. The technique is unique to the ALCEDIAG laboratory, which coupled it with an artificial intelligence tool that specifically selected 8 RNA sequences for analysis from thousands of edited sequences to obtain a differential signature for unipolar and bipolar depressions. “This method is niche, the trademark of ALCEDIAG,” said Dr. Jamain, who questions the significance of this “editing” on the periphery of the CNS.

“This technique differs from that adopted by most international consortia, which are very active in this research field. The latter technique compares differences in genome [DNA] nucleotides between individuals in large cohorts involving tens of thousands of people and identifies the most frequently occurring patterns associated with a pathology to deduce a risk of developing a psychiatric illness,” said Jamain. “However, the information provided by these large-scale studies does not allow us to define who is at risk for developing the disease any more than the simple observation of the familial recurrence [heritability] of it does.” 

Scientific Validation 

While ALCEDIAG boasts a sensitivity and specificity of more than 80% for its test, the psychiatric world remains cautious. Interviewed by France Info TV, Marion Leboyer, PhD, general director of the FondaMental Foundation, psychiatrist, and researcher (at AP-HP, Inserm in Créteil, France), highlighted the importance of encouraging research on psychiatric illnesses, especially that which will contribute to the understanding and treatment of patients with bipolar disorders. But she expressed caution regarding the test because of the absence of rigorous scientific validation through clinical trials.

Regarding “ALCEDIAG’s test and its commercial aspect, caution is warranted,” said Dr. Jamain. Only time will tell if psychiatrists will prescribe this €899 test, which currently is not reimbursed by social security (see box below). ALCEDIAG plans to submit a validation dossier to the US Food and Drug Administration.

Test Not Reimbursed by Social Security

The ALCEDIAG test will be available beginning in April 2024, by prescription, in SYNLAB France network laboratories. It is intended for patients aged 18 years and older who are being treated for a moderate or severe depressive episode. Test results are transmitted within 4 weeks to the prescribing psychiatrist, who will confirm the diagnosis to the patient during a consultation. Already available in Italy, this in vitro medical device has a CE-IVD marking. In France, however, it costs €899 and is not reimbursed by social security because of insufficient clinical evidence.

SYNLAB and ALCEDIAG recently launched the first blood test to assist in mental health diagnosis in France. The test is aimed at differentiating bipolar disorders from depression. The news may be surprising, given the challenges in diagnosing psychiatric conditions, especially when they share common symptoms such as recurrent depression and bipolar disorder.

Psychiatrists’ reactions to the new test are cautious. Many have echoed the sentiments of the French Association of Biological Psychiatry and Neuropsychopharmacology (AFPBN) and Stéphane Jamain, PhD, director of translational neuropsychiatry research (Inserm U955, Mondor Institute of Biomedical Research), who spoke with this news organization.

Early Diagnosis

Depression and bipolar disorders are two distinct psychiatric illnesses requiring different treatments. Early and accurate diagnosis and appropriate treatment are major challenges for clinicians, especially since untreated or inadequately treated bipolar disorder can lead to significant mental and physical health consequences for patients and their families.

Published studies indicate that it takes an average of 8-10 years, and sometimes even longer, to diagnose bipolar disorder. The diagnosis is based on a psychiatric clinical examination, which is conducted by a specialist using validated questionnaires and evaluation scales.

Bipolar 1 disorder is a chronic and disabling mental health disorder that results in cognitive, functional, and social impairments associated with an increased risk for hospitalization and premature death.

Bipolar 1 disorder is characterized by manic episodes that last for at least 7 days, or manic symptoms that are so severe that they require immediate medical care. Depressive episodes also occur.

Dr Michael Thase, from the University of Pennsylvania, explains that although ongoing treatment is essential to prevent relapse and recurrence, particularly after a hospitalization, adherence can be serious problem.

Long-acting injectable (LAI) agents can act as a bridge between oral medications initiated in hospital and ongoing prevention therapies.

Dr Thase says LAIs can help improve adherence and patient quality of life, and are effective against relapses in adults with bipolar 1 disorder.

Recent research highlights the potential role of an atypical antipsychotic to treat anxiety, a prevalent and undertreated symptom in bipolar I disorder (BPD). Notably, investigators said, the drug comes without the typical metabolic side effects, including weight gain, associated with this drug class.

A post hoc analysis of pooled data from two trials comparing two different doses of cariprazine (Vraylar) to placebo showed it was consistently effective not only in alleviating bipolar depression but also in improving symptoms of anxiety.

“Since this was a post hoc analysis, one has to be careful about not overstating the findings,” said study investigator Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, Toronto, Ontario, Canada, and head of the Mood Disorders Psychopharmacology Unit.

“But what we can say is that anxiety has been an under-researched, undertreated symptom dimension in BPD, and these findings about cariprazine are very promising,” said Dr. McIntyre, chair and executive director of the Brain and Cognition Discovery Foundation, also in Toronto.

The analysis was published in International Clinical Psychopharmacology) and was presented as a poster at the 2023 Neuroscience Education Institute, Colorado Springs, Colorado.
 

Ubiquitous, Common, Hazardous

Anxiety in BPD is “ubiquitous, common, and hazardous,” Dr. McIntyre said. “We talk so much about depression and mania as cardinal presentations, but someone could make a case that in that trifecta, we’re missing anxiety.”

In patients with BPD and anxiety, “the index episode is much more difficult to treat, there’s a longer time to remission, lower rates of recovery, and a shorter time to recurrence,” noted Dr. McIntyre, chair of the board of the Depression and Bipolar Support Alliance.

Anxiety also may “represent a portent of other things that can add more to the trouble, like alcohol, illicit drugs, or cannabis use — especially now that cannabis is no longer illegal,” Dr. McIntyre said.

Unfortunately, he said, “there hasn’t been an organized, systematic approach to developing a therapy for anxiety in BPD.” Rather, patients are prescribed benzodiazepines, gabapentinoids, or selective serotonin reuptake inhibitors, all of which have limitations, he added.

Some atypical antipsychotics such as quetiapine have been shown to be helpful with anxiety but “have a lot of baggage and side effects — especially sedation, somnolence, weight gain, and metabolic problems,” Dr. McIntyre noted.

Cariprazine is a dopamine D3-preferring D3/D2 partial agonist, a serotonin 5-HT1A receptor partial agonist, and 5-HT2B receptor antagonist, which has shown anxiolytic-like activity in rodent models.

It was approved by the US Food and Drug Administration to treat mania, depression, and mixed episodes of BPD in 2015 and BPD in 2019.

Dr. McIntyre and his team believed there was an opportunity in the completed randomized controlled trials of cariprazine in BPD to conduct a post hoc analysis of its impact on anxiety.
 

‘Cornerstone Mood Stabilizer’

The researchers pooled data from two phase 3, randomized, double-blind, placebo-controlled studies in adults with BPD experiencing a current major depressive episode.

The pooled intention-to-treat population consisted of 952 patients with BPD (mean age, ~43 years; 62% female) randomized to receive either 1.5 mg/d, 3 mg/d of cariprazine, or placebo. Patients were divided into two subsets: Lower or higher anxiety (defined as a Hamilton Anxiety Rating Scale [HAM-A] total score of < 18 and ≥ 18, respectively). Patients also completed the Montgomery-Åsberg Rating Scale (MADRS).

A third of the patients received a placebo, a third received the 1.5 mg/d dose, and a third received the 3 mg/d dose. Demographic and baseline characteristics were similar between the subsets.

Results showed there was a statistically significant change in HAM-A total score for cariprazine 1.5 mg/d (P = .0027). The investigators also found a statistically significant change in MADRS total score change for cariprazine 1.5 mg (P = .0200) in the higher anxiety subset. The rate of remission was significantly greater for cariprazine 1.5 mg/d in the higher and lower anxiety subsets (P = .0172 and P = .0004, respectively).

In addition, the change in HAM-A total score change was statistically significant for cariprazine 1.5 mg/d in the higher anxiety subgroup (P = .0105) and the 3 mg/d dose in the lower anxiety subgroup (P = .0441).

Dr. McIntyre hopes these findings can be replicated in other trials.

“Clinically, I find that many patients who take cariprazine don’t require as many benzodiazepines or other medications for anxiety, and it’s one of the better-tolerated medications without metabolic complications or weight gain, so it’s become a cornerstone mood stabilizer,” he said.
 

Polypharmacy Avoided

Another recent study retrospectively analyzed medical records of close to 40 adult patients with BPD I who were receiving treatment with aripiprazole for bipolar depression and then switched to cariprazine.

“We wanted to conduct a study in depressed patients who had gained weight on aripiprazole and then directly switched to cariprazine. It improved their mood and helped mitigate weight gain, thereby avoiding polypharmacy of additional antidepressants and weight loss agents,” said study investigator Maxwell Zachary Price, a medical student at Hackensack Meridian School of Medicine, Nutley, New Jersey.

“In our general outpatient psychiatry practice, we’ve treated many adult patients with oral aripiprazole for maintenance of BPD,” the study’s senior investigator, Richard Price, MD, clinical assistant professor of psychiatry at Weill Cornell Medical College, New York City, added.

Aripiprazole is associated with weight gain. Moreover, aripiprazole “hasn’t shown efficacy in managing BPD,” he said.

Most patients in Dr. Price’s practice are insured through Medicaid, which mandates treatment with aripiprazole before covering cariprazine. “We noticed their weight had been creeping up over the years, and they also were experiencing depressive symptoms,” he said.

The requirement to initiate treatment with aripiprazole before switching to cariprazine offered Dr. Price an opportunity to compare the two agents in this real-world setting by retrospectively reviewing the charts of 37 patients with BPD (23 females and 14 males who made the switch). The patients had been taking aripiprazole for a mean duration of 94.9 weeks and had experienced a mean increase in body weight of 16.1% ± 12.3% on aripiprazole before switching.

Patients who were taking 2 mg-10 mg of aripiprazole were switched to 1.5 mg of cariprazine, while those taking ≥ 15 mg of aripiprazole were switched to 3 mg of cariprazine.

“Patients tolerated the switch well and maintained stability during the transition,” and “no patients discontinued cariprazine during the study,” Dr. Price said.

After a mean duration of 36.7 weeks (range, 1-127 weeks), the patients showed a decrease in Clinical Global Impression-Bipolar Severity of Illness Scale score from a mean of 5.0 ± 0.9 to a mean of 2.8 ± 0.7 (t = −12.75, P < .00001).

The patients’ weight dropped from a mean of 90.3± 21.5 kg on aripiprazole to a mean of 83.9 ± 19.2 kg on cariprazine (t = −4.22, P < .001).

Two patients experienced initial nausea that resolved by taking the medication with food, and two experienced initial restlessness that resolved with dosage reduction.

“We found that the patients were lighter in mood, body habitus and weight, and less agitated and their mental alertness and concentration improved as well,” said Dr. Price. He hopes that further research in randomized blinded trials will corroborate the findings.
 

Hypothesis-Generating Research

Joseph Cerimele, MD, MPH, associate professor of psychiatry and behavioral sciences, University of Washington, Division of Population Health, UW Medicine, Seattle, Washington, said the research findings are “hypothesis-generating.”

Dr. Ciremele, who wasn’t involved with either study, said many clinicians and researchers are trying to tailor treatment options to match patient characteristics, and these studies and other similar research, “help us all ask questions related to concurrent symptoms in bipolar depression.”

However, the post hoc analysis was a secondary analysis of an efficacy trial where individuals with concurrent anxiety disorders were excluded. “So, a next step might be to evaluate this and other treatments in individuals with BPD and concurrent anxiety disorders,” he said.

The study by Jain et al was funded by AbbVie. Dr. McIntyre had received research grant support from CIHR/GACD/National Natural Science Foundation of China and the Milken Institute; speaker/consultation fees from Lundbeck, Janssen, Alkermes, Neumora Therapeutics Inc., Boehringer Ingelheim, Sage, Biogen, Mitsubishi Tanabe, Purdue, Pfizer, Otsuka, Takeda, Neurocrine, Sunovion, Bausch Health, Axsome Therapeutics, Novo Nordisk, Kris, Sanofi, Eisai, Intra-Cellular Therapies, NewBridge Pharmaceuticals, Viatris, Abbvie, and Atai Life Sciences. Dr. McIntyre is the CEO of Braxia Scientific Corp. His coauthors’ disclosures are listed in the original paper. Dr. Price had received honoraria from AbbVie, Alkermes, Allergan, Intra-Cellular Therapies, Janssen, Jazz, Lundbeck, Neuronetics, Otsuka, and Supernus. Mr. Price and Dr. Cerimele reported no relevant financial relationships.

In addition, the change in HAM-A total score change was statistically significant for cariprazine 1.5 mg/d in the higher anxiety subgroup (P = .0105) and the 3 mg/d dose in the lower anxiety subgroup (P = .0441).

Dr. McIntyre hopes these findings can be replicated in other trials.

“Clinically, I find that many patients who take cariprazine don’t require as many benzodiazepines or other medications for anxiety, and it’s one of the better-tolerated medications without metabolic complications or weight gain, so it’s become a cornerstone mood stabilizer,” he said.
 

Polypharmacy Avoided

Another recent study retrospectively analyzed medical records of close to 40 adult patients with BPD I who were receiving treatment with aripiprazole for bipolar depression and then switched to cariprazine.

“We wanted to conduct a study in depressed patients who had gained weight on aripiprazole and then directly switched to cariprazine. It improved their mood and helped mitigate weight gain, thereby avoiding polypharmacy of additional antidepressants and weight loss agents,” said study investigator Maxwell Zachary Price, a medical student at Hackensack Meridian School of Medicine, Nutley, New Jersey.

“In our general outpatient psychiatry practice, we’ve treated many adult patients with oral aripiprazole for maintenance of BPD,” the study’s senior investigator, Richard Price, MD, clinical assistant professor of psychiatry at Weill Cornell Medical College, New York City, added.

Aripiprazole is associated with weight gain. Moreover, aripiprazole “hasn’t shown efficacy in managing BPD,” he said.

Most patients in Dr. Price’s practice are insured through Medicaid, which mandates treatment with aripiprazole before covering cariprazine. “We noticed their weight had been creeping up over the years, and they also were experiencing depressive symptoms,” he said.

The requirement to initiate treatment with aripiprazole before switching to cariprazine offered Dr. Price an opportunity to compare the two agents in this real-world setting by retrospectively reviewing the charts of 37 patients with BPD (23 females and 14 males who made the switch). The patients had been taking aripiprazole for a mean duration of 94.9 weeks and had experienced a mean increase in body weight of 16.1% ± 12.3% on aripiprazole before switching.

Patients who were taking 2 mg-10 mg of aripiprazole were switched to 1.5 mg of cariprazine, while those taking ≥ 15 mg of aripiprazole were switched to 3 mg of cariprazine.

“Patients tolerated the switch well and maintained stability during the transition,” and “no patients discontinued cariprazine during the study,” Dr. Price said.

After a mean duration of 36.7 weeks (range, 1-127 weeks), the patients showed a decrease in Clinical Global Impression-Bipolar Severity of Illness Scale score from a mean of 5.0 ± 0.9 to a mean of 2.8 ± 0.7 (t = −12.75, P < .00001).

The patients’ weight dropped from a mean of 90.3± 21.5 kg on aripiprazole to a mean of 83.9 ± 19.2 kg on cariprazine (t = −4.22, P < .001).

Two patients experienced initial nausea that resolved by taking the medication with food, and two experienced initial restlessness that resolved with dosage reduction.

“We found that the patients were lighter in mood, body habitus and weight, and less agitated and their mental alertness and concentration improved as well,” said Dr. Price. He hopes that further research in randomized blinded trials will corroborate the findings.
 

Hypothesis-Generating Research

Joseph Cerimele, MD, MPH, associate professor of psychiatry and behavioral sciences, University of Washington, Division of Population Health, UW Medicine, Seattle, Washington, said the research findings are “hypothesis-generating.”

Dr. Ciremele, who wasn’t involved with either study, said many clinicians and researchers are trying to tailor treatment options to match patient characteristics, and these studies and other similar research, “help us all ask questions related to concurrent symptoms in bipolar depression.”

However, the post hoc analysis was a secondary analysis of an efficacy trial where individuals with concurrent anxiety disorders were excluded. “So, a next step might be to evaluate this and other treatments in individuals with BPD and concurrent anxiety disorders,” he said.

Recent research highlights the potential role of an atypical antipsychotic to treat anxiety, a prevalent and undertreated symptom in bipolar I disorder (BPD). Notably, investigators said, the drug comes without the typical metabolic side effects, including weight gain, associated with this drug class.

A post hoc analysis of pooled data from two trials comparing two different doses of cariprazine (Vraylar) to placebo showed it was consistently effective not only in alleviating bipolar depression but also in improving symptoms of anxiety.

“Since this was a post hoc analysis, one has to be careful about not overstating the findings,” said study investigator Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, Toronto, Ontario, Canada, and head of the Mood Disorders Psychopharmacology Unit.

“But what we can say is that anxiety has been an under-researched, undertreated symptom dimension in BPD, and these findings about cariprazine are very promising,” said Dr. McIntyre, chair and executive director of the Brain and Cognition Discovery Foundation, also in Toronto.

The analysis was published in International Clinical Psychopharmacology) and was presented as a poster at the 2023 Neuroscience Education Institute, Colorado Springs, Colorado.
 

Ubiquitous, Common, Hazardous

Anxiety in BPD is “ubiquitous, common, and hazardous,” Dr. McIntyre said. “We talk so much about depression and mania as cardinal presentations, but someone could make a case that in that trifecta, we’re missing anxiety.”

In patients with BPD and anxiety, “the index episode is much more difficult to treat, there’s a longer time to remission, lower rates of recovery, and a shorter time to recurrence,” noted Dr. McIntyre, chair of the board of the Depression and Bipolar Support Alliance.

Anxiety also may “represent a portent of other things that can add more to the trouble, like alcohol, illicit drugs, or cannabis use — especially now that cannabis is no longer illegal,” Dr. McIntyre said.

Unfortunately, he said, “there hasn’t been an organized, systematic approach to developing a therapy for anxiety in BPD.” Rather, patients are prescribed benzodiazepines, gabapentinoids, or selective serotonin reuptake inhibitors, all of which have limitations, he added.

Some atypical antipsychotics such as quetiapine have been shown to be helpful with anxiety but “have a lot of baggage and side effects — especially sedation, somnolence, weight gain, and metabolic problems,” Dr. McIntyre noted.

Cariprazine is a dopamine D3-preferring D3/D2 partial agonist, a serotonin 5-HT1A receptor partial agonist, and 5-HT2B receptor antagonist, which has shown anxiolytic-like activity in rodent models.

It was approved by the US Food and Drug Administration to treat mania, depression, and mixed episodes of BPD in 2015 and BPD in 2019.

Dr. McIntyre and his team believed there was an opportunity in the completed randomized controlled trials of cariprazine in BPD to conduct a post hoc analysis of its impact on anxiety.
 

‘Cornerstone Mood Stabilizer’

The researchers pooled data from two phase 3, randomized, double-blind, placebo-controlled studies in adults with BPD experiencing a current major depressive episode.

The pooled intention-to-treat population consisted of 952 patients with BPD (mean age, ~43 years; 62% female) randomized to receive either 1.5 mg/d, 3 mg/d of cariprazine, or placebo. Patients were divided into two subsets: Lower or higher anxiety (defined as a Hamilton Anxiety Rating Scale [HAM-A] total score of < 18 and ≥ 18, respectively). Patients also completed the Montgomery-Åsberg Rating Scale (MADRS).

A third of the patients received a placebo, a third received the 1.5 mg/d dose, and a third received the 3 mg/d dose. Demographic and baseline characteristics were similar between the subsets.

Results showed there was a statistically significant change in HAM-A total score for cariprazine 1.5 mg/d (P = .0027). The investigators also found a statistically significant change in MADRS total score change for cariprazine 1.5 mg (P = .0200) in the higher anxiety subset. The rate of remission was significantly greater for cariprazine 1.5 mg/d in the higher and lower anxiety subsets (P = .0172 and P = .0004, respectively).

In addition, the change in HAM-A total score change was statistically significant for cariprazine 1.5 mg/d in the higher anxiety subgroup (P = .0105) and the 3 mg/d dose in the lower anxiety subgroup (P = .0441).

Dr. McIntyre hopes these findings can be replicated in other trials.

“Clinically, I find that many patients who take cariprazine don’t require as many benzodiazepines or other medications for anxiety, and it’s one of the better-tolerated medications without metabolic complications or weight gain, so it’s become a cornerstone mood stabilizer,” he said.

Iloperidone, a second-generation antipsychotic used to treat schizophrenia, appears to be safe and effective in the treatment of bipolar mania, new research suggested.

Results of the phase 3 randomized double-blind placebo-controlled trial show patients with bipolar mania who received iloperidone had significantly greater change from baseline to 4 weeks on the Young Mania Rating Scale (YMRS) compared with placebo, an improvement detected as early as 14 days from the initial dose.

The incidence of akathisia and extrapyramidal symptoms (EPS) was low in the treatment group, and the medication was well-tolerated.

“This study provides evidence that iloperidone improves the symptoms of bipolar mania in adults and can be a useful treatment option for people with bipolar disorder,” the investigators, led by Rosarelis Torres, PhD, of Vanda Pharmaceuticals, and colleagues wrote.

The study was published online in the Journal of Clinical Psychiatry.
 

Early Improvement

Iloperidone was first approved by the US Food and Drug Administration in 2009 for treatment of schizophrenia.

The current study included 414 participants (mean age, 43 years; 56% male) across 17 US and international sites. Patients with psychotic features received a fixed daily dose of 24 mg of iloperidone (n = 206) or placebo (n = 208).

Participants completed a screening period of up to 7 days before randomization, followed by a 1-day baseline evaluation period and a 28-day treatment phase.

The primary efficacy endpoint was change from baseline to week 4 on the YMRS (vs placebo), while secondary efficacy endpoints included change from baseline on the Clinical Global Impressions-Severity and Clinical Global Impression of Change scales (CGI-S and CGI-C, respectively).

Compared with placebo, iloperidone was associated with significant improvement of mania symptoms at week 4, with a mean reduction on the YMRS scale of −4.0 (P = .000008), and significant decreases on the CGI-S (mean, −0.4; P = .0005) and CGI-C scales (mean, −0.5; P = .0002).

Statistically significant differences between iloperidone and placebo were observed as early as day 14 and continued through days 21 and 28.

Post hoc analyses found no difference in efficacy even when patients who had received benzodiazepines were excluded, regardless of the presence or absence of psychotic features at baseline.
 

Favorable Akathisia Profile

As for safety, 68% of patients in the iloperidone group experienced at least one adverse event, compared with 49% of patients in the placebo group.

Patients in the treatment group had a higher rate of withdrawal from the study than those in the placebo group (32.9% vs 27.1%), and more patients in the iloperidone group experienced treatment-emergent adverse events (TEAEs) leading to study drug discontinuation (8.7% vs 5.3%). However, no TEAEs associated with discontinuation occurred in more than two patients in either group, and none of the participants experienced any AE leading to death.

The most common adverse events (AEs) were tachycardia (18%), dizziness (11%), dry mouth (9%), increased alanine aminotransferase (7%), nasal congestion (6%), weight gain (6%), and somnolence (5%).

Five serious AEs were reported in four participants in the treatment group and one in the placebo group. Two were identified as related to the study medication. These included sedation and spontaneous penile erection.

Changes from baseline in clinical laboratory parameters were not largely different between the groups, but there were post-randomization changes in QT interval in three iloperidone patients. The incidence of orthostatic response was also higher for iloperidone vs placebo.

Although “much improved compared to early antipsychotics, SGAs can still cause considerable adverse motor side effects,” the authors wrote. “However, among all SGAs, iloperidone’s akathisia profile is favorable.”

Antipsychotic-induced akathisia has been reported more frequently in patients with bipolar disorder than in those with schizophrenia treated with the same medication, investigators noted.

One study limitation is the fact that long-term efficacy in the prevention of manic or depressive episodes was not assessed.
 

Potential Second-Line Treatment

Commenting on the study, Richard Louis Price, MD, assistant professor of psychiatry, at Weill Cornell Medical College, New York City, said the findings suggest iloperidone may be “modestly effective” for patients with bipolar 1 mania or mixed episodes.

“It’s helpful to have new treatment options, especially for patients who have difficulty tolerating other agents,” said Dr. Price, who was not involved with the study.

Also commenting on the research, Roger S. McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, Toronto, Ontario, Canada, noted iloperidone’s “interesting antipsychotic pharmacodynamic,” highlighting the drug’s high-binding affinity for serotonin 5HT_2A and dopamine D₂ and D₃ receptors, as well as the noradrenergic α₁ receptors.

The drug’s profile “suggests benefit in manic features and agitation, perhaps with a lower propensity to EPS, which is especially important in persons at higher risk, like persons living with bipolar disorder,” Dr. McIntyre said.

Dr. McIntyre, who was not involved with the study, added iloperidone could be a second-line therapy because of its tolerability profile, provided the study results can be replicated.

“When considering alternatives with similar efficacy, absence of titration (or simple titration) minimal to no weight gain, no orthostatic hypotension, and no potential concerns with QT, those alternatives would have to be considered first-line, assuming that the study results are replicated,” he said.

One dose of synthetic psilocybin in combination with psychotherapy significantly reduces treatment-resistant depression associated with bipolar II disorder (BDII), a small, nonrandomized clinical trial shows. However, the investigators and other outside experts warn these results should not be overinterpreted.

Three weeks after receiving psilocybin and psychotherapy, all 15 participants’ depression scores dropped by an average of 24 points. Twelve met criteria for response and 11 for remission.

This benefit lasted until the 12-week mark, with 12 participants (80%) meeting criteria for both response and remission. There were no reports of mixed or manic symptoms, psychotic symptoms, or suicidal ideation.

Given the study’s small, open-label design, the findings should be interpreted cautiously, but the investigators say the results are promising.

“The results we saw from this trial are encouraging and further support the clinical study of psychedelics in patients with treatment-resistant bipolar II,” lead investigator Scott T. Aaronson, MD, chief science officer of the Institute for Advanced Diagnostics and Therapeutics at Sheppard Pratt Health System in Baltimore, Maryland, remarked in a press release. “One participant compared the transformation she experienced to taking a deep breath after breathing through a straw for years.”

The findings were published online on December 6, 2023, in JAMA Psychiatry.

Underserved Population

Previous studies show that psilocybin is effective in reducing the symptoms of treatment-resistant depression, major depressive disorder, and anorexia nervosa, most with only mild to moderate adverse effects.

Individuals with bipolar disorder (BPD) have been excluded from psilocybin studies in the last two decades. Investigators attribute this to anecdotal evidence that psychedelics may result in manic episodes in patients with BPD, even though empirical evidence of those effects is limited.

This study included 15 participants (9 female; mean age, 37.8 years) with BDII who had experienced an episode for more than 3 months and failed at least two medications within the current episode.

Participants stopped all psychotropic medications at least 2 weeks prior to the trial and received 25 mg of synthetic COMP360 psilocybin in a controlled setting. Psychotherapy included three sessions before dosing, one during the 8-hour dosing day, and three integration sessions posttreatment.

Depression was measured with the Montgomery Ǻsberg Depression Rating Scale (MADRS) at six points during the 12-week study.

By week 3, all 15 participants had lower MADRS scores, with a mean decrease of 24 points (P < .001). Twelve participants met the response criteria of ≥ 50% reduction in MADRS scores, and 11 met the criteria for remission of a MADRS score of ≤ 10 (both P < .001).

MADRS scores at each posttreatment time point were significantly lower than they were at baseline and the improvement persisted at 12 weeks.

Participants were also monitored for mania and suicidality at various time points during the study, and no significant changes were found from baseline.

“As a first open-label foray into this underserved and treatment-resistant population, care should be taken not to overinterpret the findings,” the authors note, adding that the findings may not apply to patients with BDI or BDII in a mixed or hypomanic phase of their illness.

No Definitive Conclusion

In an accompanying editorial, David B. Yaden, PhD, Johns Hopkins University School of Medicine, Baltimore, Maryland, and colleagues write that the findings are “tantalizingly suggestive,” but ultimately say nothing definitive about the efficacy of psilocybin for BDII.

“The danger is that some individuals will see the large (yet uncontrolled) effect size and believe that a new treatment of bipolar II has been discovered that is substantially better than all other treatments, while neglecting to mention the lack of control condition and substantial psychosocial support included in the study,” Dr. Yaden and colleagues wrote.

They also cautioned that due to the study’s limitations, which include its small sample size and lack of a control group, “it is imperative that the large effect size before to after the study is not overinterpreted.”

However, Dr. Yaden and colleagues also characterized the safety data as “compelling,” noting the safety profile could affect exclusion criteria in future studies involving people with BPD.

“The results of the present study provide preliminary evidence that perhaps those with bipolar II can be safely included in study samples without undue risk of triggering hypomanic episodes,” they wrote. “It also suggests re-evaluation of the need to exclude individuals with mere family history of bipolar II, which several studies do.”

The study was funded by COMPASS Pathways, who provided the study drug. Dr. Aaronson reported grants and nonfinancial support (supply of drug) from COMPASS Pathways during the conduct of the study and personal fees from LivaNova, Neuronetics, Genomind, and Sage Therapeutics outside the submitted work. Other disclosures are noted in the original article.
