U.S. FDA Approves VRAYLAR® (cariprazine) as an Adjunctive Treatment for Major Depressive Disorder

“A Phase 3 Study 3111-301-001 showed a clinically and statistically significant change from baseline to week six in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score for patients treated with cariprazine at 1.5 mg/day + ADT compared with placebo + ADT. A second registration-enabling study, RGH-MD-75, showed a clinically and statistically significant change from baseline to week eight in the MADRS total score for patients treated with cariprazine at 2-4.5 mg/day (mean dose 2.6 mg) + ADT compared with placebo + ADT.

Cariprazine was generally well tolerated in 6- and 8-week studies. Mean weight change was < 2lbs and ? 3% of patients had a weight increase of ? 7%.

The starting dosage of VRAYLAR is 1.5 mg once daily. Depending upon clinical response and tolerability, the dosage can be increased to 3 mg once daily on Day 15. In clinical trials, dosage titration at intervals of less than 14 days resulted in a higher incidence of adverse reactions. The maximum recommended dosage is 3 mg once daily.

Most common adverse reactions observed in the adjunctive MDD studies (? 5% and at least twice the rate of placebo) were:

Akathisia, nausea, and insomnia at the recommended doses in 6-week, fixed-dose trials

Akathisia, restlessness, fatigue, constipation, nausea, increased appetite, dizziness, insomnia, and extrapyramidal symptoms in one 8-week flexible-dose trial at a titration of less than 14 days”

Lithium is a Lifesaver in Bipolar Disorder

Batya Swift Yasgur MA, LSW reported in Medscape Medical News on November 28, 2022 that “Mood stabilizers protect against suicide and all-cause mortality in patients with bipolar disorder (BD), including natural mortality, with lithium emerging as the most protective agent, new research suggests.

Investigators led by Pao-Huan Chen, MD, of the Department of Psychiatry, Taipei Medical University Hospital, Taiwan, evaluated the association between the use of mood stabilizers and the risks for all-cause mortality, suicide, and natural mortality in over 25,000 patients with BD and found that those with BD had higher mortality.

However, they also found that patients with BD had a significantly decreased adjusted 5-year risk of dying from any cause, suicide, and natural causes. Lithium was associated with the largest risk reduction compared with the other mood stabilizers.

Intermittent theta burst magnetic stimulation (iTBS) is FDA approved.

As reported in Psych. News:?The Food and Drug Administration (FDA) has cleared the SAINT Neuromodulation System for the treatment of refractory depression in adults, Magnus Medical Inc. (the manufacturer of the product)?announced?Tuesday. SAINT is a?modified form of transcranial magnetic stimulation?(TMS) that compresses weeks of conventional TMS therapy into just five days”. ?Regular TMS takes 20-30 minutes per daily session while iTBS takes about 5 minutes and thus can be applied many times in a single day. ?”As demonstrated in a clinical trial?published?in?The American Journal of Psychiatry, Montgomery-Åsberg Depression Rating Scale (MADRS) scores dropped by 62% among participants following five days of SAINT stimulation compared with a 14% drop among participants receiving sham stimulation. These improvements were sustained over a four-week follow-up.” ?The method was developed by Nolan Williams and he used MRI to best target the site of stimulation 

Cannabidiol (CBD) does not make cannabis safer

Amir Englund et al reported in Neuropsychopharmacology in A randomised, double-blind, cross-over trial of cannabis with four different CBD:THC ratios that CBD did not protect against the adverse effect of THC. These included impaired delayed verbal recall ( p?=?0.001) and induced positive psychotic symptoms on the PANSS ( p?=?2.41?×?10–5).

Editors Note: Not only does marijuana impair memory, it is a risk factor the onset of bipolar disorder and schizophrenia. When pot is used by a person with a unipolar or bipolar mood disorder, there are increases in depression and anxiety and an overall less favorable course of illness. If a person with a mood disorder uses heavy amounts of marijuana, they could consider buying N-acetylcysteine (NAC) 500mg and increasing the dose to 1,000mg twice a day within a week as this has been shown to decrease drug use compared to placebo in adolescents and young adults using and abusing pot. Most people who sell pot, are not well-informed about its dangers and just want to make money.

Mindfulness-Based Stress Reduction Equivalent to Escitalopram for Treatment of  Anxiety Disorders

December 1, 2022 · Posted in Current Treatments, Potential Treatments · Comment 

Hoge et al reported in JAMA Psychiatry (2022) that in a randomized clinical trial of 276 adults with anxiety disorders, 8-week treatment with mindfulness-based stress reduction (MBSR) was noninferior to escitalopram.  The “MBSR is a manualized 8-week protocol with weekly 2.5-hour long classes, a day-long retreat weekend class during the fifth or sixth week, and 45-minute daily home practice exercises…. Qualified instructors taught the theory and practice of several forms of mindfulness meditation, such as breath awareness (focusing attention on the breath and other physical sensations), a body scan (directing attention to one body part at a time and observing how that body part feels), and mindful movement (stretching and movements designed to bring awareness to the body and increase interoceptive awareness)….Escitalopram was initiated at 10 mg daily orally and increased to 20 mg daily at week 2 if well tolerated or delayed if not.”  The investigators concluded that “mindfulness-based stress reduction was a well-tolerated treatment option with comparable effectiveness to a first-line medication for patients with anxiety disorders.”

Cariprazine Effective in AD-resistant MDD

Maletic, V, et al. reported on Efficacy of Adjunctive Cariprazine Across Individual Depressive Symptoms in Major Depressive Disorder:  A Post-Hoc Analysis. Poster presented at Psych Congress 2022; September 17-20, 2022.

“With 751 patients (502 on CARIPRAZINE (CAR) and 249 on PBO), the LSMD (95% CI) score change from baseline to week 6 was significant in favor of CAR. Items of the MADRS scale were assessed individually over the course of the study, including apparent sadness, reported sadness, reduced appetite, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts, showing improvement compared to PBO. “

Lithium Corrects Circadian Rhythm Abnormalities in Bipolar Depression

April 2, 2021 · Posted in Current Treatments · Comment

At a recent scientific meeting, researcher Monica Federoff described new findings about lithium’s effects in people with bipolar I disorder, especially regarding circadian rhythms. The 12-week study included 386 participants with bipolar I. Some participants responded well to lithium, but even those whose bipolar disorder did not remit saw improvements in total symptoms, depressive symptoms, and manic symptoms.

Only those who were classified as good responders to lithium treatment showed improvement in circadian symptoms. Their depression improved in the direction of more “morningness,” and the authors suggested that “stabilization of circadian symptoms of depression may be an essential feature of lithium’s therapeutic effects in [bipolar] I patients.”

No Association of Benzodiazepines, Z Drugs and Other Anxiolytics with Dementia

October 13, 2020 · Posted in Current Treatments, Risk Factors · Comment 

Benzodiazepines, so-called Z-drugs (such as zolpidem, zopiclone, and zaleplon), and other anxiolytics are commonly prescribed drugs that have some cognitive side effects. For this reason, there has been concern that the drugs may increase risk of dementia, and small studies had suggested that this might be the case. However, a new large study found no subsequent dementia risk after taking these drugs.

In a 2020 article in the American Journal of Psychiatry, researchers Merete Osler and Martin Balslev Jørgensen described a cohort and nested case-control study of 235,465 adult patients in Denmark in which they found no association of benzodiazepines, Z-drugs, or other anxiolytics with a subsequent diagnosis of dementia. Participants were patients over the age of 20 who were hospitalized for an affective disorder. Of these, 75.9% had been prescribed one of the drugs in question, and 4.2% went on to be diagnosed with dementia.

While participants in this study who had the lowest use of benzodiazepines or Z drugs showed a minimal increased risk of dementia compared to those who took none of these drugs, those who had the highest use of benzodiazepines and Z drugs actually had the lowest incidence of dementia in the study.

The previous studies may have been “confounded by indication” meaning they did not take the underlying psychiatric condition for which the drugs were prescribed into account.

Dr. Post’s Recommendations For Treating Youth with Bipolar Symptoms

April 14, 2020 · Posted in Current Treatments, Potential Treatments · Comment 

Teens

Our Editor-in-Chief, Dr. Robert M. Post, shares his personal recommendations for the treatment of children and adolescents with symptoms of bipolar disorder. Remember: Patients and family members must consult a physician about all information conveyed in the BNN. With the exception of lithium, none of the medications or supplements discussed above have been approved by the US Food and Drug Administration for use in children under 10. The findings reported here are in many cases preliminary and cannot be taken as recommendations based on the short summaries provided here. All treatment decisions must be made in conjunction with a patient’s treating physician, who is solely responsible for initiating any treatment discussed in the BNN or elsewhere.

In symptomatic and functionally impaired children, medication is almost always necessary. Many treating psychiatrists would start with an atypical antipsychotic, since there is clear evidence of the efficacy of such treatments. The side effects profile should be considered, as there is a considerable difference in the degree of weight gain associated with different atypical antipsychotics. The largest weight gains occur with olanzapine and clozapine, intermediate gains occur with aripiprazole and quetiapine, and the least gains occur with ziprasidone and lurasidone (and the latter has the advantage of being approved by the US Food and Drug Administration for the treatment of bipolar depression in children who are 10–17 years old). The addition of the diabetes drug metformin to decrease weight gain in people taking atypical antipsychotics is increasingly common.

The addition of an anticonvulsant medication (such as lamotrigine, carbamazepine/oxcarbazepine, or valproate) or the mood stabilizer lithium may be needed, as multiple studies indicate that combination treatment is typically needed in children (as in adults) to achieve a more complete response or remission.

Interestingly, oxcarbazepine was effective in younger but not older children with mania in a previous placebo-controlled study by Karen D. Wagner and colleagues published in the American Journal of Psychiatry in 2006.

Conversely, in a 2015 article in the journal JAACAP, researcher Robert Findling reported that in a placebo-controlled study of lamotrigine, 13–17-year-olds responded better than 10–12-year-olds.
Lithium treatment deserves consideration in children with classical presentations of bipolar disorder and those who have family members who have responded well to lithium treatment.

Lithium has the benefit of improving the white matter abnormalities seen in the brains of patients with early-onset bipolar disorder. Hafeman and colleagues reported in a 2019 article that children with bipolar disorder who were treated with lithium had better long-term results upon follow up than those treated with atypical antipsychotics or anticonvulsants.

There is much less scientific consensus about other adjunctive treatments for young people with additional bipolar symptoms and comorbidities, but this editor often uses several. Vitamin D3 is often low in children with psychiatric illness, and may improve mood and cognition.

The antioxidant N-acetylcysteine (NAC) helps depression, anxiety, and irritability, and is effective at treating habit-related behaviors such as trichotillomania (compulsive hair-pulling), obsessive-compulsive disorder (OCD), and drug use, including specifically reducing marijuana use in adolescents. A typical dose is 500–600 mg capsules, one capsule twice a day for one week, then two capsules in the morning and two in the evening thereafter.

Folate or folic acid may enhance antidepressant effects and those of lithium. In patients who have a particular low-functioning variant of a gene known as MTHFR, L-methylfolate is required instead of folate.

The widely-used supplement acetyl-L-carnitine (ALC) is poorly studied in children, but deserves consideration as a supplemental treatment for patients with histories of childhood adversity. In adults with depression, blood levels of ALC may be low, particularly in those with an early onset of bipolar symptoms and a history of childhood adversity (see a 2018 article by Carla Nasca in the journal PNAS). There is a modicum of evidence that ALC produces antidepressant effects in adults. ALC may also sensitize insulin receptors and normalize blood pressure.

There is increasing evidence of the role of inflammation in depression, mania, post-traumatic stress disorder (PTSD), and schizophrenia. Checking for abnormalities in inflammatory markers in the blood (especially Il-6 and CRP) may point the way to appropriate therapy with anti-inflammatory drugs such as minocycline (100 mg twice a day) or celecoxib (200 mg twice a day) in patients who do not respond fully to first-line medications.
