Trial Summary

What is the purpose of this trial?

This trial is testing whether lurasidone can help improve thinking and memory in people with bipolar disorder who are currently stable but have cognitive problems. The medication works by balancing brain chemicals. Lurasidone has shown potential in improving thinking and memory in both schizophrenia and bipolar disorder.

Do I have to stop taking my current medications for the trial?

The trial requires that you stay on your current mood stabilizer or atypical antipsychotic at a stable dose for two weeks before randomization. However, you cannot take certain medications like procognitive drugs, clozapine, tricyclic antidepressants, or strong CYP3A4 inhibitors and inducers.

What data supports the idea that the drug Lurasidone for Cognitive Improvement in Bipolar Disorder is an effective treatment?

The available research shows that Lurasidone is effective in treating bipolar disorder, particularly in reducing depressive symptoms. In studies, Lurasidone was compared to a placebo and showed a significant reduction in depression scores, with more than 50% improvement in some cases. It was also noted for having fewer side effects like weight gain compared to other similar drugs. However, specific data on cognitive improvement in bipolar disorder is limited, and more research is needed to confirm its effectiveness in this area. ^{1 2 3 4 5}

What safety data is available for lurasidone in treating bipolar disorder?

Lurasidone has been studied in various clinical trials for its safety and efficacy in treating bipolar disorder. It is approved for use in adults with bipolar I depression, either as monotherapy or as an adjunct to lithium or valproate. Clinical trials have shown that lurasidone is associated with minimal weight gain and no significant changes in glucose, lipids, or the QT interval. Common adverse events include akathisia, extrapyramidal symptoms, and somnolence. It has a favorable safety profile compared to some other antipsychotics, particularly regarding weight gain and metabolic disturbances. Long-term safety data in older adults and children also suggest a favorable tolerability profile. ^{2 3 6 7 8}

Is the drug Lurasidone a promising treatment for improving cognition in people with bipolar disorder?

Yes, Lurasidone is a promising drug for improving cognition in people with bipolar disorder. It has shown effectiveness in reducing depressive symptoms and has a favorable safety profile, with minimal weight gain and no significant changes in glucose or lipids. It can be used alone or with other medications like lithium or valproate. ^{1 2 3 6 9}

Findings from Research

In a pilot study involving 34 euthymic bipolar I disorder patients, lurasidone adjunctive therapy significantly improved global cognition scores compared to treatment as usual (TAU), with a moderate to large effect size of 0.82.

While lurasidone showed promising cognitive benefits, it also had a higher incidence of adverse events (60% in the lurasidone group vs. 13% in TAU), indicating the need for careful monitoring in clinical use.

Lurasidone significantly reduced depressive symptoms in adults with bipolar I disorder, achieving over a 50% reduction in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score compared to placebo in two 6-week trials, with a low number needed to treat of ≤7 for an additional response.

The medication has a favorable safety profile, with lower risks of weight gain and metabolic disturbances compared to other antipsychotics, although common side effects included akathisia and extrapyramidal symptoms.

Lurasidone: a review of its use in adult patients with bipolar I depression. Sanford, M., Dhillon, S.[2018]

Lurasidone is an atypical antipsychotic approved for treating bipolar depression, showing greater efficacy than placebo when used alone or with lithium or valproate, based on clinical trials.

It has a favorable safety profile, with minimal weight gain and no significant changes in glucose, lipids, or heart rhythm, making it a promising option for managing depressive episodes in bipolar disorder.

In a six-week randomized, double-blind trial involving 76 patients with Bipolar I or II, Lurasidone demonstrated a significantly better response rate (66%) in reducing symptoms compared to placebo (42%).

The study indicated that Lurasidone is effective in improving overall health and managing bipolar symptoms, with patients tolerating the drug well and showing no significant adverse effects.

In a study of 61 bipolar disorder patients, lurasidone was found to significantly reduce syndromal depression rates by nearly half and increase euthymia rates, suggesting its effectiveness as an adjunctive treatment.

However, 54.1% of patients discontinued lurasidone primarily due to adverse events like akathisia and weight gain, indicating challenges with tolerability in this population already on multiple medications.

Lurasidone monotherapy significantly improved depressive symptoms in patients with non-rapid cycling bipolar depression compared to placebo, with effect sizes of 0.47 and 0.41 for the 20-60 mg/day and 80-120 mg/day doses, respectively.

In patients with rapid cycling bipolar depression, while lurasidone showed some reduction in depressive symptoms, the improvement was not statistically significant, likely due to a small sample size and high placebo response.

Lurasidone is a newly approved antipsychotic for children, showing efficacy in treating schizophrenia and bipolar disorder, with a favorable safety and tolerability profile for long-term use.

The drug has also been explored for off-label uses in childhood conditions such as autism spectrum disorders and Tourette's syndrome, demonstrating effectiveness across various psychopathological symptoms.

A 6-month treatment with lurasidone in older adults with bipolar I depression showed significant improvement in depressive symptoms, with mean reductions in the Montgomery-Åsberg Depression Rating Scale (MADRS) scores of -6.2 for monotherapy and -6.7 for adjunctive therapy.

Lurasidone treatment was well tolerated, with minimal impact on weight and metabolic parameters, and low rates of switching to hypomania or mania, indicating its safety for older patients.

In a cost-effectiveness analysis over a 3-month period involving patients with bipolar depression, lurasidone was found to achieve a higher remission rate (52.0%) compared to quetiapine XR (43.2%), indicating it may be more effective in treating this condition.

Despite slightly higher total costs for lurasidone ($4982 vs $4676), it demonstrated a favorable incremental cost-effectiveness ratio of $3474 per remission, with an 86% probability of being cost-effective compared to quetiapine XR at a willingness-to-pay threshold of $10,000 per remission.
