Multiple Medications for Bipolar Depression
(SMART-BD Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests four treatments for bipolar depression to determine which is most effective during a depressive episode. The treatments include three FDA-approved medications—Cariprazine, Quetiapine, and Lurasidone (all antipsychotics)—and a combination of Aripiprazole and Escitalopram (an antipsychotic and an antidepressant). It is open to adults with bipolar disorder type 1 who have experienced a depressive episode for at least six weeks and can participate as outpatients. Participants should not currently have manic episodes or substance use issues that would interfere with the study. As a Phase 4 trial, this research aims to understand how these FDA-approved treatments benefit more patients.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop your current medications. However, if you are currently taking any of the study medications, you may not be eligible to participate.
What is the safety track record for these treatments?
Research has shown that the treatments in this trial have been generally safe and well-tolerated in past studies. Here is a closer look at each one:
1. **Cariprazine**: Previous studies found cariprazine to be generally safe. Common side effects include nausea, restlessness, and movement-related issues such as a feeling of inner restlessness (akathisia) and movement disorders (extrapyramidal symptoms). These effects occurred in more than 5% of patients but are usually mild.
2. **Aripiprazole/Escitalopram combination**: Studies on aripiprazole and escitalopram separately have shown they are well-tolerated. Aripiprazole, when used as an additional treatment, has a good long-term safety record. Both medicines are also FDA-approved for other conditions, indicating a reasonable safety history.
3. **Lurasidone**: Research has found lurasidone to be generally safe for long-term use, even up to two years. It has a low rate of side effects and is effective for treating bipolar depression.
4. **Quetiapine**: This medication is used for bipolar depression and is typically safe. However, it can cause side effects like dizziness, sleepiness, and dry mouth, but these are usually manageable.
In summary, all these treatments have been tested before and are generally considered safe, with some mild side effects that are common but manageable.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about these treatments for bipolar depression because they offer unique approaches compared to standard options like lithium, valproate, or olanzapine. The Aripiprazole/Escitalopram combination may provide the dual benefit of mood stabilization and enhanced antidepressant effects, potentially improving overall symptom management. Cariprazine stands out for its selective action on dopamine receptors, which might offer better control of depressive symptoms with fewer side effects. Lurasidone is appreciated for its favorable side effect profile, particularly regarding weight gain and metabolic issues, which are common concerns with other treatments. Quetiapine is noted for its rapid onset of action, which could bring quicker relief to patients in acute depressive episodes. Each of these treatments brings something new to the table, offering hope for more personalized and effective management of bipolar depression.
What evidence suggests that this trial's treatments could be effective for bipolar depression?
In this trial, participants will join one of several treatment arms to evaluate different medications for bipolar depression. Cariprazine, one of the treatments under study, has significantly reduced depressive symptoms and improved overall functioning in people with bipolar I disorder, according to previous research. Lurasidone, another treatment option in this trial, effectively reduces depression and anxiety, with improvements often seen as early as two weeks into treatment. Quetiapine, also being tested, has improved depressive symptoms and overall quality of life for those with bipolar disorder. Additionally, the combination of aripiprazole and escitalopram, which participants may receive, may enhance quality of life and thinking skills, although aripiprazole alone works better for manic episodes rather than depressive ones. Research strongly supports these treatments for improving depressive episodes in bipolar disorder.56789
Are You a Good Fit for This Trial?
Adults over 18 with bipolar disorder type 1 who are currently in a depressive episode can join this trial. It's not specified, but typically participants need to meet certain health criteria and may be excluded for various reasons such as other medical conditions or treatments that could interfere with the study.Inclusion Criteria
