What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to assess antidepressant efficacy differences between ALTO-100 and placebo during the Double-Blind period in patients with bipolar disorder I or II with current major depressive episode, when used adjunctively to a mood stabilizer, related to patient characteristics. Additionally, safety, tolerability, and efficacy will be assessed in a subsequent open label treatment period.

Will I have to stop taking my current medications?

The trial requires participants to continue taking a mood stabilizer like lithium, lamotrigine, or valproic acid, without changing the dose for at least 6 weeks before starting. If you're on other medications, the protocol doesn't specify, so it's best to discuss with the trial team.
