Now enrolling ALTO-100-211 Study

8th May 2026

What is Bipolar Depression?

Bipolar depression is diagnosed based on a history of mania or hypomania and the presence of a current major depressive episode. Symptoms can impair your functioning at work or school, your social and personal relationships, and other important aspects of your life.

ALTO-100-211 Study

The purpose of this research study is to compare the effects of ALTO-100, the study’s investigational drug, versus a placebo (an inactive substance) in treating symptoms of depression in participants who have bipolar disorder (BD) with depression (BD-D) and who are also taking mood stabilizers and/or an atypical antipsychotic.

The study will last approximately 3 to 4 months, consisting of a screening period followed by a treatment period where you may receive ALTO-100 or the placebo. Eligible participants will receive study-related care and evaluations at no cost. Compensation for your time and travel may be available.

Importantly, as a study participant you will remain under the care of your current doctor while also working with a team of research doctors and study staff who will monitor your overall health while participating in the trial.

Am I Eligible?
