Clinical Trial Summary

The purpose of the Pilot Study Investigating the Efficacy of Minocycline and n-acetylcysteine for Bipolar Depression is to test the effectiveness of minocycline, n-acetylcysteine, and combined minocycline and n-acetylcysteine pharmacotherapy in order to fill the gap in treatments for bipolar depression. The treatment of bipolar depression remains the greatest unmet need in the management of this lifelong and chronic psychiatric disorder.


Clinical Trial Description

The investigators are doing this research study to find out if minocycline alone, N-acetyl cysteine (NAC) alone, or the combination of minocycline and NAC can help people with bipolar depression when added to lithium. The investigators also want to find out if minocycline, NAC, and the combination of minocycline and NAC are safe to take without causing too many side effects. While the U.S. Food and Drug Administration (FDA) has approved minocycline to treat infections and acne and has approved NAC as a mucolytic, the FDA has not approved minocycline, n-acetylcysteine, or the combination of minocycline and n-acetylcysteine to treat bipolar depression. This research study will compare minocycline, n-acetylcysteine, and the combination of n-acetylcysteine and minocycline to placebo. The placebo looks exactly like the other study drugs, but contains neither minocycline nor NAC. During this study participants may get a placebo instead of minocycline, n-acetylcysteine, or the combination of minocycline and n-acetylcysteine. Placebos are used in research studies to see if the results are due to the study drug or due to other reasons. ;
