Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 65 with a diagnosis of bipolar I disorder currently experiencing a depressive episode.
✕Probably not a fit
Patients with severe cognitive impairment, psychotic disorders, or significant medical conditions may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the efficacy and safety of an NMDA enhancer (NMDAE) in treating cognitive impairment and perceived stress in patients with bipolar I disorder experiencing depressive episodes. Participants, aged 18 to 65, who have been on stable treatment for at least four weeks, will be randomized to receive either NMDAE or a placebo for eight weeks. The study will assess cognitive function and quality of life through various scales and tests at multiple time points. The results will help determine the effectiveness of NMDAE compared to placebo in improving symptoms associated with bipolar depression.
Why it matters
Potential benefit: If successful, this treatment could significantly improve cognitive function and reduce perceived stress in patients with bipolar I disorder.
How similar studies have gone: While NMDA receptor modulation is a novel approach in this context, similar studies have shown promise in treating cognitive dysfunction in other psychiatric disorders.
