This study is testing a new drug, ITI-1284, for people with Generalized Anxiety Disorder (GAD). GAD is when you feel anxious or worried all the time. Some people with GAD don't get better with usual treatments. This study will add ITI-1284 to their treatment to see if it helps.
The study has three parts:
- Screening Period: Up to 3 weeks to check if you can join and stop any non-allowed medicines.
- Treatment Period: 6 weeks where you'll get either ITI-1284 (10 mg or 20 mg) or a placebo (a pill with no medicine) without knowing which one.
- Safety Follow-up: 1 week to make sure you're okay after the study.
To join, you must be 18 or older, have tried a GAD treatment that didn't work well, and agree to keep taking it during the study. You can't join if you have certain mental health conditions or a history of not responding to multiple GAD treatments.
- Study lasts about 10 weeks total.
- Regular check-ups and follow-up visit required.
- Potential side effects and no guarantee of improvement.
