The Effect of CORT118335 on Olanzapine-Induced Weight Gain
Phase 1
Completed
- Conditions
- Antipsychotic-induced Weight Gain
- Interventions
- Registration Number
- NCT03877562
- Lead Sponsor
- Corcept Therapeutics
- Brief Summary
This study will investigate if there is any difference in the amount of weight gained by participants taking olanzapine with CORT118335 compared with olanzapine with placebo (a dummy test medicine which looks like CORT118335 but contains no active medicine). Safety and tolerability of CORT118335 when taken with olanzapine will also be evaluated.
