ClinConnect Summary
This clinical trial is studying a new drug called SP-624 to see how it affects brain activity in both healthy adults and adults with major depression. Researchers want to understand if SP-624 can improve memory and learning in those with depression and to gather information about how safe the drug is. Participants will take either SP-624 or a placebo (a pill with no active ingredients) once a day for two weeks. They will visit the clinic for check-ups and tests at the beginning, after one week, and again at the end of the trial.
To be eligible for this study, participants should be generally healthy and have a body mass index (BMI) between 18 and 40. Adults with major depression should meet specific criteria for moderate to severe symptoms. However, pregnant or breastfeeding women, as well as individuals with significant health issues or certain psychiatric conditions, cannot participate. This trial is currently looking for participants aged 18 to 65, and it offers a chance to contribute to understanding how SP-624 may help improve depression and brain function.
