Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary objectives * To determine if 3-month PMTERGO decreases depressive symptoms in subjects with MDD * To determine if 3-month PMTERGO alters in vivo striatal DRD2/3 BP compared to pre-intervention levels in subjects with MDD | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary objectives: * To determine if medium-intensity ergocycle exercise acutely lowers in vivo striatal DRD2/3 BP in subjects with MDD compared to pre-ergocycle exercise levels. * To determine whether 3-month PMTERGO modulates reward processing between key reward-related brain regions. * To determine correlations between acute medium-intensity ergocycle exercise-induced changes in neuroendocrine hormones and metabolites and acute changes in in vivo striatal DRD2/3 BP. * To assess 3-month PMTERGO-induced changes in neuropsychological function, lifestyle and dietary patterns. * To determine correlations between 3-month PMTERGO-induced changes in fasting neuroendocrine hormones and in vivo striatal DRD2/3 BP. | — |
