Clinical Trial Summary

Evidence suggests that mGLUR5 availability may play a key role in the biology of mood disorders. This study aimed to investigate the changes in metabotropic glutamate receptor 5 (mGLUR5) availability and clinical symptoms in patients with MDD and bipolar disorder(BD) after two months of vortioxetine treatment. The investigators hypothesized that patients with MDD and BP have abnormal mGluR5 availability in certain brain regions, and baseline mGLUR5 availability can predict prognosis the prognosis of MDD and BD. fMRI and NODDI are also used to evaluate the function or neurite condition at baseline and 8 week

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Baseline concentration of mGLUR5 availability	BPND at baseline as measured by PET	Day 0
Primary	Change in concentration of mGLUR5 availability from baseline to 8 weeks	BPND changes from baseline to 8 weeks	Week 8
Primary	Change of Hamilton Depression Rating Scale-17 (HAMD-17) score from baseline to 8 weeks	Change of Hamilton Depression Rating Scale-17 (HAMD-17) score from baseline to 8 weeks, range: 0-51, higher score means more severe symptom of depression	Week 8
