简要总结
The study will assess the safety, tolerability, and pharmacokinetics of basimglurant compared to placebo after multiple ascending oral doses for up to 22 days in healthy subjects and in patients with MDD on stable selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) background therapy.

研究组 & 干预措施
Basimglurant: Healthy Cohort (1)
Healthy participants assigned to basimglurant will receive a 22-day ascending dose regimen. Cohort 1 will receive a prespecified titration scheme; however, adaptive titration schemes may be applied in subsequent cohorts.
干预措施: Basimglurant (Drug)
Basimglurant: Healthy Cohort (2)
Healthy participants assigned to basimglurant will receive a 22-day ascending dose regimen. The dosing scheme for Cohort 2 will be selected in accordance with decision criteria on the basis of the incidence of severe AEs in Cohort 1.
干预措施: Basimglurant (Drug)
Basimglurant: Healthy Cohort (3)
Healthy participants assigned to basimglurant will receive a 22-day ascending dose regimen. The dosing scheme for Cohort 3 will be selected in accordance with decision criteria on the basis of the incidence of severe AEs in preceding Cohorts 1 and 2.
干预措施: Basimglurant (Drug)
Basimglurant: Healthy Cohort (4)
Healthy participants assigned to basimglurant will receive a 22-day ascending dose regimen. The dosing scheme for Cohort 4 will be selected in accordance with decision criteria on the basis of the incidence of severe AEs in preceding Cohorts 1, 2, and 3.
干预措施: Basimglurant (Drug)
Basimglurant: MDD Cohort (5)
Participants with MDD assigned to basimglurant will receive a 22-day ascending dose regimen. The dosing scheme for Cohort 5 may differ from those previously evaluated; however, the titration steps and the highest dose tested will remain equal to or lower than the doses tested in Cohorts 1 to 4.
干预措施: Basimglurant (Drug)
Placebo: Healthy Cohorts (1 to 4)
Healthy participants will receive a 22-day regimen of matching placebo capsules.
干预措施: Placebo (Drug)
Placebo: MDD Cohort (5)
Participants with MDD will receive a 22-day regimen of matching placebo capsules.
干预措施: Placebo (Drug)
