MDD患者におけるGM-2505の安全性と忍容性を評価する第2a相試験
大うつ病性障害患者を対象に、GM-2505を2週間間隔で2回反復投与した場合の安全性と忍容性を評価する第2a相試験。
This is a three-part Phase 2a study. The aim of Part A is to assess the safety and tolerability and preliminary antidepressant efficacy in patients with MDD who are not currently on an antidepressant therapy. The aim of Part B is to assess the antidepressant efficacy, safety and tolerability in patients with MDD who are partial responders while on a current and adequate single SSRI or SNRI treatment. Part C aims to replicate the monotherapy findings of Part A, but with a lower control group dose.

-
Current moderate to severe MDD diagnosis confirmed with a MADRS-SIGMA
-
Concomitant depression therapy:
- (Part A) Patients need to be stable and must not have taken any SSRI or SNRI for at least 6 weeks prior to Screening and must be willing to avoid starting a new pharmacological treatment for MDD until the end of the study procedures and assessments. Discontinuing current treatment is not allowed if done for the purposes of achieving eligibility for this study.
