• Male or female aged 18 to 45 years, inclusive at screening.

• Male or female patients. Women of childbearing potential (WOCBP) and men able to father a child must be ready and able to use highly effective methods of birth control.

• Patients must be, in the opinion of the Investigator, capable of and eligible for completing the fMRI and tasks.

• Patients must be right-handed.

• Patients must have acceptable weight as defined by BMI (weight [kg]/height [m]²) range of 18 to 30 kg/m², inclusive at Visit 1.

• Patients must be a non-smoker or light smoker (≤ 5 cigarettes per day).

• Patients must have signed the informed consent form prior to the first study-related procedure indicating they understand the purpose of and procedures required for the study and are willing to participate in the study.

• Further inclusion criteria apply

Exclusion Criteria:

• Meeting any diagnostic criteria for a major psychiatric disorder (other than MDD), as determined by DSM-V at screening.

• Has received a prescribed medication (including antidepressants) within 28 days prior to Visit 1 (apart from the contraceptive pill) or having received over the counter medication (including pain killers) within 10 days prior to screening. Participants who have taken prescription medication may still be entered into the study, if, in the opinion of the Investigator, the medication received will not interfere with the study procedures or compromise safety.

• Patients where it is foreseen (per investigator judgement) that a delay of initiation of standard of care therapy for the depressive disorder to 14 days after day 1 of Visit 2 is medically not justifiable.

• A history of alcohol or substance dependence or abuse within the last 12 months from Visit 1.

• Has a current or recent history of clinically significant suicidal ideation within the past 6 months, corresponding to a score of 4 or 5 for ideation on the C-SSRS, or a history of suicidal behavior within the past year, as validated by the C-SSRS at screening or treatment visit.

• Has a history of, or presents (in the opinion of the Investigator) with, significant neurological or psychiatric conditions (such as stroke, traumatic brain injury, seizures, space occupying lesions, multiple sclerosis, Parkinson's disease, vascular dementia, transient ischemic attack, schizophrenia, blackouts requiring hospitalisation).

• A planned medical treatment within the study period that might interfere with the study procedures.

• Further exclusion criteria apply
