Key Exclusion Criteria: * Have failed 2 or more courses of antidepressant treatment at sufficient doses for at least 6 to 8 weeks for the current MDD episode. * Currently or in the past year have been diagnosed with a personality disorder per the DSM-5-TR or in the past 3 years have been diagnosed with any of the following DSM-5-TR disorders: anorexia nervosa, bulimia nervosa, or binge eating disorder. Participants with comorbid generalized anxiety disorder, social anxiety disorder, simple phobias, or panic disorder for whom MDD is considered the primary diagnosis are not excluded. * Have a lifetime diagnosis of bipolar 1 or 2, schizophrenia, schizoaffective, schizophreniform, obsessive compulsive disorder, or post-traumatic stress disorder (PTSD). * Have moderate to severe substance or alcohol use disorder, per DSM-5-TR criteria, within the 12 months prior to screening (excluding nicotine). * Are actively suicidal (eg, any suicide attempts within the past 12 months) or are at serious suicidal risk as indicated by any current suicidal intent, including a plan, as assessed by the Columbia Suicide Severity Rating Scale (C-SSRS) (score of "YES" on suicidal ideations Item 4 or 5 within 3 months prior to Visit 1 \[Screening\]) and/or based on clinical evaluation by the Investigator; or are homicidal, in the opinion of the Investigator. Participants who are currently hospitalized for MDD symptoms or suicidality are not allowed into the study. If there is a recent history (within 3 months of screening) of hospitalization due to MDD symptoms, the participant should be discussed with the Medical Monitor for eligibility.
