- Positive result at Visit 1 from the urine drug screen (UDS) test for any prohibited medication. Exception: participants with a positive UDS at Visit 1 for opiates, cannabinoids, or episodic use of benzodiazepines may be allowed in the study provided:
- The drug was used for a legitimate medical purpose;
- The drug can be discontinued prior to participation in the study (except for episodic use of benzodiazepines which may be continued); and
- A repeat UDS is negative for these substances prior to enrollment (except for episodic use of benzodiazepines which may be continued)
- Suicide risk, as determined by meeting any of the following criteria:
- A suicide attempt within the past year
- Significant risk, as judged by the investigator, based on the psychiatric interview or information collected in the C-SSRS at Visit 1 (Screening) or Visit 2 (Baseline)
- MADRS Item 10 score ≥ 5 at Visit 1 (Screening) or Visit 2 (Baseline) on the MADRS
- At imminent risk of injuring self or others or causing significant damage to property, as judged by the investigator.
- Requiring concomitant treatment with any of the prohibited medications, supplements, or herbal products listed in Appendix 6 of protocol, including any psychotropic drug or any drug with psychotropic activity, except as described in Section 7.7.2. of protocol.
- Prior participation in any investigational study of AGN-241751.
- Initiation or termination of psychotherapy for depression within the 3 months preceding Visit 1, or plans to initiate, terminate, or change such therapy during the course of the study.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
Time Frame: Baseline to Day 1
|
The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week.
Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity).
The total score ranges from 0 to 60 with a higher score indicating more depression.
A negative change score indicates improvement.
