What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused

Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This study looks at the long-term safety and effectiveness of an experimental drug called NMRA-335140 for people with major depressive disorder. About 1,000 adults who completed earlier studies of this drug will take it for 52 weeks. Researchers will track side effects and changes in depression symptoms to see if the drug remains safe and helpful over time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: Rollover participants are eligible for the study if the following inclusion criteria are met: * Completed a previous NMRA-335140 Phase 3 MDD study (example: NMRA-335140-301, NMRA-335140-302, or NMRA-335140-303) according to the completion definition in the parent study protocol. * Signed an informed consent form (ICF) for this study. * Willing to comply with the contraception requirements described in the inclusion criteria of the parent study protocol. * Willing to comply with the concomitant medication/therapy restrictions described in the exclusion criteria of the parent study protocol. Key Exclusion Criteria: Rollover participants are excluded from the study if any of the following exclusion criteria are met: * Diagnosed with another Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) disorder that would have been exclusionary in the parent study (eg, personality disorder, bipolar 1 or 2, schizophrenia, any other psychotic disorder, or moderate or severe substance or alcohol use disorder \[excluding nicotine\]). * Considered to be at significant risk of suicide in the judgment of the Investigator. This includes participants who are actively suicidal (eg, any suicide attempts during the parent study) or are at serious suicidal risk as indicated by any current suicidal intent, including a plan, as assessed by the C-SSRS ("Since Last Visit" version, score of "YES" on suicidal ideation Item 4 or 5) and/or based on clinical evaluation by the Investigator; or are homicidal, in the opinion of the Investigator. * Non-adherent with study medication (took ≤70% of study drug over any 2-week visit interval) or procedures during the parent study. * Experienced treatment emergent adverse events (TEAEs) considered related to the study medication from the parent study and judged by the Investigator to be clinically significant to render the participant ineligible for enrollment. * Have an abnormality on ocular examination that would prohibit continued study participation as determined by the Investigator. * Use of disallowed concomitant medication or therapy that would have been exclusionary in the parent study, may compromise the safety of the participant, and/or confound the interpretation of protocol assessments. * Considered by the Investigator to be inappropriate for any other reason.
