The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

* Adult with treatment-resistant depression (TRD: not responded adequately to at least two different antidepressants of adequate dose and duration) who has a current depressive episode (DSM 5)

* Assessed and attested by clinic psychiatrist as appropriate to receive either racemic ketamine or Spravato® ketamine treatment for TRD

* MADRS score of ≥20 at study baseline, assessed by certified study rater

* Aged ≥18 years

* Written informed consent for research study obtained

Exclusion Criteria:

* Not able to give informed consent

* Any physical or mental condition which, in the opinion of the investigator, could interfere with study participation including outcome assessments

* Any treatment with ketamine or Spravato® within 4 weeks prior to written informed consent for the research study

* Patients who require an interpreter/translator for the clinic consent process, due to the infeasibility of obtaining an interpreter for research assessments, including self-rated scales

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
