E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of rapastinel (450 mg IV) versus placebo and vortioxetine (10-20 mg oral) versus placebo in the treatment of MDD, as measured by the change from baseline Montgomery-Åsberg Depression Rating Scale (MADRS) total score at end of treatment (end of week 6) |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of rapastinel (450 mg IV) versus placebo and vortioxetine (10-20 mg oral) versus placebo in the treatment of
MDD, as measured by the change from baseline MADRS total score at 1 day post-first dose of treatment |

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacogenetic
Blood samples may be collected at any time between Visits 2
and 9, inclusive, in support of pharmacogenetic biobanking
and analysis. Participation is optional.
Pharmacokinetic
Sparse pharmacokinetic (PK) samples will be taken from patients consenting to optional PK sampling to determine plasma concentrations of rapastinel using a validated bioanalytical method. |

E.3 | Principal inclusion criteria |
●Male and female outpatients who are 18 to 75 years of age
●Meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for MDD (based on confirmation from the Structured Clinical Interview for Diagnostic Statistic Manual of Mental
Health Disorders, Fifth Edition [SCID]), with a current major depressive episode of at least 8 weeks and not exceeding 18 months in duration at Visit 1
●Have a minimum score of 26 on the rater-administered Montgomery-Åsberg Depression Rating Scale (MADRS) and a minimum score of 24 on the computer administered MADRS at screening (Visit 1) and baseline (Visit 2)
●Have a Clinical Global Impressions - Severity (CGI-S) score of ≥ 4 at screening and baseline
●Inadequate response (< 50% reduction in depressive symptoms) to 1 to 3 antidepressant therapies [ADTs] given at adequate doses (as defined by the ADT package insert) and duration of ≥ 4 weeks during the present episode as documented using the Antidepressant
Treatment Response Questionnaire [ATRQ] |

E.4 | Principal exclusion criteria |
●DSM-5–based diagnosis of any disorder other than MDD that was the primary focus of treatment within 6 months before Visit 1. Comorbid generalized anxiety disorder, social anxiety disorder, or specific phobias are acceptable provided they play a secondary role in the balance of symptoms and are not the primary driver of treatment
decisions.
● Lifetime history of meeting DSM-5 criteria for:
a. Schizophrenia spectrum or other psychotic disorder
b. Bipolar or related disorder
c. Major neurocognitive disorder
d. Neurodevelopmental disorder of greater than mild severity or of a severity that impacts the patient’s ability to consent, follow study directions, or otherwise safely participate in the study
e. Dissociative disorder
f. Posttraumatic stress disorder
g. MDD with psychotic features
●History of meeting DSM-5 criteria for alcohol or substance use disorder (other than nicotine or caffeine) within the 6 months before Visit 1
● DSM-5–based diagnosis of any personality disorder of sufficient severity to interfere with participation in this study in the opinion of the investigator
● History (based on patient report, medical records, and investigator judgement) of:
a. Inadequate response to electroconvulsive therapy (ECT), a monoamine oxidase inhibitor or ketamine
b. Treatment with clozapine or any depot antipsychotic (exception: episodic use of clozapine at doses ≤ 150 mg/day for the treatment of insomnia)
c. ECT, vagus nerve stimulation, transcranial magnetic stimulation, or any experimental central nervous system treatment during the current episode or in the 6 months before Visit 1 (whichever is longer)
d. Tardive dyskinesia, serotonin syndrome, or neuroleptic malignant syndrome
e. Intolerance or hypersensitivity to rapastinel or vortioxetine
●Having received:
a. Anticonvulsant/mood stabilizer, within 1 year prior to Visit 1
b. Antipsychotic in the current episode, with the exception of quetiapine ≤ 50 mg/day or clozapine ≤ 150 mg/day given for insomnia provided it can be safely discontinued prior to Visit 2
c. Treatment with lithium as an ADT augmentation agent in the current episode
● Positive result at Visit 1 from the urine drug screen (UDS) test for any prohibited medication. Exception: patients with a positive UDS at Visit 1 for opiates, cannabinoids or episodic use of benzodiazepines may be allowed in the study provided:
a. The drug was used for a legitimate medical purpose (any recreational use is exclusionary);
b. The drug can be discontinued prior to participation in the study (except for episodic use of benzodiazepines which may be continued); and
c. 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. A suicide attempt within the past year
b. Significant risk, as judged by the investigator, based on the psychiatric interview or information collected in the C-SSRS at Visit 1 or Visit 2
c. MADRS Item 10 score ≥ 5 at Visit 1 or Visit 2 on either the rater administered MADRS or computer-administered 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, including any psychotropic drug or any drug with psychotropic activity.
● Prior participation in any investigational study of rapastinel/GLYX-13
●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. (Support meetings or counseling [eg, marital counseling] are allowed provided they are no more frequent than weekly and do not have treatment of depression as their objective)
● Ongoing treatment with phototherapy, or termination of phototherapy within 1 month of Visit 1
