- Brief Summary
NMDA antagonist drugs have shown to reduce symptoms of depression and suicidal ideation. NeuroRx has developed NRX-101 (fixed dose combination of D-cycloserine and lurasidone) for oral use in the treatment of bipolar depression with suicidal ideation. This study will test the hypothesis that NRX-101 is superior to lurasidone alone (standard of care) in maintaining remission from symptoms of depression (primary endpoint) and suicidal ideation or behavior (declared secondary endpoint) over a six week period of twice-daily oral dosing.
- Detailed Description
Background and Rationale: NMDA antagonist drugs have shown to reduce symptoms of depression and suicidal ideation. NRX-101 is composed of D-cycloserine (DCS) an NMDA antagonist and lurasidone (5HT2a atypical antipsychotic and antidepressant). In a phase 2 clinical study of bipolar depression and acute suicidal ideation and behavior, (in patients requiring hospitalization) patients received an initial infusion of ketamine and then NRX-101 for 6 weeks. In that phase 2 study, NRX-101 showed the ability to maintain remission from depression and suicidality over 6 weeks when taken twice daily. In this current out patient study, patients with bipolar depression and subacute suicidality (not requiring hospitalization), ketamine will not be used.
Primary Objective:
* To test the hypothesis that treatment with NRX-101 is superior to standard of care (lurasidone) in improving symptoms of depression as measured by the total Montgomery Åsberg Depression Rating Scale (MADRS-10) score in patients with bipolar depression and subacute suicidal ideation and behavior (SSIB) which does not require hospitalization.
Secondary Objectives:
• To test the hypothesis that treatment with NRX-101 is superior to standard of care (lurasidone) in reducing suicidality in depressed bipolar patients with SSIB, as measured by the Columbia Suicide Severity Rating Scale (C-SSRS)
Methodology: : A multi-center, randomized, double-blind, trial in which patients with bipolar depression (MADRS ≥30) and subacute levels of suicidal ideation (C-SSRS 3 or 4, not requiring hospitalization) are randomized to receive twice daily oral NRX-101 or lurasidone (standard of care).

- Primary Outcome Measures
Name Time Method Change from Baseline in MADRS-10 over 42 Days Six weeks Mean change from baseline to endpoint (Day 42/exit) in total MADRS score, a 10-item clinician-rated scale, with each item rated on a 0-6 severity scale (0 Minimum, 60 maximum), where higher scores indicate a worse outcome
- Secondary Outcome Measures
Name Time Method Mean Change from baseline in CGI-SS Six Weeks Mean change from baseline to exit (Day 42/exit) in CGI-SS score
Time to Treatment Failure 6 weeks Time to relapse, where relapse is defined as experiencing a return of suicidality in the Columbia Suicide Severity Rating Scale (C-SSRS) of \>=4)), or a return to baseline levels of depression following an improvement of 25% or greater on the MADRS score, or the need to implement a new treatment plan. The C-SSRS is a low-burden measure of the spectrum of suicidal ideation and behavior that was developed in the National Institute of Mental Health Treatment of Adolescent Suicide Attempters Study to assess severity and track suicidal events through any treatment. A lower score on the C-SSRS indicates a better outcome (min=0, max=5)
