Descriptive Information
Brief Title  ICMJE NRX101 Glx Biomarker Validation Study
Official Title  ICMJE Validation of the Glx Biomarker for Treatment of Moderate Bipolar Depression With NRX-101
Brief Summary Subnormal level of Glutamate+Glutamine (Glx) in the Anterior Cingulate Cortex (ACC) of the brain has been associated with depression and PTSD. Similarly, interventions that increase the level of Glx in the brain, specifically electroconvulsive therapy (ECT) and intravenous ketamine infusion have been associated with a rapid decrease in depression and suicidal ideation. This effect has been demonstrated in a dose-dependent manner in randomized clinical assessments. D-cycloserine, a glycine site modulator of NMDA receptor function has been demonstrated to increase Glx in the ACC of normal volunteers. The purpose of this study is to determine whether NRX-101, an experimental drug containing a fixed dose combination of D-cycloserine and lurasidone (1) raises Glx by a greater amount than either placebo or lurasidone alone in patients with bipolar depression, and (2) whether that elevation in Glx is correlated with a decrease in depression.

    Following study enrollment and randomization, subjects will undergo two treatment sessions, 3 days apart.

In one treatment session the subject will receive oral placebo and in the other treatment session the subject will receive oral NRX-101. Following the second treatment session, the subject will participate in a four week open study of NRX-101, at the end of which a third session of Magnetic Resonance Spectroscopy will be conducted.

    • Drug: NRX-101
    • Drug: Placebo

    Following study enrollment and randomization, subjects will undergo two treatment sessions, 3 days apart. Each treatment session will be conducted while the subject is undergoing Magnetic Resonance Spectroscopy to measure Glx in the ACC. In one treatment session the subject will receive oral lurasidone and in the other treatment session the subject will receive oral NRX-101. Following the second treatment session, the subject will participate in a four week open study of NRX-101, at the end of which a third session of Magnetic Resonance Spectroscopy will be conducted.

  8. In good general health, as ascertained by medical history, physical examination (including measurement of seated vital signs), clinical laboratory evaluations, and electrocardiogram
  9. If female, a status of non-childbearing potential or use of an acceptable form of birth control per the following specific criteria:

    1. Non-childbearing potential (e.g., physiologically incapable of becoming pregnant, i.e., permanently sterilized [status post hysterectomy, bilateral tubal ligation], or post-menopausal with last menses at least one year prior to screening); or
    2. Childbearing potential, and meets the following criteria:

    i. Using any form of hormonal birth control, on hormone replacement therapy started prior to 12 months of amenorrhea, using an intrauterine device (IUD), having a monogamous relationship with a partner who has had a vasectomy, or sexually abstinent.

    iii. Willing and able to continuously use one of the following methods of birth control during the course of the study, defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly: implants, injectable or patch hormonal contraception, oral contraceptives, IUD, double-barrier contraception, sexual abstinence. The form of birth control will be documented at screening and pre-ketamine baseline.
