Montgomery Asberg Depression Rating Scale Total Score
Clinical Global Impression Suicidality Scale
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
Mean change in Glx Area Under the Curve (AUC) measured in 15 minute increments over 2 hours at following experimental drug vs. comparator
The study will measure the difference on BISS-derived MADRS score between NRX-101 and lurasidone (comparator) groups. The Bipolar Inventory of Symptom Scale (BISS) is a validated 42-item clinician-rated scale (21 items each for the depression and mania subscales) in which each item is rated on a 0-4 severity scale where higher values indicate worse severity. BISS-derived MADRS (BDM): MADRS is a 10-item clinician-rated scale, with each item rated on a 0-6 severity scale, where a higher number indicates worse severity. Responses to each question are equally weighted and summed. The BDM has a minimum score of 0 and a maximum of 40, where higher scores indicate a worse severity, therefore decreases in average BDM are considered a better outcome. Data are presented as mean change from baseline (end of stage 1, Day 1) using LOCF

|---|---|---|
| Transcranial Magnetic Stimulation plus NRX-101 | EXPERIMENTAL | Participants are treated with ONE-D TMS plus NRX-101 175mg DCS/8.5mg Lurasidone once daily for five days |
| Transcranial Magnetic Stimualtion | PLACEBO_COMPARATOR | Participants are treated with ONE-D TMS plus placebo once daily for five days |
| Sham TMS + NRX-101 | EXPERIMENTAL | Participants will be treated with Sham TMS (i.e. a TMS coil that does not deliver effective energy to the brain) + NRX-101 |
| NRX-101 | EXPERIMENTAL | Following study enrollment and randomization, subjects will receive twice daily NRX-101 |
| Lurasidone | ACTIVE_COMPARATOR | Following study enrollment, subjects will receive twice daily lurasidone |
| NRX-101 vs. Placebo | EXPERIMENTAL | 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 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. |
| NRX-101 vs. lurasidone HCl | EXPERIMENTAL | 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. |

NRX-101 is an investigational small molecule being developed for treatment resistant depression and bipolar depression. It is currently in Phase 2 clinical development and has been studied in patients with bipolar depression with suicidal ideation. The drug is being evaluated for its ability to treat these psychiatric conditions.
NRX-101 is being developed by NRX Pharmaceuticals, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol NRXP. The company is conducting clinical trials of NRX-101 in the United States for psychiatric indications including bipolar depression and treatment resistant depression.
NRX-101 is in Phase 2 clinical development. It has received Breakthrough Therapy designation from the FDA. The drug is investigational and has not been approved by the FDA. Multiple Phase 2 trials have been completed, and an additional Phase 2 trial is planned but has not yet begun recruiting patients.
NRX-101 has been studied in several clinical trials. Completed Phase 2 trials include NCT02974010 for severe bipolar depression, NCT03395392 for bipolar depression with subacute suicidal ideation, and NCT03402152, a biomarker validation study. A new Phase 2 trial, NCT07227103, is planned for treatment resistant depression using robotic transcranial magnetic stimulation.
NRX-101 is the primary name used for this investigational drug in clinical trials and by its developer, NRX Pharmaceuticals. No alternative names have been reported for this compound in the available clinical trial information.
NRX-101 is a small molecule being studied for its effects on depression. The specific molecular target of NRX-101 has not been disclosed in the available information. Clinical trials are evaluating its efficacy in treating bipolar depression and treatment resistant depression, including in patients with suicidal ideation.
