Company to Host Conference Call and Webcast August 15, 2022, at 8:30am ET

RADNOR, Pa., Aug. 15, 2022 /PRNewswire/ -- NRx Pharmaceuticals, Inc. (NASDAQ:NRXP), ("NRx Pharmaceuticals" or the "Company"), a clinical-stage biopharmaceutical company, today announced its financial results for the second quarter of 2022 and provided a business and clinical update.

Newly Appointed Proven Bio CEO, Stephen Willard, Leads Q2-22 Earnings Report & Reinitiated Franchise Focus in Psychiatry

"During our second quarter, we reactivated clinical development in our psychiatry franchise around our lead compound, NRX-101. NRX-101 has been awarded Breakthrough Therapy designation and a Special Protocol Agreement for severe bipolar depression with acute suicidal ideation and behavior (ASIB) by the U.S. Food and Drug Administration (FDA), said Stephen Willard, Chief Executive Officer of the Company. "We anticipate initiation of the study in severe bipolar depression with acute suicidal ideation and behavior (ASIB) to commence at the end of 2022 or at the beginning of 2023.

During this quarter, we commenced enrollment in our Phase 2 trial of NRX-101 in patients with Bipolar Depression and Sub-Acute Suicidal Ideation & Behavior (SSIB)", said Willard. "The purpose of this trial is to expand our potential indication from bipolar depression in patients with acute suicidality to the significantly larger population of patients with bipolar depression and sub-acute suicidality, who are being treated in the ambulatory setting. We are evaluating the adequacy of the protocol to support approval for the treatment of the larger SSIB population. We project a readout of the data from this trial by the end of the year or early Q1 of next year".

"We expect to release commercial-stage material of NRX-101 in the coming weeks. This material will be used in our phase 2b/3 trial of NRX-101 for severe bipolar depression in patients with acute suicidal ideation & behavior (ASIB) under the FDA Special Protocol Agreement, which we expect to start in Q4," said Mr. Willard.

Many approved drugs for bipolar depression have warning labels for increased risk of suicide. To our knowledge, NRX-101 is the only oral antidepressant in the bipolar segment that targets patients with active suicidality, which typically is an exclusion criterion in clinical studies of depression and PTSD. Phase 2 STABIL-B trial¹ data of NRX-101 demonstrated a significant reduction in both depression and suicidality compared to standard therapy in acutely suicidal patients who were first stabilized with ketamine. We have released non-clinical findings demonstrating that, unlike ketamine, both components in NRX-101 have not shown potential for addiction and are not neurotoxic (i.e., do not cause death of brain cells in FDA-required assays).²

In Q2, we repatriated the manufacture of NRX-101 drug supply to North Carolina and are currently manufacturing clinical supplies for P3 as part of the commercial readiness program.

Our psychiatry franchise builds on a strong scientific and intellectual property foundation with 47 granted patents and 43 pending applications around the world. Our focus is to address this major unmet medical need for which the only currently approved treatment is electroshock therapy. It is estimated that 50% of individuals with bipolar disorder attempt suicide over their lifetime. We believe NRX-101 is a potentially life-saving medicine that could change the treatment paradigm for individuals with bipolar depression that are also experiencing suicidality."

We expect to evaluate the options for ZYESAMI® in COVID-19 Respiratory Failure and other lung disorders once we receive the full data set from NIH towards the end of Q3 or early Q4 and have conducted our own analysis.

Although we are not funding additional clinical trials of ZYESAMI^® at this time, we have completed manufacture of phase 3/commercial ready ZYESAMI^®. We also received an independent assessment of chest X-ray data from a sub-study that included a subgroup of approximately 80 patients that had survived to day 10 in our Phase 2b/3 study of ZYESAMI®. The sub-study showed a statistically significant improvement in chest X-rays using the RALES score in patients with COVID-19 respiratory failure, compared to a worsening in patients treated with placebo (P<.05). This exploratory data will further guide our assessment of future options for ZYESAMI®.

Key Business & Clinical Highlights

Announced new leadership with the appointment of Stephen Willard, JD, as CEO and member of the Board of Directors, and Seth Van Voorhees, PhD, MBA, as CFO
Repositioned company to focus on psychiatry franchise and our Breakthrough Therapy designated drug NRX-101 for Bipolar Depression in Patients with Suicidality. NRX-101 has additionally been awarded a Special Protocol Agreement by the FDA
Repatriated manufacture of NRX-101 to a leading North Carolina-based manufacturer, completed technology transfer, and manufactured first batch of phase 3/commercial-ready NRX-101 capsules
Initiated a Phase 2b trial of NRX-101 in patients with Bipolar Depression and Sub-Acute Suicidality (SSIB); 10 planned clinical sites are activated and are actively enrolling patients, with topline data readout anticipated at the end of Q4 22/Q1 23
Received independent grading of chest x-rays from a subgroup of patients that survived to day 10 from the intravenous ZYESAMI^® trial. Top line analysis shows a statistically significant change between baseline and day 10 on the RALES score (i.e., improvement in ZYESAMI^®-treated patients and worsening in placebo-treated patients). Ongoing data analysis is continuing.

Financial Results for Quarter ended June 30, 2022

Research and development expenses for the three months ended June 30, 2022, totaled $3.0 million, compared to $4.7 million for the quarter ended June 30, 2021. The decrease of $1.7 million related primarily to a decrease clinical trials and development expenses related to ZYESAMI^®.
General and administrative expenses for the three months ended June 30, 2022, totaled $6.6 million, compared to $12.5 million for the three months ended June 30, 2021. The decrease of $5.8 million was primarily related to a decrease in stock-based compensation and consultant fees, partially offset by an increase in higher insurance related expenses.
Other income for the three months ended June 30, 2022, totaled $2.6 million, compared to $17.0 million for the three months ended June 30, 2021. The decrease of $14.4 million primarily related to a decrease in the fair value of certain Substitute Warrants and the Placement Warrants assumed pursuant to the Merger Agreement because of lower stock price levels.
Net loss for the three months ended June 30, 2022, was $7.0 million compared with a net loss of $0.1 million for the three months ended June 30, 2021.

Financial Results for Six Months ended June 30, 2022

Research and development expenses for the six months ended June 30, 2022, totaled $8.4 million, compared to $7.6 million for the six months ended June 30, 2021. The increase of $0.9 million related primarily to an increase in regulatory and process development expenses.
General and administrative expenses for the six months ended June 30, 2022, totaled $16.9 million, compared to $14.6 million for the six months ended June 30, 2021. The increase of $2.3 million was primarily related to an increase in legal, professional and insurance expenses partially offset by a decrease in consultant fees and stock-based compensation expenses.
Other Income for the six months ended June 30, 2022, totaled $4.9 million, compared to $17.1 million for the recently restated six months ended June 30, 2021. The decrease of $12.2 million primarily related to a decrease in the fair value of certain Substitute Warrants and the Placement Warrants assumed pursuant to the Merger Agreement because of lower stock price levels.
Net loss for the six months ended June 30, 2022, was $20.4 million compared with a net loss of $25.6 million for the three months ended June 30, 2021.
As of June 30, 2022, cash was $24.5 million compared to $27.6 million as of December 31, 2021. We believe that we have sufficient funds and if necessary, the ability to reduce expenditures, to support operations through August 2023. The Company may also seek to reduce certain expenditures if needed to reduce cash consumption in support of operations.

About NRX-101

Up to 50% of individuals with bipolar disorder attempt suicide over their lifetime, and estimates indicate that up to 20% may succumb to suicide. The only FDA-approved treatment for patients with bipolar depression and acute suicidal ideation & behavior (ASIB) remains electroconvulsive therapy (ECT). Conventional antidepressants can increase the risk of suicide in certain patients; hence their labels contain a warning to that effect. NRX-101 is a patented, fixed dose combination of D-cycloserine and lurasidone, neither of which has shown addiction potential. Based on the results of a Phase II study, NRX-101 received Breakthrough Therapy designation (BTD) from the FDA for the Treatment of Severe Bipolar Depression in Patients with ASIB after initial stabilization with ketamine or other effective therapy.

NRX-101 is one of the first oral antidepressants currently in late-stage clinical studies targeting the NMDA-receptor in the brain, which represents potentially a key new mechanism to treat depression with and without suicidality, as well as PTSD and other indications. To date, NRX-101 is the only oral NMDA investigational medicine focused on bipolar depression in patients with acute and sub-acute suicidality.

NRx Pharmaceuticals expects to begin its registration trial for NRX-101 under a SPA in 4Q 2022.
