- New Drug Application (NDA) for Accelerated Approval planned for NRX-101 in people with bipolar depression and akathisia in 2024, based on two positive trials 1 2 and Breakthrough Therapy Designation. Potential revenue in 2025
- NDA for NRX-100 (IV ketamine) in suicidal depression in advanced preparation for submission in 2024; based on four positive trials 3 4 5 6 and Fast Track Designation. Potential revenue in 2025
- Gaining these approvals has the potential to yield more than $150 in revenue per NRXP share in the near term, at current share count
- Planning for HOPE Therapeutics share distribution progresses; audit nearing completion – critical step towards a public listing
NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) ("NRx Pharmaceuticals", the "Company"), a clinical-stage biopharmaceutical company, today announced that advice from regulatory counsel, which includes former senior officials from the Food and Drug Administration, supports filing two New Drug Applications (NDAs) in 2024: an application for Accelerated Approval for NRX-101 to treat bipolar depression in patients with akathisia and an application for approval of NRX-100 (IV ketamine) for treatment of suicidal depression.
While efficacy and safety data are now in hand, filing of the above applications is dependent upon completion of 12-month stability data in manufactured lots as required by FDA regulations.
As disclosed in an 8K filing, NRx will be filing the NRX-101 application without a commercial partner. The addressable market for the accelerated approval indication is such that a compact and efficient salesforce can be constructed by a small company, such as NRx, and current executives at NRx have previously held primary responsibility for launch of similar-sized pharmaceutical assets.
NRx continues work to enable the distribution of shares in Hope Therapeutics. This distribution is dependent upon completion of a public audit and successful review of an SEC Form 10.
"The NRx team has worked diligently since the end of the COVID pandemic to achieve these milestones for our shareholders and most importantly the patients we have always sought to help," said Dr. Jonathan Javitt, Chairman and Chief Scientist of NRx. "Given the near-term market opportunity represented by an accelerated approval process, NRx anticipates a higher potential return to NRx investors associated with an NRx-led initiative than that which would likely be achieved with a large commercial partner."
NRX-101 for Bipolar Depression
NRX-101 is the Company's patented (Composition of Matter), oral combination of the NMDA antagonist D-cycloserine and lurasidone for bipolar depression. Data from two active control clinical trials vs. the standard of care, lurasidone, have shown comparable antidepressant efficacy with clinically important reductions in suicidality and/or akathisia. To the Company's knowledge, no other oral agent has demonstrated such a valuable profile.
Up to 15% of people treated with drugs in lurasidone's class develop akathisia7; this would constitute an estimated $3.7 billion initial market for NRX-101, with no approved medicines for akathisia. This is a population the Company can readily address without a large commercial partner, given the relatively small number of psychiatrists who treat high-risk patients. The broad bipolar market constitutes 7 million people and an opportunity greater than $20 billion per year. With a best-in-class product profile, the Company projects NRX-101 sales in excess of $2 billion.
NRX-101 was awarded Breakthrough Therapy Designation, Fast Track Designation, a Biomarker Letter of Support, and a Special Protocol Agreement by the FDA for treatment of suicidal bipolar depression.
NRX-100 (IV ketamine) for Suicidal Depression
Intravenous ketamine is widely accepted as a standard of care for acute treatment of suicidal depression, in the absence of an FDA-labeled product; the only treatment currently approved by FDA is electroconvulsive therapy (ECT).
According to the CDC, 3.5 million Americans make a plan for suicide each year.8 This represents a $3-5 billion market at expected pricing.
Based on the data in the trials referenced above, the Company's regulatory counsel has encouraged the Company to file an NDA for suicidal depression for NRX-100. This application has been in development and awaits 12-month stability data for filing, which is expected in 2024.
