RADNOR, Pa., July 29, 2024 /PRNewswire/ -- NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) ("NRx Pharmaceuticals", the "Company"), a clinical stage pharmaceutical company, today announced a communication from the US Food and Drug Administration (FDA) providing feedback and alignment on NRx's proposed initial Pediatric Study Plan (iPSP) for NRX-100 (ketamine) in the treatment of suicidal depression. Congress required the submission of an iPSP as a precondition to filing a New Drug Application in the 2012 Food and Drug Administration Safety and Innovation Act (FDASIA).[1]

Suicide is a growing crisis among adolescents in the United States. According to the US Centers for Disease Control, 10% of high school students attempted suicide in the past year and 22% of high school students reported having seriously considered suicide. This percentage is highest among females (30%), American Indians/Alaska Natives (27%), and lesbian, gay, or bisexual teens (45%) (CDC, 2023). [2]
In support of its upcoming NDA filing, NRx will be submitting existing data supporting the safety and efficacy of ketamine to treat suicidal depression in adults. FDA has now documented its recognition that suicide is a serious and growing public health concern in adolescents as well. Based on the guidance received, NRx and HOPE Therapeutics will commit to conducting a clinical trial of NRX-100 in adolescents aged 9-17 with suicidal depression, but will not be required to study the effects of NRX-100 in younger age groups, following initial approval of NRX-100 in adults. Additional neurotoxicity studies will be conducted in juvenile animal subjects to support the safety of intravenous ketamine in this younger population.
"Youth suicide has reached crisis proportions in the United States with a 62% increase over the past two decades, disproportionately affecting minorities.[3] We appreciate FDA's recognition of the urgent unmet medical need related to suicidal depression in adolescents and look forward to expanding the mission of NRx and HOPE Therapeutics to serve America's youth in preventing needless deaths from suicidal depression, said Prof. Jonathan Javitt, Chairman of NRx Pharmaceuticals and Co-CEO of HOPE Therapeutics."
