- FDA response highlights the importance of addressing suicidal
depression in adolescents age 9-17
- Alignment on initial Pediatric Study Plan (iPSP) is a gating
requirement for the upcoming filing of an NRX-100 New Drug
Application (NDA) for suicidal depression
- NRx remains on track to file the NDA for NRX-100 in Q4 2024
with anticipated PDUFA date in Q2 2025
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."
