- Based on a review of nearly 75% of the target enrollment of 640 patients, most of which have reached 90 days, the Independent DSMB overseeing the ACTIV-3b (TESICO) study determined that evaluation of aviptadil should cease due to futility
- ZYESAMI® (aviptadil) was the sole remaining investigational medicine in ACTIV-3b targeted at Critical COVID-19 patients
- ACTIV-3b Critical Care Study evaluated ZYESAMI and Veklury® (remdesivir), in Critical COVID-19 Patients, as monotherapy and in combination against placebo
- The DSMB stated there were no safety concerns for aviptadil
RADNOR, Pa., May 25, 2022 /PRNewswire/ -- NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) (“NRx Pharmaceuticals”), a clinical-stage biopharmaceutical company, today announced results of a review conducted by the Data Safety and Monitoring Board (DSMB) on May 25, 2022. The DSMB reviewed data of approximately 460 patients with Critical COVID-19 Respiratory Failure who were enrolled in the ACTIV-3b (TESICO) trial, most of which had reached the 90-day endpoint. The trial is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
The DSMB recommended stopping further randomization to aviptadil due to aviptadil not meeting the futility guidelines outlined by the pre-approved analytical plan. The primary endpoint (90 day 6-category ordinal score) was not supportive (OR 1.10; 0.79 – 1.54; p=0.56), and 90-day mortality secondary endpoint was also not supportive with 37% mortality in the aviptadil group vs 36% in the placebo group; HR 1.04 (0.77-1.41); p=0.79. There were no safety concerns, the known side effects of aviptadil (principally diarrhea and hypotension) were managed well with the protocols in place.
“We thank the NIH and the Trial Leadership for its extensive work in studying ZYESAMI® (aviptadil). We will continue to work closely with them to better understand the data over the coming months. This will also enable us to evaluate the options for ZYESAMI® in protecting the lung in other respiratory disorders, as well as its potential in other therapeutic areas,” said Robert Besthof, Interim CEO of NRx Pharmaceuticals. “Critical COVID-19 remains a very high unmet need associated with significant mortality. “
“Our corporate focus remains to apply innovative science to known molecules in order to address very high unmet needs. We have a flexible infrastructure that allows us to focus our resources on our Breakthrough Therapy designation drug NRX-101. We are already actively enrolling patients in our Phase II study for bipolar depression in patients with Sub-acute Suicidal Ideation & Behavior (SSIB) and in the second half of the year we intend to start our Phase IIb/III registrational study for Severe Bipolar Depression in Patients with Acute Suicidal Ideation and Behavior (ASIB). “
