FDA grants Expanded Access Protocol to RLF-100 (Aviptadil) for Respiratory Failure in COVID-19

Share

RELIEF THERAPEUTICS Holding AG (SIX:RLF, OTC:RLFTF) “Relief” and its U.S. partner, NeuroRx, Inc. today announced that FDA has granted an Expanded Access Protocol for treatment of Respiratory Failure in COVID-19 with RLF-100 (aviptadil), a synthetic form of Vasoactive Intestinal Peptide (VIP). The protocol makes treatment available to patients who have exhausted standard therapies and are not eligible for the current phase 2/3 trial of RLF-100 because of confounding medical conditions and specifically makes the treatment available to pregnant women. Although the drug remains under investigation, rapid recovery from respiratory failure in COVID-19 has been seen in patients treated under FDA Emergency Use authorization.1

The expanded access protocol may be viewed on www.clinicaltrials.gov NCT04453839. Physicians who wish to enroll their patients in the protocol must submit the protocol to their local investigational review board and file FDA form 1572 with NeuroRx, Inc. Further information may be obtained from expandedaccess@neurorxpharma.com.

“By granting this Expanded Access protocol, FDA has made a potentially lifesaving drug immediately available to critically ill patients who have no other available treatment,” said Dr. Jonathan C. Javitt, MD, MPH, NeuroRx’s CEO. “We thank the FDA’s pulmonary division for its rapid and proactive implementation of the Coronavirus Treatment Acceleration Program, and we aspire to demonstrate broad safety and efficacy for RLF-100 in our ongoing clinical trial.”

The SARS-CoV-2 coronavirus that causes COVID-19 attacks the body by entering the small population of Alveolar Type II cells in the lung.2 Without Type II cells, the lung cannot transmit oxygen, which why the coronavirus causes acute respiratory failure. 50 years of scientific research demonstrates that VIP binds specifically to the Type II cell and protects that cell against cytokines (inflammatory molecules) and a wide array of toxic and infectious injuries.”3
