CORRECTION: NeuroRx and Relief Announce Initial Successful Results from Expanded Access Use of RLF-100(TM) (aviptadil) in Patients with Critical COVID-19 and Severe Comorbidity: 72% Survival Seen in ICU Patients
Correction of the press release published November 24, 2020: It has come to our attention that a mistake was printed in the percentage of control patients in the EAP who survived to day 28. The correct percentage is
GENEVA, SWITZERLAND and RADNOR, PA / ACCESSWIRE / November 25, 2020 / RELIEF THERAPEUTICS Holding AG (SIX:RLF)(OTCQB:RLFTF) ("Relief" or the "Company") and NeuroRx, Inc., announced that more than 175 patients with Critical COVID-19 and Respiratory Failure who also have a severe comorbidity have now been entered into an Expanded Access Protocol (EAP) with RLF-100(TM) in the United States.
All patients had severe comorbidities (such as organ transplant, recent heart attack, and cancer) that rendered them ineligible for the ongoing randomized, controlled phase 2b/3 trial being conducted to ascertain safety and efficacy of RLF-100(TM), and all patients were deteriorating despite treatment with approved therapies for COVID-19 (see www.clinicaltrials.gov NCT 04311697). Of the 90 patients who have so far reached 28 days of follow-up,
As previously reported by Youssef and coworkers (http://dx.doi.org/10.2139/ssrn.3665228), at Houston Methodist Hospital, 21 patients treated with RLF-100(TM) under the EAP were compared to 24 control patients treated in the same setting. Only
Notably, in the EAP, no drug-related Serious Adverse Events have been reported to date among these patients nor the 160 patients randomized to RLF-100(TM) vs. placebo in the U.S. phase 2b/3 clinical trial currently underway. Thus, from a risk/benefit perspective, while the benefit of RLF-100(TM) has not yet been proven in a randomized prospective trial, no serious risk has been identified so far.
Currently, 25 U.S. hospitals have enrolled patients in the EAP, nearly all of which are community hospitals, suggesting that RLF-100(TM) can demonstrate effectiveness in the hands of front-line physicians who deliver the majority of care to patients with Critical COVID-19. Physicians enrolling patients in the EAP have routinely reported that initial patients at their sites have frequently been in the ICU for several weeks without recovery prior to treatment with RLF-100(TM). As patients are treated earlier in the course of their ICU stay, there is an emerging clinical impression that RLF-100(TM) has an even greater impact on recovery.
"We are reassured that emerging real-world data on the use of RLF-100(TM) in improving survival in patients with Critical COVID-19 are comparable to results seen in the hands of major academic teaching centers. We hope that these findings are viewed as encouraging at a time when many Americans, including the doctors, nurses, and other front-line caregivers who are the heart of our initiative, are celebrating the Thanksgiving holiday at a distance from their loved ones. We look forward to completing enrollment and reporting the results of our pivotal U.S. clinical trial," said Prof. Jonathan C. Javitt, MD, MPH, CEO and founder of NeuroRx, Inc.

ABOUT VIP IN LUNG INJURY
Vasoactive Intestinal Polypeptide (VIP) was first discovered by the late Dr. Sami Said in 1970. Although first identified in the intestinal tract, VIP is now known to be produced throughout the body and to be primarily concentrated in the lungs. VIP has been shown in more than 100 peer-reviewed studies to have potent anti-inflammatory/anti-cytokine activity in animal models of respiratory distress, acute lung injury, and inflammation. Most importantly,
COVID-19-related death is primarily caused by respiratory failure. Before this acute phase, however, there is evidence of early viral infection of the alveolar type 2 cells. These cells are known to have angiotensin converting enzyme 2 (ACE2) receptors at high levels, which serve as the route of entry for the SARS-CoV-2 into the cells. Coronaviruses are shown to replicate in alveolar type 2 cells but not in the more numerous type 1 cells. These same type 2 alveolar cells have high concentrations of VIP receptors on their cell surfaces giving rise to the hypothesis that VIP could specifically protect these cells from injury.
Injury to the type 2 alveolar cells is an increasingly plausible mechanism of COVID-19 disease progression (Mason 2020). These specialized cells replenish the more common type 1 cells that line the lungs. More importantly, type 2 cells manufacture surfactant that coats the lung and are essential for oxygen exchange. Other than RLF-100(TM), no currently proposed treatments for COVID-19 specifically target these vulnerable type 2 cells.
ABOUT RLF-100(TM)
RLF-100(TM) (Aviptadil) is a formulation of Vasoactive Intestinal Polypeptide (VIP) that was developed based on Dr. Sami Said's original work at Stony Brook University, for which Stony Brook was awarded an FDA Orphan Drug Designation in 2001. VIP is known to be highly concentrated in the lungs, where it inhibits coronavirus replication, blocks the formation of inflammatory cytokines, prevents cell death, and upregulates the production of surfactant. FDA has now granted IND authorization for intravenous and inhaled delivery of RLF-100(TM) for the treatment of COVID-19 and awarded Fast Track designation. RLF-100(TM) is being investigated in two placebo-controlled US Phase 2b/3 clinical trials in respiratory deficiency due to COVID-19. Since July 2020, more than 150 patients with Critical COVID-19 and Respiratory Failure have been treated with RLF-100(TM) under FDA-approved protocols.
