Relief, with Partner NeuroRx, Announces Enrollment of 150 Patients in Phase 2b/3 Trial of RLF-100(TM) for Critical COVID-19 with Respiratory Failure
Relief Therapeutics, in collaboration with NeuroRx, has enrolled 150 patients in a phase 2b/3 trial for RLF-100(TM), targeting respiratory failure in critical COVID-19 cases. The trial aims to assess the drug's effectiveness, with no serious adverse events reported thus far. An earlier study indicated a significant survival advantage linked to RLF-100(TM). Additionally, main shareholder GEM has exercised 500 million warrants, increasing Relief's cash balance to approximately CHF 49.8 million.
- Enrollment of 150 patients in phase 2b/3 trial for RLF-100(TM), nearing target of 165.
- No drug-related serious adverse events reported, indicating safety of RLF-100(TM).
- Previous studies show a nine-fold hazard ratio advantage in survival and recovery for patients treated with RLF-100(TM).
- Main shareholder GEM exercised 500 million warrants, boosting cash reserves to approximately CHF 49.8 million.
- Enrollment delayed due to COVID-19 impact on hospital capacities.
- Observations of rapid recovery on chest x-rays noted and no drug-related Serious Adverse Events reported
- Relief also reports exercise of 500 million warrants by main shareholder GEM
GENEVA, SWITZERLAND / ACCESSWIRE / November 13, 2020 / RELIEF THERAPEUTICS Holding AG (SIX:RLF)(OTCQB:RLFTF) ("Relief" or the "Company") with its partner NeuroRx, Inc., announced that as of today, 150 patients (out of a targeted enrollment of 165) have been enrolled in the ongoing phase 2b/3 trial of RLF-100(TM) (aviptadil) for treating respiratory failure in patients with critical COVID-19. Respiratory failure is defined, according to FDA guidance, as the need for intensive care with mechanical ventilation, non-invasive ventilation, or high-flow nasal oxygen in order to sustain adequate levels of blood oxygen. So far, no drug-related serious adverse events have been reported.
There is currently no FDA-approved drug that has shown efficacy in patients who are already in the Intensive Care Unit (ICU) with Respiratory Failure. Although NeuroRx and Relief are optimistic that RLF-100(TM) will also be effective in treating early COVID-19, the companies have focused first on those patients who have no available therapy and are at the highest risk of mortality. An open-label prospective study in patients with Critical COVID-19 has already shown a nine-fold hazard ratio advantage in both survival and recovery from respiratory failure (http://dx.doi.org/10.2139/ssrn.3665228) with both statistically significant (P < .001). More than 110 patients with similar severity have additionally been treated nationwide under an FDA-sanctioned Expanded Access Protocol (NCT04453839).
Although the phase 2b/3 study remains blinded, illustrative blinded recoveries from signs of Critical COVID-19 on Chest x-ray within 10 days have been reported by study sites and shared with the study's Data Monitoring Committee and FDA. Until the study is unblinded, it cannot be known whether this rapid recovery was more frequent among patients treated with RLF-100(TM) compared to those treated with placebo. However, in the open-label prospective study, more rapid recovery was seen among 21 patients treated with RLF-100TM than those treated with standard of care with an average of nine fewer ICU days in the RLF-100TM treated patients compared to those treated with Standard of Care.
Completion of enrollment is anticipated in the coming weeks. Enrollment was uniquely challenged by the devastating effects of the pandemic. It strained the capacity of hospitals and caused the temporary incapacity of investigators and study coordinators at several study sites, who themselves contracted COVID-19 in the course of their duties.
"Should RLF-100(TM) prove to be safe and effective for treating COVID-19 Respiratory Failure, the nation will owe an eternal debt of gratitude to the front-line healthcare workers, technicians, study coordinators, nurses, and doctors who worked seven days a week to help develop this treatment while risking their own health to do so. They are the true heroes," said Prof. Jonathan Javitt, CEO and founder of NeuroRx, Inc.
GEM Exercises Warrants
Relief also reported today that the Company's main shareholder, GEM Global Yield LLC SCS ("GEM"), has exercised 500 million warrants. GEM has 86.66 million warrants remaining in Relief. Following this exercise, Relief's available cash balance totals approximately CHF 49,800,000. Upon issuance of the shares, the total amount of shares outstanding will be 3,160,068,581.
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 alveolar type 1 cells. These same alveolar type 2 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 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, alveolar 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 alveolar type 2 cells.
ABOUT RLF-100(TM)
RLF-100(TM) (Aviptadil) is a formulation of Vasoactive Intestinal Polypeptide (VIP) that was developed based on Prof. 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.
