ABOUT RLF-100^TM

RLF-100^TM (aviptadil) is a synthetic form of Vasoactive Intestinal Peptide (“VIP”) consisting of 28 amino acids, which was first discovered in 1970. Although initially identified in the intestinal tract, human VIP is known to be produced throughout the body and to be primarily concentrated in the lungs where it has shown a multimodal mechanism of action: specifically, a decrease of inflammatory cytokines release leading to prevention of cytokine storm syndrome and viral replication, an immunomodulating effect, vasodilating and broncho-dilating effects, and prevention of surfactant depletion (surfactant coats the inside of the lungs, which can be lost during COVID-19 and lead to respiratory failure). Seventy percent of VIP in the body is bound to a less common type of cell in the lung, the alveolar type 2 cell, which is critical to the transmission of oxygen to the body.

RLF-100^TM has a 20-year history of safe use in humans in multiple human trials for sarcoidosis, idiopathic pulmonary fibrosis, asthma, pulmonary arterial hypertension, and sepsis-induced acute respiratory distress syndrome. A combination of aviptadil with phentolamine is approved for the treatment of erectile dysfunction by intra-cavernous injections in countries outside the U.S.

RLF-100^TM is currently late-stage clinical testing in the U.S for acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) associated with the SARS-CoV-2 virus (COVID-19) through Relief’s collaboration partner in the U.S., NeuroRx, Inc. VIP has been granted Fast Track Designation by FDA for the treatment of critical COVID-19 patients with respiratory failure. Relief is also focused on RLF-100^TM for the treatment of, among other indications, COVID-19 non-acute lung injury, non-COVID-19 related ARDS, checkpoint inhibitor-induced pneumonitis and pulmonary sarcoidosis.
