ABOUT RELIEF
Relief focuses primarily on clinical-stage programs based on molecules of natural origin (peptides and proteins) with a history of clinical testing and use in human patients or a strong scientific rationale. Currently, Relief is concentrating its efforts on developing new treatments for respiratory disease indications. Its lead drug candidate RLF-100(TM) (aviptadil), synthetic vasoactive intestinal peptide (VIP), is being investigated, in cooperation with NeuroRx Inc., in two placebo-controlled U.S. Phase 2b/3 clinical trials in respiratory deficiency due to COVID-19. RLF-100(TM) is believed to be the first COVID-19 therapeutic to demonstrate the ability to block replication of the SARS-CoV-2 virus in human lung cells and monocytes, while also preventing synthesis of cytokines in the lung. Since July 2020, severe COVID-19 patients have been treated with RLF-100(TM) under U.S. FDA Emergency Use Investigational New Drug (IND) authorization and Expanded Access Protocol authorization for the treatment of respiratory failure in COVID-19. Relief also holds a patent issued in the United States and various other countries covering potential formulations of RLF-100(TM).
