Relief Affirms Initiation of Phase 2/3 Trial of Inhaled RLF-100(TM) (Aviptadil; ZYESAMI(TM)) in Severe COVID-19 Patients

• Top-line data from intravenous RLF-100(TM) phase 2b/3 trial expected to be released this month

Geneva, Switzerland, February 08, 2021 - RELIEF THERAPEUTICS Holding AG (SIX: RLF, OTCQB: RLFTF) ("Relief" or the "Company") affirms that its collaboration partner NeuroRx, Inc. has initiated a phase 2/3 clinical trial investigating the role of inhaled RLF-100^TM (aviptadil; ZYESAMI(TM)) for the treatment of patients with severe COVID-19 in partnership with UCI Health of the University of California, Irvine. The objective of the current study is to determine whether RLF-100^TM, administered at the earlier (severe) stage of COVID-19 can reduce the likelihood of progression to critical COVID-19 with respiratory failure: the predominant cause of death in COVID-19-infected individuals.

The statistical analysis of the data remains ongoing. Relief expects top-line data from this trial to be reported once the required statistical analyses have been completed.
