Initial results have been presented by Relief’s partner, NeuroRx, Inc.; additional statistical analyses remain ongoing and shall be presented when complete 

Geneva, Switzerland, February 10, 2021 –RELIEF THERAPEUTICS Holding AG (SIX: RLF, OTCQB: RLFTF)(“Relief”), a biopharmaceutical company with its lead compound RLF-100™ (aviptadil) in advanced clinical development to treat severe COVID-19 patients, today announced the release of preliminary results from the phase 2b/3 trial of intravenously administered RLF-100™ by its partner NeuroRx, Inc.

NeuroRx announced yesterday preliminary findings from the phase 2b/3 trial of the intravenous delivery form of RLF-100™. According to NeuroRx, the preliminary data suggest that the administration of intravenous RLF-100™ could reduce the length of hospital stay among patients with respiratory failure due to critical COVID-19 compared to placebo plus maximal standard of care. No unexpected side effects were identified. The most common side effects of RLF-100™ in the clinical trial were mild to moderate diarrhea and systemic hypotension (low blood pressure). All potentially serious adverse effects were investigated by a board-certified critical care physician together with site investigators; none were deemed drug related.

The statistical analysis of the day 28 data is ongoing; final top-line data from the phase 2b/3 trial of intravenous RLF-100™ shall be reported once the analyses have been completed.

The trial is also continuing to further assess the effects of RLF-100™ up to day 60. These data shall be reported once they become available.
