Animal testing is used to demonstrate efficacy using a delivery method into a system that is much more similar to a human than a cell culture.
It's much cheaper to run a few animal tests rather than diving into clinical trials with only cell culture results.
This other molecule demonstrated that. I was pointing out that BIzzy's assumption may not be accurate since we had not done that yet and the two molecules are not related.
Per this statement we are going straight to clincal trial- "Given the safety and efficacy data already known about Brilacidin from pre-clinical and clinical studies utilizing multiple routes of administration, a Phase 2 clinical trial of intravenously-administered Brilacidin for COVID-19 is being planned, with a trial initiation targeted for the fourth quarter of calendar year 2020. Partnering opportunities with industry and academic partners are ongoing regarding COVID-19".
