Look at NASH phase 2 trials - they take long time and one is competing with big players in same space.
They will need phase 2B and phase 3 or phase 2B/3 with large no of patients and min 48 week trial - if you add timelines, 2023 is too early. Look at MDGL and VKTX or GILD current or past trials and their timelines
I can’t say for sure and would admittedly be a guess. Combo HIV was about 4-5 years... so if we just injected first patient for NASH, it could be 2023.
Based on that first patient for COVID-19 won't be until 2022.
