Phase 1 |
Detailed Description
It is a 2-part study in hospitalized COVID-19 patients.
- Part 1 is to evaluate safety, tolerability, PK and markers of clinical activity of escalating doses of PF-07304814 given as 24-hour IV infusion.
2 planned and 3 optional cohorts with 8 participants each are planned.
- Part 2 is to evaluate safety, tolerability, PK and markers of clinical activity of escalating doses of PF- 07304814 given as 120-hour infusion.
2 planned and 2 optional cohorts with 8 participants each are planned
