Study Details

Study Description

Brief Summary

It is Phase 1b, 2-part, double-blind, placebo-controlled study to evaluate safety, tolerability, and pharmacokinetics of PF-07304814, in patients hospitalized with SARS-CoV-2 virus infection.

Condition or Disease Intervention/Treatment Phase
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

26 participants
Allocation:
Randomized
Intervention Model:
Sequential Assignment
Intervention Model Description:
Part 1 will have 2 planned cohorts. Each escalating cohort will be initiated for enrollment after assessment of safety, tolerability and PK data from previous cohorts by an independent IRC and is deemed acceptable. Part 2 will have 2 planned cohort and each escalating cohort will be initiated after all safety, tolerability and PK data from previous cohort is evaluated and is deemed acceptable by a competent regulatory authority.Part 1 will have 2 planned cohorts.
