Study Details

Study Description

Brief Summary

The current study is the second clinical administration with PF-07304814, the phosphate prodrug of the active moiety PF-00835231, and the first in healthy adult participants. It is to evaluate safety, tolerability and PK of single escalating doses of PF 07304814 given as a 24-h IV infusion.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

The current study is the second clinical administration with PF-07304814, the phosphate prodrug of the active moiety PF-00835231, and the first in healthy adult participants. It is to evaluate safety, tolerability and PK of single escalating doses of PF 07304814 given as a 24-h IV infusion. This is a randomized, double-blind, sponsor-open, placebo-controlled trial. There will be 2 cohorts with a total of approximately 16 participants planned (approximately 8 participants in each cohort).
