Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).
