Study Details

Study Description

Brief Summary

The purpose of this clinical trial is to learn about the safety and effects of study medicine PF-07264660 compared to a placebo. This is the first study of PF-07264660 in humans. All participants in this study will received PF-07264660 or a placebo and it will be assigned by chance. People may be able to participate if they are healthy. The study medicine may be given by shots under the skin or through a vein depending on which group you are assigned to. If you are assigned into Part A, you will receive the study medicine once, stay overnight at the research unit from 3 to 5 overnight stays and you will need to visit the clinic about 11 follow-up visits. Participants will be in this study for up to about 541 days. If you are assigned into Part B, you will receive the study medicine three times, stay overnight at the clinic from 3 to 5 overnight stays and you will need to visit the research unit about 12 follow-up visits. Participants will be in this study for up to about 561 days.

Condition or Disease	Intervention/Treatment	Phase
Healthy Volunteers	Drug: PF-07264660 intravenous single ascending dose Drug: PF-07264660 subcutaneous multiple ascending dose Other: Intravenous placebo Other: subcutaneous placebo	Phase 1

Detailed Description

This is an first-in-human within-cohort randomized, participant- and investigator-blind, sponsor-open, placebo-controlled study of the safety, tolerability, pharmacokinetics, and pharmacodynamics following single ascending dose and multiple ascending dose.

PF-07264660 that will be conducted in healthy adults. Up to approximately 67 participants will be enrolled into the study and randomly assigned to receive PF-07264660 or placebo. This will include up to approximately 43 healthy participants (including 5 optional Japanese participants) in Part A, and up to approximately 24 healthy participants (including 8 participants in optional multiple ascending dose cohort) in Part B.

Study Design

Study Type:

Interventional

Anticipated Enrollment :

75 participants

Allocation:

Randomized

Intervention Model:

Parallel Assignment

Masking:

Triple (Participant, Care Provider, Investigator)

Masking Description:

Investigators and other site staff will be blinded to participants' assigned study intervention. Participants will be assigned to receive study intervention according to the assigned treatment group from the randomization scheme. Investigators will remain blinded to each participant's assigned study intervention throughout the course of the study. In the event of a Quality Assurance audit, the auditor(s) will be allowed access to unblinded study intervention records at the site(s) to verify that randomization/dispensing has been done accurately. Sponsor staff not directly involved in the conduct of the study will be unblinded to participants' assigned study intervention.

Primary Purpose:

Treatment
