A Study To Asses Mass Balance And Absolute Bioavailability Of 14C PF-06826647 In Healthy Male Participants

February 17, 2021 updated by: Pfizer

A PHASE 1, OPEN LABEL, 2-PERIOD, FIXED SEQUENCE, STUDY TO ASSESS THE MASS BALANCE, ABSOLUTE BIOAVAILABILITY OF 14C PF 06826647 IN HEALTHY MALE PARTICIPANTS

The purpose of the study is to determine the metabolism and excretion following a single oral administration of 14C-PF-06826647-LR (14C labelled PF-06826647 with lower radioactivity per mass unit) in fed conditions. This information will enable assessment of clearance mechanisms of PF-06826647 as well as identify metabolites. In addition, this study will determine absolute bioavailability of PF-06826647 and understand intravenous (IV) pharmacokinetic (PK).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Total radioactivity in urine and feces together expressed as percent of total oral radioactive dose
Time Frame: Up to Day 14
Up to Day 14

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Laboratory Test Values of Potential Clinical Importance
Time Frame: Up to Day 28
Pre-defined criteria were established for each laboratory test to define the values that would be identified as of potential clinical importance.
Up to Day 28
Number of participants with abnormal ECG
Time Frame: Up to Day 28
Criteria for ECG abnormalities: maximum PR interval >=300 milliseconds (msec) and maximum increase PR interval increase from baseline (IFB): percent change (Pctchg) >=25 percent (%) for baseline value of >200 msec and Pctchg>=50% for baseline value of <=200 msec for PR interval, maximum QRS interval >=140 msec and a maximum IFB: Pctchg>=50%, maximum QTCF interval (Fridericia's Correction) of 450 msec to <480 msec, 480 msec to <500 msec or >=500 msec and a maximum change of <=30change<60 or >=60 msec from baseline.
Up to Day 28

Time Frame: Up to Day 28
Following parameters were analyzed for examination of vital signs: systolic and diastolic blood pressure, respiratory rate, radial pulse and body temperature.
Up to Day 28
The ratio of dose normalized AUCinf of PF-06826647 and 14C-PF-06826647
Time Frame: 0 hours to 96 hours
The ratio of dose normalized AUCinf of PF-06826647 (LCMS) and 14C-PF-06826647 (AMS). AUCinf= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time . It is obtained from AUC (0 - t) plus AUC (t - ∞).
