A Study To Evaluate The Safety And Effects On The Body Of An Investigational Drug Using An Endotoxin-Induced Inflammatory Response Model (POM)

June 21, 2016 updated by: Pfizer

A Phase 1, Randomized, Double Blind, Placebo Controlled, Multiple Dose, 2 Way Crossover Study To Evaluate The Safety And Pharmacodynamic Effects Of Pf 06282999 Using An Endotoxin (Lipopolysaccharide) Induced Inflammatory Response Model In Healthy Adult Subjects

An endotoxin challenge will be administered to healthy subjects to induce production of inflammatory markers. An investigational drug or placebo will be administered prior to the endotoxin challenge to assess the effect of the investigational drug on the markers of inflammation. Safety and tolerability will also be assessed.

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
Measure Description
Time Frame
Peak Myeloperoxidase (MPO) Activity Following Inflammatory Stimulus
Time Frame: Days 1, 3-5
MPO is a heme-containing peroxidase enzyme produced in the bone marrow and stored in the azurophilic granules of neutrophils, where it constitutes up to 5% of the cellular protein. Since PF-06282999 is a mechanism-based inactivator of MPO, it is of interest to evaluate the level of MPO activity in order to investigate the inhibition activity of PF-06282999.
Days 1, 3-5
MPO Activity (Area Under the Concentration-time Profile From 0.5 to 2 Hours [AUC0.5-2hrs]) Following Inflammatory Stimulus
Time Frame: Days 1, 3-5
MPO is a heme-containing peroxidase enzyme produced in the bone marrow and stored in the azurophilic granules of neutrophils, where it constitutes up to 5% of the cellular protein. Since PF-06282999 is a mechanism-based inactivator of MPO, it is of interest to evaluate the level of MPO activity in order to investigate the inhibition activity of PF-06282999.
Days 1, 3-5
MPO Activity (Area Under the Concentration-time Profile From 0 to 2 Hours [AUC0-2hrs]) Following Inflammatory Stimulus
Time Frame: Days 1, 3-5
MPO is a heme-containing peroxidase enzyme produced in the bone marrow and stored in the azurophilic granules of neutrophils, where it constitutes up to 5% of the cellular protein. Since PF-06282999 is a mechanism-based inactivator of MPO, it is of interest to evaluate the level of MPO activity in order to investigate the inhibition activity of PF-06282999.
Days 1, 3-5
Number of Participants With Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and Withdrawals Due to TEAEs
Time Frame: From Day 0 till approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2 (up to approximately 2 months)
An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs comprised both SAEs and non-SAEs. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were defined as newly occurring AEs or those worsening after first dose. Due to early termination of the study, only AE data from partial enrollment are reflected and comparisons between treatment arms should not be attempted.
From Day 0 till approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2 (up to approximately 2 months)
Number of Participants With Laboratory Test Abnormalities
Time Frame: Baseline up to 7-10 days following the last dose of PF-06282999/Placebo in Period 2
Number of participants with laboratory test abnormalities without regard to baseline abnormality. Laboratory test parameters included hematology, coagulation, liver function, renal function, electrolytes, clinical chemistry, and urinalysis (dipstick and microscopy). Due to early termination of the study, only laboratory data from partial enrollment are reflected and comparisons between treatment arms should not be attempted.
Baseline up to 7-10 days following the last dose of PF-06282999/Placebo in Period 2
Number of Participants With Change From Baseline and Absolute Values in Vital Signs Meeting Categorical Summarization Criteria
Time Frame: Screening and Days 1-2, 4-5, and approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2 for orthostatic (orth) measurements; Day 3 for supine measurements
Categorical summarization criteria in vital signs included: sitting, supine, and standing systolic blood pressure (SBP) of less than (<)90 millimeters of mercury (mm Hg) or change (increase [inc] or decrease [dec]) in sitting, supine and standing SBP of more than or equal to (>=)30 mm Hg; supine, sitting, and standing diastolic blood pressure (DBP) of <50 mm Hg or change (inc or dec) in sitting, supine, and standing DBP of >=20 mm Hg; supine and sitting pulse rate (PR) of <40 or more than (>)120 beats per minute (bpm); and standing PR of <40 or >140 bpm. Due to early termination of the study, only vital signs data from partial enrollment are reflected and comparisons between treatment arms should not be attempted.
Screening and Days 1-2, 4-5, and approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2 for orthostatic (orth) measurements; Day 3 for supine measurements
Number of Participants With Electrocardiogram (ECG) Values Meeting Categorical Summarization Criteria
Time Frame: Screening; Days 1-5 and approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2
Criteria for ECG (12-lead) values meeting categorical summarization criteria were: the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization (PR interval >=300 milliseconds (msec) and increase from baseline >=25/50%; time from the beginning of the ECG Q wave to the end of the S wave corresponding to ventricular depolarization (QRS) interval >=140 msec and increase of >=50%; the beginning of the Q wave to the end of the T wave corresponding to electrical systole (QT) interval >=500 msec; QT corrected using the Fridericia formula (QTcF) of 450 to <480 msec, 480 to <500 msec, and >=500 msec, or an increase of 30 to <60 msec or >=60 msec. Due to early termination of the study, only ECG data from partial enrollment are reflected and comparisons between treatment arms should not be attempted.
Screening; Days 1-5 and approximately 7-10 days following the last dose of PF-06282999/Placebo in Period 2
Number of Participants With Abnormal Urinary Biomarker Values
Time Frame: Days 1-3 prior to dosing with PF-06282999/Placebo; and Days 4-5
Urinary biomarkers included albumin, neutrophil gelatinase-associated lipocalin (NGAL) and Cystatin-C.
Days 1-3 prior to dosing with PF-06282999/Placebo; and Days 4-5

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
Concentrations of TNF-alpha, IL-1 Beta, IL-6, IL-8, and hsCRP
Time Frame: Days 1, 3, and 4
The effect of multiple oral doses of PF-06282999 on inflammatory biomarkers was a secondary objective in this study. The biomarkers are tumor necrosis factor (TNF)-alpha, interleukin (IL)-1 beta, IL-6, IL-8, and high-sensitivity C-reactive protein (hsCRP).
Days 1, 3, and 4
Peak (AUC0.5-2hours and AUC0-2hours) of MPO Activity/MPO Mass
Time Frame: Days 1, 3-5
MPO is a heme-containing peroxidase enzyme produced in the bone marrow and stored in the azurophilic granules of neutrophils, where it constitutes up to 5% of the cellular protein. Since PF-06282999 is a mechanism-based inactivator of MPO, it is of interest to evaluate the level of MPO activity in order to investigate the inhibition activity of PF-06282999.
