A Phase 1, Non-randomized, Open-label, Parallel-group Single-dose Study To Evaluate The Pharmacokinetics, Safety, And Tolerability Of Intravenous Rivipansel (Pf-06460031) In Subjects With Moderate Hepatic Impairment And In Healthy Subjects With Normal Hepatic Function

Area Under the Plasma Concentration-Time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) of Rivipansel

时间窗: Pre-dose, 0.33, 1, 3, 6, 8, 12, 16, 24, 36, 48, 72, and 96 hours post-dose on Day 1

AUCinf was calculated as AUClast + (Clast\*/kel), where Clast\* was the predicted plasma concentration at the last quantifiable time point estimated from the log linear regression analysis, kel was the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

时间窗: Day 1 to follow-up visit (28-31 days after administration of study medication on Day 1)

An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a product or medical device, regardless of its causal relationship with study treatment. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; was life-threatening (immediate risk of death); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs were events between administration of study medication and up to follow-up visit (28-31 days after administration) that were absent before treatment or that worsened after treatment. AEs included both serious and non-serious AEs.

Number of Participants With Vital Signs Data Meeting Pre-defined Summarization Criteria

时间窗: Day 1 to Day 5

Absolute values and changes from baseline (increase and decrease) were summarized for supine diastolic blood pressure (DBP), supine systolic blood pressure (SBP), and supine pulse rate. Number of participants with vital signs findings meeting the following criteria is presented: (1) supine DBP \<50 millimeters of mercury (mm Hg); (2) supine DBP \>90 mm Hg; (3) supine SBP \<90 mm Hg; (4) supine SBP \>140 mm Hg (for normal hepatic function group); (5) supine SBP \>160 mm Hg (for moderate hepatic impairment group); (6) supine pulse rate \< 40 beats per minute (bpm); (7) supine pulse rate \>120 bpm; (8) supine DBP increase from baseline \>=20 mm Hg; (9) supine SBP increase from baseline \>=30 mmHg; (10) supine DBP decrease from baseline \>=20 mm Hg; (11) supine SBP decrease from baseline \>=30 mm Hg.

Total Clearance From Plasma (CL) of Rivipansel

时间窗: Pre-dose, 0.33, 1, 3, 6, 8, 12, 16, 24, 36, 48, 72, and 96 hours post-dose on Day 1

CL of rivipansel was calculated as dose/AUCinf, where AUCinf referred to the area under the plasma concentration-time profile from time 0 extrapolated to the infinite time.

Number of Participants With Post-baseline Clinically Significant Findings in Physical Examinations

时间窗: Day 5

A full physical examination was performed for each participant, and it included head, ears, eyes, nose, mouth, skin, heart and lung examinations, lymph nodes and gastrointestinal, musculoskeletal, and neurological systems. Clinical significance of laboratory findings was determined by the investigator.

Number of Participants With Electrocardiogram (ECG) Data Meeting Pre-defined Summarization Criteria

时间窗: Day 5

Maximum absolute values and increases from baseline were summarized for PR interval (time from the beginning of P wave to the start of QRS complex, corresponding to the end of atrial depolarization and onset of ventricular depolarization), QRS duration (time from Q wave to the end of S wave, corresponding to ventricle depolarization), and QTcF interval (time from the beginning of Q wave to the end of T wave corresponding to electrical systole corrected for heart rate using Fridericia's formula). Number of participants with ECG findings meeting the following criteria is presented: (1) PR interval \>=300 msec; (2) QRS duration \>=200 msec; (3) QTcF interval: 450 to \<480 msec; (4) QTcF interval: 480 to \<500 msec; (5) QTcF interval \>=500 msec; (6) PR interval percent increase from baseline \>=25/50 percent; (7) QRS duration percent increase from baseline \>=50 percent; (8) QTcF interval increase from baseline: 30 to \<60 msec; (9) QTcF interval increase from baseline \>=60 msec.

Number of Participants With Laboratory Test Abnormalities (Without Regard to Baseline Abnormality)

时间窗: Day 5

Laboratory tests included: hematology (hemoglobin, hematocrit, red and white blood cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, platelet count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes, prothrombin time/international normalized ratio), chemistry (blood urea nitrogen/urea and creatinine, fasting glucose, calcium, sodium, potassium, chloride, total carbon dioxide, aspartate and alanine aminotransferase, total bilirubin, alkaline phosphatase, uric acid, albumin, total protein), urinalysis (pH, qualitative glucose, protein, and blood, ketones, nitrites, leukocyte esterase, urobilinogen, urine bilirubin, and microscopy), and other tests (follicle stimulating hormone, urine drug test and serologic tests on human immunodeficiency virus-1 antibody, Hepatitis B surface antigen and hepatitis C antibody). Abnormality was determined by the investigator using widely accepted criteria in clinical practice.
