Safety and Pharmacokinetics of UV-4B Solution Administered Orally as Multiple Ascending Doses to Healthy Subjects

Phase 1TerminatedNCT02696291

Emergent BioSolutions7 enrolled

Overview

The purpose of this study is to evaluate the safety and pharmacokinetics of UV-4B oral solution when administered to healthy subjects three times a day (TID) for 7 days.

This is a phase 1, randomized, double-blind, placebo-controlled multiple-ascending dose study to evaluate the safety and pharmacokinetics of UV-4B oral solution when administered to healthy subjects TID for 7 days. Three cohorts of 8 subjects each (6 active, 2 placebo) are planned and up to 2 additional cohorts may be added pending safety review of the initial cohorts. Safety review will occur after each cohort. Safety is evaluated through Day 15 on the basis of adverse event (AE) monitoring, clinical laboratory testing (hematology, serum chemistry, coagulation, urinalysis), vital signs, physical examinations (PE), electrocardiograms (ECG), and fecal occult blood testing. Blood samples are collected at specified intervals up to Day 10 for pharmacokinetic assessment.

Inclusion Criteria: * Nonsmoking, healthy male or female subject aged 18 to 45 years, inclusive. * Female subject is not pregnant and not lactating. * (Female subjects only who are not postmenopausal or sterile) agreement to use hormonal contraception OR intrauterine device PLUS barrier contraception (condom or occlusive cap such as a diaphragm or surgical vault cap) AND spermicidal foam/gel/cream/suppository starting at least 14 days before the first dose and continuing for at least 3 months after the last dose. * (Male subjects only) agreement to use barrier contraception during sexual intercourse and to also refrain from sperm donation from the first day of dosing until 3 months after the last dose of the study product. * Body weight within 60 to 90 kg, inclusive, and body mass index between 18 to 32 kg/m², inclusive. * Agreement to avoid strenuous exercise starting 4 days before the start of dosing through the period of confinement in the clinical unit and for at least 96 hours before the follow-up visits. Exclusion Criteria: * History of allergy to drugs in the iminosugar class. * Treatment with any investigational products or therapies within 30 days (or 5 half-lives, whichever is greater) before the first day of dosing. * Current or past history of disease/dysfunction of the pulmonary, cardiovascular, endocrine, hematologic, neurological, immune, gastrointestinal genitourinary, or other body system. * Abnormalities on physical examination suggestive of conditions that may pose an increased risk to the subject; abnormal electrocardiogram results (excluding benign conditions); and Grade 1 or higher abnormalities in vital signs at screening and Grade 2 or higher abnormalities in vital signs at check-in based on a modified version of the FDA Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials. * Clinical laboratory tests outside the normal range at screening and Grade 2 or higher at check-in to the clinical unit. * Creatinine clearance \< 90 mL/min (based on Cockcroft-Gault equation). * Proteinuria greater than or equal to 1+. * Any known or expected risk of bleeding. * Scheduled surgical procedure during study participation. * History of alcohol and/or drug abuse within 1 year prior to dosing and/or a positive urine drug screen for substances of abuse at screening or check-in. Urine alcohol above 50 mg/dL. * Plasma or blood donation within 30 days before the first day of dosing or intention to donate within 30 days after the final day of dosing. * Treatment with any medication, either prescription or nonprescription, including dietary supplements or herbal medications, within 14 days before dosing (within 30 days before dosing for hepatic or renal clearance-altering agents) and is unable to refrain from any medication during the study period. Exceptions are acetaminophen (not more than 2 g/day), vitamin products at recommended daily doses or hormonal birth control. * Positive serology test for HIV antibodies, hepatitis B surface antigen, or hepatitis C virus antibody at screening. * History of relevant food allergies (ie, eggs or other components of standard clinic meals) or unwilling to comply with diet restrictions. * Psychological and/or emotional problems which would render the informed consent invalid, or limit the ability of the subject to comply with the study requirements; * Concurrent enrollment in any other clinical trial within 30 days.

Outcomes

Primary Outcomes

Number of Subjects Reporting Treatment-emergent Adverse Events (TEAEs) by Group

The incidence of TEAEs spontaneously reported by subjects or elicited during examination is reported by dose group. Subjects having multiple TEAEs are counted only once.

Time frame: From the time of first dosing on Day 1 through the Day 15 final follow-up visit

Number of Subjects Reporting Serious Adverse Events (SAEs) by Group

The incidence of SAEs spontaneously reported by subjects or elicited during examination is reported by dose group. Subjects having multiple SAEs are counted only once.

Time frame: From the time of first dosing on Day 1 through the Day 15 final follow-up visit

Number of Subjects With Clinical Laboratory Abnormalities of Toxicity Grade 1 or Higher by Group

Clinical laboratory abnormalities are presented as the total of Grade 1 (mild) through Grade 4 (potentially life-threatening) abnormalities according to criteria adapted from the Food and Drug Administration (FDA) Guidance for Industry, Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (September 2007) and the Division of Microbiology and Infectious Diseases (DMID) Adult Toxicity Table (November 2007). Within each parameter, subjects having multiple abnormalities are counted only once.

Time frame: From the time of first dosing on Day 1 through the Day 15 final follow-up visit

Secondary Outcomes

Number of Subjects With Outlying Vital Sign Results by Group

Vital signs of blood pressure (BP), pulse, respiratory rate, and oral temperature were taken after being supine for 10 minutes. Orthostatic vital signs (BP, pulse) were taken after 2 minutes standing. Vital sign results are presented as the number of subjects having Grade 1 (mild) through Grade 4 (potentially life-threatening) abnormalities according to criteria adapted from the FDA Guidance for Industry, Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (September 2007), or having abnormal orthostatic change (standing minus supine result). Within each parameter, subjects having multiple abnormalities are counted only once.
