Dose Escalation Study of SQ109 in Healthy Adult Volunteers

November 3, 2011 updated by: National Institute of Allergy and Infectious Diseases (NIAID)

A Phase 1B, Randomized, Placebo-Controlled, Double-Blinded, Dose-Escalation Study to Evaluate Safety, Tolerability and Pharmacokinetics of Single-Daily Doses of SQ109 in Normal, Healthy Male and Female Volunteers

The purposes of this study are to determine: how safe it is to take SQ109 (an experimental tuberculosis treatment) once a day by mouth for up to 2 weeks in 2 different dosages; how well the body accepts it; how SQ109 enters and leaves the body and blood tissues over time; the amounts that can be detected in the blood; and how long it stays in the body. The study involves 30 volunteers: 24 will receive SQ109 and 6 will receive placebo (inactive substance). Qualified participants will be admitted to the study unit within 28 days from the screening and stay as inpatient for approximately 2 weeks. During this period they will receive study drug and complete all scheduled procedures including multiple blood draws. After discharge, there is a 14 day follow up period. Total study participation is about 56 days.

Detailed Description

Tuberculosis (TB) is one of the most important global health problems. According to recent estimates from the World Health Organization, 8 million new cases of TB and 1.9 million deaths from TB occur annually, making TB the second leading cause of death from an infectious pathogen. Due to multidrug resistant TB, the need for new and more effective drugs to treat TB is well recognized. This study is a phase 1B, prospective, single-center, double-blinded, randomized, placebo-controlled, clinical study of SQ109 to evaluate single-daily dose tolerability and pharmacokinetics (PK) of oral SQ109 in healthy subjects. The objectives of the study are to: determine the safety and tolerability of SQ109 administered daily for 14 days in healthy male and female volunteers; assess single dose and multiple dose PK of SQ109 administered daily for 14 days in healthy male and female volunteers; and assess single dose and multiple dose PK of SQ109 administered twice per week after a 5-day loading regimen in healthy, male and female volunteers. A total of 30 subjects, ages 18-45, will be enrolled in the study, allocated equally among 3 cohorts of 10 subjects each, 8 treated with active drug and 2 with placebo. Subjects in Cohorts 1 and 3 will receive an oral dose of 75 mg or 150 mg, respectively, of study medication daily for 14 days. Subjects in Cohort 2 will receive 150 mg daily for 5 days followed by 2 additional doses of 150 mg on Days 9 and 14. Subject participation will include a screening visit within 28 days of study entry, a 14 day in-patient treatment period, and a 14 day out-patient follow-up phase. Safety will be assessed by study personnel continually during the 14 day in-patient treatment period and the out-patient follow-up phase. Adverse events will be recorded for all subjects. Other safety measures include laboratory tests, electrocardiograms (ECGs), visual and neurological assessments, physical examinations, and vital signs. Study duration will be approximately 6 months. Subject participation duration will be 56 days.

Eligibility Criteria

Eligibility Criteria

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.

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
