Clinical Trial Summary

Healthy male and female volunteers will be given SQ109 300mg daily for 14 days to assess the safety and tolerability and pharmacokinetics.

Description:

This is a Phase 1C randomized, placebo controlled, double-blinded, in-patient trial of a single oral dose of 300 mg of SQ109 given daily for 14 consecutive days to evaluate the safety, tolerability and pharmacokinetics of SQ109 in normal healthy male and female subjects 18-45 years of age.

Each subject will receive 300 mg of SQ109 or placebo.

• Subject has a positive blood screen for HIV, hepatitis B surface antigen (HBsAg), or hepatitis C antibody and/or a positive history for alcohol abuse or dependence and/or a positive serum ethanol or a positive urine screen for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine metabolites, marijuana, opiates, phencyclidine (PCP)).

• Subject has a baseline QTcF interval >450 msec (males) or >470 msec (females) (defined in Section 9.1.3) or a family history of prolonged QTcF syndrome or premature cardiac death.

• Subject has Wolf Parkinson White Syndrome (WPW) or family history of WPW or a history of supra-ventricular tachycardias or syncope.

• Subject has lived with a person having active TB or has traveled to an area of endemic TB within the past 12 months.

• Subject has an abnormal result on the Ishihara color test, the funduscopic exam, current optic neuritis or known retinal disease.

• Subject has an uncontrolled intercurrent illness (i.e., active infection) or fever (oral temperature >/=100 degrees F or >/= 37.7 degrees C).

• Subject has had major surgery within 4 weeks of study entry.

• Women who are pregnant or breastfeeding.

• Subject has donated blood within the past 30 days prior to Day 1 of the study.

• Subject has allergy to ethambutol or related compounds.

• Subject is an employee of or family member of an employee of Sequella, Quintiles, or DynPort Vaccine Company LLC (DVC).
