Study summary

The purpose of the study is to compare how the body takes up and then eliminates the study drug BCX4161 when it is taken orally as a hard gelatin capsule and as a soft gelatin capsule. This study will also evaluate whether food has any effect on how the body takes up BCX4161.

What researchers measure

Primary outcomes

  1. Plasma pharmacokinetics to assess the relative bioavailability of BCX4161 soft gelatin capsules to hard gelatin capsules

    Time frame: Pharmacokinetic parameters AUC0-inf, AUC0-t and Cmax generated after 24 hours of postdose blood sampling

Secondary outcomes

  1. Safety and tolerability evaluated through assessments of adverse events, laboratory analyses, vital signs, ECGs, and physical examinations

    Time frame: Screening through study completion (approximately 61 days)

  2. Plasma pharmacokinetics to assess the effect of food on BCX4161

    Time frame: Pharmacokinetic parameters AUC0-inf, AUC0-t and Cmax generated after 24 hours of postdose blood sampling
