Summary

Study Design

Investigational study involving a total of 33 participants that examined the effect of co-administration of telaprevir and etravirine.

Study Results

Etravirine lowered telaprevir minimum concentration (Cmin) by 25%, maximum concentration (Cmax) by 10%, and 8-hour area under the concentration-time curve (AUC) by 16%. None of these modest changes were considered clinically relevant. Telaprevir had no impact on concentrations of etravirine: least square mean (LSM) ratios and 90% confidence intervals for etravirine concentrations with versus without telaprevir were all within 80% to 125%.

Study Conclusions

Interaction seen between telaprevir and etravirine was deemed to not be clinically significant.
