Safety and Efficacy Comparator Trial of a New Drug Against Genital Herpes

Phase 2
Terminated
Conditions
Genital Herpes
Interventions
Registration Number
NCT01658826
Lead Sponsor
AiCuris Anti-infective Cures AG
Brief Summary

The aim of the study is to evaluate the safety and efficacy of "AIC316 (pritelivir)" 100 mg once daily compared to valacyclovir 500 mg once daily for the prevention of HSV-2 genital shedding.

Detailed Description

Enrolled patients with Mucocutaneous genital HSV, will be randomized to receive either AIC326 or Valacyclovir first and then will be crossed over to receive the opposite Intervention. The study will consist of two treatment periods of 28 days separated by a washout period of 28 days.

Primary Outcome Measures
NameTimeMethod
Within-subject Genital HSV Mucocutaneous Shedding Rate28 days

Subjects were assessed for within-subject genital HSV mucocutaneous shedding rate, as calculated by the number of HSV-positive swabs per subject relative to the total number of swabs collected per subject. The swab test detects the presence of herpes virus DNA. A swab was regarded as positive for HSV-DNA if at least 3 HSV genome copies were detected by quantitative PCR per reaction (equaling 150 copies per mL of swab collection medium). When multiple swabs were available from the same time point (e.g., genital and lesional swab), the swab with the highest copy number was retained for computation of the shedding rate.

Overall Shedding Rate28 days

Subjects were assessed for overall shedding rate as the total number of HSV-positive swabs per treatment group divided by the number of swabs collected per treatment group.
