Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with acute herpes zoster who can give informed consent, agree to required contraception measures, and meet safety criteria (no allergies or contraindicated medications) are appropriate candidates.

Probably not a fit

Patients with known allergy to brivudine, famciclovir, or penciclovir, those currently using fluorouracil agents, or others with contraindications to the study drugs are unlikely to benefit from participation.

What this trial studies

This randomized, multicenter trial enrolls 140 adults with herpes zoster at five centers in China and compares brivudine (125 mg/day) with famciclovir (dose adjusted for kidney function) for seven days. Participants are followed at Days 3, 7, 14, 30, and 90 to measure pain (Numeric Pain Rating Scale), time to lesion healing, postherpetic neuralgia incidence, and adverse events. The primary endpoint is pain score on Day 30, with secondary endpoints including earlier pain scores, lesion resolution time, PHN rate, and safety. Results will show whether one antiviral provides faster pain relief or lowers the risk of postherpetic neuralgia.

Why it matters

Potential benefit: If successful, the better-performing antiviral could provide faster pain relief and reduce the risk of postherpetic neuralgia for adults with shingles.

How similar studies have gone: Antiviral therapy for acute herpes zoster is well established and drugs like famciclovir have shown effectiveness, but direct head-to-head data comparing brivudine and famciclovir are limited.
