NCT ID: NCT05806918

Last Updated: 2023-04-10

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE3
• Total Enrollment: 368 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-04-01

Brief Summary

The goal of this clinical trail is to demonstrate the non-inferiority of recombinant human interferon α-2b gel (ZK-A03) after changing the manufacturer of the active ingredient in patients with herpes zoster.

This double-blind study will enroll approximately 368 adult patients with herpes zoster in China. Eligible patients will be assigned randomly at a 1:1 ratio.

For each patient who is included, treatment may last up to 10 days. During the study, subjects will be treated with recombinant human interferon α-2b gel (either before or after the alteration of the active ingredient manufacturer), at a frequency of four times a day, together with a background therapy of valaciclovir hydrochloride.
