Study Summary

This trial is being done to study the efficacy of acyclovir 50mg buccal tablet in the treatment of recurrent herpes labialis, also known as cold sores. Acyclovir is a medication used to treat viral infections and the tablet form sticks to the inside of the mouth to directly treat the infected area. The study will compare the duration of the episode for those taking acyclovir 50mg buccal tablet to those taking a placebo. There will be 2 weeks of treatment and a 12 month follow up phase with virtual meetings from home using the internet.

Who is the study for?
Adults 18+ with frequent cold sores (at least 4 episodes in the past year) can join this trial. Participants must not disturb their cold sore lesions, be willing to avoid certain medications and treatments that affect immune response, and follow study instructions. Women of childbearing age need effective birth control and a negative pregnancy test.Check my eligibility
What is being tested?
The trial is testing if a buccal tablet containing Acyclovir (50mg), which sticks to the gum inside the mouth, is more effective than a placebo at treating herpes labialis. The main focus is on how quickly symptoms disappear after treatment over a period of up to 20 months with virtual check-ins.See study design
What are the potential side effects?
Possible side effects include allergic reactions for those sensitive to acyclovir or its components, though specific side effects are not listed; all medical problems during the study will be tracked as adverse events.
