Active clinical trials for "Herpes Labialis"

The purpose of this study is to determine the efficacy and safety of Botulinum Toxin Type A as a preventative measure for Herpes Labialis.

This study intends to test the efficacy of the TheraNeem Lip Therapy balm for Herpes Simplex. The study will include a total of 5 people.

This study will assess the safety, tolerability of a single 1500 mg dose of famciclovir in 50 adolescents with recurrent herpes labialis. Eight of the 50 adolescents will also participate in the pharmacokinetics (PK) assessment of famciclovir single 1500 mg dose

Currently approved drugs for the treatment of herpes labialis (cold sores) exhibit low levels of efficacy due to the limited ability of the drugs to penetrate the skin to the sites where the herpes virus is replicating. Iontophoresis uses electric current to enhance delivery of drugs through the skin. This trial is testing a new iontophoretic device with a new acyclovir gel to treat cold sores.

The study is designed to assess the efficacy and safety of patient-initiated therapy with famciclovir 1500 mg o.d. or 750 mg b.i.d. for one day treatment in adult men and women with recurrent herpes labialis

Herpes labialis (HL) is the result of the presence of a virus called HSV-1 and is a common disease. Because of its visibility due to cold sores it has a serious impact on social life. Until now there is no effective treatment to prevent virus outbreaks. However, prebiotics and probiotics have both been shown to have a favorable and supportive effect on the immune system in different health conditions such as influenza, atopic dermatitis and diarrhea, so it is possible that they are able to have a favourable effect also on HL. A recently completed pilot clinical trial (Protocol Number 08-SBUS-2-GRA-01, EVIM-1) was completed using a fermented milk (minidrink) containing a combination of L. rhamnosus and FOS; it showed promising results in the reduction of HL recurrences in a population of 78 subjects with HSV-1. The study investigated the effect of pre- or probiotics or a combination of the two on the recurrence of HL lesions as well as on the immune system in general, showing that the consumption of a minidrink containing the probiotic L. rhamnosus or a minidrink containing a combination of L. rhamnosus and FOS reduced the occurrence and the incidence of recurrent HL lesions. Aim of this study: corroborate whether the consumption of a minidrink containing a combination of L. rhamnosus and FOS results in less recurrence and a better progression of HL lesion, in a larger population. In addition, the response of the consumption of the minidrink on the QoL and the response on immunity specific biomarkers were evaluated. Design: 152 patients were eligible to participate in the study and after a run-in period of two weeks consuming a placebo minidrink were randomized to one of the two experimental study groups: placebo minidrink (n=79) and a minidrink containing a combination of a pre- and probiotic (n=78). These minidrinks were consumed until the end of the study (day 140). At day 33 of the study the lip most prone to the development of a lesion was stimulated with UVB to provoke a lesion. During the entire study period subjects were checked for any clinical signs of a lesion, completed a self-assessment regarding the lesion and a QoL questionnaire at baseline (day 14), at day 49 and the end of the study (day 140). In addition, a blood sample was collected at baseline, at day 49 and at the end of the study to be analyzed for HSV-specific antibody concentrations , to check immune system specific functions.

Randomized, double-blind, multi-center, three arm parallel group, comparative trial to assess pritelivir ointment safety and efficacy, ie, proportion of subjects with non-ulcerative lesions, in adult subjects with recurrent herpes labialis (RHL) in comparison with placebo or Zovirax® Cream. The start of treatment with trial medication will be initiated by the subject within one hour of noticing the first sign or symptom (eg, prodrome) of a recurrence of herpes labialis. Trial medication will be applied to the affected area 5 times daily for 4 days. After self-initiation of treatment with trial medication subjects will be assessed daily by the Investigator until complete healing for a maximum of 13 days. Subjects will document application of trial medication and the status of their lesion in a diary. There will also be blood sampling, ECG measurement and physical examination performed at the investigational site.

To compare safety and efficacy of Perrigo's antiviral drug product compared to an FDA approved antiviral drug product in the treatment of cold sores.

To demonstrate the efficacy of a single dose of acyclovir Lauriad® 50mg muco-adhesive buccal tablet versus a single dose of matching placebo on the primary vesicular lesion of cold sore.

Background: A cold sore is usually a blistering rash on or near the lips, caused by infection with herpes simplex virus. After the first infection, the virus goes into a dormant (inactive) state, but it can continue to cause cold sores. Most people with the herpes simplex virus have a few episodes of cold sores per year. However, some individuals may have many recurrent episodes that are uncomfortable and may cause embarrassment. Researchers are attempting to find treatments that can decrease the number of cold sore episodes for people who have six or more episodes per year. Glutamine is a molecule called an amino acid and is one of the components that make up proteins in the body. Clinical studies using glutamine have addressed the potential of glutamine to improve immune function and to heal damaged tissue or to help healing. Objectives: - To find out if the dietary supplement glutamine can help individuals with frequently recurring (more than six episodes per year) cold sores. Eligibility: Patients between 18 and 65 years of age who have a history of having six or more cold sore episodes per year, and have not received certain kinds of drug treatment for the cold sores within 1 month of beginning the study. Patients who have two or more episodes of cold sores caused by the herpes simplex virus will be eligible for treatment as part of this study. Design: Initial clinical visit for a physical examination and medical history, at which blood samples will be drawn for testing. Eligible participants will undergo a 4-month screening period. Patients who develop sores during this period will visit the NIH to have the sore examined to determine if it is caused by the herpes virus. Patients who have two or more episodes of cold sores caused by the herpes simplex virus will be eligible for treatment. Patients who are eligible for treatment will provide an initial blood sample and will receive randomized doses of either glutamine or glycine (another amino acid), which must be taken on a regular schedule twice daily, mixed with either liquid or soft food. Patients who develop sores during this period will visit the NIH to have the sore examined to determine if it is caused by the herpes virus. Blood, urine, and saliva specimens will be collected each month during the treatment period. A 2-week washout period will occur between the 2 treatment periods when no doses of glutamine or glycine will be taken. Patients will then undergo a second 5-month treatment period with either glutamine or glycine (whichever was not given in the first part of the study), taken in the same manner as before. Patients who develop sores during this period will visit the NIH to have the sore examined to determine if it is caused by the herpes virus. After the second treatment, patients will remain in touch with researchers for 1 month to note any changes.
