Active clinical trials for "Herpes Labialis"

The Purpose of this study is to evaluate the safety of ME-609 for the treatment of recurrent herpes labialis in adolescents.

A randomized study comparing the combination of valacyclovir and temovate gel (clobetasol gel) versus placebo for the treatment of recurrent herpes labialis (cold sores).

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 site where the herpes virus is replicating. Iontophoresis uses electric current to enhance the delivery of drugs through the skin. This trial is testing a new iontophoretic device for the delivery of acyclovir cream to treat cold sores.

Eligible subjects will be randomized to receive VALTREX 1g or placebo once daily for 60 days in a two-way crossover study with a washout period of 7 days in between.

This study will treat approximately 24 participants who experience cold sores. Patches will be applied to the cold sore for up to ten days, and the symptoms will be measured during daily clinic visits using non-invasive measurement techniques.

The purpose of this study is to evaluate the episode duration of a herpes labialis recurrence in immunocompromised patients treated with ME-609 or Acyclovir.

This study evaluates the safety and efficacy of SADBE in the prevention of recurrent herpes labialis in adults. Two-thirds of the participants will receive a SADBE solution, while the other third will receive only the vehicle as a placebo control. The solutions will be administered topically to the patient's arms. The study will compare a single-arm application versus a two-arm application versus two placebo doses on the arm.

Comparison of the efficacy of penciclovir 10 mg/g (1%) cream with that of vehicle at 72 hours in preventing the appearance of classical lesions following prodromal symptoms (tingling or burning sensation) based on thermographic assessment among recurrent cold sore sufferers.

About 80% of the worldwide population is positive on HSV antibodies. In the United States the lifetime prevalence of recurrent herpes labialis is estimated at 20% to 40%, with approximately 100 million episodes occurring in the country every year. In Switzerland about 70% of the adult population is positive on HSV-1 and about 20% is positive on HSV-2. The Herpes simplex virus has a lipid bilayer (virus-envelope), which causes the sensitiveness, to any kind of detergents. Within this bilayer cholesterol molecules are integrated and play a crucial role in virus entry into host cells. In vitro experiments have clearly shown that the depletion of cholesterol in HSV-envelope with 2- HPßCD has inhibited the ability of the virus to infect host cells. The aim of this clinical trial is to reduce the number of Herpes labialis relapse and to provide patients with recurrent Herpes labialis a real benefit, concerning the simple mechanism of action and the negligible side effects. Patients having problems in swallowing the antiviral pills of standard treatment, will find with 2- HPßCD a drug, that just has to be applied on the lips, which increases patient's quality of life tremendously. Trial with medicinal product

Subjects were recruited who were positive for antibody against herpes simplex virus type 1 (HSV-1) and self-reported having in the previous 12 months 6 or more herpes labialis outbreaks (group A), 1 or 2 outbreaks (group B), or zero outbreaks (group C). Twelve subjects in each group were recruited. Blood was collected from these persons and peripheral blood mononuclear cells (PBMCs) isolated and tested for proliferation in vitro when stimulated with HSV-1-infected cell extracts, free HSV-1 virus, or Candida albicans extract. Candida albicans is a ubiquitous infectious fungus and its extract is used as a test of general immune response. RNA was also isolated from the PBMCs after incubation in the three stimuli and expression of 41 immune-related genes quantified by quantitative real-time PCR. Also serum anti-HSV-1 IgG levels were quantified. After the blood collection on day 1, the persons in group A (frequent cold sore sufferers) were treated with a single topical application of 2% squaric acid dibutyl ester (SADBE) in DMSO, applied to the inner aspect of the upper arm. These subjects returned on days 15 and 57 for blood collection, and their PBMCs were tested again on those dates for proliferation in vitro against the same stimuli and for gene expression and for serum anti-HSV-1 IgG levels.
