15 Clinical Trials for Various Conditions
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.
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.
This is a study to test the hypothesis that time to healing of a cold sore will be lower in the active treatment arm of the study when compared to the vehicle (placebo). Subjects with a history of cold sores will be enrolled and administered active treatment or placebo in a blinded manner. Subjects will then be followed to assess time to healing.

Demonstrate the safety and efficacy of NB-001 in subjects with recurrent herpes labialis (RHL).
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.
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
Purpose of this study is to determine the safety and efficacy of topical applications of NB-001 as compared to placebo for the treatment of recurrent herpes labialis.
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.
Researchers are looking for a better way to treat people who have recurrent herpes labialis, also known as cold sores. This is a type of viral infection that causes redness and blisters on the mouth and lip and that recurs. Herpes labialis is caused by a virus called the herpes simplex virus (HSV). The infection is spread when a person comes into direct contact with someone else who has the infection. Once a person becomes infected with HSV, the virus multiplies and spreads, which can cause redness and blistering on the mouth and lip. The blisters crust over and heal. Once healed, the virus is said to go into an "inactive" phase. This means the virus does not cause any symptoms, but still remains in the body. HSV can then become "active" again. This means causing cold sore lesions to reappear. HSV can become active in different ways. Some of these include when a person has a fever, comes into contact with strong sunlight or has a condition that lowers one's immune system It can also happen during a woman's menstrual cycle, also called a period. In this study, the researchers want to gather additional data on acyclovir 50 mg tablet, an available treatment for herpes labialis. It is a buccal tablet that sticks to the gum inside the mouth and directly treats the infected area to help stop the HSV from multiplying and spreading. In this study, the researchers want to compare the efficacy of acyclovir 50 mg buccal tablets versus placebo in the treatment of herpes labialis. A placebo is a treatment that looks like the study medicine but does not have any medicine in it. Study participants will include those who have had at least 4 episodes of herpes labialis within the past 12 months prior to joining the study. To compare the study treatments, the researchers will measure the "duration of episode" (DOE) for each participant. DOE is amount of time it takes for symptoms to disappear and for herpes labialis lesions to heal after taking the study treatment. A doctor will look at the participants' symptom scores and facial images to determine the DOE. Assessments will be done over a period of 14 days. The participants in this study will apply either acyclovir 50mg buccal tablet or the placebo as a tablet to the upper gum 1 time. There will be a 2 week treatment phase and a 12 month follow up phase. The participants in this study will not be required to visit the study site. Instead, the participants will have virtual meetings with the study doctors from their homes using the internet. During the treatment phase, there will be 2 meetings. Throughout the follow up phase, the doctors will call the participants 4 times. Each participant will be in the study for about 20 months. During the treatment phase of the study, the participants will: * take their blood pressure and pulse * check their mouth health through a questionnaire * take pictures of their face and herpes labialis symptoms During the whole study the participants will answer questions about how they are feeling, what medications they are taking, and what adverse events they are having. The doctors will keep track of any adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
The purpose of this study is to determine if Merlin, a mixture of ethanol and glycolic acid, is safe and effective in the treatment of cold sores. Subjects who meet the requirements to participate in the study will be put randomly, and equally, into one of two groups: 1) a group receiving Merlin to treat their cold sore; or 2)a group receiving a placebo of just ethanol to treat their cold sore. Neither the subject nor the site will know which treatment they will be getting. Once the subject has been assigned to a treatment group, they will be given a kit containing a bottle of the treatment and special swabs to apply the liquid. The subject will be told to take the kit home and wait until they think they are starting to get a cold sore. Once a subject begins to see something that they think is the start of a cold sore, they are to immediately call the clinic. Once the clinic confirms that the subject is in fact starting to get a cold sore, the subject will be told to open the kit and begin treatment. From the start of treatment, there will be twelve (12) treatments, with either Merlin or placebo, applied six (6) hours apart, up to 3 per day, over the next 96 hours (4 days). Each treatment of Merlin or placebo is made up of three (3) applications given twenty (20) minutes apart, for a total of thirty-six (36) applications. For each application, the subject will use the special swab to put the Merlin or placebo solution on their cold sore. Subjects will need to report daily to the clinic for a minimum of 3 consecutive days, until either the cold sore is completely healed or 14 days from the start of treatment, whichever comes first. At each clinic visit the cold sore will be observed to determine at what stage it is at or if it has healed. The subject will also be asked how they are feeling. Subjects will also be told to record in a diary the time of each application of Merlin or placebo. They will also be asked to record the stage of their lesion and how much pain, if any, related to the cold sore, that they are feeling.
