A Study to Compare Sitavig (Acyclovir) Buccal Tablet With a Placebo in the Treatment of Herpes Labialis...

Recurrent Herpes Labialis

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.

Viral Infections in Healthy and Immunocompromised Hosts

Anogenital HerpesCOVID-191 more

Background: - Viral infections are an important cause of illness and death in hospitalized patients as well as outpatients. New strains of viruses may appear and infect both healthy people and those with weak immune systems. A better understanding of these new virus strains (such as SARS-CoV-2, the virus that causes COVID-19) may help to control and prevent these infections. In particular, some viral infections that are less problematic in healthy persons can be life threatening in persons with weak immune systems, and viruses may be able to evolve more rapidly in persons with weak immune systems and therefore develop resistance to existing treatments. Researchers are interested in collecting samples and information from otherwise healthy persons or persons with weak immune systems to study the effects of viruses and their development. Objectives: - To collect samples and data from individuals who have been exposed to or have contracted viral infections. Eligibility: Individuals of all ages who have been diagnosed with a viral infection are suspected to have a viral infection, or have been in close contact with someone with a suspected or actual viral infection that is of interest to investigators in the Laboratory of Infectious Diseases. Healthy persons and persons with weak immune systems (immunocompromised individuals) are eligible to participate. Design: Participants will be pre-screened to determine if they meet the eligibility criteria for the trial. If eligible, evaluation may include a medical chart review, a history and physical examination, review of clinical reports from outside hospitals and laboratories, and review of tissue biopsies. Study procedures may include collection of blood, urine, saliva, nasal fluid sampling, throat swabs, stool, and genital swabs. For participants who have specimens collected as part of their medical care (e.g. wound swabs, spinal tap, bronchoscopy, liver biopsy etc.), researchers may use leftover specimens from the clinical laboratory for testing. Specimens may be collected up to 4 times per week during the first 2 weeks after enrollment, and then as many as 2 times per week for up to 2 years. Some participants may be asked to continue providing specimens if there is concern for relapse or recurrence of the infection. Treatment is not offered under this study.

Monoclonal Antibody Therapy Against Chronic Herpes Simplex Virus 1 Infection

Herpes Labialis

This is a phase II, double-blind, randomised, controlled, multicentre trial of topical HDIT101 versus placebo. HSV-1-positive patients with at least 6 orolabial herpes lesions in the last 12 months can be included. The patients need to present with 3 herpes lesions within a 9 months observation phase. With the occurrence of the third lesion, the patients will enter the 12 months treatment phase and will be randomized in a 2:1 ratio to topical HDIT or placebo applied over 2 days. A potential fourth lesion will also be treated with the blinded study medication and additional lesions will be documented. In a 12 months post-trial follow-up phase, further information on the occurence of lesions will be collected 4 times by phone. Study duration per patient will be up to 21 months plus 12 months post-trial follow-up by phone. Patients need to come for study visits up to 9 times.

Immune Response to the Consumption of Lactobacillus GG and FOS in Patients With Recurrent Herpes...

Herpes Labialis

Background: Herpes labialis is the result of the presence of Herplex Simplex Virus -1 (HSV-1) and is a common disease in the population. Because of its visibility it has a serious impact on social life and the feeling of well-being in people who suffer from this disease. Until now there is no effective treatment and no remedy for prevention of the virus outbreak. 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 far no study has addressed the effect of the consumption of pre- and/or probiotics in a population with recurrent herpes labialis. Aim of the study: The present study investigated the effect of pre- or probiotics or a combination of the two on the recurrence of herpes labialis lesions as well as on the immune system in general. Design: 78 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 four experimental groups, these were: placebo minidrink (n=), prebiotic (fructooligosaccharides) minidrink (n=), probiotic (Lactobacillus rhamnosus GG or LGG) minidrink (n=) or a minidrink containing a combination of a pre- and probiotic. These minidrinks were consumed for another 5 weeks. At day 33 of the study the lip most prone to the development of a lesion was stimulated with UVB in order 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 quality of life questionnaire at baseline (day 14) and the end of the study (day 49). In addition, a blood sample was collected at baseline and at the end of the study to be analyzed for general and HSV-specific antibodies, intracellular cytokine concentrations and parameters of the innate immune response such as natural killer cell activity and phagocytosis.

A Double-Blind, Randomized, Placebo-Controlled Study of Topical VDO for the Treatment of Herpes...

Herpes Labialis

Recurrent herpes labialis are usually a minor malady of limited duration, although they are often painful and are uniformly discomforting for patients. Oral antivirals represent an advance in the treatment of recurrent herpes labialis, but the clinical implications are modest. Randomized, controlled clinical trials have shown that oral antivirals decrease the duration of lesion episodes and pain by approximately one day. In recurrent HSV infections including herpes labialis, many instances of viral re-activation occur without symptoms, and can only be identified by detection of virus on the lips of infected individuals. In these cases, the virus is cleared from the local site without the development of a classical ulcerative herpes lesion. In the other cases, the triggered specific immune response rapidly stops viral replication in the skin and also causes the development of the herpes lesion prodrome and a considerable part of the symptoms associated with a classical ulcerative herpes lesion. One could therefore predict that treatment with an antiviral drug alone would help the immune system in shortening the virus replication, but may not substantially reduce the disfiguring symptoms caused by the immune reaction. In dermatology, the principle of using an anti-inflammatory drug improve clinical outcomes by reducing inflammation-related symptoms associated with the infection has been well established. We have found that a topical formulation of VDO is useful for alleviating pain and inflammation associated with infection caused by herpes virus.

Study of a Cold Sore Patch for the Treatment of Herpes Labialis

Herpes Labialis

If a person qualifies to participate in this study, they will have an equal chance of being assigned to either of two groups. One group will receive a patch that they will need to carry with them, because as soon as a cold sore starts (within 1 hour) they will need to put the patch over the sore. The other group will not get a patch, but will need to follow the other instructions anyway. When a subject's outbreak begins, they will need to return to the study center within 24 hours. Then they will return according to the appointments given within 10 days. If the study staff sees that their sore has healed enough before 10 days, subjects will be told that they don't need to return again. As long as subjects are in the study, they will need to answer a few simple questions every day on a card or booklet called a diary, starting the first day of their outbreak. If a subject is assigned to the patch group, they must wear the patch all the time, taking it off only to replace it (if it gets loose, dirty, or unsightly) and at the study center, when they are asked to remove the patch so the sore can be checked. During the study subjects will be allowed to use paracetamol for pain, but no other treatments or medicine. If they use paracetamol, subjects must record it in their diary. The study will be stopped, and there will be no subject visits or treatments during the end of year holiday break. If a subject experiences an outbreak during the holiday, they may follow their usual treatment routine.
