Filter by:The purpose of this first-time-in-human (FTiH) study is to assess the reactogenicity, safety and immunogenicity of four different dose levels of an experimental herpes simplex virus type 2 (HSV-2) vaccine, when administered intramuscularly (IM) on a 0, 2-month schedule to healthy participants aged 18-40 years.
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.
Herpes simplex virus (HSV) infection is very common, as most people will experience herpetic infection during their lifetime. The most common manifestation of HSV infection is sores which may appear at any age. No specific antiviral therapy is available to totally cure herpetic infections and today, there is no treatment that allows the definitive eradication of the virus. The 2LHERP® has been available for more than 20 years, and has received a marketing authorization in Belgium by the FAMHP. It is used as an immune regulator in the treatment of herpetic infections. Since 2LHERP® has been made available, clinical observational data collected on treated patients have shown the beneficial effect on the disappearance of herpetic recurrences. The purpose of this placebo-controlled trial is to evaluate the efficacy of 2LHERP® on the treatment of herpetic infections in adults.
The primary objectives of the study are: - To describe the safety profile of different investigational vaccine regimens against herpes simplex virus type 2 (HSV-2). - To evaluate the efficacy of the investigational vaccine regimens with respect to: - the frequency of herpes simplex virus (HSV) deoxyribonucleic acid (DNA) detection in the genital area (shedding rate) following a 2 dose vaccine schedule - the proportion of participants free of HSV genital recurrence at 6 months after the 2-dose vaccine schedule The secondary objectives of the study are: - To describe the impact of each of the investigational vaccine regimens in terms of total number of days with genital lesion up to 6 months after vaccination 2 and number of recurrences 60 days after the second vaccination compared with the placebo group - To describe the efficacy of each of the investigational vaccine regimens with respect to the frequency of HSV DNA detection in the genital area (shedding rate) 60 days following the first vaccination visit plus 60 days following the second vaccination visit compared with the placebo group - To describe the efficacy of each of the investigational vaccine regimens with respect to the frequency of HSV DNA detection in the genital area (shedding rate) 60 days following the first vaccination visit compared with the placebo group
Valacyclovir has replaced acyclovir in many clinical scenarios. Pharmacokinetic data support the use of oral valacyclovir in children, but practical problems exist in children having to take adult-dose tablets. A formulation with acceptable palatability, good pharmaceutical quality and possibility of flexible dosing is developed. Pharmacokinetic data of this formulation is missing. The present study investigates the pharmacokinetics of valacyclovir oral solution in children by determine the area under the curve (AUC0-12), time above critical concentration (Ccrit), Cmax and Tmax of acyclovir. Secondary, the safety profile of a single dose of valacyclovir oral solution will be determined.
The purpose of this study is to compare a corneal sampling realized by a flocked swab (flocked swab regular 519CS01) with a sampling by traditional fiber swab (Copan regular swab 164KS01 in polyester). Their impact on the sensibility of the viral culture in the Herpes simplex epithelial keratitis will be the primary objective of this study.
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.
The objective of the study is to evaluate the acceptance and effect of type- specific HSV serologic testing of pregnant women on sexual behavior at the end of pregnancy.
The purpose of this study to look at the antibodies (proteins from the body's infection fighting system) in the blood of babies delivered by women who are participants in the Herpevac Trial for Women, and who were vaccinated with either two or three doses of (GlaxoSmithKline) GSK candidate vaccine gD2t/alum-MPL or hepatitis A vaccine. The goal of this study is to compare the herpes or hepatitis A antibody levels of the newborns to those of their mothers, and to see how much of the antibodies are still present in the baby at two and six months after birth. Approximately 2 teaspoons (10 ml) of the mother's blood will be collected at the time of delivery or within 15 days before or after delivery. Approximately 2 teaspoons of blood will be collected from the child's umbilical cord at the time of delivery, or 1 teaspoon (3-5 ml) of the child's blood will be drawn within 15 days after birth. Optional blood draws from babies may occur 2 and 6 months after birth.
