Active clinical trials for "Herpes Simplex"

Genital herpes (GH) is a commonly occurring sexually transmitted disease caused by herpes simplex virus (HSV). There are two types of HSV, type 1 (HSV-1) and type 2 (HSV-2); both can cause GH, although the latter is much more likely to produce frequent recurrences of GH lesions. Evidence suggests that there are advantages to using suppressive vs. episodic treatment, which include increased intervals between the pain and discomfort of genital herpes recurrences. Therefore, this study will collect safety and efficacy data on suppressive therapy with valaciclovir in subjects newly diagnosed with HSV-2 genital herpes.

The study is designed to assess the efficacy and safety of famciclovir 250 mg twice a day (bid) suppressive treatment in men and women with herpes virus type 2 (HSV-2) infection, with and without a reported history of genital herpes and with or without herpes virus type 1 (HSV-1) seropositivity.

The purpose of this study is to test whether long-term treatment with oral acyclovir improves the outcome for infants with herpes simplex virus (HSV) disease of the skin, eyes, and mouth (SEM). Study participants will include infants in the United States and Canada who have HSV disease of the skin, eyes, and mouth, with no central nervous system disease present. Initially, all subjects will be treated with acyclovir administered through IV access (through the vein) for 14 days while hospitalized. Participants will then be placed in one of two groups, acyclovir given by mouth or a placebo (substance with no medication present). The participant and the study site will not know to which group the subject is assigned. All children will be followed at 6, 12, 24, 36, 48, and 60 months of age. During the follow up visits, physicals, hearing assessments, eye assessments, and neurological assessments will be completed.

To evaluate the safety of topically applied SP-303 gel and to compare the efficacy of SP-303 gel in combination with acyclovir, relative to acyclovir alone, for the treatment of recurrent Herpes Simplex Virus (HSV) 1 and 2 infections, affecting the genital, perianal and neighboring areas, in patients with AIDS.

This study will evaluate the effectiveness of the drug valaciclovir in preventing transmission of genital herpes from an infected to an uninfected sexual partner. Genital herpes is caused by the herpes simplex virus 2 (HSV-2), or, infrequently herpes simplex virus 1 (HSV-1). Valaciclovir prevents the herpes virus from multiplying and may also reduce its transmission between partners. Couples 18 years of age and older in which one partner is infected with HSV-2 (source partner) and the other is not (susceptible partner), may be eligible for this study. Candidates will be screened with blood tests for routine laboratory studies and to verify the presence or absence of HSV-2 or HSV-1 infection. Participants will give a medical history, undergo a physical examination, including genital examination, and receive counseling on safer sex practices and how to recognize signs and symptoms of a possible first episode of genital herpes. Source partners will also be counseled on transmission of genital herpes, and susceptible partners will be interviewed about their sexual history and practices. The source partner will be randomly assigned to take either a 500-mg tablet of valaciclovir or placebo (a pill with no active ingredient) daily for 8 months. All participants will be given diary cards to complete for a month-the source partner will record any drug side effects and the susceptible partner will record any signs or symptoms of possible HSV infection. Participants will be seen in the clinic once a month for 8 months. At these visits, source partners will 1) return unused study medication and the completed diary card; 2) discuss any adverse drug side effects experienced in the last month; 3) review medications other than the study drug taken in the last month; 4) undergo counseling on safer sex practices, transmission of genital herpes, and recognizing signs and symptoms of a first episode of genital herpes; and 5) review symptoms and recurrences of genital herpes experienced during the last month. During the final visit, they will also provide a blood sample for routine testing and possible use in future studies. Susceptible partners will 1) have a blood sample drawn for HSV testing; 2) undergo safer sex counseling; 3) review any symptoms experienced over the last month; 4) be interviewed about sexual exposure and practices; and 5) return the completed diary card. Source partners who have a recurrence of genital HSV while on the study will be asked to have their lesions cultured and will be offered open-label valaciclovir treatment. Susceptible partners who contract genital herpes from the source partner during the study will have a genital examination to verify a fist episode of genital herpes and will receive 10 days of open-label treatment with valaciclovir. Cultures will be taken from the mouth and genitals, current medical conditions will be reviewed, blood samples will be drawn on treatment days 1 and 10, and treatment side effects will be reviewed on days 5 and 10. At the end of the study, infected partners will be offered a 12-month course of valaciclovir, one 500-mg tablet daily. Participants will be followed in the clinic once every 3 months to provide blood samples, return unused study medication and the diary card, discuss any drug side effects, review medications taken besides the study drug, and review symptoms or recurrences of genital herpes. All participants will be asked to complete a questionnaire for gathering information about people with genital herpes and people at risk for the infection.

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.

The purpose of this study is to see if valacyclovir affects the detection of HIV in genital herpes lesions in HIV-infected patients. Valacyclovir is used to treat recurrent genital herpes.

The aim of this study is to assess performance of using healthcare tools to understand genital Herpes Simplex Virus-2 (HSV-2) in patients ≥ 18 years of age in the United States and Europe. More specifically, the study aims to evaluate patient-reported outcome and quality-of-life endpoints as well as the performance study procedures in a decentralised setting. Ultimately, this study will allow generating additional real-world evidence (RWE) on patterns of recurrences and other key parameters.

The objective of this study was to prove the bioequivalence of Valacyclovir Hydrochlorothiazide Caplet under fed conditions.
