Active clinical trials for "Herpes Genitalis"

The objective of the study is to determine the efficacy and safety of 0.5% and 2% PRO 2000/5 gels compared to placebo in preventing vaginally acquired HIV infection.

Genital herpes (HSV-2) is the most common cause of genital sores worldwide, and the presence of genital sores is a significant risk factor for becoming infected with HIV. This study will test the effectiveness of twice-daily dosing of acyclovir, a commonly prescribed anti-herpes drug, in preventing HIV infection in HSV-2 infected women who sleep with men (WSM) and men who sleep with men (MSM). Study hypothesis: Given that genital herpes is a significant risk factor to HIV acquisition, twice-daily HSV-2 suppressive therapy - 400 mg of acyclovir - will prevent HIV infection among high risk, HSV-2 seropositive WSM and MSM.

The objective of this study is to evaluate the safety and tolerability of single rising doses of ASP2151 under fasted condition in healthy male subjects. The study will also evaluate the pharmacokinetics (PK) of a single dose of ASP2151 under fasted versus fed conditions in healthy male subjects.

The purpose of this study is to see if valacyclovir (Valtrex) is a safe and effective treatment for ano-genital HSV infections (herpes simplex virus infections of the anus and external genitals) in HIV-infected patients.

Herpes virus type 2 (HSV-2) infection - as a cofactor of human immunodeficiency virus (HIV) transmission - can be targeted by anti-herpetic specific drugs, either as a continuous prophylactic treatment during its asymptomatic shedding phase, or as an episodic treatment during clinically-apparent genital ulcerations. The main objective of this trial will be to demonstrate that acyclovir treatment given during clinical episodes (primary infection or recurrences) can reduce genital shedding of HIV, thereby contributing to a reduction of HIV infectiousness of dually infected individuals (HIV+/HSV+).

To determine the efficacy of Famvir 500mg bd as suppressive antiviral therapy for acute genital Herpes simplex virus (HSV) outbreaks in HIV subjects.

This study is a follow-up study from Study GEN-003-002 to evaluate long-term efficacy and immunogenicity of GEN-003 in subjects with genital HSV-2 infection.

The purpose of this study is to collect and assess information on proper use of valaciclovir regarding safety and efficacy of long-term use in suppressive therapy for subjects with recurrent genital herpes.

Brief summary: The current management guidelines recommended by ACOG rely on history as a screening method to determine pregnant women who are at risk for transmitting herpes to their newborn. History fails completely in identifying the women most at risk of transmitting herpes to their newborn - the seronegative woman who acquires a primary infection from her partner during pregnancy. Despite recent advances, both pregnant women and newborns continue to be at risk of acquiring herpes infection. Genital herpes infections are epidemic in the United States. In the early 1990's, 25% of women in the US were seropositive for the HSV-2 antibody. These numbers are likely higher now. The incidence of neonatal herpes in the US cannot be accurately estimated since it is not a reportable disease. However, in some areas of the US, the incidence is 1 in 3,200 live births which would translate to an incidence of approximately three infants a day in the US . In other areas of the US, the incidence is even higher, approaching 1 in 1,500 liveborns. This protocol examines patient acceptance of HSV-1 and HSV-2 type specific serologic testing and assesses patient counseling tools. In addition, seroprevalence of HSV-2 in pregnant patients will be collected and evaluated.

Preterm delivery (PTD), together with low birthweight (LBW), is the leading cause of infant death and illness, affecting 500,000 births with annual medical costs of more than $26 billion in the U.S. each year. Identifying changeable risk factors to reduce PTD is considered a top research priority. Recent research has shown genital herpes infection (HSV) is associated with increased risks of PTD and LBW. More importantly, treating this infection, including infection with no symptoms, using readily available antiviral medications can be effective in removing the risk due to HSV. Thus, early identification and treatment of HSV in pregnant women could be an effective way to prevent PTD and LBW. Currently, many pregnant women with HSV infection, especially those with no symptoms, choose not to treat due to (a) a lack of demonstrated benefit of treatment and (b) general hesitance to use medications during pregnancy due to safety concerns for the fetus. Thus, emerging evidence of an increased risk of PTD/LBW associated with HSV infection, if untreated, and treatment effectiveness by anti-herpes medications has significantly changed current treatment paradigms among pregnant women. This evidence also provides new hope that effectively treating HSV infection among pregnant women, especially before the 3rd trimester, could lead to a new method to reduce PTD and LBW and reduce racial/ethnic disparities in these risks due to high rates of the infection in minority groups. To further examine the effectiveness of treating HSV in pregnant women to reduce adverse pregnancy outcomes, the investigators propose to conduct a prospective cohort study with a two-stage design combining the large pregnant women population (N=90,000) in Stage I identified through Kaiser Permanente Northern California (KPNC) electronic medical records (EMRs), with a Stage II sample to collect detailed information on additional factors that might muddle our understanding of this issue. This study will address the following: (1) Does treating HSV infection in pregnant women reduce the risk of PTD or LBW? (2) Does timing of the treatment during pregnancy influence treatment effectiveness? (3) Do other factors influence treatment effectiveness? and (4) Does HSV infection in pregnancy, if untreated, increase the risk of PTD and LBW, compared to no infection? Answers to these questions will be valuable to pregnant women and clinicians, and directly address their concerns when making treatment decisions
