23 Clinical Trials for Various Conditions
The aim of the study is to find out whether AIC316 is safe and efficacious for the prevention of reactivation of genital herpes
The investigators propose a randomized, double blind, placebo-controlled, cross-over trial to evaluate the effect of oral and topical (vaginal gel) tenofovir on genital herpes simplex virus (HSV) shedding among herpes simplex virus type-2 (HSV-2) seropositive, human immunodeficiency virus (HIV) seronegative women. The investigators hypothesize that tenofovir will reduce genital HSV shedding compared to placebo.
This study is designed to compare the performance of the NOWDx HSV-2 Test to a currently marketed device. The intent is to show the rapid test device is comparable to the currently marketed device. The NOWDx HSV-2 Test is intended for qualitatively detecting the presence or absence of human Immunoglobulin G (IgG) class antibodies to HSV-2 in human whole blood to aid in the diagnosis of infection caused by herpes simplex virus type 2 (HSV-2).
The purpose of this trial is to evaluate the safety and efficacy of a therapeutic DNA vaccine in adults with symptomatic herpes simplex virus type 2 (i.e., genital herpes).
The purposes of this study are: * To determine the accuracy of commercially available serologic assays in diagnosing patients with herpes simplex virus type 2 (HSV-2); * To assess the sensitivity and specificity of the commerical assays using HSV-2 western blot as the "gold standard" in a diverse patient population; * To develop testing strategies and recommendations for screening asymptomatic populations for HSV-2.
This trial is to determine the safety of valacyclovir in persons with chronic hepatitis C and herpes simplex type 2 infection. Participants will be randomized to valacyclovir or matching placebo. After receiving the initial therapy for eight weeks, the participants will cross over to the alternate therapy for an additional eight weeks. Each treatment period will be separated by a two-week period of daily placebo. The hypothesis is that treatment with valacyclovir will result in a significant reduction in serum levels of hepatitis C virus ribonucleic acid.
This investigation assessed the effects of asymptomatic BV on daily genital tract shedding of HSV-2 by determining shedding frequency before and after treatment of asymptomatic BV.
This exploratory trial will have three parts. Part A is a dose escalation part, Part B is an expanded safety and dose evaluation part, and Part C is a safety and immunogenicity evaluation part in individuals with recurrent HSV-2 genital herpes. Part A will focus on the safety evaluations, and in addition, vaccine-induced immune responses (specifically neutralizing antibodies) will also be analyzed to assess if there is a dose-response. Part B of the trial will expand the safety characterization for two dose levels of BNT163 selected based on Part A data and will also enable a more comprehensive assessment of the impact of pre-existing immunity to HSV-1 and -2 on the safety and immune responses to BNT163. Part C will evaluate safety and immunogenicity of BNT163 compared to a placebo in a three-dose regimen in subjects with a history of HSV-2 recurrent genital herpes.
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.
This study evaluates the reduction in viral shedding after vaccination with a new formulation of GEN-003 in subjects with genital HSV-2 infection. Two-thirds of the participants will receive GEN-003, one-third will receive placebo.
This is a voluntary study to allow subjects who received placebo while on GEN-003-002 to be randomized, in a blinded manner, to 1 of 6 active combinations of GEN-003 and Matrix-M2. Objectives: * To compare the impact on clinical Herpes Simplex Virus type-2 (HSV-2) disease among 6 different combinations of GEN-003 antigens and Matrix-M2 adjuvant measured by: * Time to first clinical and/or virologic recurrence after Dose 3 (Day 43) * Proportion of subjects who are recurrence free at 6 and 12 months after the last dose of vaccine * Lesion rate (percent of days with genital lesions present) during the post-vaccination follow-up period * Antiviral use. * To evaluate the safety and tolerability of GEN-003 in combination with Matrix-M2.
This is a randomized, double-blind, factorial study to compare the reduction in viral shedding among 6 different combinations of GEN-003, a therapeutic HSV-2 vaccine and Matrix-M2 adjuvant. Secondary objectives of the study include: * Evaluation of the safety and tolerability of GEN-003 in combination with Matrix-M2 compared to placebo. * Comparison of the impact on clinical Herpes Simplex Virus type-2 (HSV-2) disease among the 6 different combinations of GEN-003 antigens and Matrix-M2 adjuvant measured by: * Time to first clinical and/or virologic recurrence, * Proportion of subjects who are recurrence free at 6 and 12 months after the last dose of vaccine, * Lesion rate (percent of days with genital lesions present) during the post-vaccination swabbing periods. * Evaluation of cellular and humoral responses to GEN-003 antigens. Additional objectives include: * Assessment of the correlation between immune responses and change in viral shedding or impact on clinical disease as defined above. * Determination of the recurrence rate in a subset of subjects not receiving suppressive antivirals throughout the study. Eligible subjects will enter a baseline period to collect anogenital swabs for 28 consecutive days prior to randomization. Each subject will receive up to 3 doses at 21 day intervals. Subjects will be followed for safety and immunologic response for 12 months following their last dose.
The purpose of this study is to test the safety and effectiveness of two experimental therapeutic vaccines against herpes simplex virus, type 2 (HSV-2).
The purpose of this study is to evaluate the effect of recombinant human heat shock protein 70-polyvalent peptide complex (HerpV) vaccine administration on recurring episodes of genital herpes by evaluating viral shedding before and after treatment.
Randomized, double-blind, placebo-controlled, dose escalation study. There will be 3 cohorts of patients defined by the antigen dose (10, 30 or 100 µg of each antigen), and within each cohort, patients will be randomized at a ratio of 3:1:1 to one of the following: 1. GEN-003/M2: GEN-003 plus Matrix M-2 adjuvant (50 µg per dose) 2. GEN-003: Antigens alone 3. Placebo (DPBS diluent) Each Cohort is divided into 2 Groups. For each dose cohort, immunizations begin with a Pilot Group. Immunization of the remainder of the Group "Continuation Group") is contingent upon successful review of data from the Pilot Group through Day 7 after immunization. Dose escalation to the next dose level Cohort proceeds after evaluation of safety data from all patients in the prior Cohort and only after all specified safety criteria are met. The total numbers of patients in each Group and Cohort are as follows: * 10 µg Cohort: 10 Pilot Group, 40 Continuation Group (50 Total) * 30 µg Cohort: 10 Pilot Group, 40 Continuation Group (50 Total) * 100 µg Cohort: 10 Pilot Group, 40 Continuation Group (50 Total) * Totals per group: 30 Pilot Group, 120 Continuation Group (150 Total Patients) Subjects will receive 3 doses of the assigned treatment (GEN-003/M-2, GEN-003, or placebo) at 3 week intervals. Sampling from mucocutaneous genital sites for viral shedding will be done twice daily for 28 days prior to the first immunization (baseline shedding), and again following the last immunization. Follow-up for safety monitoring will be conducted for 12 months after the last immunization.
We will be examining the effects of suppressive valacyclovir therapy on the stability of vaginal flora in women who are seropositive for HSV-2. We have preliminary data that suggests the presence of HSV-2 increases the risk for Group B Streptococcus colonization as well as many other deleterious organisms (e.g. Streptococcus pseudoporcinus), in addition to increasing the risk for acquisition of BV-associated vaginal flora. We will be examining the effects of suppressive therapy on the vaginal flora of any HSV-2 seropositive woman.
The purpose of this study is to generate safety and immunogenicity data and establish a proof-of-concept of clinical benefit of the mRNA-1608 vaccine candidate.
The aim of this study is to find out if the process of HIV replication in the lymph tissue and gut tissue of people taking HIV drugs causes long-term damage to the ability of the gut to protect you from other infections and health problems.
The purpose of this study is to study the effects of valacyclovir on patients who have hepatitis C and antibodies to herpes simplex type-2. Herpes simplex type 2 is a virus which causes genital herpes. Some persons with genital herpes have sores in their private areas but most persons do not have any symptoms at all. Valacyclovir is a medication which is commonly used to treat or prevent outbreaks of genital herpes. This medication is already approved by the Food and Drug Administration to treat genital herpes. Valacyclovir has not been approved to treat chronic hepatitis C. The study will take 16 weeks. Participants will be assigned to take either the study drug, valacyclovir, or a sugar pill that looks exactly like valacyclovir. The researchers and the persons participating will not know which medication they are receiving. Study visits will occur every two weeks and will take approximately 3-45 minutes. All study visits will occur at the G.V. Sonny Montgomery VA Medical Center.
To compare the effect of high-dose valacyclovir (1 gram orally twice daily) versus standard-dose acyclovir (400 mg orally twice daily) on the frequency of genital HSV reactivation and on plasma HIV-1 levels among HSV-2/HIV-1 co-infected individuals. The investigators hypothesize that high-dose valacyclovir will result in greater reduction in plasma HIV-1 and genital HSV reactivation.
The purpose of this study is to evaluate how well the vaccine is tolerated at sites where administrations are given and any effects it may have on subjects' wellbeing. The study will also test the ability of vaccine to cause particular immune responses in the body and evaluate the effect it has on herpes outbreaks
The purpose of this study is to determine the rates of sexually transmitted infections (STI) among a group of African American women who have sex with women (AA WSW). The first study hypothesis is that AA WSW are at risk for acquiring and transmitting STI, including the human immunodeficiency virus (HIV). The second study hypothesis is that AA WSW participate in multiple high-risk sexual activities that may facilitate transmission of STIs, including HIV.
The purpose of the study is to determine how common herpes is among persons with HIV who do not know they have it and if valacyclovir reduces outbreaks of herpes, the amount of HIV in the blood, and the amount of HSV in bodily secretions.
