Active clinical trials for "Herpes Simplex"

To investigate the efficacy and safety of three different doses of ASP2151, as compared to valacyclovir hydrochloride in subjects with herpes zoster, and to determine the recommended clinical dose.

The purpose of this study is to determine whether acyclovir is effective in suppressing HIV viral load in women infected with both HIV-1 and herpes simplex virus type 2 (HSV-2) who are starting HIV treatment for the first time.

The purpose of this study is to determine if acyclovir episodic treatment has an effect in ulcer healing and if it should be added to the syndromic management of genital ulcer disease.

This study will evaluate the safety and blood levels of a new pediatric formulation of Famvir in children 1-12 years of age. In Part A, patients will receive a single dose of famciclovir (12.5 mg/kg) to assess pharmacokinetics (PK) and safety. In Part B, patients will receive multiple doses of famciclovir alone or with concomitant oral anti-herpes therapy to assess safety and tolerability. Part B will start only after PK data from Part A had been analyzed.

The study is designed to assess the efficacy and safety of patient-initiated therapy with famciclovir 1500 mg o.d. or 750 mg b.i.d. for one day treatment in adult men and women with recurrent herpes labialis

OBJECTIVES: I. Determine the efficacy of long term suppressive therapy with oral acyclovir in infants with herpes simplex virus infection limited to skin, eyes, and mouth. II. Determine the neurologic outcome in these patients when treated with this regimen. III. Evaluate the significance of a positive cerebrospinal fluid (CSF) polymerase chain reaction (PCR) result when all other CSF parameters remain normal in these patients. IV. Correlate the time to first positive CSF PCR result in the first 12 months of life with clinical neurological assessment in these patients when treated with this regimen. V. Determine whether the continuous administration of this drug suppresses recurrent skin lesions in these patients. VI. Determine the safety of this regimen in these patients.

To evaluate the safety and efficacy of oral valacyclovir hydrochloride (256U87) vs. acyclovir in the treatment of recurrent anogenital herpes in HIV-infected patients (CD4 greater than or equal to 100).

PRIMARY: To evaluate the clinical activity of foscarnet cream on the index lesion of mucocutaneous herpes simplex virus (HSV) infections in immunocompromised patients previously unresponsive to acyclovir treatment. SECONDARY: To evaluate the clinical activity and virologic activity of foscarnet cream on all treated lesions in this patient population. To evaluate the local tolerance and side effects of treatment with foscarnet cream in this patient population.

Part A: To evaluate the impact of HSV suppression with acyclovir ( ACV ) on HIV burden in patients with asymptomatic HSV infection and at high risk for HSV reactivation. Part B: To characterize the change in plasma HIV RNA levels and other measures of HIV burden during and after a 10 day course of ACV treatment for acute HSV infection. Approximately 70% of patients infected with HIV are concurrently infected with HSV. There is new evidence to suggest that HSV may act as a co-factor in HIV disease progression. This study will attempt to determine if the upregulation of HIV RNA that occurs during symptomatic HSV reactivation also occurs during asymptomatic HSV reactivation and if suppression of HSV will result in decreased levels of HIV RNA. There is a need to determine the patterns of association between HSV and HIV.

To determine the safety, effectiveness, and toxicity of topical (local) trifluridine in treating mucocutaneous (at the nasal, oral, vaginal, and anal openings) Herpes simplex virus ( HSV ) disease that has shown resistance to acyclovir in HIV-infected patients. HSV infection in patients with AIDS is often associated with skin sores and frequent recurrences. Treatment with the drug acyclovir results in healing for most patients, but repeated treatment sometimes results in resistance of the virus to acyclovir. Thus, when this happens, other treatments need to be used. Trifluridine is an antiviral drug that is used for the treatment of Herpes infections that occur in the eye. This study attempts to determine if trifluridine is useful for treating HSV sores that have not healed after treatment with acyclovir.
