NCT ID: NCT00031486 Completed - Encephalitis Clinical Trials

Long Term Treatment of Herpes Simplex Encephalitis (HSE) With Valacyclovir

Start date: September 2000
Phase: Phase 3
Study type: Interventional

This study involves patients 12 years and older who have been diagnosed with herpes simplex encephalitis (HSE) by a specific laboratory test and have completed treatment or are being treated with intravenous (given through a needle inserted into a vein) acyclovir. The purpose of the study is to determine if treatment with 4 tablets, 500 milligrams each, of valacyclovir given 3 times daily by mouth for 90 days is both effective and safe after completing intravenous acyclovir treatment and if it can increase survival with or without mild impairment of the brain and mental functions. Participants will be assigned to either drug or placebo (inactive substance) randomly (by chance). Study procedures will include blood samples and lumbar punctures (procedure in which a needle is inserted into the lower back to collect cerebral spinal fluid). Subjects will participate for up to 24 months.

NCT ID: NCT00031460 Completed - Herpes Simplex Clinical Trials

Acyclovir for Herpes Infections Involving the Central Nervous System in Neonates

Start date: December 1997
Phase: Phase 3
Study type: Interventional

The purpose of this study is to test whether long term treatment with acyclovir given orally (by mouth) improves the outcome for infants with herpes simplex virus infection of the brain or spinal cord (known as the central nervous system [CNS]). Infants with herpes viral infection of the CNS that has or has not spread to other parts of the body will be enrolled in this study. All participants will receive treatment in a hospital for 21 days with acyclovir, given intravenously (by a needle inserted into a vein). Participants will then be divided into two groups: those with CNS disease that has or has not spread to the skin, and those whose viral infection has spread and involves the CNS. Both groups will be randomly assigned to receive either oral acyclovir or placebo (inactive substance) for 6 months. Infants in the US and Canada will participate for 5 years. A physical exam, hearing exam, eye exam, and an evaluation of the nervous system will be performed throughout the study.

NCT ID: NCT00031447 Completed - Herpes Simplex Clinical Trials

Acyclovir Herpes Simplex Virus (HSV) Skin, Eye, and Mouth

Start date: August 1999
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00006135 Completed - Herpes Simplex Clinical Trials

Phase III Randomized Study of Oral Acyclovir in Infants With Herpes Simplex Virus Infection Limited to Skin, Eyes, and Mouth

Start date: June 1997
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00006132 Recruiting - Herpes Simplex Clinical Trials

Phase III Randomized Study of Oral Acyclovir in Infants With Herpes Simplex Virus Infection Involving the Central Nervous System

Start date: June 1997
Phase: Phase 3
Study type: Interventional

OBJECTIVES: I. Determine the efficacy of long term suppressive therapy with oral acyclovir in infants with herpes simplex virus infection involving the central nervous system. II. Determine whether neurologic outcome is improved in these patients when treated with this regimen. III. Determine whether continuous administration of this drug suppresses recurrent skin lesions in these patients. IV. Determine the safety of this regimen in these patients.

NCT ID: NCT00005663 Active, not recruiting - HIV Infections Clinical Trials

A Study of Valacyclovir as Treatment for Genital Herpes Simplex Virus in HIV-Infected Patients

Start date: June 1999
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00004757 Completed - Herpes Simplex Clinical Trials

Phase III Randomized, Placebo-Controlled Study of Acyclovir Oral Suspension for Neonatal Herpes Simplex Virus Infection Limited to the Skin, Eyes, and Mouth

Start date: August 1992
Phase: Phase 3
Study type: Interventional

OBJECTIVES: I. Determine whether acyclovir (ACV) oral suspension suppresses recurrent skin lesions and improves neurologic outcome in neonates with localized herpes simplex virus type 2 infection when administered for 6 months in a placebo-controlled study. II. Determine whether the prevention of recurrent skin lesions reduces long-term neurologic morbidity. III. Determine whether resistant disease develops after oral ACV therapy. IV. Evaluate the natural history of recurrent skin lesions. V. Measure any adverse effects and laboratory abnormalities associated with long-term oral ACV therapy in infants and young children.

NCT ID: NCT00004644 Completed - Herpes Simplex Clinical Trials

Phase I/II Study of High-Dose Acyclovir for Central Nervous System or Disseminated Neonatal Herpes Simplex Virus Infection

Start date: February 1995
Phase: Phase 1/Phase 2
Study type: Interventional

OBJECTIVES: I. Evaluate whether high-dose acyclovir decreases acute and long-term morbidity and mortality in neonates with central nervous system or disseminated herpes simplex virus (HSV) infection. II. Evaluate whether high-dose acyclovir is safe and tolerated in the newborn. III. Assess resistance to antiviral medication. IV. Amplify disease classification for the purpose of predicting prognosis. V. Assess any changes in viral excretion patterns. VI. Evaluate whether antigens and antibodies specific for HSV glycoproteins within the cerebrospinal fluid (CSF) predict long-term neurologic outcome. VII. Evaluate whether specific antigens and antibodies in the CSF appear late after treatment and are indicative of insidious reactivation of virus in the brain.

NCT ID: NCT00002404 Completed - HIV Infections Clinical Trials

The Effect of Valacyclovir on the Detection of HIV From Genital Herpes Lesions in HIV-Infected Patients

Start date: n/a
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00002310 Completed - HIV Infections Clinical Trials

SP-303T Applied to the Skin of Patients With Herpes Simplex Virus (HSV) Infection and AIDS Who Have Not Had Success With Acyclovir

Start date: n/a
Phase: N/A
Study type: Interventional

To evaluate the safety and tolerance of topically applied SP-303T in AIDS patients. To observe the effect of this drug on herpes simplex virus lesions in patients who have failed to heal in response to oral or intravenous acyclovir therapy. The lack of alternative treatments for herpes simplex virus infection in patients with AIDS and the development of resistance to acyclovir for patients requiring repeated treatment presents a therapeutic dilemma for physicians. SP-303T has good in vitro activity against resistant strains and offers a convenient and inexpensive means of drug administration in comparison to the use of intravenous medication.
