Evaluation of Brovavir ( BV-ara-U; SQ 32,756 ) Versus Acyclovir in the Treatment of Localized Herpes Zoster in HIV-Infected Patients

HIV-infected patients are at high risk for herpesvirus infections, including
varicella-zoster virus ( VZV ) infections, also called shingles. Acyclovir, an approved
drug, is widely used to treat VZV infections in the HIV population. Since no data from
controlled studies are available to define the role of antiviral therapy for VZV infections
in HIV-infected patients, a study is needed to test the relative efficacy of brovavir, an
experimental antiviral drug, versus that of acyclovir.

One hundred-eighty patients are randomized to receive either brovavir or acyclovir as
follows: brovavir or its matching placebo once daily and acyclovir or its matching placebo
five times daily. Treatment continues for 10 days. Entry into the study must occur within 72
hours of lesion development. Patients are followed in person daily or at regular intervals
during study drug administration and on days 14, 21, and 28, and then monthly by telephone
for 11 months thereafter.

Inclusion Criteria

Inclusion Criteria

Concurrent Medication:


- Medication for concurrent conditions (e.g., insulin, antihypertensives,
bronchodilators, digoxin) or antibacterials or antifungals to treat concurrent
infections at other sites or superinfection of the zoster lesion.

- Anti-inflammatory, analgesic (including narcotic analgesic), or antipyretic agents.

- Antidepressants and antipsychotics such as amitriptyline and/or fluphenazine.

- Nerve blocks.

- AZT, ddI, ddC, and amantadine.

- Low-dose corticosteroids for treatment of an underlying (not zoster-related) disease.

- Immune modulators without varicella-zoster virus activity (e.g., GM-CSF, gp160

Patients must have:

- HIV infection.

- Localized, cutaneous herpes zoster (shingles).

- Zoster-associated rash present for 3 or fewer days prior to entry.

Prior Medication:


- Zidovudine.

- ddI.

- ddC.

Exclusion Criteria

Co-existing Condition:

Patients with the following conditions and symptoms are excluded:

- Chickenpox.

- Evidence of visceral dissemination (organ involvement, i.e., brain, liver, or lung)
and/or cutaneous dissemination (more than 20 vesicles in dermatomes beyond contiguous
dermatomes) of zoster.

- Zoster-like lesion caused by organism other than VZV (e.g., HSV, enterovirus, or

- Bacterial superinfection of zoster lesion.

- Zosteriform lesion previously treated with topical antiviral agents.

- Acute, life-threatening opportunistic infection requiring treatment (ongoing
suppressive or prophylactic maintenance therapy other than ganciclovir or foscarnet
is permitted).

- Concurrent severe disease that may either impair ability to take oral medication in
capsule or tablet form or limit survival during the 10-day treatment period or during
acute phase follow-up (28 days).

- Suspected acute deterioration of renal or hepatic function.

- Mental impairment that precludes ability to comply with protocol.

- Any condition that would render the patient unsuitable for treatment.

Concurrent Medication:

Excluded during acute phase of study:

- Antiviral medications other than AZT, ddI, ddC, or anti-Parkinson's drugs (i.e.,

- Interferon.

- Isoprinosine.

- Levamisole.

- Transfer factor.

- Topical virucidal agents, oxidizing agents, DMSO, cell division-stimulating/healing
agents, or astringents.

- Topical anesthetics (such as capsaicin or xylocaine).

- Topical creams or ointments that may interfere with evaluation of zoster lesions.

- Cimetidine.

- Fluorouracil or its derivatives, flucytosine, or cyclophosphamide (during drug
administration and for 2 weeks thereafter).

- High-dose corticosteroids.

- Anticoagulant therapy (heparin locks and low-dose warfarin sodium permitted).

- Probenecid or derivatives.

- Treatment for any acute, life-threatening opportunistic infection (suppressive or
prophylactic maintenance therapy other than ganciclovir or foscarnet is permitted).

Use of the following drugs is discouraged during the long-term phase of the study:

- Antiviral agents with VZV activity.

- Immunomodulators with presumed VZV activity.

- VZV immune globulin.

- Capsaicin.

- Cimetidine.

Patients with the following prior conditions are excluded:

- History of immediate hypersensitivity or serum sickness reaction or idiosyncratic
reaction (such as hepatic necrosis or Stevens-Johnson syndrome) to any nucleoside
analog antiviral agent or to any anticancer therapy with cytolytic agents.

Prior Medication:

Excluded within 1 month prior to entry:

- Any investigational drugs or treatments not licensed for any indication (other than
ddI or ddC).

Excluded within 2 weeks prior to entry:

- Any systemic antiviral therapy, including ganciclovir, foscarnet, vidarabine,
acyclovir, or ribavirin.

- Any antiretroviral drug other than zidovudine, ddI, and ddC.

- Immune globulin (e.g., IgG, VZIG).

Excluded within 72 hours prior to entry:

- Cyclophosphamide.

- Flucytosine.

- Fluorouracil or its derivatives.

Alcohol or drug abuse.
