Overview

To compare the safety and effectiveness of fluconazole and amphotericin B as maintenance treatment for preventing the relapse of cryptococcal meningitis in patients with AIDS.

Study Type

  • Study Type: Interventional
  • Study Design
    • Primary Purpose: Treatment

Interventions

  • Drug: Fluconazole
  • Drug: Amphotericin B

Participating in This Clinical Trial

Inclusion Criteria

Concurrent Medication:

Allowed:

  • Antivirals such as zidovudine.
  • Prophylaxis (including aerosolized pentamidine) for Pneumocystis carinii pneumonia (PCP).
  • Pfizer must be notified if the patient is receiving ganciclovir (DHPG) at entry.

Concurrent Treatment:

Allowed:

  • Radiation therapy for mucocutaneous Kaposi's sarcoma.

Patients must be oriented to person, place, and time, and able to give written informed consent.

  • Patients must have had an acute episode of cryptococcal meningitis that was documented by recovery and identification of Cryptococcus neoformans from lumbar cerebrospinal fluid (CSF) culture within 6 months prior to entry.
  • Minimum total dose of 15 mg/kg of amphotericin B must have been given (either alone or in combination with flucytosine) during primary therapy.
  • Patients need not be receiving amphotericin B at the time of randomization but must begin study maintenance therapy within 6 weeks of completion of primary amphotericin B therapy. Patients may receive maintenance amphotericin B during the period between completion of primary therapy and study entry.
