Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Concurrent Medication:
  • Allowed:
  • Dapsone at a constant dose level and only as a prophylaxis for Pneumocystis carinii pneumonia (PCP).
  • Zidovudine (AZT) at a constant dose for the 12 weeks of treatment, except if AZT-related toxicity is observed.
  • Patients must have the following:
  • HIV seropositive (asymptomatic, AIDS-related complex, or AIDS).
  • HIV-associated immune thrombocytopenic purpura.
  • The ability to sign a written informed consent form, which must be obtained prior to treatment.
  • A willingness to abstain from all other experimental therapy for HIV infection during the entire study period.
  • Patients currently on zidovudine are not excluded. However, the zidovudine dose level must remain constant for 4 weeks prior to entry and for the 12 weeks of treatment, except if zidovudine related toxicity is observed.
  • A life expectancy of at least 3 months.
  • Prior Medication:
  • Allowed:
  • Dapsone at a constant dose for more than 2 weeks prior to study entry.
  • Zidovudine at a constant dose for 4 weeks prior to study entry.

You may not qualify if:

  • Co-existing Condition:
  • Patients with the following conditions and symptoms are excluded:
  • Active serious opportunistic infection (excluding positive block cultures of Mycobacterium avium complex or Cytomegalovirus).
  • Malignancies other than Kaposi's sarcoma.
  • Tumor-associated edema.
  • Visceral Kaposi's sarcoma.
  • Significant neurologic, cardiac, or liver disease.
  • Concurrent Medication:
  • Excluded:
  • Ganciclovir (DHPG). Pyrimethamine. Clindamycin. Sulfadiazine. Folinic acid. Prednisone. Intravenous gamma globulin. Intravenous acyclovir. Interferon. Systemic corticosteroids. Non-steroidal anti-inflammatory drugs (NSAIDs). Known immunomodulatory agents. Dideoxycytosine. Dideoxyinosine. Nucleoside analogs (with the exception of zidovudine or topical acyclovir). Any experimental therapy.
  • Patients with the following are excluded:
  • Active serious opportunistic infection (excluding positive block cultures of Mycobacterium avium complex or Cytomegalovirus).
  • Malignancies other than Kaposi's sarcoma.
  • Kaposi's sarcoma requiring therapy.
  • Tumor-associated edema.
