Accepts Healthy Volunteers:   No

Inclusion Criteria

Concurrent Medication:


  • Patients may receive oral acyclovir and may continue prophylactic treatment for PCP, fungal infection, MAC and toxoplasmosis.
  • Topical treatment and intralesional chemotherapy will be allowed for lesions which will not be used as indicator or biopsy lesions.

Concurrent Treatment:


Localized radiotherapy will be allowed for lesions which will not be used as indicator or biopsy lesions.

Patients must have:

  • Documentation of a positive ELISA test for HIV with a confirmatory test.
  • Biopsy proven, cutaneous or oropharyngeal Kaposi's sarcoma.
  • Vital signs, physical examination and laboratory assessments that exhibit no evidence of an acute illness.
  • Patients must agree to report all current medications to the primary investigator and obtain prior permission to use them when feasible.

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms and conditions are excluded:

  • Evidence of pulmonary Kaposi's sarcoma.
  • Positive urine screen for recreational drugs.
  • Current participation in another antiviral research study.
  • Investigator anticipates poor patient compliance with the protocol.
  • Patient has any condition that, in the investigator's opinion, may obscure the proper observation of the safety or activity of ritonavir.

Concurrent Medication:


  • Antiretroviral therapy.
  • Protease inhibitor therapy.
  • Antiviral agent (e.g., oral ganciclovir or Foscarnet) or prophylactic medication for an AIDS defining illness which the patient cannot be removed from.
  • Chemotherapy for Kaposi's sarcoma.
  • Treatment with any medications that may interact with ritonavir.

Concurrent Treatment:


Radiotherapy for Kaposi's sarcoma.

Patients with any of the following prior conditions are excluded:

  • History of psychiatric illness which is currently medically significant.
  • History of pancreatitis.

Prior Medication:


  • All antiretroviral therapy within 2 weeks prior to the start of the treatment phase of the study.
  • Systemic chemotherapy of interferon within 30 days prior to study entry.
  • Previous treatment with a protease inhibitor.

Risk Behavior:


Active substance abuse.
