Inclusion Criteria

Concurrent Medication:


  • AZT.

Patients must have:

  • HIV-1 seropositivity.
  • CD4 count <= 300 cells/mm3.
  • No active or acute (onset within the past month) opportunistic infections such as active cryptococcosis, pneumocystis carinii, herpes zoster, histoplasmosis, or cytomegalovirus (CMV).
  • Consent of parent or guardian if less than 18 years of age.
  • Understanding of potential risk to fetus related to study participation.
  • Acceptable medical history, physical exam, EKG, and chest x-ray during screening.


  • Patients with cutaneous Kaposi's sarcoma requiring no systemic therapy are permitted.

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

  • Active tuberculosis that is sensitive to rifampin.
  • Inability to swallow numerous tablets.
  • Clinically significant active or acute medical problems, including progressive multifocal leukoencephalopathy, lymphoma, or malignancy requiring systemic therapy.
  • Clinically significant hypersensitivity to piperazine-type drugs (e.g., Antepar and Stelazine).
  • Grade 2 or worse baseline organ function. NOTE:
  • Hemophiliacs with grade 2 bilirubin, alkaline phosphatase, SGOT, or SGPT will be considered if these values have been stable over the past year. NOTE:
  • Patients with suspected Gilbert's syndrome will be considered if bilirubin is grade 2 or better.

Patients with the following prior conditions are excluded:

  • History of pancreatitis within the past 2 years.
  • History of clinically significant nervous system or muscle disease, seizure disorder, AIDS dementia, or psychiatric disorder that would preclude study compliance.
  • History of grade 2 or worse peripheral neuropathy.
  • Intolerance to ddI in previous treated patients.

Prior Medication:


  • More than 4 months total of prior ddI.
  • Any prior ddC, d4T, or 3TC.
  • Prior nonnucleoside reverse transcriptase inhibitors, including L-drugs, nevirapine, TIBO, HEPT, delavirdine, atevirdine, and alpha-APA.
  • Other investigational antiretroviral medications (including foscarnet) or immunomodulators (including all interferons) within 21 days prior to initial study drug dose.
  • Prior prophylactic or therapeutic HIV-1 gp120 or 160 vaccines.
  • Rifampin, rifabutin, astemizole, loratadine, or terfenadine within 21 days prior to initial study drug dose.
  • Any unapproved investigational medication for any indication within 21 days prior to initial study drug dose.


  • AZT therapy at some time prior to screening. Active substance abuse.
