What this Trial Is About

To determine the safety and maximum tolerated dose (MTD) of 2',3'-dideoxy-2',3'-didehydrothymidine (d4T) administered to patients with AIDS or AIDS related complex (ARC) who are intolerant of zidovudine (AZT). The study also begins an assessment of the effectiveness of d4T therapy on HIV replication, on plasma levels of p24 antigen, and clinical or immunologic parameters associated with AIDS. Of the methods that are being evaluated to treat HIV-infected individuals, AZT has produced the best results to date. Toxic effects in approximately 50 percent of patients receiving AZT may limit its usefulness for prolonged treatment. Long-term treatment may be necessary to prevent progression of early stage HIV infection to AIDS and to prevent secondary transmission. Other drugs that may be equally or more effective than AZT and useful in the long- term treatment of HIV infection must be developed and evaluated. Test-tube and animal studies of d4T show that the drug can inhibit replication (reproduction) of HIV at concentrations similar to concentrations of AZT that have anti-HIV activity. These studies also indicate that the drug may stay in the bloodstream longer than AZT. Thus, it may be possible for the drug to be as effective as AZT when taken less frequently than AZT. It also may have a less disturbing effect on other body functions (such as thymidine metabolism).

Inclusion Criteria

Patients must have:

  • Diagnosis of AIDS or AIDS related complex (ARC).
  • Previous intolerance to daily doses of up to 1200 mg of zidovudine (AZT) demonstrated by a decrease in hemoglobin levels of 2 - 8.5 g/dl or AZT-related depression of neutrophils of 200 - 750 cells/mm3.
  • Ability to provide informed consent.

Prior Medication:

Allowed:

  • Zidovudine (AZT).

Exclusion Criteria

Co-existing Condition:

Patients with the following are excluded:

  • AIDS-defining opportunistic infection on enrollment.
  • Intractable diarrhea.
  • History of seizures within past 2 years or currently requiring anticonvulsants for control.
  • Any other clinical conditions or prior therapy which in the opinion of the investigator would make the patient unsuitable for study or unable to comply with the dosing requirements.

Concurrent Medication:

Excluded:

  • Systemic maintenance or chemoprophylaxis for opportunistic infection (includes dapsone, acyclovir).
  • Systemic therapy with this or any other antiretroviral drug (except zidovudine (AZT)) or investigational drug.
  • Ribavirin.
  • Cytotoxic anticancer therapy.
  • Any agent known as a potent inducer or inhibitor of drug-metabolizing enzymes (includes rifampin and barbiturates).
  • Trimethoprim / sulfamethoxazole (TMP / SMX).

Patients with the following are excluded:

  • AIDS-defining opportunistic infection on enrollment.
  • Intractable diarrhea.
  • History of seizures within past 2 years or currently requiring anticonvulsants for control.
  • Any other clinical conditions or prior therapy which in the opinion of the investigator would make the patient unsuitable for study or unable to comply with the dosing requirements.

Prior Medication:

Excluded within 2 weeks of study entry:

  • Any agent known as a potent inducer or inhibitor of drug-metabolizing enzymes (includes rifampin and barbiturates).

Excluded within 1 month of study entry:

  • Systemic therapy with this or any other antiretroviral drug (except zidovudine (AZT)) or investigational drug.

Excluded within 3 months of study entry:

  • Ribavirin.
