Further study details as provided by NIH AIDS Clinical Trials Information Service:

Detailed Description:
Patients are randomized to receive either MKC-442 or placebo, along with stavudine(d4T), didanosine(ddI), and hydroxyurea. Patients will be treated and followed for 48 weeks.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria

Concurrent Medication:


- Based on medical history, medical condition, prior use of antiretroviral drugs, and genotypic analysis of the predominant strain of HIV-1 isolated from the plasma, administration of a combination of two or more available antiretroviral agents by prescription may be given with MKC-442.

Patient must have:

  • HIV infection with HIV-1 RNA greater than or equal to 5,000 by Roche Amplicor method within 30 days of entry.
  • A failed protease inhibitor-containing regimen.
  • Negative serum beta human chorionic gonadotropin test within 30 days of entry.

Prior Medication:


  • Prior nucleoside reverse transcriptase and protease inhibitors.
  • Cytotoxic chemotherapy more than 30 days prior to entry.

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

  • Malabsorption or severe chronic diarrhea within 30 days prior to entry, or inability to consume adequate oral intake because of chronic nausea, emesis, or abdominal or esophageal discomfort.
  • Inadequately controlled seizure disorder.
  • Known intolerance to stavudine, didanosine, and/or hydroxyurea.
  • Acute and clinically significant medical event within 30 days of screening.
  • Any clinical or laboratory abnormality greater than Grade 3 toxicity, with the exception of laboratory values given.

Concurrent Treatment:


- Any experimental antiretroviral therapy or immunomodulators directed against HIV-1, e.g., IL-4, cyclosporine steroids at doses greater than 40 mg/day.

Prior Medication:


- Non-nucleoside reverse transcriptase inhibitor therapy.

Prior Treatment:


  • Radiation therapy within 30 days of entry except to a local lesion.
  • Transfusion of blood or blood products within 21 days of screening.
  • Cytotoxic therapy within 3 months of study entry.

Risk Behavior:


Active substance abuse that may interfere with compliance or protocol evaluations.
