The Safety and Effectiveness of Retrovir Plus HIVID Combined With Either Nevirapine or Invirase in the Treatment of HIV Infection

Administration of three-drug combinations for treatment of HIV infection is preferred over monotherapy or duotherapy. A system has been designed to rapidly evaluate current multidrug combinations of antiretrovirals and allow the addition of new agents as they become available.

Patients are randomized to receive AZT/ddC either alone or in combination with nevirapine or Ro 31-8959 for a minimum of 48 weeks. Patients are followed at weeks 2 and 4 and every 4 weeks thereafter.

• Saquinavir (Drug)
