A Randomized Trial to Evaluate the Safety and Efficacy of Combination Therapy With Retrovir ( AZT ) and HIVID ( ddC ) Versus Retrovir, HIVID, and Wellferon ( Interferon Alfa-n1 ) for the Treatment of HIV Infection

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Primary: To determine whether the combination of zidovudine/zalcitabine/interferon alfa-n1 (Retrovir/HIVID/Wellferon) can produce complete responses (i.e., CD4 counts return to >= 800 cells/mm3 for more than 24 weeks) in patients with virus sensitive to all three agents. To determine the antiviral effect of the combination therapies as evidenced by measures of quantitative viral load performed at select study centers only.

Secondary: To determine the effectiveness of Retrovir/HIVID and Retrovir/HIVID/Wellferon in maintaining or increasing CD4 counts and preventing disease progression as evidenced by the development of an AIDS-defining indicator disease. To determine the effect of these regimens on secondary measures of clinical status (e.g., performance score, weight change, and secondary infections) and on measures of virologic activity such as serum p24 antigen. To assess the safety and tolerance of these regimens.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

Criteria

Inclusion Criteria

Patients must have:

• HIV infection documented by licensed ELISA confirmed by Western blot; OR positive HIV culture; OR positive HIV antigen; OR plasma viremia.
