 AB    OBJECTIVES: To evaluate in patients with AIDS the possible benefit of
       switching to didanosine after 6-18 months of AZT treatment in terms of
       survival and onset of new AIDS-defining diseases. METHODS: Multicenter,
       open, randomized study. AIDS patients with at least 6 months of AZT
       therapy, with no major intolerance, were randomly assigned to continue
       AZT or be switched to DDI. Major end-points for efficacy were survival
       and development of new AIDS-defining diseases. Major end-points for
       toxicity were adverse events leading to discontinuation of treatment.
       RESULTS: The study started in September 1990. Follow-up closure date was
       July 31, 1993. Mean follow up was 16 months. Baseline characteristics of
       patients enrolled are outlined below (Table 1): The results of a
       survival analysis performed on an intention to treat approach are
       reported below (Fig. 1). The CD4 response for the two groups is shown in
       Fig.2. CONCLUSION: Results do not show significant benefit in terms of
       survival in DDI-switched patients. Switching to DDI, however, seems to
       delay the decrease in CD4+ count. TABULAR DATA, SEE ABSTRACT VOLUME.
