 AB    R89439 (loviride) is the most potent product of the alpha-APA series (A
       group of Non Nucleoside Reverse Transcriptase Inhibitors) with an IC50
       of 1.7 ng/ml and good oral bioavailability (Cp at 8h = 130 ng/ml).
       OBJECTIVES: The objectives of the present trial were to document the
       possible pharmacokinetic interactions between loviride on zidovudine and
       to assess the safety of the combination therapy of loviride 50 mg or 100
       mg t.i.d. with zidovudine. METHODS: 18 patients were randomized in three
       groups of 6 patients in a double blind, double dummy placebo-controlled
       clinical trial. Patients received either loviride 100 mg t.i.d., 50 mg
       t.i.d. or placebo together with zidovudine. HIV1-positive patients with
       CD4 > 50 and < 350 CELLS/mm3 were eligible if they had taken zidovudine
       since more than 18 months. RESULTS: It was concluded that the
       pharmacokinetics of zidovudine were not affected by cotreatment with
       loviride 50 and 100 mg t.i.d. Sofar the codes have not been broken for
       the interim safety analysis. The incidence of adverse events was not
       significantly different between the three treatment groups, except for
       diarrhea which was only reported in one group. No clinically important
       laboratory changes were noted except for increased liver enzymes in one
       group, which progressively normalised after discontinuation of
       treatment. CONCLUSION: Adverse experiences although numerous were mostly
       mild to moderate. The complete safety and efficacy results will be
       reported at the conference.
