Further study details as provided by Bristol-Myers Squibb:

Primary Outcome Measures:
  • Steady state pharmacokinetics of atazanavir/ritonavir 300/100mg & 400/100mg each co-administered w/ nevirapine 200mg twice-daily w/ 2 to 3 nucleoside reverse transcriptase inhibitors relative to that of a second cohort of subj.

Secondary Outcome Measures:
  • Steady state PK of 2 atazanavir/ritonavir&nevirapine regimens relative to historic data of atazanavir 400mg in HIV-inf subj;Safety & tolerability of co-admin of atazanavir,ritonavir,&nevirapine in the presence of 2to3 nucleoside rev. transcriptase inhibi
