Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Presence or absence of at least one adverse event related to or possibly related to nelfinavir of Grade 2 or greater severity as defined by the DAIDS Table for Grading of Severity of Adult Adverse Experiences in the gastrointestinal or hepatic category [ Time Frame: 32 Weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Development of primary or active site protease and nucleoside reverse transcriptase inhibitor-associated resistance mutations assessed using standard HIV genotype test on maternal plasma samples [ Time Frame: 32 Weeks ] [ Designated as safety issue: No ]
  • Presence or absence of at least one adverse event of Grade 3 or 4 severity in the hematologic, cardiovascular or metabolic categories defined by DAIDS Table or in the dermatologic category as defined by the Supplemental Toxicity Table [ Time Frame: 32 Weeks ] [ Designated as safety issue: Yes ]
  • Adverse pregnancy events which cannot be directly attributed to another cause other than study treatment after consultation with Pfizer Clinician and Site Investigator [ Time Frame: 32 Weeks ] [ Designated as safety issue: Yes ]
  • Adherence assessed using the NIAID ACTG Adherence Modules and by returned medication counts [ Time Frame: 32 Weeks ] [ Designated as safety issue: No ]
  • 12-hour pharmacokinetic evaluation of nelfinavir [ Time Frame: 32 Weeks ] [ Designated as safety issue: No ]
  • Maternal plasma HIV RNA [ Time Frame: 32 Weeks ] [ Designated as safety issue: No ]
  • Immunologic response as measured by CD4 and CD8 cell count [ Time Frame: 32 Weeks ] [ Designated as safety issue: No ]
