- •Has any of the following laboratory abnormalities at Screening:
- •Aspartate aminotransferase (AST) or alanine transaminase (ALT) Grade 1 or higher as per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 1.0, December, 2004 (Clarification dated August 2009)
- •Calculated creatinine clearance less than 60 mL/min by the Cockcroft- Gault formula, where creatinine clearance (female) in mL/min = (140 - age in years) x (weight in kg) x (0.85)/72 x (creatinine in mg/dL)
- •Hemoglobin Grade 1 or higher as per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 1.0, December, 2004 (Clarification dated August 2009)
- •Platelet count Grade 1 or higher as per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 1.0, December, 2004 (Clarification dated August 2009) --- Note: Otherwise eligible participants with an exclusionary test result may be retested during the screening process. If a participant is re- tested and a nonexclusionary result is documented within 45 days of providing informed consent for screening, the participant may be enrolled.
- •At Screening or Enrollment, is pregnant
- •Diagnosed with urinary tract infection (UTI) at Screening or Enrollment
- •- Note: Otherwise eligible participants diagnosed with UTI during screening will be offered treatment and may be enrolled after completing treatment and all symptoms have resolved. If treatment is completed and symptoms have resolved within 45 days of obtaining informed consent for screening, the participant may be enrolled.

- •- Note: Cervical friability bleeding associated with speculum insertion and/or specimen collection judged to be within the range of normal according to the clinical judgment of the IoR/designee is considered expected non-menstrual bleeding and is not exclusionary.
- •At Screening, severe pelvic relaxation such that either the vaginal walls or the uterine cervix descend beyond the vaginal introitus with valsalva maneuver
- •Has any other condition that, in the opinion of the IoR/designee, would preclude informed consent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving study objectives.
