- Assessment of understanding: volunteer demonstrates understanding of this study and
completes a questionnaire prior to first study product administration with verbal
demonstration of understanding of all questionnaire items answered incorrectly
- Agrees not to enroll in another study of an investigational research agent until

sex at birth, greater than or equal to 13.0 g/dL for volunteers who were assigned male
sex at birth. For transgender participants who have been on hormone therapy for more
than 6 consecutive months, determine hemoglobin eligibility based on the gender with
which they identify (ie, a transgender female who has been on feminizing hormone
therapy for more than 6 consecutive months should be assessed for eligibility using
the hemoglobin parameters for persons assigned female sex at birth).

approval

other study that requires non-HVTN HIV antibody testing during the planned duration of
the study
- Pregnant or breastfeeding
Vaccines and other Injections
- HIV vaccine(s) received in a prior HIV vaccine trial. For volunteers who have received
control/placebo in an HIV vaccine trial, the HVTN 128 PSRT will determine eligibility
on a case-by-case basis.
- Previous receipt of humanized or human monoclonal antibodies (mAbs), whether licensed
or investigational; the HVTN 128 PSRT will determine eligibility on a case-by-case
basis.
- Previous receipt of monoclonal antibodies against HIV
Immune System
- Immunosuppressive medications received within 30 days before first infusion (Not
exclusionary: [1] corticosteroid nasal spray; [2] inhaled corticosteroids; [3] topical
corticosteroids for mild, uncomplicated dermatitis; or [4] a single course of
oral/parenteral prednisone or equivalent at doses less than or equal to 20 mg/day and

and/or abdominal pain.
- Immunoglobulin received within 90 days before first infusion unless eligibility for
earlier enrollment is determined by the HVTN 128 PSRT
- Autoimmune disease (Not excluded from participation: Volunteer with mild, stable and
uncomplicated autoimmune disease that does not require immunosuppressive medication

exacerbation and likely not to complicate Solicited and Unsolicited AE assessments)

grave danger to the volunteer's health or well-being during the study period,
- A condition or process (eg, chronic urticaria or recent infusion with evidence of
residual inflammation) for which signs or symptoms could be confused with
reactions to the study product, or
- Any condition specifically listed among the exclusion criteria below.
- Any medical, psychiatric, occupational, or other condition that, in the judgment of
the investigator, would interfere with, or serve as a contraindication to, protocol
adherence, assessment of safety, Solicited AEs, or a volunteer's ability to give

excluded are persons with psychoses within the past 3 years, ongoing risk for suicide,
or history of suicide attempt or gesture within the past 3 years.
- Current anti-tuberculosis (TB) therapy

Well-controlled blood pressure is defined as consistently less than or equal to
140 mm Hg systolic and less than or equal to 90 mm Hg diastolic, with or without
medication, with only isolated, brief instances of higher readings, which must be
less than or equal to 150 mm Hg systolic and less than or equal to 100 mm Hg
diastolic. For these volunteers, blood pressure must be less than or equal to 140
mm Hg systolic and less than or equal to 90 mm Hg diastolic at enrollment.
- If a person has NOT been found to have elevated blood pressure or hypertension
during screening or previously, exclude for systolic blood pressure greater than
or equal to 150 mm Hg at enrollment or diastolic blood pressure greater than or
equal to 100 mm Hg at enrollment.

surgically and who, in the investigator's estimation, has a reasonable assurance of
sustained cure, or who is unlikely to experience recurrence of malignancy during the
period of the study)

volunteer has used medications in order to prevent or treat seizure(s) at any time
within the past 3 years

of the colorectal area (eg, an HSV-2 outbreak or inflamed hemorrhoids or
colitis/diarrhea), internal hemorrhoids, or any other condition noted during screening
rectal exam via anoscope or in medical history that in the opinion of the clinician
represents a contraindication to mucosal sampling.
- For those who were assigned female sex at birth (for vaginal and cervical biopsies),
any condition noted during pelvic exam via speculum or in medical history that in the
opinion of the clinician represents a contraindication to mucosal sampling (eg,
bacterial vaginosis).
- An active genital tract condition, such as an active infection or inflammation of the
genital tract (eg, genital sores or ulcers, penile or abnormal vaginal discharge,
genital warts that are symptomatic or requiring treatment) or any other condition that
in the opinion of the clinician represents a contraindication to mucosal sampling.
