An Observational Study of Long-term Outcomes of HIV-1 Infection in Persons Who Become HIV-1 Infected After Enrollment in HIV-1 Vaccine Trials

A descriptive and observational study of long-term outcomes of HIV-1 infection in persons who
become HIV-1 infected after enrollment in HIV-1 vaccine trials

Inclusion Criteria:

- Participants must meet the following criteria in order to be eligible for inclusion in
the study:

1. Confirmation of HIV-1 infection after enrollment in an HVTN vaccine trial in
which HIV-1 infection constituted an endpoint, according to the diagnostic
algorithm specified in the parent protocol.

2. Ability and willingness to provide written informed consent to participate in the
study.

3. Ability and willingness to adhere to the on-study follow-up schedule.

4. Ability and willingness to provide adequate information for locator purposes.

5. Participants who are currently on ART or who previously received antiretrovirals
as part of post-exposure prophylaxis, pre-exposure prophylaxis, or previous
treatment regimen will be eligible for inclusion in this protocol. Their previous
treatment history will be collected. If a participant has been on ART for more
than 2 years, please consult with the protocol team leadership prior to
enrollment.

6. For participants initiating ART, agreement of participant and PHCP to initiate
potent and durable ART regimens in accordance with local and international
guidelines. Examples of potent and durable regimens are provided in Appendix H.
Participants who initiate ART not consistent with regimens outlined in Appendix H
may enroll with permission of the protocol chair or designee(s).

Exclusion Criteria:

- Persons who meet the following criteria will be excluded from the study:

1. Any medical, psychiatric, alcohol/drug dependency or other condition that, in the
judgment of the investigator, would interfere with, or serve as a
contraindication to, protocol adherence or a participant's ability to give
informed consent.

2. Participants who meet these additional criteria will be excluded from the study:

- Participants undergoing acute therapy for serious medical illnesses (in the opinion of
the site investigator) within 14 days prior to initiation of ART.

- Participants with chronic, acute, or recurrent infections that are serious (in the
opinion of the site investigator).

- Participants who must continue with chronic (maintenance) therapy (e.g., tuberculosis
[TB], pneumocystis pneumonia [PCP]), must have completed at least 14 days of therapy
and be clinically stable prior to initiation of ART.

- Oral and vaginal candidiasis, mucocutaneous herpes simplex, and other minor illnesses,
as defined by the site investigator, present no restriction to eligibility.

- Participants undergoing radiation therapy, systemic chemotherapy, or receiving an
immunomodulator within 45 days prior to initiation of ART. (A tapering course of
corticosteroids as acute therapy for PCP or other conditions is an exception.)
