study treatment and must agree to ongoing pregnancy testing during the course of
the study, and after end of study treatment. This applies even if the subject
practices true abstinence from heterosexual contact. AND
- Either commit to true abstinence from heterosexual contact (which must be
reviewed on a monthly basis and source documented) or agree to use, and be able
to comply with two forms of contraception: one highly effective, and one
additional effective (barrier) measure of contraception without interruption 28
days prior to starting investigational product, during the study treatment, and

is highly effective (with a failure rate of < 1% per year), preferably with low
user dependency, during the intervention period and for at least 7 months after
the last dose of study intervention. These patients must also agree not to donate
eggs (ova, oocytes) for the purpose of reproduction during this period
- Persons able to father a child must agree that during the treatment intervention
period and for 6 months after the last dose of study treatment (to allow for
clearance of any altered sperm), the participant will:

treatment, PLUS either:
- Be abstinent from heterosexual intercourse as their preferred and usual
lifestyle (abstinent on a long term and persistent basis) and agree to
remain abstinent, OR,
- Must agree to use contraception/barrier such as a male condom (even if
they have undergone successful vasectomy), and when having sexual
intercourse with a person of childbearing potential who is not
currently pregnant his partner will use an additional highly effective
contraceptive method with a failure rate of < 1% per year

HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc]
and/or antibodies to hepatitis B surface antigen [anti-HBs]) must be screened
using real-time polymerase chain reaction (PCR) measurement of hepatitis B virus
(HBV) DNA levels. Those who are PCR positive will be excluded from the study.
- NOTE: Participants with serologic findings suggestive of hepatitis B virus (HBV)
vaccination (antiHBs positivity as the only serologic marker) AND a known history
of prior HBV vaccination do not need to be tested for HBV deoxyribonucleic acid
(DNA) by polymerase chain reaction (PCR). Those who are PCR positive will be
excluded from the study

- Willing and able to adhere to the study visit schedule and other protocol
requirements. Willing to return to enrolling institution for follow-up (during the
Active Monitoring Phase of the study)

interruptions and for at least 28 days following the last dose of study treatment
