        blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels
        consistent with menopause (refer to laboratory reference ranges for confirmatory levels)].
        Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will
        be required to use one of the highly effective contraception methods if they wish to
        continue their HRT during the study. Otherwise, they must discontinue HRT to allow
        confirmation of post-menopausal status prior to study enrollment.

        Reproductive potential and agrees to follow one of the options listed in the Modified List
        of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential
        (FRP) from 30 days prior to the first dose of study medication, throughout the study, for
        at least 30 days after discontinuation of all oral study medications, and for at least 52

          -  Capable of giving signed informed consent. Eligible subjects or their legal guardians
             (and next of kin when locally required), must sign a written Informed Consent Form
             before any protocol-specified assessments are conducted. Enrollment of subjects who
             are unable to provide direct informed consent is optional and will be based on local

             only for peri-partum treatment). Subjects who are currently participating in or
             anticipate to be selected for any other interventional study with the exception of the
             201585 (ATLAS) study.

        For Subjects transitioning from 201585 (ATLAS):

          -  Subjects with moderate to severe hepatic impairment.

          -  Any pre-existing physical or mental condition (including substance use disorder)
             which, in the opinion of the Investigator, may interfere with the subject's ability to
             comply with the dosing schedule and/or protocol evaluations or which may compromise
             the safety of the subject.

          -  Subjects determined by the Investigator to have a high risk of seizures, including
             participants with an unstable or poorly controlled seizure disorder. A subject with a
             prior history of seizure may be considered for enrollment if the Investigator believes
             the risk of seizure recurrence is low. All cases of prior seizure history should be
             discussed with the Medical Monitor prior to enrollment.

          -  All subjects will be screened for syphilis (rapid plasma reagin [RPR]). Subjects with
             untreated secondary (late latent) or tertiary syphilis infection, defined as a
             positive RPR and a positive treponemal test without clear documentation of treatment,
             are excluded. Subjects with a false positive RPR (with negative treponemal test) or
             serofast RPR result (persistence of a reactive nontreponemal syphilis test despite
             history of adequate therapy and no evidence of re-exposure) may enroll after
             consultation with the Medical Monitor. Participants with primary syphilis or early
             latent secondary syphilis (acquired within the preceding year) who have a positive RPR
             test and have not been treated may be treated during the screening period and if
             completion of antibiotic treatment occurs during the screening period, may be allowed
             entry after consultation with the Medical Monitor. If antibiotic treatment cannot be
             completed before the screening window ends, subjects may be rescreened once following
             completion of antibiotic therapy for primary or early latent secondary syphilis.

          -  Subjects who, in the investigator's judgment, pose a significant suicide risk.
             Subject's recent history of suicidal behavior and/or suicidal ideation should be
             considered when evaluating for suicide risk.

          -  The subject has a tattoo or other dermatological condition overlying the gluteus
             region which may interfere with interpretation of injection site reactions.

          -  Evidence of Hepatitis B virus (HBV) infection based on the results of testing at

             (DNA) as follows:

        Subjects positive for HBsAg are excluded; Subjects negative for anti-HBs but positive for
        anti-HBc (negative HBsAg status) and positive for HBV DNA are excluded. Note: Participants
        positive for anti-HBc (negative HBsAg status) and positive for anti-HBs (past and/or
        current evidence) are immune to HBV and are not excluded.

          -  Asymptomatic individuals with chronic hepatitis C virus (HCV) infection will not be
             excluded, however Investigators must carefully assess if therapy specific for HCV
             infection is required; participants who are anticipated to require HCV treatment
             within 12 months must be excluded. (HCV treatment on study may be permitted post Week
             52, following consultation with the medical monitor).

          -  Subjects with HCV co-infection will be allowed entry into this study if: liver enzymes
             meet entry criteria; HCV Disease has undergone appropriate work-up, and is not
             advanced, and will not require treatment prior to the Week 52 visit. Additional
             information (where available) on participants with HCV co-infection at screening
             should include results from any liver biopsy, Fibroscan, ultrasound, or other fibrosis
             evaluation, history of cirrhosis or other decompensated liver disease, prior
             treatment, and timing/plan for HCV treatment; In the event that recent biopsy or
             imaging data is not available or inconclusive, the Fib-4 score will be used to verify
             eligibility: Fib-4 score >3.25 is exclusionary; Fib-4 scores 1.45 - 3.25 requires
             Medical Monitor consultation; Fibrosis 4 Score Formula:

             the Study medical monitor for inclusion of the participant prior to randomization.

          -  Any condition which, in the opinion of the Investigator, may interfere with the
             absorption, distribution, metabolism or excretion of the study drugs or render the

          -  History or presence of allergy or intolerance to the study drugs or their components

             result.

          -  Any verified Grade 4 laboratory abnormality. A single repeat test is allowed during
             the Screening phase to verify a result.

          -  Any acute laboratory abnormality at Screening, which, in the opinion of the
             investigator, would preclude the subject's participation in the study of an
             investigational compound.
