         11. Male subjects must refrain from sperm donation from clinic admission, throughout the
             study period, and continuing for at least 90 days following the last dose of study
             drug.

         12. Subjects must refrain from blood donation from clinic admission, throughout the study
             period, and continuing for at least 30 days following the last dose of study drug.

         13. Must be willing to comply with contraception guidelines below Contraception:

             The fetal risks associated with ANS-6637 are not known, but pre- clinical animal data
             demonstrate some risk. Subjects must agree not to become pregnant or impregnate a
             female. Females of childbearing potential must have a reproductive risk assessment
             done to determine the risk of undetectable pregnancy at study start [i.e. sexual and
             contraceptive history for 30 days preceding screening] pregnancy test at screening and
             baseline (Day 0). For the duration of the study, subject and their partners must
             practice two non-hormonal methods of birth control, having begun no less than 30 days,
             without interruption, prior to screening. They must continue to use both methods until
             3 months after stopping the study drug. Two of the three methods of birth control
             listed below MUST be used, or an alternative combination offering very high efficacy,
             per the PI, in consultation with the Sponsor Medical Monitor may be considered:

               -  Male or female condoms [but not both] with a spermicide

               -  Diaphragm with a spermicide

               -  Intrauterine device (IUD)

             If pregnancy is suspected or should occur, subjects must notify the study staff
             immediately.

         14. Must, in the opinion of the Investigator, be in good health based upon medical history
             and physical examination, and screening laboratory evaluations.

         15. Judged to be healthy based on medical history, physical examination, vital signs, and
             clinical laboratory tests at screening and Day 0: liver function tests (AST, ALT,
             Tbili) less than or equal to upper limit of normal [ULN], platelets (PLT) >150,000/
             microliter, hemoglobin (Hgb) >13 g/dL (males); >12 g/dL (females), CK less than or
             equal to 2x ULN, Amylase/lipase < ULN, thyroid function tests [TSH and T4] within
             normal range, fasting total cholesterol <240 mg/dL, or fasting triglycerides <240
             mg/dL, per DAIDS AE table and Toxicity Grading Scale for Healthy Adult and Adolescent
             Volunteers Enrolled in Preventive Vaccine Trials AE table for total bilirubin [Tbili]

Patient description (medical language): A 19-year-old girl comes to the clinic due to a left wrist mass.  She noticed swelling on the top of her wrist about 4 months ago and came to the clinic due to cosmetic concerns.  Examination shows a nontender, rounded mass on the dorsal wrist that transilluminates with a penlight. Vital signs are normal. The patient needs to type on her computer almost all day. She is left-handed. She does not smoke or use illicit drugs. She is in sexual relationship with two male partners and uses condoms.

Patient description (patient's own words): I'm a 19-year-old girl and I went to see my doctor because of a mass on my left wrist. I noticed a swelling on top of my wrist, like 4 months ago, and I went the first time to the doctor because it was pretty ugly! My wrist was not tender, and the mass was round and let the light go through when the doctor used a penlight. My blood pressure, breathing and temperature were normal. I'm left-handed and I need to be on my PC all day. I don't smoke or do drugs. I'm sexually active and I have 2 male partners but they all use condoms.

Does the patient match the trial criteria? Entailment
