until she is in a postmenopausal state for 12 consecutive months (without an
alternative medical cause) or otherwise permanently sterile (for which acceptable
methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy). A

prior to first study treatment administration, and condom for the male partner;
3. Simultaneous use of diaphragm or cervical cap and male condom for the male
partner, started at least 28 days prior to first study treatment administration;
4. Sterile male partner (vasectomized since at least 6 months prior to first study
treatment administration);
5. True abstinence, defined as no sexual intercourse with a male partner, (for
heterosexual couples) for at least 28 days prior to first study treatment
administration and for at least the duration of the study. Periodic abstinence
and withdrawal are not acceptable methods.
- WOCBP must have a negative urine pregnancy test prior to receiving each dose.
- Male subjects (including men who have had a vasectomy) with a pregnant partner, a
female partner not of childbearing potential, or a same sex partner, must agree to use
a condom from the first study treatment administration until at least 90 days after
the last study treatment administration.
- Male subjects must be willing not to donate sperm until 90 days following the last
study treatment administration.
- Must be able to attend all visits for the duration of the study and to comply with all
study procedures according to the study schedule.
- Capable of, and have given, written informed consent.

examination (including baseline high blood pressure [140/90] after 3 repeated
measurements or high random blood sugar [non-fasting]), clinically significant
abnormal laboratory test results or positive test for HIV, hepatitis B, or hepatitis C
found during medical screening (Part 1); Any clinically significant abnormality or
vital sign abnormality at physical examination, or uncontrolled hypertension in adults
aged = 56 years and older ,or high random blood sugar [non-fasting]), clinically
significant abnormal laboratory test results or positive test for HIV, hepatitis B, or
hepatitis C found during medical screening (Part 2).
- Any acute or chronic ongoing illness which, in the judgement of the investigator, may
preclude the subject's participation.

nasal/oropharyngeal swab and/or positive serum antibody response) at screening, or Day
1, or has been in close contact with someone who has an active COVID-19 infection, or

limited to, HIV, autoimmune disorders, immunosuppressant therapy, and diabetes

during the conduct of the study.
- Use of medications for the timeframes specified below, with the exception of hormonal
contraceptives and medications exempted by the Investigator on a case-by-case basis
