NCS as specified by the testing laboratory at Screening and admission.
7. Participants must be non-smokers or social smokers who only used nicotine on 5

Screening and admission.
9. Participants must have no relevant dietary restrictions and be willing to consume
standard meals provided.
10. Participants must have good venous access.
11. Females must be not be pregnant and lactating, and must use an acceptable, highly
effective double contraception from Screening until study completion, including the
Follow-up period unless surgically sterile. Double contraception is defined as a
condom AND one other form of the following:
- Established hormonal contraception (with approved oral contraceptive pills
[OCPs], long-acting implantable hormones, injectable hormones);
- A vaginal ring or an intrauterine device (IUD);
Participants that are surgically sterile must have documented evidence of surgical
sterilization at least 6 months prior to Screening (e.g., tubal occlusion,
hysterectomy, bilateral salpingectomy, or bilateral oophorectomy for women or
vasectomy for men [with appropriate post-vasectomy documentation of the absence of
sperm in semen] provided the male partner is a sole partner).
Women not of childbearing potential must be post menopausal for = 12 months. Post
menopausal status will be confirmed through testing of follicle-stimulating hormone
(FSH) levels = 40 IU/L at Screening for amenorrhoeic female participants. Females who
are abstinent from heterosexual intercourse will also be eligible.
Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods)
and withdrawal are not considered highly effective methods of birth control.
Participant complete abstinence for the duration of the study and for 1 month after
the last study treatment is acceptable.
Female participants who are in same-sex relationships are not required to use
contraception.
Males must be surgically sterile (> 30 days since vasectomy with no viable sperm),
abstinent, or if engaged in sexual relations with a woman of childbearing potential
(WOCBP), the participant and his partner must use an acceptable, highly effective
contraceptive method from Screening until study completion, including the Follow-up
period. Acceptable methods of contraception include the use of condoms and the use of
an effective contraceptive for the female partner that includes: OCPs, long acting
implantable hormones, injectable hormones, a vaginal ring, or an IUD. Participants
with same-sex partners (abstinence from penile-vaginal intercourse) are eligible when
this is their preferred and usual lifestyle.
WOCBP must have a negative pregnancy test at Screening and Day 1 and be willing to
have additional pregnancy tests as required throughout the study.
12. Males must not donate sperm and females must not donate ova for at least 90 days after
the last dose of study drug.
13. Participants must have the ability and willingness to attend the necessary visits to
the clinical research unit (CRU).
Exclusion Criteria:

any time during the study, including the Follow-up period.

renal, hepatic, hematologic, lymphatic, neurological, cardiovascular, psychiatric,
musculoskeletal, genitourinary, immunological, dermatological, endocrine, connective
tissue diseases or disorders.
3. Presence of any underlying physical or psychological medical condition that, in the
opinion of the Investigator, would make it unlikely that the participant will comply
with the protocol or complete the study per protocol.
4. Have a Fridericia's correction factor for QT (QTcF) > 450 ms for male participants and
> 470 ms for female participants or history of QT interval prolongation.
