5. Female participants must have a negative serum pregnancy test result at Screening and
negative urine pregnancy test at admission to the study site, are not currently
breastfeeding, and meet one of the following criteria:

1. Surgically sterile for at least 3 months prior to Screening by one of the
following means:

- Bilateral tubal ligation

- Bilateral salpingectomy (with or without oophorectomy)

- Surgical hysterectomy

- Bilateral oophorectomy (with or without hysterectomy)

2. Postmenopausal, defined as the following:

- Last menstrual period greater than 12 months prior to Screening without an
alternative medical cause, AND

- Postmenopausal status confirmed by serum Follicle-stimulating hormone (FSH)
concentration at Screening > 40 mIU/mL

3. Female participants of childbearing potential must use at least one of the
following protocol-specified highly effective methods of birth control, AND must
agree to use barrier contraception (male condom) during heterosexual intercourse,
from the time of Screening until at least 90 days after EQ143 treatment:

- Infertile male partner (eg, vasectomy [at least 6 months prior to Screening;
vasectomized partner should be the sole partner of the female participant],
permanently sterile following bilateral orchidectomy, or any other
documented cause of infertility)

must practice complete abstinence (defined as refraining from heterosexual
intercourse when this is in line with the preferred and usual lifestyle of
the participant; periodic abstinence and withdrawal are not acceptable) from

to use any other method of contraception when complete abstinence is
elected. Women of childbearing potential (WOCBP) who choose complete
abstinence must continue to have pregnancy tests as per protocol. The
reliability of sexual abstinence needs to be evaluated by the Investigator

Brief summary
This is an open-label and uncontrolled study to evaluate the comparative PK of EQ143

ethnic populations.

A total of one (1) single dose cohort is planned at 110 mg of EQ143. EQ143 is an approved
therapy in China at the 110 mg dose for the treatment of patients with Epidermal Growth
Factor Receptor (EGFR) T790Mmutation-positive, metastatic non-small cell lung cancer (NSCLC),
