To be eligible for this study, a participant has to meet all of the following inclusion
criteria:

1. being of non-Chinese, European descent
2. having origins in any of the black racial groups of Africa
3. being of Cuban, Mexican, Puerto Rican, Cuban, South or Central American, or other
Spanish culture or origin, regardless of race
4. having two Han Chinese biological parents;
2. Is capable of giving informed consent and complying with study procedures;
3. Healthy male or female participants, between the ages of 18 and 65 years, inclusive at
the time of informed consent;
4. Body mass index (BMI) of 18.0 to 34.9 kg/m2 inclusive and body weight not less than 50
kg;
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)
- Combined (estrogen and progestogen containing) hormonal contraception (oral,
intravaginal, transdermal, injectable)
- Progestogen-only hormonal contraception (oral, injectable, implantable)
- Implantable device (implantable rod or intrauterine device)
- Bilateral tubal occlusion Alternatively, females of childbearing potential
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
Screening until at least 90 days after EQ143 treatment. It is not necessary
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
in relation to the duration of the clinical trial and the preferred and
usual lifestyle of the participant.
Participants must agree to not donate sperm or ova from time of EQ143 administration
until 90 days after EQ143 treatment.
6. Male participants must agree to utilize a highly effective method of contraception
(condom) during heterosexual intercourse from CRU admission until 12 weeks following
the final Follow-up visit on Day 10 and must refrain from donating sperm for this same
period;
7. Considered healthy by the Investigator, based on participant's reported medical
history, full physical examination, clinical laboratory tests, 12-lead ECG, and vital
signs;
8. Willing and able to adhere to study restrictions and to be confined at the clinical
research center;
9. Participants willing to defer receiving prophylactic live immunizations during the
duration of the study. Participants may receive vaccination for SARS-CoV-2 at the
discretion of the Investigator as soon as they are eligible, and a vaccine is
available. If and when possible, the inactivated mRNA-based vaccines are recommended.

triplicate if initial results exceed these values, and the average value should be
used to determine eligibility;
13. Fever (body temperature > 38°C) or symptomatic viral or bacterial infection within 2
weeks prior to Screening. PCR testing for SARS-CoV-2 infection will be performed in
accordance with local guidelines (health authorities, Institutional Review
Boards/Independent Ethics Committees, and study center policies) and at the discretion
